Newer surgical techniques for repair of giant retinal tears are yielding good anatomical and visual results, according to a retrospective study.

A.K. Tyagi, MS, FRCS, and colleagues at the Birmingham & Midland Eye Center, England, analyzed the case notes for 24 men and 5 women treated for giant retinal tears between 1991 and 2002, with follow-up ranging from 5 months to 7 years.

Among the 29 cases, 25 eyes developed retinal detachments with macular involvement; 10 of these eyes had greater than 6 D of myopia, according to the study.

All eyes underwent vitrectomy, the study authors said. Twenty-three eyes were treated using heavy liquids, and 16 eyes underwent scleral explants. A silicone oil tamponade was used in 28 eyes and C3F8 was used in one eye. Six eyes required multiple surgeries because of recurrent retinal detachments. Fellow eyes were prophylactically treated in 18 patients, according to the study.

At final follow-up, anatomically attached retinas were present in 25 patients, visual acuity had improved in 20 eyes, and three patients had total retinal detachment with marked proliferative vitreoretinopathy, the authors said.

The study is published in the journal Eye.
