Macula Lutea
An oval area in the retina, 3 to 5 mm in diameter, usually located temporal to the posterior pole of the eye and slightly below the level of the optic disk. It is characterized by the presence of a yellow pigment diffusely permeating the inner layers, contains the fovea centralis in its center, and provides the best phototropic visual acuity. It is devoid of retinal blood vessels, except in its periphery, and receives nourishment from the choriocapillaris of the choroid. (From Cline et al., Dictionary of Visual Science, 4th ed)

Perifoveal vascular leakage and macular oedema after intracapsular cataract extraction. (1/755)

Perifoveal capillary leakage of fluorescein was demonstrated in 60 per cent of 50 eyes when angiography was performed two weeks after cataract extraction. Repeat angiography six weeks postoperatively in 17 eyes demonstrated persistence of already established leakage in 11 of 12 eyes and no new leakage in five eyes previously negative. Cystoid macular oedema with visual acuity of less than 20/40 six weeks postoperatively occurred in five eyes (10 per cent). Eyes of patients with vascular disease and those patients of 60 years or older were found to have altered vascular permeability significantly more frequently. Inflammation was no more severe or prevalent in those patients who demonstrated leakage and no inflammation was clinically apparent in 10 of 11 eyes demonstrating dye leakage six weeks postoperatively. We conclude that the constitutional factors of age and vascular disease are of prime importance in causing altered vascular permeability in the early postoperative period after cataract extraction; factors causing sustained leakage with reduction of visual acuity were not demonstrated.  (+info)

The use of internal limiting membrane maculorrhexis in treatment of idiopathic macular holes. (2/755)

The purpose of this study was to assess surgical results of internal limiting membrane (ILM) maculorrhexis in macular hole surgery. This study is a part of continuing prospective clinical trial of our team of researchers. Thirteen eyes of 13 patients with idiopathic macular hole underwent vitrectomy with the removal of posterior cortical vitreous, peeling of the macular ILM, and intraocular gas tamponade, followed by postoperative face-down positioning. The excised specimens were evaluated with transmission electron microscopy. Complete closure of the hole was observed in all 13 eyes (100% anatomic success rate). Visual improvement of 2 or more lines on ETDRS visual acuity chart was achieved in 11 (85%) of the 13 eyes. Six (54.5%) eyes attained visual acuity of 20/50 or better. Electron microscopy showed ILM in the removed specimens. ILM maculorrhexis is a promising new surgical approach to close idiopathic macular holes but requires further investigation and long-term evaluation.  (+info)

Quantitative assessment of macular thickness in normal subjects and patients with diabetic retinopathy by scanning retinal thickness analyser. (3/755)

AIMS: To evaluate the scanning retinal thickness analyser (RTA), a novel non-invasive imaging instrument, in diagnosing and quantitatively characterising diabetic macular oedema, and to investigate the relation between central macula thickness measured by RTA and other clinical examinations. METHODS: Central macular thickness was measured using the RTA in 40 normal subjects and 60 patients with diabetic retinopathy. The reproducibility of the retinal thickness measurements was evaluated by calculating the mean of the inter- and intrasession variations. Central macular thickness was correlated with the results of visual acuity measurements, biomicroscopy, and fluorescein angiography. RESULTS: Intra- and intersession reproducibility of the RTA in normal subjects was plus or minus 5.2% (16 microns) and plus or minus 6.1% (19 microns), respectively. The mean central macular thickness was 182 (SD 16) microns in normal subjects, 283 (116) microns in diabetic eyes without clinically significant macular oedema (CSMO), and 564 (168) microns in diabetic eyes with CSMO. Central macular thickness was significantly greater (p < 0.001) in eyes with diabetic retinopathy than in normal subjects, even when macular thickening did not meet the standard for CSMO (p = 0.019) measured by biomicroscopy. Although greater fluorescein leakage at the macula results in greater central macular thickness, only eyes with diffuse leakage had statistically significant macular thickening compared with normal subjects (p = 0.022). Central macular thickness measured with the RTA was significantly correlated with the logarithmic converted visual acuity (r2 = 0.76) in diabetic eyes. CONCLUSION: Scanning RTA, which has good reproducibility, might be useful to quantitatively detect and monitor macular thickening in diabetic retinopathy. Central macular thickness was highly correlated with logarithmic converted visual acuity in diabetic macular oedema.  (+info)

