Canine lacrimal and third eyelid superficial glands’ macroscopic and morphometric characteristics

Abstract

Aspectos macroscópicos e morfométricos das glândulas lacrimal e superficial da terceira pálpebra de cães (Canis familiares; LINNAEUS, 1758)

Histological, histochemical and fine structure studies of the lacrimal gland and superficial gland of the third eyelid and their significance on the proper function of the eyeball in alpaca (Vicugna pacos)

“…The LG plays an important role in the protection of the cornea and the conjunctiva from drying up and also nourishes and lubricates the eye, contributes in metabolite exchange, protects the cornea surface from injuries caused by foreign bodies, and has bactericidal and bacteriostatic properties [3,4,30,48,49]. According to Dartt [7], the tear film consists of water, electrolytes and proteins.…”

Avaliação de 67 casos de protrusão da glândula da terceira pálpebra em cães (2005-2010)

“…No conhecimento dos autores, este é o primeiro trabalho a relatar maior predisposição de fêmeas, pois não há descrição quanto à predileção por gênero. Entretanto, há referência de que as fêmeas são mais susceptíveis ao desenvolvimento da ceratoconjuntivite seca (Sanchez et al, 2007) e que possuem a glândula da terceira pálpebra menos espessa (Cabral et al, 2005). A literatura não estabelece se a condição é mais evidente de forma uni ou bilateral e quanto a um olho ser mais afetado que outro (Slatter, 2005;Hendrix, 2007); no entanto, neste estudo observou-se que, na condição unilateral, houve maior acometimento do olho direito em relação ao esquerdo.…”

Qualitative and quantitative tear film abnormalities in dogs

“…The lacrimal system consists of a secretory and an excretory component which are responsible for the production and excretion of the tear film, respectively (CABRAL et al, 2005). The secretory portion comprises the orbital lacrimal and third eyelid glands, in addition to conjunctival goblet cells (CABRAL et al, 2005).…”

“…The secretory portion comprises the orbital lacrimal and third eyelid glands, in addition to conjunctival goblet cells (CABRAL et al, 2005). The lacrimal glands are histologically characterized as tubuloacinar structures consisting of secretory units, ducts and supporting connective tissue.…”

“…Connective tissue, blood vessels and nerve fibers comprise the glandular stroma. Male lacrimal glands are larger than female ones (CABRAL et al, 2005). The orbital lacrimal and third eyelid glands are innervated by sympathetic and parasympathetic nerve fibers and primary control is mainly exerted by the parasympathetic nervous system (GRAHN & STOREY, 2004).…”
