A 40 year old male has vision of 6/60 in right eye and 3/60 in left eye under NPCB, he will be classified as:-
**Core Concept**
The NPCB (National Programme for Control of Blindness) classification system is used to categorize patients with vision impairment. It is based on the visual acuity of each eye, with a distinction between unilateral and bilateral vision loss.
**Why the Correct Answer is Right**
To classify a patient under the NPCB system, we need to determine the better eye vision. In this case, the patient's better eye vision is 3/60, which is considered 'low vision'. A patient is classified as having low vision if their visual acuity is between 6/18 and 3/60 in the better eye. However, if the visual acuity is worse than 3/60 in the better eye, the patient is classified as 'blind'. Since the patient's better eye vision is 3/60, he meets the criteria for low vision.
**Why Each Wrong Option is Incorrect**
* **Option A:** This option is not relevant to the NPCB classification system.
* **Option B:** This option is incorrect because it does not accurately describe the classification of a patient with a better eye vision of 3/60.
* **Option C:** This option is incorrect because it does not accurately describe the classification of a patient with a better eye vision of 3/60.
**Clinical Pearl / High-Yield Fact**
It's essential to note that the NPCB classification system is used to prioritize patients for cataract surgery and other eye care services. Patients with low vision are generally considered for treatment, while those with severe vision loss (blindness) may require more intensive rehabilitation.
**Correct Answer:** C.
