 Uveitis
The uvea is the middle layer in the eye sandwiched between the retina (innermost layer) and the sclera (outermost layer). The uvea contains many blood vessels that carry blood to and from the eye. Uveitis is inflammation of the uvea. Since the uvea nourishes many important parts of the eye, uv ...
- Age-Related Macular Degeneration
Age-related macular degeneration (AMD) is one of the most common causes of poor vision after age 60. AMD is a deterioration or breakdown of the macula. The macula is a small area at the center of the retina in the back of the eye that allows us to see fine details clearly and perform activities ...
- Proliferative Diabetic Retinopathy
Proliferative diabetic retinopathy (PDR) is a complication of diabetes caused by changes in the blood vessels of the eye. If you have diabetes, your body does not use and store sugar properly. High blood sugar levels create changes in the veins, arteries, and capillaries that carry blood throug ...
- Epiretinal Membrane
The retina is a layer of light-sensing cells lining the back of your eye. As light rays enter your eye, the retina converts the rays into signals that are sent through the optic nerve to your brain, where they are recognized as images. The macula is the small area at the center of your retina ...
- Laser Surgery of the Eye
The word “laser” is an acronym for Light Amplification by Stimulated Emission of Radiation. A laser is a concentrated beam of light, created when an electrical current passes through a special material. Used in eye surgery since the 1970s, the laser is popular for its unparalleled d ...
- Detached and Torn Retina
A retinal detachment is a very serious problem that usually causes blindness unless treated. The appearance of flashing lights, floating objects, or a gray curtain moving across the field of vision are all indications of a retinal detachment. If any of these occur, see an ophthalmologist (Eye M ...
- Nonproliferative Diabetic Retinopathy
If you have diabetes mellitus, your body does not use and store glucose properly. Over time, diabetes can damage blood vessels in the retina, the nerve layer at the back of the eye that senses light and helps to send images to the brain. The damage to retinal vessels is referred to as diabetic ...
- Floaters and Flashes
Small specks or clouds moving in your field of vision as you look at a blank wall or a clear blue sky are known as floaters. Most people have some floaters normally but do not notice them until they become numerous or more prominent. In most cases, floaters are part of the natural aging proces ...
- Macular Edema
Macular edema is the swelling of the macula, the small area of the retina responsible for central vision. The edema is caused by fluid leaking from retinal blood vessels. Central vision, used for reading and other close, detail work, is affected. Because the macula is surrounded by many tiny ...
- Retinopatía Diabética Proliferativa
La retinopatía diabética proliferativa es una complicación de la diabetes causada por cambios en los vasos sanguíneos del ojo. Si usted tiene diabetes, su cuerpo no utiliza o almacena al azúcar de manera apropiada. Altos niveles de azúcar en la sangre c ...
- Retinopatía Diabética No-Proliferativa
Si usted tiene diabetes mellitus, su cuerpo no utiliza o almacena el azúcar de manera adecuada. A medida que avanza la enfermedad, esta puede dañar los vasos sanguíneos de la retina (la membrana nerviosa localizada en la parte posterior del ojo que percibe la luz y ayuda a ...
- Angiografía con Fluoresceína
La angiografía con fluoresceína es un examen clínico para observar la circulación de la sangre en la parte posterior del ojo, como también para diagnosticar condiciones de la retina relacionadas con la diabetes, la degeneración macular debida al envejec ...
- Manchas Flotantes y Centelleos
Las pequeñas partículas o nubes que se mueven en el campo de la visión cuando se mira hacia una pared desocupada, o hacia el cielo azul, se conocen como manchas flotantes. La mayoría de las personas experimentan esta condición, pero no lo notan hasta que las m ...
- Degeneración Macular Relacionada con la Edad
La Degeneración Macular Relacionada con la Edad (DMRE) es una de las causas más comunes de mala visión después de los 60 anos de edad. DMRE es un deterioro de la mácula. La mácula es un área pequeña localizada en el centro de la retina, en ...
- Vitrectomy Surgery
Vitrectomy is a type of eye surgery used to treat disorders of the retina (the light-sensing cells at the back of the eye) and vitreous (the clear gel-like substance inside the eye). It may be used to treat a severe eye injury, diabetic retinopathy, retinal detachments, macular pucker (wrinklin ...
- Toxoplasmosis
Toxoplasmosis is a common parasitic infection. When contracted by a pregnant woman, toxoplasmosis can pose serious risks to the unborn baby. Simple precautions can reduce the chance of infection. Pregnant women should avoid handling litter boxes and eating raw meat because the parasite may or ...
- Stargardt's Disease
Stargardt’s disease is an inherited disease that affects the retina, the layer of light-sensitive cells lining the back of the eye. It usually becomes apparent between the ages of eight and 14. Boys and girls are equally susceptible and more than one child in a family can have it. Starga ...
- Retinoschisis
Retinoschisis is a genetic eye disease that splits the retina, the light-sensitive layer of cells lining the back of the eye. It occurs in two forms, one affecting young children, the other affecting older adults. Both forms usually affect both eyes, though one eye may be worse than the other. ...
- Retinopathy of Prematurity
Retinopathy of Prematurity (ROP) damages premature babies’ retinas, the layer of light-sensitive cells lining the back of the eye. ROP usually occurs in both eyes, though one may be more severely affected. The last 12 weeks of a full-term pregnancy are an especially active time for the g ...
- Retinoblastoma
Retinoblastoma, a malignant tumor that grows in the retina, the layer of light-sensing cells in the back of the eye, can destroy a child’s vision and be fatal. Retinoblastoma can occur in one or both eyes, and usually develops in the first year or two of life. It affects children of all r ...
