Aden ulcer is a term used in medical terminology to describe a specific type of ocular surface disorder known as Mooren's ulcer. Mooren's ulcer is a rare, painful, and progressive condition that affects the cornea, which is the clear front surface of the eye. It is characterized by the presence of a non-inflammatory ulceration or erosion on the peripheral cornea.
The term "Aden ulcer" specifically refers to a variant of Mooren's ulcer that was first described in the Aden region of Yemen. It is often used to differentiate this particular subtype from other forms of Mooren's ulcer.
Aden ulcers typically occur in adults over the age of 40 and are more common in males. The exact cause of these ulcers is unknown, but it is believed to involve an abnormal immune response and a disruption of the normal healing process in the cornea.
Symptoms of Aden ulcer may include severe eye pain, redness, photophobia (sensitivity to light), tearing, and blurred vision. If left untreated, Aden ulcers can lead to corneal scarring, vision loss, and even loss of the eye in some cases.
Treatment of Aden ulcers usually involves a combination of systemic immunosuppressive medications, topical corticosteroids, and corneal protection. In some cases, surgical intervention such as corneal transplantation may be required to restore vision and prevent further damage.
Overall, Aden ulcer is a specific variant of Mooren's ulcer that affects the cornea and requires prompt medical intervention to prevent vision loss.
