Abstract

Abstract: : Purpose: To describe the optical coherence tomographic findings of the fovea in patients with history of previous phototoxic exposure. Methods: A case series. Results: Three patients with photic maculopathy were studied with Optical Coherence Tomography (OCT). One patient was affected by ultrashort-pulse laser reflected from a mirror, one had history of arc welding and one was a photographer who used to photograph sunsets. An outer lamellar hole was detected in each patient and the lesion was bilateral in one patient. No changes in the retinal thickness were noted. Conclusions: The lesions of solar retinopathy and laser burns are thought to share similar histopathological changes. An outer lamelar cystic change is believed to be produced by the thermally enhanced phototoxic reaction at the photoreceptor level and surface of the retinal pigmente epithelium. As the size is often small, the manisfestations are difficult to see clinically and often hard to document with fundus photograph. Imaging with fluorescein or indocyanine green angiography is not useful since the retinal pigment epithelium in the foveal area is more pigmented than elsewhere in the fundus, reducing light transmission from the choroid. OCT is a useful imaging technique for photic maculopathy. No other maculopathy is known to produce this localized, solitary outer retinal cystic change. Because of the improvement resolution and image quality, OCT-3 imaging is preferred than OCT-2.
