The ocular surface in keratoconjunctivitis sicca

Tear film osmolarity and ocular surface disease in two rabbit models for keratoconjunctivitis sicca.

We report the natural history of keratoconjunctivitis sicca (KCS) in two rabbit models. The first one (full KCS model) was created by closing the lacrimal gland excretory duct, and removing the nictitating membrane and harderian gland. We created the second one (lacrimal gland duct only [LGDO]-KCS model) by closing the lacrimal gland excretory duct. Although tear film osmolarity was abnormally ...

Disruption of TGF-β Signaling Improves Ocular Surface Epithelial Disease in Experimental Autoimmune Keratoconjunctivitis Sicca

BACKGROUND TGF-β is a pleiotropic cytokine that can have pro- or anti-inflammatory effects depending on the context. Elevated levels of bioactive TGF-β1 in tears and elevated TGF-β1mRNA transcripts in conjunctiva and minor salivary glands of human Sjögren's Syndrome patients has also been reported. The purpose of this study was to evaluate the response to desiccating stress (DS), an experimenta...

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 ...
