Retinal Diseases
Retinal Degeneration
A retrogressive pathological change in the retina, focal or generalized, caused by genetic defects, inflammation, trauma, vascular disease, or aging. Degeneration affecting predominantly the macula lutea of the retina is MACULAR DEGENERATION. (Newell, Ophthalmology: Principles and Concepts, 7th ed, p304)
Retina
The ten-layered nervous tissue membrane of the eye. It is continuous with the OPTIC NERVE and receives images of external objects and transmits visual impulses to the brain. Its outer surface is in contact with the CHOROID and the inner surface with the VITREOUS BODY. The outer-most layer is pigmented, whereas the inner nine layers are transparent.
Retinitis Pigmentosa
Hereditary, progressive degeneration of the neuroepithelium of the retina characterized by night blindness and progressive contraction of the visual field.
Photoreceptor Cells, Vertebrate
Specialized PHOTOTRANSDUCTION neurons in the vertebrates, such as the RETINAL ROD CELLS and the RETINAL CONE CELLS. Non-visual photoreceptor neurons have been reported in the deep brain, the PINEAL GLAND and organs of the circadian system.
Electroretinography
Recording of electric potentials in the retina after stimulation by light.
Retinal Pigment Epithelium
The single layer of pigment-containing epithelial cells in the RETINA, situated closely to the tips (outer segments) of the RETINAL PHOTORECEPTOR CELLS. These epithelial cells are macroglia that perform essential functions for the photoreceptor cells, such as in nutrient transport, phagocytosis of the shed photoreceptor membranes, and ensuring retinal attachment.
Leber Congenital Amaurosis
A rare degenerative inherited eye disease that appears at birth or in the first few months of life that results in a loss of vision. Not to be confused with LEBER HEREDITARY OPTIC NEUROPATHY, the disease is thought to be caused by abnormal development of PHOTORECEPTOR CELLS in the RETINA, or by the extremely premature degeneration of retinal cells.

A membrane on the vitreal surface of the retina resulting from the proliferation of one or more of three retinal elements: (1) fibrous astrocytes; (2) fibrocytes; and (3) retinal pigment epithelial cells. Localized epiretinal membranes may occur at the posterior pole of the eye without clinical signs or may cause marked loss of vision as a result of covering, distorting, or detaching the fovea centralis. Epiretinal membranes may cause vascular leakage and secondary retinal edema. In younger individuals some membranes appear to be developmental in origin and occur in otherwise normal eyes. The majority occur in association with retinal holes, ocular concussions, retinal inflammation, or after ocular surgery. (Newell, Ophthalmology: Principles and Concepts, 7th ed, p291)

Color Vision Defects
Defects of color vision are mainly hereditary traits but can be secondary to acquired or developmental abnormalities in the CONES (RETINA). Severity of hereditary defects of color vision depends on the degree of mutation of the ROD OPSINS genes (on X CHROMOSOME and CHROMOSOME 3) that code the photopigments for red, green and blue.
Rod Opsins

An ocular disease, occurring in many forms, having as its primary characteristics an unstable or a sustained increase in the intraocular pressure which the eye cannot withstand without damage to its structure or impairment of its function. The consequences of the increased pressure may be manifested in a variety of symptoms, depending upon type and severity, such as excavation of the optic disk, hardness of the eyeball, corneal anesthesia, reduced visual acuity, seeing of colored halos around lights, disturbed dark adaptation, visual field defects, and headaches. (Dictionary of Visual Science, 4th ed)
Polymorphism, Single-Stranded Conformational
Variation in a population's DNA sequence that is detected by determining alterations in the conformation of denatured DNA fragments. Denatured DNA fragments are allowed to renature under conditions that prevent the formation of double-stranded DNA and allow secondary structure to form in single stranded fragments. These fragments are then run through polyacrylamide gels to detect variations in the secondary structure that is manifested as an alteration in migration through the gels.

