The Effect Of Myopia On Measuring Peripapillary Retinal Nerve Fiber Layer Thickness

The records have been reviewed. The member is an adult male with a birth date of 05/16/1973. He has a diagnosis of bilateral degenerative myopia. His treating provider, Amy Camarota, OD, recommended treatment options on 03/18/2016, one of which was scleral lenses, which the member opted and paid for on 04/01/2016.

How does the progression of optic nerve and RGC damage translate to the clinical symptoms of glaucoma? In a study published by Harwerth and Quigley in 2006, the structure-function relationships of human glaucoma and experimental glaucoma in monkeys are compared, in order to discern a possible correlation between the progressive loss of visual field experienced by glaucoma patients and the gradual neural losses. Previous studies had suggested a large amount of variance between the well-defined relationship of experimental glaucoma and the slightly different system of clinical glaucoma, but the discrepancies could have equally resulted from different methods of data analysis, which would affect the precision of the results. The study compared

Glaucoma can occur without much warning, whether its acute from a accident in which a trauma is issued on the eye, or if it is due to age and heredity. Glaucoma doesn 't discriminate, it is seen in all races and genders. It happens so slowly with age and heredity that you don 't even notice the loss of vision until it is too late, and with acute glaucoma it can be painful with pain that radiates over the face, a headache, nausea, vomiting and seeing colored halos around lights and even blurred vision can be a few symptoms (Ignatavicius & Workman, 2013). Once you start seeing halos, and lose peripheral vision, it may be an indicator that irreversible damage to the optic nerve has happened. In this paper we will discuss the pathophysiology of glaucoma, the types of glaucoma as well as the causes for them. the issues that glaucoma can cause someone, and the treatments and interventions. We will also have a education handout to help better understand how to administer the medication, and the effects it has on the eye.

Glaucoma is a disease that damages the optic nerve because of extra fluid increasing pressure in the eye (Boyd). It is also the leading cause of blindness if left untreated in people over sixty Boyd states. Varieties of options are available for treatment regarding glaucoma and all are intended to lower the blood pressure and protect optic nerve (Radhakrishan and Iwach). Glaucoma can be treated with eye drops, pills, and surgery or a combination of these methods. (“Treating Glaucoma”). Right now eye drops are the first choice of treatment because they lower eye pressure, helping fluid drain better or decreasing fluid made by the eye (Radhakrishan and Iwach). As is states in the article “Treating Glaucoma” when eye drops cannot control the glaucoma,

Subjects diagnosed with migraines (according to the criteria established) and non-migraine subjects (detailed questionnaire was given to control subjects to rule out any history of migraine) were recruited. Twenty-two patients with migraine and 20 age-matched control subjects were included. All migraine patients and 17 out of 20 control subjects were females. Visual acuity, refraction, and intraocular pressure (IOP) were measured in all subjects followed by an anterior segment slit lamp exam and a dilated fundoscopic exam. Stereo disc photographs and standard automated visual field tests (Humphrey Field Analyzer; Humphrey Instruments, Dublin, CA, USA) were obtained. Subjects with unreliable visual field tests were excluded. The photographic slides were projected onto a screen and the disc and cup diameters were measured horizontally and vertically with a ruler. The horizontal and vertical C/D ratios were calculated by dividing the cup by disc size. Using the Student’s t-test, patient demographics, IOP, visual field parameters, and optic disc parameters were compared. The correlation between visual field and disc parameters was tested by using Spearman’s rank correlation. A p value <0.05 was regarded statistically

The Optomap® Retinal Exam is used to get an ultra-widefield view of the back of the eye. While eye exams generally include a look at the front of the eye to evaluate health and prescription changes, a thorough screening of the retina is critical to verify that your eye is healthy. This can lead to early detection of common diseases, such as glaucoma, diabetes, macular degeneration, and even cancer. The exam is quick, painless, and may not require dilation drops. Dr. Rhodes and Dr. Zemanovich will educate you about the structures of your retina and interactively review and discuss the results of your exam. The optomap® photography provides a permanent record of the condition of your retina, which will allow the doctors to compare each year’s

When you go see your doctor, make sure you ask them to write down your pupillary distance (PD) measurement on your prescription. The PD measures

This article discussed the eye disease, Glaucoma. There are two types of Glaucoma; open-angle and closed-angle. Open-angle Glaucoma there are no visual abnormalities, but there is a mechanical obstruction interfering with the drainage pathway. While closed-angle Glaucoma is a physical obstruction. Signs and symptoms of Glaucoma are; headache, nausea, vomiting, blurred vision, halo vision, and eye pain. Glaucoma progresses slowly and is asymptomatic at first. As the disease progresses symptoms appear, if symptoms are present then there is already irreversible damage to the eye. There is no cure for Glaucoma, treatment is aimed at slowing the progression of the disease. Diagnostic tests done to detect Glaucoma are; measuring IOP, evaluation of

The purpose of the current study is to evaluate whether there are different patterns of RNFL thinning among the different subtypes of open angle glaucoma and also to compare these glaucoma patients with normal patients who had been imaging with Spectralis spectral domain OCT (Heidelberg

During the assessment of the eye, visual accuity tested by reading material outloud, No problem noted,

Surgical treatment has been proven to improve the visual acuity (Reacher et al., 1992), but its effectiveness on cornea opacity

A history and performing an examination needs to be completed by the nurse practitioner (NP) to evaluate the patients symptoms and complaints. The NP should ask questions that pertain to onset and duration of symptoms, as well as anything that triggers or alleviates them. The NP should also take note of the patient’s medical history that includes any familial tendencies towards CAG. Medication will need evaluated as in some cases this can cause the patient to experience symptoms of CAG. Further examination of the patient may reveal a mid-dilated nonreactive pupil, corneal edema, and anterior chamber inflammation. Tonometry will need to be done to measure intraocular pressure (IOP), and an IOP in the range of forty to ninety millimeters of mercury (mm/Hg) may indicate CAG where as normal pressure ranges from fourteen to sixteen mm/Hg. The test is normally performed by an optometrist as is required anesthetic drops (American Optometric Association, 2011). Evaluation of the anterior chamber angle depth should be performed as part of the eye examination and can be done using the pen light shadow test or the lateral pen test. To perform this test, the NP shines the pen light into the eye on the lateral side of the patent’s head next to the temple. The NP is visually looking for the light to illuminate the iris of the eye. If the NP visualizes a shadow, this would be an indicator of increase ocular pressure related to glaucoma

As of now, nearly 90% of people living in Asia are vulnerable of developing the condition that can lead to diseases like glaucoma, macular degeneration and cataract. It is to be noted that back in the 90s, evidences were found that atropine in eye drops could reduce nearsightedness. However, this had some effects.

Fellow eye is affected weeks or months after the involvement of the first eye. In acute stages, disc hyperemia and telangiectatic microangiopathy are evident. In chronic cases, severe optic atrophy supervenes. However, it is associated with brisk pupillary light reflexes.(12)

The claimant has a history of vision issues. At the consultative exam on 8/9/17, she had best corrected acuities of 20/20 in the right eye (OD) and 20/30+2 in the left eye (OS) with abnormal funduscopic findings consistent with retinitis pigmentosa. The Humphrey field vision 30-2 OD had the widest diameter which was less than 20 degrees. The OS widest diameter was actually 24%.
