Hi, I need to know that is it possible to transplant cornea within living person. Like I want to donate it to my husband, as he had an accident. Please advise.
Water comes out from my eyes off and on. I am now using eye lotion "TEARS NATURAL" It is helping. My question is whether I shall continue with this lotion.
Total or partial opacification of transparent lens of the eye is termed as cataract. Such opacification essentially occurs in old age but it can occur in children or young age due to diabetes, trauma, congenital causes, use of steroid drops in the eyes or secondary to glaucoma.
Cataract affects vision depending upon its degree and location. Very slight cataract at the posterior pole can obstruct central vision and cause marked glare blindness or inability to read small letters whereas, cataract in the cortical area may take long time to affect vision.
Treatment: no medicines can cure cataract. Once it occurs, it has to be operated.
When to get operated?
When you are professionally blind or unable to carry out your routine duties/work. A driver or a watch repairer has to operate very early due to glare blindness whereas an old lady can wait for some time. It is ideal to get the surgery done with immature or early cataract than to wait for the cataract to get mature. A mature or hypermature cataract is difficult and risky to operate.
Phacoemulsification with ultrasonic rays is the modern method os surgery. You get only 2-3 mm of an incision, no sutures. The lens is emulsified and aspirated and a foldable IOL (lens) is injected by a syringe which unfolds and occupy the same space as your original lens. 10 minutes surgery with practically no pain. This lens lasts for a life time and gives you youthful vision.
The surgery can be performed even in patients with diabetes or hypertension and at any age. Maybe 90-100. Practically no post-op restrictions.
I feel my left eye like blur I can see anything which is near to me but I see like blurry when something is far to me Only in left eye Whats is the reason? And how I can prevent?
Eye flashes or photopsia can be caused by many conditions. Although flashes are harmless, they might indicate some serious eye issue which needs to be addressed immediately. Medical attention should be taken when flashes cause loss of vision and also small spots seem to float from one side to the other, thereby hindering the vision.
Migraines and very severe recurrent form of headaches which last for few hours to many days can cause visual symptoms. The light flashes look like zigzag lines, geometric patterns and sparkles when they occur with a migraine. Flashes might affect one eye or both and occur in the peripheral area of the vision. Light flashes sometime also occur due to ophthalmic migraine, a migraine without a headache.
Posterior Vitreous Detachment
The jelly like substance or the vitreous fluid fill the center of the eye and also gives it shape, is attached to the retina. With age and over time there is shrinking of the vitreous and it begins to detach from the retina. This is known as posterior vitreous detachment. In this the vitreous tugs or pulls on the retina, while the retina gets detached and stimulates it thus causing flashes to occur.
There is no known treatment for posterior vitreous detachment, through regular monitoring of the eye through eye checkups are helpful. Symptoms of this are similar to those of retinal detachment (condition in which there is permanent vision loss).
Retinal Detachment or Tear
Retinal tear and detachment also cause light flashes in the eye. This needs to be treated promptly. In case of permanent vision loss there is detachment of retina at the back of the eye, especially if the detachment takes place over the macula which is the main focus of the vision on retina. When the retina detaches from the eye, it loses the main source of nutrients. As there are photosensitive cells in the retina which are responsible for vision, the results of retina tear are severe.
Retinal damage occurs after trauma or as a complication from diabetes or posterior vitreous detachment. Vitreous gel tends to seep under the retina from the small crevices and holes formed by the retinal thinning. This in turn raises the sections and disconnects it from the eye. This can be corrected by laser treatment, cryopexy or an eye surgery.
A trauma like a hard blow on the head can lead the person to experience flashes of light. Also some medications can lead to toxic levels, like Digitalis can cause flashes of light. The symptoms of eye flashes also occur with macular degeneration, which is an age-related disease and in this the vision reduces gradually.
