Diseases of the Optic and Retinal Nerve

There are numerous diseases and processes that could potentially affect the optic nerve, as well as the retina. These could include ischemic disease or vascular disease, degenerative disease, and infectious or inflammatory disease. Depending upon how damaged the eye becomes during each type of illness will determine the targeting for the prosthesis.

What Damages Could Occur to the Eye?

Following a diagnosis of diseases to the eye, the processes could begin to cause selectively damage to certain areas of the optic or retinal nerve. If there is a need for a prosthetic device to be worn by the patient, the damage caused by the disease could potentially cause design implications for the potential use of this therapeutic visual device.

What Are the Types of Diseases of the Outer Retinal Nerve?

There are conditions that are specific to the outer retinal nerve and they include pathologic myopia, age-related macular degeneration, and retinitis pigmentosa. Despite the fact that there is the potential for the retinal photoreceptors becoming lost, patients can rest assured that their inner retina is still preserved relatively well with regards to these diseases. Therefore, they could still be targets for retinal prosthetic devices.

What Are the Types of Diseases of the Inner Retinal Nerve?

There are diseases that are specific to the inner retinal nerve, and they include such vascular diseases such as retinal venous occlusive disease, diabetic retinopathy, and retinopathy of prematurity. Other retinal layers could become affected by other retinal diseases such as ocular infections (retinitis, endophthalmitis). Prosthetic devices created for the stimulation of the inner retina might not be effective due to the destruction of the inner retinal cells, including of the retinal ganglion cells, during these diseases.

What Are the Most Common Diseases?

There are some eye diseases that are more frequent than others. Some of the most common diseases with regards to the optic nerve are glaucoma, ischemic optic neuropathy, and optic neuritis. When these diseases occur, the ganglion nerve cells themselves become damaged. This means that, for these diseases, the prosthetics will need to emphasize the visual cortex or another targeted area of the visual pathway.

Final Thoughts:

When choosing a visual prosthetic device, it is clear how crucial it is to have a sound understanding of optic and retinal nerve disease pathophysiology. This is particularly true with regards not only to the selection of the prosthetics, but to the design of the optimal visual device as well.

Adult Vision: Over 60 Years of Age

Even though our vision changes as we age, that doesn’t mean this has to be a reason why our lifestyles has to change. When we know what to expect ahead of time and when to seek help from professionals, we can better safeguard our vision.

Upon aging to your 60’s or older, it’s imperative to contentious of age-related warning signs related to eye health problems that could result to vision loss. Some eye diseases do not have early symptoms. The condition could be advanced before you become aware of a condition because it may develop painlessly. Lifestyle choices that are wise, as well as eye exams that occur regularly improve chances significantly for maintenance of optimal eye health while aging.

People Over 60 & Adult Vision

When your vision is protected, the quality of your life is tremendously impacted as you age.

It may not be obvious to you how much the rest of your body’s health can also effect the health of your eyes also. Those with hypertension or diabetes, or taking prescription medication with side effects that are eye-related, have the greatest risk of vision problem development.

That being said, as you reach your senior years, having regular eye exams is increasingly more important. According to the American Optometric Association, individuals over the age of 60 should have eye exams annually.

Vision and Eye Problems Related to Age

During the years following age 60, many eye diseases could occur causing permanent vision changes. It is possible to retain optimal vision if these issues are detected and treated early.

Here are some vision disorders you be aware of as you age:

AMD (age-related macular degeneration), a disease of the eye that affects the macular, causing central vision loss. Despite being small, the macula’s purpose is being part of the retina allowing for sight of finer colors and details. Activities like driving, facial recognition, reading, and watching TV all require good macular vision. Side and peripheral vision remains unaffected by macular degeneration.

Eye Exams for Seniors

Devastating diseases like macular degeneration and glaucoma can be caught by having annual eye exams early. Healthy vision during senor years is maintained and increased through early detection.

People who have diabetes could have a condition called diabetic retinopathy. This occurs when tiny blood vessels responsible for nourishing the retina progressively become damaged. Vision becomes clouded when these vessels lead blood, as well as other fluids. This condition typically affects the patient in both eyes. When a patient has diabetes for a prolonged period of time, they are more likely to develop this condition, which could ultimately lead to blindness.

The separation or tearing of the retina is referred to retinal detachment. When trauma occurs to the head or the eye, eye inflammatory disorders exist, or advanced diabetes exists this could be the result. However, it is a spontaneous occurrence when the gel-like fluid filling the back of the eye changes. Permanent vision loss could be the result if not treated promptly.

