The sense of sight is considered as one of the most vital senses needed for everyday living, and its degeneration would require extensive training of our other senses to make up for its loss of function. Thus, for centuries, humanity continuously developed and improved the field of medical eye care to adequately safeguard this wondrous sense of sight. From the use of basic lenses to simple surgeries, medicine has come a long way in alleviating various eye disorders. Now that we have reached the 21st century, it is incredible just how far the field of medicine has come in the aspect of eye care. Eye doctors in St. Louis MO are able to diagnose and treat eye problems better because of the advances in the field of optometry.
Light perception is one of the fundamental processes of the eye. Photoreceptors are the dominant player in this process and these function by sensing and processing the light that enters our eyes in a way that our brain would understand. Because of its crucial role, any anomalies in our photoreceptors can cause a variety of degenerative eye diseases. Photoreceptor anomalies may soon have a solution due to extensive research of the University of California which makes it possible to restore faulty photoreceptors to their normal condition. Their research demonstrated the introduction of a virus’ inactivated gene into a visual system. The ganglion cells of mice who suffered macular degeneration were used to test their study, and yielded great results as the animals’ vision was restored over time.
Aside from operative processes, the development of tools is also needed to enhance the eye care industry. Cameras are widely used tools in optometry to observe a patient’s eye and capture images for further study of their conditions. Sony, a massive multinational conglomerate, has developed a two-piece full HD video camera intended for surgery and has an ensemble of features. The camera works even in low light applications for operating light-sensitive eyes. The camera also has a high dynamic range (HDR) mode which enhances contrasts and colors to view wet tissues better and thus allows the optometrist to get more data in studying eye conditions.
Tools are not only for observing but for performing eye surgeries as well. In this aspect, modern technology does not disappoint. Surgical instruments are needed to insert drainage devices in the eye to get rid of excess fluids to treat diseases such as glaucoma. This procedure, however, does not guarantee success due to the build-up of microorganisms in the device which leads to its limited lifespan. An alternative drainage device was designed by researchers from Purdue University which uses external magnetic waves to clean itself up, thus enhancing its lifespan significantly. Its actuators vibrate to scrape its drain walls and remove blockages.
Eye care and the field of optometry has come a long way with the development of various tools and processes to observe our eyes and combat disorders better. And for many more years ahead, we can expect even greater things because optometry will surely reach even greater heights in research and development so future generations will no longer suffer from preventable eye diseases.
