ABSTRACT
Purpose: Ocular manifestations in psoriasis are due to direct eye involvement with psoriatic plaques or psoriasis?related, immune?mediated inflammatory processes. The commonly reported pathologies are blepharitis, conjunctivitis, keratitis, dry eyes, and uveitis. Limited data is available on the ocular findings in psoriasis patients in India. In this study, we evaluated various ocular changes associated with moderate-to-severe psoriasis. Methods: In this prospective cohort study, treatment?naive psoriasis patients with Psoriasis Area Severity Index (PASI) score of more than 10 were included. The Ocular Surface Disease Index (OSDI) score, Schirmer’s score, tear film breakup time (TBUT), corneal and conjunctival staining score, and meibomian gland dysfunction score were noted. All these parameters were re?evaluated at 8 weeks of follow?up after systemic treatment. Results: Sixty-eight patients were enrolled in the study. The most common ocular pathologies observed in this study were tarsal hyperemia and anterior blepharitis in 128 (94.1%) and 64 (47%) eyes, respectively. Mild, moderate, and severe dry eyes were seen in 26 (19.1%), 14 (10.2%), and 34 (25%) eyes, respectively. Thirty?nine (57.3%) patients complained of significant difficulty watching television or digital screen. In 21 patients evaluated on follow?up at 8 weeks, cornea and conjunctiva’s ocular surface staining score increased and TBUT decreased significantly. Conclusion: The most common ocular pathologies observed in this study were anterior blepharitis and moderate dry eye, which significantly affected most patients’ daily routines. Screening patients with greater severity of psoriasis would help in early management of such problems.
