Abstract: Inflammatory glaucoma represents a complex interplay between ocular inflammation and elevated intraocular pressure (IOP), posing diagnostic and therapeutic challenges for ophthalmologists. This article provides a comprehensive review of inflammatory glaucoma, encompassing its pathophysiology, clinical presentation, diagnostic strategies, treatment modalities, and recent innovations. By delving into the nuances of this condition, ophthalmologists can optimize patient care and enhance outcomes in the management of inflammatory glaucoma.

Introduction: Inflammatory glaucoma, a subtype of secondary glaucoma, arises from inflammation-induced changes in aqueous dynamics and trabecular meshwork function. Understanding the underlying inflammatory processes and their impact on IOP regulation is crucial for effectively managing inflammatory glaucoma and preserving visual function.

Pathophysiology: Inflammatory glaucoma can result from various etiologies, including uveitis, ocular trauma, intraocular surgery, and autoimmune diseases. Inflammatory mediators released during ocular inflammation disrupt aqueous outflow pathways, leading to increased resistance within the trabecular meshwork and subsequent elevation of IOP. Chronic inflammation and tissue damage can further exacerbate glaucomatous optic neuropathy and visual field loss.

Clinical Presentation: Patients with inflammatory glaucoma may present with typical signs of elevated IOP, including optic disc cupping, visual field defects, and characteristic changes on anterior segment examination. Concurrent signs of intraocular inflammation, such as anterior chamber cells and flare, synechiae, and vitreous haze, may aid in distinguishing inflammatory glaucoma from other forms of secondary glaucoma.

Diagnostic Approaches: Diagnosis of inflammatory glaucoma involves a comprehensive assessment of ocular inflammation and IOP dynamics. Evaluation may include measurement of IOP, assessment of optic nerve morphology, visual field testing, anterior segment examination, and imaging modalities such as optical coherence tomography (OCT) and ultrasound biomicroscopy (UBM). Ancillary tests, including serological markers and inflammatory cytokine analysis, may be useful in identifying underlying inflammatory etiologies.

Treatment Strategies: Management of inflammatory glaucoma focuses on controlling intraocular inflammation, lowering IOP, and preserving visual function. Treatment modalities may include topical and/or systemic corticosteroids to suppress inflammation, antiglaucoma medications to reduce IOP, and immunomodulatory agents (e.g., methotrexate, cyclosporine) for refractory cases. Surgical interventions, such as trabeculectomy or glaucoma drainage devices, may be considered in cases of uncontrolled IOP or medication intolerance.

Recent Advances: Recent innovations in the management of inflammatory glaucoma aim to improve treatment efficacy, minimize side effects, and enhance patient outcomes. Advancements in targeted drug delivery systems, including sustained-release corticosteroid implants and biodegradable drug-eluting devices, offer prolonged anti-inflammatory effects while reducing treatment burden. Additionally, emerging biologic agents targeting specific inflammatory pathways hold promise for personalized and targeted therapy in inflammatory glaucoma.

Conclusion: Inflammatory glaucoma presents unique challenges in diagnosis and management, requiring a multidisciplinary approach and tailored treatment strategies. By staying informed about the latest research and innovations in inflammatory glaucoma, ophthalmologists can effectively address inflammation-induced changes in aqueous dynamics and optimize visual outcomes for affected patients.
