Vertebrobasilar Insufficiency
Localized or diffuse reduction in blood flow through the vertebrobasilar arterial system, which supplies the BRAIN STEM; CEREBELLUM; OCCIPITAL LOBE; medial TEMPORAL LOBE; and THALAMUS. Characteristic clinical features include SYNCOPE; lightheadedness; visual disturbances; and VERTIGO. BRAIN STEM INFARCTIONS or other BRAIN INFARCTION may be associated.
Carotid Stenosis
Narrowing or stricture of any part of the CAROTID ARTERIES, most often due to atherosclerotic plaque formation. Ulcerations may form in atherosclerotic plaques and induce THROMBUS formation. Platelet or cholesterol emboli may arise from stenotic carotid lesions and induce a TRANSIENT ISCHEMIC ATTACK; CEREBROVASCULAR ACCIDENT; or temporary blindness (AMAUROSIS FUGAX). (From Adams et al., Principles of Neurology, 6th ed, pp 822-3)
Intraocular Pressure
The pressure of the fluids in the eye.
Dry Eye Syndromes
Corneal and conjunctival dryness due to deficient tear production, predominantly in menopausal and post-menopausal women. Filamentary keratitis or erosion of the conjunctival and corneal epithelium may be caused by these disorders. Sensation of the presence of a foreign body in the eye and burning of the eyes may occur.
Radiographic Image Enhancement
Improvement in the quality of an x-ray image by use of an intensifying screen, tube, or filter and by optimum exposure techniques. Digital processing methods are often employed.
Arteriovenous Fistula
An abnormal direct communication between an artery and a vein without passing through the CAPILLARIES. An A-V fistula usually leads to the formation of a dilated sac-like connection, arteriovenous aneurysm. The locations and size of the shunts determine the degree of effects on the cardiovascular functions such as BLOOD PRESSURE and HEART RATE.
Retinal Cone Photoreceptor Cells
Photosensitive afferent neurons located primarily within the FOVEA CENTRALIS of the MACULA LUTEA. There are three major types of cone cells (red, blue, and green) whose photopigments have different spectral sensitivity curves. Retinal cone cells operate in daylight vision (at photopic intensities) providing color recognition and central visual acuity.
Extravasation of Diagnostic and Therapeutic Materials
The escape of diagnostic or therapeutic material from the vessel into which it is introduced into the surrounding tissue or body cavity.
Ultrasonography, Interventional
The use of ultrasound to guide minimally invasive surgical procedures such as needle ASPIRATION BIOPSY; DRAINAGE; etc. Its widest application is intravascular ultrasound imaging but it is useful also in urology and intra-abdominal conditions.
Pedigree
The record of descent or ancestry, particularly of a particular condition or trait, indicating individual family members, their relationships, and their status with respect to the trait or condition.
Cerebral Arteries
The arterial blood vessels supplying the CEREBRUM.

Variations in acute multifocal histoplasmic choroiditis in the primate. (1/1800)

Experimental histoplasmic choroiditis was produced in primates by intracarotid injections of living H. capsulatum organisms. The severity of the choroiditis varied with inoculum size, as well as with site of injection (common carotid vs. internal carotid artery). A reproducible model of histoplasmic choroiditis in primates was produced with an internal carotid injection of 5,000 to 10,000 organisms/lb. The clinical and histopathological course of this acute choroiditis over the first 30 days is presented.  (+info)

Pigment epithelial windows and drusen: an animal model. (2/1800)

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)

In vivo significance of ICAM-1--dependent leukocyte adhesion in early corneal angiogenesis. (3/1800)

