Prevalence of diabetic retinopathy in Peruvian patients with type 2 diabetes: results of a hospital-based retinal telescreening program.

Objective: To estimate the prevalence of diabetic retinopathy (DR) in patients with type 2 diabetes and to determine any association with clinical factors.

Methods: This hospital-based screening project was designed to prospectively detect the presence of DR in patients with type 2 diabetes by grading images acquired with a digital retinal camera.

Results: Of 1 311 patients screened, appropriate retinal images were obtained in 1 222 subjects (93.

Improving diabetic retinopathy screening ratios using telemedicine-based digital retinal imaging technology: the Vine Hill study.

Objective: To evaluate the impact of a telemedicine, digital retinal imaging strategy on diabetic retinopathy screening rates in an inner-city primary care clinic.

Research Design And Methods: This retrospective cohort study included all diabetic patients aged > or = 18 years (n = 495) seen at Vine Hill Community Clinic between 1 September 2003 and 31 August 2004. Patients were offered ophthalmology referral or digital screening.

A portable visual acuity device used in diabetic retinal screening.

Purpose: To correlate visual acuity measured with the Optec 800 to the gold-standard Early Treatment Diabetic Retinopathy Study (ETDRS) chart.

Design: Prospective, cross-sectional study.

Methods: Forty patients of the Vanderbilt Eye Institute agreed to undergo visual acuity testing.

Monoscopic versus stereoscopic photography in screening for clinically significant macular edema.

The purpose of the study was to determine whether monoscopic photography could serve as an accurate tool when used to screen for clinically significant macular edema. In a masked randomized fashion, two readers evaluated monoscopic and stereoscopic retinal photographs of 100 eyes. The photographs were evaluated first individually for probable clinically significant macular edema based on the Early Treatment Diabetic Retinopathy Study criteria and then as stereoscopic pairs.
