Can you give some details on this? Pros/cons
Standard commercially available atropine for eye dilation prior to procedures is a 1% solution. Atropine is an anti-cholinergic (anti-rest-and-digest) which acts on nerve receptors naturally existing in your eye. "Low dose" or more appropriately low strength atropine is "compounded" by a pharmacy as 0.01%, 0.025%, and 0.05% solution. By far the most common use for it is to
slow the progression of (not reverse) myopia in children and adolescents either alone or in conjunction with "OrthoK" type hard lenses worn at night that act as braces to remodel the shape of the eyeball. Studies have shown benefit for at least 2 and possibly 3 years for the low dose atropine during childhood/adolescence.
Side effects with this indication(use) are not common and are typically limited to temporary (1-5min) burning sensation, bad taste in mouth, and temporary light sensitivity (used at night before bed).
A newer use for low dose atropine that does not yet have the same level of robust double blinded placebo controlled studies is for "floaters" in adults. Again, there is not nearly as much data as for myopia in children, but preliminary efficacy has been excellent and side effects are uncommon and similar to those listed above.
The strength is between 1/20th to 1/100th of the commercially available formulation. "Compounded" means that it is either sterilely diluted down from the commercial formulation or made directly from the raw chemical ingredients and sterilized in a strictly controlled (and heavily regulated) cleanroom.
Your ophthalmologist would be able to give you more information and write a script if you'd like to try it
[And before anyone asks or assumes this info didn't come from "ask Google", nor do I have anything whatsoever to gain from anyone having their doc write a script for it]
