Full-thickness eye-wall biopsy: long-term results in 9 patients.

Nine patients who had an eye-wall biopsy were evaluated for long-term results. The follow-up time ranged from 2 1/2 months to 7 years. Six patients were followed up for more than 2 years. Few operative and postoperative complications were observed. Except for 1 patient with reticulum cell sarcoma, all eyes retained preoperative visual acuity. Tractional retinal detachment occurred only in 1 patient, who had vitreous bands around the biopsy site and did not undergo a simultaneous vitrectomy during the biopsy operation.
