Macular Degeneration Effects Reduced by Brain Stimulation

 

The University of Waterloo’s School of Optometry found that brain stimulation can assist in recovery of vision in people with macular degeneration. A single 20-minute session of non-invasive visual cortex stimulation resulted in improved effects in macular degeneration patients.

Peripheral vision is relied on heavily by people who suffer from macular degeneration, as they often lose central vision. When attempting to crowd or segregate an object from others in close proximity, further difficulties arise.

Transcranial direct current stimulation (tDCS) interventions reduce mechanisms in the visual cortex that contribute to crowding. This can improve vision in patients with central vision loss, especially when combined with perceptual learning techniques.

Ben Thompson, professor at the School of Optometry and Vision Science, said, “Perceptual learning can reduce letter crowding for patients with macular degeneration. However, perceptual learning typically requires intensive training, which may be a barrier for patients. Additionally, the learning does not always transfer to non-trained stimuli, that’s why this discovery is so promising, it addresses all of these concerns. Results of this study lay the foundation for future work investigating whether a-tDCS may be useful as a visual rehabilitation tool for individuals with central vision loss who are reliant on peripheral vision.”

Macular Degeneration is the leading cause of vision loss (more than cataracts and glaucoma combined), affecting more than 10 million Americans. It is considered an incurable eye disease caused by the deterioration of the central portion of the retina. The retina is the inside back layer of the eye that records the images we see and sends them to the brain via an optic nerve. The macula, the retina’s central portion, is responsible for focusing central vision in the eye. It also controls our ability to read, drive a car, recognize faces, colors, and see objects in fine detail.

There are three stages of macular degeneration, with vision loss as the last. Despite there being no cure for macular degeneration, activities such as dieting, exercising, avoiding smoking, and protecting your eyes from ultraviolet light are all ways to decrease the overall risk.

How to Cope with Mask-Associated Dry Eye (MADE)

With the COVID-19 pandemic among us, expert and government recommendations have prompted mandates for face mask use in addition to social distancing. The use of face masks helps thwart coronavirus transmission. As the world emerges from shutdowns and the season changes from summer to winter, the imposed use of face masks for extended periods will increase.

To combat the spread of COVID-19, these preventative measures are essential. However, a new phenomenon is emerging: increasing reports of dry, uncomfortable eyes. Is there a science behind this trend, who is at risk, and what are the solutions?

Mask-Associated Dry Eye (MADE) was first described in June by an ophthalmologist who noticed an increase of these patients. A study published in July examined the issue further. Existing dry eye disease patients report worsening symptoms. Previously asymptomatic people are now complaining of dry, uncomfortable eyes, accompanied by inconsistent vision. These symptoms seem to occur most when reading or using digital devices for an extended amount of time.

Face masks drastically reduce the outward spread of air from the mouth and nose; however, exhaled breath still needs to diffuse. Masks that fit loosely against the nose cause the airflow to extend upward, forcing a stream of air over the surface of the eye. Those who wear glasses are familiar with this effect, as lens-fogging often occurs when a mask is worn. This repeated cycle can lead to dry eyes when masks are worn for extended periods. People who insert contact lenses daily are especially susceptible to dry eye since the ocular surface is already compromised by the lens.

There are a few ways to alleviate MADE. First, ensure your face mask fits appropriately, especially when wearing glasses. For prolonged use, consider applying athletes’ tape along the top edge and nose area. Consult with your eye care professional and utilize lubricating eye drops. When possible, limit time in air-conditioned, windy, or especially dry environments. Lastly, take regular breaks from digital devices.

Healthy Cardiovascular Health Also Promotes Good Eye Health

 In a new study published by the American Journal of Medicine, investigators found that a healthy lifestyle – typically associated with cardiovascular health benefits – also lowered ocular diseases, particularly diabetic retinopathy. The conclusions suggest that attempts to prevent cardiovascular diseases might potentially counteract ocular ones as well.

Nearly 2.2 billion people worldwide suffer from ocular diseases. The consequences of these diseases are vision impairment and blindness. About half of these cases are preventable; the leading causes of eye issues include age-related macular degeneration, diabetic retinopathy, cataract, and glaucoma.

