Multiple Choice

The fovea is approximately _____________ mm in diameter.

Explanation:
The fovea is a tiny central pit in the macula responsible for the sharpest vision, and its diameter is commonly cited as about 1.5 mm. This standard size comes from anatomical measurements and clinical imaging, making 1.5 mm the best match for the fovea’s typical span. While there can be slight individual variation, 1.5 mm is the reference diameter used in practice.
