Based on the classical references cited (Su.U.7, Va.U.12, A.Sa.U.15), Timira is categorized according to which Patala (layer) is affected by the vitiated Dosha. In diabetic retinopathy, the primary analogy is with Dwitiya Patala Gata Timira (involving the vitreous/inner retinal layer) and Tritiya Patala involvement (deeper retinal/choroidal layer).

Timira symptoms corresponding to Prathama or Dwitiya Patala Gata

Exclusion:

PDR with vitreous hemorrhage or tractional RD
CMT > 500 µm with centre-involving DME requiring immediate laser/anti-VEGF
NVI / Neovascular glaucoma
Other concurrent ocular diseases (ARMD, CRAO, glaucoma)
Systemic diseases causing retinopathy (hypertensive, sickle cell)

Key Notes for the Study Protocol

Primary endpoint (Ayurvedic): Reduction in Timira Patala Symptom Score (SSS) — specifically Dwitiya Patala features (floaters, metamorphopsia, near-vision difficulty) mapping to early–moderate NPDR/DME
Primary endpoint (Modern): Change in BCVA (LogMAR) and CMT (OCT) from baseline to end of treatment
Secondary endpoints: Change in ICDRDS grade, HbA1c, FBS, IOP, Amsler grid score
Vasadi Kwath contains drugs with documented Chakshushya, Rasayana, Tridoshashamaka, and Medhya properties — the mechanism of action should be correlated with anti-VEGF, anti-inflammatory, and neuroprotective pathways in the discussion
Statistical analysis: Wilcoxon signed-rank test for non-parametric ordinal scores (SSS, ICDRDS grade); paired t-test for BCVA (LogMAR) and CMT; Pearson correlation between HbA1c change and CMT/BCVA change

This framework provides a complete, IRB-ready set of subjective and objective assessment parameters that bridges classical Timira Patala theory with modern diabetic retinopathy grading, suitable for submission to a Postgraduate / PhD research committee.

Effect of Vasadi Kwath in Timira w.s.r. to Diabetic Retinopathy

PART A — ETIOLOGICAL FACTORS (NIDANA)

A.1 — Ayurvedic Etiological Factors (Nidana) for Timira

Based on Sushruta Uttaratantra, Vagbhata Uttaratantra and Ashtanga Sangraha:

A.1.1 Aaharaj Nidana (Dietary Causes)

Sr.	Nidana (Cause)	Category	Modern Correlation
1	Ati Amla Sevana	Excess sour intake	Increases Pitta, retinal oxidative stress
2	Ati Lavana Sevana	Excess salt	Hypertension → vascular damage

2	Beeja-dosha (genetic)	Family history of DM / DR
3	Prameha (DM) as Poorvaroopa	Prameha Upadrava — Timira is a complication of Prameha

A.2 — Modern Etiological / Risk Factors for Diabetic Retinopathy

A.2.1 Non-modifiable Risk Factors

Sr.	Factor	Detail
1	Duration of Diabetes	Greatest single predictor; >20 years DM → ~99% T1DM, ~60% T2DM develop some DR
2	Type of Diabetes	T1DM develops PDR more rapidly; T2DM more common due to prevalence
3	Age of onset	Younger onset → longer lifetime exposure
4	Genetic predisposition	Family history of DR; polymorphisms in VEGF, RAAS genes
5	Ethnicity	Higher prevalence in South Asian, Hispanic, African-American populations
6	Puberty	Rapid DR progression during puberty in T1DM (DCCT data)

A.2.2 Modifiable Dietary & Metabolic Risk Factors (Primary Focus for Your Study)

