Schirmer's test of lacrimation.

Schirmer's test is a simple, semiquantitative test of tear production. It is based on the physical tendency of a fluid to travel along a strip of porous material by capillary action due to surface tension. Sterile strips, standardized and prepackaged, are available from local scientific supply houses. The low cost and simplicity of this test make it useful in confirming the diagnosis of diseases involving decreased lacrimal secretion.

Dry eye syndrome and other tear film abnormalities.

The goal of cosmetic blepharoplasty is to obtain an improvement in the appearance of the eyelids without causing functional or symptomatic alterations in the patients. Patients with undiagnosed problems in tear production who have cosmetic blepharoplasties are a common source of extremely dissatisfied patients with alarming ocular symptoms. Although keratoconjunctivitis sicca is the most common manifestation of an abnormal tear film state, there are other conditions of which the eyelid surgeon should be aware. Knowledge of methods used in the diagnosis of states of tear deficiency will allow the surgeon to better select candidates for cosmetic eyelid procedures.

Epidermoid carcinoma of the lacrimal sac: a clinicopathological case report.

Epidermoid carcinomas of the lacrimal sac are rare. We report a case that illustrates the difficulties in their diagnosis. When the diagnosis was made in our patient the tumour had extended beyond the sac wall and treatment was unsuccessful. The prognosis of these tumours depends on early diagnosis and complete excision, which demands a high degree of suspicion in all cases of chronic tearing, chronic dacryocystitis or a nonreducible mass in the area of the lacrimal sac. Consultation with an otolaryngologist is esential in both diagnosis and management.

Canaliculitis: review of 12 cases.

Canaliculitis must be considered in patients with chronic unilateral conjunctivitis. Pouting of the punctum, canalicular swelling and expression of particulate matter or stones are important clinical signs, and dacryocystography often helps in diagnosis. Meticulous microbiologic studies may not reveal actinomycetes. Canaliculotomy with silver nitrate cauterization is effective treatment.

Mucosal cyst of lacrimal gland fossa simulating lacrimal gland neoplasm.

A 28-year-old man presented with an orbital tumour that was localized by computérized tomography to the fossa of the right lacrimal gland. A benign mixed tumour of the lacrimal gland was the clinical diagnosis, but lateral orbitotomy revealed a subperiosteal cystic mass in the lacrimal gland fossa that extended superiorly and medially into the frontal sinus. Light microscopic examination showed a cyst lined by nonkeratinized stratified squamous epithelium with occasional goblet cells; blood products were present in the lumen, and a chronic inflammatory cell infiltrate was noted in the subepithelial tissue. The possible origins of this mucosal tissue are discussed.

Lids, lacrimals, and lashes.

The eyelids and lashes serve to protect the globe from foreign bodies and injuries, and the lacrimal system protects the eyes through lubrication of the corneal and conjunctival surfaces. This article discusses trauma, infection, inflammation, anatomic abnormalities, and tumors that may result in serious complications interfering with normal eye function.
