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.

Congenital mydriasis is defined as congenital absence of iris sphincter muscle which occurs rarely and shows autosomal dominant inheritance (1-4). It was described by White and Fulton (2) in 1937 for the first time. Fixed and dilated pupil is present from the time of birth, observed more frequently in girls and typically bilateral (1-4). Iris sphincter traumas, pharmacological dilatation and ac...

Cataract, a degradation of the optical quality of the crystalline lens, progressive and age-related, is the leading cause of treatable blindness worldwide. Cataract surgery is the most common surgical procedure performed by ophthalmologists and is the only effective treatment for cataracts. Advances in the surgical techniques and better postoperative visual outcomes have progressively changed t...
