(1) During the last few years the optical fibers used in lachrymal duct endoscopy have been changed.

(2) From the lacrimal sacs, tears move down through the nasolacrimal duct and drain into the back of the nose.

(3) The area corresponding to the lacrimals , prefrontals and posterior nasals is difficult to recognise.

(4) Lacrimal cells

(5) Finally a naso-orbital lesion would emerge through a defect between the frontal and the lacrimal bones .

(6) The lacrimal bones are the smallest and most fragile of the cranial bones.

(7) A simple and easy-to-perform test assessing the function of the lacrimal glands is the Schirmer's test.

(8) The lacrimal bone is a small and fragile bone at the inner orbit of the eye through which the lacrimal duct runs.

(9) This will consequently elevate the lacrimal punctum into a more favourable position so that the tear film will drain into it more readily.

(10) Lacrimal cells

(11) The examination of 620 patients with affection of the salivary and lacrymal glands revealed sarcoidosis in 19 of them.

(12) The lacrimal bones are thin bones that form the anterior portion of the medial walls of the individual orbits.
