Purpose: : To evaluate the effect of topically administered diclofenac, ketorolac, and etanercept on experimental corneal neovascularization. Methods: : Chemical cauterization of the cornea in 32 eyes of 32 rats was performed using silver nitrate sticks to induce corneal neovascularization. Topical instillation of diclofenac (Volteran, Novartis Pharmaceuticals), ketorolac (Acular, Allergan), and etanercept (Enbrel, Immunex Corp.) was compared to normal saline treatment for inhibition of neovascularization for 7 days. All animals were treated in accordance with the ARVO guidelines on the care and use of animals in research. The animals were randomly divided in 4 groups. Group 1 (n=8) received balanced salt solution (control), group 2 (n=8) received ketorolac 0.5 %, group 3 (n=8) received diclofenac 0.1%, and group 4 (n=8) received 200 µg/ml of etanercept. Percentage area of cornea covered by neovascularization and scar in each group was calculated separately by use of computer software on ...
The purpose of the study is to test the investigational drug Gamunex-C on the growth of blood vessels over the cornea. This study is being conducted by Dr. Balamurali Ambati at the Moran Eye Center at the University of Utah.. The cornea is the clear outer front part of the eye. In corneal neovascularization, blood vessels grow over the cornea. Corneal neovascularization and ocular anterior segment inflammations are sight-threatening conditions. Lipid deposition and edema with subsequent scar formation can compromise corneal clarity irreversibly. Corneal neovascularization is also a well recognized risk factor for corneal graft failure. In its natural state, the cornea is a site of immune privilege well suited to tissue transplantation. Once vascularized, there is direct exposure of corneal antigens to circulating host immune mechanisms greatly increasing the chance of rejection [Collaborative Corneal Transplantation Study].. Melting or inflammation in the anterior chamber, cornea, or ocular ...
Corneal neovascularization (CNV) is the in-growth of new blood vessels from the pericorneal plexus into avascular corneal tissue as a result of oxygen deprivation. Maintaining avascularity of the corneal stroma is an important aspect of corneal pathophysiology as it is required for corneal transparency and optimal vision. A decrease in corneal transparency causes visual acuity deterioration. Corneal tissue is avascular in nature and the presence of vascularization, which can be deep or superficial, is always pathologically related. Corneal neovascularization is a sight-threatening condition that can be caused by inflammation related to infection, chemical injury, autoimmune conditions, post-corneal transplantation, and traumatic conditions among other ocular pathologies. Common causes of CNV within the cornea include trachoma, corneal ulcers, phylctenular keratoconjunctivitis, rosacea keratitis, interstitial keratitis, sclerosing keratitis, chemical burns, and wearing contact lenses for ...
Pathologic angiogenesis is involved in cancer and several blinding conditions such as wet age-related macular degeneration, proliferative retinopathies and corneal neovascularization.. In these dieseases, the angiogenic triggers are hypoxia and inflammation, and both involve the main angiogenic mediator, which is Vascular Endothelial Growth Factor (VEGF). Among available treatments, anti-VEGF often shows limited or temporary efficacy, while steroids are potentially responsible for many side-effects. This thesis presents a series of linked studies aimed at elucidating the early pathologic changes leading to inflammation and corneal neovascularization, and how various treatments affect this process. In this thesis, anti-inflammatory and anti-angiogenic treatments are applied in corneal neovascularization models, to identify VEGF-independent pathways and other novel factors as future therapy targets, as well as to investigate the endogenous modulation of angiogenesis.. A model of experimental ...
Corneal Neovascularization (CNV), the extensive growth of blood vessels from conjunctiva into the cornea. It is a sight-threatening condition that can decreases eyesight and even leads to blindness. The pathologic growth of blood vessels impairs light transmission, promotes scar formation and causes inflammations, which harm visual acuity. Abnormal angiogenesis plays an important role in the process of CNV, which may result from corneal wound healing. Neovascular eye disease is one of the most common eye diseases in clinical admissions. CNV blinds approximately 7 million people worldwide. Continued mechanistic studies are a key to the prevention and treatment of CNV. Research in CNV animal models is essential in eye diseases. Several main methods of CNV models preparation are summarized in this review.. ...
Due to its noninvasive accessibility and clarity, cornea serves an ideal target for evaluating the efficacy of various treatments against corneal disorders. A multitude of potential gene therapies based on different genes and strategies have been tried in the context of corneal diseases, including corneal NV. For example, various viral-mediated gene delivery systems have been proposed to produce expression of the desired genes with varying expression levels and duration [32-34]. In the case of gene therapy for corneal NV, as in many other situations, it is well recognized that targeting a single gene often fails to ensure the theoretically predicted efficacy [23,35-37]. We therefore investigated the possibility of better management of corneal NV by combining different anti-angiogenic factors in the present study. We showed that the combination of two or three genes exhibited additive effects over a single gene in inhibiting HUVEC proliferation in vitro (Figure 1A). This additive effect, however, ...
Anti-VEGF antibodies including off-label bevacizumab (Avastin™, Genentech), ranibizumab (Lucentis™, Genentech), and aflibercept (VEGF Trap-eye (VTE), Eylea) are presently used for the management of various retinal vascular abnormalities [72]. These drugs are different in their pharmacokinetics, structure, and molecular weight. Ranibizumab and aflibercept, which received Food and Drug Administration (FDA) approval for the treatment of neovascular age-related macular degeneration, were designed specifically for intravitreal injection.. Bevacizumab is a full-length humanized murine monoclonal IgG1 antibody with a molecular weight of 149 kDa that received FDA approval for the management of different cancers. 93% and 7% of amino acid sequences of this drug are similar to the human IgG1 and murine antibody, respectively [73]. Bevacizumab recognizes all isoforms of VEGF-A. Despite being off-label, it is used commonly as an intravitreal injection for the management of various retinal diseases [74]. ...

