Fundus Autofluorescence Imaging in an Ocular Screening Program

الملخص EN

Purpose.

To describe integration of fundus autofluorescence (FAF) imaging into an ocular screening program.

Methods.

Fifty consecutive screening participants were included in this prospective pilot imaging study.

Color and FAF (530/640 nm exciter/barrier filters) images were obtained with a 15.1MP Canon nonmydriatic hybrid camera.

A clinician evaluated the images on site to determine need for referral.

Visual acuity (VA), intraocular pressure (IOP), and ocular pathology detected by color fundus and FAF imaging modalities were recorded.

Results.

Mean ± SD age was 47.4 ± 17.3 years.

Fifty-two percent were female and 58% African American.

Twenty-seven percent had a comprehensive ocular examination within the past year.

Mean VA was 20/39 in the right eye and 20/40 in the left eye.

Mean IOP was 15 mmHg bilaterally.

Positive color and/or FAF findings were identified in nine (18%) individuals with diabetic retinopathy or macular edema (n=4), focal RPE defects (n=2), age-related macular degeneration (n=1), central serous retinopathy (n=1), and ocular trauma (n=1).

Conclusions.

FAF was successfully integrated in our ocular screening program and aided in the identification of ocular pathology.

Larger studies examining the utility of this technology in screening programs may be warranted.
