Serous central chorioretinopathy. Acute autofluorescence of the pigment epithelium of the eye

PURPOSE: The lack of histopathological material has placed limitations on our knowledge on lipofuscin in central serous chorioretinopathy (CSCR). This study was designed to document the pathological changes of the retinal pigment epithelium (RPE) in CSCR using in vivo recording of fundus autofluorescence. METHODS: Fundus autofluorescence was documented in 62 eyes of 44 subjects with CSCR using a laser scanning ophthalmoscope (Zeiss, Oberkochen; excitation wavelength: 488 nm, barrier filter at 521 nm). Images were compared to the respective fundus appearance and fluorescein angiograms. RESULTS: Neurososensory retinal detachments showed diffuse increased autofluorescence corresponding to the detached area. Long-standing lesions showed very irregular autofluorescence with regions greater and less than the background levels of autofluorescence. CONCLUSION: Focal accumulation of autofluorescent material occurs at the level of the RPE in patients with CSCR, relating to variation in metabolic activity of the RPE. This technique may be useful in selecting patients for laser photocoagulation.
