ICD-10: H27.139

The ICD-10-CM code H27.139 refers to the diagnosis of posterior dislocation of the lens in an unspecified eye. This condition is categorized under the broader group of disorders affecting the lens, specifically within the H27 classification, which encompasses various lens-related disorders.

Clinical Description

Definition

Posterior dislocation of the lens occurs when the lens of the eye is displaced from its normal position, specifically moving backward into the vitreous cavity. This can lead to significant visual impairment and may require surgical intervention depending on the severity and associated symptoms.

Etiology

The dislocation of the lens can result from several factors, including:
- Trauma: Blunt or penetrating injuries to the eye can cause the lens to dislocate.
- Congenital conditions: Some individuals may be born with predispositions to lens dislocation, such as Marfan syndrome or other connective tissue disorders.
- Complications from cataract surgery: Surgical procedures can sometimes lead to dislocation if the lens is not properly secured.

Symptoms

Patients with posterior dislocation of the lens may experience:
- Blurred or distorted vision
- Double vision (diplopia)
- Sudden changes in vision
- Possible signs of increased intraocular pressure

Diagnosis

Diagnosis typically involves a comprehensive eye examination, including:
- Slit-lamp examination: To visualize the lens and assess its position.
- Ophthalmoscopy: To examine the interior of the eye and check for any associated complications, such as retinal detachment.

Treatment

Management of posterior dislocation of the lens may include:
- Observation: In cases where vision is not significantly affected.
- Surgical intervention: Procedures such as lens extraction or repositioning may be necessary, especially if the dislocation leads to complications or significant visual impairment.
