Ocular hypertension is a condition where the interior pressure of your eye is higher than what is considered normal. While some people who suffer from the affliction show no outward signs and maintain their vision, some people develop glaucoma and risk losing their vision. Knowing and understanding the causes of ocular hypertension may help you preserve your vision.

Causes of Ocular Hypertension

There are several factors that cause high eye pressure or contribute to the condition and they are closely related to the causes of glaucoma. The main cause of ocular hypertension is an imbalance of the clear fluid (aqueous humor) that flows through your pupil to the front chamber of your eye, between the colored portion (iris) of your eye and the cornea. When too much aqueous humor is produced, or the fluid is not able to drain as it should, the result is ocular hypertension. Other factors that may contribute are:

– Steroid medications taken orally or by eye drops may increase your eye pressure. If you have to take steroid medications, speak to your doctor about having your intraocular pressure (IOP) tested. Although steroids are most common to affect eye pressure, ask your physician or …

As we age, chronic conditions and physical changes may threaten our independence. Among these is vision loss or low vision. While at one time vision loss may have threatened independent living, there are many resources for senior independence and vision loss that make it possible to carry out the activities of daily living without requiring care.

According to the American Council for the Blind (ACB), more than seven million people over the age of 65 have experienced serious degrees of vision loss with most due to age-related conditions. As the baby boomer generation heads towards senior ages, this number is likely to double by the year 2030. The most common age-related conditions that are causing the serious vision loss are:

– Glaucoma – Age-related Macular Degeneration -Diabetic Retinopathy -Cataracts

If you have not already experienced significant vision loss, or you have not been to see your eye care provider in some time, regular comprehensive eye exams including optomap® UWF™ digital imaging are critical to maintaining your vision. If you are experiencing vision loss, it is even more important to keep the monitoring schedule set by your doctor.

Senior Independence and Vision Loss

With many resources available, vision loss does …

As the leading cause of blindness in American adults age 65 and older, age-related macular degeneration (AMD) is expected to affect as many as three million people by the year 2020. AMD occurs when the macula, which is responsible for fine detail and central vision, becomes degenerated with age. Dry vs wet AMD are the two forms of the disease and you should know and understand the difference.

Wet AMD

Sometimes causing straight lines to appear wavy in its earliest stages, wet AMD is more advanced than dry and can deteriorate your vision rapidly. Wet AMD is caused by abnormal, fragile blood vessels that grow behind the macula. These vessels are often very fragile and tend to leak blood and fluid, causing the macula to raise and become damaged. All patients who develop wet AMD started with the dry form so it is critical to get regularly scheduled comprehensive eye exams including optomap® to detect the disease in its earliest stages to prevent permanent vision loss.

Dry AMD

The dry version of AMD has three stages which can affect one or both of your eyes. The three stages are defined by the size and number of fatty yellow protein deposits …

History

A 15 year-old African American female with a history of bilateral threshold retinopathy of prematurity was seen for a routine annual visit. As an infant, she was treated with scatter laser photocoagulation two months after her birth. At this visit, she was asymptomatic with a visual acuity of 20/25 in the right eye and 20/15 in the left eye.

Examination

optomap® color images were obtained and showed a reddish orange, slightly elevated lesion at 2 o’clock in the far periphery of the right eye, anterior to the equator. Images also confirmed areas of previous laser treatment in the temporal periphery. optomap fluorescein angiogram images were obtained and showed the lesion to be hyperfluorescent and that the lesion had feeding and draining retinal vessels. The left eye did not have similar lesions, but did have evidence of previous laser treatment in the temporal periphery.

Discussion

optomap color and fluorescein angiography were used to document the appearance and investigate the characteristics of the peripheral lesion. The lesion was determined to be reactive angiomatous proliferation – a rare vascular proliferation which has been reported to occur in various chronic retinal diseases, such as retinitis pigmentosa and …

Prevent Blindness and the American Ophthalmologist Association have jointly named August as Children’s Eye Health and Safety Awareness Month. As you prepare your children for a successful new school year, be sure to schedule a comprehensive eye exam and take this opportunity to teach them about eye safety.

