Scleral hardness

The sclera refers to the white part of the periphery of the eyeball. It is the fibrous membrane of the outermost layer of the eye. It is also a soft tissue. The sclera is called white eye, accounting for 5/6 of the eye fiber membrane, about 30% of the total area. The edema and invasive changes occur in the scleral tissue around the limbus, and a dense angiogenesis phenomenon is formed. The corneal margin is immersed in the deep tissue of the cornea, causing corneal opacity, which often occurs in the corneal margin. Basic Information Specialist Category: Ophthalmic Examination Category: Other Inspections Applicable gender: whether men and women apply fasting: not fasting Tips: Before the examination, it is contraindicated: it should be taken to the hospital for examination. Normal value Common features of scleritis are conscious pain, photophobia and tearing. Inflammation has a deep red nodular bulge, which is normal except for this. Clinical significance Abnormal results edema and invasive changes around the scleral tissue of the limbus, and formed a dense angiogenesis phenomenon, which is immersed in the deep corneal tissue by the limbus, causing corneal opacity, which often occurs in the corneal margin. However, it can also occur in the central or parenchymal layer of the cornea, but not in the lesion of the sclera. The corneal opacity begins to appear grayish or grayish yellow, then becomes white, typically tongue or triangle, with the tip toward the center of the cornea. It is also common in the corneal stroma layer to retain linear turbidity, the appearance of which is ceramic-like, and this turbidity will never disappear once it appears.
