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.
