Conjunctivitis most often occurs in children, less often in the elderly, and even less often in people of working age. Usually, the pathogen of conjunctivitis gets into the eye from the hands.
Dacryoliths (tear stones) can occur in any part of the lacrimal system, more often in men. Although the pathogenesis of dacryolithiasis is not entirely clear, it is suggested that secondary stagnation of tears during inflammatory obstruction may accelerate the formation of dacryoliths and squamous metaplasia of the lacrimal sac epithelium.
Obstruction of the nasolacrimal duct - this condition is better called delayed restoration of patency of the nasolacrimal duct, since it often resolves spontaneously.
Narrowing (stenosis) of the lower lacrimal point is one of the common causes of persistent lacrimation. Narrowing of the lacrimal point can be considered when its diameter is less than 0.1 mm.
Dacryocystitis is an infectious inflammation of the lacrimal sac that occurs due to obstruction of the nasolacrimal canal, usually caused by staphylococci. There are acute and chronic forms of dacryocystitis.
Inflammation of the canaliculus (canaliculitis) often occurs secondarily against the background of inflammatory processes of the eyes and conjunctiva. The skin in the area of the canaliculus becomes inflamed. There is marked lacrimation, mucopurulent discharge from the lacrimal points.
Diseases of the lacrimal gland (dacryoadenitis) are rare, usually on one side. It occurs as a complication of common infections - flu, acute respiratory infections, tonsillitis, mumps, scarlet fever, diphtheria, etc.
In a normal state of the organs, tear production corresponds to tear drainage. If the tear drainage mechanism is disrupted or excessive tear secretion is observed during normal tear drainage, then in both cases, tears will roll over the edge of the lower eyelid - the so-called lacrimation.
