[Clinical features of diabetic retinopathy in pregnancy].

INTRODUCTION

Pregnancy is a risk factor for progression of diabetic retinopathy (DR). Despite the common opinion about the regression of DR after childbirth, it is possible for the disease to progress aggressively, which can cause loss of visual functions when treated untimely.

PURPOSE: To present clinical cases with different course of development of DR in pregnant women with type 1 diabetes mellitus (DM1).

MATERIAL AND

METHODS

Five pregnant women with DM1 lasting more than 8 years were examined. Glycemic level of all patients was higher than normal (glycated hemoglobin (HbA1c) of more than 6.1%). Ophthalmologic examination was carried out including fundus photography, optical coherence tomography (OCT) of the macular area, Angio-OCT.

RESULTS

The most significant factors in the progression of DR in pregnant women are DR1 compensation, severity and stabilization of DR during the preconception period, presence of a concomitant pathology. Timely detection of signs of progression of DR and therapeutic measures taken during pregnancy, in particular laser coagulation, were shown to stabilize the course of the disease and prevent loss of vision in pregnant women with DM1.

CONCLUSION

Clinical course of DR in pregnancy can vary between absence of manifestation, stabilization, and progression. Progression of DR during pregnancy is determined by a number of factors including compensation of DM during the preconception period and throughout pregnancy, severity and stabilization of retinopathy during the preconception period, and presence of a concomitant pathology. Timely detection of the signs of DR progression and its treatment, in particular laser coagulation of the retina, can help stabilize the course of the disease during pregnancy. The course of DR may be aggressive in some pregnant women involving progression in the postpartum period, which warrants active monitoring of patients with retinopathy after childbirth.