Gene Signal is currently developing aganirsen GS-101 (an antisense oligonucleotide or short naturally occurring DNA strand). GS-101 is a topical medication in the form of eye drops, and is currently being researched for the management of excessive vascular growth in the cornea, also known as neovascularisation GS-101 is a copy of a naturally occurring human gene and acts by inhibiting the expression of IRS-1, a protein required for the formation and growth of new blood vessels. By blocking the expression of this protein in pro-angiogenic conditions (in this case, those with excessive vascular growth), GS-101 inhibits and regresses corneal neovascularisation, which interferes with vision and may be the cause of graft rejection. Phase I, Phase II and Phase III clinical studies have been completed for Gene Signal s GS-101 in the management of Corneal Graft Rejection associated with Neovascularisation (excessive vascular growth of the cornea). The Phase I trial evaluated the safety of GS-101 is ...
Inflammatory angiogenesis is the pathogenic mechanism of various sight-threatening eye diseases, among them corneal neovascularization. Current treatment options include steroids which have undesirable side effects, or anti-VEGF which has only limited efficacy. In an inflammatory environment, however, angiogenesis can be stimulated by numerous factors not directly targeted by anti-VEGF therapy. The aim of this study was to induce corneal inflammation leading to angiogenesis, and investigate the early, differential effects of steroid and anti-VEGF therapy at the cellular, tissue, and gene expression levels. Fifty-two Wistar rats received a single intrastromal corneal suture to induce a controlled inflammatory angiogenic response. Rats were subsequently treated with dexamethasone, rat specific anti-VEGF, or goat IgG (control), topically 4 times daily for 7 days. In vivo confocal microscopy of the cornea was performed longitudinally from 5 h up to 7 d to investigate morphology at the cellular and ...
OXB-202Gene-based treatment for corneal graft rejectionStatus: Phase I/II study in preparationCorneal graft rejectionCornea grafts are one of the most successful tissue transplants, but over time a significant number are rejected due to corneal neovascularisation. Currently, approximately 100,000 transplants are performed each year, but with this representing only 1% of those requiring treatment the number is predicted to increase substantially. Our approach
Results Autologous cultivated oral mucosal epithelial sheets were successfully generated for all 17 patients. All patients were followed up for more than 36 months; the mean follow-up period was 55 months and the longest follow-up period was 90 months. During the long-term follow-up period, postoperative conjunctivalisation and symblepharon were significantly inhibited. All eyes manifested various degrees of postoperative corneal neovascularisation, but it gradually abated and its activity was stable at 6 months after surgery. Best-corrected visual acuity was improved in 18 eyes (95%) during the follow-up periods, and visual acuity at the postoperative 36th month was improved in 10 eyes (53%). ...
RESULTS: The receptors for LXA4, ALX/Fpr-rs-2 and for RvE1, ChemR23 were each expressed by epithelium, stromal keratocytes, and infiltrated CD11b(+) cells in corneas. Compared to the vehicle-treated eye, ATLa-, RvD1-, and RvE1-treated eyes had reduced numbers of infiltrating neutrophils and macrophages and reduced mRNA expression levels of TNF-alpha, IL-1 alpha, IL-1 beta, VEGF-A, VEGF-C, and VEGFR2. Animals treated with these mediators had significantly suppressed suture-induced or IL-1 beta-induced hemangiogenesis (HA) but not lymphangiogenesis. Interestingly, only the application of ATLa significantly suppressed VEGF-A-induced HA ...

PURPOSE To report the outcomes of corneal fine needle diathermy (FND) with adjuvant intrastromal and subconjunctival bevacizumab injection for corneal neovascularization (CN) in children. METHODS Medical records of all children who had undergone FND with adjuvant bevacizumab injection were reviewed retrospectively. Treatment efficacy was evaluated by changes in visual acuity, regression of CN, and clearing of lipid deposits with the aid of slit-lamp color images that were taken before surgical intervention and at last follow-up visit. Postoperative complications were recorded and served to assess the safety of the procedure. RESULTS Nine eyes of 9 patients were included in the study. The mean age of the patients was 8.4 ± 4.2 years (4-15 years) and the mean follow-up time was 18.7 ± 12.2 months (5-35 months). Three eyes had a history of herpes simplex keratitis (HSK), 3 eyes had complete corneal anesthesia, 2 eyes had CN following suture tract infection after corneal transplant for HSK scar and

This is our initial experience with FND represented in only 2 cases, therefore definitive conclusions couldnt be established. Nevertheless, based on our results and after reviewing the two largest series published since FND was described, we found this technique simple, inexpensive and effective in occluding established corneal vessels, the main recognized risk factor for corneal graft rejection and failure. The lack of any major intra and postoperative complications reinforces the safety profile of the procedure. FND can be repeated and performed in any small eye unit around the world, as it does not require specialized equipment ...

The I-CAN study was the first randomised trial of a topical inhibitor of corneal angiogenesis. It showed that topical applications of aganirsen are safe and well-tolerated, that it significantly reduces the relative area of corneal neovascularisation, and that the need for corneal transplantation is reduced in patients suffering from viral keratitis and central neovascularization About neovascularisation and Corneal Grafts The following Orphan Drug designations were granted to Gene Signal for GS 101 - antisense oligonucleotide: On November 7, 2016, the US Food and Drug Administration granted aganirsen an Orphan Drug Designation for Prevention of Corneal Graft Rejection. On 11 June 2014, Orphan designation (EU/3/14/1275) was granted by the European Commission to Gene Signal for aganirsen (GS-101) for the treatment of Central Retinal Vein Occlusion, the most common cause of Neovascular Glaucoma. On April 17, 2007, Orphan designation (EU/3/07/445) was granted by the European Commission to Gene ...
DESCRIPTION (provided by applicant): The overall aim of this grant is to elucidate the novel linkage between copper transport protein Antioxidant1 (Atox1) and NADPH oxidase involved in inflammatory angiogenesis. Ischemic disease is a leading cause of morbidity and mortality in worldwide. Neovascularization is an important repair process in response to ischemia, which depends on angiogenesis, inflammation and reactive oxygen species (ROS). Copper (Cu), an essential micronutrient, is involved in physiological repair processes such as wound healing and angiogenesis as well as in various pathophysiologies including tumor growth, atherosclerosis and inflammatory diseases. Since excess Cu is toxic, bioavailability of intracellular Cu is tightly controlled by Cu transport proteins such as Cu chaperone Atox1. Our laboratories provided the first evidence that Atox1 functions as a Cu-dependent transcription factor to regulate Cu-induced cell growth. Furthermore, we are one of the first to demonstrate that ...

