Ophthalmologists frequently use mydriatics both for diagnosis (retinal exploration, refraction tests) and for treatment. Cyclopentolate is used to induce quick and successful mydriasis for pediatric eye examination. Hypersensitivity reaction to cyclopentolate is very uncommon, especially in children. We report the case of a child who experienced a hypersensitivity reaction to cyclopentolate dur...

AIM To study the effect of intracameral injection of preservative-free lignocaine to induce pupil dilatation, without using any preoperative dilating eyedrops or intraoperative mydriatics in patients with age-related cataract associated with type 2 diabetes mellitus. DESIGN This was a prospective, observational, and interventional case series conducted at a tertiary eyecare center in rural In...

We report a case of pharmacologic regression of Urrets-Zavalia syndrome, following deep lamellar keratoplasty for severe keratoconus. Sympatholytic and parasympathomimetic drops were administered and a progressive reduction of mydriasis and restoring of pupillary kinetics were observed. Four years after surgery, it was resulting in only slight residual anisocoria.

Two cases of anisocoria that occurred just after the induction of general anesthesia for living donor liver transplantation are reported. Space-occupying lesions were not observed in brain computed tomography. Mydriasis was temporary in both cases, suggesting that the anisocoria was most likely related to Adie syndrome.

Local instillation of thymoxamine eye drops (0-1%) completely reversed the mydriasis produced by ephedrine (5%) but not that produced by ephedrine (5%) together with homatropine (0-5%). Small but significant changes in accomodation were found with ephedrine and with thymoxamine, as well as the larger expected changes with homatropine.
