Diabetic retinopathy study

The documentation of ophthalmologic data of patients with diabetic retinopathy (DR) is described. Special attention has been paid to the standardized grading of opacities of the dioptric media as well as to the assessment of classified arteriolar abnormalities. The reproducibility of these judgments was determined by a double evaluation test. The reliability of the assessment of classified retinal lesions on panorama fundus photographs was reported elsewhere. A further section of the questionnaire that concerns the documentation of the patient's history, of general medical and laboratory findings, and of reasons why individual patients "drop out" from the study, is described in this contribution.

Preliminary results of a controlled study on diabetic retinopathy are reported. Two hundred and fifteen patients with proliferative (PDR) and nonproliferative (NPDR) retinopathy were uniocularly treated by Xenon photocoagulation and followed for a minimum of 6 months--6 years. Intra- and epiretinal new vessel formations (RNF) decreased in treated but increased in untreated eyes at a high statistical significance. A transition of background retinopathy into the proliferative stage was significantly retarded after photocoagulation. An improvement of new vessel formations on the disc (DNF) was not evident after 3 years of follow-up. The progression of preretinal neovascularization (PRNF) was significantly reduced only for 1--2 years after treatment. The incidence of massive vitreous hemorrhages, however, which showed the highest quotient of contingency with PRNF was much lower in treated eyes also after 3 years. The difference was significant only in extensively photocoagulated eyes with more than 100 lesions on average. The effect of photocoagulation on diabetic maculopathy with preservation of a useful visual acuity was highly significant only in diabetics under 60 years of age, the effect increasing with time as the control eyes fared worse. By contrast, in patients over 60 years of age, the course of maculpathy was not influenced, and a linear decrease of visual acuity occurred in both treated and untreated eyes.