Causes, Diagnosis, Symptoms & Treatment for Eye Pain

At some point, nearly all people has experienced sore eyes or eye pain. Sometimes these symptoms relieve themselves on their own, however they could be a sign of something more problematic. 

A diagnosis and treatment can be determined by your eye doctor.

The Causes for Eye Pain:

Pain or discomfort could be caused from eye problems or its surrounding structures, such as:

  • Conjunctiva: the covering that is ultra-thin on the eyelid’s inside.
  • Cornea: the front window of the eye used to focus light coming in.
  • Eyelids: continuously offers protections and moisture to the eye.
  • Extraocular muscles: eyes use these muscle to rotate.
  • Iris: the eye’s colored area.
  • Nerves: visual information is carried to the brain from the eyes.
  • Orbit: the cave that is bony where the eye muscles and eyes are located.
  • Sclera: the white of the eyes.

Problems of the Eye:

Blepharitis: and infection or eyelid inflammation causing pain or irritation.

Conjunctivitis (otherwise referred to as pinkeye): viral or bacterial inflammation of the conjunctiva. Could also cause discharge and itchiness.

Corneal abrasions: an abrasion on the cornea caused by a scratch that can be extremely painful.

Corneal infections: infected or inflamed cornea sometimes the result of shingles, wearing contacts that are not properly disinfected or cleaned, or wearing lenses overnight.

Foreign bodies: an irritant in the eye that, if not removed, could cause an abrasion.

Glaucoma: this condition typically has no symptoms early on. However, acute angle closure glaucoma does and it’s in the form of sudden internal eye pressure. To prevent blindness, treat immediately as an emergency situation.

Iritis or uveitis: an uncommon condition whereby the inside of the eye becomes inflamed.

Optic neuritis: inflammation occurs from the nerve leading from the eyeball’s back nerve to the brain.

Sinusitis: the sinus cavities experience an infection leading to pressure behind eyes.

Stye: localized infection on the eyelid due to inflammation or infection due to oil glands or eyelash hair.

Eye Pain: The Symptoms

Pain of the eye can occur solely or in addition to multiple symptoms, including:

  • Crusted eyes after sleep
  • Discharge, can be clear, colored or thick
  • Headache
  • Pinkeye or red eye
  • Sensation of foreign bodies
  • Sensitivity to light
  • Tearing
  • Vision decrease
  • Vomiting or nausea

Diagnosing Eye Pain

If you have eye pain, see your eye doctor; particularly if you have headache, loss of vision, vomiting, or nausea.

There are a variety of tools used by eye care specialists for diagnosing eye pain, including:

  • Structures of the eye are viewed with a slit-lamp.
  • To see deep into the eye, dilating drops are used.
  • To detect glaucoma, a pressure gauging instrument is used.

Treatments for Eye Pain

Treatments for eye pain vary just as much as their causes:

Conjunctivitis: eye drops that are antibacterial, as well as antihistamines.

Corneal abrasions: ointments.

Glaucoma: pills or surgery.

Cornea infections: eye drops.

Iritis: eye drops.

Optic neuritis: corticosteroids.

Styes: warm compresses.

The best way to determine the causes for and determine the right treatment for eye pain is to see your eye doctor. Your vision should be treated as though it is precious, therefore all pain of the eye should be taken seriously.

Good Supplements for Eyes

Eye supplements simply refer to the nutritional products, which consist of vitamins, minerals, and other nutrients that are scientifically proven to be beneficial for the health of the eyes. These products are created in such a way that they will add to the nutrients that you already obtain from your diet.

With the advancements in the field of medicine, researchers were able to discover which vitamins and minerals are actually useful in preventing eye problems. If you are looking for good supplements for your eyes, make sure that the product that you will purchase contains all or most of these essential nutrients:

Vitamin A

According to research, Vitamin A can improve vision at night, healing of wounds, as well as the overall functioning of the body’s immune system. The retinas of the eyes need this vitamin in order to function properly and produce rhodopsin.

B Vitamins

Choline, folic acid, biotin, and  vitamins B1, B2, B3, B5, B6, and B12 are collectively called vitamin B complex. This group of vitamins are important for the reduction of inflammation and regulation of homocysteine levels that can affect the retinas. These vitamins are also used to treat uveitis and prevent macular degeneration.

Vitamin C

This vitamin is considered as a great antioxidant and is beneficial for the prevention of cataracts, increased eye pressure, and macular degeneration.

Vitamin D

According to research, vitamin D can reduce the risk of macular degeneration.

