Panophthalmitis With Orbital Cellulitis Following Glaucoma Drainage Implant Surgery in an Adult Patient.
Article in The American journal of case reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
BACKGROUND Glaucoma drainage implants, including the Paul glaucoma implant, are widely used in the management of refractory glaucoma when medical therapy and conventional filtering surgery prove insufficient. Although associated with favorable outcomes, rare but serious postoperative complications such as endophthalmitis and panophthalmitis can occur, resulting in significant visual morbidity. CASE REPORT We describe the case of a 77-year-old man with chronic angle-closure glaucoma who developed acute panophthalmitis with orbital cellulitis 12 days following uneventful Paul glaucoma implant surgery. He presented with severe ocular pain, eyelid swelling, restricted ocular motility, and marked reduction in visual acuity to light perception. Clinical examination revealed pronounced anterior and posterior segment inflammation. B-scan ultrasonography showed dense vitreous opacities, shallow choroidal detachment, and ocular wall thickening. Computed tomography of the orbit confirmed associated orbital cellulitis with proptosis and extraocular muscle swelling. The patient underwent vitreous tap with intravitreal vancomycin, ceftazidime, and dexamethasone, along with intensive topical and systemic antimicrobial therapy. Despite an initial partial response, progressive inflammation required pars plana vitrectomy. Removal of the glaucoma drainage implant was not possible intraoperatively due to severe inflammation. Microbiological cultures remained negative throughout. With coordinated multidisciplinary management involving glaucoma, retina, and oculoplastic services, orbital inflammation gradually resolved, and visual acuity improved from light perception to 20/250 at final follow-up. CONCLUSIONS This case highlights the importance of close postoperative monitoring to ensure correct diagnosis and aggressive management of infections, preservation of globe integrity, and optimization of visual outcomes following glaucoma drainage device surgery.
