Clinical Differences between Posner-Schlossman Syndrome Patients with Intermittent Intraocular Pressure Elevation and Glaucomatous Damage

INTRODUCTION: Although there is abundant evidence that Posner-Schlossman syndrome (PSS) can lead to secondary glaucoma, data on the clinical differences between PSS patients with secondary glaucoma and those with intermittent intraocular pressure (IOP) elevation are sparse. METHODS: This retrospecti...

Sumario:INTRODUCTION: Although there is abundant evidence that Posner-Schlossman syndrome (PSS) can lead to secondary glaucoma, data on the clinical differences between PSS patients with secondary glaucoma and those with intermittent intraocular pressure (IOP) elevation are sparse. METHODS: This retrospective observational study included 52 patients (52 eyes) diagnosed with PSS and admitted to Zhongnan Hospital of Wuhan University between January 2019 and February 2022. Demographic characteristics and clinical features were gathered from admission records. Patients were divided into two groups: 27 cases with intermittent IOP elevation (group A) and 25 cases with secondary glaucoma (group B and C). Of the secondary glaucoma cases, 18 were further divided into the topical IOP-lowering medications group (group B) and 7 into the glaucoma surgery group (group C). Clinical characteristics of different groups were compared. RESULTS: Compared to the intermittent IOP elevation group, PSS patients with secondary glaucoma had a longer course of disease, a higher incidence of iris depigmentation, lower best corrected visual acuity, lower endothelial cell density, and higher interferon-γ (IFN-γ) concentration and cytomegalovirus (CMV) deoxyribonucleic acid (DNA) copy number in the aqueous humor (all p < 0.05). Group C presented a higher CMV DNA copy number in the aqueous humor than groups A and B (p < 0.05). Compound trabeculectomy proved effective in group C, with a functional filter bleb and well-controlled IOP without disease progression after 1 year of follow-up. CONCLUSION: Distinctive characteristics existed between PSS patients with secondary glaucoma and those with intermittent IOP elevation. Compound trabeculectomy appears to be an effective treatment option when IOP cannot be controlled through topical medications.
