Peptostreptococcal endophthalmitis with a relapsing course.

A posttraumatic exogenous endophthalmitis developed that was due to Peptostreptococcus. This Gram-positive anaerobe was isolated in pure culture from vitreous. The endophthalmitis showed a bacteriologic and clinical relapse despite conventional routes of antimicrobial treatment. A second clinical relapse occurred despite apparent vitreal sterilization with intravitreal antibiotics. The response to vitrectomy was impressive, and postoperatively the patient's visual acuity improved to 20/20.

Traumatic endophthalmitis caused by an Erwinia species.

A previously healthy 70-year-old white man sustained a plant injury to his left eye while gardening and was admitted here because of an ensuing perforated cornea and endophthalmitis. The lens was opaque and its anterior capsule was ruptured. Culture of fluid obtained by anterior chamber paracentesis yielded a species of the Erwinia herbicolalathyri group (Enterobacter agglomerans). Thirty-seven days after a course of cefazolin and gentamicin therapy, corneal edema necessitated a planned extracapsular cataract extraction. The aqueous humor and lens again revealed the identical Erwinia species in pure culture. The patient received another course of cefazolin and showed improvement after the lens aspiration.

Staphyloma: a complication of surgery for hyphema.

Anterior staphylomas developed in two young patients as a postoperative complication of hyphema extractions through corneoscleral sections. The patients, aged five and nine years, underwent evacuation of the hyphemas after rebleeding caused medically unmanageable intraocular pressure elevations. Postoperatively, both patients received corticosteroids and had elevation of intraocular pressure. To repair the staphyloma, a scleral overlay patch graft was performed in one patient, but the intraocular pressure remained elevated and the staphyloma gradually recurred. Enucleation of the eye was eventually required. Resection of the staphylomatous area with lensectomy and complete vitrectomy was performed in the second patient. After four years of follow-up this patient continues to do well.