PURPOSE: Numerous investigations have stressed the significance of leukocytes in early angiogenesis. Leukocytes invade the cornea, and the location of their extravasation corresponds to the site of vessel ingrowth. The interactions between leukocytes and vascular endothelium are mediated by various proteins, including adhesion molecules such as intercellular adhesion molecule-1 (ICAM-1). In this study, the role of ICAM-1 during early corneal angiogenesis was evaluated in vivo. METHODS: Corneal neovascularization was induced in New Zealand White rabbits by use of intrastromal pellets containing 750 ng vascular endothelial growth factor (VEGF). The fluorescent dye rhodamine 6G was used to stain leukocytes in vivo. Leukocyte adhesion and vessel growth were quantified in vivo by high-resolution fluorescence angiography. To inhibit ICAM-1 interactions a microemulsion containing anti-ICAM-1 antibody was applied topically. RESULTS: Limbal vessels showed increased leukocyte adhesion 24 hours after pellet implantation: The number of rolling and sticking leukocytes was significantly increased compared with the number in control animals (P < 0.01). Treatment with anti-ICAM-1 antibody resulted in reduced leukocyte sticking and increased leukocyte rolling. The area covered by new blood vessels was significantly diminished in eyes treated with anti-ICAM-1 (P < 0.05). CONCLUSIONS: The results support the hypothesis that ICAM-1-mediated leukocyte adhesion is a key event in early angiogenesis. This model may serve for investigation of the significance of adhesion molecules by in vivo observation and quantification.  (+info)

Metabolic acidosis-induced retinopathy in the neonatal rat. (4/1800)

PURPOSE: Carbon dioxide (CO2)-induced retinopathy (CDIR) in the neonatal rat, analogous to human retinopathy of prematurity (ROP), was previously described by our group. In this model, it is possible that CO2-associated acidosis provides a biochemical mechanism for CDIR. Therefore, the effect of pure metabolic acidosis on the developing retinal vasculature of the neonatal rat was investigated. METHODS: A preliminary study of arterial blood pH was performed to confirm acidosis in our model. In neonatal rats with preplaced left carotid artery catheters, acute blood gas samples were taken 1 to 24 hours after gavage with either NH4Cl 1 millimole/100 g body weight or saline. In the subsequent formal retinopathy study, 150 newborn Sprague-Dawley rats were raised in litters of 25 and randomly assigned to be gavaged twice daily with either NH4Cl 1 millimole/100 g body weight (n = 75) or saline (n = 75) from day 2 to day 7. After 5 days of recovery, rats were killed, and retinal vasculature was assessed using fluorescein perfusion and ADPase staining techniques. RESULTS: In the preliminary pH study, the minimum pH after NH4Cl gavage was 7.10+/-0.10 at 3 hours (versus 7.37+/-0.03 in controls, mean +/- SD, P < 0.01). In the formal retinopathy study, preretinal neovascularization occurred in 36% of acidotic rats versus 5% of controls (P < 0.001). Acidotic rats showed growth retardation (final weight 16.5+/-3.0 g versus 20.2+/-2.6 g, P < 0.001). The ratio of vascularized to total retinal area was smaller in acidotic rats (94%+/-4% versus 96%+/-2%, P < 0.001). CONCLUSIONS: Metabolic acidosis alone induces neovascularization similar to ROP in the neonatal rat. This suggests a possible biochemical mechanism by which high levels of CO2 induce neovascularization and supports the suggestion that acidosis may be an independent risk factor for ROP.  (+info)

Idiopathic central serous chorioretinopathy. (5/1800)

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)

Chronic retinal vein occlusion in glaucoma. (6/1800)

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)

De novo lesions in presumed ocular histoplasmosis-like syndrome. (7/1800)

Two patients with multifocal choroiditis similar or identical to POHS are presented. Colour photographs and fluorescein angiography document the occurrence of de novo lesions in the originally involved eye. The cases also demonstrate the development of new choroidal lesions within the originally involved eye, the early evolution of the "basic choroidal lesion", and the need for fluorescein angiography for visualizing the underlying choroidal lesion.  (+info)

The use of internal limiting membrane maculorrhexis in treatment of idiopathic macular holes. (8/1800)

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)

