Evaluation of focal defects of the nerve fiber layer using optical coherence tomography. (1/2548)

OBJECTIVE: To analyze glaucomatous eyes with known focal defects of the nerve fiber layer (NFL), relating optical coherence tomography (OCT) findings to clinical examination, NFL and stereoscopic optic nerve head (ONH) photography, and Humphrey 24-2 visual fields. DESIGN: Cross-sectional prevalence study. PARTICIPANTS: The authors followed 19 patients in the study group and 14 patients in the control group. INTERVENTION: Imaging with OCT was performed circumferentially around the ONH with a circle diameter of 3.4 mm using an internal fixation technique. One hundred OCT scan points taken within 2.5 seconds were analyzed. MAIN OUTCOME MEASURES: Measurements of NFL thickness using OCT were performed. RESULTS: In most eyes with focal NFL defects, OCTs showed significant thinning of the NFL in areas closely corresponding to focal defects visible on clinical examination, to red-free photographs, and to defects on the Humphrey visual fields. Optical coherence tomography enabled the detection of focal defects in the NFL with a sensitivity of 65% and a specificity of 81%. CONCLUSION: Analysis of NFL thickness in eyes with focal defects showed good structural and functional correlation with clinical parameters. Optical coherence tomography contributes to the identification of focal defects in the NFL that occur in early stages of glaucoma.  (+info)

Out of 102 glaucomatous eyes 78 became relatively myopic, and this appears to be due to changes in the dimensions of the lens of the eye similar to those occurring in accommodation, as a result of the effect of the drug on the ciliary muscle. The effect of pilocarpine on anterior chamber depth, area, and volume was studied in 125 eyes using a photographic method, and a significant reduction in the dimensions of the anterior chamber was observed as a result of the administration of pilocarpine. A significant correlation between depth and volume was also noted and the implications of this are discussed.  (+info)

Rapid pneumatic and Mackey-Marg applanation tonometry to evaluate the postural effect on intraocular pressure. (3/2548)

A postural study was conducted in three separate groups of subjects. The first group comprised 20 women volunteers with an average age of 20-75 years. In this group, the study was conducted by the pneumatonograph only. Mean pressure recorded was 15-65 +/- 0-25 mmHg and there was an average rise of 1-4 mmHg in supine posture. Groups 2 and 3 comprised 151 non-glaucomatous and 108 glaucomatous eyes respectively in the age range of 30 to 85 years. In these two groups, the study was conducted using the PTG and the Mackay-Marg tonometer. Clinical evaluation of the Mackay-Marg with the PTG gave significant correlation, with mean Mackay-Marg readings being 1-13 mmHg higher. The intraocular pressure when changing from seated to the supine position increased on average by 2-71 and 4-04 mmHg, respectively in Groups 2 and 3 and by 2-51 and 3-72 mmHg by Vackay-Marg, suggesting a higher change in glaucomatous subjects. Pressure on resumption of sitting was found to be lower than the initial pressure. Postural change also showed some direct relationship with age in non-glaucomatous subjects.  (+info)

Chronic retinal vein occlusion in glaucoma. (4/2548)

Asymptomatic chronic retinal vein occlusion that occurs in chronic simple glaucoma is described. The condition is characterized by marked elevation of retinal vein pressure with collateral vessels and vein loops at the optic disc in cases of central vein occlusion, or retinal veno-venous anastomoses along a horizontal line temporal and nasal to the disc in hemisphere vein occlusion. No patient had visible arterial changes, capillary closure, fluorescein leakage, or haemorrhages. The vein occlusion was not limited to "end stage" glaucoma. The role of increased intraocular pressure and glaucomatous enlargement of the optic cup with retinal vein distortion in the pathogenesis of the condition was stressed. Follow-up of these patients revealed persistence of the retinal vein occlusion shown by elevated retinal vein pressures. This would reduce effective perfusion of the inner retina and optic disc and may affect the long-term visual prognosis.  (+info)

The optic disc in glaucoma. I: Classification. (5/2548)

