Abstract: :
Purpose: We propose the use of the Heidelberg Retinal Tomography (HRT) to document macular changes in Age-related Macular Degeneration (AMD) and Diabetic Retinopathy (DR) patients (pts). Methods: AMD pts (23 eyes, 20 pts), DR pts (26 eyes, 25 pts), and Control (C) pts (25 eyes, 21 pts) were examined with the HRT. All patients (AMD, DR, C) had visual acuity (20/20-20/40). We used the area 2.83 mm2 generated by Heidelberg Eye Explorer (HEE) v1.3.0.0 to examine the absolute depth of the macular areas, designated as "cup depth." The foveola was used as the center of the area examined. Results: The age ranges of the patients were: AMD (50-92 yrs, avg = 69.7 yrs ± 9.604), DR (31-80 yrs, avg = 55.9 yrs ± 14.7), and C (20-80 yrs, avg = 48.9 yrs ± 15.9). Analysis of age vs macular thickness in the control group showed that there was no correlation between global, temporal, and nasal mean depth in the age groups of 20-39 yrs, 40-59 yrs, and 60-80 yrs. Conclusion: Heidelberg Retinal Tomography may be used in evaluating changes in macular thickness in patients with early Age-related Macular Degeneration, Diabetic Retinopathy, and good visual acuity.
