Identification of hemopexin in tear film
Analytical Biochemistry, 2010Human tear fluid is a complex mixture of aqueous lipids, proteins, enzymes, and other biochemical and cellular elements. By conventional comparative proteomic approaches, we investigated the proteome in human tear fluid and compared the tear protein profile of normal control subjects with that of patients suffering from the ocular inflammatory disease ...

To survey briefly current knowledge on the normal preocular tear film.Sections deal with: (1) Formation of the film, its physical dimensions and rates of inflow and outflow of tears, and briefly the pathways of nervous control of tear production in the main lacrimal gland and accessory lacrimal tissue. (2) The protein and electrolyte composition of the

Interpretation of Tear Film Breakup
Archives of Ophthalmology, 1977Tear film breakup time (BUT) was measured in 25 normal subjects on 8 different occasions over a period of one month. Reproducibility of the BUT test and factors involved in interpretation of tear film breakup were studied. It was found that of 50 eyes, the average BUT ranged from five to 100 seconds, and that there were noticeable variations (P less ...

Video Biomicroscopy of the Tear Film
1998The tear film is produced by the lacrimal gland, the accessory lacrimal glands, and the goblet cells of the conjunctiva, with the meibomian glands of the eyelids providing an oily surface layer. The tear film covers the eye and is drained from the surface via two puncta that lead through the canaliculi to the lacrimal sac, which is in the lacrimal ...

Veterinary Clinics of North America: Small Animal Practice, 1990
Abnormalities of the lipid and mucin components of the preocular tear film may result from diseases of the eyelid margins and conjunctiva. Chronic keratoconjunctivitis with epithelial edema and superficial corneal neovascularization, with or without ulceration, characterizes qualitative tear diseases.

Tear Film Osmolarity in Epiphora
Ophthalmic Plastic & Reconstructive Surgery, 2012To examine whether patients complaining of epiphora have tears of a lower osmolarity.Sixty-three eyes of 39 patients attending an oculoplastic clinic with a primary complaint of epiphora, had their tear osmolarity recorded. Subjects were excluded if they had current or recent topical eye therapy, active ocular infection or allergy, ocular surface ...

Tear Osmolarity and Tear Film Parameters in Patients With Unilateral Pterygium
Cornea, 2014The aim of this study was to evaluate the differences in tear osmolarity and tear film parameters between pterygium-affected and healthy fellow eyes.The study enrolled 65 patients with unilateral pterygium. Tear osmolarity, tear film break-up time (TBUT), Schirmer I test measurements, fluorescein corneal staining, and conjunctival redness were ...

Duplex Tear Film Evaporation Analysis
Bulletin of Mathematical Biology, 2017Tear film thinning, hyperosmolarity, and breakup can cause irritation and damage to the human eye, and these form an area of active investigation for dry eye syndrome research. Recent research demonstrates that deficiencies in the lipid layer may cause locally increased evaporation, inducing conditions for breakup.

Formation and rupture of the tear film
Experimental Eye Research, 1973Abstract The formation of the preocular tear film successive to each blink is discussed in terms of surface chemical characteristics of the lid-cornea system. The interaction of conjunctival mucin with water and lipids is found to be the most important factor responsible for the spontaneous, rapid spreading of the fluid phases and for the stability ...

Diet, nutraceuticals and the tear film
Experimental Eye Research, 2013Nutrition disorders and their correlates such as obesity are increasingly prevalent worldwide. A number of studies to date have suggested numerous potential associations between diet and tear film health; this paper will provide a summary of the available literature.