Cornea engraftment is the most common organ transplantation practiced around the world. The cornea is totally devoid of blood or lymphatic vessels, except in a peripheral zone called the limbus. This property, named "corneal angiogenic privilege", is conserved among all mammals to maintain cornea transparency and optimal visual acuity. In pathological conditions such as trauma, infections or hypoxia, blood and lymphatic vessels can grow into the avascular cornea, reducing visual acuity. In case of keratoplasty, it also considerably increases the risk of cornea graft rejection and is so considered as a high-risk keratoplasty. Treatments improving cornea survival after transplantation need to be developed, notably aiming at blocking corneal neovascularization. ...
We investigated the role of interleukin 8 (IL-8) in mediating angiogenesis in human bronchogenic carcinoma. Increased quantities of IL-8 were detected in tumor tissue as compared with normal lung tissue. Immunohistochemical staining of tumors revealed primary localization of IL-8 to individual tumor cells and demonstrated the capacity of tumor to elaborate IL-8. Functional studies that used tissue homogenates of tumors demonstrated the induction of both in vitro endothelial cell chemotaxis and in vivo corneal neovascularization. It is important to note that the addition of neutralizing antisera to IL-8 to these assays resulted in the marked and specific attenuation of these responses. Our observations definitively establish IL-8 as a primary mediator of angiogenesis in bronchogenic carcinoma and offer a potential target for immunotherapies against solid malignancies. ...

A question that has been raised in deliberations over why angiogenesis trials in humans have not demonstrated the robust therapeutic effects seen in earlier animal studies is whether the end points chosen for these trials were "correct"; ie, what is the definition of "successful" therapeutic neovascularization? Furthermore, were the measurement tools that were used to capture such end points adequately sensitive to detect them, even if they were present? Most scientists and clinicians would agree that successful neovascularization requires that new blood vessels be functional, supply the ischemic region with blood, and be stable over time. Our patients would emphasize that irrespective of whether the treatment makes them live longer, they would like to feel better, and hence quality of life is an important end point. Here, we consider whether the identification of molecular markers of neovascularization adds useful information and/or should be incorporated into the definition of "successful" ...

A limitation to the use of biologic therapies is the risk of significant systemic adverse events. Local administration achieves lower systemic exposure to the drug and therefore is likely associated with lower rates of severe adverse events. The use of infliximab eye drops has been investigated as an alternative modality for local drug delivery. The administration of topical infliximab eye drops reduced corneal opacity, perforation, and eyelid fibrosis in a mouse model of corneal alkali burn,19 and improved tear volume, corneal surface regularity, and goblet cell density in a mouse model of dry eye.20 In rabbit models, the use of topical infliximab prevented corneal neovascularization21 and suppressed subconjunctival wound healing after trabeculectomy.22 On the other hand, cerebrovascular accidents are recognized complications of systemic anti-VEGF therapy23 while anti-TNF-α agents are associated with a risk of opportunistic infections, malignancies, infusion reactions, as well as cardiac and ...

AU - Schaff, Hartzell V. PY - 1990. Y1 - 1990. N2 - To determine possible mechanisms by which omental pedicles protect bronchial anastomoses from ischemia, we studied the angiogenic potential of a lipid extract of omentum. A rabbit cornea model was used to quantify neovascularization produced by methanol-chloroform extract of homogenized autologous omentum or perirenal fat. In 22 anesthetized rabbits, 10 μl of omental lipid extract was injected into the cornea. In each animal the opposite eye was used as a control and was injected with a similar volume of extract prepared from perirenal fat. The side of injection of autologous omental fat was randomized and was not known to the investigator who assessed neovascularization on days 4, 7, 14, and 21 after injection. Neovascularization was recorded on ...

