ICD-10: H30.042

Focal chorioretinal inflammation, specifically coded as ICD-10 code H30.042, refers to localized inflammatory processes affecting the choroid and retina in the macular or paramacular regions of the left eye. This condition can significantly impact vision due to its proximity to the macula, which is responsible for central vision.

Clinical Description

Definition

Focal chorioretinal inflammation is characterized by the presence of inflammatory lesions in the choroid and retina. The inflammation can be due to various etiologies, including infectious agents, autoimmune responses, or other inflammatory conditions. The term "focal" indicates that the inflammation is localized rather than diffuse, which can help in diagnosing and managing the condition effectively.

Symptoms

Patients with focal chorioretinal inflammation may experience a range of symptoms, including:
- Blurred vision: Particularly in the central visual field due to the involvement of the macula.
- Scotomas: Areas of visual loss or blind spots in the visual field.
- Photopsia: Perception of flashes of light, which may occur due to irritation of the retina.
- Visual distortion: Straight lines may appear wavy or bent (metamorphopsia).

Causes

The inflammation can arise from several underlying causes, including:
- Infectious agents: Such as viruses (e.g., cytomegalovirus), bacteria, or fungi.
- Autoimmune diseases: Conditions like sarcoidosis or Behçet's disease can lead to chorioretinal inflammation.
- Toxoplasmosis: A parasitic infection that can cause focal lesions in the retina.

Diagnosis

Diagnosis typically involves a comprehensive eye examination, including:
- Fundoscopy: To visualize the retina and choroid for signs of inflammation.
- Fluorescein angiography: This imaging technique helps assess blood flow in the retina and identify areas of leakage or inflammation.
- Optical coherence tomography (OCT): Provides cross-sectional images of the retina, allowing for detailed assessment of the macular structure.

Treatment

Management of focal chorioretinal inflammation may include:
- Corticosteroids: To reduce inflammation, either systemically or via intravitreal injections.
- Antibiotics or antivirals: If an infectious cause is identified.
- Immunosuppressive therapy: For autoimmune-related inflammation.
