I want to ask a question that I am suffering from a disease called myopia so it is compulsory to wear concave glasses all the time.
I always feel heaviness in my eyes. Not sure whether it is related to any allergies or any other medical condition. Please suggest what is the right step to get it diagnosis.
I have rough area over my eyelids which are itchy from last 3-4 yrs. My brother has psoriasis in his legs. Is this the same. What should I do?
Age-related macular degeneration, also known in brief as AMD or ARMD is one of the most common age-related causes for vision loss. It causes “blind spots” in vision, causing difficulty in activities requiring central vision like reading, sewing, driving, watching TV, computer usage, etc.
How it happens?
The centre portion of the eye is known as retina which has a screen in the posterior portion. For proper vision, light falls on this screen and is then processed to enable ‘vision.’ When this screen is not clear, blurred vision results. It may not cause total blindness but impairs vision including double vision and loss of central vision.
Types: There are two types of AMD, wet and dry.
- Dry: There are yellow deposits known as drusen which form in the macula, and as they grow in size, they impair vision, specifically the central vision. This is the common variant and can lead to the wet form.
- Wet: There are abnormal blood vessels which are formed in the retina. There is leaking of blood and fluid which makes it ‘wet.’ There could be scarring of these leaked substances, which again leads to loss of central vision. Further studies have shown that retina produces a protein knows as vascular endothelial growth factor (VEGF) which promotes the generation of new blood vessels, normally required for the production of new blood vessels. However, increased VEGF causes excessive proliferation of blood vessels, leading to macular degeneration.
Risk factors: Though age related, there are definitely some factors which put one at a higher risk for AMD
- Genetics: AMD is hereditary and runs in families
- Gender: Females are more prone to develop AMD than males
- Ageing: People above 60 are at greater risk
- Smoking: Direct and passive smoking contribute to AMD.
- Obesity: Accelerates the pace of AMD and severity of complications.
- Hypertension: Increases the chances of developing AMD
- Ethnicity: Caucasians are more prone to develop AMD as their lighter skin and eye color is more prone to sun damage
- Sun exposure: Increased sun exposure accelerates the onset of AMD
- No symptoms in the initial stages
- Gradually, there is impaired central vision, affecting activities like reading, driving, and computer usage
- Color perception is impaired
- A routine eye exam will reveal the yellow deposits which actually cause the condition.
- An angiography may be done after injecting a dye to detect blood vessel growth.
There is no cure, but progress can be delayed
I have head pain in back of the head in left side, eye concentration lost and balance losing. What is the reason and remedies?
Im suffering from cold for last 1 month. I do feel itching inside nose as well as eyes. Because of that im getting sneeze several times. What I have to do to get rid of this. I am not able to sleep also.
My eyes always start watering when I sit on PC as I have a very big number in my eyes but it s impossible to work without PC nowadays Every work is on PC but I had squint in my eyes and I always had headaches . So is there possibility of vision loss. I have two different numbers in my eyes.
Retinal detachment is an emergency eye condition in which the retina at the back of the eye gets separated from the surrounding tissue and pulls away from its normal position. The retina acts as a light-sensitive wallpaper in the eye, providing a lining for the inside of the eye wall and sending visual signals to the brain. As the retina can't work properly under these conditions, one can permanently lose vision if the detached retina is not repaired immediately.
During the retinal detachment, the retinal cells gets separated from the layer of blood vessels which provides oxygen and nourishment. Usually, it begins in form of small torn area of retina known as retinal tears or retinal breaks. This condition, if not treated, leads to retinal detachment and finally permanent vision loss.
Retinal detachment has tell-tale warning signs like an increase in sudden appearance of floaters resembling cobwebs floating in field of vision. It can be coupled with flashes of light or curtain from any direction causing a loss of vision.
Retinal detachment is of three types. The most common form is Rhegmatogenous retinal detachment where a tear allows fluid to get under retina and prevents nourishment to reach retina from retinal pigment epithelium by separating them. In Fractional form, scar tissue on the retina's surface shrinks causing it to separate from the retinal pigment epithelium. This form is most prevalent with diabetes patients. Lastly, in case of Exudative retinal detachment, the fluid leaks into the area under retina without a tear or breaks in the retina. Retinal diseases or trauma to the eye are main causes for Exudative retinal detachment.
Although a person of any age can suffer from retinal detachment, but it is more prevalent in people over the age of 40. People suffering from degenerative myopia or lattice degeneration are more prone to this medical condition. People with family history of retinal detachment are also likely to suffer from the same.
Retinal detachment can be treated in many ways. The most common form is the Laser surgery in which small tears and hole are joined back to the retina. Another method is Cryopexy in which the area around the hole in frozen and helps reattach the retina. Both the above procedure are performed at ophthalmologist's clinic.
Sometimes, one may have to opt for Scleral buckle in which a tiny synthetic band is attached to the outside of the eyeball which gently pushes the wall of the eye in toward the centre of the eye placing the eye wall very close to the detached retina. Another option is vitrectomy surgery to replace the vitreous that fills the centre of the eye and helps the eye maintain a round shape.
A retinal detachment is an emergency medical condition and must be treated immediately to save one's vision. Most people have been successfully treated for retinal detachment, but ophthalmologists cannot always predict how vision will turn out. The visual outcome will not be known for up to several months after surgery. However the results are best when the retinal detachment is treated as soon as possible.
