Preoperative spectral-domain optical coherence tomography in patients having cataract surgery

Abstract

To evaluate the role and cost-effectiveness of preoperative spectral-domain optical coherence tomography (SD-OCT) in patients having cataract surgery. Fondation Opthalmologique Adolphe de Rothschild, Paris, France. Retrospective case series. All patients who had cataract surgery had macular and retinal nerve fiber layer SD-OCT preoperatively. A complete ophthalmologic examination was performed, including corrected near (CNVA) and corrected distance visual acuities, intraocular pressure (IOP), and a fundus examination. The study comprised 245 patients (401 eyes) with amean age of 73.5years±9.81 and a mean IOP of 15.6±3.04mm Hg. Of 107 eyes (26.7%) with abnormal macular SD-OCT, 70 eyes were judged normal on fundus examination. The most frequent anomalies were age-related macular degeneration and epiretinal membrane. Age over 70years and CNVA worse than Parinaud 2 were associated with higher rate of abnormal macular SD-OCT (odds ratio, 2.76 and 2.28, respectively). Fifty-seven eyes (14.2%) had abnormal retinal nerve fiber layer SD-OCT, 30% of them with no history of glaucoma and no detected anomaly on fundus examination. Age over 70years and a history of glaucoma were associated with a higher rate of retinal nerve fiber layer anomalies. Preoperative SD-OCT scanning was significantly more effective in detecting anomalies in patients having cataract surgery than fundus examination. Older age and CNVA worse than Parinaud 2 were associated with higher rates of abnormal macular SD-OCT. Older age and a history of glaucoma were associated with higher abnormal retinal nerve fiber layer anomaly rates.
