PURPOSE-To examine choroidal thickness and area in healthy eyes using spectral domain optical coherence tomography (SD-OCT). DESIGN-Retrospective, observational case seriesMETHODS-Thirty-four eyes (34 subjects), with no retinal or choroidal disease, underwent high definition raster scanning using SD-OCT with frame enhancement software. Choroidal thickness was measured from the posterior edge of the retinal pigment epithelium to the choroid/sclera junction at 500 μm intervals up to 2500 μm temporal and nasal to the fovea. The central 1 mm area of the choroid was also measured, along with foveal thickness of the retina. All measurements were performed by two independent observers. Statistical analysis was used to correlate interobserver findings, choroidal thickness and area measurements with age, and choroidal thickness with retinal foveal thickness. RESULTS-The 34 subjects had a mean age of 51.1 years. Reliable measurements of choroidal thickness were obtainable in 74% of eyes examined. Choroidal thickness and area measurements had strong inter-observer correlation (r =0.92, P < 0.0001) and (r =0.93, P < 0.0001) respectively. Area had a moderate negative correlation with age (r =-0.62, P < 0.0001) that was comparable to the correlation between mean subfoveal choroidal thickness and age (r =-0.61, P < 0.0001). Retinal and choroidal thickness were found to be poorly correlated (r =-0.23, P = 0.18). Mean choroidal thickness showed a pattern of thinnest choroid nasally, thickening in the subfoveal region, and then thinning again temporally. Mean subfoveal choroidal thickness was found to be 272 μm (SD, +/-81 μm).CONCLUSIONS-Choroidal thickness can be measured using SD-OCT high definition raster scans in the majority of eyes. Choroidal thickness across the macula demonstrates a thin choroid nasally, thickest choroid sub-foveally, and again thinner temporally, and a trend toward decreasing choroidal thickness with age.

Background: Macular recovery after surgery for retinal detachment depends on pre-operative and post-operative predictive factors. Pre-operative factors, which influence macular recovery negatively, include duration of macular detachment, height of macular detachment and vitreomacular traction. Post-operative factors, which influence macular recovery negatively, include cystoid macular edema, epiretinal membranes, retinal folds, subretinal Retinal Pigment Epithelium (RPE) migration and persistent subretinal fluid.OCT has elucidated several postoperative factors correlating with poor vision. These features include persistent SRF and increased foveal thickness ,demonstrating as well the submacular fluid that couldn't be detected clinically. OCT can detect persistent foveal detachment, distortion and disruption of Outer Retinal Layers (ORLs) and macular folds following successful surgery for RD. FAF has been used to investigate the morphological and functional changes occurring after RD repair.Objective: The aim of our study is to correlate the structure-function relationship of the macula following successful repair of rhegmatogenous retinal detachment, by correlating the SD-OCT and FAF macular images with BCVA.
