Due to sponsors convenience.

Phase I Study to evaluate safety and tolerability of PRO-230 (atropine sulphate 0.05%) ophthalmic solution through evaluation of incidence of non-expected adverse events (AE), photophobia, pupillary diameter, incidence of expected adverse events, and best near corrected visual acuity (BNCVA)

A total of 29 healthy volunteers will apply PRO-230 ocular solution on both eyes QD (one time per day) for 14 days. The safety variables will include non expected AE, pupillary diameter and expected AE; tolerability variables will include incidence of photofobia, and BNCVA. Exploratory variables include best corrected visual acuity (BCVA), intraocular pressure (IOP), corneal an conjunctival staining with fluorescein and lissamine green, vital signs (heart rate and blood pressure), and results of the Ocular Confort Index (OCI) questionnaire.

The presence of non-expected AE < 10% will deem PRO-230 as safe; while an incidence of photophobia < 30% will deem PRO-230 as tolerable.
