Aphantasia Could Be Diagnosed Based on Pupil Size

Pupil size fluctuates to let just the right amount of light into the eye. Vision is improved by contracting the brightness and dilating in the dark. New research shows that beyond light changes, pupil size might also change based on perceptual and cognitive circumstances. 

Mental imagery was shown to facilitate pupillary responses to light in this study published in the Association for Psychological Science (APS). 

Another study, published in the Journal of Vision (JoV), suggests the pupil constricts in response to a high-light luminance object in a photo, such as the sun. 

A condition known as aphantasia is diagnosed as the inability to produce mental images in the mind. Aphantasia can stem from birth or manifest later in life, despite being otherwise healthy. Researchers studied pupillary responses of people who experience aphantasia to better understand how the brain’s visual and ocular reflexes work.

The study, published in eLife, compared the pupillary responses of people with and without aphantasia. 

Professor Julia Simner leads the MULTISENSE lab at the University of Sussex and was not involved in the study. After analyzing the data, she said, “The fascinating finding reported here is that people imagining light or dark objects show the same type of pupillary action as we would normally find when the eyes are exposed to light and dark objects in the real world. This suggests that their imagination is treated [as] a simulation of the real world. [Meanwhile,] people with aphantasia — who imagine in a more abstract way because they cannot build a picture in their mind’s eye — don’t show the same effect.”

The study participants were asked to imagine 32 white or gray shapes while their pupil size was measured. Other experiments were conducted, as well as a questionnaire. Researchers concluded that people without aphantasia reacted to perceived and imagined luminous images, which affected their pupillary size. Those with aphantasia did not note a change in pupillary size when perceiving or imagining luminous images.

How to Minimize Anxiety Before a Lasik Procedure

Fear and anxiety commonly surround Lasik procedures, and most of the time, it’s purely based on the unknown. One of the most beneficial tactics to combat nervousness about surgery is to inform yourself thoroughly about the procedures.  

Lasik is a quick and painless procedure that generally takes around 15 minutes, and the laser usually touches the eye’s surface for only a few seconds. Most patients are worried about sneezing or coughing, causing injury or bad results. 

Fortunately, complications from Lasik surgery are extremely rare. Also, there are procedures in place that help prevent sudden movements during the process. An intricate laser system monitors even the slightest eye movement and adjusts the laser accordingly, with pinpoint accuracy.

Lasik has a growing track record, as it’s been used successfully for more than two decades. Lasik has the highest success rate of any elective procedure, with a 96 percent satisfaction rate reported in 2016. 

Specialists are trained to support patients through the entire process from start to finish. Laser eye surgeons will supply the patient with information on what to do the day before, the day of, and after the procedure. By being wholly informed and knowing what to expect, patients will undoubtedly feel more at ease about the procedure. 

Deep breathing exercises are always recommended for patients who experience anxiety or stress. It’s imperative to practice the technique a few days prior to surgery. Slow and steady breathing is key. 

Friends or family members can also accompany the patient to provide emotional support and help them through post-surgery. These guests can provide comfort for the patient to keep the mind occupied or remain calm before the procedure. 

Anesthetic drops will numb the eyes, and the physician can provide low doses of anti-anxiety medication if necessary. Overall, Lasik is a painless procedure; most clients report more than slight pressure if anything at all. 

Life without contacts or glasses is possible. Lasik surgery is easier than you think. Contact the experts at Rohr Eye & Laser Center today to learn more.

LASIK Implantable Lens Alternative on the Horizon

After years of seeking FDA approval for its implanted vision-correcting lens, Staar Surgical has successfully reached a regulatory milestone. The Evo/Evo+ Visian implanted collamer lens is designed to treat myopia (nearsightedness) with or without astigmatism and is an alternative to other vision correction options such as glasses or contacts.

Staar first applied for FDA review in 2019 but was given a denial early that year. In August 2019, the FDA approved a clinical study of the lens. Premarket has been approved, and the device has already been implanted in more than one million patients in more than 75 countries outside of the United States. 

Roughly one-third of the United States population (100 million people) between the ages of 21 and 45 who have myopia over -3.0D could be eligible to receive the device.

The Evo device is implanted between the iris and the crystalline lens in the posterior eye chamber, making it a swift procedure that does not require a preoperative peripheral iridotomy, where a laser is used to create a hole in the iris. 

Unlike LASIK surgery, Evo/Evo+ does not require the removal of corneal tissue and is removable by a doctor if necessary. Since myopia is becoming more common, the newly FDA-approved solution to vision loss is necessary. Forecasts imply almost half of the world’s population could be nearsighted by 2050.

Staar has been in the ophthalmic surgery field for more than 30 years, as they design, develop, manufacture, and market implantable lenses for the eye.

Nearsightedness Q&A

Nearsightedness (also called myopia) is common in people of all ages. It is typically defined as an inability to see far away or long distances. Millions of people worldwide suffer from myopia, a relatively prevalent condition. Read on to explore popular questions – and answers – about nearsightedness.

