Definition of Blindness:
- NPCB: Inability to count fingers from 6 meters (vision ≤
6/60).
- WHO: Vision ≤ 3/60.
Major Causes of Blindness:
- Cataract (62%)
- Refractive Errors (20%)
- Glaucoma (6%)
- Posterior Segment Disorders (5%)
- Post Capsular Opacification, Corneal Blindness,
Surgical Complications (1% each)
- Others (4%)
Types of Blindness:
- Economic: Vision ≤ 6/60.
- Social: Vision ≤ 3/60 or visual field ≤ 10°.
- Absolute: No light perception.
- Manifest: Vision 1/60 to light perception.
- Curable: Reversible with treatment (e.g., cataract).
- Preventable: Avoidable with preventive care (e.g., xerophthalmia).
- Avoidable: Includes both preventable and curable blindness.
Introduction:
- Launched in 1976 as the world's
first national-level blindness control programme.
- Goal: Reduce blindness prevalence from 1.4% to 0.3%.
- Progress: Reduced to 1.1% in 2001-02 and 1.0%
in 2006-07.
- Decentralized in 1994-95 with the formation of District
Blindness Control Societies (DBCS).
- Aligns with Vision 2020: The Right to Sight.
Visual
Acuity:
- Defined as the sharpness of vision,
measured by comparing what a person can see to what a person with normal
vision can see.
Objectives:
1.
Identify and treat blindness at all
levels (primary to tertiary).
2.
Strengthen eye care services and
deliver quality care.
3.
Upgrade Regional Institutes of
Ophthalmology (RIOS).
4.
Improve infrastructure and human
resources.
5.
Raise community awareness on eye
health.
6.
Promote research in blindness
prevention.
7.
Involve NGOs and private
practitioners.
Strategies:
- Focus on free cataract surgeries
through public and private sectors.
- Expand scope to include other conditions:
Diabetic Retinopathy, Glaucoma, Corneal Blindness, Vitreo-retinal diseases, Childhood Blindness, etc.
Key
Initiatives & Activities:
·
Active
Screening: Focus on screening
people over 50 years for cataract to reduce
backlog.
·
Capacity
Building: Train eye care
providers and upgrade infrastructure.
·
IEC
Activities: Awareness programs
on eye care for the community.
·
Strengthening
Institutions: Upgrade RIOS,
medical colleges, and district hospitals with equipment, staff, and
funds.
·
Primary
Eye Care: Establish Vision
Centers at PHCs and strengthen primary eye services.
·
Mobile
Ophthalmic Units (MDMOU):
- Screen patients in remote areas
- Transport patients to hospitals
- Conduct on-spot refraction & provide free glasses
- Detect conditions like diabetic retinopathy
& glaucoma
- Display health messages & involve local governance
·
School
Eye Screening: Identify and
treat refractive errors in primary and secondary
school children, with focus on underserved areas.
·
Community
Focus: Special emphasis on illiterate
rural women, integrating with women & child development schemes.
·
Dedicated
Facilities: Build Eye
Wards and Eye OTs in district hospitals as needed.
·
Private
Sector Involvement: Encourage
participation of private practitioners and NGOs.
Components of NPCB:
1.
Cataract surgery – Core focus of the program.
2.
Eye screening – For early detection of visual impairments.
3.
Eye donation – Promoted through Eye Donation Fortnight (Aug
25–Sep 8).
4.
Voluntary organization participation – NGOs support eye care services.
5.
Vitamin A prophylaxis – Oral syrup for all preschool children.
6.
IEC Activities – Awareness programs like World Sight Day
(2nd Thursday of October).
Integrated Initiatives:
- Free cataract surgeries, medicines, and spectacles
(for postoperative care and poor students).
- Free transport for patients from
remote areas.
- Coverage of all school children for
screening and Vitamin A & immunization.
- Establishment of Eye Banks and one Regional
Institute of Ophthalmology (RIO).
- Modern eye care services at Medical Colleges
& District Hospitals (DHHs).
Outcomes & Achievements:
- IOL
(Intraocular Lens) surgeries
rose from 20% (1997–98) to 95% (2013–14).
- 15.3
million cataract surgeries
conducted, preventing blindness.
- 70–80% of targeted school children
receive free spectacles yearly.
- Increased eye donation due to
awareness campaigns.
- Free treatment provided for diabetic
retinopathy, glaucoma, childhood blindness, keratoplasty, etc.
