Abstract: Secondary open-angle glaucoma (SOAG) encompasses a diverse group of ocular conditions characterized by elevated intraocular pressure (IOP) and optic nerve damage, despite a patent iridocorneal angle. This article provides a comprehensive review of SOAG, exploring its various etiologies, clinical manifestations, diagnostic criteria, treatment modalities, and recent advancements. By delving into the complexities of SOAG, ophthalmologists can refine their approach to patient care and improve outcomes in this challenging condition.

Introduction: Secondary open-angle glaucoma poses diagnostic and therapeutic challenges in ophthalmology, often arising as a consequence of underlying ocular or systemic conditions. Understanding the diverse etiologies and pathophysiological mechanisms of SOAG is essential for accurate diagnosis and appropriate management.

Etiologies: SOAG can arise secondary to a wide range of ocular and systemic conditions, including pseudoexfoliation syndrome, pigment dispersion syndrome, uveitis, steroid-induced glaucoma, and trauma, among others. Each etiology presents unique challenges in diagnosis and management, requiring a tailored approach to patient care.

Clinical Manifestations: Patients with SOAG may present with symptoms similar to primary open-angle glaucoma, including gradual peripheral vision loss, optic nerve cupping, and elevated IOP on examination. However, identification of underlying etiologies and associated clinical features is essential for guiding treatment decisions and optimizing outcomes.

Diagnostic Criteria: Diagnosis of SOAG requires a comprehensive ocular examination, including measurement of IOP, assessment of optic nerve morphology, visual field testing, and evaluation of angle structures. Ancillary tests such as gonioscopy, optical coherence tomography (OCT), and ultrasound biomicroscopy (UBM) may aid in identifying underlying etiologies and guiding treatment strategies.

Management Strategies: Management of SOAG aims to lower IOP, preserve optic nerve function, and maintain visual function through a combination of medical, laser, and surgical interventions. Treatment modalities may include topical ocular hypotensive medications, laser trabeculoplasty, and surgical interventions such as trabeculectomy or glaucoma drainage devices, tailored to the specific etiology and severity of the disease.

Recent Advances: Recent innovations in SOAG management focus on optimizing diagnostic techniques, enhancing treatment efficacy, and minimizing treatment-related complications. Advancements such as targeted pharmacotherapy, minimally invasive glaucoma surgery (MIGS) techniques, and personalized treatment algorithms offer potential benefits in achieving IOP control and preserving visual function in individuals with SOAG.

Conclusion: Secondary open-angle glaucoma represents a diverse spectrum of ocular conditions with significant implications for visual health. By staying informed about the latest research and innovations in SOAG management, ophthalmologists can optimize patient outcomes and improve quality of life for individuals affected by this condition.
