Purpose: To examine the presentation and management of 3 cases of bleb-related infection following ab interno gel implant surgery, so as to add to the growing understanding of complications associated with the emerging landscape of newer, minimally invasive glaucoma surgical procedures, and how they are best managed.
Design: Multicenter retrospective interventional case series.
Methods: Consecutive cases of bleb-related infection following ab interno gel implant surgery from 2 university-affiliated hospitals were included. Risk factors, visual outcomes, intraocular pressure, and subsequent management were analyzed.
Results: We report 3 cases of late bleb-related infection occurring after ab interno gelatin stent insertion (8, 7, and 24 months after surgery). One case had blebitis only; the other 2 had bleb-related endophthalmitis. All cases responded rapidly to management of their infections according to standard bleb-related infection protocol, recovering to within 2 lines of their previous visual acuity (6/9, 6/12, and 6/18). Explantation of the devices was not required.
Conclusions: Bleb-related infections after ab interno gel implant insertion can occur. If infection is treated appropriately, good clinical outcomes are possible.

Article Synopsis
- North India experiences an annual outbreak of viral conjunctivitis during the monsoon season, impacting a large number of people, most of whom recover without treatment.
- Patients with a history of trabeculectomy (eye surgery for glaucoma) are at increased risk as conjunctivitis can lead to serious complications like blebitis and bacterial/fungal infections.
- It's crucial to educate these patients about the conjunctivitis outbreak and the warning signs that require immediate medical attention to prevent complications.

We describe a case of exogenous cryptococcal endophthalmitis without central nervous system (CNS) involvement or systemic infection in an immunocompetent patient. An 82-year-old male with hypertension, hyperlipidemia, type 2 diabetes mellitus, and primary open-angle glaucoma with a history of left eye trabeculectomy presented with 3 months of worsening left eye pain and redness. Vitreous cultures resulted as , prompting treatment with intravitreal amphotericin and further investigation.

species are Gram-negative coccobacilli that typically colonize the flora of the human upper respiratory tract and have low pathogenic potential. There are limited case reports implicating the organisms as the cause of endocarditis, bacteremia, septic arthritis, ocular infection, and meningitis. In cases of keratitis and conjunctivitis, is not commonly isolated from the ocular surface.

Background: Mitomycin C has been used adjunctively in various procedures, including pterygium excision. Delayed wound healing, the long-term complication of mitomycin C, can occur several years later and may rarely cause a subsequent inadvertent filtering bleb. However, conjunctival bleb formation from the reopening of an adjacent surgical wound after mitomycin C use has not been reported.
