[Comparative studies of pilocarpine gel and pilocarpine eyedrops]

The influence of pilocarpine gel 4% and pilocarpine eye drops 4% or 2% on the optical and ophthalmological parameters pupil diameter, intraocular pressure, ametropia and visual acuity, range of accommodation, and nocturnal visual acuity with and without blinding was investigated. The tendency to amplify the myopia and impair nocturnal vision acuity with and without blinding was greater with eye drops than with gel. There was no significant difference between gel and eye drops as regards their effect on other parameters.