"Earlier studies have observed associations between eye diseases and individual lifestyle factors such as smoking, obesity, or hypertension," said lead investigator Duke Appiah, Ph.D., MPH, Department of Public Health, Texas Tech University Health Sciences Center, Lubbock, TX, USA. "It is known that these metrics of ideal cardiovascular health do not work alone and may interact additively to result in diseases. However, prior to our research, no other studies have comprehensively evaluated the association of all of the metrics of ideal cardiovascular health with ocular diseases."

The findings show that practicing a healthy lifestyle and implementing beneficial habits are both factors in achieving cardiovascular strength. Age-related macular degeneration, diabetic retinopathy, cataract, and glaucoma can all be minimized by having an active, healthy lifestyle. Those with optimal cardiovascular health had 97 percent lower odds for diabetic retinopathy than individuals who did not.

"Overall, we believe that primary prevention and early detection approaches of ocular diseases are important, considering that over half of all deaths from ocular diseases and cardiovascular diseases are known to be preventable," commented co-investigators Noah De La Cruz, MPH, and Obadeh Shabaneh, MPH, both from the Department of Public Health, Texas Tech University Health Sciences Center, Lubbock, TX, USA.

Laser Treatment Success in Glaucoma Patients Discovered by Researchers

 

Glaucoma is a condition that causes buildup from fluid and pressure inside the eye. If untreated, it can eventually lead to blindness. Over 70 million people worldwide are diagnosed with glaucoma. Therapies to help remediate pressure include eye drops (which help reduce fluid produced by the eye) or surgery to unblock the eye’s drainage system.

Thanks to a study conducted by the University of Missouri School of Medicine and MU Health Care, a non-invasive treatment called Selective Laser Trabeculoplasty (SLT) might provide glaucoma relief. This process uses a laser to modify eye tissue and release fluid, which allows drainage to occur.

The MSM and MUHC research teams reviewed 252 SLT procedures on 198 patients diagnosed with open-angle glaucoma. Following surgery, 33.6 percent of patients achieved a 20 percent or higher reduction in intraocular pressure (IOP) after two months. At six months, 38.5 percent of patients had diminished IOP. Overall, patients with a higher baseline IOP had considerable reductions in pressure.

"There's been a lack of evidence about how well SLT works, how safe it is and the ideal candidate," said senior author Jella An, MD, an assistant professor of ophthalmology and a fellowship-trained glaucoma specialist at MU Health Care's Mason Eye Institute. "Because so little is known about SLT, there is a lot of apprehension among specialists about using it as a first-line treatment for glaucoma. Our research findings have helped me redefine the ideal patient for this procedure."

Saints QB Jameis Winston Opts for LASIK Eye Surgery

 NFL Saints Quarterback Jameis Winston is the latest pro athlete to undergo LASIK eye surgery. The QB said he could read license plates and street signs following the surgery. He said, “I think precision in the vision is the biggest difference.” Previously nearsighted in addition to having astigmatism, which is a curvature in the eye or lens, Winston’s vision is now corrected.

 A growing number of professional athletes are choosing to undergo LASIK eye surgery. Some famous athletes include Tiger Woods, Tiki Barber, Dwayne Wade, Carson Wentz, Lindsey Vonn, Kirk Cousins, LeBron James, Wilson Ramos, Greg Maddux, Patrick Ewing, and Chris Paul.

 

Vision is integral to an athlete’s performance. Without strong vision, performance on the athletic field is diminished. Quarterback football players are continually shifting their eyes by calculating depth, distance, and rapidly-moving players. The quick decisions he makes based on his vision capabilities are what could win or cost the game.

 

Glasses or goggles can impair and even be potentially hazardous to athletes due to their susceptibility to damage and inability to protect their eyes during rain or snowstorms. LASIK eye surgery is a perfect option for athletes and other individuals who move quickly or are frequently in the elements.

PRK vs. LASIK Eye Surgery: What’s the Difference?