Purpose : Age-Related Macular Degenration (AMD) is the leading cause of blindness in Europe, the USA and Australia. This study tested the hypothesis the hypothesis that targeting MFAP4 (which is upregulated at sites of vascular remodelling) would reduce choroidal vessel growth following laser induced choroidal neovascularisation in murine eyes. Methods : Female C57/Bl6 mice were anaesthetised and laser coagulation of the Bruchs membrane was performed (Phoenix Micron IV retinal imaging microscope). Intraocular injection of either 1mg mouse IgG (DAKO) 1 or 5mg aMFAP4 or 1mg aVEGF. Injections were performed using a 36 Gauge Hamilton syringe, in a total of 2ml. Injections were performed at day 0 and day 7. Fundus Fluorescein Angiography (FFA) was performed on day 7 and day 14. Mice were culled and eyes excised, fixed in 4% paraformaldehyde.

Fluorescein Angiography (FA)Fluorescein Angiography (FA)
In order to find abnormal blood vessels under the retina and/or to identify conditions that can cause retinal swelling and reduced vision, it is sometimes necessary to perform a test called angiography.. This test is performed by injecting a dye into the vein of the arm, then photographing the dye as it passes through the circulation in the back of the eye. Depending on the pattern of dye transmission and leakage, certain disease processes can be identified. Two different dyes are commonly used: fluorescein and indocyanine green. Special digital cameras joined to computers are used to maximize the effectiveness of this test.. Doctors choose fluorescein angiography to study diseases of the retinal and choroidal blood vessels within the eye. The results of this test enable the physician to diagnosis many abnormalities of the retina and choroid that could not be diagnosed accurately otherwise. The results of this study also serve as a guide to laser treatment for many diseases of the retina and ...

Eales disease - WikipediaEales disease - Wikipedia
Eales disease is a type of obliterative vasculopathy, also known as angiopathia retinae juvenilis, periphlebitis retinae, primary perivasculitis of the retina, is an ocular disease characterized by inflammation and possible blockage of retinal blood vessels, abnormal growth of new blood vessels (neovascularization), and recurrent retinal and vitreal hemorrhages. Eales disease with a characteristic clinical picture, fluorescein angiographic finding, and natural course is considered a specific disease entity. Patients are often asymptomatic in the initial stages of retinal perivasculitis. Some patients may develop symptoms such as floaters, blurring vision, or even gross diminution of vision due to massive vitreous hemorrhage. Vision in these patients can be normal to hand movements or light perception only. Bilaterality is quite common (50-90%) patients. The cause of this condition is not known. However, in a significant number of patients, DNA of the bacterium Mycobacterium tuberculosis was ...

The patients visual acuities were 20/100 with -2.00 spherical diopters (D) in the right eye and 20/80 with -2.50 spherical D in the left eye. While the anterior segment examinations were unremarkable for both eyes, the fundus examination of the patient demonstrated multiple bilateral, sharply defined, and scalloped chorioretinal atrophy areas in the mid-peripheral zones. Fundus fluorescein angiography did not show any leakage even in late phases for both eyes. The wide-field OCT scans of both eyes disclosed that increased central macular thicknesses with widespread hyporeflective spaces separated by multiple linear bridging elements in inner nuclear and inner plexiform layers in addition to retinal defects at outer nuclear and outer plexiform layers. Moreover, elevated level of plasma ornithine (967 Mmol/L) was detected, establishing the diagnosis of GA. Additionally, ocular examinations revealed no specific findings such as optic pits, myopic degeneration with staphyloma, or vitreoretinal ...

PEDs occur when the thickened inner aspect of the Bruchs membrane and the RPE detach from the rest of the membrane. PEDs can be drusenoid, serous, fibrovascular, or hemorrhagic. Drusenoid PEDs are not associated with CNV; however, in the AREDS, eyes with drusenoid PEDs had a 42% chance of progressing to advanced AMD at 5 years, with an even split between foveal GA and CNV.¹²⁻¹⁴ Fibrovascular and hemorrhagic PEDs are associated with CNV, as may serous PEDs. Clinical signs suggesting CNV associated with a PED include subretinal fluid, lipid, blood, and chorioretinal folds.¹⁶ Intravenous fluorescein angiography (IVFA) or optical coherence tomography angiography (OCT-A) can differentiate the types of PED and whether CNV is present.. Retinal angiomatous proliferation is a form of CNV that is believed to arise from within the retina. The retinal vessels are seen to be anastomosing with the neovascular membrane. It is uncertain whether these vessels develop prior to or after CNV. On OCT, the ...