Natural history of diabetic macular streak exudates: evidence from a screening programme. (4/755)

BACKGROUND/AIMS: Diabetic retinopathy screening guidelines recommend referral to an ophthalmologist if there is exudate within one disc diameter of the fovea. Many of these patients, however, have resolution of small amounts of exudate without treatment. This study aimed to assess whether patients with minimal streak or dot exudates within one disc diameter of the fovea can be monitored in a screening programme without compromising visual acuity. METHODS: A retrospective review of records and Polaroid photographs obtained by one screening centre over a 10 year period was performed. Outcomes measured were referral rates, alteration of Snellen visual acuity, and the need for macular photocoagulation treatment. RESULTS: 55 patients (74 eyes) fulfilled entry criteria (37 streak and 37 dot exudates). Mean follow up was 56.1 months (range 12-127 months). Twenty five patients (30 eyes) were referred to an ophthalmologist. 13 eyes (17.6%) required macular photocoagulation treatment. Four eyes (5.4%) lost two or more lines of Snellen acuity over the follow up period (three from macular oedema and one from macular ischaemia). There was no relation between the presence or resolution of minimal exudate and visual loss (p>0.2). CONCLUSION: It is appropriate to monitor eyes with streak or dot macular exudates at 6-9 monthly intervals in a screening programme.  (+info)

Macular vasculopathy and its evolution in incontinentia pigmenti. (5/755)

PURPOSE: To describe macular vasculopathy in incontinentia pigmenti. METHODS: Twelve baby girls with incontinentia pigmenti were examined under general anesthesia by fluorescein angiography of the macula. Nine eyes of 9 patients had sufficient detail to allow evaluation of capillary changes. Angiography was initiated as early as 3 months of age and was repeated in 7 eyes at 3- to 12-month intervals. Changes in capillary patterns were identified. RESULTS: Irregularly enlarged or distorted foveal avascular zones were noted in all 9 maculas. Sparseness of the perifoveolar capillary bed was a characteristic finding. Sequential macular angiography demonstrated non-progressive (stable) capillary closure in 2 eyes; progressive closure in another macula; progressive closure plus addition or reopening of macular capillaries in 3 eyes; and central retinal artery occlusion, with cherry-red spot formation, in 1 eye at 12 days of age. In addition, progressive tractional detachment of the macula occurred in 2 of these eyes, and progressive macular neovascularization occurred in 1 eye. CONCLUSIONS: Macular ischemia is characteristic of incontinentia pigmenti and is often progressive. It is the initiating event of a typical vasculopathy, characterized by capillary remodelling and, occasionally, by neovascularization and tractional detachment of the retina.  (+info)

The etiology and treatment of macular detachment associated with optic nerve pits and related anomalies. (6/755)

PURPOSE: Up to two thirds of patients with optic disc pits develop a sight-limiting maculopathy. There is confusion regarding the etiology and nature of the maculopathy in these cases. We present 7 cases of serous macular detachment occurring in association with optic pits or related cavitary anomalies and identify a rhegmatogenous etiology. METHODS: We reviewed the records of 7 patients with optic nerve anomalies and macular detachment. Patients were treated with observation, barricade laser, vitrectomy, and/or gas tamponade. RESULTS: Seven patients were noted to have serous macular detachment associated with an optic nerve pit or other cavitary anomaly. A hole or tear in the diaphanous tissue overlying the optic pit was identified in all cases. None of the patients had a posterior vitreous detachment. Two were treated with photocoagulation only, and 5 underwent pars plana vitrectomy with fluid-gas exchange with or without photocoagulation. Pretreatment visual acuity ranged from 20/30 to 6/200. Posttreatment acuity ranged from 20/25 to 20/100. Five of 7 eyes had final acuities of 20/30 or better, and all treated eyes improved. CONCLUSIONS: A tear in the diaphanous tissue overlying the optic nerve pit is responsible for the development of serous macular detachment and is consistent with findings in similar conditions, such as retinal detachment in association with chorioretinal coloboma. These tears may be quite subtle, and careful biomicroscopic examination is required to appreciate them. The treatment of this condition remains controversial. However, because of the relatively poor prognosis, we believe treatment should include the formation of a barricade to fluid movement as well as sealing and relief of traction from the hole. The value of laser treatment may be increased by the early identification of a defect in the diaphanous membrane prior to the development of macular detachment. Consideration of prophylactic laser might then reduce the need for later, more invasive measures, and improve the prognosis.  (+info)

