Treatment of early diabetic retinopathy with cyclandelate.

In order to assess the effect of cyclandelate on the abnormal permeability of the blood-retinal barrier which occurs in diabetic patients before any other lesions are apparent in the retina a well-controlled, double blind, and paired trial was carried out in 22 patients. The treatments were randomised. The permeability of the blood-retinal barrier was assessed by vitreous fluorophotometry. Each patient was examined before being involved in the trial and then another 3 times with 1 month's interval. The total duration of treatment was 3 months. The results showed that the breakdown of the blood-retinal barrier as evidenced by the degree of abnormal fluorescein penetration into the vitreous suffered a significant decrease in the diabetic patients treated with cyclandelate when compared to the patients submitted to placebo administration, and this effect is particularly apparent in the third month of treatment.
