ABSTRACT Objective: To evaluate the impact of selective laser trabeculoplasty (SLT) on resource savings and medication costs. Methods: Retrospective study of patients with open-angle glaucoma (OAG) who underwent SLT as a replacement therapy for eye drops and were followed for up to 1 year. The ability to reduce intraocular pressure (IOP) and the amount of eye drops were evaluated, as well as the monthly cost of medications during the follow-up. The annual cost of medications was also calculated. The results […]

ABSTRACT Objective: To analyze the diabetic autonomic neuropathy through the comparison between the pharmacological mydriasis in patients without diabetes and with type 2 diabetes.
