Disorders of the Eye & Ear

The complexity of the eye structure and function includes muscles, blood vessels and nerves that constantly adjust to allow light to enter and image transmission to reach the brain for interpretation. The ear consists of three dimensions--the outer ear that catches the sound, the middle ear that changes sound waves into vibrations and the inner ear creates nerve signals that go to the brain for interpretation. Both organs are susceptible to disorders that can affect the ability to see and hear clearly.

Acoustic Neuroma

An acoustic neuroma, a slow-growing, noncancerous tumor, affects the nerve located behind the ear that connects the brain and the ear. According to National Institutes of Health website MedlinePlus, the cause links to an uncommon genetic disorder known as neurofibromatosis type 2. In most cases, symptoms of an acoustic neuroma appear after the age of 30 and include vertigo, hearing loss and ringing in the ear. Headache, facial numbness, facial pain and loss of balance may also be experienced. Diagnostic testing for acoustic neuroma involves CT scan, hearing test or an magnetic resonance imaging, or MRI. Treatment options include surgery to remove the tumor and reduce the pressure on surrounding nerves, radiation therapy to slow tumor growth or monitoring the growth of the tumor until symptoms require intervention.

Barotitis Media

Barotitis media, better known as ear popping, is a dysfunction of the Eustachian tube. The work of the Eustachian tube is to balance the air pressure on the inside of the ear with the outside pressure, such as during altitude changes or scuba diving. Upper respiratory congestion often causes blockage of the Eustachian tube, which can result in barotitis media. Symptoms include dizziness and ear pain. Treatment includes opening the Eustachian tube to relieve the pressure. Chewing gum and yawning are often successful in equalizing the pressure. In cases that do not respond to conservative treatment, a doctor should be consulted. Complications from unresolved barotitis media include a ruptured eardrum, hearing loss and an acute ear infection.

Corneal Infections

The cornea is the five-layered covering that protects the eye from germs and dust, reports the National Eye Institute. Damage to the cornea, such as a scratch or a foreign object, gives an opening for bacteria or fungi to enter the cornea and develop a corneal infection. Susceptible people for corneal infections include contact lens wearers, those with dry eyes and immunosuppressed people. Symptoms include eye pain, redness, burning and discharge. Corneal infections can easily develop into a corneal ulcer. Treatment depends on the cause, and includes an antibiotic, antifungal or antiviral eye drop. A corticosteroid eye drop is likely for inflammation. If there is severe damage to the cornea, a corneal transplant may be the best option.

Blepharitis

Blepharitis is an inflammation of the eyelids that presents with symptoms such as an itchy, irritated red eye. Bacteria residing in the eyelashes can produce scales that irritate the eye. Medication treatment for blepharitis includes antibiotics and steroid applications. Treatment for blepharitis includes a strict cleaning regimen to remove the crusts that form and following the medication treatment as prescribed.
