Fundus autofluorescence in cone dystrophy.
OBJECTIVE
To describe fundus autofluorescence (FAF) finding in a case of cone dystrophy.


METHODS
Interventional case report.


RESULTS
A 23-year-old woman presented with increasing photophobia and decreasing vision in both eyes for 2 years. Fundus examination showed several drusen-like dots. FAF revealed hyper-autofluorescence in the foveola. Electroretinogram (ERG) demonstrated a pure "cone" dystrophy.


CONCLUSIONS
Hyper-autofluorescence in the foveola is a non-specific manifestation of photoreceptor-retinal pigment epithelium dysfunction. ERG studies are essential for accurate diagnosis.
