![]() Both are characterized by abnormal foveal contour and autofluorescence signal.Ībnormal foveal contour Epiretinal membrane Fundus autofluorescence Lamellar hole-associated epiretinal proliferation Optical coherence tomography. ![]() The eye contains a retina, which is a layer of tissue in the back of the eye that. Two types of FATIAS may be appreciated with SD-OCT and B-FAF analyses, the step and the rail type. Cystoid macular edema is when fluid builds up in a part of the eye called the macula, distorting the vision. We describe a distinct VMID named FATIAS. These include full-thickness macular hole (FTMH), foveal pseudocyst, lamellar macular hole (LMH) and macular pseudohole (MPH). Stage 2 MH is defined by a full thickness break < 400m in size. The depression in the very center of the macula where eyesight is sharpest. A stage 1B is a foveal detachment characterized by a lipofuscin-colored ring. A stage 1A is a foveolar detachment characterized a loss of the foveal contour and a lipofuscin-colored spot. LogMAR BCVA was 0.09 ± 0.1 and 0.1 ± 0.1 (P = 0.91), and CFT was 197.8 ± 9.7 and 202.2 ± 13.2 (P = 0.19) in the step and in the rail group, respectively. There is a wide spectrum of macular conditions that are characterized by an irregular foveal contour caused by a break in the inner fovea. Stage 1 MH, or impending MH, demonstrates a loss of the foveal depression. Both types presented with an area of increased B-FAF signal, usually bilobed in the step type and round and centered on the foveal pit in the rail type. The outer retinal bands were continuous in all cases. The following two types of FATIAS were identified: (1) the step type characterized by an asymmetric contour of the foveal pit and by a tissue of medium reflectivity on the foveal surface and (2) the rail type characterized by a shallow foveal pit and a rail of tissue of medium reflectivity on the foveal surface. Distinguishing features of FATIAS are an abnormal foveal contour either in the form of a step or in the form of a shallow foveal pit and reduced foveal. ![]() Main outcome measures were morphologic characteristics of the lesions, logarithm of minimum angle of resolution (logMAR) best-corrected visual acuity (BCVA), and central foveal thickness (CFT). The included eyes must present an irregular foveal contour on optical coherence tomography (OCT) and a pathologically increased autofluorescent signal at the fovea on blue-light fundus autofluorescence (B-FAF). Optical coherence tomography (OCT) is the gold-standard imaging modality for monitoring the posterior segment and a technique that residents will encounter early on in their training. To describe a distinct vitreomacular interface disorder (VMID) termed Foveal Abnormality associated with epiretinal Tissue of medium reflectivity and Increased blue-light fundus Autofluorescence Signal (FATIAS).Ī case series including forty-seven eyes of 47 patients.
