ICD-10: H21.312

ICD-10 code H21.312 refers to "Exudative cysts of iris or anterior chamber, left eye." This classification falls under the broader category of disorders affecting the iris and anterior chamber of the eye. Below is a detailed clinical description and relevant information regarding this condition.

Clinical Description

Definition

Exudative cysts of the iris or anterior chamber are fluid-filled sacs that develop in the eye's anterior segment, specifically affecting the iris or the space between the cornea and the lens (anterior chamber). These cysts can arise due to various underlying conditions, including inflammation, trauma, or other ocular diseases.

Etiology

The formation of exudative cysts can be attributed to several factors:
- Inflammation: Conditions such as uveitis can lead to the accumulation of fluid and the formation of cysts.
- Trauma: Injury to the eye may result in the development of cysts as part of the healing process.
- Tumors: Certain benign or malignant tumors can cause cystic changes in the iris or anterior chamber.
- Congenital Factors: Some individuals may be born with predispositions to develop such cysts.

Symptoms

Patients with exudative cysts may experience a range of symptoms, including:
- Visual Disturbances: Depending on the size and location of the cyst, vision may be affected.
- Irritation or Discomfort: Patients may report a sensation of pressure or discomfort in the affected eye.
- Changes in Eye Appearance: The presence of cysts can alter the appearance of the iris or lead to visible swelling in the anterior chamber.

Diagnosis

Diagnosis typically involves:
- Ophthalmic Examination: A comprehensive eye exam, including slit-lamp examination, is crucial for identifying the presence of cysts.
- Imaging Studies: In some cases, ultrasound or optical coherence tomography (OCT) may be used to assess the cyst's characteristics and impact on surrounding structures.

Treatment

Management of exudative cysts depends on the underlying cause and severity of symptoms:
- Observation: If the cysts are asymptomatic and not affecting vision, a watchful waiting approach may be adopted.
- Medical Therapy: Anti-inflammatory medications or corticosteroids may be prescribed to reduce inflammation and prevent further cyst formation.
- Surgical Intervention: In cases where cysts cause significant visual impairment or discomfort, surgical removal may be necessary.
