Ultra-wide-field imaging for cytomegalovirus retinitis.
OBJECTIVE
To compare the Optomap imaging system (Optos PLC, Dunfermline, Scotland) with conventional fundus photography in patients with cytomegalovirus (CMV) retinitis.


METHODS
Patients treated at Rush University for acquired immune deficiency syndrome and CMV retinitis were studied prospectively. Conventional nine-field photography and Optomap ultra-wide-field photography were performed on the same day. A patient satisfaction questionnaire was completed. The main outcome measures were total retinal area imaged, area of CMV retinitis imaged, and patient satisfaction.


RESULTS
Twelve eyes met the inclusion criteria. Ultra-wide-field imaging captured 48.3% greater retinal area and 40.0% greater CMV retinitis area compared with standard photography. Standard photography missed peripheral CMV lesions in two eyes. The patient satisfaction survey indicated a preference for ultra-wide-field imaging based on increased comfort and decreased imaging time.


CONCLUSIONS
The ultra-wide-field Optomap imaging system tended to capture greater areas of total retina and peripheral CMV retinitis lesions. Patients tended to prefer ultra-wide-field imaging because of the perceived time requirements and comfort of use.
