In our life, the value of eye is immense and it gives us the opportunity to keep all such eventful images of life around us in our memory, as captured by our eye all the time. The quality of life solely depends on the quality of our vision and without it all colors of life goes. So we should have some basic idea about our eyes i.e.(i) its structure & basic functions, (ii) eye related problems & its available treatments etc.
Eye is a very complicated optical organ of our body and it consists of three main types of tissues i.e. i) Refractive tissues, that collectively focus lights onto the light sensitive tissues and the "Cornea, Anterior chamber, Iris, Pupil, Lens" etc. are mainly known as refractive tissues.
ii) Light sensitive tissues, that detects the light & converting it into electrical impulse, sends to brain through optic nerve for further processing to produce image and these contain "retina, Macula & the optic nerve.
iii) Supporting tissues, that provide necessary assistance to all functional tissues in order to maintain the structural & functional stability, as well as retains metabolic requirements of eye, too and this include "Sclera, Ciliary muscle, Conjunctiva, Choriod, Aqueous humor, Vetreous humor, Uvea" etc.
As I have stated above, it is mostly the basic structural information of eyes and all the constituent parts in the structure collectively perform their functions in systematic manner under ideal conditions. But we can not expect ideal conditions all the time throughout our life, rather in todays complicated world,we have to come accross many such situations as is not favourable to our eyes, reulting in various eye problems some of which are as mentioned below.
i) Age-Related Macular Degeneration
ii) Amblyopia
iii) Cataract
iv) Diabatic Ratinopathy
v) Glaucoma
vi) Refractive Errors
vii) Strabismus.
Amongst eye problems mentioned above, cataract is the most dangerous complication of human eyes today which may make an individual completely blind if it is kept untreated for long. Specially, those who are diabetic patient, they mostly become the victim of this silent killer and offently, loss their eyes unknowingly. In addition to the above, "Age-related Macular Degeneration" is another matter of concern for diabetic elderly people, especially those who are already suffering from cataract.
If we look at the status of optical dissorders worldwide during last 14yrs, we will find around 32million blind in the year 2010 and surprisingly, one in three blind people found suffered from cataract. Additionally, in consideration to the cosistant progress of the said disease, world health organization (WHO) predicted that figure of blindness to reach around 90 million throughout the world by the year 2010 onwoards and this situation will remain unaltered.
Actually today this deases of cataract can't be treated by any other means except the surgery which requires an appropriate infrastructure and also it is very costly. Besides, our world, is not so symmetrical at all in economycal & developemental perspective, as it looks like, rather the dissparity amongst developed, developing or under developed countries are clearly seen which affects the life of common people. Consequently, most of the progresses in medical science, can't reach to the people of every countries in equal proportion throghout the world and that's why, large number of cataract effected common people remain incapable to take the benefits of costly advanced surgical treatment which ultimately, leads them to blindness.
Therfore in this article, I will try to concentrate myself basically on the subject of cataract effected elderly people and to findout the available possibilities of medicinal treatments of cataract instead of ongoing surgery.
