Abstract: :
Purpose: To use optical coherence tomography (OCT) for evaluation of clinical "yellow macula". Methods: Cross-sectional tomograms of the foveo-macular area were obtained using the Humphrey OCT 2000 scanner by conventional noninvasive, noncontact, low-coherence interferometry in four male patients with nearly normal visual acuity and varying degrees of "yellow macula". The mean age of the patients was 70.5 years. Epiretinal membranes were noted in two patients, with no leakage on fluorescein angiography. Another two patients had evidence of dry, age-related macular degeneration with no chorioretinal neovascularization on fluorescein angiography. Electro-oculograms (EOG) were normal in all patients. Results: OCT revealed a highly reflective dome-shaped fusiform thickening, the nature of which is unclear at the level of the retinal pigment epithelium-choriocapillaris. There was no loss of foveal depression, and no evidence of intraretinal edema. Conclusion: In patients with clinical "yellow macula", OCT may be useful for evaluating the presence of any abnormality in the foveo-macular area.
