unequal pupil size after cataract surgery

Marketed as Vuity, the effect lasts for more than 6 hours. It works by causing the pupils to constrict, increasing depth of field, similar to the effect of pinhole glasses. In 2021, the US Food and Drug Administration approved pilocarpine hydrochloride as an eyedrop treatment for presbyopia, age-related difficulty with near-in vision. Pilocarpine is shown to be just as effective as apraclonidine in preventing intraocular pressure spikes after laser trabeculoplasty. The most common concentration for this use is pilocarpine 1%. In ophthalmology, pilocarpine is also used to reduce symptomatic glare at night from lights when the patient has undergone implantation of phakic intraocular lenses the use of pilocarpine would reduce the size of the pupils, partially relieving these symptoms. It is also used prior to YAG laser iridotomy. Pilocarpine is sometimes used immediately before certain types of corneal grafts and cataract surgery. It may be used to treat a form of dry eye called aqueous deficient dry eye (ADDE) Surgery It may be used to help differentiate Adie syndrome from other causes of unequal pupil size. It is used to prevent or treat dry mouth, particularly in Sjögren syndrome, but also as a side effect of radiation therapy for head and neck cancer. Pilocarpine stimulates the secretion of large amounts of saliva and sweat. It was originally made from the South American plant Pilocarpus. It is on the World Health Organization's List of Essential Medicines. Pilocarpine was isolated in 1874 by Hardy and Gerrard and has been used to treat glaucoma for more than 100 years. It works by activating cholinergic receptors of the muscarinic type which cause the trabecular meshwork to open and the aqueous humor to drain from the eye. Pilocarpine is in the miotics family of medication. Use is generally not recommended during pregnancy. Other side effects include allergic reactions and retinal detachment. Ĭommon side effects of the eye drops include irritation of the eye, increased tearing, headache, and blurry vision. By mouth it is used for dry mouth as a result of Sjögren syndrome or radiation therapy.

Onset of effects with the drops is typically within an hour and lasts for up to a day. However, due to its side effects it is no longer typically used in the long term management. As eye drops it is used to manage angle closure glaucoma until surgery can be performed, ocular hypertension, primary open angle glaucoma, and to bring about constriction of the pupil following its dilation. Pilocarpine is a medication used to reduce pressure inside the eye and treat dry mouth.
