A 35-year-old male patient with blurred vision in both eyes since childhood has been diagnosed with foveaschisis at the age of 14. The patient had 5 brothers, all reported to have similar retinal problems. His best-corrected visual acuity was 4/10 in both eyes. Fundus examination showed retinoschisis in the lower temporal quadrants in both eyes, pigmented laser scars in the same area in the right eye, and a dull foveal reflex was observed in both eyes. The foveal sections examined with high-resolution optical coherence tomography (OCT) demonstrated atrophy in the fovea bilaterally. OCT sections did not show any accumulation of intraretinal or subretinal fluid or any cystic cavities; yet, thinning was observed especially on the superficial retinal layers. Structures under the outer plexiform layer were observed as normal. Even though these OCT findings are not merely diagnostic as in early-stage familial foveal retinoschisis, there is no doubt that they still facilitate the diagnosis.
