Analysis of the macula with optical coherence tomography after successful surgery for proliferative vitreoretinopathy.

Abstract

OBJECTIVE:

To use optical coherence tomography to assess the in vivo pathologic findings associated with incomplete visual recovery in patients who have undergone anatomically successful surgery to treat proliferative vitreoretinopathy.

METHODS:

Eligible patients were recruited in vitreoretinal outpatient clinics between April 1, 2002, and July 31, 2003. Patients were included who had undergone anatomically successful vitreoretinal surgery to treat proliferative vitreoretinopathy and, at least 3 months after surgery, had postoperative vision worse than expected (< or =6/12) with no identifiable cause at clinical examination. Patients underwent optical coherence tomography, stereo fundus fluorescein angiography was performed in a cohort of patients, and angiographic findings were compared with those on the optical coherence tomograms. Relevant clinical data were collected retrospectively from patient case notes.

RESULTS:

A total of 35 patients were recruited. Optical coherence tomograms revealed cystoid macular edema in 23 patients (66%) but did not identify any other specific intraretinal disease. Location of edema (outer or inner retina), determined with stereo fundus fluorescein angiography and optical coherence tomography, correlated well.

CONCLUSIONS:

Optical coherence tomography is a useful diagnostic tool for assessing poor postoperative visual acuity and can reveal disease undetected at clinical examination. Cystoid macular edema is a common finding on optical coherence tomograms in eyes with incomplete visual recovery after anatomically successful surgery to treat proliferative vitreoretinopathy.
