Effectiveness of vitrectomy in Terson syndrome — case series

Abstract

The visual outcomes of vitrectomy in a series of five eyes of three patients with vitreous haemorrhage due to Terson syndrome were retrospectively evaluated. There were two bilateral cases and one unilateral. The neurological diagnosis included cranio-cerebral trauma and cerebral aneurysm rupture. The mean time interval between intracranial haemorrhage and vitrectomy was nine months (range 7–10 months). Pars plana vitrectomy was performed with BSS as a tamponade in three eyes, SF6 gas in one eye, and silicone oil in one eye. The mean follow-up period was 12 months (range 1–27 months). Visual acuity improved significantly in all patients from counting fingers to the mean value of 0.6 (range 0.1–1.0). We observed one epiretinal membrane, one tractional retinal detachment, and two cataract formations. The best visual outcomes were achieved with BSS as a tamponade, the worst was with silicone oil as a tamponade and retinal detachment. Performing vitrectomy with BSS as a tamponade in patients with Terson syndrome significantly improves visual acuity, so early diagnosis and surgical treatment are crucial.