The spectral sensitivity of the human short-wavelength sensitive cones derived from thresholds and color matches. (7/755)

We used two methods to estimate short-wave (S) cone spectral sensitivity. Firstly, we measured S-cone thresholds centrally and peripherally in five trichromats, and in three blue-cone monochromats, who lack functioning middle-wave (M) and long-wave (L) cones. Secondly, we analyzed standard color-matching data. Both methods yielded equivalent results, on the basis of which we propose new S-cone spectral sensitivity functions. At short and middle-wavelengths, our measurements are consistent with the color matching data of Stiles and Burch (1955, Optica Acta, 2, 168-181; 1959, Optica Acta, 6, 1-26), and other psychophysically measured functions, such as pi 3 (Stiles, 1953, Coloquio sobre problemas opticos de la vision, 1, 65-103). At longer wavelengths, S-cone sensitivity has previously been over-estimated.  (+info)

A practical method for measuring macular pigment optical density. (8/755)

PURPOSE: Increasing evidence indicates that the macular pigments (MP) protect the central retina and may retard macular disease. For that reason, a practical method for measuring MP that does not require elaborate optics and can be applied to diverse populations by operators with a modest amount of experience was developed and validated. METHODS: A small tabletop device based on light-emitting diodes (LEDs) as the light source with electronic controls was constructed. Macular pigment was measured with the tabletop device with a 1 degrees test stimulus at 460 nm using heterochromatic flicker photometry, and the results were compared with measurements using a traditional three-channel Maxwellian view system with a xenon-arc source. RESULTS: Macular pigment density of 30 subjects (age range, 16-60 years) was measured with both stimulus systems. Macular pigment measured with the LED tabletop device in free view was highly correlated with MP measured in Maxwellian view (y = -0.03 + 1.06x, r = +0.95). The average absolute difference between the two techniques was 0.04 (SD, 0.03). The new technique was not significantly affected by variations in lens optical density, pupil size, or small head movements. CONCLUSIONS: Psychophysical measurement of MP provides a unique opportunity to make repeated noninvasive assessment of the concentration of a protective nutrient in the retina. The availability of this new device should make this measurement technology accessible to a wide variety of investigators for application to diverse populations.  (+info)

Local Variability of Macular Thickness Measurements With SD-OCT and Influencing Factors | TVST | ARVO JournalsLocal Variability of Macular Thickness Measurements With SD-OCT and Influencing Factors | TVST | ARVO Journals
Based on exploratory histograms and normal quantile plots, we posited that the variability within macular images could be divided into a random component (real measurement error), which had Gaussian distribution, and a small nonrandom component (called outliers by the M estimation method). We observed that after removal of outliers, the variability was constant across locations, eyes, and diagnostic groups, and that the upper and lower bounds of the 95% prediction limits for ME did not exceed 3 μm for any layer. This strongly suggests that macular thickness measurements can serve as valid outcomes for detection of glaucoma deterioration. The outliers had a nonrandom topographic distribution across all layers and were more frequent on the most nasal edge of the macular volume scan near the optic disc and superiorly (Fig. 4). The proportion of outliers was related to mean superpixel thickness only for mRNFL (Fig. 6); there was a direct relationship between the mRNFL thickness and proportion of ...

The etiology of these macular changes, especially the edema that resembles adult cystoid macular edema, is currently unknown. Although we did not find any neonatal risk factor(s) to be significantly distributed between the three groups, it is possible that unique comorbid factors may influence the disease pattern in our setting, which may influence structural changes in the macula, especially in the heavier infants screened in our country. This may not be applicable to other countries where these heavier infants are not at similar risk. 21,22 In the absence of any obvious causes for the macular edema, we hypothesize that this macular edema seen in eyes (29.1%) with more severe ROP could either be (1) a response to biochemical modulators, including higher concentrations of vascular endothelial growth factors (VEGFs), which could play a role in increased vascular permeability leading to retinal edema, or (2) could be caused by mechanical traction exerted on the macula.