Sr.	Dietary / Metabolic Factor	Mechanism of DR Progression
1	High Glycemic Index / Load Diet	Postprandial hyperglycemia → AGE (Advanced Glycation End-products) formation → pericyte loss, BM thickening
2	Excess Refined Carbohydrate Intake	Sustained hyperglycemia → oxidative stress → VEGF upregulation → neovascularization
3	High Saturated Fat / Trans Fat	Dyslipidemia → hard exudate deposition in macula → DME
4	Dietary Cholesterol excess	LDL oxidation → retinal lipid deposition; associated with CSME severity
5	Low Dietary Antioxidant Intake	Deficiency of Vit C, E, lutein, zeaxanthin → increased retinal oxidative damage
6	Low Omega-3 Fatty Acids	Pro-inflammatory state → retinal microangiopathy
7	Excess Sodium / Salt intake	Hypertension (BP >130/80) → 3× increased DR progression risk
8	Excess Alcohol consumption	Hepatotoxicity → dyslipidemia; direct retinal toxin
9	Tobacco / Smoking	Nicotine → vasoconstriction, hypoxia → PDR acceleration
10	Obesity / Central Adiposity	Insulin resistance → hyperinsulinemia → VEGF/IGF-1 → neovascularization
11	Iron excess (red meat)	Promotes free radical generation → retinal oxidative stress
12	Low dietary Zinc intake	Zinc is co-factor for retinal antioxidant enzymes (SOD); deficiency → DR

REVIEW OF LITERATURE

Purvarupa, Rupa, and Patala Gata Lakshanas of Timira

w.s.r. to Diabetic Retinopathy

SECTION I — PURVARUPA (PRODROMAL SYMPTOMS) OF TIMIRA

1.1 Classical Definition of Purvarupa

Purvarupa is defined as those symptoms which appear before the complete manifestation of a disease. They are incomplete manifestations of the Rupa (cardinal symptoms) and serve as warning signs of impending disease.

"Dosha dushyasamoorchana purvarupa prakashate" — Charaka Samhita, Nidanasthana 1

"Vyaktam purvarupa syadavyaktam rupa darshanam" The Purvarupa are avyakta (indistinct) manifestations of what will become vyakta (distinct) Rupa.

1.2 Purvarupa of Timira — Classical References

From Sushruta Uttaratantra

"Akshibhyam shoolam toda spandanam daha nishprabhatvam cha parikledam ch" — Su.U. 7 (Preamble to Timira Nidana)

From Vagbhata Uttaratantra (Va.U.12)

"Shoola toda spandana daha nishprabhatvam lohitabhasa cha purva rupam"

From Ashtanga Sangraha Uttarasthana (A.Sa.U.15)

"Timire purva rupani — akshi toda, akshi shula, vaivarnya, klama netrayo"

1.3 Purvarupa — Tabulated (All Classical Sources)

Sr.	Purvarupa	Literal Meaning	Clinical Interpretation	Modern Correlation
1	Akshi Toda	Pricking pain in eyes	Sharp, needle-like pain	Retinal ischemia-related pain, asthenopia
2	Akshi Shoola	Pain in eyes	Dull or throbbing eye pain	Raised IOP, ciliary muscle strain
3	Akshi Spandana	Twitching / pulsation of eyes	Involuntary eyelid/eye twitching	Myokymia, retinal vascular pulsation
4	Daha	Burning sensation in eyes	Burning, gritty feeling	Dry eye, corneal involvement
5	Nishprabhatvam	Loss of lustre / brightness	Dimming of vision, loss of contrast	Reduced contrast sensitivity — early DR
6	Parikledam	Excess lacrimation / watering	Watering from eyes	Lacrimal pathway involvement
7	Vaivarnya	Discolouration of eye	Redness or dullness of sclera/conjunctiva	Conjunctival vessel engorgement
8	Klama netrayo	Fatigue of eyes	Eye tiredness, asthenopia	Digital eye strain, accommodative fatigue
9	Lohitabhasa	Reddish tinge in vision	Seeing reddish tint	Vitreous micro-hemorrhage — early PDR signal
10	Mandadrishti	Sluggish / slow vision	Gradual decrease in vision	Subclinical visual acuity reduction in pre-DR
11	Timira Pratibhasaha	Momentary darkness	Transient darkening of vision	Transient ischemic events / orthostatic hypotension in DM

1.4 Purvarupa — Modern Correlation (Pre-DR / Subclinical DR Stage)

As confirmed by Diabetic Retinopathy (p.12): "Retinal neurodegeneration is an early event in the pathogenesis of DR, which could contribute to the development of microvascular abnormalities... defects in neurosensory structure and function have been demonstrated via OCT and psychophysical testing in patients with DM prior to onset of vascular lesions."

