H00-H06: Disorders of eyelid, lacrimal system and orbit

Disorders of the eyelid, lacrimal system, and orbit encompass a wide variety of conditions impacting the upper part of the face around the eye. Eyelid disorders could include issues like drooping lids (ptosis), inflamed edges (blepharitis), or chalazions, which are lumps in the eyelid. Lacrimal system disorders often involve problems with the tear ducts, like blockages, which can make eyes teary or cause infections. Orbit disorders typically refer to issues affecting the eye socket, such as inflammation, tumors, or even fractures. These disorders can result from various causes, like infections, allergies, injuries, or even certain systemic diseases. The common signs and symptoms most often include redness, pain, swelling, teary eyes or dry eyes, vision problems, or a visible lump or deformity. The progression and impact of these disorders would largely depend on the specific condition and its severity.
