Overview

Reticular dystrophy is characterised by a clearly defined network of hyperpigmented lines that resemble a knotted fishing net.

Case Example

Case 1

A 22-year-old Caucasian female with visual acuity of 6/6 (20/20) in each eye.

OCT shows focal RPE elevations corresponding to the reticular lines. Subfoveal line scan shows subretinal hyper-reflective materials.
