Abstract

Introduction: We have adapted the existing , optometry diabetic retinopathy screening pathway and software , so that it can be used for wet AMD fast track referral.
Purpose: To compare the conventional, optometry wet AMD fast track referral service using FAX transmission, with a teleophthalmology service using colour fundus photography transmitted to a central retinal grading centre.
Method: 40 optometry practices involved in diabetic retinopathy screening were enrolled and had modified computer software installed. Referrals were made by conventional fast track FAX to the macular clinic, and patients were photographed by the optometrist and images transmitted to a central grading centre Results of the two pathways were compared in terms of 1)speed of diagnosis and 2)sensitivity and specificity of diagnosis of wet AMD.
Results: Over a ten month period, 62 consecutive patients were referred. The mean time for conventional pathway was 20.8 days (range 3-34),and for new teleophthalmology pathway was 6.9 days (range 1-13). Sensitivity of technician grading of images was 96%, Specificity 53%, and consultant ophthalmologist was sensitivity 96%, specificiity 87%. The technician showed a learning effect with specificity increasing from 30.7% for first 31 patient cohort, to 70.6% for the second cohort. One patient had images that could not be graded.
Conclusion: Rapid referral of wet AMD cases by optometrists using modified diabetic retinopathy screening software, allows fast and accurate diagnosis, and may reduce unnecessary referrals. Retinal grading technicians can be trained to grade wet AMD images.
