Acquired Sensory Loss
This is when somebody is born without any sensory loss, but then has an accident or illness which causes a sensory loss.
Diabetes: The most serious complication of diabetes for the eye is the development of diabetic retinopathy. Diabetes affects the tiny blood vessels of the eye and if they become blocked or leak then the retina and possibly your vision will be affected.
Measles: Measles blindness is the single leading cause of blindness among children in low income countries, accounting for an estimated 15,000 to 60,000 cases of blindness per year. There is a close synergism between measles and vitamin A deficiency that can result in xerophthalmia, with corneal ulceration, keratomalacia, and subsequent corneal scarring or phthisis bulbi.
Glaucoma: Glaucoma is an eye disease in which the optic nerve is damaged in a characteristic pattern. This can permanently damage vision in the affected eye(s) and lead to blindness if left untreated. It is normally associated with increased fluid pressure in the eye Perforated ear: If you have a perforated eardrum, your hearing may be affected. The extent of any hearing loss will depend on the size of the hole in your eardrum. A small puncture may only cause a slight loss of hearing, whereas a large puncture is likely to cause greater hearing loss. The hearing loss is only temporary and your hearing will return once your eardrum has healed. Swimmers ear: Otitis externa is often referred to as "swimmer's ear", as repeated exposure to water can make the ear canal more vulnerable to inflammation. Symptoms of otitis externa include: • Ear pain, which can range from moderate to severe
• A discharge of liquid or pus from the ear
• Some degree of temporary hearing loss
Usually only one ear is affected. With treatment, these symptoms should clear up within two-to-three days. In some cases the symptoms can persist for several months, which is known as chronic otitis externa.
There are genetic conditions like
Usher: people with Usher III experience a ''progressive'' loss of hearing and roughly half have vestibular dysfunction. The frequency of Usher syndrome type III is highest in the Finnish population, but it has been noted rarely in a few other ethnic groups.
Alstrom: This condition is very rare; about 500 affected people have been reported worldwide. Alström syndrome is a condition that affects many body systems. Many of the signs and symptoms of this condition begin in infancy or early childhood, although some appear later in life. Alström syndrome is characterized by a progressive loss of vision and hearing, Stickler: Children who have Stickler syndrome often experience eye disorders more commonly associated with older adults. • Severe nearsightedness. Children with Stickler syndrome are often born with severe nearsightedness, a vision disorder in which you can see near objects clearly, but objects farther away appear blurry. • Cataracts. Some children with Stickler syndrome are born with cataracts, a clouding of the focusing lens within the eye. Cataracts also may develop later in childhood. • Glaucoma. Glaucoma causes the pressure within the eye to increase, sometimes to the point that the optic nerve is damaged. • Retinal detachments. Problems with the lining of the eyeball, called the retina, are common with Stickler's syndrome. The retina is crucial to vision, so blindness can result if it pulls away or tears free from the back of the eyeball. The extent of hearing loss varies among people who have Stickler syndrome. It usually affects the ability to hear high frequencies and tends to worsen over time.
There are many accidents that can cause blindness and deafness, from car accidents to sporting or work accidents.
Old age can also be a cause of sensory loss.