Cloned cells in which this DNA alteration is successful are then injected into mouse EMBRYOS to produce chimeric mice. The chimeric mice are then bred to yield a strain in which all the cells of the mouse contain the disrupted gene. Knockout mice are used as EXPERIMENTAL ANIMAL MODELS for diseases (DISEASE MODELS, ANIMAL) and to clarify the functions of the genes.

In vitro method for producing large amounts of specific DNA or RNA fragments of defined length and sequence from small amounts of short oligonucleotide flanking sequences (primers). The essential steps include thermal denaturation of the double-stranded target molecules, annealing of the primers to their complementary sequences, and extension of the annealed primers by enzymatic synthesis with DNA polymerase. The reaction is efficient, specific, and extremely sensitive. Uses for the reaction include disease diagnosis, detection of difficult-to-isolate pathogens, mutation analysis, genetic testing, DNA sequencing, and analyzing evolutionary relationships.
Enzyme-Linked Immunosorbent Assay
An immunoassay utilizing an antibody labeled with an enzyme marker such as horseradish peroxidase. While either the enzyme or the antibody is bound to an immunosorbent substrate, they both retain their biologic activity; the change in enzyme activity as a result of the enzyme-antibody-antigen reaction is proportional to the concentration of the antigen and can be measured spectrophotometrically or with the naked eye.

Histologic analysis of photochemical lesions produced in rhesus retina by short-wave-length light. (1/1813)

The photopathology of retinal lesions produced by extended exposure (1000 sec) to low corneal power levels (62 microW) of blue light (441 nm) was investigated by light microscopy in 20 rhesus eyes over an interval ranging from 1 hr to 90 days after exposure. Results indicate a nonthermal type of photochemical lesion originating in the retinal pigment epithelium and leading to a histological response with hypopigmentation which requires 48 hr to appear.

Aging rhesus monkeys, both controls and those undergoing long-term administration of investigational oral contraceptive steroids, developed widespread hyperfluorescent dots at the posterior pole. The dots were considered to represent drusen. Histologic (including electron microscopic) study showed the "drusen" in some of the animals to be almost exclusively pigment epithelial windows produced by a lipoidal degeneration of the pigment epithelial cells. The experiment provided a fortuitous model for direct correlation of clinical and histologic observations of myriad uniform, tiny, depigmented, hyperfluorescent, nonleaking spots at the level of the retinal pigment epithelium.  (+info)

Necrosis and apoptosis after retinal ischemia: involvement of NMDA-mediated excitotoxicity and p53. (3/1813)

PURPOSE: Accumulated evidence has shown that apoptosis and necrosis contribute to neuronal death after ischemia. The present study was performed to study the temporal and spatial patterns of neuronal necrosis and apoptosis after ischemia in retina and to outline mechanisms underlying necrosis and apoptosis. METHODS: Retinal ischemia was induced by increasing intraocular pressure to a range of 160 mm Hg to 180 mm Hg for 90 minutes in adult rats. The patterns of neuronal cell death were determined using light and electron microscopy and were visualized by TdT-dUTP nick-end labeling (TUNEL). The mRNA expression profile of p53 was examined using reverse transcription-polymerase chain reaction (RT-PCR) and in situ hybridization histochemistry. Immunohistochemistry was performed using anti-p53, anti-microtubule associated protein-2, and anti-glial fibrillary acidic protein antibodies. RESULTS: Within 4 hours after ischemia, neurons in the inner nuclear cell layer (INL) and ganglion cell layer (GCL) underwent marked necrosis, made apparent by swelling of the cell body and mitochondria, early fenestration of the plasma membrane, and irregularly scattered condensation of nuclear chromatin. After 3 days, the INL and GCL neurons showed further degeneration through apoptosis marked by cell body shrinkage, aggregation, and condensation of nuclear chromatin. Apoptotic neurons were also observed sparsely in the outer nuclear cell layer. Intravitreal injections of MK-801 prevented early neuronal degeneration after ischemia. Of note, mRNA and protein levels of p53, the tumor suppressor gene known to induce apoptosis, were increased in the retinal areas undergoing apoptosis 1 to 3 days after ischemic injury. CONCLUSIONS: Ischemia produces the N-methyl-D-aspartate-mediated necrosis and slowly evolving apoptosis of neurons in the retina. The latter may depend on the expression of the p53 proapoptosis gene.  (+info)

