Electrophysiological changes in juvenile diabetics without retinopathy.

Several components of the electroretinogram were studied in 31 juvenile diabetics and 15 age-matched normal controls. The diabetic group consisted of 18 patients without retinopathy and 13 with mild background retinopathy. Oscillatory potentials were measured at low-stimulation energies. Significantly reduced amplitudes and component-specific delayed peak implicit times were found in both diabetic groups compared with the data from the controls. Similar results were obtained in the photopic and scotopic electroretinogram. From these findings, we suggest that retinal dysfunction is already present in juvenile diabetics without photographic evidence of retinopathy after a mean duration of diabetes of 7 years.

[Data processing at the special diabetes ambulatory center of the Innsbruck Ophthalmology University Clinic--electronic data processing in ophthalmology].

During the last 2 years, a personal computer in the special diabetes department of Innsbruck University Eye Hospital has not merely facilitated statistical analysis; without the PC such analysis would not have been possible. Logistically, the most important function is data acquisition, because the system only works if all data are entered. In addition to data processing, word processing, statistical analyses, and chart processing using graphics software are all done on the PC. The system is currently being developed further to include on-line access to literature databases via Datex-P and additional workstations. After 3 years of experience with the PC it is difficult to imagine doing scientific work without it.

[Effect of prostaglandin synthesis inhibitors of diabetic cystoid macular edema].

In most cases, diabetic macular edema is treated successfully with central laser photocoagulation. However, only few studies report such favorable results in cystoid macular edema, which has a poor visual prognosis. In the present prospective study on diabetics with cystoid macular edema, aged less than 40 years, a better visual outcome was obtained in patients treated with prostaglandin synthesis inhibitors than in an untreated group.

[Visual status in diabetic maculopathy after central photocoagulation].

Diabetic macular edema is shown to be treated successfully by central focal argon laser coagulation in most cases. Since February 1986, diabetic patients with macular edema were evaluated prospectively and treated by focal argon laser coagulation and/or grid pattern. A second group of diabetic patients with comparable macular edema and similar retinal changes was explored retrospectively. Visual acuity after treatment in relation to preoperative visual acuity was measured and statistically compared with visual acuity of the second group without laser treatment. The results show that laser treatment is important for stabilization of visual acuity but does not increase visual acuity beneath 0.2. Indications for treatment are discussed.
