Abstract Details

Purpose:

Our goal was to assess the efficacy of a swept-source optical coherence tomography (SS-OCT) based biometry device for diagnosing macular abnormalities in patients scheduled for cataract surgery

Setting:

Department of Ophthalmology, Shaare Zedek Medical Center, Jerusalem, Israel

Methods:

In this retrospective study an experienced technician reviewed macular scans of consecutive patients obtained between November 2017 and January 2018. Patients over the age of fifty that were scheduled for cataract surgery were included. Scans were acquired by a SS-OCT biometry device (IOLMaster-700, Carl Zeiss Meditec AG, Jena, Germany). Data was collected from the surgical eye of each patient. Results were compared to volumetric macular SD-OCT scans (Heidelberg Spectralis, Heidelberg Engineering, Germany) performed on the same day and interpreted by an experienced retina specialist. Sensitivity and specificity for macular pathology detection by the SS-OCT were assessed.

Results:

Four hundred and sixty eyes of 460 patients were included, of which 40 scans (8.7%) were non-interpretable by macular SD-OCT due to advanced cataract, 256 macular scans (55.6%) were within normal limits and 164 scans (35.7%) had clinically significant macular pathology. The overall specificity and sensitivity of the SS-OCT were 92% and 22%, respectively. Higher sensitivity rates were observed in eyes with vitreomacular traction (100%) and epiretinal membrane (ERM) with retinal thickening (82%), whereas lower rates were detected in eyes with cystoid macular edema (38%), AMD (12%) and mild ERM (4%).

Conclusions:

Although macular evaluation with SS-OCT based biometry cannot substitute a dedicated macular OCT, it may assist in diagnosing some significant macular abnormalities in patients scheduled for cataract extraction. Cost-effectiveness of routine preoperative macular OCT should be further studied.