Phase-variance optical coherence tomography (pv-OCT) visualizes retinal vasculature non-invasively and thus has potential in the early diagnosis of retinal vascular diseases that include diabetic retinopathy and macular degeneration. Currently, circulation of the retina in clinical settings makes use of fundus fluorescein angiography (FA), which involves injection of a fluorescein dye to view the perfusion into the blood stream. The injection makes this an invasive procedure with complications like nausea and vomiting to anaphylaxis and limited axial resolution and information regarding structural and functional consequences of vascular disease. These factors necessitate the development of a non-invasive optical tool for early diagnosis of retinal vascular diseases. The project concentrates on the clinical development of pv-OCT, which has the advantage of being a non-invasive, three-dimensional microvascular imaging method. Developing image processing algorithms for feature extraction and noise ...

AngiographyAngiography
This test is similar to fluorescein angiography in that a dye is injected into the vein in the arm and we take photographs over time to help us diagnose problems in the back of the eye. The difference, however, is that the dye is used to study mainly the choroidal circulation, or the layer of blood vessels underneath the retina. ICG angiography is used less frequently than fluorescein angiography, but it can be especially useful in cases where blood obscures visualization of the retina.

Your doctor may ask you not to eat the morning of your angiography. Your testing will most likely be performed in a specially equipped examination room. It does not require a surgery center or anesthesia. Prior to your procedure, your eye will be dilated.. During the test, a harmless orange-red dye called Fluorescein will be injected into a vein in your arm. The dye will travel through your body to the blood vessels in your retina. Your doctor will use a special camera with a green filter to flash a blue light into your eye and take multiple photographs. He will analyze the pictures and identify any damage to the lining of the retina or to spot the growth of new blood vessels.. This diagnostic test takes about 30 minutes to an hour, including the time for dilation of your eye. You can go home immediately after the procedure. After your angiography, your skin and urine may appear discolored for a short time until the Fluorescein is completely out of your system.. ...

The retina is complex and is composed of nerve layers and blood vessels as well as other tissues. The blood vessels that are located in the retina are able to be examined using a special technique and camera called Intravenous Fluorescein Angiography (IVFA). In this procedure, the eye is dilated, and a special dye is injected into the arm. Within 10-15 seconds, the dye that was injected into the arm passes through the blood vessels located in the back of the eye. When the progression of dye occurs, photographs are taken. The filling of the blood vessels with as well as the clearing of the dye allows the physician to see what parts of the eye are healthy or unhealthy. This information allows the physician to target treatment to the most affected part of the eye ...

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 ...

Inhibition of Experimental Choroidal Neovascularization by a Novel Peptide Derived from Calreticulin Anti-Angiogenic Domain[v2]...Inhibition of Experimental Choroidal Neovascularization by a Novel Peptide Derived from Calreticulin Anti-Angiogenic Domain[v2]...
Choroidal neovascularization (CNV) is a key pathological feature of several of the leading causes of vision loss including neovascular age-related macular degeneration. Here we show that a calreticulin anti-angiogenic domain (CAD)-like peptide 27, CAD27, inhibited in vitro angiogenic activities, including tube formation and migration of endothelial cells, and suppressed vascular sprouting from rat aortic ring explants. In rat model of laser-induced CNV, we demonstrate that intravitreal injection of CAD27 significantly attenuated the formation of CNV lesions as measured via fundus fluorescein angiography and choroid flat-mounts (19.5% and 22.4% reductions at 10μg and 20μg of CAD27 injected, respectively). Similarly, the reduction of CNV lesions was observed in the groups of rats that had received topical applications of CAD27 (choroid flat-mounts: 17.9% and 32.5% reductions at 10μg/mL and 20μg/mL of CAD27 installed, respectively). Retinal function was unaffected, as measured using