This directly parallels the Ayurvedic concept of Purvarupa — functional/neurological changes precede structural vascular lesions, just as Purvarupa precede Rupa.

Purvarupa (Ayurvedic)	Modern Pre-DR / Subclinical Finding
Nishprabhatvam (loss of lustre)	Reduced contrast sensitivity (Pelli-Robson)
Mandadrishti	Subclinical BCVA reduction on LogMAR testing
Klama netrayo (eye fatigue)	Accommodative insufficiency in DM
Akshi toda / shoola	Retinal neurodegeneration-related discomfort
Lohitabhasa	Subclinical microhemorrhages on OCT-A
Timira Pratibhasaha	Transient visual obscurations
Daha	Dry eye / corneal neuropathy (diabetic keratopathy)

SECTION II — RUPA (CARDINAL SYMPTOMS) OF TIMIRA

3.2 PRATHAMA PATALA GATA TIMIRA

Classical References

Sushruta Uttaratantra 7/6:

"Tiraabhirabhisampraapya vigunoabhyantare bhrisham | Prathame patale dosho yasya drishtau vyavasthitah || Avyaktaani sa rupaani sarvaanyeva prapashyati"

Vagbhata Uttaratantra 12/1:

"Shiranusaarini male prathamam patalam shrite | Avyaktameekshate roopam vyaktamapyanimittathah"

Ashtanga Sangraha Uttarasthana 15/1:

Same verse as Va.U.12/1

Dalhana's Commentary (on Su.U.7/6):

"Timiraarambhakadosha sya sampraaptileshapoorvakam lakshanam" — This describes the initial stage of Timira; the dosha having just entered via the Siras (vessels) reaches the first Patala causing subtle symptoms.

Prathama Patala Gata — Symptom Table

Sr.	Lakshana	Shloka Reference	Meaning	Modern Correlation
1	Avyakta Darshana	Su.U.7/6; Va.U.12/1	All objects appear indistinct / blurred	Reduced BCVA — subclinical; 6/9 to 6/12
2	Vyakta rupa api avyaktavat	Va.U.12/1	Even clearly visible objects appear blurred without reason	Intermittent blurring — early macular dysfunction
3	Sarva rupa avyakta	Su.U.7/6	All types of objects indistinct	Non-specific blurring in all distances
4	Symptom onset insidious	Dalhana commentary	Gradual imperceptible onset	Asymptomatic early DR — detected only on fundus exam

Pathological Basis (Samprapti): Vitiated Doshas (primarily Pitta with Vata) travel via the Siras (retinal vessels), reach the Prathama Patala (cornea/anterior segment) and cause mild dysfunction of the Tejojala (aqueous-corneal clarity). The Tejas (visual light/Alochaka Pitta) is mildly impaired.

Modern Equivalent: Early NPDR — microaneurysms only. No symptoms in majority; some patients report occasional blurring. Neurodegeneration detectable on OCT before visible vascular lesions (Diabetic Retinopathy, p.12).

Dalhana's Commentary (on Su.U.7/7–10):

"Timiraarambhaka dwitiya patalaadhita dosha prabhavena makshikaadeeni yathadosha varnaani pashyati" — The floaters and visual disturbances are coloured according to the predominant Dosha (Vata = black/grey, Pitta = yellow/red, Kapha = white/pale).

3.5 CHATURTHA PATALA GATA TIMIRA (LINGANASHA — Pre-blindness)

Classical References

Sushruta Uttaratantra 7/12:

"Na pashyati chaturtham tu praapte andho bhavati dhruvam | Linganasham tamasteeram tatra vidyaanna bhesha jam ||"

Vagbhata Uttaratantra 12/7:

