Clinical profile and demographic distribution of band shaped keratopathy in India: A study of 8801 patients

ABSTRACT

Purpose: To describe the clinical profile and demographic distribution of band?shaped keratopathy (BSK) in patients presenting to a multitier ophthalmology hospital network in India. Methods: This cross?sectional hospital?based study included 2,664,906 new patients presenting between January 2011 and January 2021 (10?year period). Patients with a clinical diagnosis of BSK in at least one eye were included as cases. The data were collected using an electronic medical record system. Results: Overall, 8801 (0.33%) patients were diagnosed with BSK. The prevalence rates were 0.47% in children (age <16 years) and 0.31% in adults. The majority of patients were males (62.87%) with unilateral affliction (85.21%). The mean age of the patients was 40.43 ± 23.14 years. The majority (16.93%) of the patients were in the age bracket of 11–20 years. A larger proportion of the patients were from higher socioeconomic status (60.46%) and the urban region (45.9%). Of the 10,103 eyes affected with BSK, the common ocular comorbidities were status post?vitreoretinal surgery (20.55%) and uveitis (12.7%) in children and corneal scar (41.23%) and spheroidal degeneration (13.7%) in adults. Most of the eyes had mild or no visual impairment (24.74%). Among the eyes that needed surgical intervention, chelation with ethylenediaminetetraacetic acid (EDTA) was the most performed surgical procedure (1.68%) along with phototherapeutic keratectomy (0.32%). Conclusion: BSK commonly affects adult males and is unilateral in nature. The majority of the patients in this cohort belonged to higher socioeconomic strata and urban geography. At initial presentation, visual impairment was mild to moderate in a vast majority of the patients, and the most common surgical intervention performed was chelation with EDTA during the study period.
