EFFECT OF NAYANAMRUT LAUHAM ON DRUSHTIPATALGATA VYADHI WITH REFERENCE TO AGE-RELATED MACULAR DEGENERATION: A CLINICAL STUDY

1. INTRODUCTION

Vision is one of the most vital human senses, and its preservation is central to quality of life, functional independence, and socioeconomic productivity. Among the numerous ocular disorders threatening visual health globally, Age-Related Macular Degeneration (AMD) stands as one of the leading causes of irreversible central vision loss in individuals over 50 years of age.
AMD is a progressive neurodegenerative disease that primarily affects the retinal pigment epithelium (RPE) of the macula — the central, high-resolution zone of the retina responsible for fine detail, color perception, and reading. The disease typically manifests in the sixth to ninth decades of life and presents in two forms: the dry (non-exudative) form, characterized by the accumulation of drusen (abnormal lipoprotein deposits beneath the RPE within Bruch's membrane) and geographic atrophy; and the wet (neovascular/exudative) form, characterized by choroidal neovascularization, subretinal hemorrhage, and rapid central vision loss (Goldman-Cecil Medicine).
Globally, AMD affects approximately 196 million people as of 2020, and this figure is projected to rise to 288 million by 2040 (Wong et al., Lancet Global Health, 2014 [PMID: 25104651]). It accounts for approximately 8.5% of all blindness worldwide. In the United States alone, over 1.75 million persons are affected, with prevalence rising sharply after age 55. In India, AMD is an emerging public health concern, with increasing prevalence attributable to a rapidly aging population, rising rates of smoking, hypertension, dyslipidemia, and reduced access to intravitreal therapies in resource-limited settings.
Contemporary allopathic management includes intravitreal anti-VEGF injections (ranibizumab, bevacizumab, aflibercept, faricimab), photodynamic therapy, and nutritional supplementation (vitamins C, E, lutein, zeaxanthin, zinc, and copper — AREDS/AREDS2 formula). While anti-VEGF therapy has revolutionized the treatment of wet AMD — with 94.6% of patients receiving monthly injections experiencing less than 15-letter visual acuity loss at 12 months (Fleckenstein et al., JAMA, 2024 [PMID: 38193957]) — these therapies are invasive, expensive, require repeated administration, and carry risks of endophthalmitis and retinal detachment. No proven pharmacological treatment exists for dry AMD.
In the classical Ayurvedic system of medicine, conditions involving the progressive loss of central or deep visual function — particularly those involving retinal layer pathology — are classified under Drushtipatalgata Vyadhi (diseases of the Drishti Patalas, i.e., layers of the visual apparatus). According to Ashtanga Hridayam and Sushruta Samhita, the eye is composed of five Patalas (layers), and diseases affecting the 3rd and 4th Patalas — corresponding anatomically to the retina and choroid — fall under this category. AMD correlates closely with Drushtipatalgata Vyadhi due to the shared features of central visual field loss, absence of pain, gradual onset, and involvement of Vata and Pitta Doshas.
Nayanamrut Lauham is a classical Ayurvedic iron-based compound formulation (Lauha kalpana) classically described for the management of ocular diseases. The formulation is understood to act as a Rasayana (rejuvenative), Chakshushya (eye-tonic), and Tridosha-shamaka (balancing all three Doshas) preparation. Its constituent herbs and minerals are recognized for their antioxidant, anti-inflammatory, neuroprotective, and retino-protective properties — attributes that align with the pathophysiological mechanisms of AMD, including oxidative stress, RPE dysfunction, lipofuscin accumulation, and choroidal neovascularization.
Given the limitations of current allopathic therapies, the high global burden of AMD, the growing geriatric population in India, and the classical Ayurvedic understanding of Drushtipatalgata Vyadhi, there exists a compelling scientific and clinical basis to evaluate the therapeutic potential of Nayanamrut Lauham in AMD patients through a structured clinical study.

2. RATIONALE AND NEED OF THE STUDY

2.1 Global and National Burden

AMD is the third most common cause of blindness worldwide after cataract and glaucoma (GBD 2019, Lancet Global Health, 2021 [PMID: 33275949]). With India's population aged 60+ projected to reach 319 million by 2050, the burden of AMD in India is set to increase substantially. Despite this, there are no validated indigenous or Ayurvedic treatment protocols formally evaluated for AMD in India through controlled clinical trials.

2.2 Limitations of Current Management

  • Anti-VEGF therapy, while effective for wet AMD, requires monthly or bi-monthly intravitreal injections, making it inaccessible to a majority of the Indian population due to cost and infrastructure.
  • There is no proven treatment for dry AMD, which constitutes the majority (~85%) of AMD cases.
  • Long-term anti-VEGF use carries risks of tachyphylaxis, geographic atrophy progression, endophthalmitis, and retinal pigment epithelial tears.
  • Nutritional supplementation (AREDS2) provides only modest protection (20% vs 28% progression risk at 5 years) and does not reverse existing damage.

