A drooping or sagging of the eyelid is medically known as ptosis or blepharoptosis. Drooping eyelids may occur on both sides (bilateral) or on one side only (unilateral), in which case it is more easily noticed.
- Congenital ptosis is eyelid drooping that is present at birth; when it develops later, it is referred to as acquired ptosis. Depending upon the severity of the condition, drooping eyelids may be barely noticeable or quite prominent.
- Some sagging of the skin and connective tissues occurs during the normal aging process, potentially leading to drooping of the eyelids.
- Other causes include conditions that affect the muscles and nerves of the eyelid as well as conditions that affect the skin and connective tissues of the eyelid.
- Rarely, tumors of the brain or eye area are the cause of drooping eyelids.
Other causes of ptosis
- Anatomical Variation
- Bacterial Infection
- Cobra Venom
- Eye or Orbital Tumor
- Horner Syndrome
- Myotonic Dystrophy
- Nerve Damage
- Surgical Procedures on the Eyes
- Third Cranial Nerve Palsy

Causes of Ptosis
Acute Flaccid Myelitis (AFM)
Acute flaccid myelitis (AFM) is a condition that affects the nervous system, causing weakening of the muscles and reflexes. Adenoviruses, poliovirus, non-polio enteroviruses, and West Nile virus can cause AFM. Symptoms and signs include drooping eyelids, difficulty swallowing and moving the eyes, facial weakness, and slurred speech. There is no treatment for acute flaccid myelitis.
Bell's Palsy (Facial Nerve Problems) Paralysis Causes and Treatments
Bell's palsy is one type of facial nerve paralysis. The 7th cranial nerve controls the muscles of the face, and although scientists do not know the exact cause of Bell's palsy, they think it may be due to nerve damage from an infection, for example, the flu, common cold viruses, and more serious infections like meningitis. The symptoms of Bell's palsy vary from person to person, but can include mild weakness to total paralysis, dry eye, dry mouth, eyelid drooping, drooling, mouth drooping, dry mouth, changes in taste, and excessive tearing in one eye. People with Bell's palsy usually don't need medical treatment, however, drugs like steroids, for example, prednisone seem to be effective in reducing swelling and inflammation are used when medical is necessary. Most people with Bell's palsy begin to recover within two weeks after the initial onset of symptoms. Full recovery may take three to six months.
Boils (Skin Abscesses)
A boil is a skin abscess, a collection of pus localized deep in the skin. There are several different types of boils. Among them are the following: furuncle or carbuncle, cystic acne, hidradenitis suppurativa, and pilonidal cyst.
Botulism is an illness caused by a neurotoxin produced by the bacterium Clostridium botulinum. There are three types of botulism: food-borne, wound, and infant. Symptoms include muscle paralysis, dry mouth, constipation, slurred speech, and blurred vision. If food-borne and wound botulism are detected early enough, they may be treated with an antitoxin. Infant botulism is treated intravenously with BabyBIG (Botulism Immune Globulin).
Brain Tumor (Symptoms, Signs, Types, Causes, Survival Rates)
A brain tumor can be either non-cancerous (benign) or cancerous (malignant), primary, or secondary. Common symptoms of a primary brain tumor are headaches, seizures, memory problems, personality changes, and nausea and vomiting. Causes and risk factors include age, gender, family history, and exposure to chemicals. Treatment is depends upon the tumor type, grade, and location.
Diabetes (Type 1 and Type 2)
Diabetes is a chronic condition characterized by high levels of sugar (glucose) in the blood. The two types of diabetes are referred to as type 1 (insulin dependent) and type 2 (non-insulin dependent). Symptoms of diabetes include increased urine output, thirst, hunger, and fatigue. Treatment of diabetes depends on the type.
Guillain-Barré Syndrome is an autoimmune disease of the nervous system due to damage to the myelin sheath around nerves. It is the most acquired nerve disease (neuropathy) and usually follows a virus infection but can also be associated with immunizations, surgery, and childbirth. The cause is unknown but appears to be related to autoimmune reaction. Symptoms include weakness beginning in the legs and progressing upward, lost reflexes, and in severe cases breathing can be affected. Patients can expect a slow but progressive recovery over several months maintaining vital functions and passively exercising the muscles. Plasmapheresis (removing toxic substances from the blood) has been shown to improve outcome and shorten the disease as well as intravenous immunoglobulin.
Migraine headache is a type of headache associated with a sensitivity to light, smells, or sounds, eye pain, severe pounding on one side of the head, and sometimes nausea and vomiting. The exact cause of migraine headaches is not known. Triggers for migraine headaches include certain foods, stress, hormonal changes, strong stimuli (loud noises), and oversleeping. Treatment guidelines for migraines include medicine, pain management, diet changes, avoiding foods that trigger migraines, staying hydrated, getting adequate sleep, and exercising regularly. Prevention of migraine triggers include getting regular exercise, drinking water daily, reducing stress, and avoiding trigger foods.
Multiple Sclerosis (MS) Symptoms, Causes, Treatment, Life Expectancy
Multiple sclerosis or MS is an autoimmune disorder in which brain and spinal cord nerve cells become demyelinated. This damage results in symptoms that may include numbness, weakness, vertigo, paralysis, and involuntary muscle contractions. Different forms of MS can follow variable courses from relatively benign to life-threatening. MS is treated with disease-modifying therapies. Some MS symptoms can be treated with medications.
Myasthenia gravis, a chronic autoimmune neuromuscular disease. Varying degrees of weakness of the voluntary muscles of the body are the main characteristics. A defect in the transmission of nerve impulses of the muscles is the cause of myasthenia gravis. Myasthenic crisis is when the muscles that control breathing weaken, which requires immediate medical attention. Symptoms include weakness of the eye muscles, facial expression, and difficulty swallowing. Treatment of myasthenia gravis includes medical therapies to control the symptoms of the disease.
A stroke is an interruption of the blood supply to part of the brain caused by either a blood clot (ischemic) or bleeding (hemorrhagic). Symptoms of a stroke may include: weakness, numbness, double vision or vision loss, confusion, vertigo, difficulty speaking or understanding speech. A physical exam, imaging tests, neurological exam, and blood tests may be used to diagnose a stroke. Treatment may include administration of clot-busting drugs, supportive care, and in some instances, neurosurgery. The risk of stroke can be reduced by controlling high blood pressure, high cholesterol, diabetes, and stopping smoking.
A sty is a bump that forms on the eyelid as a result of a blocked gland. Styes may be caused by infections, burns, or trauma to the eyelid. Most styes resolve on their own. The application of warm compresses can speed healing. In some cases, steroid injection or incision and drainage may be necessary. Keeping the area clean and consuming a diet high in omega-3-fatty acids may help prevent the formation of styes.
Thymoma is an uncommon cancer of the thymus gland. Many thymomas are asymptomatic. When symptoms do occur, they include chest pain, shortness of breath, and cough. Treatment of thymomas includes surgery, and sometimes, radiation and chemotherapy. The prognosis for thymoma is excellent when it is found in the early stages.
