[Diabetic retinopathy and pregnancy]

Area of Science:

• Ophthalmology
• Endocrinology
• Reproductive Medicine

Context:

• Diabetic retinopathy (DR) progression during pregnancy remains a significant clinical concern.
• Understanding the impact of pregnancy on DR is vital for managing maternal and fetal health.
• Existing literature presents controversies regarding pregnancy's effect on DR onset and prognosis.

Purpose:

• To clarify the influence of pregnancy on the development and progression of diabetic retinopathy.
• To differentiate the effects on background versus proliferative diabetic retinopathy.
• To review current management strategies and their implications for pregnant diabetic patients.

Summary:

• Pregnancy poses a low risk for developing retinopathy if none is present initially.
• Background retinopathy may worsen and become proliferative, often improving postpartum.
• Proliferative retinopathy frequently worsens, necessitating vigilant management to prevent vision loss.
• Photocoagulation is the current treatment of choice for proliferative DR in pregnant women, with outcomes similar to non-pregnant individuals.
• However, proliferative DR is linked to significant fetal morbidity.
• Changes in background DR may correlate with glycemic control during pregnancy, highlighting the critical role of rapid diabetic management.

Impact:

• Informs clinical guidelines for managing diabetic retinopathy in pregnant women.
• Emphasizes the importance of pre-conception and regular prenatal ocular screenings.
• Highlights the need for multidisciplinary care involving ophthalmologists and endocrinologists.
• Supports evidence-based treatment decisions for sight-threatening retinopathy during pregnancy.
