A cataract is any opacity of the eye’s natural lens (crystalline), which is usually transparent. There are many types of cataracts. Some are small and do not affect vision; others are big and cause severe loss. Its incidence varies all over the world.
Cataract is the loss of transparence in crystalline (natural intraocular lens) whose function is to focus light in the retina. This “cloudiness” limits vision and may lead to blindness if not treated in extreme situations. Cataracts generally developed slowly and are pain-free. For this reason, vision and daily life may be affected without any sign.
To enable a sharp vision, light rays from an object placed in the visual field must converge to a single point of retina. The eye works like a camera – it has an opening in the front part (pupil), a focus mechanism (cornea and eye lens) and a light-sensitive portion in the back part (retina). Eyes affected by significant refractive errors such as myopia, hyperopia and astigmatism are not capable of focusing light in the intended retinal region.
A Oftalmologia é única entre as especialidades médicas. O olho, as suas estruturas circundantes e as vias visuais podem ser afetados por uma grande variedade de patologias. A sua resolução bem-sucedida requer muitas vezes capacidades diagnósticas e terapêuticas de um médico, bem como as habilidades técnicas de um microcirurgião, reunidas numa pessoa com o entendimento global e integrado do todo do doente. A oftalmologia é portanto uma especialidade médico-cirúrgica.
Strabismus is associated to any kind of eye misalignment. There are many different types of strabismus and they are usually described according to the direction of the deviation. The most common types are endotropia (convergent deviation), esotropia (divergent deviation) and hyperopia (vertical deviation). Special strabismus patterns can have unique names, such as Brown syndrome and Duane syndrome.
Amblyopia is a decrease in visual function in one or both eyes due to an abnormal ability of the visual pathway during childhood. Amblyopia does not necessarily imply an obvious problem in the eye. Vision loss occurs when neural pathways between the eye and the brain are not properly stimulated during recommended age.
