ICD-10: B87.2

Ocular myiasis, classified under ICD-10 code B87.2, refers to a parasitic infestation of the eye by larvae of certain fly species. This condition is a specific type of myiasis, which generally involves the invasion of tissues by fly larvae. Here’s a detailed overview of ocular myiasis, including its clinical description, causes, symptoms, diagnosis, and treatment options.

Clinical Description

Definition

Ocular myiasis is characterized by the presence of fly larvae in the conjunctival sac or other parts of the eye. It can lead to significant discomfort and potential complications if not treated promptly. The condition is most commonly associated with the larvae of the Oestrus ovis (sheep botfly) and Cordylobia anthropophaga (tumbu fly), among others.

Epidemiology

Ocular myiasis is more prevalent in tropical and subtropical regions where these flies are endemic. It can occur in both humans and animals, with cases reported in various geographical locations, particularly in rural areas where livestock is present.

Causes

Ocular myiasis is primarily caused by the accidental or intentional introduction of fly larvae into the eye. This can occur through:

• Direct contact: Flies may lay eggs near the eyes, and the larvae can migrate into the ocular area.
• Environmental exposure: Individuals in close proximity to infested animals or contaminated environments are at higher risk.

Symptoms

The symptoms of ocular myiasis can vary depending on the severity of the infestation but typically include:

• Eye irritation: Patients often report a sensation of something foreign in the eye.
• Redness and swelling: Inflammation of the conjunctiva may occur.
• Discharge: Purulent or serous discharge can be present.
• Visual disturbances: In severe cases, vision may be affected if the cornea or other ocular structures are involved.

Diagnosis

Diagnosis of ocular myiasis is primarily clinical, based on the history of exposure and the presence of larvae in the eye. Key diagnostic steps include:

• Clinical examination: An ophthalmologist will perform a thorough examination of the eye using a slit lamp to identify the larvae.
• History taking: Understanding the patient's exposure to flies or infested environments can aid in diagnosis.

Treatment

Treatment for ocular myiasis involves the removal of the larvae and managing any associated symptoms. Common approaches include:

• Mechanical removal: An ophthalmologist may use forceps or other instruments to extract the larvae from the eye.
• Topical medications: Antibiotic or anti-inflammatory eye drops may be prescribed to manage infection and inflammation.
• Preventive measures: Educating patients about avoiding exposure to flies and maintaining good hygiene can help prevent future occurrences.
