Objective: By correlating known diabetes duration with the prevalence of retinopathy, more than 10 years have been estimated to lapse between the onset and diagnosis of type 2 diabetes. Such calculations, however, assumed a linear model, included stages of retinopathy not specific to diabetes, and allowed 5 years for retinopathy to occur after the onset of diabetes. We calculated the duration of undiagnosed type 2 diabetes in outpatients screened for retinopathy in a hospital-based diabetes clinic after correcting these assumptions.

Methods: The authors retrospectively studied 51 eyes of 51 patients with chronic CSC and subretinal or intraretinal exudation documented by optical coherence tomography (OCT), and evaluated the association of hypertension, systemic use of corticosteroids, duration of symptoms, subretinal fibrosis, and large laser scars with the development of PCRD.
Results: Twenty-four eyes (47%) had PCRD and 27 eyes (53%) had serous macular detachment without cystoid retinal changes.
Purpose: To study the pattern of cystoid retinal changes in the posterior fundi of eyes with chronic central serous chorioretinopathy (CSC) using optical coherence tomography (OCT).
Methods: We retrospectively studied 34 eyes with chronic CSC and cystoid retinal changes at the posterior pole documented by OCT. We analyzed the distribution of cystoid retinal changes with respect to the fovea and chorioretinal lesions.
Purpose: To describe changes of the foveal photoreceptor layer using optical coherence tomography (OCT) in central serous chorioretinopathy (CSC) and evaluate the correlation with visual acuity (VA) loss.
Design: Observational case series.
Methods: We studied 28 eyes with acute or chronic CSC using high-resolution OCT.
Purpose: To determine whether photodynamic therapy (PDT) is effective for treatment of chronic central serous chorioretinopathy (CSC).
Methods: Sixteen eyes with chronic CSC and macular detachment documented by optical coherence tomography (OCT) received PDT guided by indocyanine green (ICG) angiography according to the parameters outlined in the TAP Study. One or more laser spots were applied to the areas of choroidal vascular hyperpermeability that corresponded to retinal pigment epithelium decompensation.
