Objective: Visual reaction time (VRT) is time required for purposeful voluntary response to visual stimuli. It includes the time required in central information conducting process. Diagnosis of quantitative visual function of the central visual pathway and cognitive ability of subjects can be done through this test. PIH is profound disorder prevalent in 2-3% population worldwide causing high mortality and morbidity. Pregnancy Induced Hypertension (PIH) was studied to cause impairments in Visual functions of the female during third trimester due to raised blood pressure. When PIH advances to Eclampsia it presents with seizures and transient blindness. PIH also has been found to cause cognitive disabilities. Present study was conducted to evaluate the responsiveness and cognitive disabilities developed because of raised blood pressure. Methods: Cases were 50 Pregnancy Induced Hypertensive and Controls were age matched 50 Normotensive Pregnant Females both in third trimester. VRT was measured by computer based reaction time software in all the cases and controls. During the reaction time testing, Visual stimuli was given for three times and minimum reaction time was taken as the final reaction time for that sensory modality of that subject. The results were statistically analyzed and were recorded as Mean ± S.D and Student's paired t-test was applied to check the level of significance. Results: Study showed that VRT in Pregnancy induced Hypertensive females was significantly raised when compared to Healthy Normotensive Pregnant females. Values of VRT was found significantly increased in multiparous pregnancy induced hypertensive females when compare to primiparous pregnancy induced hypertensive females. Conclusion: Pregnancy induced Hypertension can be concluded to cause damage to all the body tissues including the central and peripheral nervous system. Mental processes are involved in identification of stimulus, response selection, and programming and this takes certain time which was more in females with PIH when compared to healthy normotensive Pregnant females. Widespread endothelial damage and dysfunction, systemic toxicity, coagulation defects, and an increased systemic inflammatory response, poses risk factors for hearing disorders during PIH.
