Eye Cataracts Surgery

Some older dogs, usually over 6 years of age can sometimes be prone to eye cataracts. There is another similar condition which can affect the dog’s eye also, known as nuclear sclerosis which causes a grayish colour of the eye lens.

A dog can have both nuclear sclerosis and an eye cataract at the same time, and it is for the owner of the dog to decide on whether the dog’s vision is being affected, in which case a cataract is suspect, since nuclear sclerosis does not affect vision.

A visit to a veterinary ophthalmologist will confirm if a cataract is present and dog eye cataract surgery may be recommended. But it should be understood by the pet dog owner that the cataract cloudiness is permanent and the only treatment is for cataract surgery.

The impact of having Macula Degeneration can be quite severe for any sufferer , and, when considering the importance of sight, can be difficult to adjust to.

Macular degeneration can have an emotional effect on the person in coming to terms with every day routines which suddenly, may cause a problem. If any macular degeneration sufferer is having a struggle with normal daily activities, and the disease is causing any mental complications in the person, then the advice of a doctor or AMD Support Group should be sought.

The optical nerve which is located at the back of the eye is the chief ‘seeing’ nerve of the optical system. This optical nerve then transmits the images it sees to the brain for translation into what is being seen. Lets discover a little about the eye.

Some Aspects of the Eye.

n  A healthy eye is form and round on shape.

n  The shape of the eye is maintained by a pressure within the eye called Intraocular Pressure.

n  For the correct tone, shape and function of the eye it is necessary for this eye pressure to be held at between arrange of 8 – 22 mm of mercury.

The eye lens focuses incoming light on the Retina (nerve cells) of the eye, which in turn pass on the signal to the brain, which interprets what is being seen.

The lens also adjusts its focus to the relative strength of the incoming light and discriminates between distant and close objects, it is normally clear and transparent, but sometimes becomes cloudy, which is the condition known as an eye cataract

But just what is it that makes the lens becomes cloudy, what is the cause of an eye cataract? Medical people who study cataracts are unsure about the absolute cause of the condition, but point to certain risk factors which are positively related to cataracts, they include—

Cataracts cause problems with the ability of a sufferer to see and focus properly, they are common in the aged, but can also affect younger people, and it is not unknown for a new born baby to suffer from an eye cataract. These kind of cataracts are commonly referred to as Congenital Cataracts.

As the cataract develops it leads to stoppage of the amount of light entering the eye lens, so limiting the amount of vision of the person . . .  no light . . . no see!!

If the cataract seriously impairs the vision of the sufferer then the removal of the cataract by surgical means is recommended

If a person is in the risk category for glaucoma, or indeed is experiencing any problems with her/his vision, especially peripheral vision, then a visit to the doctor is called for, because it could be an early sign of glaucoma, and a positive diagnosis is required.

The eye doctor or ophthalmologist will examine the patient who is at risk, for any signs of the filter angle narrowing, this is the angle between the eye cornea and iris, where the regulation of the drainage of the eye aqueous humor fluid occurs.

For any patient already suffering from glaucoma the doctor will check for the degree of damage to the optical nerve and how the patient’s vision has been affected. And then proceed with a series of tests.

Following eye surgery involving the removal of a cataract or refractive lens exchange, the ophthalmologist may recommend the insertion of a Crytalens.

The crystalens is a multifocus intraocular lens, (IOL) which unlike the more traditional monofocal lens, is designed to permit the user to have both close and long range vision, without the aid of eye glasses.

The Working Processes of a Crystalens.

Rays of light entering a monofocal lens are bent to a focus point and as the lens becomes stronger so the light is bent more sharply, the lens being monofocal can only focus the light at one point on the retina of the eye.

In the treatment for glaucoma, although both Laser treatment and Surgery are being successfully utilized, the use of eye drop treatment should not be forgotten.

It is a fact that in the USA the preference by doctors is to use eye drops for glaucoma treatment, whilst in Europe, the use of Lasers or surgery is the preference. Certainly the use of eye drops is a lot easier and less expensive than surgery, so are there any advances being made, in developing more effective eye drops for glaucoma treatment?

Photons of light enter the eye and impact on the adjustable Retina (eye lens), they then travel to the nerve tissue at the back of the eye ( Optic Nerve) and are transmitted to the brain, the light photons are translated, and so we see!

The condition known as Glaucoma describes a group of diseases that result in loss of vision by causing permanent damage to the optic nerve. It can lead to loss of central vision and eventual blindness if not diagnosed and treated at an early stage, but glaucoma can often come on suddenly without having any early indications until it is too late

In the dry form of macular degeneration it is recognized that antioxidant deficiency plays a role in the onset of age-related macular degeneration (AMD), and that for the wet form medicines, for treatment, are more readily available.

There are now a number of medications on the market both tried and tested, with newer medicines for macular degeneration now becoming available, all the time, some include the following.

Some Medications for Macular Degeneration.

Antioxidants. These nutritional additives play their part in reducing the chances of developing macular degeneration in people who are at high risk, Beta-Carotene with zinc and the intake of Vitamins C, E.
