Title: Effect of central retinal artery occlusion on retinal microstructure of macula in vivo
Abstract: AIM: To investigate the effect of ischemia induced by central retinal artery occlusion on retinal microstructure of macula using optical coherence tomography (OCT). METHODS: Fourteen eyes of 14 patients with unilateral central retinal artery occlusion (CRAO) in two to three days without fully recovery of retinal circulation underwent OCT examination with 4.5 mm length horizontal and vertical line scans through foveola to measure the retinal neurosensory layer (RNL) thickness on foveola, 175 μm (fovea), 750 μm (macula) to foveola, respectively. The other normal eyes of patients as control group underwent the same examination and measurement. RESULTS: The mean RNL thickness(μm) on foveola, fovea, macula were 169 91±10 96, 176 36±11 74 and 256 45±16 95 respectively in normal control eyes, and 235 64±47 02 , 241 84±49 36 and 401 57±54 53 respectively in CRAO eyes with retinal ischemia. There was a significant difference in thickness between two group ( P0.05, P 0.01). CONCLUSION: Retinal microstructure of macula significantly changed in ischemia eyes with CRAO.
