简要总结
This study will perform several objective and subjective measurements of the eye and vision before and after a week of using 0.01% concentration atropine drops. These measurements will help to obtain a comprehensive understanding of the side effects of this concentration of atropine and determine if the drops would be tolerated as a possible preventative treatment for nearsightedness.
详细描述
Atropine drops are commonly used to dilate the eye and prevent the ability to focus and also slow the progression of nearsightedness. Low concentration (0.01%) atropine slows the progression of myopia 60% to 83% while causing less side effects than high concentration (1.0%) atropine though still showing an effect on pupil size and pupil response.This study is a prospective cohort study in which several objective and subjective measurements will be taken before and after the use of 0.01% atropine for a week to determine the effect of this concentration on 1. vision at distance and near; 2. pupil size; 3. focusing ability, accuracy, and change; 4. symptoms, including subjective vision, headaches, light sensitivity, drop comfort; and 5. pressure in the eye. This will allow us to determine the effect these drops have on the eye and whether or not patients would be willing to use them as a possible preventative treatment for nearsightedness. The investigators expect to find that the drops will not affect vision, will increase pupil size, decrease focusing ability and accuracy (but not clinically meaningfully), cause some light sensitivity, and have no effect on eye pressure. The investigators expect that patients would be willing to use these drops to control nearsightedness even after experiencing the side effects.

结局指标
主要结局
Diameter of the Pupil Measured With a Neuroptix Pupillometer
时间窗: Baseline (before) and one week after beginning treatment with drops
Change in pupil size between baseline visit and follow up visit (after one week on treatment) in millimeters to the nearest tenth of a millimeter
Visual Acuity With Bailey-Lovie logMAR Visual Acuity Charts
时间窗: Baseline (before) and one week after beginning treatment with drops
Investigators will measure the change in high contrast distance and near logMAR visual acuity and low contrast distance logMAR visual acuity between baseline visit and follow up visit (after one week on treatment).
次要结局
- Eye Focusing Measured by the Closest One Can Read a Letter and Focusing Accuracy Measured by an Autorefractor(One week after beginning treatment with drops)
- Change in Subjective Assessment of Potential Side Effects by Asking the Same Questions Before and After Administration of Eye Drops.(Baseline (before) and one week after beginning treatment with drops)
- Change in Intraocular Pressure Using a Tonopen(Baseline (before) and one week after beginning treatment with drops)
- Ability to Change Focus From Far to Near Measured by Stimulating and Relaxing Focus of the Eyes as Many Times as Possible in One Minute.(Baseline (before) and one week after beginning treatment with drops)
