During ocular surgery, miosis (pupil constriction) can occur due to various reasons such as the use of anesthetics, inflammation, or intraoperative manipulations. Pupil constriction can cause difficulty in visualization and manipulation of the intraocular structures, which can increase the risk of surgical complications.
To prevent miosis during ocular surgery, prophylactic measures can be taken such as the use of pharmacological agents that dilate the pupil (mydriasis). These agents include topical anticholinergics such as atropine, tropicamide, and cyclopentolate. These agents work by blocking the action of acetylcholine, which is responsible for pupil constriction.
In addition to pharmacological agents, other measures can also be taken to prevent miosis during ocular surgery, such as the use of intraoperative irrigation and the avoidance of mechanical manipulation of the iris. It is important to discuss the potential risks and benefits of these measures with your ophthalmologist before undergoing ocular surgery.
