|Description: It is the partial or total opacity of the lens. Opacity causes light to scatter inside the eye and cannot be focused on the retina, creating diffuse images. It is the most common cause of surgically treatable blindness. It has various causes but it is mostly attributed to age although there are many other causes as well. Over time, yellow-brown particles are deposited that gradually opacify the lens.
|Treatment: Different surgical techniques to remove the cataract and restore transparency in the crystalline lens.
|Symptoms: Few until its final stage. Loss of peripheral vision beginning at the nasal heel progressing to tunnel vision.
|Description: Increase or pathological variations of intraocular pressure, due to lack of drainage of the aqueous humor and has as a common final condition an optic neuropathy that is characterized by the progressive loss of nerve fibers of the optic nerve and changes in its appearance. Hereditary.
|Treatment: Antiglaucoma. It requires strict follow-up through tonometry (tension measurement), Retinography (evaluates optic neuritis) and Perimetry (Visual field to evaluate the peripheral field and other signs).
|Symptoms: In an initial stage, images with slight deformations are appreciated and progressively scotomas (black spots) are generated in the central visual field. Loss of central vision. Difficulty recognizing faces.
|Description: AMD or Age-Related Macular Degeneration is a degenerative disease of the central area of the retina, or macula, which causes a progressive deterioration of the cells and the retinal pigment epithelium. Age, smoking, genetic predisposition or hypertension are risk factors.
|Treatment: Control risk factors such as hypertension, cholesterol and smoking. Lead a healthy life. Drugs.
