To assess the effect of cyclopentolate 1% on the intraocular pressure (IOP) in a paediatric population.
Twenty children (40 eyes) 5 to 13 years of age (mean 7.7 ± 2.3) were studied. Patients with narrow angle and known or suspected glaucoma were excluded from the study. Subjects’ refraction ranged between –15 and +4.5 D (mean –1.25 ± 5.8 D). The IOP was measured with Goldmann aplanation and with non–contact tonometer before and after administration of the cyclopentolate (one drop, two times at ten minute interval).
After cycloplegia, IOP remained the same in 13 cases, increased in 9 eyes (but stayed inferior to 20 mmHg) and decreased in 18 eyes. Mean IOP by aplanation before and after cycloplegia was respectively 12.75 ± 3.1 and 11.8 ± 3.2 (P=0.02) and with non–contact tonometer respectively 14.5 ± 3.3 and 13.7 ± 3.3 (P=0.08). IOP measured with non–contact tonometer was significantly higher than IOP measured with Goldmann aplanation (P<0.05).
Cyclopentolate 1%, widely used in children, doesn’t seem to increase IOP. This study confirms that values of IOP in children are higher with the non–contact tonometer.
