Oculoplasty, or oculoplastic surgery, involves medical and surgical treatment for deformities and abnormalities of the eyelids, lacrimal (tear) system, orbit (bony cavity around the eye), and the adjacent face. This specialized branch of ophthalmology requires adherence to strict medical guidelines and legal frameworks to ensure patient safety ...
A dacryoadenectomy is the surgical removal of a lacrimal gland. [8] A dacryocystectomy is the surgical removal of a part of the lacrimal sac. [8] A dacryocystorhinostomy (DCR) or dacryocystorhinotomy is a procedure to restore the flow of tears into the nose from the lacrimal sac when the nasolacrimal duct does not function. [8] [11]
Canthoplasty refers to a plastic surgery of the medial and/or lateral canthus. This technique is common in cosmetic procedures, as well as procedures that address eyelid function or malposition. [3] A canthotomy involves cutting the canthus, often performed to release excessive orbital pressure (i.e., from orbital hemorrhage or infection). [4]
It attaches to the frontal process of the maxilla, the lacrimal groove, and the tarsus of each eyelid. It has a superficial (anterior) and a deep (posterior) layer, with many surrounding attachments. It connects the medial canthus of each eyelid to the medial part of the orbit. It is a useful point of fixation during eyelid reconstructive surgery.
Lacrimal nerve – conveys sensation to the skin areas of the lateral orbital (eye socket) region, except for the lacrimal gland. Frontal nerve – conveys sensation to the skin areas of the forehead and the scalp. Supraorbital nerve – conveys sensation to the skin areas of the eyelids, the forehead, and the scalp.
The lacrimal gland is a compound tubuloacinar gland, it is made up of many lobules separated by connective tissue, each lobule contains many acini.The acini composed of large serous cells which, produce a watery serous secretion, serous cells are filled with lightly stained secretory granules and surrounded by well-developed myoepithelial cells and a sparse, vascular stroma.
As with all oil glands, lacrimal caruncles can become clogged, causing a pimple, whitehead, or pustule beneath the skin. Clogged oil and sweat glands in the caruncle can affect tear ducts. Treatment for dry eyes due to clogged glands includes refraining from rubbing the eyes and rinsing the eyes with clear water frequently during the day ...
Involutional stenosis is probably the most common cause of nasolacrimal duct obstruction in older people. It affects women twice as frequently as men. Although the inciting event in this process is unknown, clinicopathologic study suggests that compression of the lumen of the nasolacrimal duct is caused by inflammatory infiltrates and edema.
