Purpose
Aim is to show the application of ethylenediaminetetraacetic acid (EDTA) in the treatment of calcific band keratopathy. Calcific band keratopathy is a corneal degeneration that is characterized by subepithelial deposition of calcium, primarily in the form of hydroxyapatite, in the epithelial basement membrane, Bowman's layer, and the anterior stroma. Patients with calcific band keratopathy have decreased vision but are typically asymptomatic. Mild ocular irritation can be managed with lubricating drops and gels, moderate to severe irritation can be managed conservatively with a bandage soft contact lens.
Setting
Department of ophthalmology, University Hospital Dubrava Zagreb.
Methods
Manual dissection and removal of calcific deposits with EDTA chemical chelation to facilitate more complete removal of the calcium deposits has been the treatment of choice for symptomatic band keratopathy.
Results
A 37-year-old patient with a diagnosis of chronic herpes simplex kerato-uveitis lasting for 5 years is presented with calcific band keratopathy with decreased vision. Preoperative visual acuity was logMar 0.7, and one month after treatment logMar 0.2
Conclusions
The treatment of choice for calcific band keratopathy is manual dissection and removal of calcific deposits with EDTA chemical chelation. Procedure is simple, low cost and very beneficial for patients’ vision.
