Abstract:
AbstractIntroduction:We performed endoscopic dacryocystorhinostomy in cases diagnosed with both anatomical and functional lacrimal obstruction, and here report results for the latter cases.Methods:Sixty-eight endoscopic dacryocystorhinostomies were performed for functional obstruction on 44 patients. The indication for surgery was epiphora in 66 patients and recurrent dacryocystitis in two. The minimum follow up was six months.Results:There was complete cure in 44 (65 per cent) patients, partial cure in nine (13 per cent) and no improvement in 15 (22 per cent). Revision surgery was performed in five of the 15 cases with no improvement, after which there was an overall complete cure in 47 patients (69 per cent), partial cure in 10 (15 per cent) and no improvement in 11 (16 per cent).Discussion:Endoscopic dacryocystorhinostomy is indicated in cases of epiphora with a diagnosis of functional lacrimal obstruction. Currently available investigations cannot reliably distinguish partial anatomical obstruction from pump failure.

O mecanismo de drenagem lacrimal do cão não é totalmente conhecido. O objetivo deste estudo foi avaliar a via lacrimal excretora do cão normal do ponto de vista histológico, na tentativa de melhor conhecer esta estrutura. Método: realizou-se um estudo envolvendo 30 cães normais (60 olhos), sem raça definida, adultos, pesando de 4,15 a 30 kg. Esses animais foram submetidos a exame ectoscópico (exame externo), dacriocistográfico e avaliação histológica da via lacrimal excretora. Resultados: a via lacrimal excretora do cão é formada por pontos, canalículos e saco lacrimal, e ducto nasolacrimal, o qual se abre no meato inferior da narina, observados ao exame dacriocistográfico. Histologicamente, a via lacrimal excretora do cão é, em parte, revestida por epitélio escamoso estratificado não queratinizado, o qual repousa em estroma de tecido conjuntivo denso; e, em parte, revestida por epitélio estratificado colunar, repousando em estroma de tecido conjuntivo frouxo. As regiões do saco lacrimal e do ducto nasolacrimal são circundadas por rica rede vascular. Não foram evidenciadas fibras musculares circundando (intimamente dispostas) a via lacrimal excretora do cão, ou justapostas a essa via. Conclusão: o cão não possui estruturas contráteis envolvendo intimamente a via lacrimal excretora, podendo-se supor que o mecanismo de drenagem lacrimal não envolva mecanismos de contração muscular.
The mechanism of lacrimal drainage system in dogs is not still completely understood. The aim of this study was to evaluate the histological aspects of lacrimal drainage system in the healthy dog, trying to know better this anatomical structure. Method: thirty healthy adult cross-bred dogs (sixty eyes), weighting from 4.1 to 30 kg were used in this study. These animals were submited to an extern ophthalmic examination, dacryocystorhinography and a histological analysis of lacrimal drainage route. Results: the lacrimal drainage system is composed by points, lacrimal canaliculi, lacrimal sac and nasolacrimal duct. As showed at the dacryocystorhinography, the nasolacrimal duct opens towards to the meato inferior da narina. By the histological analysis, the lacrimal drainage route is partially composed by non-keratinized stratified squamous epithelium which lies on dense conjunctive tissue stroma, and partially covered by stratified columnar epithelium over a layer of cells of loose conjunctive tissue stroma. The lacrimal sac and nasolacrimal duct areas are rounded by a well developed blood vessels net. It were not observed muscle fibers rounding, or nearby, the lacrimal drainage route. Conclusion: contractile structures rounding lacrimal drainage route were not observed in the dog. We supposed that the mecanism of lacrimal drainage is not related to a muscle contractile responses.

Abstract:
The lacrimal system is made up of both the lacrimal secretory system and the nasolacrimal drainage system. The secretory system consists of the glands that make up the tear film (the lacrimal gland, the accessory glands of Krause and Wolfring, and the meibomian glands). The nasolacrimal drainage system consists of the puncta, canaliculi, lacrimal sac, and nasolacrimal duct. These two systems provide for the production and maintenance of the precorneal tear film as well as the drainage of tears from the eye. The normal functioning of these two systems is essential for proper optical refraction, preservation of corneal integrity, and ocular comfort. The physiology of tear production and distribution requires normal eyelid anatomy and mobility. Blinking spreads the tears vertically over the ocular surface. It also adds two important components to the tear film: lipid from the meibomian glands and mucin from the conjunctival goblet cells. The horizontal flow of tears to the medial canthus is along the tear meniscus at the eyelid margin. This requires normal contour and eyelid apposition to the globe and an adequately functioning orbicularis pump mechanism. Both of these functions can be compromised by horizontal and vertical eyelid laxity or by eyelid margin deformities. The lacrimal gland begins in embryologic development as epithelial buds arising from the conjunctiva of the superior temporal fornix. Canalization of the epithelial buds to form ducts begins in utero, but full development of the gland does not occur until three to four years postnatal. The lacrimal gland provides the principal aqueous secretory component of the tear film. It is located just behind the superolateral orbital rim within a depression in the lateral aspect of the orbital roof (the lacrimal gland fossa). The gland’s convex/concave shape reflects its location between the roof of the orbit and the globe. The gland is divided into a larger orbital lobe and a smaller palpebral lobe by the lateral horn of the levator aponeurosis. The orbital lobe lies behind the orbital septum and immediately above the lateral horn of levator.