SECTION IV — COMPREHENSIVE COMPARATIVE TABLE

Purvarupa → Rupa → Patala Gata Lakshana → Modern Equivalent

Stage	Ayurvedic	Classical Reference	Modern Stage	Key Clinical Finding
Purvarupa	Akshi toda, daha, nishprabhatvam, klama, spandana	Su.U.7 (preamble); Va.U.12	Pre-DR / Subclinical DR	Neurodegeneration on OCT, reduced contrast sensitivity, no vascular lesions
Rupa (General)	Avyakta darshana, floaters, photopsia, diplopia	Su.U.7/6–10; Va.U.12/1–5	Any stage NPDR	Symptoms varying with Dosha and Patala
Prathama Patala	Avyakta darshana only; vyakta api avyakta	Su.U.7/6; Va.U.12/1	Mild NPDR	Microaneurysms; BCVA 6/9–6/12; subclinical
Dwitiya Patala	Floaters, photopsia, metamorphopsia, diplopia, near-work difficulty	Su.U.7/7–10; Va.U.12/2–5	Moderate–Severe NPDR + DME	Dot-blot hge, HE, CWS, venous beading, DME; BCVA 6/18–6/60
Tritiya Patala	Central scotoma, near-blindness, severe distortion	Su.U.7/11; Va.U.12/6	Severe NPDR + CSME	Centre-involving DME, macular ischemia; BCVA 6/60–3/60
Chaturtha Patala	Complete blindness — Linganasha	Su.U.7/12; Va.U.12/7	PDR + TRD / NVG	Vitreous hge, tractional RD, NVG; PL/NPL

SECTION V — SADHYASADHYATA (Prognosis Classification)

Patala	Prognosis	Condition	Modern Analogy
Prathama	Sadhya (Curable)	Doshas not yet deeply embedded	Early NPDR — fully reversible with good control
Dwitiya	Kashta Sadhya (Difficult to cure)	Doshas in lens/vitreous	Moderate NPDR + DME — treatable but recurs
Tritiya	Yapya (Palliable)	Doshas in retina	Severe NPDR + CSME — controllable, not curable
Chaturtha	Asadhya (Incurable)	Doshas destroyed Drishti	PDR + TRD + Linganasha — blindness permanent

This Sadhyasadhyata directly justifies the study's inclusion criteria — only Prathama and Dwitiya Patala Gata cases (Sadhya and Kashta-Sadhya) are included, where therapeutic intervention with Vasadi Kwath is most likely to show measurable benefit.

SECTION VI — MODERN DISEASE DEFINITION (For ROL)

As per Diabetic Retinopathy (p.12):

"Diabetic retinopathy is the ocular manifestation of end-organ damage in diabetes mellitus. Growing evidence suggests that retinal neurodegeneration is an early event in the pathogenesis of DR which could contribute to the development of microvascular abnormalities."

This aligns with the Ayurvedic understanding that Purvarupa (neurological/functional prodrome) precede Rupa (structural vascular changes), validating the classical framework with modern evidence.

Progression of DR (Diabetic Retinopathy, p.17):

Mild NPDR — Microaneurysms → Prathama Patala Gata
Moderate NPDR — Hemorrhages, HE, CWS → Dwitiya Patala Gata (early)
Severe NPDR — 4-2-1 rule, IRMA → Dwitiya/Tritiya Patala Gata
PDR — NVD/NVE, VH, TRD → Chaturtha Patala Gata / Linganasha

This complete ROL section is structured exactly as required for a MUHS/CCRAS postgraduate dissertation, covering:

All classical sources (Sushruta, Vagbhata, Ashtanga Sangraha)

(Diabetic Retinopathy, i`"B 12 ds vuqlkj)

"Diabetic retinopathy is the ocular manifestation of end-organ damage in diabetes mellitus. Growing evidence suggests that retinal neurodegeneration is an early event in the pathogenesis of DR, which could contribute to the development of microvascular abnormalities. Although defects in neurosensory structure and function have been demonstrated via OCT and psychophysical testing in patients with DM prior to onset of vascular lesions, the most common early DR manifestations that are clinically visible include microaneurysm formation."

Here is a complete, thesis-ready guide on how to compare pre and post fundus photographs in a clinical study on Vasadi Kwath / Timira w.s.r. Diabetic Retinopathy.

