Inferior retinectomy can repair detachment with PVR

In some cases, inferior retinectomy can be a successful treatment option for patients with retinal detachment complicated by proliferative vitreoretinopathy, according to Christina R. Gonzales, MD.
She reviewed the records of patients who underwent vitrectomy surgery with inferior retinectomy and identified 56 patients who met a number of inclusion criteria. Patients had retinal detachments with proliferative vitreoretinopathy (PVR) or anterior PVR of more than one clock hour. The patients were treated over a 6-year period.
The primary outcome was retinal reattachment. Secondary outcomes were a change in visual acuity, average number of procedures to achieve reattachment, numbers of operations before retinectomy, radical base dissection and lensectomy, silicone oil tamponade, location and extent of retinectomy and incidence of postoperative complications. The mean follow-up was 25 months.
Reattachment was achieved in 52 patients (93%). Dr. Gonzales said vision was initially limited in patients after vitrectomy but stabilized in 39 (70%) patients.
Two factors were found to be independently associated with better anatomic outcomes. Patients who underwent radical anterior base dissection with lensectomy and those who had silicone oil tamponade had better anatomical outcomes.
Dr. Gonzales will discuss her findings from this study at Hawaii 2005, The Royal Hawaiian Eye Meeting, next week.
