AbstractIntroduction: Pregnancy Induced Hypertension (PIH) is an entity involving multiple systems; changes during pregnancy bring about many alterations in human body which are reversible. PIH in turn has got its effect on the visual system of the eye involving the retinal vasculature and producing myriad signs and symptoms. Purpose: This study was undertaken to bring out the various retinal changes in pregnancy and their post partum reversal time. Materials and Methods: This was a prospective study done on 100 patients with Pregnancy Induced Hypertension (PIH) who were referred to Department of Ophthalmology, KIMS, Narketpally, from October 2015 to September 2016. Detailed ocular examination including fundoscopy was done in all 100 patients and results were interpreted. Results: Out of 100 patients of pregnancyinduced hypertension (PIH) 16 were gestational hypertension patients, 60 were preeclamptic patients and 24 were eclamptic patients. Headache was the most common symptom encountered in 68% of cases Visual disturbances were seen in 16% of cases .percentage of patients developing retinopathy due to PIH increased as we moved from mild preeclampsia group to eclampsia group. The relationship between retinal changes and severity of PIH was statistically significant ( <0.0001) . Grade 4 retinopathy changes were seen in systolic blood pressure >180mm of Hg and diastolic blood pressure > 120 mm Hg. The percentage of patients developing severe retinopathy changes due to PIH was directly proportional to BP. Range of gestational age at which most of the patients developed PIH was from 3034 weeks.Pregnancy induced retinopathy changes were seen more in primigravidas. Reversal of signs and symptoms l occurred in all the cases by 10 weeks postpartum. Conclusion: We conclude that fundus changes in PIH are proportional to severity of PIH and BP, all signs and symptoms including visual acuity are reversible with proper control of PIH and periodic fundus examination and follow up is mandatory to prevnent complications.
