In this article we will talk about some serious eye conditions that should be treated professionally because it can lead to vision loss or even blindness. Eyes can show some small symptoms or no symptoms at all. Regular eye examinations are the best way to avoid these kinds of complications.
Cataract is the leading cause of blindness in the world. It appears as blurriness of the collection lens an it is visible even to the naked eye. At birth, each baby has completely transparent lenses, but over time, for various reasons the lenses begin to gradually lose their transparency and thus cause the vision reduction. This can be relatively mild and cause limited vision damage or it may significantly block the passage of light to the retina and cause severe damage of the eye.
There is a wide range of causes:
Aging is the most common cause and it often occurs after reaching 55 years. It represents the 90% of all cataract diseases. It is considered to arise as a consequence of disturbance in the metabolism of the lens which causes the reduction of its transparency and therefore affects the vision. Old age cataracts are progressive and if they are not treated correctly they may lead to terrible vision loss and disabilities.
It can also be a children’s developmental anomaly which occurs after certain infections of the mother during pregnancy. This is known as the congenital cataract.
It can also occur due to a long-term exposure to ultraviolet radiation by spending a lot of time outdoors without the use of UV protective sunglasses, especially in the summertime.
It may occur as the secondary effect of certain diseases such as diabetes also known as diabetes mellitus.
Trauma and eye injuries may also be the cause.
The main symptoms are:
Light scattering and gently sparkling of everything around the patient;
Faded colors and increased amount of the yellow color;
Difficulty with vision during night;
Sensitivity to glasses of or contact lenses;
The only treatment method is the surgery or the phacoemulsification of the cataract. It is performed by removing the blurred lens using the ultrasound and the installation of an artificial lens in its place.
Cornea problems and diseases
The cornea is located in the middle of the eye in front the pupils. Its transparency is caused by its special material. A healthy cornea allows light rays to break deep inside the eye until it reaches sensory cells of the eye which is located at the bottom of the retina. Most corneal diseases leave a trace in form of blurriness. Blood vessels are infiltrating the corrupted cornea which is reduces their transparency.
It occurs most frequently during the haymaking season due to various injuries. The eye blushes and becomes narrow and painful. Improper treatment of this problem often leads to the loss of the eye.
Deep inflammation of the cornea
It occurs due to a variety of disease but the most common cause is the hereditary syphilis. It occurs in childhood or in young ages. Often it begins with one eye then the other eye gets infected. Eyes cannot tolerate light, tears occur more often and the corona gets blurred. The treatment usually lasts around six weeks. It leaves a considerable blurring of the cornea. To prevent this disease, syphilis should be treated in time especially with pregnant women. This disease can easily get transmitted to the fetus through the blood.
People who are working in metallurgy and stone processing industries are the common patients. These injuries leave traces in the form of opaque corneal scars. This disease may be prevented by wearing protective eyewear. Extraction of foreign bodies from the eye should be performed by a qualified person.
This is a condition that causes damage to the optic nerve of the eye that can get worse over time. It I often associated with an accumulation of pressure within the eye. Glaucoma tends to be hereditary.
Increased intraocular pressure can damage the optic nerve which transmits images to the brain. If the pressure continues it can cause permanent vision loss. The common causes of glaucoma are mechanical or chemical injuries to the eye which leads severe eye infections, blockage of blood vessels in the eye, inflammatory conditions of the eye and sometimes to laser vision correction.
