Cornea plana 2
Cornea plana 2 (pronounced: /kɔːrˈniːə ˈpleɪnə tuː/) is a rare genetic disorder characterized by a flattened corneal curvature, leading to decreased vision. The term "Cornea plana 2" is derived from the Latin words "cornea" meaning "horny", referring to the clear, dome-shaped surface covering the front of the eye, and "plana" meaning "flat". The number "2" indicates that it is a variant of the condition.
Symptoms
The primary symptom of Cornea plana 2 is a flattened cornea, which can lead to decreased vision. Other symptoms may include hypermetropia (farsightedness), and keratoconus (a condition in which the cornea thins and bulges out into a cone shape).
Causes
Cornea plana 2 is caused by mutations in the KERA gene. This gene provides instructions for making a protein that is found in the cornea. Mutations in the KERA gene disrupt the structure of the cornea, leading to its flattened shape.
Diagnosis
Diagnosis of Cornea plana 2 is based on a clinical examination of the eye. Genetic testing can confirm a diagnosis by identifying a mutation in the KERA gene.
Treatment
Treatment for Cornea plana 2 is focused on managing the symptoms. This may include corrective lenses to improve vision. In severe cases, a corneal transplant may be necessary.