Vitamin E

Just like vitamin D, this vitamin can also prevent macular degeneration. Moreover, it can also reduce your risk of cataracts and even protect your body from harmful free radicals.

Copper

Low levels of hemoglobin in the blood can result in loss of vision. One of the most essential elements that can maintain your hemoglobin and blood circulation is copper.

Zinc

This mineral plays a key role in converting beta-carotene into vitamin A, which is good for the eyes. Furthermore, the eyes are the part of the body which have the highest amount of zinc and need this mineral for proper functioning.

Chromium

Studies have shown that those who have low levels of chromium in their body have a higher risk of developing intraocular eye pressure. With this, taking eye supplements with chromium can help regulate intraocular eye pressure.

Selenium

This mineral can fight infections and free radicals that may damage the lens and macula of the eyes.

Lutein

Lutein is found in the retina and can protect the eyes. Having high levels of lutein can reduce the risk of age-related macular degeneration and cataracts.

Bioflavonoids

Bioflavonoids can aid in the absorption of vitamin C and production of rhodopsin, which is a pigment that is essential for good vision.

 N-Acetyl Cysteine (NAC)

NAC refers to an amino acid that can lessen the risk of vision loss.

Phytochemicals

Phytochemicals found in bilberry, ginkgo biloba, and other plant extracts can protect the eyes against oxidative stress.

Quercetine

This flavonoid has useful anti-inflammatory, antihistamine, and antioxidant properties. Quercetin can help in the prevention of bruising, protection of capillaries, and lessening the risk of cataracts.

Glutathione

This amino acid can prevent different eye problems such as cataracts, retinal diseases, glaucoma, and blindness due to diabetes.

Omega 3

Omega 3 fatty acids have numerous benefits, but they play a major role in preventing dry eyes. 

Alpha-lipoic Acid

Just like other antioxidants, Alpha-lipoic acid can protect the eyes from the harmful effects of free radicals.

Rutin

According to scientific research, rutin can be used for the treatment of retinopathy and for the strengthening of the capillaries.

All these vitamins, minerals, and nutrients can be found in natural foods. However, a healthy diet may not be enough for you to obtain the required amount each day. In order to fill in these nutritional gaps, it is advisable to take eye supplements every day. With all the benefits that these products can bring, you will definitely realize that they are indeed a great investment for your health.

Hearts – Hope – Healing

Dr. Lauren Richard Rosecan is a Board Certified Retina Specialist specializing in disease of the retina such as

macular degeneration, diabetic retinopathy, retinal vein occlusions and retinal detachment. He has been in Palm Beach county for over 25 years and has three offices located in  Palm Beach County in the cities of Palm Beach Gardens, West Palm Beach and Boca Raton. He also has one office located in Martin County in the city of Stuart.

He chose to have different locations so he could make it easier for his patients to receive the necessary care.

Many of the local health care centers have approached Dr. Rosecan to see their patients. So many of these patients cannot afford to have health insurance and Dr. Rosecan treats them for free. Many of the patients that he sees are poorly controlled diabetics with severe diabetic retinopathy. There is never a time when

Dr. Rosecan will not treat the uninsured patient. He will perform complicated retina surgery for these patients also at no charge to them. He will fully examine the patient and do the necessary diagnostics to determine the type of treatment the patient needs. So many of the patients need extensive pan retinal photocoagulation

(laser treatment) to treat severe diabetic retinopathy and macular laser to treat diabetic macular edema.

“As the aging and diabetic population grows in Palm Beach County,” said Dr. Rosecan “ so will the need for subspecialists trained in the precise diagnostics and treatments of these eye conditions. Helping people see better and preventing blindness is my greatest reward.”

Dr. Lauren Rosecan Received the Heros In Medicine Award for Physician Local/National Hero

photo3Heroes are men and women who place the needs of others above self and view personal responsibility from a global perspective. The term Hero is often preceded by the adjective “unsung,” but on this day we will sing!

Palm Beach County Medical Society Services, a non-profit organization, hosting the 10th Annual Heroes in Medicine Awards Ceremony.  These prestigious awards honor individuals and organizations throughout Palm Beach County that use their skills and resources in the field of health care to provide outstanding services for the people of our local, national, and global communities.  In addition to properly recognizing our Heroes in Medicine, this initiative serves to encourage and stimulate future heroes by promoting a commitment to community service.

Proceeds from this event benefit Project Access, providing health care for low income, uninsured residents of Palm Beach County; and the Medical Society’s medical scholarship fund.  The awards was presented at the Heroes in Medicine luncheon at the Kravis Center Cohen Pavilion on Thursday, May 9, 2013.