Idiopathic central serous chorioretinopathy. (4/1813)

Idiopathic central serous chorioretinopathy (ICSC) is usually seen in young males with Type A personality. Clinical evaluation of the macula with fundoscopy and biomicroscopy, coupled with fluorescein angiography establishes the diagnosis. Indocyanine green angiographic studies have reinformed that the basic pathology lies in choriocapillaries and retinal pigment epithelium. Most of the ICSC resolve completely in four months, and some of them could resolve early with direct photocoagulation of the leaking site. Oral steroids have no role, and could even cause an adverse reaction.  (+info)

Rapid pneumatic and Mackey-Marg applanation tonometry to evaluate the postural effect on intraocular pressure. (5/1813)

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. (6/1813)

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)

Apoptosis and caspases after ischemia-reperfusion injury in rat retina. (7/1813)

PURPOSE: Extensive cell loss in the retinal ganglion cell layer (RGCL) and the inner nuclear layer (INL) was noted in a rat model of retinal ischemia-reperfusion injury by transient elevated intraocular pressure (IOP). The possible involvement of apoptosis and caspases was examined in this model of neuronal loss. METHODS: Transient elevated IOP was induced in albino Lewis rats through the insertion of a needle into the anterior chamber connected to a saline column. Elevated IOP at 110 mm Hg was maintained for 60 minutes. Groups of animals were euthanatized at various times after reperfusion, and their retinas were evaluated by morphology, agarose gel electrophoresis of DNA, in situ terminal deoxynucleotidyl transferase-mediated biotin-deoxyuridine triphosphate nick-end labeling (TUNEL), immunohistochemistry of caspases II (ICH1) and III (CPP32), and morphometry. YVAD.CMK, a tetrapeptide inhibitor of caspases, was used to examine the involvement of caspases. RESULTS: A marked ladder pattern in retinal DNA gel analysis, typical of internucleosomal DNA fragmentation and characteristic of apoptosis, was present 12 and 18 hours after reperfusion. Labeling of nuclei in the RGCL and the inner nuclear layer (INL) by TUNEL was noted between 8 and 18 hours after reperfusion. Histologic and ultrastructural features typical of apoptosis were also observed in the inner retina after ischemia. YVAD.CMK administered during the ischemic period inhibited apoptotic fragmentation of retinal DNA and ameliorated the tissue damage. When administered intravitreally 0, 2, or 4 hours after reperfusion, YVAD.CMK was also effective in preserving the inner retina but had no significant effect when administered 6 or 8 hours after reperfusion. The inner retina showed transient elevated immunoreactivity of caspases II and III 4 and 8 hours after reperfusion. CONCLUSIONS: Retinal ischemia-reperfusion after transient elevated IOP induced apoptosis of cells in the retinal ganglion cell layer and the INL. Caspases may have a pivotal role in the early events of the apoptotic pathway(s). Rescue by using anti-apoptotic agents after ischemia-reperfusion is feasible.  (+info)

Retinopathy of prematurity-mimicking retinopathy in full-term babies. (8/1813)

The purpose of this study was to analyze the fundus findings and associated abnormalities in full-term babies with retinopathy of prematurity (ROP)-mimicking retinopathy. In twenty-seven such babies suffering from this condition, retinal findings were retrospectively analyzed. These babies were not premature and had not required supplementary oxygen; there was no family history of the disease, and no known causes. Bilaterality and severity of retinopathy were compared between groups with associated systemic abnormalities and those without. Forty eyes in twenty-seven full-term babies had abnormal retinal findings; dragged retina accounted for 42.5%, and falciform retinal fold for 47.5%, and retrolental membrane for 10%. Nine babies had associated brain abnormalities, and in these, severe bilateral retinopathy was more likely to occur than in those without abnormalities. These results suggest that if full-term babies have associated abnormalities of the brain, the presence of retinopathy should be ascertained postnatally by cautious examination of the retina.  (+info)

