A woman in her 20s presented with decreased vision in both eyes since childhood. Best-corrected visual acuity was 20/300 OD and 20/60 OS. Fundi in both eyes had changes of the retinal pigment epithelium with subretinal gliosis.1 The right eye had a full-thickness macular hole with subretinal fluid (Figure). Fluorescein angiography revealed hyperfluorescent and hypofluorescent areas that corresponded to retinal pigment epithelium changes in both eyes. Electroretinography revealed a subnormal scotopic and photopic response, an extinct rod photoreceptor response, and hypersensitivity to shorter wavelengths. A diagnosis of enhanced S-cone syndrome was made based on electroretinographic and clinical findings. The results of an NR2E3 mutation test were negative.

Retinal pigmentary changes and the amount of cystoid changes in the macula progress over time.1 In our patient, chronic schisis or subretinal fluid since childhood may have led to a previously undescribed full-thickness macular hole in this condition.2