Q: What is nearsightedness?
A: Technically speaking, myopia is a refractive error that results in the eye’s inability to focus on light correctly. While distant objects are blurry, those nearby are visibly clear and crisp. In those who do not have myopia, light rays enter the eye and pass through the cornea and lens, followed by the retina at the back of the eye. When the eyeball grows too long (or the cornea is uneven), light rays focus in front of the retina instead of centered on it, and the image sent to the brain is blurry. Those with nearsightedness can correct their vision by donning prescription eyeglasses, contact lenses, or laser vision correction such as LASIK.

Q: How common is nearsightedness?
A: In a recent study published by Jama, an estimated 30 to 40 percent of adults in the United States are nearsighted. It is estimated that by 2050, nearly half of the world’s population will suffer from myopia.

Q: What causes nearsightedness?
A: The exact cause of myopia is unknown, but contributing factors are well-known and include genetics, eyestrain (books, computers, tablets), and lifestyle (not being outdoors where light is much brighter.)

Q: Is laser vision correction for nearsightedness permanent?
A: While laser vision correction reshapes the cornea and corrects nearsightedness at that exact moment in time, the possibility for the patient’s vision to deteriorate in the future is still plausible. If the patient develops cataracts, glaucoma, or presbyopia (natural aging of the eye), glasses will probably still be necessary when the lens loses its ability to focus on nearby objects.

Q: What demographics are good candidates for laser vision correction?
A: Typically, adults over the age of 20 who have a stable prescription, healthy corneas, and are in good general health are recommended for LASIK or other vision correction procedures.

Sleep Apnea Affects More Than Your Mood

According to the National Sleep Foundation, more than 18 million Americans suffer from sleep apnea. Sleep apnea causes many people to stop breathing while sleeping, often multiple times per night. Those who suffer from this condition generally have ocular irritation, risk of floppy eyelids, dry tear ducts, and an increased risk of developing glaucoma.

There are different types of sleep apnea, the most common being Obstructive Sleep Apnea (OSA), which causes the airways to be partially blocked because of relaxed muscles in the nose and throat. Apnea (the absence of breathing) or hypopnea (slow, shallow breathing) is twice as common in men. It also generally affects people with obesity, hypertension, diabetes, and/or heart disease.

When the muscles in the back of your throat relax too much to allow regular breathing, sleep apnea occurs, causing lower-quality sleep. The body’s oxygen supply is also greatly affected, which can typically lead to serious health conditions. Contrary to the popular misconception, not all those who snore suffer from sleep apnea.

Interrupted sleep can cause a variety of issues such as fatigue, daytime tiredness, irritability, depression, headaches, difficulty concentrating, distractedness, or sore throats.

When it comes to the eyes, sleep apnea can cause several major issues:

  • Glaucoma: increased pressure within the eye can damage the optic nerve, leading to vision loss or blindness.
  • Floppy Eyelid Syndrome (FES): marked by an unusually large and floppy upper eyelid, FES can cause eye redness, irritation, discharge, and blurry vision.
  • Non-Arteritic Anterior Ischemic Optic Neuropathy (NAION): symptoms occur when there is significant vision loss in one or both eyes without any pain, caused by a loss of blood flow to the optic nerve.
  • Retinal Vein Occlusion (RVO): also called an eye stroke, it is categorized by a blockage within the small veins that carry blood away from the retina.

Other eye conditions correlated to sleep apnea include papilledema, keratoconus, and central serous chorioretinopathy.

Getting regular eye exams can prevent vision issues; contact Dr. Rohr’s office to schedule an appointment.

Can Cataract Surgery Protect Against Dementia?

This article might make your decision more straightforward if you question getting cataract surgery. Not only can the correction of cataracts improve your quality of life, but new studies suggest cataract surgery may help protect you against dementia.

A study published in Jama Internal Medicine found that developing dementia was 29% lower for individuals who’ve had cataract surgery versus people with similar traits who didn’t have the surgery. While this information sounds remarkable, it’s important to note that more research is required to say definitively whether or not cataract surgery helps with dementia.

Other studies have taken a look at why cataract surgery may help with dementia. One study explores the idea that impaired vision caused by cataracts can lead to reduced sensory input to the brain. Reduced input means reduced simulation, leading to a loss of brain function. Additionally, a vision loss due to cataracts could lead you into a depressive state. Depression could increase the chance of developing dementia.

We do not know enough about the link between cataract surgery and dementia, and future studies will continue. However, there are some other exciting factors and benefits to consider in the meantime. For example, did you know that cataract surgery has also been thought to help with depression, encourage a longer life span, and reduce the risk of falling?

If you’re struggling with vision, don’t wait until it worsens. Talk to a doctor or medical professional about the benefits of cataract surgery today.

How Safe is LASIK Eye Surgery?

Over ten million Americans have had LASIK eye surgery since its FDA approval in 1999. With 96% of patients achieving their ideal vision through LASIK, it’s no surprise that the procedure has started gaining even more traction. Unfortunately, our increased screen time puts extra strain on the muscles that allow our eyes to focus, a side effect of the digital age.

