Effect of Artificial Tears on Tear Stress Test
Optometry and Vision Science, 2008To determine the effect of two artificial tears of different viscosities in the relief of environmental dry eye induced with a novel tear stress test (TST).A novel TST was developed and validated. The following four test conditions were evaluated in 12 healthy normal subjects in a cross-over and subject masked study; unprotected (no test solution used),

Artificial Eyes and Tear Measurements
Ophthalmology, 1980Ninety-four consecutive persons with unilateral enucleations or eviscerations were tested by the Schirmer I and Schirmer II tests for tear production. The findings on the artificial eye were compared with those on the companion, living (control) eye. The collected data were subjected to statistical analysis.

Whatʼs Artificial in Artificial Tears?
Optometry and Vision Science, 1986After reviewing tear film physiology, and tear film disorders, the author discusses the ingredients found in artificial tear solutions. Choosing the best artificial tear solution for each patient is often confusing because many solutions are available.

Colloid Osmotic Pressure of Artificial Tears
Journal of Ocular Pharmacology and Therapeutics, 1985While the total osmolality of the aqueous tears and tear substitutes has received much attention in the past few years, the colloidal osmolality or the oncotic pressure (which includes the Donnan effect), has received practically no attention except for one single foreign publication.

The designing of artificial tear products has been undergoing constant reevaluation for many decades. Currently available artificial tear formulations differ remarkably with regard to their compositions. Today, significant controversies exist among pharmaceutical scientists in this field.

Soluble Artificial Tear Inserts
Archives of Ophthalmology, 1977This article reports a new concept in the treatment of tear film abnormalities. Solubilization of an artifical tear insert provides a continuous flow of polymer into the tear film in place of intermittent drop therapy. The physiochemical properties of succinylated collagen were studied in vitro and compared favorably with presently available tear ...

Classification of Artificial Tears
1998Natural tears serve three main functions: they maintain the metabolism of the ocular surface tissues, afford a smooth surface that allows regular light refraction, and lubricate the ocular surface to facilitate blinking. They also have other functions, such as specific and non-specific antimicrobial and buffer effects, etc. Natural tears have a complex

Toxic preservatives in artificial tears
Ugeskrift for LægerDry eye disease (DED) is a common condition, especially among the elderly. Artificial tears are formulated to relieve the symptoms of DED. However, selecting the most suitable option can be challenging, as the products differ in various aspects, including eligibility for reimbursement, pricing, packaging formats, composition, and presence of ...

Effect of preservatives in artificial tear solutions on tear film evaporation *
Ophthalmic and Physiological Optics, 1991It has been suggested that certain preservatives in artificial tears may affect the stability of the tear film lipid layer. In the present study, tear film evaporation rate (TER) was measured with a modified Servomed Evoporimeter to determine whether preservatives affected tear stability. Two solution combinations were compared in a cross‐over study of

A Unique Therapeutic Artificial Tear Formulation
1994The tear film has a unique electrolyte balance distinct from aqueous humor and serum.1. We postulated that this electrolyte balance was critical for the maintenance of ocular surface health.
