Angularis nigra

Angularis nigra is a medical term referring to a darkened area or line seen at the inner corner of the eye, specifically at the junction of the sclera and cornea. This condition is often benign and can be seen in individuals of all ages. However, it is more commonly observed in older adults due to age-related changes in the eye.

Causes

The exact cause of Angularis nigra is not well understood. It is believed to be due to the deposition of lipofuscin, a type of pigment that accumulates in the eye with age. Other factors such as chronic inflammation, exposure to sunlight, and certain medications may also contribute to its development.

Symptoms

Angularis nigra is typically asymptomatic, meaning it does not cause any symptoms. It is often discovered during a routine eye examination. In some cases, individuals may notice a dark line or spot at the inner corner of their eye.

Diagnosis

The diagnosis of Angularis nigra is usually made based on a physical examination of the eye. The doctor may use a slit lamp to examine the front part of the eye in detail. In some cases, additional tests such as an eye ultrasound or biopsy may be needed to rule out other conditions.

Treatment

As Angularis nigra is usually benign and does not cause any symptoms, treatment is often not necessary. However, if the condition is causing cosmetic concerns, treatment options such as laser therapy or surgical removal may be considered. It is important to discuss these options with a healthcare provider to understand the potential risks and benefits.
