Insights
Band keratopathy, a corneal degeneration, can occur years after diode laser treatment for retinopathy of prematurity. This complication may be underrecognized in children without other known risk factors.
Area of Science:
- Ophthalmology
- Corneal Diseases
- Pediatric Ophthalmology
Background:
- Band keratopathy is a corneal degeneration characterized by calcium hydroxyapatite deposition in Bowman's layer.
- Etiologies include chronic inflammation, systemic conditions, and rare genetic mutations (SLC4A4).
- Retinopathy of prematurity (ROP) is a leading cause of childhood blindness.
Purpose of the Study:
- To investigate the association between diode laser treatment for ROP and the development of late-onset band keratopathy.
- To identify risk factors and clinical characteristics of band keratopathy in this specific pediatric population.
Main Methods:
- Retrospective case series analysis.
- Review of clinical records for 10 children (16 eyes) with a history of diode laser-treated ROP.
- Ophthalmic examination, including slit-lamp biomicroscopy and assessment of visual acuity.
Main Results:
- 10 children (16 eyes) developed late-onset band keratopathy after diode laser treatment for ROP.
- No other risk factors for band keratopathy were identified in these patients.
- The majority of cases were bilateral, with five eyes requiring intervention (EDTA chelation or phototherapeutic keratectomy) for visually significant central deposits.
Conclusions:
- Band keratopathy may be an underreported ophthalmic complication following diode laser treatment for ROP in children.
- Ophthalmologists should consider this association in pediatric patients presenting with band keratopathy, especially those with a history of ROP treatment.
- Further research is warranted to elucidate the pathophysiology and long-term implications.
Abstract:
Band keratopathy is a corneal degeneration caused by chronic inflammation, systemic abnormalities, or, rarely, a primary biallelic SLC4A4 mutation leading to calcium hydroxyapatite deposition in Bowman's layer. We report a series of 16 eyes of 10 children with a remote history of diode laser treated retinopathy of prematurity who developed late-onset band keratopathy without evidence of other prior risk factors. The majority of patients developed band keratopathy bilaterally. Five eyes had visually significant central band keratopathy that required treatment with disodium ethylenediaminetetracetic acid (EDTA) chelation or phototherapeutic keratectomy. Band keratopathy may be an underreported late ophthalmic complication of diode-laser treated retinopathy of prematurity.
