Isolated distichiasis is a rare condition in which an extra row of eyelashes grows from the eyelid margin. These extra eyelashes can cause irritation and discomfort, as well as a feeling of something in the eye. Treatment for isolated distichiasis typically involves the removal of the extra eyelashes.

The most common symptom of isolated distichiasis is the presence of extra eyelashes (known as distichiae) growing from the meibomian glands of the eyelid. These extra eyelashes can cause irritation, redness, and a feeling of something in the eye. Other symptoms may include:

-Excessive tearing

-Itching

-Blurred vision

-Light sensitivity

-Crusting of the eyelids

-Discomfort when blinking

Isolated distichiasis is caused by an abnormal growth of eyelashes from the meibomian glands, which are located in the eyelids. It can be caused by genetics, trauma, or inflammation. Other possible causes include hormonal imbalances, certain medications, and certain medical conditions.

1. Manual epilation: This involves the use of tweezers to remove the extra eyelashes one by one.

2. Cryotherapy: This involves freezing the extra eyelashes with liquid nitrogen.

3. Laser ablation: This involves using a laser to destroy the extra eyelashes.

4. Electrolysis: This involves using an electric current to destroy the extra eyelashes.

5. Intense pulsed light therapy: This involves using a light source to destroy the extra eyelashes.

The risk factors for Isolated distichiasis include:

1. Age: It is more common in adults than in children.

2. Gender: It is more common in women than in men.

3. Genetics: It is more common in people with a family history of the condition.

4. Certain medical conditions: People with certain medical conditions, such as diabetes, thyroid disease, and autoimmune disorders, may be at an increased risk of developing Isolated distichiasis.

5. Certain medications: Certain medications, such as isotretinoin, may increase the risk of developing Isolated distichiasis.

Isolated distichiasis is a rare condition that is usually treated with surgery. In some cases, medications such as topical steroids or antibiotics may be prescribed to reduce inflammation and infection. In more severe cases, laser therapy may be used to remove the extra eyelashes.