N2 - PURPOSE: Purtschers retinopathy is a rare condition that is associated with complement-activating systemic diseases such as acute pancreatitis. After pancreatic injury or inflammation, proteases such as trypsin activate the complement system and can potentially cause coagulation and leukoembolization of retinal precapillary arterioles. Specifically, intermediate-sized emboli are sufficiently small enough to pass through larger arteries yet large enough to remain lodged in precapillary arterioles and cause the clinical appearance of Purtschers retinopathy. This pathology may present with optic nerve edema, impaired visual acuity, visual field loss, as well as retinal findings such as ...

Cotton wool spots - WikipediaCotton wool spots - Wikipedia
Cotton wool spots are an abnormal finding on funduscopic exam of the retina of the eye. They appear as fluffy white patches on the retina. They are caused by damage to nerve fibers and are a result of accumulations of axoplasmic material within the nerve fiber layer. There is reduced axonal transport (and hence backlog and accumulation of intracellular products) within the nerves because of the ischemia. This then causes the nerve fibers to be damaged by swelling in the surface layer of the retina. A 1981 analysis concluded that in most instances, cotton-wool spots do not represent the whole area of ischaemic inner retina but merely reflect the obstruction of axoplasmic flow in axons crossing into much larger ischaemic areas.[1] Associated findings include microvascular infarcts and hemorrhages. The appearance of cotton wool spots may decrease over time. Abundant cotton wool spots are seen in Malignant hypertension.. Diabetes and hypertension are the two most common diseases that cause these ...

How Gene Therapy Treats Inherited Retinal Diseases - Eye Pain
The U.S Food and Drug Administration in October 2017 revealed their plans to recommend gene therapy as a way to treat inherited retinal diseases. These diseases usually cause a gradual loss of sight that eventually leads to total blindness.. What are Inherited Retinal Diseases (IRDs)?. Inherited retinal diseases (IRDs) are rare eye problems that are caused by mutations that occur in the RPE65 gene. These types of gene mutations are hereditary and responsible for specific conditions that include Lebers congenital amaurosis and some forms of retinitis pigmentosa. Gene therapy can be used to treat these eye disorders.. How gene therapy can treat inherited retinal diseases. People suffering from various types of inherited retinal diseases either have genes that dont work, or are missing. Gene therapy can be used to treat these diseases by adding new genes to their cells to replace the missing or dysfunctional ones.. Usually, they use a specific prepared virus that introduces its own different ...

54-year-old woman was seen in the office on 3/25/2011. She was diagnosed as HIV positive in 1993. Her CD4 count is currently less than 50 and she was hospitalized for pneumocystis carinii pneumonia back in November of 2010. Earlier this month, on March 3rd, she had an episode where she felt strange. She dropped a smoothie and had slurred speech for about ten minutes. Her symptoms completely cleared and it was thought she had a transient ischemic attack. Since then she has had MRI and CT scans, both of which were normal, but she has noticed just for the last few weeks a few blind spots in the paracentral vision. Predominantly out of her right eye when she closes her left eye, she sees a few temporal blind spots. VISUAL ACUITY: Her vision is 20/25 in each eye. IOP: OD 11, OS 12.

To Treat an Inherited Retinal Disease, Its Good to Know Exactly Whats Wrong with the Gene - Eye on the Cure
In simple terms, genes are like recipes for making proteins. All the cells in our bodies read genetic information so they can make the critical proteins necessary to stay healthy and function properly. If there is a mistake in a gene - that is, a misspelling - a protein might not be made correctly and cells in the retina might degenerate and cause vision loss.. These misspellings are called mutations, and just like a mistake in a recipe, some mutations are more devastating than others. For example, when baking a cake, lets say there is an error in the recipe. It incorrectly calls for a quarter cup of sugar, when the right amount is a half of a cup. The cake may not taste great, but it is still edible. But lets say the instruction for adding flour is omitted entirely. Then the cake will be a complete failure and go uneaten.. Well, the same concept applies to genetic mutations in inherited retinal diseases. Some mutations can lead to devastating vision loss while others cause less severe, ...

