Abstract

PURPOSE
To determine the results of pars plana vitrectomy (PPV) for the treatment of severe giant retinal tear. METHODS: We analyzed the clinical records of patients who had 150degrees or greater of giant retinal tear and underwent PPV. RESULTS: Of all 10 patients (10 eyes), 7 were male patients and mean age was 29.8 years. Giant retinal tear was idiopathic in 6 eyes and traumatic in 1 eye, and occurred after vitrectomy in 3 eyes. Primary operations were scleral buckle in 1 eye, PPV with intraocular gas injection in 2 eyes and with silicone oil (SO) injection in 7 eyes. In 3 eyes without SO injection, secondary operations were PPV with intraocular gas injection in 1 eye and with SO injection in 2 eyes. In 1 eye with PPV and intraocular gas injection, tertiary operation was PPV with SO injection. Removal of SO was done in all 10 eyes and SO was re-injected due to proliferative vitreoretinopathy in 2 eyes. Visual acuity was counting fingers or worse in 8 eyes before the primary operation and, on the final visit, 0.1 or better in 6 eyes and 0.3 or better in 3 eyes. CONCLUSIONS: These results suggest that PPV with SO injection might be better for the treatment of severe giant retinal tear than with intraocular gas injection.