Thousands of children suffer eye injuries each year and 90 percent of these injuries are preventable if protective eye wear is worn when needed. To get the most of children’s eye safety month, review the following helpful guidelines and be sure to speak to your children about them:

– Always ensure there is proper eye safety protection for activities – Be sure the protective eye wear is designed specifically to the activity being performed – Corrective lenses are not a substitute for safety eye wear – Only provide toys that are age-appropriate – Avoid toys with sharp or pointed components – Teach children that projectiles can cause serious eye injury and perhaps blindness

It is estimated that roughly 80 percent of education is delivered visually, which means if your children’s eyesight is not at its best, they may struggle unnecessarily. A comprehensive eye exam including optomap® provides your child’s eye care …

According to the American Cancer Society, there will be an estimated 2,580 eye cancers diagnosed in 2015 with most of them occurring as melanoma of the eye. While this number is not staggering when compared to the overall population, melanoma can be fatal. As with most cancers, Cancer Research UK has published stats indicating that early detection is your best chance at survival if you are diagnosed with ocular melanoma.

What is Melanoma of the Eye?

Melanoma is an aggressive cancer that forms in the cells responsible for skin pigmentation through the production of melanin. Since your eyes also have melanin-producing cells, melanoma tumors can form in various parts of your eye. Although the choroid layer is the likely site for ocular melanoma, the following parts may also be affected:

– Ciliary body – Iris – Conjunctiva – Orbit – Eyelid What Causes Ocular Melanoma?

While an exact cause is not known, the Mayo Clinic describes ocular melanoma as a DNA error that prevents cells from shedding in their typical life cycle. Cells grow uncontrollably and mutated cells accumulate rather than dying off and form melanoma. Despite the notion that it caused by a problem with DNA, there are …

Introduction

Duke University Eye Center has been using their optomap enabled device since September 2006. During that time the image quality, increased field of view and ease of use have added value to the practice. Below details a case study which demonstrates the unique value of ultra-widefield fluorescein angiography offered by Optos in patients with age related macular degeneration.

History

The female patient was diagnosed with dry AMD 1.5 years ago with nuclear sclerotic cataracts in both eyes. At this visit the patient presented with a change in visual acuity in the prior six months. Routine examination revealed an IOP of 15 in the right eye and 18 in the left, with visual acuity at 20/100(rt) and 20/40(lt).

Examination

This case study captured by the Optos ultra-widefield digital imagingdevice demonstrates the benefits offered by the technology. Duke University photographers were able to acquire a clear image set through relatively dense cataracts; something that is always a challenge with traditional mydriatic white-light based cameras. The red/green laser allows for less scatter as the beams enter the anterior segment allowing for a better image of the retinal surface.

The ultra-widefield image illustrates AMD changes affecting both the central and peripheral …

According to an article written by Paul E. Tornambe, MD, FACS and appearing in the April 2015 issue of Retina Today, Optos’ ultra-widefield (UWF™) retinal imaging is helping manage and advance knowledge in diabetic retinopathy (DR). In fact, Tornambe can be quoted as saying UWF retinal imaging “…will facilitate earlier diagnosis, more accurate evaluation and better treatment outcomes.”

How UWF is Improving Diagnosis

Several studies have been conducted and indicate that UWF imaging has the potential to improve diagnosis and management of DR. In the article, Tornambe references several studies that show, compared to standard technology, optomap® provides high resolution images that allow for a much larger view into the periphery of the retina (200 degrees), the images are acquired rapidly and often, the patients’ eyes do not have to be dilated. Not only are the images much higher quality, it stands to reason patients are more likely to maintain a proper diagnostic schedule if they do not have to undergo dilation.

With multiple modalities such as fluorescein angiography and red-free color imaging, Optos UWF technology consistently reveals more pathology if present than other diagnostic tools are able, leading to earlier diagnosis in some cases and more advanced disease progression in others who …

For years the doctors of Kapperman and White, a Vision Source® practice, used dilation as the standard of care for every one of their patients. That is, until they saw the Daytona at the 2013 Vision Source Exchange. “All three of us went from being skeptics to being huge believers. The 200° optomap image shows us so much of the periphery that we may not have otherwise seen.  And it allows us to explain the need for a dilated exam more clearly, too,” says Kr. Kapperman.

The images provide the doctors with the data needed for clinical decision-making and they improve the level of patient education they also improve the level of patient education they can provide with tools such as 3D Wrap, a virtual tour of the eye.

In the first year of having the system between 60-80% of all patients opted for the procedure and according to doctor Kapperman, the screening fee contributes significantly to the practice’s bottom line.
