About Retinitis Pigmentosa

Retinitis pigmentosa (RP) is a progressive inherited disease of the eye, in which the light-sensitive photoreceptor cells located in the retina degenerate.

Fjallraven Kanken Classic buy ff14 gil It is the leading cause of inherited blindness in the developed world.

The disease, which affects approximately 1.5 million people in the world, has no cure, but thanks to research done at the University of California-Santa Barbara, a new stem cell therapy may soon be available that protects photoreceptor cells from the damaging effects of the gene mutation. new balance femme buy ffxiv Items So far, only a small number of legally blind patients with RP have begun a trial. chaussure timberland homme The trial is the first attempt to use stem cells to prevent the loss of vision from RP. ugg classic Adidas soldes An experimental injection of retinal stem cells is placed in the eye with the hope that the growth factors from these cells will protect the retinal cells and prevent them from dying, thus preserving the patient’s remaining vision.

About Childrens’ Tear Duct Problems

Normally, tears drain through tiny opening in corners of the upper and lower eyelids call “puncta,” then enter the nose through the nasolacrimal duct. new balance soldes Sometimes the nasolacrimal duct or tear duct can become blocked or obstructed making it impossible for the tears to drain normally. nike tn This can cause the eyes to run water or even produce a discharge. baskets new balance pas cher Often, the tears well up on the surface of the eye and overflow onto the eyelashes, eyelids, and down the cheek. nike air max This usually occurs within the first days or weeks of life. Sometimes, the eyelids can become red and swollen, even stuck together with yellowish-green discharge since the normal eyelid bacteria are not properly “flushed” down the obstructed system. Probably the most common cause of a tear duct obstruction in kids is a failure of the membrane at the end of the tear duct opening to open fully at the time of birth. nike air max 2017 pas cher adidas superstar femme Generally we see this happening in some 5-10% of newborn infants where one or both eyes is affected with a tear duct obstruction-BUT some 90% clear without any treatment with the first 12 months after birth.

Treatment of Kids’ Tear Duct Obstruction

As most of the time the obstruction will clear on its own, we don’t always have to treat it. nike femme solde new balance 574 But, if it persists and causes the welling up of tears or the sticking or redness of the eyelids we can suggest a gentle massage as a first step and prescribe antibiotic eye drops if necessary. asics gel lyte Sometimes we will need to do a tear duct probing to clear the blockage and in a some more difficult situations we might need to perform a tear duct dilation with a tiny balloon or even insert some microscopic tubes. bottes ugg pas cher ugg grise We perform these types of treatments as a matter of routine and, as a parent I will make sure to thoroughly explain them and answer all of your questions if they become necessary.

About Huntington’s Disease

We now know that certain eye tests may help serve as “biomarkers” for the progression of Huntington’s Disease as well as help understand whether some of the new medications prescribed might be helping to slow its progress. nike pas cher adidas yeezy Huntington’s Disease is an inherited disease that causes the progressive breakdown and degeneration of nerve cells in the brain. ugg australia bailey button adidas stan smith Pas Cher Huntington’s disease has a broad impact on a person’s functional abilities and usually results in movement, thinking and psychiatric disorders. new balance 2017 Most people with Huntington’s Disease develop signs and symptoms in their 30s or 40s, but the onset of disease may be earlier or later in life. ugg noir soldes timberland Medications are available to help manage the symptoms of Huntington’s Disease, but treatments can’t prevent the physical, mental and behavioral decline associated with the condition.

Eye Problems with Huntington’s Disease

One of the earliest and most recognizable eye problems of Huntington’s Disease is a change in eye movements or “saccades” where there is a lag initiating an eye movement to look at something and/or an involuntary reflex saccadic movement that the person can’t control. adidas nmd nike flyknit This loss of eye movement control is quite common. Recent research using Optical Coherence Tomography (OCT) testing that we do right in our offices allows us to study the health of the retinal nerve fiber layer and the health of the nerve fibers around the center of vision, called the macula. What we know is the thinning of the nerve fiber layer on OCT, along with a loss of the macular volume is an indicator of the progression of the disease and can serve to monitor that progression.

About Multiple Sclerosis

Multiple sclerosis (MS) is a debilitating neurological disease that can cause patients to experience decreased vision due to optic neuritis, an inflammation of the optic nerve, as well as diplopia or double vision. nike air max bw We believe that MS occurs because there is an abnormal response of the body’s immune system whereby it is directed against the central nervous system (CNS), ugg boot outlet which is made up of the brain, spinal cord and optic nerves. basket new balance Within the CNS, the immune system attacks myelin-the fatty substance that surrounds and insulates the nerve fibers as well as the nerve fibers themselves. Mochilas Kanken Classic When any part of the myelin sheath or nerve fiber is damaged or destroyed, nerve impulses traveling to and from the brain and spinal cord are distorted or interrupted, producing a wide variety of symptoms.

About Optical Coherence (OCT) Eye Testing for MS

In our office, we routinely use very precise imaging technology called Optical Coherence Tomography (OCT) as part of evaluation, diagnosis and monitoring glaucoma and retina diseases because it allows us to examine the actual nerve fibers of the retina and the optic nerve.

Recent research has taught us that OCT can be used to monitor the degree of atrophy of specific retinal layers-called the “inner plexiform layer” and “ganglion cell layer”-and used as an as an indicator of neuronal tissue damage in patients with multiple sclerosis (MS). timberland soldes For patients with Multiple Sclerosis this is quite valuable as it gives us a non invasive in office test, that in concert with their neurologists, helps us help patients asses the stability of their disease as well as their response to new medications or treatments.

About Angle Closure Glaucoma

Angle Closure Glaucoma is a type of glaucoma caused by a blockage or complete closure of the drainage structure of the eye called the trabecular meshwork. ugg australia asics gel lyte 5 The trabecular meshwork is actually a fine filter, and if it is blocked or obstructed by any alteration in the size or shape of the surrounding structures, or by change in the size or shape of the tissue itself, it will cause the intraocular pressure (IOP) to elevate. ugg australia classic new balance pas cher In instances where the meshwork becomes blocked abruptly, it will cause a sudden rise in the intraocular pressure (IOP), resulting in Acute Angle Closure Glaucoma. adidas homme ugg pas cher Acute Angle Closure Glaucoma is characterized by this sudden rise in pressure which will cause pain, redness, light sensitivity, colored haloes around lights, nausea or vomiting, and blurred vision, and if left untreated permanent loss of vision.

Medications Can Cause Angle Closure Glaucoma

In patients who may already be at risk for Angle Closure Glaucoma because they have certain tissue and anatomical features inside their eyes, certain medications can significantly increase their risk. Two medications that are worth mentioning are the antidepressants Wellbutrin (Buproprion) and Topamax® (Topiramate). UGG Bottes While both of these are often used to treat mild to moderate depression, they are also used to help patients stop smoking!
