Purpose
To present qualitative and quantitative changes in OCT image evolving during time in eyes with central retinal artery occlusion. Material and methods Results of OCT examination of 8 patients with central retinal artery occlusion were studied. The patients age ranged from 56 to 81 years (median – 63). The Group consisted of 5 men and 3 women. Follow-up period ranged from 6 o 28 months (median – 14 months). Patients were examined in acute stage of CRAO (1–3 days), 1, 3, 6, 9, 12 and 24 months after CRAO episode. The OCT examination was performed using Cirrus OCT (Zeiss) and macular region analyzed using a standard scanning protocol Macula Thickness: Macular Cube 512x128. Results In an acute stage of CRAO increased thickness and hyperreflectivity of the inner retinal layers with corresponding hyporeflectivity layer below was detected. During follow-up period thickness of inner retinal layers and total retinal thickness gradually decreased. The other retinal layers presented increased reflectivity over time. After 6 months of observation we observed an atrophy of the retinal layers and lack of fovea profile in all cases. Conclusions The SD-OCT examination appears to be a perfect method for the determination of the dynamics of the edematous and atrophic changes evolving after CRAO in the macular area. keywords:
