Purpose : Inability to drive is a major concern for patients with glaucoma. The purpose of this study was to examine the longitudinal relationship between rate of change in RNFL thickness and change in ability to divide attention during a simulated driving task. Methods : 152 glaucoma patients were followed for an average of 3.7 years. At each visit investigations included visual acuity, contrast sensitivity, perimetry and optical coherence tomography (OCT). Ability to divide attention was assessed using a driving simulator to measure reaction times to stimuli presented simultaneously during two central tasks 1) curve negotiation and 2) car following. A joint longitudinal multivariate mixed model was used to investigate the association between rates of change in driving performance and RNFL thickness over time. Reaction time values were positively skewed therefore natural logarithms were calculated. The effect of potentially confounding variables including integrated binocular visual field ...

Purpose: : To evaluate whether screening with FDT-perimetry is of predictive value for progression of optic nerve damage in glaucoma suspects and early glaucomas. Progression was defined morphometrically (2D), results were compared to HRT measurements. Methods: : The longitudinal observational clinical study includes 438 preperimetric patients, OHT patients, and glaucoma suspects from the Erlangen Glaucoma Registry. Inclusion criteria at baseline: visual acuity better 20/40, refractive error between -8 and +6 D, age: 30-72 years. All subjects had normal white-on-white perimetry at baseline (Octopus, mean defect less than 2dB). Two or more annual visual field examinations using FDT-screening were performed. FDT evaluation used a published method with casewise calculation of an FDT-score, including missed localized probability levels in all stimulus fields and in quadrants. For prospective analysis of the predictive value of FDT, the first measurement was always discarded because of learning ...

Purpose: To investigate whether the prevalence GSTT1 and GSTM1 deletion genotypes (T0M1, T1M0, and T0M0) are increased in certain spontaneous optic neuropathies.. Methods: We compared the prevalence of GSTT1 and GSTM1 deletion genotypes in 108 Arab patients with optic neuritis (ON, 26 patients), LHON-like optic neuropathy (LLON, 35 patients), sporadic bilateral optic neuropathy in children (SBON, 21 patients), and non-arteritic ischemic optic neuropathy (NAION, 26 patients) to 120 ethnicity matched controls. Genotypes were determined by multiplex polymerase chain reaction.. Results: All three GST deletion genotypes were significantly more prevalent in the entire optic neuropathy group than in controls. When patients were stratified by optic neuropathy type, the prevalence of at least one deletion genotype was significantly increased in each type of optic neuropathy.. Conclusions: These results imply that GST malfunction in the setting of GST deletion genotypes may interfere with metabolism of ...
In myopic eyes, it is believed that the assessment of RNFL thickness by SLP should be conducted with caution because of the incidence of ARP. However, there is a paucity of reports that describe the details of SLP assessment of myopic glaucomatous eyes. In the study described herein, we conducted RNFL measurement using both GDx VCC and GDx ECC, and have shown the results of SLP assessment of myopic glaucomatous eyes. As is expected in myopic eyes, we noted that with GDx VCC, myopic glaucomatous eyes, especially highly myopic eyes, showed an ARP in many cases. Although the definition of ARP was not identical between studies, the prevalence of ARP (TSS less than 80) in our study, 14/40 (35.0%) of the moderately and 19/35 (54.3%) of the highly myopic eyes, was higher than that in previous studies, most of which were conducted in populations without highly myopic eyes. According to previous reports, the prevalence of ARP was between 7 and 51%,13 16 17 19 and TSS values were between 71.2 and ...

The swinging light test is used to detect a relative afferent pupil defect (RAPD): a means of detecting differences between the two eyes in how they respond to a light shone in one eye at a time. The test can be very useful for detecting unilateral or asymmetrical disease of the retina or optic nerve (but only optic nerve disease that occurs in front of the optic chiasm).
The optic nerve contains retinal ganglion cell axons that extend posteriorly from the globe, through the orbit and optic canal, to reach the optic chiasm. The total length of the optic nerve averages 50 mm: 1 mm for the intraocular segment, 25 mm for the intraorbital segment, 10 mm for the intracanalicular segment, and 14 mm for the intracran...

Neuro-ophthalmology is a field of medicine that touches on every subspecialty in neurology, but has an undeserved reputation as a branch of knowledge that is difficult to learn and practice. Many neurologists and ophthalmologists do not receive sufficient exposure to neuro-ophthalmology during their residencies, and are uncomfortable diagnosing and treating patients with neuro-ophthalmic problems.

Healthy optic nerve head. The National Eye Institute has awarded a $5 million research grant to UC Davis ophthalmologist John S. Werner and researchers at three other universities to continue the development of technology for three-dimensional imaging of cells in the living eye.. The studies, part of the next, five-year phase of the Bioengineering Research Partnership, could benefit the approximately 20 percent of Americans above the age of 60 suffering from the sight-threatening consequences of age-related macular degeneration and glaucoma. It would provide significant advances in understanding the origins of retinal and optic nerve disease and in evaluating novel therapies for a wide spectrum of human blinding diseases.. "Our project has been described as the Hubble telescope of the eye," said Werner, the projects principal investigator and a professor at the UC Davis Health System Eye Center..

Following initial tests and their purpose are summarized below. Vision. A Snellen chart is used to measure distance vision with your distance glasses.. It is helpful to bring your current glasses and prescription if available.. Colour vision. A specialized chart called Ishihara chart is used to check the colour vision. This is useful to differentiate causes of vision loss due to glaucoma and other optic nerve diseases. In glaucoma colour vision is preserved till late in the course of the disease.. Visual fields. This tests the periphery of the vision. Head is placed inside a large bowl and lights are flashed in the periphery. You then press a button when you see the lights while looking at the central fixation light. The same process is repeated with the other eye.. Slit lamp examination. This is the microscope like instrument that is used in all routine eye examinations. It shines a light in to the eye and the doctor looks at the front and the back of the eye through it. This gives a magnified ...

Optic neuritis is diagnosed based on clinical symptoms and signs, so it is not rare to misdiagnose a disease as an optic neuritis, especially the retrobulbar type. In this case, there were several clues that were misleading. First of all, there was no proptosis in appearance, no headache from history, and the visual loss was relatively quick compared with the "traditional image" of a brain tumor. These did not lead us to an impression of a brain tumor.. Compressive optic neuropathy caused by a suprasellar tumor is not rare at all. Generally speaking, there are signs such as proptosis, disc swelling, headache, progressively deterioration of visual symptoms, or other neurological signs. These were not obviously found in this particular patient, who finally was proved to be a case of compressive optic neuropathy caused by a suprasellar meningioma.. Another interesting point in this case was the rapid and excellent response to intravenous methylprednisolone, which is also seen in optic neuritis ...
The cup-to-disc ratio (often notated CDR) is a measurement used in ophthalmology and optometry to assess the progression of glaucoma. The optic disc is the anatomical location of the eyes "blind spot", the area where the optic nerve and blood vessels enter the retina. The optic disc can be flat or it can have a certain amount of normal cupping. But glaucoma, which is in most cases associated with an increase in intraocular pressure, often produces additional pathological cupping of the optic disc. The pink rim of disc contains nerve fibers. The white cup is a pit with no nerve fibers. As glaucoma advances, the cup enlarges until it occupies most of the disc area.[1] The cup-to-disc ratio compares the diameter of the "cup" portion of the optic disc with the total diameter of the optic disc. A good analogy to better understand the cup-to-disc ratio is the ratio of a donut hole to a donut. The hole represents the cup and the surrounding area the disc. If the cup fills 1/10 of the disc, the ratio ...
A Relative Afferent Pupillary Defect is an examination finding in patients who have an asymmetric pupillary reaction to light when it is shined back and forth between the two eyes. It is most commonly a sign of asymmetric optic nerve disease or damage but can also present in widespread asymmetric r ...
A computer perimetry (also known as a visual field) tests the entire scope of your peripheral (side) vision.. This test is frequently used to detect any sign of glaucoma damage to the optic nerve. In addition, perimetry tests are also useful for detecting central or peripheral retinal disease, eyelid conditions such as ptosis or drooping, optic nerve disease and disease affecting the visual pathways within the brain.. The perimetry test is performed one eye at a time with the other eye completely covered to avoid errors. You will be asked to look directly ahead at all times to avoid testing the central vision rather than the peripheral vision.. On your first visit to the ophthalmologist, with signs of glaucoma, the ophthalmic technicians will perform a perimetry test collating the results for the ophthalmologist to view during your consultation. This initial test is commonly referred to as your base line test. This enables the ophthalmologist to form a starting point and then at regular ...
This case is unusual because the intra-abdominal cyst seems to have caused hypertension and bilateral disc swelling in the absence of common funduscopic signs of hypertensive retinopathy. Whereas polycystic ovarian syndrome is known to cause hypertension through hemodynamic alterations and variations in peripheral vascular resistance, it is uncommon for bilateral disc swelling to be a presenting feature.(5,6) Moreover, the presence of a large solitary ovarian cyst does not fulfill the criteria of PCOS diagnosis.(7) We hypothesize that the size of the ovarian cyst may have had a role in compressing the renal veins, thus causing an associated hypertension and bilateral optic neuropathy ...
A variety of strategies can be used to both protect and repair damaged optic nerves; however, work currently advances slowly, in part because of the need to thoroughly test such strategies in at least two species of animals before trying them in humans and in part because of the considerable cost involved in animal research. Nevertheless, with funding from institutions such as the National Eye Institute of the National Institutes of Health and the Hirschhorn Foundation as well as from individual donors, we have been able to develop reproducible models of optic nerve damage in rats, mice, and, most importantly, in monkeys. These models allow us to test various substances that have the potential to reduce the amount of optic nerve damage caused by various insults or to restore vision that is lost from optic nerve damage. With this knowledge, we can then begin testing on humans. ...
