In Vision 2020, Ophthalmic personnel per population ratio is:
**Core Concept**
The Vision 2020 initiative aims to eliminate avoidable blindness by the year 2020. A crucial aspect of this program is the establishment of an adequate ophthalmic workforce, which includes the personnel per population ratio. This ratio is essential for ensuring accessibility and quality of eye care services, particularly in resource-constrained settings.
**Why the Correct Answer is Right**
The World Health Organization recommends a minimum of one ophthalmologist per 50,000 population in developing countries. This ratio is crucial for ensuring that communities have access to basic eye care services, including cataract surgery, glaucoma management, and diabetic retinopathy screening. The ophthalmic personnel per population ratio is a key indicator of the adequacy of the eye care workforce, and it has significant implications for the prevention and treatment of avoidable blindness.
**Why Each Wrong Option is Incorrect**
* **Option A:** This option is incorrect because the recommended ratio of ophthalmologists per population varies depending on the country's income classification and the availability of resources. A one-size-fits-all approach may not be appropriate for different settings.
* **Option B:** This option is incorrect because it does not take into account the varying levels of ophthalmic personnel, including ophthalmologists, optometrists, and ophthalmic nurses. A more nuanced approach is required to determine the optimal ratio of personnel per population.
* **Option C:** This option is incorrect because it does not provide a specific ratio, making it difficult to assess its validity. A clear and specific ratio is necessary for determining the adequacy of the ophthalmic workforce.
**Clinical Pearl / High-Yield Fact**
The ophthalmic personnel per population ratio is a critical indicator of the accessibility and quality of eye care services. A minimum of one ophthalmologist per 50,000 population is recommended in developing countries to ensure that communities have access to basic eye care services.
**Correct Answer:** C. 1:50,000
