Effect of the Duration of Eye Closure on Therapeutic Mydriasis
Journal Title: Ophthalmology and Vision Science - Year 2017, Vol 1, Issue 4
Abstract
Purpose: This study seeks to establish the effect of the duration of eye closure on therapeutic mydriasis. Method: This was a prospective cross-sectional survey involving 60 participants who were put into two groups of 30. One drop of a combination of cyclopentolate 1% and phenylephrine 2.5% eye drop was instilled on both eyes of each participant. Group A was asked to close eyes for 5 minutes and group B for 20 minutes. The pupils were assessed for dilation with torchlight after one hour. Results: Out of the 60 participants, majority 38 (63.33%) were females. The females dominated both Groups A 21 (70.0%) and B 17 (56.67%). Overall, the age group 51+ had the highest frequency 25 (41.67%). Full pupil dilation was achieved in 80.0% of participants in Group A as compared to 23.33% of those in Group B, despite the longer period of eye closure in Group B. There was a significant difference between Groups A and B in terms of degree of pupil dilation (p ≤ 0.05). Conclusion: Shorter duration of eye closure during therapeutic pupil dilation is ideal in achieving maximal dilation. The long periods of eye closure that clients are subjected to in eye clinics needs to be avoided.