Abstract:
The common complaint of a watering eye may be caused by a variety of problems, including lacrimal hyposecretion, lacrimal hypersecretion, or blockage of the lacrimal drainage system. This system is a complex membranous channel whose function depends on the interaction of anatomy and physiology. Effective tear drainage depends on a variety of factors, including the volume of tear secretion, eyelid position, and anatomy of the lacrimal drainage passages. Epiphora is defined as an abnormal overflow of tears down the cheek. The patient with symptomatic tearing may have a normal lacrimal drainage system overwhelmed by primary or secondary (reflex) hypersecretion or a drainage system that is anatomically compromised and unable to handle normal tear production. On the other hand, a patient with partial drainage obstruction may have a concomitant reduction in tear production and therefore be completely asymptomatic or may even suffer from symptomatic dry eye syndrome. Epiphora is determined by the balance between tear production and tear drainage, not by the absolute function or dysfunction of either one. The causes of lacrimal drainage problems can be divided into two categories: anatomic and functional. Anatomic obstruction refers to a mechanical or structural abnormality of the drainage system. The obstruction may be complete, such as punctal occlusion, canalicular blockage, or nasolacrimal duct fibrosis, or partial, caused by punctal stenosis, canalicular stenosis, or mechanical obstruction within the lacrimal sac (i.e., dacryolith or tumor). In patients with functional obstruction, epiphora results not from anatomic blockage but from a failure of lacrimal drainage physiology. This failure may be caused by anatomic deformity such as punctal eversion or other eyelid malpositions, but can also result from lacrimal pump inadequacy caused by weak orbicularis muscle action. It is helpful to determine whether the patient’s complaint is true epiphora or a “watery eye.” Detailed history-taking and careful examination will help direct the evaluation of a tearing eye. A host of clinical tests have been described, and the selection of appropriate tests will depend on the initial history and ophthalmic examination. 13-1-1 History-Taking. Any clinical evaluation should begin with a thorough history. A complaint of watery eye does not necessarily imply a lacrimal drainage problem.

Abstract:
Reconstruction of the medial and lateral canthal region can be quite challenging because in these two regions, soft tissue (canthal tendons) interacts directly with bony tissue to determine the location and function of the eyelids. Poor knowledge of the anatomy in these regions or poor surgical technique and planning can lead to poorly functioning eyelids in both opening and closing as well as associated lacrimal drainage and pump deficiency and aesthetic asymmetry. Tissue loss in these regions can be from many causes, including trauma, inflammation, and neoplasia. When dealing with malignant neoplasia, it is particularly important to ensure that surgical margins are free of tumor prior to reconstruction. Particularly in the medial canthus, incompletely excised lesions can spread deep into the orbit, into the periocular sinuses (ethmoid and maxillary), and down the nasolacrimal system. Therefore, excision with margin control (Mohs, frozen, or permanent sections) is warranted. When a tumor is heading toward the orbit, this author recommends margin control with permanent fixed tissue to ensure proper diagnosis. When tumor cannot be cleared with this technique an exenteration is offered. Repair of the canthal regions involves first repairing deep structures and any bony defects with autologous or synthetic materials, followed by resuspending eyelid structures to a location analogous to their native location. If remnants of the canthal tendon are present, it can be sutured to periosteum, or sutured or wired to bone through drilled pilot holes. Other techniques may involve using titanium miniplates to fixate the soft tissue to bone. If canthal tendon is not present, periosteum of the orbital rim can be fashioned into a flap simulating a canthal tendon, or the tarsus of the eyelid can be split with one arm forming a new canthal tendon. No matter what technique is used, care must be taken to ensure the tendon or tendon substitute is fixed into the orbit, deeper than the orbital rim; failure to do so will cause the eyelids to function poorly. Once deeper structures are restored, repair of the soft tissue must be undertaken.
