ABSTRACT

Aim of study: to evaluate the beneficial effect of Tropicamide 1% eye drop in measurement of refractive errors in patients aged 10-30 years. Patients and methods: A descriptive study conducted in Ibn ALHaithem Teaching Eye Hospital. A 48 patients were included in this study, with regulating sequencing of cycloplegic agents the near point of accommodation using RAF ruler with auto refraction before and after each eye drop. For each patient, the spherical equivalent was calculated before and after the instillation of each eye drop. Each patient was instilled with Tropicamide 1% eye drop ( 2 drops in conjunctival sac 5 min apart ) and auto refracted after 30 min from last drop , on other day patient was instilled with cyclopentolate 1% eye drop ( 2 drops in conjunctival sac 5 min apart ) and auto refracted after 30 min from last drop. Result: 48 patients of 62 patients complete both tests. Both eyes were measured. RAF ruler results were neglected because the results after instillation of both eye drops were beyond the scale of the ruler ( more than 50 cm ). Tropicamide 1% eye drop appeared to be effective as 71.5% as cyclopentolate 1% eye drop in cycloplegic effect in age group 10-30 years irrespective to the refractive state of patients. In myopic patients, irrespective to the age of the patients and degree of refractive error, tropicamide 1% eye drop appeared to be effective as 86% as cyclopentolate 1% eye drop. In hyperopic patients, irrespective to the age of the patients and degree of refractive error, tropicamide 1% eye drop was effective as 58% as cyclopentolate 1% eye drop. Conclusion: there is no statistically significant differences in cycloplegic effect between tropicamide 1% eye drop and cyclopentolate 1% eye drop on auto refraction in myopic patients group.
