Purpose: This study aimed to assess the monocular effect of cycloplegia on accommodation.
Methodology: Participants in this experimental study ranged in age from 18 to 30. The patients were chosen from various Sankara eye hospitals units. The study excluded patients with visual anomalies, strabismus, presbyopia, aphakia, and pseudo-phakia. Before and after administering 1% cyclopentolate to the other eye, the individuals underwent pupillography, the near point of accommodation test (NPA), the monocular estimating method (MEM), and the accommodative facility test (AF).
Result: 20 individuals in all, of whom 45% were women and 55% men, were included in the study. Prior to the administration of Cycloplegic, the mean pupil value was 4.0185%, and it was 4.3175% post cycloplegic effect. Similar to this, the un-dilated eye's mean NPA value was 8.3 while the dilated eye's mean value was 9.55. Before the injection, the mean value of AF was 8.5, and it was 7.2 afterward. Additionally, the mean MEM value of the un-dilated eye was 0.225, and the subsequent value was 0.3125.
Conclusion: After the cycloplegia instillation, there was a modest change in the monocular undiluted eye's pupil size. All individuals' monocular un-dilated eyes showed an increase in NPA value and a decrease in AF, although their MEM remained stable in 70% of cases but showed a minor shift in 30% of cases.
