Degenerative Visual Loss

Degenerative sensory loss affects vision and hearing; this article focuses on degenerative visual loss. Approximately 2 million people in the UK are estimated to be registered for blindness or vision loss. (Action for the blind in 2011). The transition from the visual world to the blind world is full of difficulties and challenges for individuals living in today's society. There are many conditions that cause blindness; the most common existence; retinitis pigmentosa; age-related macular degeneration; diabetic retinopathy; glaucoma.

It is a disease in which loss of central nervous system function and loss of muscle coordination result in cell death. Degenerative diseases are delirium, Parkinson's disease, Alzheimer's disease and dementia. Most degenerative diseases have no cure. Causes of these neurodegenerative diseases include toxins, chemicals, genetics and viruses. Medicine-like treatments can improve pain relief and improve mobility. These diseases are mainly related to metabolic abnormalities and infectious diseases

Degenerative diseases are usually characterized by loss of nerve cells without signs of extensive inflammation or tissue necrosis and secondary gliosis (scar formation). It is now known that many diseases that were previously classified as degenerative diseases are associated with specific metabolic abnormalities or have other distinct causes (Table 24-1). Others are transmitted by infectious agents (see Chapter 25). However, many progressive diseases of unknown etiology are classified based on etiology and clinical findings. This also applies to diseases of many basal ganglia and other extrapyramidal systems. However, these diseases will be discussed in Chapter 26. Over time, certain biochemical and pathophysiological processes that support many of these diseases will be elucidated and their classification will change.
