Diabetic Retinopathy Trends in a Digital Screening Program of Eight and Half Years

Objectives: To share the trending of Diabetic Retinopathy (DR) over eight and half years period digital screening program of DR in Bangladesh at a tertiary eye hospital. Methods: This study analyze 8 and 1/2 years (102 months, from July 2010 to December 2018) findings of a digital screening and subsequent grading programs of DR in a tertiary eye care centre. A total 45289 eyes of 22645 diabetic person underwent retinal photography.7818 (17.26%) retinal Photographs were excluded because of unassessable for grading remaining 37471 retinal photographs were analyzed. Screening was performed by non-mydriatic digital fundus camera. Optometrist & Ophthalmologist review of all photographs were done at three level of grading system. Evaluation of the percentage distribution of degree of retinopathy was done. Data analysis was done by SPSS software version 16.0. Results: A total of 22645 patients (64.12 % male,35.88 % female) with mean age of 55.58 ± 9.88 (±SD) years were under went DR screening during a 8.5 years period. Features of DR was found in 18958 of 37471 (50.59%) retinal photographs. Non-proliferative diabetic retinopathy (NPDR) was documented in 14457 of 37471 photographs (38.59 %), while 4501 of 37471 photographs (12.00%) showed proliferative diabetic retinopathy (PDR). Diabetic Macular Edema (DME) was found in 10788 (28.79 %) of total 37471 assessable photograph and (56.90 %) of a total 18958 DR. Conclusion: DR is highly prevalent among Bangladeshi patients. In order to provide a sensitive, cost effective and easily accessible DR screening, digital imaging is a useful means