Fluorescein angiography (FA) has long been the gold standard for vascular imaging of the retina and choroid. It is a test that involves the intravenous injection of fluorescein dye, followed by imaging of the dyes passage through the blood vessels inside the eye. It is commonly used to diagnose many forms of retinovascular disease, as well as to assess the retinas response to various therapeutic interventions. While FA is a relatively safe diagnostic test, it carries the risk of both minor and major side effects. These include nausea and vomiting, yellowing of the skin and urine, vascular extravasation with skin eruption and necrosis, vasovagal reactions, myocardial infarction, respiratory failure, anaphylaxis, cardiopulmonary arrest, and death. Additionally, the test is time-consuming, technically difficult to perform, and requires patients to undergo the discomfort associated with intravenous access. Despite these drawbacks, FA is still commonly used in clinical practice, as there are no ...

Purpose: Retinopathy of prematurity (ROP) is the leading cause of preventable blindness in premature infants. Antivascular endothelial growth factor (anti-VEGF) therapy has been used increasingly in treatment as a pharmacological alternative to laser therapy. In this study, we evaluate the results of low-dose anti-VEGF treatments. Methods: Design: Retrospective--observational study. Infants who had been evaluated for ROP disease between February 2016 and February 2017 were assessed. We retrospectively reviewed the ROP stages, treatment results, and complications. Laser photocoagulation (LPC) and intravitreal bevacizumab (0.16 mg IVB) were used for treatment and fundus fluorescein angiography (FFA) was also performed in some of the cases. Results: IVB was applied to 43 infants. A macular hole was seen in one infants eye after IVB. LPC was applied to avascular areas in 21 infants. In three patients, persistence of the disease was observed after administration of a low dose of IVB. Additional LFK ...

Bevacizumab is a recombinant humanized monoclonal antibody against VEGF. It has been approved by the FDA for the treatment of metastatic colon cancer 18. We hypothesize that VEGF also plays a role in the development of CNV in pathologic myopia. Therefore, employing a mode of therapy that would decrease the risks posed to eyes with attenuated sclera, we have treated, through special approval by the Pharmacy and Therapeutic Committee of the Johns Hopkins University School of Medicine, two patients with persistent myopic CNV with intravenous bevacizumab 19. Despite multiple treatments with PDT, the CNV remained active and vision continued to decline in these two index patients. After four infusions of bevacizumab, the CNV became inactive. Six months after the last infusion in each patient, the CNV showed no evidence of activity or leakage on fluorescein angiography. Vision also improved in the diseased eyes of both patients. The two patients tolerated the infusions well, with no adverse events ...

Identifying the factors for improving quality of oral fluorescein angiographyIdentifying the factors for improving quality of oral fluorescein angiography
Aim To evaluate the quality of oral fluorescein angiography (FA) in relation to food intake. Methods This is an observational, case-crossover study. We collected information from patients undergoing routine oral FA for retinal disease at the Shiley Eye Institute. Eighty patients (160 eyes) were analysed. Fasting and non-fasting images of the same patient were recorded, compared and analysed for different image quality parameters and clinical relevance by experienced retina specialists. Results When analysing the images, intergrader agreement was moderate to good with a Kappa averaging 0.60 (0.5-0.85). When patients were fasting pre-imaging, better angiography quality scores were achieved when compared with images taken when patients were non-fasting (mean 0.84 vs 0.72, p less than 0.001). Multivariate analysis showed that non-fasting patients with higher body mass index had the worst scores.

