Comparing Three Models of Community-Based Diabetic Retinopathy Screening, Treatment, and Awareness Creation Services in Southern India / South Kerala.

Background: The aim of the study was to evaluate the effectiveness of three models of diabetic retinopathy (DR) screening from an economic perspective and their effectiveness in awareness creation, screening, and ability to deliver treatment.

Materials And Methods: Analysis of a prospective screening program for diabetes mellitus and DR in South Kerala was done. Three models were created: Model 1: blood screening camp, Model 2: comprehensive eye camp, and Model 3: institution-based screening camp.

Progression of Subclinical Pachychoroid Neovasculopathy to an Active Neovascularization in the Presence of Acquired Vitelliform Lesions.

We describe a unique case of bilateral acquired vitelliform lesions in a 67-year-old-female with pachychoroid associated with subretinal fluid in the right eye (OD) and a nonexudative choroidal neovascular membrane (CNVM) in the left eye (OS). Multimodal imaging performed at baseline and over the ensuing two years showed an increase in the OS vitelliform lesions with a concurrent transformation of quiescent CNVM to an exudative form. Further studies are warranted to gain better insight into the etiopathogenesis of these vitelliform lesions in pachychoroid and their potential role in instigating CNVM activation.
