Purpose: To evaluate long-term clinical outcomes of patients with central retinal artery occlusion and to investigate factors associated with visual recovery.
Methods: This retrospective study was performed on 31 patients with central retinal artery occlusion. The patients were divided into 3 groups according to degree of vascular occlusion: incomplete, subtotal, total. Visual acuity was classified as finger counting or worse, 0.02 or better and worse than 0.1, and 0.1 or better. The proportions of patients in these 3 groups at diagnosis were compared to those at the final follow-up. In addition, factors associated with visual recovery were investigated.
Results: The mean follow-up period was 40.0 ± 22.0 months. According to degree of vascular occlusion, 10 patients were incomplete, 17 were subtotal, and 4 were total. During the follow-up period, visual acuity was recovered in 14 patients, maintained in 6, and deteriorated in 11. At diagnosis, visual acuity was finger counting or worse in 77.4% of patients, 0.02 or better and worse than 0.1 in 22.6%, and 0.1 or better in 0. At the final visit, these proportions changed to 58.1%, 22.6%, and 19.4% (p = 0.013), respectively. Visual recovery was limited with greater degree of occlusion (p = 0.004).
Conclusions: During the follow-up period, visual recovery was noted in 45% of patients with central retinal artery occlusion. Degree of vascular occlusion was identified as a factor predictive of visual recovery.
