To present the clinical features, management, and outcomes of 4 cases of bee sting injury to the cornea and conjunctiva. ⋯ Ocular surface bee stings with retained stingers are rarely reported. A potential triad of penetrating, immunologic, and toxic injury must be taken into consideration. Vision can be restored by early removal of the sting and topical medication.
-
To report the diagnosis and management of a patient with chronic ophthalmic topical anesthetic abuse and floppy eyelid syndrome. ⋯ Uncommon conditions may coexist in 1 patient. In this case, floppy eyelid syndrome resulted in topical anesthetic abuse. Ophthalmologists should keep both these conditions in mind when treating patients with otherwise unexplained chronic persistent corneal erosions.

Spontaneous corneal perforation during acute hydrops in keratoconus is a very rare complication and has only been described in patients with advanced keratoconus. We describe a case of spontaneous corneal perforation in mild keratoconus in a patient with no identifiable risk factors. ⋯ To our knowledge, this is the first reported case of spontaneous perforation of the cornea in mild keratoconus. We demonstrate that in this event, a good visual prognosis is possible from gluing alone.

Multicenter Study
Changing indications for penetrating keratoplasty in Greece, 1982-2006: a multicenter study.
To evaluate the leading indications for penetrating keratoplasty (PKP) and their trends in Greece during the period 1982 to 2006. ⋯ Aphakic/pseudophakic corneal edema was the most common indication for PKP in a multicenter series in Greece followed by keratoconus. The number of regrafts dramatically increased during the 25-year period.

The purposes of this study were to report the indications, graft survival, risk factors for graft failure, and visual outcomes for third or greater penetrating keratoplasties (PKP). ⋯ Over 50% of third and fourth grafts were clear at 5 years postoperatively. Outcomes of third grafts were better in patients with Fuchs dystrophy, keratoconus, and herpetic keratitis. Absence of previous glaucoma surgery and/or corneal neovascularization is associated with better outcomes of multiple PKPs.