Variation in Macular Pigment Density: Genetics and NutritionVariation in Macular Pigment Density: Genetics and Nutrition
In an earlier issue the relationship between macular pigment density, dietary carotenoids, and age-related macular degeneration (AMD) was explored. The studies summarized in that issue demonstrated the following relationships: 1) increased pigment density with increased dietary intake of lutein and zeaxanthin; 2) reduced risk of AMD with higher serum levels of the retinal carotenoids lutein and zeaxanthin; and 3) reduced risk of AMD with increased dietary intake of these carotenoids. There is evidence that increasing macular pigment MP density may help prevent AMD. There is wide inter-patient variation in macular pigment density. However, not much research has been carried out describing the variation among different groups. In a study by Hammond and colleagues (1), results indicated a higher macular pigment density among males compared with females (38% higher density) despite similar plasma levels and dietary intake of carotenoids. This is consistent with epidemiological findings that women ...

There are risks associated with this surgery. These include infection, hemorrhage, cataract, glaucoma and retinal detachment. Although many of these problems are correctable, there is a small risk that irreversible loss of vision could develop as a result of this surgery. Macular translocation surgery does not cure macular degeneration. In some cases successful closure of the CNV may only be temporary and new blood vessels will grow. If this occurs, then additional laser surgery may be necessary. In some cases, additional laser surgery may not be possible. The long-term benefit of macular translocation surgery is not known.

We studied the color-match-area effect and the Stiles-Crawford effect in 10 observers with age-related macular changes. Observers were graded on a scale of I to IV according to the Sarks classification, which correlates fundus appearance and visual acuity with the severity of postmortem histological changes in Bruchs membrane. Observers in group II showed subtle abnormalities of color matching; those in groups III and IV showed more-severe abnormalities. The Stiles-Crawford effect was abnormal in 9 of 10 eyes tested. Only one observer showed a Stiles-Crawford effect that had a well-defined peak near the center of the pupil and a near-normal bandpass. The results suggest that early age-related changes visible in the fundus can be revealed by psychophysical tests of photoreceptor architecture.. © 1988 Optical Society of America.

Lutein - NatureWordLutein - NatureWord
Lutein is a carotenoid antioxidant and essential nutrient for eye health and good vision. As a powerful antioxidant carotenoid, it reduces risks of developing cataract and helps prevent a condition called age-related macular degeneration (AMD), or loss of central vision. Macular degeneration occurs naturally as a result of old age. Nutritional deficiencies, genetics, disease and free radical damage affect eye health directly, causing damage that produces physical changes significant enough to impair normal vision. Our body does not synthesize or produce lutein itself, so we need to meet our daily requirements from dietary sources or dietary supplements.. The nutrient-pigment being physically present in the retina and macula lutea area of our eyes, good eyesight would not be possible without it. What is interesting is that getting enough lutein has been shown to lead to improve pigment density in the macula lutea area of the retina (Dietary modification of human macular pigment density).

Lutein is a naturally occurring carotenoid found in many fresh fruits and vegetables. Of the more than 600 carotenoids found in nature, lutein is one of only two carotenoids specifically located in the macula of the eye. It acts as an antioxidant to protect the eye from free radicals and supports macular pigment density. FloraGLO lutein is sourced from marigold flowers and purified from marigold flower oleoresin. It naturally contains zeaxanthin and is the worlds leading patented, purified lutein. FloraGLO lutein is used in more clinical trials than any other lutein and has been shown to support eye health and maintain healthy skin. Several studies have confirmed its effects on helping to maintain healthy visual function. Additionally, FloraGLO Lutein is the source of lutein chosen by the investigators of the AREDS2 study, sponsored by the National Eye Institute of the National Institutes of Health.

Optical Coherence Tomography Angiography retinal scans from 11 participants in the PREVENT study and associated manual segmentations of the vasculature in the scans. Optical coherence tomography angiography (OCTA) is a novel non-invasive imaging modality for the visualisation of microvasculature in vivo. OCTA has encountered broad adoption in retinal research. OCTA potential in the assessment of pathological conditions and the reproducibility of studies relies on the quality of the image analysis. However, automated segmentation of parafoveal OCTA images is still an open problem in the field.

