Allergic Conjunctivitis; an Inflammation of the Eye that Causes Itchy, Red, Gritty Eyes

Allergic Conjunctivitis


Allergic Conjunctivitis is an eye inflammation (conjunctiva) caused by an allergic reaction to substances like pollen or mold spores. Oral antihistamines, such as loratadine, fexofenadine, and cetirizine, are commonly used to treat Allergic Conjunctivitis. These drugs are usually taken once a day. Antihistamine eye drops include Zaditor and Alaway. Theses eye drops help relieve the symptoms of conjunctivitis, while the oral dose help treat a runny nose and other symptoms. Like all types of pink eye, allergic conjunctivitis is common but not usually serious. Allergic conjunctivitis usually affects both eyes.

Common eye drops can help reduce inflammation and symptoms. The eye can develop serious inflammation with damage to the optic nerve if a flare-up continues for more than a couple weeks. Allergic Conjunctivitis usually occurs when a person's eyes are exposed to an allergen, a substance that causes the body's immune system to overreact. People with all forms of allergic conjunctivitis develop intense itching and burning in both eyes. It can be caused by infection by bacteria or viruses, allergy, and physical or chemical irritation. It is rarely vision-threatening but can significantly decrease the quality of life for patients.

With the use of High-Frequency alternating current, Radiofrequency Ablation Device convert Electromagnetic Energy into Heat Energy

Image
Radiofrequency Ablation Device RFA is a minimally invasive technique that may be done in a doctor's office or a hospital. The majority of patients are able to return home the same day. RFA can be done with or without minimal sedation. If anaesthesia is utilised, the patient is generally kept awake and alert enough to explain what they are feeling during the nerve stimulation and lesioning. The following are the steps involved in an RFA: ·         On a procedure table, the patient is lying on his or her stomach. An intravenous (IV) line is established if sedation is utilised so that relaxation medication (sedation) can be administered. ·         To reduce the danger of infection, the skin above the treatment region (neck, mid-back, or low back) is thoroughly washed. ·         A numbing drug (anaesthetic) is injected into the location of the RFA injection site to numb a small patch of skin. Radiofrequency ablation is a process that is reasonably safe and low-risk. Some pati

The Isocyanates Market to Witness Robust Growth in North America and Asia Pacific

Image
  Organic compounds that contain an isocyanate group are referred to as isocyanates. They are a family of highly reactive, low molecular weight chemicals. Isocyanates are extensively used in the automobile, electronics, and construction industry. Moreover, they are used in a variety of industries using chemicals such as certain coatings/linings, adhesives, lacquers, two pack spray paints, and in foam production such as fillers or insulation. Isocyanates are also used in the production of rigid foams, coatings, elastomers, and adhesives. Increasing demand form the construction industry due to its highly reactive chemical property is expected to be a key factor driving the Isocyanates market growth. Among regions, the Isocyanates M arket is witnessing robust growth in North America and Asia Pacific due to the rapid growth of various end-use industries such as automotive, electronics, and construction, with India, China, and the U.S. being the major growth engines.

Air Purifier works as a Sanitizer in the air which helps in reducing pollutants, allergens, and toxins

Image
  Air purifier   Within a confined area, an air purifier eliminates organic and inorganic impurities from the air. The clean air is sent out into the living space after these devices catch pollutants and particles in the air. Dust mites, mould spores, chemicals, poisons, and scents are all trapped by these filters. These gadgets are frequently touted as appropriate tools for asthmatic patients and others who suffer from airborne allergen allergies. An indoor Air purifier ensures the filtering of the air inside a closed room, which it catches and releases as clean air. If the windows may be opened, it functions in addition to the necessary natural ventilation. A contrast must be noted between a professional model and a residential device, since neither provides the same level of air treatment or overall performance. Pollens, fine particles PM2.5 and PM10, VOCs (Volatile Organic Compounds), viruses, and germs are all effectively removed by a professional air purifier with a HEPA 13 or