Five different descriptive types of glaucomatous optic discs are described, based on the examination of X2 magnification stereophotographs of 252 patients from the files of the Glaucoma Service at Wills Eye Hospital. The method of analysis is described in detail. These types include: overpass cupping, cupping without pallor of the neuroretinal rim, cupping with pallor of the neuroretinal rim, focal notching of the neuroretinal rim, and bean-pot cupping. These morphological types may be caused by variations in factors contributing to the pathogenesis of glaucomatous eyes. Recognition of these differing types may help in determining the factors in each case.  (+info)

Plasma cortisol suppression response in the South African black population with glaucoma. (6/2548)

Plasma cortisol suppression was measured in 25 Black glaucomatous patients and in 19 Black patients of similar age and sex, but without glaucoma, who acted as controls. Initial serum cortisol levels were found to be slightly higher in the glaucomatous group. The response to systemically-administered cortisone was statistically more marked in the glaucomatous patients compared with the control group.  (+info)

Analysis of myocilin mutations in 1703 glaucoma patients from five different populations. (7/2548)

A glaucoma locus, GLC1A, was identified previously on chromosome 1q. A gene within this locus (encoding the protein myocilin) subsequently was shown to harbor mutations in 2-4% of primary open angle glaucoma patients. A total of 1703 patients was screened from five different populations representing three racial groups. There were 1284 patients from primarily Caucasian populations in Iowa (727), Australia (390) and Canada (167). A group of 312 African American patients was from New York City and 107 Asian patients from Japan. Overall, 61 different myocilin sequence variations were identified. Of the 61 variations, 21 were judged to be probable disease-causing mutations. The number of probands found to harbor such mutations in each population was: Iowa 31/727 (4.3%), African Americans from New York City 8/312 (2.6%), Japan 3/107 (2.8%), Canada 5/167 (3.0%), Australia 11/390 (2.8%) and overall 58/1703 (3. 4%). Overall, 16 (76%) of 21 mutations were found in only one population. The most common mutation observed, Gln368Stop, was found in 27/1703 (1.6%) glaucoma probands and was found at least once in all groups except the Japanese. Studies of genetic markers flanking the myocilin gene suggest that most cases of the Gln368Stop mutations are descended from a common founder. Although the specific mutations found in each of the five populations were different, the overall frequency of myocilin mutations was similar ( approximately 2-4%) in all populations, suggesting that the increased rate of glaucoma in African Americans is not due to a higher prevalence of myocilin mutations.  (+info)

Evaluation of ocular arterial changes in glaucoma with color Doppler ultrasonography. (8/2548)

The purpose of this study was to evaluate hemodynamic changes of the retrobulbar vasculature caused by different intraocular pressures with color Doppler ultrasonography. Fifty normal eyes in 25 patients, 13 patients with normal tension glaucoma, and 19 patients with acute glaucoma and increased intraocular pressure (greater than 30 mm Hg) were enrolled in this study. In 15 of 19 patients with acute glaucoma patients, follow-up color Doppler ultrasonography was also undertaken after laser peripheral iridectomy when the intraocular pressure had returned to normal. The peak systolic velocity, end diastolic velocity, resistive index, time average maximum velocity, and pulsatility index were compared in different vessels, including the central retinal artery, lateral posterior ciliary artery, medial posterior ciliary artery, and ophthalmic artery in each orbit. The peak systolic velocity, end diastolic velocity, and time average maximum velocity of the central retinal artery were significantly lower (P<0.01) in acute glaucoma patients than in the control group. The resistive index and pulsatility index of the central retinal artery were significantly higher (P<0.01) in acute glaucoma patients than in the control group. The end diastolic velocity of the lateral and medial posterior ciliary arteries was significantly lower in patients with acute glaucoma than in the control group, and the resistive index and pulsatility index of both of these arteries were significantly higher (P<0.001) in patients with acute glaucoma than in the control group. However, no statistical significantly differences were found in the peak systolic velocity or time average maximum velocity in either of the posterior ciliary arteries; similarly, no statistically significant differences were noted in any of the parameters in the ophthalmic artery between the control group and the group with acute glaucoma. The pulsatility index of the central retinal artery and of the lateral and medial posterior ciliary arteries was significantly lower (P<0.01) in acute glaucoma patients after laser therapy than in acute glaucoma patients before laser therapy. The resistive index of both posterior ciliary arteries was also significantly lower (P<0.004) in acute glaucoma patients after laser therapy than before laser therapy. All parameters for all vessels examined among the normal subjects, the patients with normal tension glaucoma, and the patients with acute glaucoma after laser therapy when the intraocular pressure had returned to normal showed no statistically significant differences. Color Doppler ultrasonography is a good modality for both imaging and studying the hemodynamics of the perioptic nerve vessels.  (+info)

Another name for Acute Glaucoma is Acute Glaucoma. What to expect with acute glaucoma: * Most cases of acute glaucoma respond very well to treatment. ...
Acute glaucoma, characterized by a sudden elevation in intraocular pressure (IOP) and retinal ganglion cells (RGCs) death, is a major cause of irreversible blindness worldwide that lacks approved effective therapies, validated treatment targets and clear molecular mechanisms. We sought to explore the potential molecular mechanisms underlying the causal link between high IOP and glaucomatous RGCs death. A murine retinal ischemia/ reperfusion (RIR) model and an in vitro oxygen and glucose deprivation/reoxygenation (OGDR) model were used to investigate the pathogenic mechanisms of acute glaucoma. Our findings reveal a novel mechanism of microglia-induced pyroptosis-mediated RGCs death associated with glaucomatous vision loss. Genetic deletion of gasdermin D (GSDMD), the effector of pyroptosis, markedly ameliorated the RGCs death and retinal tissue damage in acute glaucoma. Moreover, GSDMD cleavage of microglial cells was dependent on caspase-8 (CASP8)-hypoxia-inducible factor-1α (HIF-1α) signaling.

The eye doctor can often (though not always) see whether you are at high risk for acute glaucoma during a regular eye exam. If this is the case, preventive laser therapy can be advised. Women, severely farsighted people, and people with cataract have a greater tendency for developing acute glaucoma than do other people. Certain drugs can also cause this type of glaucoma, mainly comprising those used for common cold, diarrhea, depression and Parkinsons Disease. These drugs do not, however, affect eye pressure in persons with chronic open-angle glaucoma.. ...

N2 - Background: Neuroinflammation-astrogliosis, microglial activation, and changes in cytokine signaling-is a prominent feature of neurodegenerative disorders. Glaucoma is a group of chronic neurodegenerative conditions that make up the leading cause of irreversible blindness worldwide. Neuroinflammation has been postulated to play a significant role in the pathogenesis and progression of glaucomatous neurodegeneration. Though much is known regarding inflammation in the eye in glaucoma, little is known about cytokine activity outside of the retina where pathologies develop early. Methods: We traced the primary visual projection from the eye to the superior colliculus (SC) in DBA/2J and DBA/2J.Gpnmb + (control) mice using the anterograde tracer ...
The conventional wisdom on glaucoma is that, as IOP is the only modifiable risk factor of the disease, it must also be the most reliable bellwether of glaucomatous damage. However, as most glaucoma specialists will tell you, only monitoring IOP will provide an incomplete picture. Some glaucoma patients with low IOP may continue to progress. New research from Stanford University now confirms the most effective way of slowing the progression of glaucoma in a patient with low IOP is to lower the IOP further, sometimes to single digit levels, which is most often achievable with trabeculectomy, according to the investigators.. In a wide-ranging review of studies and clinical trials, researchers in Palo Alto, CA, have found that glaucoma patients require a more comprehensive testing protocol than merely IOP monitoring to establish progression. Their research asserts that large randomized clinical trials demonstrate a tremendous variability in visual field testing, and that greater variability can ...
This clinical trial is a prospective, randomized, controlled, multicenter, study. After informed consent is obtained, patients will be evaluated for eligibility based on glaucoma severity, eye health, and visual acuity. Following successful screening, use of all topical glaucoma medications will be stopped for a period of washout to establish a qualifying medication-free intraocular pressure (IOP) value. Clinical follow up will be scheduled over the course of the 24 month study, and examinations will be repeated to monitor eye health. At the 1 and 2 year follow up, those patients on ocular hypotensive medications will be instructed to washout, and then have the diurnal (IOP taken in the morning, mid-day, and afternoon in the same day) IOP evaluation. Annual follow up will occur up to 5 years. The primary effectiveness endpoint is a decrease in diurnal IOP from baseline compared to the 24 months diurnal IOP following medication washout ...
Background: Glaucoma is associated with visual field loss for which elevated intraocular pressure is the primary risk factor.

Juvenile glaucoma is a rare juvenile-onset open-angle glaucoma (JOAG) often found associated with myopia that shows autosomal dominant transmission. This entity does not include other childhood glaucomas outlined below in the listing of other primary developmental and secondary childhood glaucomas.
Glaucoma is a group of diseases of the optic nerve involving loss of retinal ganglion cells in a characteristic pattern of optic neuropathy. Raised intraocular pressure is a significant risk factor for developing glaucoma (above 22mmHg). One person may develop nerve damage at a relatively low pressure, while another person may have high eye pressure for years and yet never develop damage. Untreated glaucoma leads to permanent damage of the optic nerve and resultant visual field loss, which can progress to blindness.. Glaucoma can be divided roughly into two main categories, open angle or chronic glaucoma and closed angle or acute glaucoma. Angle closure, acute glaucoma appears suddenly and often with painful side effects and so is usually diagnosed quickly, although damage and loss of vision can also occur very suddenly. Open angle, chronic glaucoma tends to progress more slowly and so the patient may not notice it until the disease has progressed quite significantly.. Glaucoma has been ...

Glaucoma is a damage of the optic nerve caused by intraocular pressure. It is one of the main causes of blindness worldwide. The damage is most frequently caused by elevated intraocular pressure, but low pressure and normal pressure glaucoma are also known. In these conditions, the optic nerve is damaged in spite of low intraocular pressure. Damage to the optic nerve caused by glaucoma is irreversible. Early diagnosis and treatment are therefore crucial.. Symptoms. The main symptom of glaucoma is the deterioration of the visual field. Patients will typically be unaware of these until an advanced stage. A visual field test helps to detect a deterioration of the visual field at an early stage allowing early treatment.. In rare cases, elevated intraocular pressure can lead to blurry vision, irritated or red eyes, headaches, and a sensation of pressure in the ocular region or the head.. In most cases, however, glaucoma does not cause any discomfort. This is particularly dangerous as it can prevent ...

Purpose.: To investigate whether topical administration of pirfenidone eye drops could be used to prevent postoperative scarring in a rabbit model of experimental glaucoma filtration surgery. Methods.: In a randomized, controlled, masked-observer study, 40 rabbits underwent trabeculectomy in the right eyes and randomly received postoperative administration of 0.1% or 0.5% pirfenidone, perioperative mitomycin C (0.25 mg/mL), or no treatment. Bleb characteristics and functions were evaluated over a period of 4 weeks. The animals were killed on days 7, 14, and 28. Histopathology and immunohistochemistry were performed to determine the amount of scarring and fibrosis. Ocular toxicity was assessed by the Draize test, histopathology, and electron microscope. Results.: The four treatment groups were similar with respect to intraocular pressure and anterior chamber depth. Pirfenidone 0.5% significantly prolonged bleb survival, and the blebs were larger and higher than those in the control group (P , ...
A grid system is described which may be superimposed upon stereoscopic pairs of optic disc photographs. This grid system allowed reproducible inter- and intraobserver measurements of the cup/disc (C/D) ratio. The surface contour of the optic disc was not clear-cut in approximately 10% of the population studied, which led to a reduction in reproducibility of the measurement made within the group as a whole. As a result it was found that a large increase in the C/D ratio would have to occur for such change to be of statistical significance. Even with an optic grid as a reference system the serial measurements of the C/D ratio are unlikely to be of value in the management of patients with chronic glaucoma. ...
In the present study, RNFL retardation measurements obtained with the SLP were significantly higher in normal eyes compared with glaucomatous eyes, although there is a considerable overlap between both groups. The symmetry parameter was the only measurement not significantly different between the groups (p = 0.12). These findings are consistent with previous studies that stressed the large range of normal mean values of retardation.101618-20. Although the mean age was different among the groups, it did not influence our LDF analysis to discriminate between normal and glaucomatous eyes, as it proved to be a weak variable to be used in the LDF formula.. All individual SLP parameters showed low sensitivities and high specificities when the NFA/GDx database was used as reference and none of the individual RNFL measurements could correctly assign as outside normal limits the majority of glaucoma cases. There are two possible explanations for this finding. Firstly, the normative database may be ...

