Ocular dirofilariasis is a rare parasitic disease caused by nematodes of the genus Dirofilaria. The infection can be transmitted through mosquito bites that carry the parasite larvae. Recognizing ocular dirofilariasis can be challenging, as symptoms may resemble other ophthalmic conditions. Here are the main signs and symptoms that may indicate ocular dirofilariasis.

MAIN SYMPTOMS

1. Redness and swelling:

The infected eye may become red and swollen.
Inflammation of the eyelids and conjunctiva may occur.
2. Pain and discomfort:

Patients may experience pain, itching, or burning in the eyes.
A sensation of a foreign body in the eye.
3. Movable mass:

One of the characteristic signs is the presence of a movable mass under the skin of the eyelids or conjunctiva. This mass can move as the parasite actively migrates under the skin.
4. Blurred vision:

In some cases, there may be complaints of temporary vision impairment or blurriness.
5. Tearing and discharge:

Tearing and mucopurulent discharge from the eyes may be observed.
DIAGNOSIS

If you suspect ocular dirofilariasis, it is important to consult an ophthalmologist. The doctor may perform the following diagnostic procedures:

VISUAL EXAMINATION:

The ophthalmologist will conduct a thorough eye examination using a slit lamp to detect any movable mass or inflammation.
EYE ULTRASOUND:

Ultrasound examination helps visualize the parasite within the eye structures.
BIOMICROSCOPY:

This method is used for a detailed examination of the anterior segment of the eye.
LABORATORY TESTS:

In some cases, laboratory analysis of tissue samples or discharges may be required to confirm the presence of the parasite.
TREATMENT

Treatment of ocular dirofilariasis usually requires surgical removal of the parasite. The ophthalmologist may perform a minor surgery under local anesthesia to extract the nematode. After the removal of the parasite, anti-inflammatory and antibacterial medications may be prescribed to prevent secondary infection and reduce inflammation.

PREVENTION

To prevent dirofilariasis, it is important to avoid mosquito bites, especially in endemic areas. Use repellents, wear protective clothing, and install window screens to reduce contact with mosquitoes.

Early consultation with a doctor and timely diagnosis are key to the successful treatment of ocular dirofilariasis. If you suspect this disease, do not delay visiting an ophthalmologist.
