Conjunctivitis often occurs in children, less often in older people, and even less often in people of working age. Usually the agent of conjunctivitis gets into the eye from the hands.
Dacryoliths (lacrimal stones) can occur in any part of the tear system, more often in men. Although the pathogenesis of dacryolithiasis is not entirely clear, it is suggested that secondary stasis of tears in inflammatory obstruction can accelerate the formation of dacriliths and squamous metaplasia of the lacrimal sac epithelium.
Obstruction of the nasolacrimal canal - this condition is better called a delayed restoration of patency of the nasolacrimal canal, t. It is often resolved spontaneously.
The constriction (stenosis) of the lower lacrimal point is one of the frequent causes of persistent lacrimation. About narrowing of a lacrimal point it is possible to speak at its diameter less than 0.1 mm.
Dacryocystitis is an infectious inflammation of the lacrimal sac, which arises from the obstruction of the nasolacrimal canal, which is usually caused by staphylococci. There are acute and chronic course of dacryocystitis.
Inflammation of the tubule (canaliculitis) often occurs secondary against the background of inflammatory processes of the eyes, conjunctiva. The skin in the tubule area becomes inflamed. There is marked lachrymation, mucopurulent discharge from lacrimal points.
Diseases of the lacrimal gland (dacryoadenitis) are rare, often on the one hand. It arises as a complication of common infections - influenza, acute respiratory infections, tonsillitis, mumps, scarlet fever, diphtheria, etc.
In the normal state of organs, tear production corresponds to shedding. If the mechanism of lacrimation is disturbed, or if excessive tearing is observed during normal shedding, then in both cases a tear will roll over the edge of the lower eyelid - the so-called lachrymation.
