ICD-10: H15.84

Scleral ectasia, classified under ICD-10 code H15.84, refers to a condition characterized by the abnormal thinning and bulging of the sclera, which is the white outer layer of the eyeball. This condition can lead to various visual disturbances and may be associated with other ocular or systemic disorders.

Clinical Description

Definition

Scleral ectasia is defined as a localized or generalized thinning of the sclera, resulting in an outward bulging of the eye wall. This condition can occur in one or both eyes and may be a consequence of various factors, including trauma, surgical interventions, or underlying connective tissue disorders.

Symptoms

Patients with scleral ectasia may experience a range of symptoms, including:
- Visual Disturbances: Blurred vision or distortion due to changes in the shape of the eye.
- Eye Discomfort: Patients may report a sensation of pressure or discomfort in the affected eye.
- Cosmetic Concerns: The bulging appearance of the eye can lead to psychological distress or social anxiety.

Etiology

Scleral ectasia can arise from several causes, including:
- Post-Surgical Changes: Following procedures such as cataract surgery or corneal transplantation, the sclera may become weakened.
- Trauma: Physical injury to the eye can compromise the integrity of the scleral tissue.
- Connective Tissue Disorders: Conditions like Ehlers-Danlos syndrome or Marfan syndrome can predispose individuals to scleral ectasia due to inherent weaknesses in connective tissues.

Diagnosis

Clinical Examination

Diagnosis typically involves a comprehensive eye examination, including:
- Slit-Lamp Examination: This allows for detailed visualization of the sclera and surrounding structures.
- Ocular Imaging: Techniques such as optical coherence tomography (OCT) or ultrasound biomicroscopy may be employed to assess the extent of scleral thinning and ectasia.

Differential Diagnosis

It is crucial to differentiate scleral ectasia from other conditions that may present similarly, such as:
- Scleral Perforation: A more severe condition where the sclera has ruptured.
- Pterygium: A growth of tissue on the conjunctiva that can affect the appearance of the eye.

Treatment

Management Strategies

The treatment of scleral ectasia depends on the severity of the condition and the symptoms presented. Options may include:
- Observation: In mild cases, regular monitoring may be sufficient.
