Marked reductions in visual impairment due to diabetic retinopathy achieved by efficient screening and timely treatment.

Purpose: Diabetic retinopathy (DR) is the most common complication of diabetes and needs to be diagnosed early to prevent severe sight-threatening retinopathy. Digital photography with telemedicine connections is a novel way to deliver cost-effective, accessible screening to remote areas. Screening for DR in a mobile eye examination unit (EyeMo) is compared to traditional service models (i.

Postprandial hyperglycemia and insulin response are affected by sea buckthorn (Hippophaë rhamnoides ssp. turkestanica) berry and its ethanol-soluble metabolites.

Background/objectives: Repeated postprandial hyperglycemia and subsequent mild, late hypoglycemia as well as high postprandial insulin response lead to metabolic events that may eventually develop into type 2 diabetes. The aim of this study was to assess how sea buckthorn berries as well as two sea buckthorn extraction residues modulate the postprandial metabolism after a high-glucose meal.

Subjects/methods: Ten healthy normal-weight male volunteers consumed four study breakfasts, one control (A) and three sea buckthorn meals on four distinct study days.

Digital imaging and microtexture analysis of the nerve fiber layer.

Purpose: To describe the design of a digital retinal nerve fiber layer (RNFL) imaging techniques and present a new approach to measure the differences in RNFL patterns.

Methods: A digital camera body is connected to a wide-angle camera to obtain images of the RNFL, which are displayed in workstations throughout the clinic. In the on-line archive, images in Joint Photographics Experts Group (JPEG) format (100 KB per frame) are used.

The application of teleophthalmology in examining patients with glaucoma: a pilot study.

Purpose: To test the feasibility of teleophthalmology applications in examining patients with glaucoma, test its use for training purposes in an ophthalmology residency program and as a consultation link between primary healthcare unit and university eye clinic, and to introduce a preliminary model for economic assessment of telemedicine application in ophthalmology.

Methods: A video slit-lamp, an automated perimeter, a nonmydriatic fundus camera and a videoconferencing system were installed in a healthcare center in a rural area. Twenty-nine patients with glaucoma were examined in the rural healthcare center instead of the university eye clinic.

Fluorometry of the crystalline lens for correcting blue-on-yellow perimetry results.

Purpose: Optical and neural sources of short wavelength sensitivity should be separated in the assessment of the results of blue-on-yellow (B/Y) perimetry. It has been shown previously that lens autofluorescence is related directly to lens yellowing and age. The aim of this study was to find out if B/Y perimetry results can be better corrected by using lens fluorometry than by age.
