Signs and symptoms
Near vision will be blurred, and asthenopic symptoms like head ache and eye strain may occur while reading. Reduction of amplitude of accommodation by 2 dioptre or more is one of the important sign. Treatment
Underlying systemic or local causes should be treated. Weak convex lenses may be prescribed for near vision until accommodation improves to normal level. Accommodation exercises may be advised to improve accommodative power. == References ==
Sepsis affected about 49 million people in 2017, with 11 million deaths (1 in 5 deaths worldwide). In the developed world, approximately 0.2 to 3 people per 1000 are affected by sepsis yearly, resulting in about a million cases per year in the United States. Rates of disease have been increasing. Some data indicate that sepsis is more common among males than females, however, other data show a greater prevalence of the disease among women. Descriptions of sepsis date back to the time of Hippocrates. Signs and symptoms
In addition to symptoms related to the actual cause, people with sepsis may have a fever, low body temperature, rapid breathing, a fast heart rate, confusion, and edema. Early signs include a rapid heart rate, decreased urination, and high blood sugar. Signs of established sepsis include confusion, metabolic acidosis (which may be accompanied by a faster breathing rate that leads to respiratory alkalosis), low blood pressure due to decreased systemic vascular resistance, higher cardiac output, and disorders in blood-clotting that may lead to organ failure. Fever is the most common presenting symptom in sepsis, but fever may be absent in some people such as the elderly or those who are immunocompromised.The drop in blood pressure seen in sepsis can cause lightheadedness and is part of the criteria for septic shock.Oxidative stress is observed in septic shock, with circulating levels of copper and vitamin C being decreased. Cause
Infections leading to sepsis are usually bacterial but may be fungal, parasitic or viral.