Humans with CNGB1-related RP (12, 13, 16, 23), mice (Cngb1-X26) (27), and Cngb1-/- dogs with mutations that spare expression of the alternatively expressed GARP subunits share a similar phenotype characterized by a lack of rod-mediated retinal function from an early age, followed by a slowly progressive age-related loss of cone function and, in humans, constriction of visual fields.. Preservation of the macula is a feature of this (Figure 2) and other forms of RP. The presence of an area centralis in the dog, with its similarity to the human macula, allows the study of changes in a region of higher photoreceptor density, which is an advantage over laboratory rodents, which do not have a comparable retinal region. Like the finding of macular preservation in RP patients, Cngb1-/- dogs also showed a preserved REC+ thickness in the area centralis and visual streak (Figure 4, A and B). The packing density of photoreceptors is highest in these regions, with peak cone density in the center of the ...

Macular ischemia occurs when the small blood vessels(capillaries) close. Vision blurs because the macula no longer receives sufficient blood supply to work properly.. A medical eye examination is the only way to find changes inside your eye. If your ophthalmologist finds diabetic retinopathy, he or she may order color photographs of the retina or a special test called fluorescein angiography to find out if you need treatment. In this test a dye is injected in your arm and photos of your eye are taken to detect where fluid is leaking.. If you have diabetes, early detection of diabetic retinopathy is the best protection against loss of vision. You can significantly lower your risk of vision loss by maintaining strict control of your blood sugar and visiting your ophthalmologist regularly. People with diabetes should schedule examinations at least once a year. Pregnant women with diabetes should schedule an appointment in the first trimester because retinopathy can progress quickly during ...

Macular degeneration also referred to as ARMD is considered to be one of the most prevalent vision ailments in individuals over the age of fifty in the United States. This being said it is important to note that we require our macula to see detail and the lack of this result in not complete vision loss but distorted middle vision instead. The macula is a minute section of the retina that has the highest resolution; a feature that enables us to see great detail. Macula is a Latin word that means spot and this is the spot that we use to do most of our day to day activities that require precision, such as; reading, driving and even recognizing the faces of your loved ones. In order for you to imagine what your vision would be like without a properly functioning macula, visualize having a blank right in the middle of your eye sight but being able to see around it? How annoying is that? Therefore the loss of a properly functioning macula enables the sufferer with only peripheral vision, which is ...

MacuHealth - Frequently Asked QuestionsMacuHealth - Frequently Asked Questions
I would present improved visual performance benefits of MacuHealth as follows. A formulation containing macular pigments constituent carotenoids, (L, Z, and MZ; MacuHealth;) is required to maximally increase macular pigment and improve visual performance in a way that its competitors do not do (and this has been demonstrated in a randomized, placebo-controlled trial).. It is likely, from an evolutionary perspective, that macular pigment is there to maximize visual performance and result in visual excellence, and this intuitive reason for accumulation of these unique compounds in the central retina is borne out in the recent randomized controlled trial, which showed that supplementation with MacuHealth did indeed result in improved visual performance by maximizing vision under conditions of glare (under twilight and daytime conditions) and by maximizing contrast sensitivity (the ability to discriminate the foreground from the background). In fact, a recent publication has shown this is also true ...

Age-related macular degeneration (AMD) is a disease with multiple risk factors, many of which appear to involve oxidative stress. Macular pigment, with its antioxidant and light-screening properties, is thought to be protective against AMD. A result has been the appearance of dietary supplements containing the macular carotenoids, lutein and zeaxanthin. More recently, a supplement has been marketed containing, in addition, the third major carotenoid of the macular pigment, meso-zeaxanthin. The purpose of the study was to determine the effectiveness of such a supplement in raising macular pigment density in human subjects. A 120 day supplementation study was conducted in which 10 subjects were given gel-caps that provided 20 mg/day of predominantly meso-zeaxanthin, with smaller amounts of lutein and zeaxanthin. A second group of 9 subjects were given gel caps containing a placebo for the same 120 day period. Prior to and during the supplementation period, blood serum samples were analyzed by high

1. Showed a 30% reduced macular pigment density in eyes with AMD.. 2. Found a correlation between reduced macular pigment density and increased lens density (cataracts) in seniors; and. 3. Demonstrated that macular pigment density can be increased with dietary and/or supplemental Lutein. Maintaining sufficient levels of Lutein & Zeaxanthin (the only Carotenoid antioxidants active in the retina) can prevent ARMD and Cataracts and preserve youthful visual sensitivity.. Most individuals supplementing with sublingual Lutein and Zeaxanthin report reduced glare and visual fatigue; improved contrast sensitivity. Vinpocetine (vin-po-seh-teen) an extract from periwinkle seeds (vinca major) has been well researched and available in Europe for the past twenty years.

