Purpose:

To evaluate the prevalence of various etiologies of pediatric and adult band keratopathy at one tertiary referral center, and to assess the frequency of relevant comorbidities.

Methods:

After Institutional Review Board (IRB) approval, data were collected retrospectively. Adult subjects were identified by searching the electronic medical record (EMR) at our institution for the Current Procedural Terminology (CPT) code for removal of corneal epithelium with application of chelating agent (e.g. EDTA) and the International Classification of Diseases (ICD-10) codes for band keratopathy (BK). Pediatric subjects were identified by searching for ICD-10 codes for BK. Exclusion criteria included lack of definitive BK diagnosis, insufficient information available in the EMR, and presentation predating the EMR or after July 2020. 23 children and 49 adults met criteria.

Results:

49 adult patients and 64 eyes were identified. 31% had bilateral BK with ages ranging from 20-96 years old (mean 62.95±19.67). 55% were female, 45% male. 7 adult patients (14%) had trauma listed for etiology. 5 patients (10%) had silicone oil for etiology. 7 adults (14%) had a multifactorial etiology, and 15 (31%) had an undetermined etiology as documented in the EMR. 23 pediatric patients and 37 eyes were identified. 61% had bilateral BK with ages ranging from 1-16 years old (mean 11.18±4.12). 11 patients (48%) had BK due to panretinal photocoagulation and cryotherapy for retinopathy of prematurity.

Conclusions:

Most adult patients had an etiology that was undetermined or multifactorial, while most pediatric patients had an etiology from treatment of ROP. Knowledge of etiologies may help providers identify patients at greater risk and determine which patients may benefit from further therapy.
