Photoreceptor layer feature in eye with cloed macular hole: Optical coherence tomography finding and correlation with viual outcome

Purpoe tudy correlation between optical coherence tomography (OCT) finding and viual acuity (VA) outcome after ucceful macular hole urgery (MH). Deign Retropective cro-ectional tudy. Method Potoperative OCT can were analyzed in 34 eye of 30 patient. Raw file of horizontal and vertical OCT can were exported to Adobe Photohop 7.0. Meaured parameter included central foveal thickne, photoreceptor thickne, photoreceptor reflectivity, and relative reflectivity of photoreceptor to retinal pigment epithelium in the foveal area. Foveal configuration wa ubjectively graded. Reult OCT can were obtained at a median of 2 year (1 month to 10 year) potoperatively. The median viual acuity wa 20/80 (20/50 to 8/200) preoperatively and 20/50 (20/20 to 5/200) potoperatively. The median foveal thickne wa 198.5 μ (148 to 283). The mean (D) photoreceptor layer thickne wa 16.5 (8) μ in the 500 μ area and 17.5 (8) μ in the 1000 μ area. Mean (D) of relative reflectivity of the photoreceptor layer wa 0.60 (0.10) in both 500 μ and 1000 μ area. Potoperative VA did not correlate with foveal thickne or foveal configuration. Central (500 μ and 1000 μ) photoreceptor thickne wa ignificantly correlated with final VA (r = .38, P = .026, each). Relative reflectivity of photoreceptor to retinal pigment epithelium in the 500 μ area wa correlated with potoperative VA at a borderline ignificance (r = .32, P = .07). Relative reflectivity of photoreceptor to retinal pigment epithelium in the 1000 μ area wa not ignificantly correlated with potoperative VA (r = .27, P = .12). Concluion pecific retinal feature can be aeed from OCT image. Morphology and thickne of the foveal photoreceptor layer correlate well with macular function after ucceful MH. Outer retinal feature appear to be more important to determine potoperative viual function. Inner retinal feature may be more relevant for the ophthalmocopic appearance of anatomic cloure.
