%X Objectives: To determine the relationship between Macula Pigment Optical Density and Visual Performances (foveal sensitivity, Contrast sensitivity and stereo acuity) in patients with Dry Age Related Macular Degeneration accompanied with Macular Drusen. To evaluate the awareness of patients about the condition Methods: A descriptive cross sectional study according to convenience sampling was carried out with 80 patients (160 eyes) aged 44-65 for duration of 14 months. Data was recorded in each subject by carrying out a questionnaire including Demographic profile, Visual Functions; (Foveal sensitivity ¨Cmeasured by Humphrey Field Analyzer), Contrast sensitivity (by lea contrast acuity chart), stereo acuity (by TNO test). Thickness of macula & presence of drusen -measured by Cirrus 5000 spectral domain Optical Coherence Tomography and Macula pigment optical density by Zeiss Visucam 500 MPOD mode ,AMD was graded into 3stages by the presence of 15 or more macular drusen > 63¦Ìm and all were again divided in to 3 sub-groups according to MPOD levels[2]. All data were analyzed using SPSS software. Results: Mean MPOD levels in 160 subjects, Stage-1 - 0.41, Stage-2 -0.31, Stage-3 -0.17 Mean Foveal sensitivity (MFS); low range=15 dB, mid-range=21, high-range=26dB, Mean Contrast sensitivity; low-range=25%, midrange= 5%, high-range=2.5% and Mean Stereo acuity; low range=480 sec of arc, mid-range=240 sec of arc high-range=60 sec of arc. Patients awareness score -7/7=10pt, 7/6=0pt, 7/5=12pt, 7/4=8pt, 7/3=15pt, 7/2=16pt, 7/1=34pt 7/0=1105pt. Conclusion: People aged 45-65 with drusen maculopathy was found with a significant relationship of decreasing macula pigments (lower MPOD values), as a result of it they are at a considerable risk of decreased visual performances. 72.5% patients from the study group were totally unaware about the condition.
