Surgery
Pilocarpine is sometimes used immediately before certain types of corneal grafts and cataract surgery. It is also used prior to YAG laser iridotomy. 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. The most common concentration for this use is pilocarpine 1%. Pilocarpine is shown to be just as effective as apraclonidine in preventing intraocular pressure spikes after laser trabeculoplasty. Presbyopia
In 2021, the US Food and Drug Administration approved pilocarpine hydrochloride as an eyedrop treatment for presbyopia, age-related difficulty with near-in vision. It works by causing the pupils to constrict, increasing depth of field, similar to the effect of pinhole glasses. Marketed as Vuity, the effect lasts for more than 6 hours. Other
Pilocarpine is used to stimulate sweat glands in a sweat test to measure the concentration of chloride and sodium that is excreted in sweat. It is used to diagnose cystic fibrosis. Adverse effects
Use of pilocarpine may result in a range of adverse effects, most of them related to its non-selective action as a muscarinic receptor agonist.
Apri (āprī) in Sanskrit means "conciliation, propitiation" and refers to special invocations spoken previous to the offering of oblations in an animal sacrifice. Some scholars have proposed however, that these hymns were originally meant for a family ritual centered around Agni, which was then later connected to the animal sacrifice. Aprisuktas
Of the ten Aprisuktas mentioned in Gargya Narayanas commentary,  I.13 and I.142 both invoke  the Narāśaṁsa and Tanūnapāt manifestations of Agni, I.188, III.4, IX.5 and X.110 invoke only the Tanūnapāt manifestation and II.3, V.5, VII.2 and X.70 invoke only the Narāśaṁsa manifestation. References
