Patient management modifications in cataract surgery candidates following incorporation of routine preoperative macular optical coherence tomography

Purpose: To assess the clinical relevance of routine preoperative spectral-domain optical coherence tomography (SD-OCT) for identifying macular pathologies in patients scheduled for cataract surgery. Setting: Shaare-Zedek Medical Center, Jerusalem, Israel. Design: Retrospective case series. Methods: Consecutive patients, 50 years of age and older, scheduled for standard cataract extraction surgery were enrolled from November 2017 to January 2018. All study patients underwent routine SD-OCT scanning before cataract surgery. The scans were reviewed by a retinal specialist for macular pathology and compared with preoperative fundus biomicroscopic examination findings. The incidence of macular pathologies and changes in patient management as a result of the macular SD-OCT findings were assessed. Results: Four hundred fifty-three eyes of 453 patients were enrolled in the study; 42 eyes (9.2%) were excluded because of noninterpretable SD-OCT scans attributable to advanced cataract, leaving scans of 411 eyes of 411 patients for study inclusion. Macular pathologies were detected by SD-OCT in 167 eyes (40.6%), including age-related macular degeneration (50%), epiretinal membrane (28.3%), and cystoid macular edema (12.8%). Overall, the management of 107 patients (26.0%) was modified because of macular SD-OCT findings, which were either missed (22.8%) or underestimated (3.2%) by the fundus biomicroscopic examination. Changes in preoperative patient management included altering patient consultation regarding presbyopia correction solutions (73 eyes [17.8%]) and referral to a retinal specialist for consultation (34 eyes [8.3%]). Conclusions: Routine macular SD-OCT scans for cataract surgery candidates helped to identify macular pathologies that might be missed or underestimated by standard fundus bio-microscopic examination. The added information could improve patient management. Copyright (C) 2020 Published by Wolters Kluwer on behalf of ASCRS and ESCRS

Automated summary

This study assessed the clinical relevance of routine preoperative SD-OCT scanning for identifying macular pathologies in patients scheduled for cataract surgery. The results showed that routine SD-OCT scans can help identify macular pathologies that might be missed or underestimated by standard fundus bio-microscopic examination, potentially improving patient management.
