Greetings to all and sundry,
It is another beautiful day today and a wonderful opportunity to come your way with yet another interesting topic concerning our ocular health for us to discuss. I do hope you enjoy our previous session on Ocular Deviation and that you learned a thing or two from it.
For out discussion today we would be looking at a very common disease that is a global headache and one of its effects its having on the eye. This particular condition of the eye is a leading cause of blindness and one that can easily be managed when uncompromised. So let's get right to it.
Diabetes is a global canker that health practitioners across the globe are doing so much to curb in terms of education and medicine. It is a condition where the body's ability to utilize glucose and save for later usage through conversion to storageable form is affected. This may come about as a result of anatomical anomaly during growth and development as in the case of type I diabetes or physiological malfuction through aging as in the case of type II diabetes.
This results in too much glucose been available in our blood. Glucose is naturally not meant to be in our blood in large quantities and so when this happens it tends to disrupt the entire system throwing cells and tissues into mayhem. Their concentration affect the movement of water and substances in and out of cells as the rules of Osmosis and diffusion stipulates.
This results in the death of cells and tissues over time, throwing our entire system off balance. Due to the fragile nature of the eye, the effect of diabetes also goes on to affect it in diverse ways one of which is our topic for discussion today, diabetic cataract. The eye naturally has a crystalline lens inside ought to remain transparent to enable us see well. As we grow older the transparency of this lens is affected as it becomes translucent and later on opaque.
This is known as senile cataract and takes years to progress, there are many individuals who never get to even experience a fully grown cataract in their eyes throughout their entire lifespan however when diabetes comes in things change drastically.
In diabetic Cataract what happens is that the senile process of cataract development is altered and accelerated drastically such that changes that would have been expected within a time frame of a decade could be seen in half a decade or even less depending on how well one may be managing their condition.
What happens is that the glucose which goes into the eye and the crystalline lens end up been converted to a more damaging form called sorbitol, under normal conditions and processes vitamin C and other antioxidants within the eye could have taken care of such reactions to make things better for the eye however due to the excess amount of glucose available they get overwhelmed and thus are not able to do much.
And so the sorbitol accumulates and causes the cells of the lens to break down and agglutinate thus resulting in opacity of the lens, As this process continues the opacity progresses until that point of matured cataract or morganian cataract is reached. At this point the lens liquifies and may end up mixing up with the vitreous humor and other liquids within the eye. This may make interventions difficult and more complicated.
This may result in loss of vision if not dealt with earlier, and for those who are lucky enough to have surgical intervention before this point is reached, they mostly end up with another condition known as posterior subcapsular opacity due to the glucose availability in excess. And so diabetes can very much be a headache for your eye and sight.
The management of diabetic cataract stems from the management of the systemic diabetes conditions since the cataract formation is more or less and side effect of the diabetes condition. Thus, management is team effort between your Optometrist, Your Ophthalmologist and Your general physician. You may be given some eye supplements filled with antioxidants to help combant the reactions that may be going on in the eye however most of the heavy lifting would have to be done by your general physician in managing your diabetes.
Any surgical intervention that may be needed would have to be dealt with by your Ophthalmologist and co-observed by your Optometrist. In the case of complications or the development of posterior subcapsular opacities you may need lasik surgery to help make things better. However, i am certain that at this point in time you would agree with me that managing your glucose level well may just make all the difference in keeping your eye from getting worse developing this condition generally.
As i conclude, i would like to once again say a big thank you to you my dear reader for spending your time to read what i had to share with you today. I look forward to seeing you around and as always feel free to ask questions or for clarifications. Stay safe and have a great weekend ahead.