Minimally invasive glaucoma surgery (MIGS) has been a buzzword in glaucoma management for years, offering patients with mild to moderate glaucoma a middle ground between topical drops and filtration surgery. Today, more than 15 different options grace surgical suites across the globe.1 Yet another device, the Miniject (iStar Medical), has hit the clinical trial scene in Europe. The Miniject is a 5mm long device made of porous silicone that improves aqueous outflow to the suprachoroidal space, according to the study.. Researchers in India and Panama recently implanted the device, as a stand-alone procedure, in 25 primary open-angle glaucoma eyes. The average baseline status was IOP of 23.2mm Hg and an average of 2.0±1.1 IOP-lowering medications. During follow-up, the researchers found the device led to a mean drop in IOP of 39.1% six months post-op. Medication use was down as well, to a mean of 0.3±0.7 medications at the six-month follow-up. Of the 24 eyes seen at that visit, 87.5% were ...

To determine whether sNgR-Fc can affect the synaptic input after the induction of ocular hypertension, the c-Fos protein which was transiently expressed in neurons after synaptic stimulation was used as the marker of neuronal connectivity. 23 -27 The expression of c-Fos protein in immunohistochemically stained RGC indicates the intactness of the neural synaptic pathways. A total of 42 animals were used for c-Fos staining (n = 6 for each group). FG labeling of RGCs was performed 7 days before euthanization. The animals treated with sNgR-Fc or PBS were exposed to 30 minutes of ambient light before euthanization and were euthanized with an overdose of anesthesia at 5 days, and 2 and 4 weeks after the first laser coagulation. 26 The eyes were enucleated after transcardial perfusion with 0.9% saline and were fixed in 4% PFA for 1 hour. After removing the corneas and lens, the eyecups were fixed further in PFA for 4 hours and then transferred to 30% sucrose solution at 4°C for 16 hours. ...

Treatment. Glaucoma treatment reduces the pressure in the eye, and this can be done with eye drops, laser treatment or surgery, but early detection of the condition is important because any damage cannot be reversed - the aim of treatment is to prevent or slow down further damage to the eye.. A regular Eye Examination will help to ensure that glaucoma is diagnosed early so that treatment can start. Without treatment glaucoma can eventually lead to blindness.. Glaucoma can be treated under the NHS at the Eye Unit, and in Dorset certain patients with glaucoma may be eligible for the Shared Eyecare Scheme. This is an arrangement whereby you can attend for your glaucoma follow up appointments with us instead of having to attend the Eye Unit. The results of your appointment are sent back to the Eye Unit who decide if your glaucoma is stable or not. If it is stable the Eye Unit will probably continue to allow you to be seen on the Shared Eyecare Scheme, but if your treatment needs changing we are not ...

