Association of retinal sensitivity with gestational hypertension and obesity
Background: Pregnancy-induced hypertensive disorders occur in about 5% to 8% of all pregnant women in the world and are associated with various pathological changes in the retina due to vasospasm which might have long-term effects on other vital organs too.

| Summary: | Background:
Pregnancy-induced hypertensive disorders occur in about 5% to 8% of all pregnant women in the world and are associated with various pathological changes in the retina due to vasospasm which might have long-term effects on other vital organs too. These may cause changes in retinal sensitivity which can be measured by static automated perimetry. Obesity in pregnancy also carries the risk of development of hypertension (HTN) and, therefore, various complications in both the mother and fetus.
Aim:
The aim is to study and compare retinal sensitivity by static automated perimetry in pregnant females with HTN and/or obesity.
Setting and Design:
This was a prospective cross-sectional study in a tertiary care center.
Materials and Methods:
Fifty pregnant females with HTN and/or obesity as cases and 54 as controls underwent systemic and ocular examination including retinal sensitivity measurement at 20 and 32 weeks of gestation.
Statistical Analysis:
Statistical software SPSS version 22 was used.
Results:
A significant decrease in mean retinal sensitivity (−7.71 ± 3.67 decibels, P < 0.001) and foveal sensitivity was observed in cases at 32 weeks of gestation compared to controls. With a 5 mmHg increase in systolic blood pressure, retinal sensitivity decreased by 0.795 decibels.
Conclusion:
Gestational HTN was associated with decreased retinal sensitivity compared to normal pregnant females without any observable retinal changes. Noninvasive investigation such as automated perimetry thus can provide us with valuable information regarding vascular changes in the retina which can involve other vital organs including placental circulation at the same time. |
