Sclerocornea
Sclerocornea is a rare, congenital anomaly that affects the cornea of the eye. It is characterized by the partial or complete absence of the corneal limbus, leading to a non-transparent cornea that resembles the sclera, the white part of the eye.
Symptoms and Signs[edit | edit source]
Patients with sclerocornea often present with visual impairment or blindness. The condition may be associated with other ocular and systemic abnormalities, such as microphthalmia, aniridia, and Peter's anomaly.
Causes[edit | edit source]
The exact cause of sclerocornea is unknown, but it is thought to be due to a developmental defect during embryogenesis. It can occur sporadically or be inherited in an autosomal dominant or autosomal recessive manner.
Diagnosis[edit | edit source]
Diagnosis of sclerocornea is primarily based on clinical examination. Slit lamp examination may reveal a non-transparent cornea with no clear distinction between the cornea and the sclera. Additional tests, such as ultrasound biomicroscopy and optical coherence tomography, may be used to further assess the structure of the eye.
Treatment[edit | edit source]
There is currently no cure for sclerocornea. Treatment is aimed at managing the symptoms and preventing complications. This may include the use of contact lenses or corneal transplantation. However, the prognosis for visual recovery is generally poor.
