ABSTRACT
PURPOSE: To study clinical characteristics and management outcomes of cases of ocular syphilis co-presenting with scleritis and active uveitis. METHODS: A retrospective analysis of cases diagnosed with ocular syphilis between January 2020 and December 2023 was conducted at a tertiary eye care centre. Clinical records, investigations, and outcomes were reviewed to identify cases with scleritis with active uveitis. Demographic data, clinical features, treatment modalities, and resolution patterns were analyzed. RESULTS: Among the 135 eyes of 95 cases of ocular syphilis studied, scleritis with uveitis was observed in 3.70% of eyes (five eyes). All cases with scleritis and uveitis were unilateral and male, with ages ranging from 32 to 61 years. Concurrent features included placoid chorioretinitis, retinal vasculitis, and anterior uveitis. Misdiagnosis with subsequent oral steroid therapy precipitated scleritis as an exacerbation in two cases. Three cases, which were previously undiagnosed, were found to be HIV-positive. Scleritis manifested as anterior, non-necrotizing inflammation, often accompanied by chemosis, and responded rapidly to antibiotic and non-steroidal anti-inflammatory therapy. Scleritis resolution preceded that of chorioretinitis and retinal vasculitis. CONCLUSIONS: Non-necrotizing anterior scleritis with chemosis can be a rare presentation of active syphilitic uveitis. Large placoid chorioretinitis lesions, preceding inadvertent oral steroid and/or undiagnosed HIV status were the possible risk factors for the development of concurrent scleritis.
