Enter the universe of Eye Disorders and learn more about some of the most common issues that affect the way we see the world.
What is myopia?
It is a refractive error of the eye where images are focused in front of the retina.
Patients with myopia can see clearly close objects while distant objects appear to be blurry.
What is Hypermetropia?
It is a refractive error of the eye where images are focused behind the retina.
Although this condition tends to make images appear blurry regardless of their distance, young people may make up for long-sightedness by making the crystalline lens more converging through the process of accommodation although short-sightedness remains.
What is astigmatism?
It consists in a refractive defect of the eye, which is a result of different levels of refraction in different meridians.
What is presbyopia?
It is the progressive incapacity of focusing on close objects as a result of a decrease in the power of accommodation, which is directly related to age.
This difficulty is usually felt between the ages of 40 and 45 and will deteriorate throughout life until you reach 60, when this capacity of accommodation will be practically null.
What are cataracts?
Cataracts are opacities in the crystalline lens causing a decreased eyesight.
What is a glaucoma?
A glaucoma is a disorder of the optic nerve, which usually progresses with increased intraocular pressure (above 21 mmHg), changes in vision, and excavated papilla in the optic nerve.
Although there are cases of glaucoma with normal intraocular pressure, this is undeniably the most important factor for this disease to appear and progress.
What is diabetic retinopathy?
Diabetic retinopathy and subsequent complications are the main cause of blindness in western countries.
In terms of pathophysiology, it is equivalent to a microangiopathy (small vessel disease) reaching several body organs, including the kidneys, heart, nervous system, and eyes.
What is AMD?
AMD is a common disease that usually starts after the age of 60 and reaches the central vision keeping the peripheral vision unchanged. But given the fact that the central vision (the macula) is that which allows for us to have a clear view, our eyesight decreases deeply.
It appears as an ageing process (degeneration) of the bodily tissues.
