CHANGES OF VISUAL ORGAN IN PATHOLOGY OF THE EAR, NOSE AND THROAT

Chronic disorders of the nose and throat are often the reason of blepharitis, conjunctivitis, dacryocystitis.

Inflammatory diseases of paranasal sinuses can result in devel­opment of severe ophthalmic complications, such as uveitis, retini­tis, optic neuritis, panophthalmitis. In severe cases it is possible the translocation of infection into the orbit with development of phleg­mon, abscess or thrombophlebitis, which are dangerous for patient's life. The main symptoms of such injuries are exophthalmos, oph­thalmoplegia, hemosis of conjunctiva, oedematous phenomena from the side of the optic nerve.

In tumours of paranasal sinuses it can be observed the exoph­thalmos of uninflammatory origin with translocation of the eye to the corresponding side, stagnant optic papilla and atrophy of the optic nerve.

Purulent processes in the ears give the same complications as inflammation of paranasal sinuses. There are observed also reflec­tory blepharospasm, when disorder of labyrinthus — pendular nys­tagmus. Under formation of otogenic cerebral abscess there are observed disfunction of pupillar responses, mydriasis, paralysis of oculomotor and abducent nerves, an oedematous optic disc, hemi-anopsy.

CHANGES OF VISUAL ORGAN IN OTHER GENERAL DISEASES

Diseases of the dental-jaw system cause periostites, orbital ab­scess, keratites, uveites, retinites, optic neurites.

In diseases of biliary tracts and intestines there are observed chronic blepharitis, hordeolum, chalazion.

Pneumoniae can be a reason of metastatic uveitis.

Thus, knowledge of early and following ophthalmological symp­toms of general diseases stipulate timely diagnosis of the basic path­ological process, evaluating its course severity, choosing an effec­tive treatment, determination of clinical recovering and prognosis, and also prophylaxis and early revealing of eye's diseases, patho­genetic approach for their treatment.
