Measure
Eye Dilation and Constriction - Left Eye
Participants screened for hyperopia \>+1 diopter using a phoropter, have their intraocular pressures measured using a tono pen, and have their iridocorneal angle measured with a gonio lens. Proparacaine hydrochloride 0.5% eye drops will be used to numb the eyes before measuring intraocular pressures and prior to gonio lens. The following day, the participant will receive one drop of tropicamide and one drop of 1% pilocarpine in the left eye. If the left eye has no response to the 1% pilocarpine, or if the diameter of the pupil returned to baseline size, we will ask participants to come back to the clinic on another day to have the process repeated in the right eye. Tropicamide: One drop will be given to participants 1% Pilocarpine: One drop will be given to participants Proparacaine Hydrochloride: One drop will be given to participants Tono pen AVIA: Participant intraocular pressures measured VG4 Gonio: Participant iridocorneal angle measured Reichert phoropter: Participant screened for hyperopia \>+1 diopter
