Abstract

Purpose: To investigate the correlation between the time of vitrectomy and visual prognosis and possible causes of vitreous hemorrhage in non-diabetic patients diagnosed with vitreous hemorrhage.
Methods: This study investigated the possible causes of vitreous hemorrhages based on the medical records of 97 eyes that underwent vitrectomy. Subjects were divided into early (within 6 weeks) and late (after 6 weeks) groups based on the time of surgery, and the best corrected visual acuity, visual acuity improvement, and the correlation between the time of surgery and the visual acuity were analyzed.
Results: There was no significant difference in average visual acuity before a vitrectomy, average visual acuity 1 year after the surgery, mean visual acuity improvement between the two groups when the underlying cause was branch retinal vein occlusion, retinal tear, or trauma (p＞0.05). However, when the underlying cause was central retinal vein occlusion, the mean visual acuity improvement was significantly higher in the early surgery group (p=0.005).
Conclusions: The timing of vitrectomy in non-diabetic patients with vitreous hemorrhages caused by diseases other than central retinal vein occlusion did not significantly increase the visual acuity. However, it is important to promote early visual recovery and find out underlying disease of vitreous hemorrhage by early vitrectomy in order to prevent complications.
