What is Keratitis?
keratitis is an inflammation of the cornea, which is the transparent outermost layer of the eye that covers the pupil and iris. It is the most common type of eye inflammation (the colored ring around the pupil). Keratitis is most commonly caused by an infection or an injury to the cornea.
The following are the causes of Keratitis bacterial, viral, parasitic, and fungal infections. Infectious keratitis can occur as a result of corneal damage. However, an injury might inflame the cornea without causing a subsequent infection.
Viral keratitis is quite frequent, and the viruses that cause it include the following:
Adenovirus, one of the viruses that cause upper respiratory infections.
This is the same virus that causes cold sores, and it can lead to shingles.
Varicella-zoster (commonly known as shingles) is a herpes virus that causes chickenpox and shingles.
Bacterial keratitis is a less common cause of keratitis than viral keratitis. In developed countries, parasitic and fungal keratitis are uncommon.
Infectious keratitis typically begins on the cornea's outer layer, but it can progress deeper into the cornea, increasing the risk of vision impairment.
Keratitis that is not infectious is a symptom of several autoimmune disorders, including rheumatoid arthritis and Sjogren's syndrome.
Keratitis can arise as a result of trauma to the front of the eye, such as with improperly fitting contact lenses, corneal surgery (including LASIK surgery), or any other lesion to the cornea.
Contact lens wearers are at an elevated risk of developing infectious keratitis. If a person suspects that he or she is getting an eye infection, lens usage should be discontinued immediately.
Symptoms
Among the symptoms of keratitis are the following:
The appearance of a red eyeA sensation of something in the eye, such as sandSusceptibility to lightEyes that are wetVision blurredOpening the eyelids is difficult.
When keratitis is caused by an injury or infection, such as the herpes simplex virus, it usually affects just one eye; however, when keratitis is caused by another cause, both eyes may be affected.
Diagnosis
Your health care provider will inquire about your symptoms, vision, and general health. Your doctor or an eye expert will examine the surface of the cornea using a magnifying device to check for a microscopic ulcer produced by a viral infection. When caused by herpes simplex, this ulcer sends out star-like branches and is most seen after a dye is used to briefly tint the cornea. Infection of the cornea with Herpes simplex may be followed by infection of the eyelid. On the eyelid, small, painful blisters resembling lip cold sores may form.
Additionally, your physician may:
Evaluate your visual acuity and clarity (visual acuity)
Assesses your pupil's sensitivity to light.
Examine your eye with a slit lamp, a specialized device.
Gently swab inside the eyelid to obtain a sample for culturing in the laboratory.

Lewy body dementia, alternatively referred to as Dementia with Lewy bodies, is the second most common type of progressive dementia, behind Alzheimer's disease. Lewy bodies are protein deposits that accumulate in nerve cells in parts of the brain that are critical for thought, memory, and movement (motor control).
Lewy body dementia is characterized by a progressive deterioration of mental functions. Visual hallucinations and disturbances in alertness and attention may occur in people with Lewy body dementia. Other complications include indications and symptoms of Parkinson's disease such as tight muscles, slow movement, difficulty walking, and tremors.
Symptoms
Among the indications and symptoms of Lewy body dementia are the following:
Visual hallucinations Hallucinations
Seeing things that aren't there — is frequently one of the initial symptoms of schizophrenia, and they frequently reoccur. Individuals suffering from Lewy body dementia may experience hallucinations of forms, animals, or humans. Hallucinations of sound (auditory), smell (olfactory), or touch (tactile) are all possible.
Parkinson's disease symptoms (parkinsonian signs) can include delayed movement, tight muscles, tremors, or a shuffling gait. This can result in a fall.
Inadequate control of bodily functioning (autonomic nervous system). The nervous system regulates blood pressure, pulse, perspiration, and the digestive process. This component of the nervous system is frequently damaged by Lewy body dementia. This can result in abrupt reductions in blood pressure when standing (orthostatic hypotension), dizziness, falls, loss of bladder control (urinary incontinence), and bowel problems such as constipation.
Cognitive difficulties.
You may experience similar cognitive (thinking) impairments to those associated with Alzheimer's disease, such as confusion, poor focus, visual-spatial difficulties, and memory loss.
Sleep disturbances.
You could be suffering from rapid eye movement (REM) sleep behavior disorder, which causes you to physically act out your dreams while sleeping. This could include punching, kicking, yelling, or screaming while sleeping.
Tis the Season for Christmas Macarons
The greatest time of year to make macarons for gifts and party favors is during the holidays. You can only imagine how grateful your loved ones will be for the time and work you put into making such adorable gifts for them in their honor. When you receive these gorgeous French pastries, the "WOW" factor is unmatched. Even more so when you take the time to pipe them into cute characters or fill them with boozy macaron flavors that can't be purchased in supermarkets. I hope that you would find these macaron designs appealing and worthy of imitating.
Recommendations for Immunizations for Aging Adults
Immunizations are commonly thought of as something we all receive as children – but less so as we mature. Certain childhood immunizations, on the other hand, wear off over time, leaving adults and the elderly unprotected.
All adults, regardless of their health status, are encouraged to receive recommended vaccines to help prevent the spread of dangerous diseases. However, it is critical for older persons with chronic health conditions to protect themselves from further illnesses by staying current on their vaccinations. What immunizations are recommended for persons 65 years and older?
Vaccine Against Seasonal Flu (Influenza)
Influenza can be a serious illness for the elderly, requiring hospitalization and, when combined with other illnesses, proving fatal. Since 2010, the CDC estimates that up to 710,000 flu-related hospitalizations have occurred. Flu season can begin as early as October and run until May - it is therefore critical to receive the flu vaccination as soon as possible for maximum coverage. Vaccinations against influenza can protect against up to four different viruses, including H1N1, H3N2, and two distinct influenza B viruses. This vaccination is most frequently given as a shot.
TD Vaccine or Tdap Vaccine
This immunization protects against Diphtheria, Tetanus, and Whooping Cough and is provided for the first time at the age of two months. It is advised again for preteens aged 11-12 and then every ten years thereafter. For certain patients, Medicare Part D insurance will cover up to 100% of immunization costs.