 

PRK (photorefractive keratectomy) is a type of refractive surgery to correct myopia (nearsightedness), hyperopia (farsightedness), and astigmatism. It was the first surgery developed for vision correction and came before the popular LASIK procedure. PRK works by reshaping the cornea using an excimer laser. It’s similar to LASIK in that they both use lasers during treatment; however, PRK surgery takes slightly longer to recover from. PRK’s are still commonly performed and, in some cases, offer advantages over LASIK eye surgery.  

 

Both LASIK and PRK work by reshaping the cornea using an excimer laser, allowing light to enter the eye to focus on the retina for clear vision. The main difference between PRK and LASIK is the first step of the procedure. During PRK, the thin layer of the cornea (epithelium) is removed before reshaping the underlying corneal tissue with an excimer laser. The epithelium regenerates itself (grows back over the cornea) within a few days after surgery. With LASIK, a thin flap is created on the cornea using a microkeratome or a femtosecond laser. The flap is lifted to expose the underlying corneal tissue and is replaced after the cornea is reshaped with an excimer laser. 

 

LASEK (with an e) is essentially another version of PRK; however, this procedure entails removing the outer layer of the epithelial layer of the cornea. As with PRK, LASEK involves lifting the epithelial layer by using a trephine, a type of surgical instrument. The epithelial layer is preserved during surgery and then placed back on the eye’s surface once the procedure is complete. LASEK has decreased in popularity due to the slower recovery of vision compared with PRK. The epithelial layer that is placed back on the eye takes longer to recover in LASEK than the growth of a new layer as in PRK. 

 

 

After Surgery: 

 

Outcomes of PRK and LASIK are very similar. Many people can achieve 20/20 vision once they have had the procedure, and almost all patients achieve a 20/40 visual acuity or better. After PRK and LASIK surgery, complications are rare but can occur. Complications can include infection and starbursts or halos around lights at night. Reading glasses may also still be required after PRK surgery once you reach your 40s, due to an age-related loss of near vision called presbyopia. 

 

When it comes to corrective vision, LASIK is by far the most popular option for the majority. However, it’s essential to follow the guidance and judgment of your eye surgeon regarding whether PRK or LASIK is the best option for your individual needs. 

Thin Cornea Treatment Options

The human eye is an amazing organ comprised of fifteen parts, all working together so we can experience vision. Over time, our eyes start to age showing signs of lost efficiency of various functionalities. One of the main parts of the eye, the cornea, is a fascinating piece of tissue. It is comprised of five layers, all of which are designed to be optically transparent. 

The cornea provides a surface for the tear film, the layer of moisture with multiple functions, to cling to. Light is bent by the greatest degree when passing through these structures so it can be focused on point with the retina. The crystalline lens accounts for the remaining third of refractive power. 

Refractive issues appear when the power of these anatomical components – the cornea and crystalline lens is not well coordinated with the physical length of the eyeball. In hyperopia (long-sightedness), the eyeball is too short for its refractive power, and in myopia (short-sightedness), it is too long. 

Common surgeries such as LASIK and PRK have addressed this imbalance of refractive power to eyeball length by reshaping the cornea. Thin corneas can be treated with refractive procedures, and treatment suitability is also subject to other eligibility criteria such as pre-existing corneal disease and even lifestyle factors. Therefore, it is important to choose the appropriate candidates for each type of procedure.

The minimum corneal thickness required for refractive surgery is dependent on the degree of refractive error that needs to be corrected. The higher the refractive error, the higher the prescription required, and usually, the more tissue that needs to be removed. 

LASIK procedures require the creation of a flap of corneal tissue and, for those with thin corneas, make it challenging for reshaping. PRK surgery solves this issue by removing the very top layer, known as the epithelium, which leaves the rest of the corneal matter available for sculpting by laser. However, there are still requirements for patients considering PRK surgery, and sometimes other options must be considered that do not involve a laser to reshape the cornea. 

Some options include intraocular contact lenses, or implantable contact lenses (ICL). These lenses are artificial and are made of biosynthetic material that goes between the iris and the crystalline lens. However, not everyone may benefit from these lenses, and LASIK or PRK treatments may be more suitable to those who could benefit from a more permanent solution.
