Keratoconjunctivitis sicca (dry eye)

Neurturin-deficient mice develop dry eye and keratoconjunctivitis sicca.

PURPOSE Neurturin has been identified as a neurotrophic factor for parasympathetic neurons. Neurturin-deficient (NRTN(-/-)) mice have defective parasympathetic innervation of their lacrimal glands. This study was conducted to evaluate tear function and ocular surface phenotype in NRTN(-/-) mice. METHODS Determined by tail genomic DNA PCR, 25 NRTN(-/-) mice and 17 neurturin-normal (NRTN(+/+)) ...

Dry Eye in Vernal Keratoconjunctivitis

The purpose of this comparative cross-sectional study was to investigate the use of standardized clinical tests for dry eye in pediatric patients with active and quiet vernal keratoconjunctivitis (VKC) and to compare them with healthy children. We recruited 35 active VKC, 35 inactive VKC, and 70 age-matched control healthy subjects. Each child underwent a complete eye examination, including vis...

Keratoconjunctivitis sicca due to sarcoidosis.

SARCOIDOSIS is well recognized as a cause of swelling of the lacrimal glands and enters into the differential diagnosis of tumours of this region (DukeElder, 1952). Such swellings may be followed, in some cases, by a form of keratoconjunctivitis sicca (Ainslie and James, 1956; Gruber, 1956). The association of systemic sarcoidosis with keratoconjunctivitis sicca in the absence of swelling of th...

Iatrogenic keratoconjunctivitis sicca in a dog

Qualitative and quantitative abnormalities in primary components of the tear can alter the dynamics of the lacrimal film, compromising its function. Lipids, an aqueous fraction and mucoproteins constitute the lacrimal film. Keratoconjunctivitis sicca (KCS) is a disease commonly diagnosed in dogs. It is characterized by the deficiency of the aqueous fraction in the lacrimal film that results in ...
