Myopia surgery is usually done in people with a degree of myopia stabilized and who do not have other more serious problems in the eye, such as cataracts, glaucoma or dry eye, for example. Thus, the best candidates for this type of surgery are usually young adults over 18 years. Although there are different techniques of surgery, the most used is laser surgery, also known as Lasik, in which a light ray is used to correct the cornea, and can be used to definitively cure myopia up to 10 degrees

Spending cold compresses in the eyes or washing the eyes with cold water are natural and homemade options to reduce and treat the symptoms of allergy in the eyes. Eye allergy consists of an inflammatory reaction to an irritant that has come into contact with the eye, such as dust, makeup or face creams, for example

Difficulty in seeing, severe eye pain or nausea and vomiting are some of the symptoms that high pressure in the eyes can cause, an eye disease that causes progressive decrease of vision. This is due to the death of the optic nerve cells and the disease can even cause blindness if not treated from the beginning when the initial symptoms appear

The cyst in the eye are rarely severe and usually indicate inflammation, being characterized by pain, redness and swelling in the eyelid, for example. Thus, they can be easily treated only with the application of warm water compresses, to alleviate the symptoms of inflammation, which should be done with the sanitized hands

Ocular effusion, or hyposphagma, is characterized by the breaking of tiny blood vessels located in the conjunctiva, causing a red blood stain on the eye. The conjunctiva is a thin transparent film that covers the white part of the eyes called the sclera. The effusion in the eye is a fairly common situation that does not reach the inside of the eye, not affecting vision

Myopia is a disturbance of vision that causes difficulty in seeing objects from afar, causing blurred vision. This change happens when the eye is larger than normal, causing an error in the refraction of the image taken by the eye, that is, the formed image becomes blurred. Myopia has a hereditary character and the degree usually increases until it stabilizes around 30 years, regardless of the use of glasses or contact lenses, which only correct blurred vision and do not cure myopia

Optic neuritis, also known as retrobulbar neuritis, is inflammation of the optic nerve that prevents the transmission of information from the eye to the brain. This happens because the nerve loses the myelin sheath, a layer that lines the nerves and is responsible for the transmission of the nerve impulses

Flying flies are dark spots, resembling filaments, circles or webs, that appear in the field of view, especially when you see a clear picture, such as a white paper or a blue sky. Generally, flies in the eye appear with aging, due to flaws in the vitreous, which is the gelatinous part of the eye, however, can also occur in young patients due to small retinal detachment points, which although not detrimental to the vision, form lumps that can float in the liquid of the vitreous, and form shadows that are projected onto the retina

Retinal detachment is an emergency situation in which the retina is detached from its correct position. When this happens, a part of the retina no longer has contact with the layer of blood vessels in the fundus of the eye and, therefore, the retina stops receiving the necessary amount of blood and oxygen, which can result in tissue death and blindness

Bitot's spots are grayish-white, oval, foamy, irregularly shaped spots on the inside of the eyes. This spot usually arises due to the lack of vitamin A in the body, which leads to an increase in the concentration of keratin in the conjunctiva of the eye. Lack of vitamin A is usually characteristic of a condition called xerophthalmia or nocturnal blindness, which is an inability to produce tears and difficulty seeing, especially at night

Myopia, astigmatism, and farsightedness are eye diseases that are very common in the population, which are different from each other and can still happen at the same time in the same person. While myopia is characterized by a difficulty in seeing objects from a distance, hyperopia consists of the difficulty of seeing them closely

The eye bug, also known as Loa Loa or Loiasis, is an infestation caused by the presence of Loa loa inside the eye, causing symptoms such as irritation, pain, itching, and redness. Generally, the larva is released when the mango fly, very common in some regions of Africa, repeatedly bites the skin, depositing larva eggs in the blood

Cataract surgery is done to treat congenital cataract, which is where the baby is born with damage to the lens or acquired, which is characterized by progressive loss of vision, and is a consequence of aging. Learn more about cataract. Surgery is a quick and simple procedure and usually has no risks or complications

The white spot on the eye, also called leukocoria, appears more often in the pupil and may be indicative of serious diseases such as retinoblastoma or congenital cataract. The causes of white spot in the eye can be identified right at birth through the test of the little eye, which is a test performed at the maternity hospital provided by SUS

Knowing the type of conjunctivitis in question is very important to perform the treatment correctly and prevent the worsening of the disease. The most commonly used remedies are eye drops for conjunctivitis, which must be used under medical prescription. Some tips for treating conjunctivitis are: Keep eyes clean and dry; Use sterile saline to wash the eyes; Wear disposable tissues or wipes to dry the eyes; Wash hands with soap and water several times a day and always before and after cleaning eyes; In addition, you should also avoid sunlight and wear sunglasses whenever you leave the house

Treatment for adult strabismus is usually initiated with the use of glasses or contact lenses to correct vision difficulties that may be causing or aggravating the problem. However, when this type of treatment is not enough, the ophthalmologist may recommend doing eye exercises once a week in the hospital, and daily at home, to improve coordination of the muscles and help focus the objects better

The eye exam, or ophthalmological exam, is to evaluate visual ability and, although it can be done at home, should always be done by an ophthalmologist, since only he can make a correct diagnosis and evaluate the health of the eyes. There are several types of eye exam, however, the most common is the examination to assess the ability to see from near and far and should be done at least once a year from the age of 40, even if you already wear glasses, because the degree of the glasses may have changed, needing to be increased or decreased depending on the case

A small scratch on the cornea, which is the transparent membrane that protects the eyes, can cause intense eye pain, redness and tearing, and it is necessary to use cold compresses and medications. However, this lesion is usually not severe and will stop within 2 or 3 days. This type of injury, also known as corneal abrasion, can happen if there is any foreign body in the eye

Glaucoma eye drops have the function of reducing blood pressure in the eyes, and should be used throughout life to control the disease and prevent its main complication, which is blindness. However, although they help control the disease, eye drops also cause various side effects such as headache, drowsiness and itching, but it is important to continue using the medication correctly until you see your ophthalmologist to see if you can make changes to the treatment

Keratoconus is a degenerative disease that causes deformation of the cornea, which is the transparent membrane that protects the eye, making it thinner and curved, acquiring the shape of a small cone. Generally, keratoconus appears around the age of 16 with symptoms such as difficulty seeing at close range and sensitivity to light, which occur due to the deformation of the eye membrane, which ends up blurring the light rays inside the eye
