ABSTRACT
PURPOSE:
This study investigated visual acuity (VA) values and differences depending on optical coherence tomography (OCT) findings in patients with acute central retinal artery occlusion (CRAO).METHODS:
A retrospective chart review was performed on patients with acute CRAO who underwent macular and disc OCT. We evaluated changes in macular thickness and retinal nerve fiber layer (RNFL) thickness after acute CRAO onset based on OCT. We also determined the association of thickness changes with VA improvement.RESULTS:
This study involved both eyes in a total of 12 patients with acute CRAO. A significant increase was observed in foveal (1 mm) thickness (p = 0.002), parafoveal (3 mm) thickness (p = 0.002), and peripapillary RNFL thickness (p = 0.005) in affected eyes with CRAO, but not in central foveal thickness (p = 0.266). A significant small difference in both eyes (affected eye – fellow eye) was shown in foveal (1 mm) and mean parafoveal (3 mm) thickness in the improved VA group (p = 0.008 and p = 0.004, respectively), but not in central foveal or peripapillary RNFL thickness (both p = 0.283).CONCLUSIONS:
Both macular and RNFL thickness increased in patients with acute CRAO. RNFL thickness decreased over time with progression of RNFL atrophy. Less macular damage caused by acute CRAO could be predicted by a small difference in macular thickness between eyes (affected eye – fellow eye). In such cases, patients had a greater chance of VA improvement.
