A cataract is a clouding of the lens in the eye which leads to a decrease in vision. Cataracts often develop slowly and can affect one or both eyes. Symptoms may include faded colors, blurry or double vision, halos around light, trouble with bright lights, and trouble seeing at night.
Astigmatism is a common vision condition that causes blurred vision. It occurs when the cornea (the clear front cover of the eye) is irregularly shaped or sometimes because of the curvature of the lens inside the eye.
#Hyperopia, or farsightedness, is a common vision problem, affecting about a fourth of the population. People with hyperopia can see distant objects very well, but have difficulty focusing on objects that are up close. The condition is sometimes referred to as ""hypermetropia"" rather than hyperopia. #hyperopia_farsightedness #farsightedness_symptoms
#Nearsightedness (myopia) is a common vision condition in which you can see objects near to you clearly, but objects farther away are blurry. It occurs when the shape of your eye causes light rays to bend (refract) incorrectly, focusing images in front of your retina instead of on your #retina. #myopia
#Uveitis is a form of eye inflammation. It affects the middle layer of tissue in the eye wall (uvea). Uveitis (u-vee-I-tis) warning signs often come on suddenly and get worse quickly. They include eye redness, pain and blurred vision. The condition can affect one or both #eyes. #uveitis_types_causes #uveitis_causes
They may look to you like black or #gray_specks, #strings, or #cobwebs that drift about when you move your #eyes and appear to dart away when you try to look at them directly. Most eye floaters are caused by age-related changes that occur as the jelly-like substance (#vitreous) inside your eyes becomes more #liquid.
#Blepharitis (blef-uh-RYE-tis) is inflammation of the eyelids. Blepharitis usually involves the part of the eyelid where the eyelashes grow and affects both eyelids. Blepharitis commonly occurs when tiny oil glands located near the base of the eyelashes become clogged
A #chalazion is a small, slow-growing lump or cyst that develops within the eyelid. They are not usually painful and rarely last longer than a few weeks. A chalazion can develop when a meibomian gland at the edge of an eyelid becomes blocked or inflamed. These glands produce oil that lubricates the surface of the #eye. #chalazion_causes
#Retinal detachment describes an emergency situation in which a thin layer of tissue (the retina) at the back of the #eye pulls away from its normal position. #retinal_detachment
Dry #eye syndrome (DES), also known as keratoconjunctivitis sicca (KCS), is the condition of having dry eyes. Other associated symptoms include irritation, redness, discharge, and easily fatigued eyes. Blurred vision may also occur. The symptoms can range from mild and occasional to severe and continuous. #Dry_eye syndrome #Dry_eye_syndrome
A #stye, also known as a #hordeolum, is a bacterial infection of an oil gland in the eyelid. This results in a red tender bump at the edge of the eyelid. The outside or the inside of the eyelid can be affected. The cause of a stye is usually a bacterial infection by Staphylococcus aureus. #bacterial #stye_causes
Batten disease is a fatal #disease of the nervous system that typically begins in childhood. Onset of symptoms is usually between 5 and 10 years of age. Often, it is autosomal recessive. It is the most common form of a group of disorders called the #neuronal ceroid lipofuscinoses (NCLs). #batten_disease
A #corneal #ulcer is an eye infection that causes an open sore on the cornea (the clear layer in front of the iris and pupil). Contact lenses, injuries, disorders, drugs, and #nutritional deficiencies can cause open sores (ulcers) to form on the cornea.
A dislocated #shoulder is when the head of the humerus is out of the shoulder joint. Symptoms include shoulder pain and instability. Complications may include a Bankart lesion, Hill-Sachs lesion, #rotator cuff tear, or injury to the axillary nerve. #shoulder_dislocation #rotator_cuff
Shoulder impingement syndrome is a syndrome involving #tendonitis of the rotator cuff muscles as they pass through the subacromial space, the passage beneath the acromion. It is particularly associated with tendonitis of the supraspinatus #muscle. #Shoulder_impingement
A cervical #rib in humans is an extra rib which arises from the seventh cervical vertebra. Their presence is a congenital abnormality located above the normal first rib. A #cervical rib is estimated to occur in 0.2% (1 in 500 people) to 0.5% of the population. #cervical_rib_thoracic #cervical_vertebra
#Torticollis, also known as wry neck, is a dystonic condition defined by an abnormal, asymmetrical head or neck position, which may be due to a variety of causes. The term torticollis is derived from the Latin words tortus for twisted and collum for #neck. #torticollis_causes #torticollis_symptoms
#Medication overuse #headache, occurring when #pain_medications are taken too frequently, can be caused by #acetaminophen (#Tylenol and others), #aspirin, #ibuprofen (#Advil and others), #OTC_analgesics with #caffeine (#Excedrin and others), as well as #narcotic_analgesics and other prescription pain medications
#Hypoglycemia, also called low blood sugar, occurs when the #sugar levels in your #blood are too low. #Hypoglycemia, that occurs in people with diabetes, however, it can also occur in people who don’t have #diabetes. #hypoglycemia_symptom
Type 2 #diabetes is a lifelong disease that keeps your body from using insulin the way it should. People with type 2 diabetes are said to have #insulin resistance. #Type2diabetes
#Gestational diabetes develops during pregnancy (gestation). Like other types of diabetes, gestational #diabetes affects how your cells use sugar (glucose). Gestational diabetes causes high #blood sugar that can affect your pregnancy and your baby's health. #Gestational_diabetes #health
#Diabetic #ketoacidosis is a serious complication of diabetes that occurs when your body produces high levels of #blood acids called ketones.The condition develops when your body can't produce enough #insulin. Insulin normally plays a key role in helping sugar (glucose) — a major source of energy for your muscles and other tissues — enter your cells. Without enough insulin, your body begins to break down fat as fuel.
#Hyperglycemia refers to high levels of #sugar, or #glucose, in the #blood. It occurs when the body does not produce or use enough insulin, which is a hormone that absorbs glucose into cells for use as energy. High blood sugar is a leading indicator of #diabetes. #hyperglycemia_causes
#Insulin is a peptide #hormone generated by beta cells of the #pancreatic_islets. #Insulin plays a key role in the regulation of blood glucose levels. Insulin also plays a significant role in the #metabolism. The digestive tract breaks down #carbohydrates into sugars and starches found in many foods—into glucose. Glucose is a form of sugar that infiltrates the bloodstream. As the assistant of insulin, cells throughout the body absorb glucose and utilize it for energy.
#Insulin_resistance is when cells in your #muscles, fat, and liver don’t respond well to #insulin and can’t easily take up glucose from your #blood. As a result, your pancreas makes more insulin to help glucose enter your cells. #Insulin_resistance
