Ab Interno Ahmed Glaucoma Valve Plugs In An Eye With Persistent Hypotony.

PURPOSE: This case report aims to describe a new method for increasing intraocular pressure (IOP) in patients with acute hypotony resulting from uveitis flare-ups and preexisting glaucoma drainage devices. The temporary glaucoma tube plug method described is effective and safe. METHODS: This case report presents a 47-year-old female patient with a history of chronic panuveitis and secondary glaucoma, who had 2 previously implanted Ahmed glaucoma valves. The patient developed panuveitis flare-up and persistent hypotony. A novel method of ab interno plugging of the glaucoma tubes using 2-0 prolene suture plugs was performed. Following treatment, the IOP increased successfully and remained within the normal range. CONCLUSION: The temporary ab interno glaucoma tube plug method effectively increased IOP in a patient with 2 preimplanted Ahmed glaucoma valves with persistent low IOP due to uveitis.

Surgically Induced Scleritis Associated With Suture Hypersensitivity Following Strabismus Surgery.

A 67-year-old woman with history of mild suture hyper-sensitivity presented with localized scleritis after strabismus surgery. After infection was ruled out, the patient was prescribed topical and systemic non-steroidal anti-inflammatory drugs and systemic steroids, which led to full clinical resolution.

Rahnella Aquatilis Endophthalmitis after Intravitreal Injection in an Immunocompetent Patient.

PURPOSE: To present a novel case of exogenous Rahnella aquatilis endophthalmitis following an intravitreal injection. METHODS: Case report. RESULTS: A 74-year-old male presented with acute progressive vision loss and pain in the left eye, 5 days after an intravitreal injection for diabetic macular edema. The patient was diagnosed with exogenous endophthalmitis and empirically treated with intravitreal injections of vancomycin and ceftazidime as well as topical and oral ciprofloxacin. In follow up two days later, the patient was treated with preoperative povidone-iodine followed by prompt vitrectomy with additional vancomycin and ceftazidime due to pharmacy sterile hood issues that delayed antibiotic availability. Microbiological cultures and two mass spectrometry identification tests confirmed the diagnosis of exogenous Rahnella aquatilis endophthalmitis. Despite the presence of scattered retinal hemorrhagic infarcts involving the macula and subsequent full-thickness atrophic macular holes seen in follow up, the patient achieved a favorable anatomical and functional outcome of BCVA 20/80 at 1 year of follow-up. CONCLUSION: This case highlights the occurrence of exogenous Rahnella aquatilis endophthalmitis following an intravitreal injection for diabetic macular edema. Prompt diagnosis and treatment produced a favorable outcome relative to other typical Gram-negative Enterobacteriaceae organisms.
