Abstract Details

Purpose:

Conjunctival concretions are a common and usually easily solved condition. Chronic conjuntival inflamation and abusive contact lens use are among the most common causes. Corneal lesions are one of the most common complications. Altough contact lens can be sometimes the cause, they can also be used as protective to the corneal epithelium. The authors present a case of exuberant and recurrent conjunctival concretion that required a adjunctive treatment with ethylenediamine tetra acetic acid (EDTA).

Setting:

Corneal Diseases Department, Institute of Ophthalmology Dr. Gama Pinto, Lisbon, Portugal

Methods:

Case report

Results:

Female patient, 51 years old, long-term contact lens user, presenting in the last five years with chronic foreign body sensation and lacrimation in both eyes upon removal of the contact lenses. Multiple, giant, confluent and recurrent conjuntival calcific concretions at both superior eyelids were already diagnosed and removed at the slit-lamp more than 15 times, with rapid recurrences. When presenting to our department, the concretions had evolved to confluent plaques that caused corneal erosions that precluded from stoping the contact lens use. Calcium-phosphorus metabolism disorders were investigated and surgical removal with EDTA chelation was proposed and done.

Conclusions:

Conjunctival concrections are usually seen as a minor disorder, conventionally solved at the-slit-lamp. However, very atypical and exuberating cases causing intolerable symptoms as the one presented may require different aproaches. EDTA chelation can be used as an intra-operative adjunctive therapy.
