  • Abstract
  • Look Inside

We evaluated the effect of topical instillation of an aldose reductase inhibitor (ARI) on the protein concentration in the aqueous humor in 74 eyes of 37 diabetic patients. The findings were compared with another group receiving placebo solution. Assign-ment of patients to ARI and placebo group was randomly decided. Eyedrops were instilled 4 times daily for 3 months. Aqueous protein concentration was measured with a laser flare-cell meter at 2, 4, 8, and 12 weeks. Analysis of variance showed that topical ARI suppressed increase of protein in patients with early background retinopathy (p< 0.05). In eyes with advanced background, prepro-liferative or proliferative retinopathy, aqueous protein concentration was significantly lower in ARI group than in placebo group at 4, 8 and 12 weeks of treatment (t-test: p< 0.01). These find-ings seemed to show that topically instilled ARI would suppress breakdown of blood-aqueous barrier in diabetic eyes.
