Fundus autofluorescence, optical coherence tomography, and electroretinogram findings in choroidal sclerosis.
OBJECTIVE
The purpose of this study was to describe fundus autofluorescence (FAF), optical coherence tomography, and electroretinogram findings in choroidal sclerosis.


METHODS
This is a retrospective case series. Eight eyes of four patients with choroidal sclerosis were evaluated with FAF, optical coherence tomography, and electroretinogram testing.


RESULTS
In all eight eyes, FAF imaging showed hypofluorescent placoid lesions corresponding to areas of chorioretinal atrophy seen on stereo biomicroscopy. Prominent hyperfluorescent linear markings underlying regions of atrophic disease were observed in all eyes, likely representative of normal choroidal vessel autofluorescence. In two eyes, FAF showed punctate hypofluorescent lesions in the fovea that were not visualized on biomicroscopy. In one eye, FAF identified a central island of preserved retinal pigment epithelium that was not realized on ophthalmoscopic examination. Optical coherence imaging was significant for loss of choroidal fine tubular structures, retinal pigment epithelium, and outer nuclear layer in regions of chorioretinal atrophy. Full-field electroretinogram testing showed generalized rod-cone dysfunction in all patients with a lower B- to A-wave ratio in two patients.


CONCLUSIONS
Fundus autofluorescence and optical coherence tomography are nonin-vasive diagnostic adjuncts that can aid in the diagnosis of choroidal sclerosis. Fundus autofluorescence may be a more sensitive marker of disease extent and progression than clinical examination alone. Electroretinogram testing can result in an electronegative maximal response.