Most patients of established retinitis pigmentosa (RP) have subnormal peripheral vision and heavily rely on central vision for their daily activities. Central visual acuity is dependent on photoreceptor survival at the macula. Identification of structural changes that precede visual loss is essential. The aim of this study was to correlate the Spectral Domain-Optical Coherence Tomography (SD-OCT) characteristics with visual acuity in patients with typical RP. This was a retrospective, observational case series of 224 eyes of 113 RP patients conducted a tertiary eye care center. SD-OCT imaging was done for all eyes. Central retinal thickness (CRT), photoreceptor outer segment length (PROS), foveal outer segment pigment epithelial thickness (FOSPET) and ellipsoid zone (EZ) extent were measured. A new variable, FOSPET-PROS ratio (FPR), obtained by dividing FOSPET by PROS is defined and correlated to corrected distance visual acuity (CDVA) in logMAR using linear regression.

Objective. To describe the pathogenic mechanism for a central retinal detachment in eyes with a pit of the optic disc. Design. Three patients with macular detachment associated with optic nerve head pits were prospectively controlled following pars plana vitrectomy. Methods. Three cases of macular detachment associated with congenital optic nerve pit were treated with pars plana vitrectomy and air-fluid exchange and sulphur hexafloride (SF6) gas injection. During vitrectomy posterior hyaloid removal caused visible traction on the elevated retina, when the hyaloid detached. Removing the posterior hyaloid resulted in reattachment of the macular and an increase in the visual acuity without laser treatment. Conclusion. We recommend the removal of the posterior hyaloid face during pars plana vitrectomy in patients with central macular detachment associated with a pit of the optic disc.

Comparing Optical Coherence Tomography Radial and Cube Scan Patterns for Measuring Bruchs Membrane Opening Minimum Rim Width ...Comparing Optical Coherence Tomography Radial and Cube Scan Patterns for Measuring Bruchs Membrane Opening Minimum Rim Width ...
Background and Significance: Spectral Domain-Optical Coherence Tomography (OCT) is one of the most widely used imaging modality in Ophthalmology. It utilizes light waves to visualize the various layers of the retina. The OCT machines offer two different scan patterns, the circular and the cube scan patters. It is important to compare these scan pattern to see if any discrepancy exist in quantifying retinal indices. One of the newer indices is the Bruchs membrane opening minimum rim width (BMO-MRW), which is the minimum distance between from the BMO to the inner limiting membrane (ILM). The BMO-MRW is being used in the diagnosis of glaucoma. Hypothesis: To compare the cube and radial scan patterns of the SD-OCT for quantifying the BMO-MRW. We hypothesis that there might be some differences between the two scan patterns. ...

Spectral-Domain Optical Coherence Tomography (SD-OCT) is a widely used method to observe retinal layers and follow pathological events in human. Recently, this technique has been adapted for animal imaging. This non-invasive technology brings a cross-sectional visualization of the retina, which permits to observe precisely each layer. There is a clear expansion of the use of this imaging modality in rodents, thus, a precise characterization of the different outer retinal layers observed by SD-OCT is now necessary to make the most of this technology. The identification of the inner strata until the outer nuclear layer has already been clearly established, while the attribution of the layers observed by SD-OCT to the structures corresponding to photoreceptors segments and retinal pigment epithelium is much more questionable. To progress in the understanding of experimental SD-OCT imaging, we developed a method for averaging SD-OCT data to generate a mean image allowing to better delineate layers in the

N2 - Diabetic maculopathy is characterized by distortion of central vision, because of prolonged diabetic retinopathy. It may lead to permanent central vision loss when the fluid rich fat and cholesterol leaks out of damaged vessels of retina to the macula. Routine eye check up of diabetic patients can help to diagnose diabetic maculopathy at the initial stage and hence can prevent the vision loss. It is very tedious and takes a lot of time of the ophthalmologists to screen retinal images using the naked eye. Hence, a cost-effective computerized detection of diabetic maculopathy screening system can significantly assist the doctors in their diagnosis. This work proposes an automated classification of retinal fundus images into normal, NCSME (Non clinically significant macular edema) and CSME (clinically significant ...

