Other disorders of sclera
The sclera is the tough, fibrous outer layer of the eye that covers the white part of the eye. It is an important structure that provides protection and support to the eye. While most people are familiar with common scleral disorders like scleritis and episcleritis, there are other disorders of the sclera that can affect the health of the eye.
- Scleral thinning: Scleral thinning is a condition where the sclera becomes thinner than normal, making it weaker and more susceptible to damage. This condition can be caused by trauma, infection, or inflammation. Scleral thinning can lead to a condition called scleral ectasia, where the sclera bulges outwards. This can cause visual distortion and discomfort.
- Scleral staphyloma: Scleral staphyloma is a condition where the sclera bulges outwards due to a weakness in the scleral tissue. It can be caused by trauma, infection, or inflammation. Scleral staphyloma can cause visual distortion and discomfort, and in severe cases, it can lead to vision loss.
- Scleral calcification: Scleral calcification is a condition where calcium deposits form in the sclera. It is most commonly seen in elderly people and can be a sign of underlying medical conditions such as renal failure or hyperparathyroidism. Scleral calcification can cause visual distortion and discomfort.
- Scleral melting: Scleral melting is a rare condition where the sclera starts to dissolve. It is most commonly seen in people with autoimmune disorders and can be caused by inflammation or infection. Scleral melting can cause visual distortion and discomfort, and in severe cases, it can lead to vision loss.
It is important to seek medical attention if you experience any symptoms related to scleral disorders. Your doctor may recommend treatments such as anti-inflammatory medications, antibiotics, or surgery depending on the underlying cause and severity of the condition. Early diagnosis and treatment can help prevent complications and preserve vision.
In conclusion, while scleritis and episcleritis are commonly known scleral disorders, there are other disorders of the sclera that can affect the health of the eye. Scleral thinning, scleral staphyloma, scleral calcification, and scleral melting are some of the other conditions that can cause visual distortion and discomfort, and in severe cases, vision loss. Seeking medical attention and early diagnosis and treatment are important to prevent complications and preserve vision.