A Review of the Inflammatory Chorioretinopathies: The White Dot SyndromesA Review of the Inflammatory Chorioretinopathies: The White Dot Syndromes
The white dot syndromes are a group of inflammatory chorioretinopathies of unknown etiology which have in common a unique and characteristic appearance of multiple yellow-white lesions affecting multiple layers of the retina, retinal pigment epithelium (RPE), choriocapillaris, and the choroid. They also have overlapping clinical features. We discuss acute retinal pigment epitheliopathy, multiple evanescent white dot syndrome, acute posterior multifocal placoid pigment epitheliopathy, multifocal choroiditis and panuveitis, acute zonal occult outer retinopathy, birdshot chorioretinopathy, and serpiginous choroidopathy. Some of these diseases are associated with a viral prodrome suggesting a possible viral/infectious etiology, while others are associated with a number of systemic processes suggesting an autoimmune etiology.

Central Serous Retinopathy: the new carpal tunnel for information workersCentral Serous Retinopathy: the new carpal tunnel for information workers
Is Central Serous Retinopathy (CSR) the new carpal tunnel for a generation of over-stressed and over-loaded information workers who spend far too many hours per day staring at screens of varying dimensions?. Central serous retinopathy (or choroidopathy) is essentially a delamination of the retina when cellular layers that normally serve as a fluid barrier between the choroid and the retina begin to leak. This introduces a bubble or blister of fluid underneath the retina. This results in blurred and dimmed vision.. Although CSR is idiopathic, it has been linked to chronic stress, defined biochemically as elevated serum cortisol levels. This finding is corroborated by an increased incidence of CSR in those with Cushings Syndrome (chronic overexposure to elevated levels of cortisol.) Men are more often affected than women; with an age of onset between 20-50, averaging around 45.. Ive been having progressively worse vision problems since December that I had attributed to floaters or sleep ...

Hypertensive retinopathy - WikipediaHypertensive retinopathy - Wikipedia
Hypertensive retinopathy is damage to the retina and retinal circulation due to high blood pressure (i.e. hypertension). Most patients with hypertensive retinopathy have no symptoms. However, some may report decreased or blurred vision, and headaches. Signs of damage to the retina caused by hypertension include: Arteriolar changes, such as generalized arteriolar narrowing, focal arteriolar narrowing, arteriovenous nicking, changes in the arteriolar wall (arteriosclerosis) and abnormalities at points where arterioles and venules cross. Manifestations of these changes include Copper wire arterioles where the central light reflex occupies most of the width of the arteriole and Silver wire arterioles where the central light reflex occupies all of the width of the arteriole, and arterio-venular (AV) nicking or AV nipping, due to venous constriction and banking. advanced retinopathy lesions, such as microaneurysms, blot hemorrhages and/or flame hemorrhages, ischemic changes (e.g. cotton wool ...

Retinal Microvascular Signs and Functional Loss in Older Persons | StrokeRetinal Microvascular Signs and Functional Loss in Older Persons | Stroke
Quantitative retinal signs were mainly analyzed as continuous variables and qualitative retinal signs were analyzed as binary variables. The association between retinal signs and vascular risk factors was assessed using linear and logistic regression to adjust for age, gender, and race.. In the main analysis, we used linear regression to model each of the DSST score, gait speed, and square root of CES-D score as a function of a retinal sign and covariates, and we used logistic regression to model the probability of depressive mood. Standardized coefficients were computed to compare the strength of associations between retinal signs and each outcome. Depressive symptoms were analyzed in 2 different ways: (1) square root of CES-D score among participants not using antidepressant medications, because CES-D score may not accurately represent the burden of depressive symptoms in these participants; and (2) the presence of depressive mood, as defined, in all participants. Of those with data on all 5 ...

