Sensory impairments is common in old age


It has been observed that older folks are normally suffer from sensory impairment for example vision and hearing problems. Sensory impairments upsurge as people enter in old age period and many older people experience a sensory damage in their life.



Medical specialists have elaborated in their studies that changes in sensitivity to contrast, color, and glare, stereoacuity, and peripheral vision can affect visual function of elderly people. Reports indicated that severe impairment occurs in older people due to several medical conditions that include age-related macular degeneration, cataracts, glaucoma, and diabetic retinopathy.


Macular degeneration occur due to the breakdown of cells in the macula of the retina that causes yellow deposits, known as drusen, to form under the retina. The wet form of the condition, in which abnormal blood vessels surrounding the drusen leak, causes subretinal haemorrhage and scarring.

Diabetic retinopathy develops due to increased vessel permeability. Blood and lipid leakage leads to macular edema and hard exudates (composed of lipids). In progressive disease, new fragile blood vessels form that hemorrhage easily.

Cataract is another common sensory impairment in old age which occurs due to a clouding of the normally clear ocular lens that’s usually caused by a clumping of proteins in the nucleus of the lens. Consequently, less light can reach the retina.

Glaucoma in older people is a severe form of sensory damage in which there is a vision loss because of increased intraocular pressure. In open-angle glaucoma the anterior chamber angle is normal, but anomalies of the trabecular meshwork or the Schlemm canal, as well as in the rate of aqueous fluid production lead to the rise in pressure. In closed-angle glaucoma, the anterior chamber angle itself is clogged, often by an iris that is thickened or displaced anteriorly by an enlarged lens.

In final analysis, it is interpreted that aging people have extra burden of sensory deficits. It is a critical component of health and immensely impact on the life of any individual.
