H02: Other disorders of eyelid

The group of conditions under the category "Other disorders of eyelid" consists of various disorders that affect the eyelids, which are the folds of skin that cover and protect our eyes. These conditions might arise due to different causes such as injuries, infections, allergies, dysfunctions in the oil glands of the eyelid, or aging. Generally, these disorders are transmitted via direct or indirect contact for certain infectious diseases while others may be due to genetic predisposition. Common symptoms across this group of disorders include, but are not limited to, eyelid swelling, redness, pain, itching, increased tear production, a lump on the eyelid, and in severe cases, visual disturbances. The progression of these disorders could range from slow, causing gradually worsening discomfort, to quick, causing immediate distress. The affected system is primarily the integumentary system, which includes the skin, hair, nails, and accessory glands. However, it could also indirectly affect the ocular system by potentially disrupting normal vision.
