Crocodile shagreen is an eye condition that affects the cornea, the clear, dome-shaped surface at the front of the eye. The name comes from its distinctive appearance: under a slit lamp examination, the cornea shows a grayish, polygonal pattern resembling the texture of crocodile skin. Although the pattern looks unusual, crocodile shagreen is usually a benign condition and does not significantly impact vision in most cases.
What Causes Crocodile Shagreen?
This condition is generally linked to age-related changes in the cornea. Over time, the arrangement of collagen fibers within the corneal stroma can become irregular, creating the characteristic mosaic pattern. Other causes may include:
- Degenerative changes due to aging
- Post-surgical alterations after certain eye procedures
- Corneal trauma or injury
- Rarely, it can be associated with inherited corneal disorders
Symptoms and Diagnosis
Most people with crocodile shagreen have no noticeable symptoms. The condition is often discovered incidentally during a routine eye exam. In some cases, patients may report:
- Mild glare or blurred vision
- Sensitivity to light
- Dryness or irritation
Diagnosis is made through a slit lamp examination, where the eye doctor observes the polygonal opacities in the cornea.
Is Treatment Necessary?
In the majority of cases, crocodile shagreen is harmless and does not require treatment. When symptoms such as dryness or irritation occur, lubricating eye drops may provide relief. If the condition is related to another corneal disorder, treatment will focus on the underlying cause.
When to See an Eye Specialist
Even though crocodile shagreen is usually benign, any changes in vision should not be ignored. Regular comprehensive eye exams are essential for early detection of corneal or retinal conditions.
