B87.2
Ocular myiasis
Clinical Classification Guidelines
Medical Intelligence & Overview
Ocular myiasis is a rare condition characterized by the infestation of the eye by fly larvae, also known as maggots. This condition can affect various parts of the eye, including the eyelids, conjunctiva, and, in severe cases, the interior eye structures. Recognized under the ICD-10 code B87.2, ocular myiasis is typically associated with certain environmental and health factors, and it requires prompt attention to prevent potential vision impairment.
Causes & Symptoms
Clinical Causes: Contamination of the eye with fly eggs or larvae in environments where flies are prevalent. Exposure to infested water or soil containing fly larvae. Poor hygiene or living conditions in areas with high fly populations. Inadequate protection of the eyes during outdoor activities in rural or tropical regions. Presence of open wounds or ocular trauma that attracts flies seeking a site to deposit eggs.
Key Symptoms: Redness and swelling of the eyelids or conjunctiva. Itching or a sensation of movement within the eye. Discharge from the eye, which may be clear, mucous, or purulent. Pain or discomfort in or around the eye. Visible movement of larvae within the conjunctiva or on the eyelids. Blurred vision or a feeling of foreign body sensation. In severe cases, swelling and tissue damage affecting eye function.
Diagnostic & Treatment
Diagnosis Path: Diagnosis typically involves a thorough eye examination, where healthcare providers look for signs of larvae or maggots within or around the eye tissues. The presence of moving larvae is usually confirmatory. Ancillary tests are rarely needed but may include slit-lamp microscopy for detailed visualization, and, in some cases, laboratory identification of extracted larvae to confirm infestation type.
Treatment Protocols: Management of ocular myiasis involves careful removal of the larvae, usually performed under local anesthesia to ensure patient comfort. Techniques may include use of specialized instruments or manual extraction with forceps. Following removal, thorough cleaning of the ocular surface is essential, and appropriate measures are taken to prevent secondary infections, which may include antibiotic eye drops or ointments. In some instances, surgical intervention may be necessary if tissue damage is extensive. Post-treatment, close monitoring is necessary to ensure healing and to detect any recurrence. Preventive steps include maintaining good personal and environmental hygiene, protecting the eyes from contact with infested environments, and prompt treatment of ocular injuries or infections.