PRE AND POST FUNDUS PHOTOGRAPH COMPARISON

Methodology for Clinical Study — Vasadi Kwath in Timira w.s.r. Diabetic Retinopathy

PART A — STANDARDISATION OF FUNDUS PHOTOGRAPHY

Before any comparison is meaningful, both pre and post photographs must be taken under identical conditions. Any variation in technique invalidates comparison.

A.1 Photography Protocol (Standardisation Checklist)

Parameter	Standard Requirement
Camera used	Same fundus camera throughout study (Non-mydriatic / Mydriatic digital fundus camera)
Mydriasis	Tropicamide 1% + Phenylephrine 2.5% — same drops, same dose, BT and AT
Fields photographed	Minimum: Posterior pole (disc-centred + macula-centred) — ideally ETDRS 7-field
Field of view	45° or 30° — same setting BT and AT
Flash intensity	Auto or fixed — same setting
Focus	Sharp focus on retinal plane — same plane BT and AT
Image resolution	Minimum 8 megapixels digital; same camera
Image format	JPEG or RAW — same format
Laterality	Right eye then left eye — same sequence
Time of capture	Same time of day preferable (morning, fasting preferred)
Photographer	Same photographer BT and AT preferred
Patient position	Same chin-rest position, same fixation target

Reference: ETDRS 7-field stereo fundus photography is the gold standard for clinical trials (Eye Care of the Patient with Diabetes Mellitus, p.124) — modified Airlie House classification extended by ETDRS Report No.10, Ophthalmology 1991.

A.2 Fields to be Photographed

Field	Centre	What it Shows
Field 1	Optic disc	Disc margin, NVD, RNFL
Field 2	Macula (fovea centre)	Macular edema, HE, CWS, NVE
Field 3	Temporal to macula	Peripheral macula
Field 4	Superior temporal	IRMA, NVE, haemorrhages
Field 5	Inferior temporal	IRMA, NVE, haemorrhages
Field 6	Superior nasal	Haemorrhages, CWS
Field 7	Inferior nasal	Haemorrhages, venous beading

For resource-limited Ayurvedic clinical study settings, a minimum of 2 fields is acceptable:

Field 1 (Disc-centred) + Field 2 (Macula-centred) These two fields capture the majority of DR lesions relevant to NPDR staging.

PART B — WHAT TO LOOK FOR IN PRE vs POST COMPARISON

B.1 Lesion-wise Comparison Checklist

Each lesion is assessed separately in the BT and AT photograph and compared.

1. Microaneurysms (MA)

Assessment	Method
Count	Count total visible MAs in macular field (Field 2)
Distribution	Temporal / nasal / superior / inferior to fovea
Change	Increased / Same / Decreased
Grading	None / Definite (≥1 MA)
Tool	Manual count or software-assisted (VAMPIR, RetmarkerDR)

MAs appear as tiny red dots, < 125 µm, distinct margins. Reduction in MA count = positive treatment response.

2. Intraretinal Haemorrhages (Dot and Blot)

Assessment	Method
Type	Dot haemorrhages (small, round) vs Blot haemorrhages (larger, irregular)
Quadrant distribution	Note in which of 4 quadrants (superior, inferior, nasal, temporal)
Counting	Record approximate number: None / 1–5 / 6–10 / >10 per quadrant
4-2-1 Rule check	If ≥20 in all 4 quadrants → Severe NPDR
Change	Increased / Stable / Decreased / Resolved

3. Hard Exudates (HE)

Assessment	Method
Appearance	Bright yellow-white deposits, distinct margins, waxy
Location	Distance from centre of fovea — record in disc diameters (DD)
Pattern	Circinate / scattered / confluent
Area	Estimate as fraction of disc area (< 1/4 DA / 1/4–1/2 DA / > 1/2 DA)
Threat to centre	Within 500 µm of foveal centre = CSME criterion
Change	Increased / Stable / Decreased / Resolved

Reduction of hard exudate area and retreat from the foveal centre = key positive outcome in DME management.

4. Cotton Wool Spots (CWS) / Soft Exudates

Assessment	Method
Appearance	Fluffy white patches, indistinct margins, obscure vessels
Number	Record count: None / 1–3 / 4–6 / >6
Location	Quadrant-wise
Change	New / Resolving / Resolved

CWS are transient (resolve in 6–12 weeks) — resolution post-treatment is a positive sign but not specific to drug.

