Commonly known as Kala Motia, Glaucoma is an eye disease that mostly affects people in older age but congenital glaucoma is a possibility as well. Glaucoma is a condition in which damage to the optic nerve causes damage to the eyes. Optic nerve carries information about sight to the brain. In most cases, the damage to the optic nerve occurs when the pressure of matter increases in the front of the eye. But glaucoma related damage to the eye can occur even when the pressure of matter is normal.
- If your vision is 20/20, you will not develop glaucoma
- If there is no family history, you are safe
- Glaucoma develops if there is an increase in eye pressure
- If there are no symptoms, I do not need to get checked
- Glaucoma can only affect the elderly
Glaucoma usually develops in people over 40 years of age, but many a times congenital glaucoma also occurs in newborns. Its symptoms include redness in the eyes, watering of eyes, big eyes, corneal blurring etc.
If you are above 40 years of age and have a family history of Glaucoma then you should have your eye exam done in 1 or 2 years. If you have a health problem like history of diabetes or you are at risk of other eye diseases then you should a checkup from time to time too.
Scientists have developed the technique to build a retinal nerve cell with the help of stem cells in the lab which sends the visual signal from the eyes to the brain. This technique will be effective in treating blindness caused by glaucoma and multiple sclerosis. According to John Hopkins University researcher Donald Jake, ‘This will not only help to understand the structure of the optic nerve but also help in finding those medicines that are effective in treating these diseases. In this technique researchers used the Genome Editing Tool to change the stem cell and make them fluorescent with the help of proteins so that the affected cells can be distinguishable. Jack claims that the new cell will help in finding new cures for cataract and other related eye-related diseases.
World Glaucoma Week is from March 10 to 16 wherein awareness about this disease affecting the eyes is spread to eliminate the irreversible blindness caused by this disease.
Our Symptom Checker for children, men, and women, can be used to handily review a number of possible causes of symptoms that you, friends, or family members may be experiencing. There are many causes for any particular symptom, and the causes revealed in the symptom checker are not exhaustive. That is, they are not intended to be a listing of all possible causes for each symptom but are representative of some of the causes that can be underlying various symptoms.
A symptom is any subjective evidence of disease, while a sign is any objective evidence of disease. Therefore, a symptom is a phenomenon that is experienced by the individual affected by the disease, while a sign is a phenomenon that can be detected by someone other than the individual affected by the disease. For examples, anxiety, pain, and fatigue are all symptoms. In contrast, a bloody nose is a sign of injured blood vessels in the nose that can be detected by a doctor, a nurse, or another observer.
Health-care professionals use symptoms and signs as clues that can help determine the most likely diagnosis when illness is present. Symptoms and signs are also used to compose a listing of the possible diagnoses. This listing is referred to as the differential diagnosis. The differential diagnosis is the basis from which initial tests are ordered to narrow the possible diagnostic options and choose initial treatments.
Types & risk factors
There are three main types of ovarian tumors. The most common type, epithelial tumors, happens to the cells on the surface of the ovary, and it accounts for about 85 percent of malignant ovarian tumors, Cohn said. Less common are germ cell ovarian tumors, which occur in the egg-producing cells of the ovary, often in women younger than 30 years of age. The other type consists of sex cord-stromal ovarian tumors, which occur in the ovary cells that release female hormones.
The disease has several risk factors, including increased ovulation, Cohn told Live Science.
“Women who have ovulated more, which means they’ve never been pregnant and never breast fed, and haven’t taken birth control pills, have a higher chance of the disease compared to those who have been pregnant, breast fed and taken birth control pills,” he said.
Similarly, fertility medications that cause women to ovulate more frequently have been implicated as a risk factor for the disease, Cohn said.
