Abstract
PURPOSE: Patients afflicted with ocular complications of diabetes represent a diverse demographic who often cannot undergo spectral-domain optical coherence tomography (SD-OCT) imaging of the retina due to postural restraints. Our pilot study compared imaging acquisition methods using SD-OCT in the handheld (HH) mode versus the conventional tabletop (TT) method. METHODS: Our study included 22 undilated eyes of 22 subjects (mean ± SD age, 35.8 ± 16.8 years) imaged using HH and TT iVue SD-OCT (Optovue, Fremont, CA). Statistical analysis was performed using Microsoft Excel 12.2.7 (Microsoft Corporation, Redmond, WA) software with an accepted significance of P < .05. RESULTS: Strong intraclass correlation coefficient was observed for (1) overall (.97), superior (.93), and inferior (.94) ganglion cell complex thickness, and (2) central (.98), inferior (.90), superior (.92), nasal (.94), and temporal (.93) macular retinal thickness. Mean scan quality index was adequate but lower in HH versus TT SD-OCT (62.8 vs 68.1, respectively; P < .0001). Multiple attempts for adequate imaging were required more frequently in HH versus TT SD-OCT (34% vs 5%, respectively; P < .001). CONCLUSION: HH SD-OCT may be a feasible alternative to TT SD-OCT in select situations, especially in patients suffering from diabetic complications with limited mobility.
