Abstract
Psoriasis is a chronic systemic disorder with ocular involvement. To evaluate the risk of glaucoma among patients with psoriasis. Participants in this cohort study were selected based on Chang Gung Research Database from 1 January 2003 to 31 December 2012. Follow-up ended on 31 December 2017. The participants in the control group were matched with the psoriasis group by sex, age and index date with a 4 : 1 ratio. The hazard ratios of glaucoma were estimated using Cox regression analysis. We also evaluated the relationship between the risk of glaucoma and systemic therapies as well as phototherapy and topical corticosteroid in patients with psoriasis. In total, 6682 patients with psoriasis and 26 728 matched controls were enrolled. The study population was composed mainly of males accounting for 64.2% (21 445/33 410) of the study population. The psoriasis group had higher incidence rates than the control group for glaucoma (adjusted hazard ratio 1.405, 95% confidence interval, 1.051-1.879). Patients with psoriasis receiving psoralen-ultraviolet A (PUVA) therapy for > 200 sessions had an increased risk of glaucoma. Patients with psoriasis had an increased risk of glaucoma. Long-term PUVA therapy raised the risk of glaucoma in people with psoriasis.