Macular Pucker - Retinal ConsultantsMacular Pucker - Retinal Consultants
Surgery is not necessary for everyone who has a macular pucker. Eye drops, medicines, and lasers have no effect on this condition. For people who have only mildly blurred vision and are not bothered by it, no treatment is necessary. However, for those whose vision is more significantly affected, vitrectomy surgery is the only treatment that can remove a macular pucker. During this outpatient procedure, your doctor uses tiny instruments to remove the scar-tissue that is wrinkling the macula.. Usually, the macula flattens out. The symptoms slowly improve, although the vision does not always return to normal. Typically, patients can expect two or more lines of improvement on the eye chart, however cataracts (clouding of the natural lens in the eye) may develop or progress more rapidly after surgery to fix the macular pucker. Cataract surgery may be necessary to obtain the best vision after macular pucker surgery.. ...

PURPOSE: Choroideremia is a rare degenerative retinal disease that causes incurable blindness. It occurs as a result of the deficiency of the X-linked CHM gene, which encodes the Rab escort protein 1 (REP1). Gene therapy has been developed to treat CHM using adeno-associated viral vectors and is currently undergoing clinical trials. Expression of the CHM gene is ubiquitous throughout the retina, and it is therefore important to identify which retinal layers are affected in the disease process. The purpose of this study was to assess in particular the choriocapillaris using optical coherence tomography angiography because this layer is difficult to see with conventional imaging techniques. METHODS: Six men with choroideremia were identified and underwent standardized optical coherence tomography angiography as part of an ethics-approved clinical study and were compared with age-matched control subjects. RESULTS: The choriocapillaris appeared normal in regions where the retinal pigment epithelium remained

What Is Diabetic Retinopathy?What Is Diabetic Retinopathy?
With NPDR, tiny blood vessels leak, making the retina swell. When the macula swells, it is called macular edema.. This is the most common reason why people with diabetes lose their vision. Also with NPDR, blood vessels in the retina can close off. This is called macular ischemia. When that happens, blood cannot reach the macula. Sometimes tiny particles called exudates can form in the retina. These can affect your vision too. If you have NPDR, your vision will be blurry.. PDR (proliferative diabetic retinopathy). PDR is the more advanced stage of diabetic eye disease. It happens when the retina starts growing new blood vessels. This is called neovascularization. These fragile new vessels often bleed into the vitreous. If they only bleed a little, you might see a few dark floaters. If they bleed a lot, it might block all vision ...

Two galvo scanners with different pivot-offset distances in the reference arms are used for spatial frequency modulation and multiplexing. While simultaneously driving the galvo scanners in the reference arms and the sample arm, the spatial spectrum of the acquired two-dimensional OCT spectral interferogram corresponding to the shallow and deep depth of the sample will be shifted to the different frequency bands in the spatial frequency domain. After data filtering, image reconstruction and fusion the spatial frequency multiplexing SDOCT system can provide an approximately 1.9 fold increase in the effective ranging depth compared with that of a conventional single-reference-arm full-range SDOCT system ...

The most important advantage of FA about fundus photography is its capacity to detect macular ischemia denoted by nonperfusion in the retinal capillaries also to detect subtle DME as evidenced by fluorescein leakage with the capillaries (fifty five). An automatic approach to quantitating microaneurysms from digitized fluorescein angiograms was shown to reliably detect microaneurysms with a sensitivity of eighty two% (fifty six). Even further advancement and automation could boost the utility and accessibility of FA ...

STROOM - Forced ExposureSTROOM - Forced Exposure
48 Cameras was the brainchild and life project of self-proclaimed non-musician Jean-Marie Mathoul, a social worker born and raised in Huy who carefully conducted 48C towards cult status. The name of the collective references photographer Eadweard Muybridge and a poem by Jim Morrison; "Muybridge derived his animal subjects from the Philadelphia Zoological Garden, male performers from the University. The women were professional artists models, also actresses and dancers, parading nude before the 48 cameras". It is important to note that 48C is somewhat of a non-band. The musicians and collaborators never actually recorded together, and to this day some havent even met each other. Before starting the recording process, J-M built an album in his mind: choice of album and song titles, who was to collaborate, even the artwork was clear long before the first note was played, leaving little room for surprises. Throughout the years, collaborators sent their parts by snail mail on tape, DAT, or even ...
