What is A Single Low-Dose of Methylphenidate Improves Abnormal Visual Field Testing about?

## Purpose: To evaluate the effect of methylphenidate on visual field testing in healthy adults with abnormal visual field results. ## Methods: This prospective, randomized, controlled interventional clinical trial comprised all patients who had abnormal visual field test results and normal eye examination and ophthalmic history. eligible patients were randomly assigned to either the study group or the control group. all patients repeated their visual field testing. study group patients received a single dose of 10 mg methylphenidate prior to that. the main outcome measures were the percent difference in mean deviation and pattern standard deviation between the second and first visual fields. ## Results: The methylphenidate group had greater improvement in all parameters. mean deviation improved by median 68% (iqr 19%-78%) in the methylphenidate group vs. 27% [-5% to 55%] in the controls. however, this was not statistically significant ( = .83). pattern standard deviation improved by median 49% (22%-59%) vs. 7% [-9% to 45%], respectively ( = .012). the visual fields were also reviewed by 3 masked experienced ophthalmologists. they indicated that the second visual field improved in
