Abstract
Squamous blepharitis is the more common of the two main types of blepharitis. It is frequently associated with dandruff or seborrheic dermatitis and presents with small white scales at the roots of the eyelashes. The patient often has chronically irritable eyes. The blockage of the duct of a tarsal gland may cause a cyst due to the retained secretion. The skin around the eyelids becomes edematous, inflamed, and scaly. There is intense itching. This is due to allergy to cosmetics or a variety of ophthalmic medication, especially sulphonamides. Herpes zoster ophthalmicus affects the skin supplied by the ophthalmic division of the fifth cranial nerve. Ptosis can be unilateral or bilateral, complete or partial, and congenital or acquired. In bilateral ptosis, the patient's head is characteristically tilted backwards to see through the narrowed palpebral fissure. Trichiasis can cause a unilateral red eye from the chronic irritation of the cornea or conjunctiva. Xanthelasma is a fatty deposit in the skin, usually bilateral and occur-ring at the medial part of the upper lid. Basal cell carcinoma usually appears on the lower lid margin as a raised nodule with a characteristic pearly rolled edge. The blockage of the lacrimal drainage system may occur either in the punctum, the canaliculus, or the naso-lacrimal duct, resulting in tearing.
