Abstract

Abstract : Purpose: To analyze the multimodal imaging features in a case showing resolution of retinal pigment epithelium (RPE) apertures in association with an avascular pigment epithelium detachment secondary to nonneovascular age-related macular degeneration. Methods: Report of a case diagnosed with aperture of the RPE with multimodal imaging long-term follow-up. Color fundus photography, fundus autofluorescence, eye-tracked spectral domain optical coherence tomography (OCT), and OCT angiography findings are discussed. Results: A 71-year-old man diagnosed with nonneovascular age-related macular degeneration presented with three different areas of RPE aperture in his right eye. At baseline, best-corrected visual acuity was 20/100 in his right eye. Dilated fundus examination showed three round areas of RPE atrophy, and fundus autofluorescence demonstrated marked hypoautofluorescence in the corresponding areas. The OCT scans showed discontinuities of the RPE band with no evidence of RPE tear. The OCT angiography showed no evidence of abnormal blood flow within the sub-RPE space. Over time, fundus autofluorescence and eye-tracked spectral domain OCT scans demonstrated spontaneous resolution of two of the RPE defects and reduction of the size of the third one, with complete flattening of the pigment epithelium detachment. Conclusion: Distinction between RPE tears and apertures is important due to their different etiopathogenic mechanism and prognosis. To the best of our knowledge, this is the first report of a case of complete closure of an RPE aperture. The mechanism of the observed RPE closure remains unknown, and further studies are warranted to better understand the mechanisms of RPE restoration and remodeling. Abstract : We present an unusual case of retinal pigment epithelium apertures in the presence of a serous pigment epithelium detachment with progressive resolution of the defects and flattening of the detachment.
