Comparative studies on mydriatic effect of tropicamide 0.8% and phenylephrin 5.0% in teenagers & geriatric people

Abstract

Prospective study on the comparison of mydiriatic effect of Tropicamide 0.8% and Phenylephrine 5% in teenagers and geriatric people was carried out in suthrama Eye Hospital madanapalle, India. The main objective of this study was to compare the mydriatic effect of a combination of drug in teenagers and geriatric people. It also evaluated the ADR’s produced and the efficacy of the drug in two age groups. In this study population majority of the subjects were female in group A and male in group B. Among the whole population under study in group A and B no one has reported with any case of congenital anomalies. A number of ADR’s are reported but no serious adverse events had occurred. The study was carried out in 100 eyes ie. 50 subjects whom are divided into 2 groups based on age. The comparison of mydriatic effect was done in each group after instilling one drop of a combination of 0.08% Tropicamide and 0.5% Phenynilephrine. The pupillary size where measured before and after administration of drug and the results were compared. The results showed that there is a large difference in the normal pupil size between teenagers and geriatric people. After dilation the difference in pupil size was statistically significant among the two groups. The study concludes that the pupillary dilation produced by administering 0.8% Tropicamide and 5% Phenylephrine produces higher mydriatic effect in teenagers than geriatric people.