PURPOSE: To locate the mildest and/or earliest changes in the retina and/or choroid in Sveinsson chorioretinal atrophy (SCRA), using more advanced techniques than previous studies. METHODS: We used fundus photography, intravenous fluorescein angiography (IVFA) enhanced ocular coherence tomography (OCT) scans, microperimetry and multifocal electroretinography (mfERG) in an attempt to locate the mildest changes in SCRA. Eight patients with SCRA were examined. To improve the resolution of OCT scans, several consecutive recorded B-scans were retrieved for each location of interest. The scans were processed off-line with an averaging algorithm developed to maximally reduce laser speckle (noise). Static microperimetry was performed using the Rodenstock scanning laser ophthalmoscope (SLO). RESULTS: Biomicroscopy and fundus photographs disclosed an apparent thinning of the retinal pigment epithelium (RPE) in the areas minimally affected, where possible changes in the transparent sensory retina were not ...

How do I know if I have Diabetic Retinopathy ?. Prevention is always better than cure. Hence it is essential to have periodic evaluation of your eye by an Ophthalmologist to detect the condition early..Your pupils may be dilated with eyedrops, so that the Ophthalmologist may have a good look at the back of the eye. Newer modalities of investigations like Fundus Fluorescein Angiography (FFA) and Optical Coherence Tomography (OCT) help in accurately determining the severity of the disease and its treatment.. How is Diabetic Retinopathy treated?. Treatment depends on the stage and severity of the disease. Hence early detection of Diabetic Retinopathy is very important. Every Diabetic patient should undergo a proper retina examination at regular intervals. Several treatment options are available for the management of Diabetic Retinopathy like Laser Application to the retina (Laser PRP), certain drugs called Anti VEGFs to be injected into the eye or Vireo-Retinal Eye Surgery in advanced cases. ...

Background Diabetic macular edema (DME) is the most common cause of loss of vision in diabetic patients. The role of inflammation in the pathogenesis of DME has been demonstrated. An intravitreal (IVT) injection of triamcinolone acetonide (TA) is a treatment option for DME. The high incidence of side effects, however, limits the routine use of IVT TA. Aim The aim of this study was to compare the efficacy and safety of an IVT injection of TA with the less invasive posterior subtenon (PST) injection of TA. We test the hypothesis that both techniques have equal efficacy and safety. Patients and methods This is prospective randomized noninferiority trial. Totally, 34 eyes from 30 patients with diffuse center involving DME were randomized in a 1: 1 ratio to receive a TA injection by either method. Baseline evaluation included measurement of best-corrected visual acuity (BCVA) and intraocular pressure (IOP), fundus fluorescein angiography, and optical coherence tomography to measure central macular ...

The understanding of retinal disease has evolved rapidly with a growing number of clinical evidence supplied by ultrawidefield retinal imaging. Optos 200Tx ultra-widefield retinal imaging system uses a scanning laser ophthalmoscope, as well as an ellipsoid mirror. This creates a possibility of making a virtual focal point inside the eye and, in turn, enables the system to simultaneously make a single capture of the central retina and periphery. This system offers multimodal ultra-widefield imaging, including color photographs, fundus autofluorescence images, red-free images and fluorescein angiography (FA), allowing visualization of the retinal circulation. For color photographs, green and red lasers are used simultaneously to allow visualization of retinal substructures from the sensory retina and retinal pigment epithelium to the choroid. In our clinic ultra-widefield fluorescein angiography has became an elegant diagnostic imaging modality that has improved our ability to diagnose and plan ...

Processing Equipment - Ophthalmic Photographers SocietyProcessing Equipment - Ophthalmic Photographers Society
An Ocular fluorescein angiogram is often referred to in ophthalmology circles as either an angiogram or a fluorescein. We will use the term angiogram to mean Ocular Fluorescein Angiogram. Other types of angiography require methods and procedures which differ from those outlined here. Although digital imaging is quickly becoming the standard method for acquiring and presenting angiographic images, black and white film processing and printing remain an integral part of ophthalmic photography in some areas. The film on which angiograms are taken must be processed using a photographic developer. This developer creates a negative image on the film. The fluorescein dye, which appears light in the vessels of the ocular fundus, are rendered as dark images on the film against a clear background.. Many ophthalmologists prefer to interpret the fluorescein negatives because some small amount of information may be lost in producing prints, and because simple film processing can be done fairly quickly without ...
