Introduction

Introduction The human sclera is composed of collagen tissue, and the iron in the body is an important cofactor for synthetic collagen. If the body is deficient in iron, collagen synthesis is insufficient, the sclera becomes thin, and it is impossible to effectively cover the brown-black choroid in the eyeball. When it is seen under natural light, it is light blue. Studies have shown that Asian children's eye sclera should be grayish white, if it is blue, it can be considered from anemia. Because, children with pelvic blood should have pale skin mucosa, often appear later than the blue light of the sclera.

Cause

This must start from the human physiology. Because the human sclera is composed of collagen tissue, and the iron in the body is an important cofactor for synthetic collagen. If the body is deficient in iron, collagen synthesis is insufficient, the sclera becomes thin, and it is impossible to effectively cover the brown-black choroid in the eyeball. When it is seen under natural light, it is light blue.

Surface scleritis, whether simple or nodular, is a benign recurrent mild disease with self-limiting, with a course of 1 to 2 weeks or more, without treatment.

Diffuse and nodular scleritis, the vascular plexus of the affected part is open, but the course of the disease is lingering, in addition to local administration, corticosteroid preparations should be added.

Necrotizing scleritis is a serious condition with most of the vascular plexus atresia.
