Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2019, Vol 18, Issue 3
Abstract
To determine the effects of diagnostic mydriasis using 1% tropicamide and 2.5% phenylephrine on the distant and near vision of patients attending the Eye Clinic of University of Port Harcourt Teaching Hospital, an interventional‘within-patient’ comparative hospital-based study was conducted over 3 month.The right eyes of 137 subjects requiring diagnostic mydriasis received 1% tropicamide and 2.5% phenylephrine. The left eyes served as control. Visual acuities for distance and near were assessed pre dilatation and at 130 minutes post dilatation using the Snellen’s and near charts respectively.There were 137 study participants- 86 males (62.8%) and 51 females (37.2%). The mean age of participants was 44.87±15.94 years. Visual blurring was noted post dilatation and was commoner with near vision. The mean post-dilatation near VA (N30.68±14.81) for the RE was worse than the mean pre-dilatation near VA (N18.78±16.31), this difference was statistically significant (p=0.0001).Considerable reductions in distance and near vision could occur after dilatation.
