Capnocytophaga keratitis.
We report two cases of bacterial keratitis caused by Capnocytophaga, a genus of capnophilic Gram negative bacilli. Both responded to topical and subconjunctival clindamycin.

Fuchs's heterochromic cyclitis and posterior capsulotomy.
We report a case of intractable glaucoma following an uncomplicated secondary posterior capsulotomy in a 48-year-old male with Fuchs's heterochromic cyclitis. The patient had been free of inflammation and glaucoma since cataract extraction 27 years previously. We also report the results of phenotypic analysis of lymphocytes removed from the anterior chamber.

Gonococcal keratoconjunctivitis.
Gonococcal keratoconjunctivitis is a potentially devastating infection, because Neisseria gonorrhoeae can cause a rapid, severe, ulcerative keratitis resulting in visual loss. The therapeutic decision making process is complicated by the necessity for prompt, effective parenteral therapy, frequent coinfection with other sexually transmitted diseases, and emergence of antibiotic resistance. Because of the evolving problem of antibiotic resistance and the need for cost containment, the current recommendations of hospitalization for intravenous penicillin may need to be modified. The third generation cephalosporin, ceftriaxone, has properties that suggest it may be the best available antimicrobial agent as a single-dose treatment of gonococcal conjunctivitis. Spectinomycin may be a useful alternative in the penicillin-allergic adult patient.

Acanthamoebic keratitis in a healthy Australian man.
We report a case of acanthamoebic keratitis that occurred after minor ocular trauma in a healthy 31-year-old man. Multiple microbiological investigations failed to reveal the causative organism, which was identified as Acanthamoeba castellanii only after a corneal graft operation had been performed. A review of previously described cases reveals that this rare ocular infection tends to cause recalcitrant corneal ulcers after minor eye injuries in otherwise healthy individuals.
