DOI: 10.1590/S1679-45082017AI4040 A 45-year-old woman sought ophthalmologic care complaining about a sudden visual acuity on her right eye and anisocoria. She denied previous comorbidities and traumas. Upon examination, her ocular motility was normal and no ptosis was seen. Slit-lamp biomicroscopy and fundoscopy exams were normal. The mydriasis of the right eye, with consensual light reflex of ...

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.

An abnormal mydriasis of the pupil may be present after blunt contusion of the eye. Pro~ longed mydriasis indicates partial or complete rupture of the iris sphincter and may he permanent. 1 Anisocoria resulting from unilateral mydriasis may be associated with visual difficulties. Difficulties may be expected at nearwork because of the reduced depth of focus of the dilated eye. Other difficultie...

69 ABSTRACT PURPOSE: To report the incidence of anisocoria after unilateral excimer laser photorefractive kera-tectomy (PRK) for myopia and subsequent cortico-steroid therapy in a retrospective and prospective study and to explore possible etiologies. METHODS: The horizontal pupil diameter was determined in 6 patients (6 eyes) at 21.8 ± 12.6 months after unilateral wide-field excimer laser PRK ...

CASE REPORTS We present four cases: two males with Horner Syndrome, who were diagnosed by means of apraclonidine 0.5% and cocaine 4% tests respectively. Two children with anisocoria, one of whom had Horner Syndrome confirmed with apraclonidine 1% and the other, in whom an apraclonidine test ruled out this syndrome but in whom pilocarpine 0.125% confirmed Adie's pupil. DISCUSSION Apraclonidine...

1. Disorders of the iris sphincter that may require pharmacologic testing — cholinergic super-sensitivity vs. under-sensitivity: When evaluating an anisocoria that increases in bright light and decreases in dim light, attention usually shifts toward the pupil that is larger in bright light to determine if a paresis of the iris sphincter paresis is present. The causes are either from denervation...