Feline Hypertensive RetinopathyFeline Hypertensive Retinopathy
Hypertensive retinopathy is a syndrome that commonly affects older cats causing an abrupt onset of bilateral blindness. This condition is often associated with a cat that suddenly begins to bump into things, appears to be lost, and displays very cautious movements. The loss of vision is associated with dilated pupils that are unresponsive or poorly responsive to incoming light. Affected eyes may appear slightly cloudy, and focal red areas may be visible thorough the pupil, as a result of retinal hemorrhage. This condition is often associated with a systemic hypertension, which is another term for high blood pressure. The retina is a thin-layered photo sensory nerve tissue, that is closely adhered to the posterior fibrous coat of the eye. When rays of light enter the eye they are focused onto the retina by the cornea and the lens. The retina then transmits a signal to the optic nerve for the brain to interpret as an image. The retina itself contains blood vessels making it vulnerable to damage ...

Retinal Vasculopathy Is Reduced by Dietary Salt RestrictionSignificance | Arteriosclerosis, Thrombosis, and Vascular BiologyRetinal Vasculopathy Is Reduced by Dietary Salt RestrictionSignificance | Arteriosclerosis, Thrombosis, and Vascular Biology
Approach and Results-Pregnant Sprague Dawley rats were fed LS (0.03% NaCl) or normal salt (0.3% NaCl) diets, and ischemic retinopathy was induced in the offspring. An LS diet reduced retinal neovascularization and vaso-obliteration, the mRNA and protein levels of the angiogenic factors, vascular endothelial growth factor, and erythropoietin. Microglia, which influence vascular remodeling in ischemic retinopathy, were reduced by LS as was tumor necrosis factor-α. Macroglial Müller cells maintain the integrity of the blood-retinal barrier, and in ischemic retinopathy, LS reduced their gliosis and also vascular leakage. In retina, LS reduced mineralocorticoid receptor, angiotensin type 1 receptor, and renin mRNA levels, whereas, as expected, plasma levels of aldosterone and renin were increased. The aldosterone/mineralocorticoid receptor-sensitive epithelial sodium channel alpha (ENaCα), which is expressed in Müller cells, was increased in ischemic retinopathy and reduced by LS. In cultured ...

NDP-related retinopathies are X-linked recessive disorders characterized by very early childhood eye diseases/disorders due to degenerative and proliferative changes of the neuroretina. The spectrum of retinal findings ranges from Norrie disease (ND) to X-linked familial exudative vitreoretinopathy (FEVR), including some cases of persistent hyperplastic primary vitreous (PHPV), Coats disease, and advanced retinopathy of prematurity (ROP). These phenotypes appear to be a continuum of retinal findings with considerable overlap. The ocular findings that permit a presumptive diagnosis of an NDP-related retinopathy include the following: Bilateral, often symmetric, involvement of the eyes Normal-sized eyes, with normal anterior chambers and usually clear lenses at birth Vitreous abnormalities (hemorrhage, membranes, detachment, and/or vitreoretinal attachments) Presence of fibrous and vascular retinal changes at birth with progressive changes through childhood or adolescence The most severe phenotype ...

Monomethyl fumarate promotes Nrf2-dependent neuroprotection in retinal ischemia-reperfusion | Journal of Neuroinflammation |...Monomethyl fumarate promotes Nrf2-dependent neuroprotection in retinal ischemia-reperfusion | Journal of Neuroinflammation |...
Retinal ischemia results in neuronal degeneration and contributes to the pathogenesis of multiple blinding diseases. Recently, the fumaric acid ester dimethyl fumarate (DMF) has been FDA-approved for the treatment of multiple sclerosis, based on its neuroprotective and anti-inflammatory effects. Its potential role as a neuroprotective agent for retinal diseases has received little attention. In addition, DMFs mode of action remains elusive, although studies have suggested nuclear factor erythroid 2-related factor 2 (Nrf2) activation as an important mechanism. Here we investigated the neuroprotective role of monomethyl fumarate (MMF), the biologically active metabolite of DMF, in retinal ischemia-reperfusion (I/R) injury, and examined the role of Nrf2 in mediating MMF action. Wild-type C57BL/6J and Nrf2 knockout (KO) mice were subjected to 90 min of retinal ischemia followed by reperfusion. Mice received daily intraperitoneal injection of MMF. Inflammatory gene expression was measured using quantitative

