H30-H36: Disorders of choroid and retina

H31: Other disorders of choroid

"Other disorders of the choroid" is a broad classification that refers to a variety of conditions affecting the choroid, a layer of blood vessels and connective tissue between the sclera, or white of the eye, and the retina, which is sensitive to light. These disorders can occur due to diseases, injuries, or congenital defects. Some of the conditions included in this category lead to changes in the choroid's structure or function, resulting in inflammation, abnormal growth of blood vessels, or thinning, among other changes. Symptoms vary widely depending on the exact condition but may include vision problems such as blurry vision or dark, floating spots in the visual field. Moreover, the progression of these disorders can be slow or rapid and potentially affect the health of the retina, leading to more serious vision issues.
