Retinal Vascular Permeability in Diabetic Subjects without Retinopathy Compared with Mild Diabetic Retinopathy and Healthy Controls.

Objective: To investigate retinal vascular permeability mapping as a potential biomarker for diabetic retinopathy in subjects with diabetes with no signs of retinopathy and with mild nonproliferative retinopathy.

Design: This is a case-control study.

Subjects: Participants included 7 healthy controls, 22 subjects with diabetes mellitus and no clinical signs of retinopathy (DMnoDR), and 7 subjects with mild nonproliferative diabetic retinopathy (NPDR).

An Infiltrative Choroidal Lesion.

Purpose: To present a distinctive case of primary choroidal lymphoma diagnosed by choroidal biopsy with MYD88 testing.

Methods: We describe the case of a 55-year-old male with unilateral progressive blurry vision. Fundus examination found a whitish/yellowish infiltrative lesion in the posterior pole with macular edema, which had interval improvement with oral prednisone, followed by worsening on OCT with persistent subretinal hyper-reflective materials.

Early Retinal Detachments Following Open Globe Repair: Incidence and Risk Factors.

Purpose: Risk factors for the development of rhegmatogenous retinal detachments (RRDs) in the early postoperative period following open globe repair (OGR) are not well understood. RRDs are often diagnosed late after OGIs, which can negatively impact visual prognosis. We assessed the incidence and risk factors that predict the development of this complication.

Polypoidal choroidal vasculopathy with an exceptionally elevated pigment epithelial detachment.

Purpose: To present a distinctive case of polypoidal choroidal vasculopathy (PCV) with an exceptionally elevated pigment epithelial detachment (PED).

Observations: We describe the case of a 48-year-old African-American woman who presented with a substantial lesion in the right eye. Fundus examination revealed an exceptionally elevated lesion extending in the inter-papilla-macular region with multiple dark pigmented spots.

Fluorescein videoangiography data analysis protocol for mapping retinal vascular permeability in humans.

Fluorescein video angiographies (FVAs) are a diagnostic tool for eye diseases, such as diabetic retinopathy (DR). Currently, kinetic tracer model methods based on indicator-dilutions theory use FVAs to extract biomarkers (e.g.