Long-Term Results of the Kumamoto Study on Optimal Diabetes Control in Type 2 Diabetic PatientsLong-Term Results of the Kumamoto Study on Optimal Diabetes Control in Type 2 Diabetic Patients
In the evaluation of retinal findings, the development and progression of retinopathy were defined as a change of 2 steps up or more in a modified ETDRS scale of 19 stages in the Kumamoto Study, 3 steps up or more in a ETDRS scale of 25 stages in the DCCT, and 2 steps up in a modified ETDRS scale of 21 stages in the UKPDS (2,6,9 11,16). Because the patients with preproliferative retinopathy at the initiation of the study were not included in the Kumamoto Study, this classification system of 19 stages allowed us to evaluate the retinal findings efficiently. The cumulative percentage of patients showing the worsening in retinal findings was significantly less in patients receiving intensive insulin treatment than in those receiving conventional insulin treatment. With intensive insulin therapy, the risks of retinopathy were reduced in the primary prevention, the secondary intervention, and the combined cohorts. The risk calculated by proportional-hazards analysis in the combined cohort was ...

The study shows that people with type 2 diabetes without retinopathy at the time of their first retinal examination were at low risk of progressing to preproliferative retinopathy (requiring referral to an ophthalmologist) and at very low risk of progressing to either PDR or maculopathy (requiring treatment) even after 5 years of follow-up. In contrast, patients with nonproliferative or preproliferative retinopathy at their first retinal examination were at much higher risk of progression. These findings support increasing the screening intervals in people with diabetes and without retinopathy detected at earlier screening examinations and are in keeping with our previous analysis of retinopathy prevalence at screening (5) and with other longitudinal studies of retinopathy incidence and progression (6,10-13). In this program, 80% of patients had no retinopathy at their first examination, so screening them less frequently could substantially reduce costs, allow limited resources to be shifted to ...

Retinal Disease - The Mount Sinai HospitalRetinal Disease - The Mount Sinai Hospital
The retina is the light-sensitive layer of tissue at the back of the inner eye. It acts like the film in a camera - images come through the eyes lens and are focused on the retina. The retina converts these images to electrical signals and sends them via the optic nerve to the brain, allowing us to see. Retinal diseases disrupt your retinas ability to do its job, affecting your vision.. Mount Sinai offers expertise in the diagnosis and treatment of retinal disease. Our researchers and clinicians have been engaged in the field of eye care and research since the mid-1880s. More than 18,000 people seek eye care at Mount Sinai each year.

Expression profile of FSHD supports a link between retinal vasculopathy and muscular dystrophy | NeurologyExpression profile of FSHD supports a link between retinal vasculopathy and muscular dystrophy | Neurology
We have not found evidence that deletions within the D4Z4 repeat array are associated with abnormal regulation of gene expression on chromosome 4q35. Only a single gene within 8 Mb of the D4Z4 repeat, LRP2BP, showed abnormal expression that was specific to FSHD. However, neither this gene nor FRG1 itself showed imbalance of allelic expression. Although we did observe a weak correlation between size of the residual D4Z4 array and expression level for FRG1, we did not observe upregulation of FRG1 mRNA in FSHD, assessed either by microarray analysis or qRT-PCR. In the context of recent transgenic mouse models, in which 20-fold or greater overexpression of FRG1 was required to induce skeletal myopathy,14 it is noteworthy that none of the FSHD muscle samples in the current study showed ,1.5-fold upregulation of FRG1 by microarray analysis. We also considered models involving longer range effects of the FSHD deletion on 4q gene expression, either through mislocalization of the mutant chromosome in the ...