2.3 Ayurvedic Perspective and Therapeutic Gap

  • The Ayurvedic texts recognize retinal disease as Drushtipatalgata Vyadhi and prescribe specific Lauha preparations, Rasayana therapies, and Tarpana procedures.
  • Nayanamrut Lauham, a well-described classical Ayurvedic compound, contains iron-based and herbo-mineral constituents known for Chakshushya (ocular tonic), Rasayana (antioxidant-rejuvenative), and Vata-Pitta pacifying properties — all of which are pathophysiologically relevant to AMD.
  • Despite theoretical alignment, no systematic clinical trial has evaluated the safety and efficacy of Nayanamrut Lauham specifically in AMD / Drushtipatalgata Vyadhi.

2.4 Scientific Relevance

  • Several constituent herbs of classical Lauha formulations (including Triphala, Shatavari, Yashtimadhu, and Amalaki) have demonstrated antioxidant, anti-VEGF, anti-inflammatory, and neuroprotective activities in experimental models — mechanisms directly relevant to AMD pathogenesis.
  • A clinical study with standardized outcomes will contribute evidence-based validation of Ayurvedic pharmacology in retinal disease management.
Therefore, this study is designed to evaluate the clinical effect of Nayanamrut Lauham in patients of Drushtipatalgata Vyadhi with reference to AMD, with the aim of providing a safe, accessible, and affordable therapeutic option.

3. PRIMARY AND SECONDARY MEASURABLE OBJECTIVES

3.1 Primary Objectives

  1. To evaluate the effect of Nayanamrut Lauham on Best Corrected Visual Acuity (BCVA) in patients of Drushtipatalgata Vyadhi / AMD, as measured by Snellen's Visual Acuity Chart, before and after treatment.
  2. To assess the effect of Nayanamrut Lauham on central visual field defects in AMD patients, as evaluated by Amsler Grid testing and/or automated perimetry.
  3. To evaluate the effect of treatment on fundus findings (drusen size, RPE changes, neovascular activity) as documented by indirect ophthalmoscopy and fundus photography/OCT.

3.2 Secondary Objectives

  1. To assess the overall symptomatic improvement in patients, including reduction in metamorphopsia, blurring of central vision, and scotoma, using a validated symptom scoring scale.
  2. To evaluate the effect of Nayanamrut Lauham on contrast sensitivity and color vision (Ishihara chart) as measures of macular function.
  3. To assess the safety and tolerability of Nayanamrut Lauham over the treatment period through clinical monitoring and relevant biochemical investigations (CBC, LFT, RFT).
  4. To evaluate the Ayurvedic Dosha assessment (Vata-Pitta dominance) before and after treatment and correlate it with clinical outcomes.
  5. To document the overall quality of life improvement in patients using a visual function questionnaire (VFQ-25 or NEI-VFQ).
  6. To assess the rate of disease progression (conversion from dry to wet AMD, increase in drusen load) during the study period compared to natural history data.

4. RESEARCH QUESTIONS

  1. Does oral administration of Nayanamrut Lauham produce a statistically significant improvement in Best Corrected Visual Acuity (BCVA) in patients of Drushtipatalgata Vyadhi / AMD compared to baseline?
  2. Does Nayanamrut Lauham reduce or stabilize central visual field defects (as assessed by Amsler Grid and automated perimetry) in AMD patients over the course of treatment?
  3. What is the effect of Nayanamrut Lauham on fundus parameters — including drusen morphology, RPE integrity, and macular thickness on OCT — in patients of AMD?
  4. Is Nayanamrut Lauham safe and well-tolerated in the study population, with no significant adverse effects on hepatic, renal, or hematological parameters?
  5. Is there a correlation between the Ayurvedic Prakriti/Dosha profile of AMD patients and the degree of clinical response to Nayanamrut Lauham?
  6. Does Nayanamrut Lauham improve patient-reported visual quality of life outcomes (VFQ-25) in Drushtipatalgata Vyadhi patients?

5. HYPOTHESIS

5.1 Null Hypothesis (H₀)

Nayanamrut Lauham has no statistically significant effect on Best Corrected Visual Acuity (BCVA), central visual field, fundus parameters, or quality of life in patients of Drushtipatalgata Vyadhi with reference to Age-Related Macular Degeneration.

5.2 Alternate Hypothesis (H₁)

Nayanamrut Lauham has a statistically significant beneficial effect on Best Corrected Visual Acuity (BCVA), central visual field, fundus parameters, and quality of life in patients of Drushtipatalgata Vyadhi with reference to Age-Related Macular Degeneration.

5.3 Safety Hypothesis (H₀ Safety)

Nayanamrut Lauham will not produce significant adverse effects on hepatic, renal, or hematological parameters over the course of the study.
