To describe a wide array of peripheral vascular changes using fluorescein angiography in preterm neonates, without high risk characteristics for developing retinopathy of prematurity, that were exposed to high oxygen concentration. Retrospective, two center, case series. Newborns at two different hospitals with ≥1500 g or gestational age of ≥32 weeks, fluorescein angiography performed, and with high oxygen exposure without adequate control were included. 294 infants diagnosed with ROP were analyzed. Only 28 eyes from 14 patients with peripheral vascular abnormalities in older and heavier babies were included. Two distinct type of peripheral vascular changes were observed: group 1 or non-proliferative: areas of capillary non-perfusion along with widespread arteriovenous shunting between adjacent primary vessels, tortuosity of primary vessels, abnormal budding of tertiary vessels and capillaries, abnormal capillary tufts and absence of foveal avascular zone; group 2 or proliferative: all of the

PURPOSE: To provide long-term (| or =5 years) follow-up data on patients who had previously undergone macular retinal pigment epithelium (RPE) translocation surgery for choroidal new vessels (CNVs) associated with age-related macular degeneration. DESIGN: Retrospective interventional case series. PARTICIPANTS: Four of 9 patients who originally underwent surgery and whose results were reported after 2 years of follow-up were reviewed again 5 to 6 years after surgery. METHODS: All surviving patients from the original trial were contacted, and those who consented to full ocular examination were called in for review. Examination included best-corrected visual acuity (VA), optical coherence tomography (OCT), fundus autofluorescence, fluorescein angiography (FA), and indocyanine green angiography. MAIN OUTCOME MEASURES: Long-term success of RPE translocation was assessed by VA, imaging, angiography, and maintenance of overlying foveal fixation. Comparisons were made to the original 2-year follow-up data
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 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 ...
Since its introduction in the early 1960s, fluorescein angiography has proved to be an essential tool for diagnosis of many retinal disorders. This course will provide an overview of the use of fluorescein for diagnosing eye related diseases and conditions and include appropriate doses for adult and pediatric patients. Awareness of the side effects, adverse reactions, and complications of the contrast agent allow the ophthalmic healthcare team to anticipate, respond quickly, and support the patient before, during, and following the angiographic procedure using fluorescein ...
Fluorescein Angiography (FA) is an investigation to further investigate the cause of the retinal disease. In this 3ml of a water soluble fluorescent dye is injected into a vein on the patients arm. As the dye reaches the blood vessels of the retina ( It takes only 10sec !! ) , sequential photographs are taken using a sophisticated digital camera. The abnormal leakage of dye or absence of normal pattern of dye gives the doctor clues regarding the diagnosis and severity of the retinal disease ...

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 ...

A macular indentor for positioning over a macular area of an eye comprises a strip of material having a pair of opposed ends, the strip having a raised portion for indenting the macular area of the eye. The macular indentor is also inflatable for selectively applying pressure to the macular area of the eye.
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. ICG angiography is also performed with a digital (computerized) system at Retina Care Specialists, allowing for immediate interpretation by the physician.. ...
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 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 ...
I am a 40 years old man suffered from choroidal neovascular membrane (CNVM) 2 years back in the right eye. I took Avastin at that time.

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 ...

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 ...

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 ...

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 ...
Three patients with BVMD were evaluated. The first patient had macular lesions at the pseudohypopyon and vitelliruptive stages with BCVA values of 10/10 and 20/32, respectively. The second patient had a BCVA of 20/60 in the left eye and 20/25 in the right eye. Dilated fundoscopy revealed that the left eye had developed choroidal neovascularization. A macular lesion at the vitelliform stage was observed in the right eye. The last patient had pigmentary macular changes consistent with a diagnosis of BVMD. In both eyes, BCVA was 10/10. OCT-A revealed a bridging vessel in the foveal avascular zone in five eyes and a dense subretinal capillary network in one eye with choroidal neovascularization ...
