ICD-10: Q12.4

Spherophakia, classified under ICD-10 code Q12.4, refers to a congenital condition characterized by the presence of abnormally shaped lenses in the eyes. This condition is a specific type of congenital lens malformation, where the lenses are spherical rather than the typical biconvex shape. Below is a detailed overview of spherophakia, including its clinical description, associated features, and implications for diagnosis and treatment.

Clinical Description of Spherophakia

Definition and Characteristics

Spherophakia is defined as a congenital anomaly of the lens, where the lens is smaller and more spherical than normal. This abnormal shape can lead to various visual impairments, including refractive errors such as myopia (nearsightedness) or hyperopia (farsightedness) due to the altered curvature of the lens. The condition may also be associated with other ocular anomalies, including cataracts and glaucoma, which can further complicate the clinical picture.

Etiology

The exact cause of spherophakia is not fully understood, but it is believed to be a result of genetic factors and developmental disturbances during embryogenesis. It can occur as an isolated condition or as part of a syndrome, such as Marfan syndrome or other connective tissue disorders, which may also present with ocular manifestations.

Clinical Features

Patients with spherophakia may exhibit the following clinical features:
- Spherical Lens Shape: The primary characteristic is the abnormal spherical shape of the lens.
- Refractive Errors: Patients often experience significant refractive errors, necessitating corrective lenses.
- Associated Anomalies: There may be an increased risk of other ocular conditions, including cataracts, which can develop at an early age, and secondary glaucoma due to lens dislocation or other factors.
- Visual Impairment: Depending on the severity of the lens malformation and associated conditions, patients may experience varying degrees of visual impairment.

Diagnosis

Clinical Examination

Diagnosis of spherophakia typically involves a comprehensive eye examination, including:
- Visual Acuity Testing: To assess the degree of visual impairment.
- Slit-Lamp Examination: To evaluate the lens shape and any associated cataracts or other ocular anomalies.
