[A myopia study of glaucoma patients following pilocarpine instillation]
Aim:
Our research studies transitory myopia induced by Pilocarpine treatment in glaucoma patients.
Material And Methods:
48 patients with open angle glaucoma were selected, visual acuity and refraction were measured before and after the instillation of Pilocarpine 2%, for two hours. Induced myopia was compared for different ages and it was established the influence of Timolol and Acetazolamide administered in the same time.
Results:
Transitory myopia is important in young patients, reduced after 50 years and absent after 70 years. Acetazolamide increases myopia, Timolol has no effect on refraction.
Conclusions:
The study confirms the unpleasant effect of Pilocarpine and suggests not performing refractometry in the first two hours after the instillation of the drug.
