Conjunctival keratoacanthoma.

Keratoacanthoma generally occurs on the skin; it is rarely found in the conjunctiva. A case of a 34-year-old woman with a rapidly growing conjunctival mass is reported. The tumor was excised with a safety margin to exclude squamous cell carcinoma. Histopathologically it was crateriform and consistent with atypical keratoacanthoma. There has been no recurrence in 2 years of follow-up. Conjunctival keratoacanthoma is rare; differential diagnosis of conventional squamous cell carcinoma and keratoacanthoma can be difficult. We recommend complete surgical excision and careful follow-up of crateriform squamous proliferations.

Endophthalmitis caused by Agrobacterium radiobacter.

Infections due to Agrobacterium radiobacter are rare. This study reports 2 cases of A. radiobacter endophthalmitis. To the authors' knowledge, these are only the second and third reported cases of endophthalmitis caused by this Gram-negative rod.

Prognostic factors in open globe injuries.

PURPOSES: To evaluate the main factors related to visual outcome after open globe injuries (excluding intraocular foreign bodies). METHODS: Retrospective study analyzing consecutive ocular lacerations, primarily repaired in this institution, between January 1993 and January 2000. Of the 364 cases, 283 (77.75%) lacerations were statistically analyzed, correlating the preoperative variables with the postoperative visual acuity (VA). Excluded from this study were all patients with less than 6 months of follow-up, previous ocular surgery, unreliable information on VA, intraocular foreign bodies and endophthalmitis. When a bilateral injury was detected, only 1 eye was randomly chosen. RESULTS: It was observed, after statistical analysis (multivariate analysis), that the most important factors related to postoperative poor VA (less than 20/100) were: the length of the laceration, the elapsed time between the injury and the surgery and the presence or absence of vitreous loss, cataract (lens damage), hyphema, laceration posterior to rectus muscle insertion and retinal detachment. CONCLUSION: With this study, it was possible to point out the most important factors related to visual prognosis in open globe injuries. The results found are similar to results previously reported.