5. Venous Changes

Sign	Assessment	Significance
Venous Dilation	Compare calibre of major veins BT and AT	Early DR
Venous Beading	Sausage-link appearance of veins	≥2 quadrants = Severe NPDR criterion
Venous Looping	Omega or loop formation	Severe NPDR
Change	Present / Resolved / Progressed

6. IRMA (Intraretinal Microvascular Abnormalities)

Assessment	Method
Appearance	Fine tortuous vessels within retina, no leakage on FFA
Location	Quadrant-wise
4-2-1 criterion	≥1 quadrant IRMA = Severe NPDR
Change	New / Stable / Reduced / Resolved

7. Neovascularisation (NV) — For PDR cases only

Type	Location	Assessment
NVD	On or within 1 DD of disc	Area in DA fractions
NVE	Elsewhere on retina	Number of sites, area
NVI	Iris (Rubeosis)	Present / Absent
Change	Regressed / Stable / Progressed

8. Macular Changes

Finding	Assessment	Change
Macular oedema	Retinal thickening — compare with stereo photos	Reduced / Same / Increased
Hard exudate proximity to fovea	Distance in µm / DD from foveal centre	Retreated / Advancing
Foveal reflex	Present / Absent / Dull	Restored / Absent
Macular pigmentation	Normal / Disrupted

PART C — GRADING SYSTEM FOR COMPARISON

C.1 ICDR (International Clinical Diabetic Retinopathy) Scale

(Gold standard for clinical studies — Eye Care of the Patient with Diabetes Mellitus, p.124)

Grade	Level	Fundus Findings
0	No DR	No abnormality
1	Mild NPDR	Microaneurysms only
2	Moderate NPDR	More than mild; dot-blot haemorrhages, HE, CWS
3	Severe NPDR	4-2-1 rule: ≥20 IH in 4Q / VB in ≥2Q / IRMA in ≥1Q
4	PDR	NVD / NVE / VH / TRD

Comparison recorded as:

Improved = Drop of ≥1 ICDR grade (e.g. Grade 2 → Grade 1)
Stable = No change in grade
Worsened = Increase of ≥1 ICDR grade

C.2 DME Grading Scale

Grade	Level	Finding
0	No DME	No HE / thickening in posterior pole
1	Mild DME	HE distant from centre
2	Moderate DME	HE approaching centre
3	Severe DME (CSME)	HE / thickening at foveal centre

C.3 Individual Lesion Scoring Chart (For Study Use)

Fill this chart for each eye at BT and AT using the fundus photograph.

Lesion	Grading Scale	BT Score	AT Score	Change
Microaneurysms	0=None; 1=1–5; 2=6–10; 3=>10
Dot Haemorrhages	0=None; 1=Mild; 2=Mod; 3=Severe
Blot Haemorrhages	0=None; 1=<5; 2=5–10; 3=>10
Hard Exudates	0=None; 1=Distant; 2=Near fovea; 3=At fovea
Cotton Wool Spots	0=None; 1=1–3; 2=4–6; 3=>6
Venous Beading	0=None; 1=1Q; 2=2Q; 3=≥3Q
IRMA	0=None; 1=Present 1Q; 2=2Q; 3=≥3Q
Neovascularisation	0=None; 1=NVE only; 2=NVD; 3=NVD+NVI
Macular Oedema	0=None; 1=Mild; 2=Mod; 3=CSME
ICDR Overall Grade	0–4
DME Grade	0–3
FUNDUS TOTAL SCORE	Max 30

Fundus Score Interpretation:

% Change	Response
> 50% reduction	Marked improvement
26–50% reduction	Moderate improvement
1–25% reduction	Mild improvement
0%	Stable / No change
Increased	Worsened

PART D — PRACTICAL COMPARISON METHOD (Step-by-Step)

Step 1 — Side-by-Side Display

Place BT and AT photographs side by side on a computer screen or printed A4 sheet:

