Impact of automated OCT in a high-volume eye urgent care setting

Optical coherence tomography (OCT) has become standard of care in the diagnosis and management of a myriad of retinal and optic nerve pathology. Access to diagnostic equipment and skilled imaging personnel in the after-hours setting is often limited. We examined the utility and diagnostic indications for automated OCT in a high-volume after-hours clinic within an eye institute.

OCT images obtained over a period of 15 months were reviewed in the context of electronic patient records. Residents and fellows were surveyed regarding their experience with the OCT and its value in emergency patient management.

202 patients and 359 eyes were examined. Complaints prompting imaging included flashes/floaters, metamorphopsia, decreased vision and scotomas. Diagnoses included vascular occlusion, retinal detachment, macular hole, cystoid macular oedema and central serous retinopathy. Of the 25 residents and fellows surveyed, most agreed that the OCT that facilitated delivery of optimal urgent management. OCT also aided in the triage of patients to specialty clinics.

Expanded access to automated OCT in the urgent care setting shows promise for improving the accuracy and timeliness of diagnosis, which can be critical for optimising patient outcomes. OCT also provides clear, immediate documentation of pathology for substantiating medical decision-making.
