The Lacrimal apparatus starts from the lacrimal gland and ends at the Nasolacrimal ducts. The apparatus consists of the lacrimal gland and the lacrimal pathway. The integrity of the Lacrimal Apparatus in its secretory function and in its drainage mechanism is most vital for the normal functioning of the eye. Any factor which upsets the drainage mechanism distal to the sac or at the Nasolacrimal...
The lacrimal apparatus The lacrimal system consists of: 1Secretory portion: Comprises the following: aThe lacrimal gland: Which is divided into palpebral (Aqueoussecretion) (near the temporal aspect of upper eyelid) and orbital (near the eyeball) lobes, and it is situated in the upper temporal angle of the orbit. bAccessory lacrimal glands: glands of Krause and glands of wolfring. cMeibomian gl...
OBJECTIVE Myiasis is the invasion of human tissues by Diptera larvae. Ocular involvement is uncommon. Trauma is the major cause of lacrimal apparatus lesions. However, it is rarely associated with parasitic infestation. The objective of this paper is to report a case of canalicular laceration caused by Dermatobia hominis larva. DESCRIPTION An eight-year-old girl presented preseptal cellulitis...
Lacrimal sac tumors are rare with a clinical presentation that typically includes obstruction of the lacrimal drainage system and epiphora as the most frequent symptom. Cribriform adenoid cystic carcinoma (ACC) is the most common malignant epithelial tumor of the lacrimal gland and minor salivary glands; however, its occurrence in the lacrimal drainage apparatus is extremely rare. Given the rar...
Canaliculitis is an uncommon, often misdiagnosed diagnosis because canaliculitis can mimic many other common ocular conditions. Canaliculitis should be appropriately diagnosed and treated to avoid recurrent inflammation and possible obstruction of the upper portion of the lacrimal system. This review will serve as a concise resource to aid in diagnosis and provide updated management options.
Objective- Radiological and anatomical study of the Lacrimal apparatus system in one-humped camel of Iran (Camelus Dromedarius).Design- Prospective studyAnimals- Five heads (cut above the third cervical vertebra) of adult Dromedary camels' cadavers were collected from the slaughterhouse of the Najafabad area of Isfahan Province, Iran. Procedures- The anatomy of the nasolacrimal duct of one- hum...
The eye is a complex and highly developed organ which collects light from the surrounding environment, regulates its intensity through a diaphragm, focuses it through an adjustable lens to form an image on retina where this image is converted into a set of electrical signals transmitted to the brain. The eyes are protected in the skull by a bony box called the eye socket (orbit). The wall of th...
The normal and pathologic CT anatomy of the lacrimal drainage apparatus was examined during study of the orbits, nasal cavity, and paranasal sinuses in 100 patients with a variety of clinical complaints related to the inferomedial orbit. The bony lacrimal fossa, the nasolacrimal canal, and the fluid- or air-filled lacrimal sac and nasolacrimal duct were readily recognized in all cases. The lacr...
