1/2. Postoperative endophthalmitis resulting from prosthesis contamination in a monocular patient.Monocular patients who wear an ocular prosthesis may harbor pathogenic conjunctival flora both in the socket and in the contralateral eye. They may therefore be at increased risk of developing endophthalmitis after intraocular procedures. We studied a monocular, prosthesis-wearing, 86-year-old man who underwent cataract extraction, subtotal transpupillary vitrectomy, and intraocular lens insertion. Fulminant endophthalmitis ensued postoperatively, and despite complete vitrectomy and administration of intraocular antibiotics, the eye lost light perception. Intravitreal as well as conjunctival cultures bilaterally grew proteus mirabilis. The patient disclosed that he cleaned the prosthesis frequently because of discharge. We considered an association between this bacterial colonization and the risk of developing postoperative endophthalmitis and suggest prophylactic measures for treatment of monocular patients undergoing intraocular procedures.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
2/2. Post-keratoplasty endophthalmitis caused by proteus mirabilis.A diabetic patient who underwent a triple procedure (penetrating keratoplasty, cataract extraction and posterior chamber intraocular lens implantation), developed endophthalmitis caused by proteus mirabilis. The source of infection was the infected donor cornea, which was imported from sri lanka. The organism was resistant to gentamicin, which was the only antibiotic present in the storage medium. On top of an aggressive antibiotic treatment regime (topical, systemic and intravitreal), exchange of the infected with a fresh corneal graft and pars plana vitrectomy were performed. The patient had a speedy recovery and the visual outcome was 20/40 two and a half years after the incident. To our knowledge, post-keratoplasty endophthalmitis caused by P. mirabilis has never been reported in the literature. We report herein such a case with good visual outcome. Newer storage medium, such as Optisol GS, might have a role in preventing keratoplasty-related infection.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
