Patient Advice: What to Expect During a Retinal Examination

Posted on Oct 31, 2014 by

Vision exams are performed to determine the overall health of your eyes and to assess how well you can see. And as we age, they examinations are essential.

 

 

While the exact procedures vary by provider, your doctor may examine your eyes with special lights and perform an eye pressure test. Or, they might have you read from a chart on the wall to determine if you need corrective lenses. Your doctor may even place a unit in front of your face that will help determine your new prescription, if needed.

 

Retinal examinations are performed so doctors can see the back of your eye. This exam is performed so a doctor can see if you’re developing retinal disease or other serious problems that can affect your vision. During follow up exams, your doctor may compare your new results with past ones to detect any changes and begin treatment if necessary.

 

There are two methods for examining the retina. One way is to dilate the eyes with eye drops that keep your pupil open even when the doctor shines a bright light into your eye. This way, your doctor can see the back of your eye where …

This Halloween, Beware of Costume Contact Lenses

Posted on Oct 27, 2014 by

Halloween is just around the corner, and dressing up is all part of the fun for both children and adults alike. In the spirit of dressing up, many adults opt for cosmetic contact lenses that are designed to create certain effects, such as red eyes, zombie eyes, checkered pupils and more. While these contacts can create a great visual impact, they may also cause vision impairment or even blindness.

 

 

Non-prescription lenses may not always be sterile and can cause serious infection. In fact, there were so many problems caused by theses lenses that the Food and Drug Administration (FDA) banned the sale of them by anyone but licensed eye care professionals in 2005. Despite the ruling however, these contacts are still available online, in convenience stores, as well as novelty shops.

 

To reinforce the vision impairment cosmetic contacts can cause, we’ve provided some reasons you should reconsider purchasing and wearing these lenses.

 

**Poor Fit – Since cosmetic contacts are not properly fitted to your eyes, they can cause corneal scratches, pain, light sensitivity and more. **Corneal Ulcers – Often appearing as white spots on the colored portion of the eye, these ulcers have similar symptoms to scratches, but they can form scarring that permanently …

Optos is teaming up with the Academic Sector to Fight Blindness

Posted on Oct 24, 2014 by

As reported in the Courier, Optos has announced a commitment of up to £10 million in conjunction with NHS Greater Glasgow and Clyde and the academic teams at Strathclyde and Kent University to develop retinal imaging technology that will provide earlier detection of diseases and conditions that cause sight loss.

 

 

The initial stage will begin with a £1.1 million study funded by Optos and Innovate UK, formerly known as United Kingdom Technology Board. The study will focus on improving laser technology to track cell function and provide earlier detection of disease formation, so eye diseases can be treated in its earliest stages. With anticipated completion by the beginning of 2017, the earliest studies will focus on AMD, diabetic retinopathy and glaucoma.

 

If these studies are successful, Optos will commit £9 million pounds to develop fully licensed retinal imaging technology by 2018. “We are delighted to play a key role in this collaboration with the NHS supported by clinical research,” said chief executive of Optos Roy Davis.

 

The intent of the entire project is not only to prevent blindness, but to prove that collaboration with the academic sector and other entities can provide new technology for enhancing patient outcomes.

Patient Advice: Staying Safe for Eye Injury Prevention Month

Posted on Oct 22, 2014 by

Eye Injury Prevention Month is a great time to remind patients how important it is to protect their eye health, not only at work, but also at home or play. While various types of injuries to the eyes occur in roughly 2,000 cases per day, nearly half of that number is caused by injuries while at home or in the yard. Many of the remaining cases can be attributed to injuries while at work.

 

 

Despite the high number of eye injuries reported, it’s estimated that more than 90 percent of eye injuries can be prevented with the use of protective eye wear. Unfortunately, more than 78 percent of those injured were either not wearing eye protection, or they were wearing inadequate protection for the task they were performing.

 

In order to protect your eye health and maintain healthy vision throughout your life, it’s essential to wear protective eye wear when performing certain tasks. Here are some tips to get you started:

 

**Always wear the recommended eye protection when at work. If face shields are required, don’t rely on wearing safety glasses. **Make sure to have certified safety glasses and goggles on hand in your home. Most eye injuries happen in the home or …

The Push for Improved Diabetic Retinopathy Screening in Pregnancy

Posted on Oct 20, 2014 by

While diabetic mothers-to-be are apt to visit their medical doctors frequently and carefully monitor their sugar levels, many of them don’t schedule or receive proper retinal screening exams throughout their pregnancies. In fact, in a study of 300 pregnant women with type I or type II diabetes, 40 percent did not receive the recommended two retinal exams during two trimesters of their pregnancies.

 

 

Patients and doctors alike understand that diabetic retinopathy can be a serious condition in pregnant women, so planning and attending a retinal exam during two of the trimesters is a critical process.

 

In the study mentioned above, 26 percent of the women who received adequate screening were found to have worsening diabetic retinopathy, which is a significant reason to reinforce the importance of retinal screening in pregnancy. Women in the study who had a higher systolic blood pressure reading at their initial prenatal checkup and had the lowest HbA1c were the ones most likely to show increased diabetic retinopathy.

 

This stands to reason since diabetes can be significantly harder to control during pregnancy and can also form for non-diabetics. Some participating doctors found that women with normal vision at the beginning of their …

Patient Advice: Protecting Your Eyes This Winter

Posted on Oct 10, 2014 by

Summer may be over, but that doesn’t mean you should put away your sunglasses. Many people don’t realize that winter can be just as, if not more damaging, to their eye health than the hot and sunny days of summer. The following information can help ensure your patients maintain healthy vision all season long.

 

 

Even though winter may seem gloomy, the sun doesn’t go away. Inform your patients that if they’re headed outside this winter, they should wear proper eye protection in order to avoid photokeratitits. This condition is basically sunburn to delicate eye tissue, and it can range from light damage to permanent vision loss.

 

The effect of sun damage can be amplified by the refractory effect of snow, so they should always have proper eye wear with when heading outdoors to ski, shovel snow, or simply commute to work. Over-exposure to the sun’s UVA and UVB rays has also been proven to increase the occurrence of cataracts and age-related macular degeneration.

 

As with all seasonal sports or activities, goggles and safety glasses should be worn. Debris, ice particles, and blow back from snow removal equipment can cause severe damage and even blindness.

Foods That Might Reduce Your Patient’s Risk of Glaucoma

Posted on Oct 06, 2014 by

Caused by increased ocular pressure, glaucoma eventually damages the optic nerve, resulting in low vision or complete blindness. Although there is no cure for glaucoma, more and more research on the benefits of good nutrition is being done.

 

It’s important to note that these nutritional recommendations are not a definitive proof for reducing glaucoma. Since these suggestions offer many other health benefits, there’s no harm in encouraging your patients to improve their diets and try to incorporate the following suggestions whenever possible.

 

Focus on Color

 

Fruits and vegetables high in color, particularly green leafy vegetables and orange fruits and vegetables, are rich in antioxidants and nutrients that contribute to eye health. Any fruits and vegetables, including berries that contain vitamins C, E and A, are also beneficial because of their antioxidant properties. Antioxidants zeaxanthin and lutein are found in high concentrations in the eye.

 

Heart Healthy is Glaucoma Friendly

 

Increased blood pressure can exacerbate the effects of glaucoma, since they’re both related to pressure. Minimizing salt intake and limiting fats can contribute to better eye health. Retinol, which is found in butter, cheese and milk, is a great form of vitamin A that’s also eye-friendly. Patients should consume adequate amounts …
