Visual Field Tests Clinical Trial
Official title:
Methylphenidate Effect on Performing Humphrey Visual Fields
Study will include adults with abnormal visual fields. Half of them will be given either methylphenidate 10mg 2 hours before repeating the visual field test. the rest will serve as controls. All Subjects will also have a complete eye examination, a short questionnaire and a questionnaire to screen for attention deficit disorder. The investigators will compare the visual field results between the 2 tests.
Healthy adults with abnormal visual fields will be offered to participate Subjects will have
a complete ophthalmic examination including dilated fundus examination.
Subjects with clear explanation for a visual field defect (e.g. optic neuropathy or retinal
disorder) will be excluded from the study the subjects will be randomly assigned to the study
group and control group using a 1:1 allocation.
Subjects in the study group will be provided with a single tablet of methylphenidate 10 mg to
be taken orally 2 hours before repeating their visual field test.
The control group will not receive any placebo Both groups will repeat their visual fields.
Both groups will fill out a short questionnaire to evaluate their experience in the second
visual field test.
The study group will also fill out a screening questionnaire to rule out previously
undiagnosed attention deficit disorder.
Two experienced ophthalmologists will separately interpret the visual fields results and
compare the first and second visual fields of each subject, while being blinded to which
group he was in.
Subjects will be provided with their test results and the ophthalmologist interpretation.
