Which of the following disease is not considered by NPCB for renumeration of surgery done by NGO eye hospital?
## Core Concept
The National Programme for Control of Blindness (NPCB) in India has guidelines for the remuneration of surgeries done by NGO eye hospitals. These guidelines typically cover specific eye conditions for which surgical interventions are reimbursed. The question pertains to the conditions for which surgical remuneration is not considered by NPCB.
## Why the Correct Answer is Right
Cataract surgery is a primary focus for NGOs and is often reimbursed or supported by governmental programs aiming to reduce blindness. Glaucoma and diabetic retinopathy surgeries are also significant and can be reimbursed under various health programs. However, **refractive errors** (option D), such as myopia, hyperopia, and astigmatism, are generally not considered for surgical reimbursement under NPCB guidelines for NGO eye hospitals, as these are often addressed through non-surgical means like glasses or contact lenses.
## Why Each Wrong Option is Incorrect
- **Option A:** Cataract is a leading cause of blindness worldwide and in India. Surgical intervention for cataracts is a key component of blindness control programs, including NPCB, making it eligible for remuneration.
- **Option B:** Glaucoma can lead to blindness if not treated. Surgical interventions for glaucoma are critical and are usually covered under health programs.
- **Option C:** Diabetic retinopathy is another major cause of blindness that can be addressed through surgical interventions like laser photocoagulation or vitrectomy, and such procedures are often supported.
## Clinical Pearl / High-Yield Fact
A significant clinical pearl is that **cataract surgery** is one of the most cost-effective interventions in ophthalmology and is frequently supported by governmental and non-governmental organizations to prevent blindness.
## Correct Answer: D. Refractive errors
