I now have comprehensive information from the textbook and web sources. Let me compile the full, detailed answer.
National Programme for Control of Blindness and Visual Impairment (NPCB&VI)
1. Background and Launch
The National Programme for Control of Blindness (NPCB) was launched in 1976 as a 100% centrally sponsored programme. It incorporated the earlier Trachoma Control Programme started in 1968. The programme's name was later changed to "National Programme for Control of Blindness and Visual Impairment (NPCB&VI)" to align with a revised, WHO-consistent definition of blindness (inability to count fingers at 3 metres, changed from the earlier 6 metres standard adopted in 1976).
Currently it operates as a centrally sponsored scheme with a funding ratio of:
- 60:40 (Centre : State) for all states
- 90:10 for North-Eastern states (including Sikkim)
2. Goal
To reduce the prevalence of blindness from 1.4% to 0.3% (later revised target: 0.3% by 2020).
- Rapid National Survey 2006-07: prevalence = 1.0%
- National Survey on Blindness 2015-19: prevalence = 0.36% (down significantly, but target not yet fully met)
3. Causes of Blindness in India (2015-19 National Survey)
| Cause | % of Blindness |
|---|
| Cataract (untreated) | 66.2% |
| Non-trachomatous corneal opacity | 7.4% |
| Cataract surgical complications | 7.2% |
| Glaucoma | 5.5% |
| Other posterior segment disease | 5.9% |
| Phthisis | 2.8% |
| Diabetic retinopathy | 1.2% |
| Aphakia uncorrected | 1.7% |
| ARMD | 0.7% |
| Trachomatous corneal opacity | 0.8% |
| Refractive error | 0.1% |
Key facts on epidemiological determinants:
- Age: ~30% of the blind in India lose sight before age 20; senile cataract occurs a decade earlier in India compared to Europe/America
- Sex: Higher prevalence in females (higher trachoma, conjunctivitis, and cataract rates)
- Malnutrition: Vitamin A deficiency (keratomalacia) is a major preventable cause, especially in children aged 6 months to 3 years
- Occupation: Factory and cottage industry workers are at high risk for eye injuries
- Social class: Blindness is twice as prevalent among lower socioeconomic groups
- Retinopathy of Prematurity (ROP): An emerging cause in children, with increased survival of premature babies in NICUs
4. Objectives (12th Five Year Plan Period)
- Three signature activities:
- 66 lakh cataract operations per year
- School eye screening + distribution of 9 lakh free spectacles/year to children with refractive errors
- Collection of 50,000 donated eyes/year for keratoplasty
-
Reduce the backlog of avoidable blindness through identification and treatment at primary, secondary, and tertiary levels
-
Develop "Eye Health for All" strategy - universal, comprehensive eye-care services
-
Strengthen and upgrade Regional Institutes of Ophthalmology (RIOs) as centres of excellence in ophthalmology sub-specialties
-
Strengthen infrastructure and human resources for high-quality eye care in all districts
-
Enhance community awareness on eye care and preventive measures
-
Expand research for prevention of blindness and visual impairment
-
Secure participation of voluntary organizations and private practitioners
5. Strategies / Salient Features
- Continued free cataract surgery through the health system, NGO sector, and private practitioners
- Comprehensive eye care beyond cataract: diabetic retinopathy, glaucoma, corneal transplantation, vitreo-retinal surgery, childhood blindness
- Active population screening above 50 years, organizing eye camps and transporting operable cases to fixed facilities
- Refractive error screening in children + free glasses for those below the poverty line
- Coverage of underserved areas through public-private partnership
- Capacity building of health personnel
- IEC (Information, Education, Communication) activities for community awareness
- Strengthening Regional Institutes of Ophthalmology and Medical Colleges
- Upgrading district hospitals with infrastructure, equipment, and contractual manpower
- Establishing Vision Centres at all PHCs with a Paramedical Ophthalmic Assistant (PMOA)
- Multipurpose District Mobile Ophthalmic Units for better rural/remote coverage
6. Organizational / Administrative Structure
| Level | Body |
|---|
| Central | Ophthalmology Section, Directorate General of Health Services, MoH&FW, New Delhi |
| State | State Ophthalmic Cell / State Blindness Control Society (merged with State Health Society under NHM) |
| District | District Blindness Control Society (merged with District Health Society) |
7. Service Delivery and Referral System
| Level | Facilities |
|---|
| Tertiary | Regional Institutes of Ophthalmology (RIOs), Centres of Excellence, Medical Colleges |
| Secondary | District Hospitals, NGO Eye Hospitals |
| Primary | Sub-district hospitals/CHCs, Mobile Ophthalmic Units, Upgraded PHCs, Link Workers/Panchayats |
- 80 central mobile units attached to medical colleges
- 341 district mobile units providing eye care through mobile eye camps
- Intra-ocular lens (IOL) implantation facilities expanded to taluka level
8. Key Components
A. Cataract Surgery
The most important intervention. Since 2019-20, the programme has consistently exceeded its annual targets:
- 2022-23: 8.73 lakh surgeries (112.5% of target)
- 2023-24: 9.45 lakh surgeries (101.5% of target)
- IOL implantation rate consistently ~99% of all cataract surgeries
B. School Eye Screening Programme
- 6-7% of children aged 10-14 have vision problems affecting learning
- Children first screened by trained teachers; those suspected of refractive error referred to ophthalmic assistants
- Free spectacles provided to children below the poverty line
- Achievement 2023-24: ~12 lakh free spectacles distributed
C. Eye Donation and Keratoplasty
- Target: 50,000 donated eyes/year
- 2018-19 achievement: 68,409 donated eyes collected
- Hospital retrieval programme is the primary strategy - motivating relatives of terminally ill patients and accident victims
- Eye Donation Fortnight: 25th August to 8th September each year
- Leading states: Gujarat, Tamil Nadu, Maharashtra, Andhra Pradesh
- Indigenous cornea storage media developed under NPCB&VI
D. Management of Other Eye Diseases
- Diabetic retinopathy (laser + medical treatment)
- Glaucoma (surgical + medical)
- Retinopathy of Prematurity (ROP) with laser treatment
- Retinoblastoma surgery
- Congenital ptosis surgery
- Intraocular trauma in children
- Vitreo-retinal surgery
9. Role of Primary Health Worker (MPW/ASHA) in NPCB
Under the national programme, the primary health worker is responsible for:
- Identifying and referring all cases of blindness, including suspected cataracts, to the MO at PHC
10. Special Provisions for NE States / Tribal Areas
- Construction of dedicated eye units in North-Eastern states and hilly states
- Appointment of contractual ophthalmic manpower (surgeons, assistants, eye donation counsellors)
- Multipurpose District Mobile Ophthalmic Units for remote/difficult areas
- In 2025, 3 new multipurpose district mobile ophthalmic units established
11. Vision 2020: The Right to Sight
A global WHO initiative to eliminate avoidable blindness by 2020; India is committed to it. The plan features a four-tier structure:
| Tier | Number | Type |
|---|
| Centres of Excellence | 20 | Advanced subspecialty care |
| Training Centres | 200 | Ophthalmology training |
| Service Centres | 2,000 | Secondary care |
| Vision Centres | 20,000 | Primary/community eye care |
Target diseases: Cataract, refractive errors, childhood blindness, corneal blindness, glaucoma, diabetic retinopathy.
12. Role of NGOs and Voluntary Organizations
- 2,038 NGOs and 748 private practitioners registered under NPCB&VI MIS dashboard
- Organizations like Lions International, Rotary International, and NSPB India actively organize eye camps
- Voluntary organizations provide: health education, preventive services, rehabilitative services, surgical services