┌─────────────────────┐    ┌─────────────────────┐
│   PRE-TREATMENT     │    │   POST-TREATMENT    │
│   (Baseline)        │    │   (3 Months)        │
│   Field 1: Disc     │    │   Field 1: Disc     │
│   Field 2: Macula   │    │   Field 2: Macula   │
└─────────────────────┘    └─────────────────────┘
         BT                          AT

Step 2 — Masked Grading (Recommended for Research)

Mask the photographs — the grader should not know which is BT and which is AT
Two independent graders assess separately
Inter-grader agreement calculated using Kappa statistics (κ > 0.6 = good agreement)
Final grade = consensus grade

Step 3 — Lesion Annotation

On a printed photograph:

Mark MAs with red circles
Mark HE with yellow circles
Mark CWS with blue circles
Mark Haemorrhages with orange circles
Mark NV with green circles
Draw a 1-DD circle around fovea to assess CSME criterion

Step 4 — Record on Comparison Sheet

Use the Fundus Comparison Documentation Sheet (below).

PART E — FUNDUS PHOTOGRAPH COMPARISON DOCUMENTATION SHEET

PART F — HOW TO PRESENT IN THESIS / RESULTS

F.1 Qualitative Presentation

Print BT and AT photographs side by side in the thesis plate section
Label clearly: "Fig. X — Case No. XX — Right Eye — Pre-treatment (BT) and Post-treatment (AT) at 3 months"
Draw arrows pointing to key lesions: "Arrow A — Microaneurysm; Arrow B — Hard exudate; Arrow C — Blot haemorrhage"
Write a brief legend describing the change observed

F.2 Quantitative Presentation (Results Table)

Parameter	BT Mean ± SD	AT Mean ± SD	Change	p-value
Microaneurysm count
Haemorrhage score
Hard exudate score
ICDR Grade
DME Grade
Fundus Total Score

Use Wilcoxon Signed Rank Test for all ordinal fundus scores (non-parametric) Use McNemar's test for categorical change (improved / same / worsened)

F.3 Response Categories for Results (For Your Study)

Response	Criteria	No. of Patients	%
Marked Improvement	ICDR grade ↓ by ≥2 steps
Moderate Improvement	ICDR grade ↓ by 1 step
Mild Improvement	No grade change; lesion score ↓ >25%
Unchanged	No grade change; lesion score change <25%
Worsened	ICDR grade ↑ by ≥1 step

PART G — IMPORTANT NOTES FOR YOUR STUDY

Point	Guidance
Minimum requirement	If advanced fundus camera unavailable — use indirect ophthalmoscope with 90D lens + hand-drawn fundus diagram and BIO documentation at BT and AT
Photograph storage	Store all images with patient ID, date, eye, and BT/AT label
Ethics	Mention in consent form that fundus photographs will be taken and retained
Reporting	Any new NVD/NVE detected AT → refer to medical ophthalmology immediately
Colour calibration	Use white balance calibration target before each session
OCT correlation	Always correlate fundus photograph findings with OCT CMT — photograph may miss early macular oedema that OCT detects
Statistical note	Fundus grading is ordinal data → use non-parametric tests only
Masked grading	Essential for PhD-level work; at minimum, a second clinician should review all AT photographs

This complete framework gives you:

Standardisation protocol for reproducible BT/AT photographs
Lesion-wise comparison checklist for all 8 DR lesion types
Scoring chart with grades for each lesion
Documentation sheet ready to print and use
Thesis presentation guidance including statistics and response categories

please prepare masterchart with all demographics, etiological factors and all ayurvedic symptom score and all parameters

Perfect. Below is a single comprehensive MASTER CHART format you can directly use in your dissertation CRF (Case Record Form) and data entry sheet.

If you want, next I can give this in 3 ready formats:

Word CRF format (printable with page breaks),
Excel data-entry master sheet (with formulas for total scores and % improvement),
SPSS coding sheet (variable names, labels, value labels).

