Environmental changes and unhealthy lifestyles are just two of the several factors that could contribute to the quicker pace of macular degeneration and vision loss among many people. Aside from these, dysfunctions in the workings of the human anatomy can also lead to contractible eye illnesses. Megan Fellman of Northwestern University reported on the results of a recent study along this line of inquiry:
In a unique study of human ocular cells, a multi-institution research team led by a biomedical engineer at Northwestern University has found a new culprit. Glaucoma appears to be a consequence of mechanical dysfunction of endothelial cells — a thin layer of cells that is the final barrier to fluid entering Schlemm’s canal, from which fluid then drains from the eye.
The researchers found that these endothelial cells from eyes with glaucoma are stiffer than cells from healthy eyes. This stiffness limits the cells’ ability to deform and allow a fluid called aqueous humor to cross the endothelium and drain into Schlemm’s canal. This increased flow resistance is responsible for the elevated pressure associated with glaucoma.
Caring for one’s eyesight and checking for disorders in the body are not mutually exclusive as both aim to preserve the healthy state of human eyes and even induce improvements in the sense organ’s condition. Moreover, examinations are pretty simple and are relatively direct. This is why people should not hesitate to approach a trusted optometrist, such as Penn Moody, OD of Moody Eyes, for a comprehensive eye exam in Indianapolis.
Eye doctors would normally ask patients first about their medical history and if there are any vision problems or changes. After this, various tests will be performed, including those that check for visual acuity, eye pressure, and other aspects of vision; the results of these can determine if patients’ eyes are in good health or are at risk of vision degeneration and blindness.
If problems are detected early, qualified optometrists may prescribe eye drops or the use of glasses, contact lenses, and other aids which could help patients manage their eye problems. However, while optometrists will exhaust all available methods of eye care in Indianapolis to ensure that their patients continue to enjoy good vision, people also need to understand that they need to regularly go for eye exams as this is the most accessible first step in preventing blindness.
