Summary of common ophthalmology diseases

Glaucoma】 What is glaucoma? Glaucoma is a disease that causes damage to the optic nerve. The optic nerve is made up of many nerve fibers, and when intraocular pressure increases, it can lead to nerve fiber damage and cause visual field defects. Early mild visual field defects are often difficult to detect, but if the optic nerve is severely damaged, it can lead to blindness. Early detection, diagnosis and treatment of glaucoma is the key to preventing optic nerve damage and blindness. How can glaucoma be detected early? Regular eye exams are the best way to detect glaucoma. Your doctor will perform the following tests: 1) measurement of intraocular pressure; 2) atrial angle examination; 3) fundoscopy; and 4) binocular visual field examination. Some tests may have to be repeated several times. Of course, you do not have to do every test. Is it curable? Generally speaking, glaucoma cannot be cured, but it can be managed. Once diagnosed, frequent care, observation and treatment are needed to control the eye pressure in order to protect the optic nerve and prevent vision damage. Eye drops, oral medications, laser surgery and microsurgery have been quite successful in controlling eye pressure over the long term. Many people believe that glaucoma is cured when medications or surgery bring high eye pressure under control to a safe level. In fact, glaucoma is only controlled; it is not yet cured. Even after medication or surgery has successfully controlled eye pressure, routine checkups with an ophthalmologist are necessary. Dry eye】 What is dry eye? Dry eye is a type of disease in which the tear film is unstable and the eye surface is damaged due to abnormalities in the quantity or quality of tears, resulting in eye discomfort. Causes of dry eye Many causes may cause dry eye, including: 1. age; 2. high temperature environment; 3. wind, dust, smoke and dry weather; 4. allergens such as chytrid fever; 5. certain medications; 6. eyelid disease, eye trauma, rheumatic arteritis, etc.; [Conjunctivitis] What is conjunctivitis Conjunctivitis is a clear film covering the inner surface of the eyelid, the surface of the white of the eye at the front of the eye, and the conjunctiva is the inflammation or infection that occurs in the The most important thing to remember is that the conjunctiva is a very inflammatory or infected membrane, and when the conjunctiva is stimulated in any way, it becomes edematous and red, so conjunctivitis is also called “pink eye” and can involve one or both eyes. Prevention points: 1, used to wash hands with warm water and soap; 2, do not share eye water or eye ointment with others; 3, when the eyes are red and swollen, should not wear corneal contact lenses, should not eye makeup, once found eye infection, seek help from a doctor. Use paper towels or disposable towels. Common childhood eye diseases: Common childhood eye diseases include nystagmus, visual impairment, eye inflammation, eye trauma, etc. Once you notice signs of vision loss in your child, you should go to the hospital immediately. Nystagmus is a condition in which both eyes are unable to focus on the target at the same time. If one of the eyes is squinted, diplopia occurs. Some children with strabismus can develop monopia, but no longer use the strabismic eye, and then amblyopia develops. Sometimes one eye trembles constantly, or when fatigued, ill, or looking at near-side objects. Infants often have tremors in both eyes, but if they are still present at 2-3 months of age, it is time to see an ophthalmologist. Treatment may include masking, eye drops, glasses and surgery. Visual impairment Some children cannot see distant objects (nearsightedness) or near objects (farsightedness). If the surface curvature of a child’s cornea is irregular (astigmatism), objects at any distance are blurred. The above common visual impairments in children can usually be corrected with glasses, corneal contact lenses, etc. If not effectively corrected, amblyopia can result. Ocular Inflammation and Eye Trauma Ocular inflammation and eye trauma are common in children. Viral or bacterial infections can be widely spread in classrooms and childcare centers. Children are active and can easily bruise their eyes, stain their eyes, or get foreign objects in their eyes. Eye inflammation and eye trauma must be treated early or permanent damage to the eye can result. Cataract】What is cataract? A cataract is a clouding of the lens in the eye. Treatment of cataracts Surgery is the only definitive and effective way to treat cataracts. If the cataract has not yet affected you significantly, you only need to replace a pair of glasses to feel comfortable, and no treatment is necessary. Treatment of retinal fissure and detachment】 What is retinal fissure and detachment? The retina is a layer of nerve tissue inside the eye that perceives focused light rays and sends them to the brain as signals to become the images we feel. Ageing, nearsightedness, eye trauma or other causes can lead to retinal tears or detachments. Learn how to know the pre-onset symptoms Many people have experienced flashes of light and floating objects in front of their eyes. Sometimes some of these symptoms may be signs of a retinal detachment or fissure. 1. a sudden increase in flashes or floaters in front of the eyes 2. loss or distortion of vision 3. loss of vision after blunt trauma to the eye. Diabetic retinopathy】 Diabetes will affect vision When you have diabetes, high blood sugar will damage the large and small blood vessels of the retina at the bottom of the eye, as well as the retinal nerve layer that senses light and transmits nerve impulses, causing a series of vascular damage to the retina, which is called diabetic retinopathy. Daily schedule of eye examinations for diabetic patients Diabetic patients should have an eye examination at least once a year. Those who have been diagnosed with diabetic retinopathy should have more frequent exams. Diabetic retinopathy can progress rapidly during pregnancy, so regular fundus exams should be performed during the first trimester of pregnancy. Make sure your blood glucose concentration has stabilized in recent days before fitting your lenses. If your blood glucose is not effectively controlled, it will lead to improper fitting of lenses that are not suitable for you to wear. Flying mosquitoes】What is flying mosquitoes? It is called mosquito flying syndrome when there are small flying mosquitoes or black shadows in front of your eyes. Is it serious? If the crumpled vitreous pulls on the wall of the eye, the retina can form a fissure. A small amount of bleeding in the fundus of the eye can also cause mosquito flying. 1, If you have symptoms of retinal fissure or detachment, please see your doctor immediately. 2, Early treatment is the only effective way to prevent vision damage.
