Cutaneous larva migrans with optic disc edema: a case report.

Introduction: A rare case of optic disc edema associated with cutaneous larva migrans is presented. To the best of our knowledge, this has not been previously reported in literature. Joint management by ophthalmology and tropical medicine teams proved most beneficial for our patient, facilitating correct diagnosis, appropriate investigations and instigation of suitable treatment.

Unilateral optic disc pit and orbital cyst in an eye with normal axial length.

Orbital cyst and optic disc pits are both congenital embryological anomalies. Orbital cysts occurring in association with optic disc colobomata and microphthalmic eyes have been widely reported in literature. The authors describe the case of a 69-year-old man with an asymptomatic orbital mass, who was investigated and found to have a coexistent optic disc pit and orbital cyst.

Persistent fetal vasculature and spontaneous hyphema in a patient with Klippel-Trénaunay-Weber syndrome.

Klippel-Trénaunay-Weber syndrome is characterized by the triad of capillary malformations (usually port-wine stains), varicose veins or venous malformations of unusual distribution, and soft-tissue or bony hypertrophy of an extremity. The syndrome can be diagnosed on the basis of 2 of these 3 features. In the atypical form of the syndrome, capillary malformations may be absent.

Effect of cataract surgery and pupil dilation on iris pattern recognition for personal authentication.

Purpose: The purpose of this study was to investigate the effect of cataract surgery and pupil dilation on iris pattern recognition for personal authentication.

Methods: Prospective non-comparative cohort study. Images of 15 subjects were captured before (enrolment), and 5, 10, and 15 min after instillation of mydriatics before routine cataract surgery.