Excel data-entry master sheet (with formulas for total scores and % improvement),

write_file

Done. I created a ready CSV master file at:

/output/Vasadi_Kwath_MasterChart.csv

How to use in Excel

Open Excel
Go to File > Open and select the CSV above
Save as .xlsx
In row 2 onward, enter patient data

Essential formulas to paste in Excel (row 2, then drag down)

Assuming your headers remain in same order:

TOTAL NIDANA SCORE BT
=V2+W2+X2
TSSS TOTAL BT
=SUM(Z2,AD2,AH2,AL2,AP2,AT2,AX2)
TSSS TOTAL 1M
=SUM(AA2,AE2,AI2,AM2,AQ2,AU2,AY2)

B. Formulas (start row 2)

I2 =F2+G2+H2
N2 =IF(J2=0,"",((J2-M2)/J2)*100)
Q2 =IF(O2=0,"",((O2-P2)/O2)*100)
X2 =IF(V2=0,"",((V2-W2)/V2)*100)
AA2 is a data column, no formula if manually entered
AH2 =IF(AF2=0,"",((AF2-AG2)/AF2)*100)

C. Composite improvement formula

Use weighted average (editable):

TSSS 30%
BCVA 25%
CMT 25%
Fundus 20%

AI2 =IFERROR((N2*0.30 + Q2*0.25 + X2*0.25 + AA2*0.20), "")

D. Global response formula

AJ2 =IF(AI2="","",IF(AI2>75,"Marked Improvement",IF(AI2>=51,"Moderate Improvement",IF(AI2>=26,"Mild Improvement",IF(AI2>=1,"Minimal Improvement","No Improvement/Worse")))))

Copy formulas down all rows.

E. Data validation (dropdowns)

Group: 1,2
Sex: 1,2
ICDR: 0,1,2,3,4
DME: 0,1,2,3

F. Conditional formatting

%Change columns: green when >0, red when <0
AJ response column:
- Marked = dark green
- Moderate = light green
- Mild = yellow
- Minimal = orange
- No improvement/worse = red

2) Sheet: `Codebook`

Create mapping table:

Variable	Label	Type	Codes
Group	Treatment Group	Numeric	1=Vasadi, 2=Control
Sex	Sex	Numeric	1=Male, 2=Female
ICDR_BT	DR Grade Baseline	Numeric	0-4
DME_BT	DME Grade Baseline	Numeric	0-3
...	...	...	...

Also include score interpretation blocks:

TSSS severity bands
Global response interpretation bands

3) Sheet: `AutoSummary`

A. Overall summary cells

Total N: =COUNTA(DataEntry!A:A)-1
Vasadi n: =COUNTIF(DataEntry!B:B,1)
Control n: =COUNTIF(DataEntry!B:B,2)

B. Key overall means

Mean TSSS BT: =AVERAGE(DataEntry!J:J)
Mean TSSS 3M: =AVERAGE(DataEntry!M:M)
Mean TSSS % change: =AVERAGE(DataEntry!N:N)
Mean CMT % change: =AVERAGE(DataEntry!X:X)
Mean HbA1c % change: =AVERAGE(DataEntry!AH:AH)

C. Response distribution

Use COUNTIF(DataEntry!AJ:AJ,"Marked Improvement") etc.

Add pie chart for response categories.

4) Sheet: `GroupComparison`

Make two blocks: Group 1 and Group 2

A. Means by group (examples)

Vasadi mean TSSS BT:
=AVERAGEIF(DataEntry!B:B,1,DataEntry!J:J)
Vasadi mean TSSS 3M:
=AVERAGEIF(DataEntry!B:B,1,DataEntry!M:M)
Vasadi mean TSSS %change:
=AVERAGEIF(DataEntry!B:B,1,DataEntry!N:N)

Repeat for control with criteria 2.

B. Delta columns

Delta TSSS = BT - 3M for each group
Delta CMT = BT - 3M
Delta HbA1c = BT - 3M

C. Chart suggestions

Clustered column chart:
- X-axis: Outcomes (TSSS%, CMT%, HbA1c%, Fundus%)
- Series 1: Vasadi mean % improvement
- Series 2: Control mean % improvement

If you want, next message I can give you a ready Python openpyxl script that auto-generates this workbook exactly (all sheets, formulas, dropdowns, conditional formatting) so you only run one file and get the final .xlsx.
