H15: Disorders of sclera

Disorders of the sclera are a group of medical conditions affecting the sclera, which is the tough, white outer layer of the eyeball. These disorders can be caused by several factors including genetic abnormalities, inflammation, trauma, and certain systemic diseases. The most common symptoms are typically eye pain and redness, sensitivity to light, blurry vision, and sometimes, a noticeable thinning or blue coloration of the white part of the eye. These conditions may progress slowly or rapidly depending on their cause, leading to visual impairment or even blindness in severe cases. The ocular system, in particular the outer protective layer of the eye and sometimes the cornea, is the system most impacted by these disorders.
