FP958 : Validation of Multicolor imaging of Diabetic Retinopathy lesions vis a vis color fundus photographs

Dr.Sugandha Goel, G17815

Purpose: To analyse the visibility of various Diabetic retinopathy (DR) lesions in Multicolor imaging (MCI) and compare them to corresponding color fundus photography (CFP).Methods: Retrospective review of 130 eyes of 65 consecutive patients of DR who underwent MCI and CFP. Results: Hard exudates (Hex) were seen in 74 (71.2%) eyes. In all 74 eyes, it could be picked up both in CFP and MCI. Cotton wool spots (CWS) were picked up in 29 (27.9%) eyes on MCI and in 27 (26%) eyes on CFP. Retinal hemorrhages were picked up in 83 (79.8%) eyes on MCI and in 82 (72.8%) eyes on CFP. Hex, CWS and hemorrhages were better seen on MCI and in GR images as compared to CFP, BR and infrared (IR) respectively. With CFP as comparator, the sensitivity and specificity of MCI to detect these lesions were more than 90%.Conclusion: Our pilot study validates the efficacy of MCI in picking up lesions of DR vis a vis CFP. MCI has a potential to replace CFP in clinical and DR screening setting.
