[Developmental aspects of diabetic retinopathy during pregnancy]

The course of diabetic retinopathy (DR) was studied in 93 pregnant patients. Results were compared with data from 98 diabetic non pregnant women. Worsening of initial retinal lesions was observed in 16% of the pregnant group whereas only 6% of the control group showed a similar aggravation. The difference between the two groups was statistically significant (p < 0.05). Argon laser panretinal photocoagulation of pre-proliferative and proliferative DR resulted in no subsequent DR-induced complications. On the other hand, the risk of appearance of DR and/or its worsening during pregnancy depends on initial network but mostly on the duration of diabetes mellitus. In conclusion, regular ophthalmologic examination of diabetic patients especially during pregnancy seems crucial for the early screening of any worsening. Furthermore, the importance of pregnancy planning is emphasized.
