A group of pseudophakic patients was investigated to determine whether their implants shift along an anteroposterior axis under different conditions of ciliary muscle stimulation. There was no statistically significant change in refraction after either pilocarpine or cyclopentolate administration. A change in anterior chamber depth between the position after pilocarpine and that after cyclopent...

Eye drops used for diagnostic mydriasis may produce systemic side effects in preterm infants. Studies on the pupil dilating and systemic effect of various mydriatic agents yielded conflicting results. We conducted a prospective randomized double-blind study on the systemic effect of two mydriatic eye-drop combinations. Thirty-nine preterm infants were randomly assigned to two groups. An eye-dro...

accurate measurement of refractive error in uncooperative patients and young children, requires cycloplegia. the aim of the present study was to determine whethere cyclopentolate by itself or in combination with 4 times instillation of atropine can be used as a substitute for 10 times instillation of atropine. from 1994 to 1996, 39 patients aged 2-12 years were included in this study. cyclopleg...

PURPOSE To determine the optimal dosage of cyclopentolate for adequate cycloplegia with minimal side effects. METHODS A prospective randomized clinical trial of patients 3.5 to 20 years of age referred to a strabismus clinic during a 1-year period. Eligible patients were randomly divided into three groups. In Group 1, the cycloplegic effect of one drop of cyclopentolate was compared with two ...

The assessment of anterior segment structures has become an important consideration for the planning of ocular refractive and cataract surgery, as well as for diagnosing and treating glaucoma and assessing corneal health. This assessment is typically performed by means of slit lamp biomicroscopy in clinical applications. An objective quantitative assessment of anterior segment structures is not...