Canaloplasty is another state of the art procedure that is an alternative to traditional Glaucoma surgery. The Canaloplasty procedure is available alone or concurrent with cataract extraction to reduce eye pressure and the number of glaucoma medications used by patients. It is a non-penetrating surgical procedure that does not require the creation of a fistula and does not result in a bleb. Insertion of a microcathether using the outflow system of the eye and suture tension within this system controls pressure.. Dr. Pappas is one of few in the USA, the first in Florida, and the only one in Brevard County to have performed hundreds of procedures since 2008.. Due to the excellent results with this procedure, in 2009 Dr. Pappas and the Pinnacle Eye Center were instrumental in getting CMS to approve this procedure for Medicare patients in Florida.. ...
Visual Field testing ( perimetry ) is useful but often the first test is unreliable.. Someone should stay in room with patient and have them look straight ahead. The test is worthless if patient is looking all around. The patient needs to be instructed on how to take the test. Give patient a photocopy of the results. If we dont check the IOP then not likely to diagnosis early or moderate glaucoma with no symptoms.. In patients with glaucoma, the IOP should be check on each visit. Checking the IOP regularly is the best test we can do for glaucoma patients. Once is not enough.. Patients with African ancestry should have IOP checked starting at age 20 years. Pts with African ancestry often have a more aggressive disease and are more difficult to treat / control. Glaucoma often runs in families and therefore other family members need to be checked even if living overseas.. Patients with severe optic nerve damage need their IOP lower to prevent further progression ( damage ).. Patients should be ...

Glaucoma is more common in people over 40, but Congenital Glaucoma - though more rare - can occur (obviously, since its what I have). If caught early enough most types of Glaucoma are able to be at least stopped from progressing (well, in a lot of cases anyway) but not generally Congenital Glaucoma. As a general rule, the best you can hope for with Congenital Glaucoma is that you can find the right combination of medication (eye drops, etc) to buy you as much time with eyesight as possible ...

  • As the cause of primary glaucoma is often unknown, medical treatment is usually aimed at reducing the main sign of glaucoma (raised intraocular pressure) rather than at treating the cause of the disease. (
  • The aim of surgery in dogs with glaucoma is to reduce intraocular pressure. (
  • This underdevelopment of the front of the eye, known as anterior segment dysgenesis (which includes Peters' anomaly), can lead to an increased risk of glaucoma from high intraocular pressure, due to impaired eye fluid drainage, though this hadn't been reported in any of the affected individuals as of 2017[update].

  • Primary acute closed-angle glaucoma results from a buildup of fluid in the eye because the distance between the iris and the drainage system has been closed, stopping fluid from draining from the eye. (
  • Chronic angle closure glaucoma also involves a narrowing of space between the iris and the drainage system but it occurs much more gradually than in the acute form of the condition (and can take weeks or even years). (
  • Acute closed-angle glaucoma occurs with a sudden onset of symptoms such as severe eye pain, blurred vision, nausea, redness in the eye and haloes around lights. (
  • The possibility of 2 forms of phacolytic glaucoma was proposed in a recent report: (1) a more acute presentation caused by rapid leakage of lens proteins that occlude the trabecular meshwork and (2) a more gradual presentation with macrophages resulting from an immunologic response to lens proteins in the anterior chamber.

  • Without treatment, people with glaucoma will slowly lose their peripheral, or side vision. (
  • Initially, glaucoma affects peripheral or side vision, but it can advance to central vision loss. (
  • Sight loss from glaucoma usually begins with your peripheral vision, often in the vision closest to the sides of your nose (mid-periphery) first. (
  • However, the number could have been even higher, since some participants with peripheral vision problems didn't undergo all of the tests used to commonly diagnose glaucoma. (
  • 1) Thanks to recent investigations, we are now aware that vision defects in glaucoma patients are not as simple as the traditional view of peripheral vision loss, but they affect several aspects related to a generally decreased image quality including glare, letters appearing faded when reading, and needing more light. (

  • Glaucoma is characterized by a particular pattern of progressive damage to the optic nerve that generally begins with a subtle loss of side vision ( peripheral vision ). (
  • The reason they are unaware of the presence of the disease is that glaucoma initially causes no symptoms, and the subsequent loss of side vision ( peripheral vision) is usually not recognized. (
  • At first, people with glaucoma lose side (peripheral) vision. (
  • When glaucoma damages your optic nerve, you begin to lose patches of vision, usually side vision (peripheral vision). (
  • If a doctor determines that there has been a decline in vision, he or she can measure the pressure inside the eye and check the patient's peripheral and central vision to diagnose glaucoma. (
  • Unfortunately, the visual field loss in glaucoma represents permanent damage to the optic nerve and is therefore irreversible. (
  • Damage to the optic nerve and impairment of vision from glaucoma are irreversible. (