There’s always a slight risk of complications, including LASIK, as with all surgeries. However, the incident rate is less than 1%. The FDA’s maximum complication rate for approval is 5% which positions LASIK as one of the safest elective surgeries available.

Working with a board-certified surgeon for LASIK procedures is the key to a successful surgery. They’ll be able to answer questions you may have about the procedure, possible side effects, and if any pre-existing conditions could interfere.

Once the surgery is complete, you’ll be given a custom aftercare routine to follow to achieve maximum benefits and promote a quick recovery. LASIK’s common temporary side effects include dry eyes, double vision, glares, and halos from solid light.

These side effects will resolve in 3 to 12 months, with the severity lessening along the way. Their impact is similar to the glare on regular glasses when driving under street lights.

LASIK’s long-term complications make up less than 1% of patients who weren’t satisfied with the outcome. In these cases, patients typically reported an over or under correction of their vision, requiring an additional visit to correct. More corneal tissue will be removed for under corrections, or enhancements can be used to fix overcorrections.

United States Military Tests Wavefront-Guided PRK

With more than 30,000 to 40,000 members of the United States military choosing laser vision correction procedures to improve their vision each year, there is an emphasis on clinical research to examine the efficacy and safety of various procedures available.

A somewhat novel laser vision correction technique, called wavefront-guided PRK (Photorefractive Keratectomy), was recently studied by the United States Navy.

Wavefront-guided PRK implements the newest computer-generated mapping technology to generate a digital image of the patient’s eye. Once the eye is mapped out, the laser applied to the cornea’s surface is guided by the three-dimensional model to improve the eye’s focus based on the unique visual characteristics of the patient’s eye. Even the tiniest structure issues affecting eyesight are revealed through Wavefront-Guided PRK.

The development of wavefront vision mapping allows visual disorders to be measured, which otherwise could not be identified in the past. Laser diagnostic systems are setting a new standard by providing an exact level of measurement and correction. This feat was impossible with earlier systems.

Led by the U.S. Naval Medical Center, 167 patients enrolled had vision prescriptions of up to -8D of nearsightedness and up to -4D of astigmatism. The patients underwent wavefront-guided PRK. Research findings showed:

  • Patient satisfaction was very high, with 98.8 percent reporting entirely or very satisfied with their vision
  • 99.4 percent of patients tested at 20/20 or better vision six months following the procedures
  • 91.9 percent of patients tested 20/16 vision six months after the procedure
  • Fewer than four percent of patients reported night vision symptoms six months post-op
  • Less than one percent experienced adverse reactions

This novel research shows a massive body of evidence supporting laser vision correction procedures proving safety and effectiveness.

Retinal Transplants Ready for Human Trial

A major cause of hereditary human blindness, Retinitis Pigmentosa (RP), has been resolved in rat trials by researchers at the RIKEN Center for Biosystems Dynamics Research (BDR) in Japan. Degenerated rat retinas received transplants and removal of grafted cells, which resulted in improved connections to host retinas and better light-responsiveness.

Study leader Michiko Mandai said, “We have previously reported work using mouse embryonic- and induced pluripotent stem cell – (iPES)-derived retinas in a mouse model of retinal degeneration.”

However, the deputy project leader in the Laboratory for Retinal Regeneration at RIKEN BDR said, “As far as we know, this is the first report of the timed removal of particular grafted cells being shown to improve retinal function in an animal model using tissue from human stem cells.”

Since the retinal sheets were created from human stem cells, the novel feat can now be tested in human clinical trials, according to the study authors in the January 21, 2022 edition of iScience.

“Since retinal ganglion cells form optic nerves to send the signal to the brain, a higher light responsiveness could theoretically lead to improved sensitivity to light or better resolution in visual function. Genetic modification in human stem cell-derived retinas showed a substantial functional improvement [in light responsiveness], compared with wild-type graft retinas. Depending on the retinal network of the transplanted area, light responsiveness of retinal ganglion cells may be correlated with increased signaling to the brain, so could lead to an increased light sensitivity or better resolution. Additionally, we were able to observe detailed host-graft synapse formation in the absence of graft bipolar cells, which previously was difficult. A frequently asked question in retinal cell therapies concerns whether retinal ganglion cell responses are really originated from the graft photoreceptors. The presence of multiple synaptic markers at the host-graft cell contact site suggests formation of some synapses between these cells and indicates that graft photoreceptor light responses may well be transmitted to host retinal cells. We can now move forward to applying this strategy in clinical studies, which we expect to improve clinical outcomes and be generally useful in stem cell-based therapies targeting retinal degeneration. If the clinical grade ISL1-deleted stem cell-derived retinas can first pass extensive safety testing, including for tumorgenicity, we estimate that this may take 4-5 years. While we are currently targeting end-stage disease eyes with stem cell based therapy, we think this strategy could also be applied to those with remaining central vision, to help increase the pericentral visual field or delay disease progression,” Mandai said.