In vitro experiments conducted by Saisei Mirai indicate increased rate of maturation of dendritic cells (DCs), a type of immune cell, with 2nd Generation GcMAF. This graph shows specific marker expression of dendritic cells grown from normal peripheral blood with and without 2nd Generation GcMAF after 6 and 8 days cultivation. From this preliminary experiment we observed that 2nd Generation GcMAF increases the rate of maturation of dendritic cells. The ability of dendritic cells to regulate immunity is dependent on DC maturation. The process of DC maturation, results in an increase in the surface expression of costimulatory molecules, morphological changes (such as formation of dendrites), secretion of chemokines, cytokines and proteases, and surface expression of adhesion molecules and chemokine receptors ...
GcMAF is a natural, immune stimulating protein in all healthy people. But, cancer patients need to learn about a degrading enzyme that inhibits GcMAF.
On the face, a 6-0 or 7-0 monofilament suture maybe used, though fast-absorbing gut may be used on the eyelids and ears to obviate the need for suture removal. When the goal of the running alternating simple and vertical mattress suture placement is solely to encourage wound-edge eversion, fine-gauge suture material may be used on the extremities as well. Otherwise, 5-0 monofilament suture material is used if there is minimal tension, and 4-0 monofilament suture is useful in areas under moderate tension where the goal of suture placement is relieving tension as well as epidermal approximation. In select high-tension areas, 3-0 monofilament suture may be utilized as well. ...

The tissue sections were deparaffinized and rehydrated, and endogenous peroxidase activity was quenched with 0.6% H2O2 in methanol. A mouse monoclonal antibody (148.6.1.1, a kind gift from Dr C. Hart, ZymoGenetics, Seattle, Wash) was used for detection of bFGF. This antibody was raised against human recombinant bFGF, and its specificity was determined by Western blot analysis and with an affinity support column containing immobilized human recombinant bFGF.17 A previously described method served for detection of bFGF in MCs.11 Briefly, the sections were treated with hyaluronidase for antigen retrieval. To exclude nonspecific binding, the sections were incubated in a blocking solution containing 3% normal horse serum, 0.5% BSA, and 0.3% Triton X-100 in PBS. They were then incubated overnight with the anti-bFGF antibody (0.05 μg/mL) diluted in PBS containing 2% normal horse serum. The avidin-biotin complex method (ABC-AP Kit, Vector Laboratories) was used to detect the primary antibody with ...
Author Summary Herpes simplex virus-type 1 is the leading cause of infectious corneal blindness in the industrialized world. Most of the morbidity associated with the virus is due to the host response to episodic reactivation of latent virus. Corneal immunologic privilege is associated with a number of factors including the absence of blood and lymphatic vessels. Conversely, corneal hem (blood)- and lymph-angiogenesis driven by inflammation correlate with the loss of privilege. Neovascularization is a common phenomenon in HSV-1 keratitis that correlates with poor prognosis. We have previously discovered HSV-1 elicits corneal lymphangiogenesis through a unique mechanism involving vascular endothelial growth factor (VEGF)-A independent of that described for other insults including transplantation or bacterial infection. However, the viral-encoded product(s) that elicit host production of VEGF-A is(are) unknown. In this paper, we have identified infected cell protein-4 (ICP4) as the primary virus-encoded
The main result of this study is that CXCR3 expression positively modulates ischemia-induced neovascularization, likely through modulation of inflammatory cell infiltration within the ischemic area. This study also extends previous results on the role of MCP-1 in this process and shows a significant impairment in postischemic neovascularization in MCP-1-deficient mice.. Classically, inflammatory cells have been shown to promote neovascularization through various mechanisms, including production of angiogenic factors, secretion of proinflammatory cytokines, and increased matrix degradation.7-9 LPS-induced monocyte accumulation promotes vessel growth, whereas absence of macrophages is associated with a deficient neovascularization response.10,11 A specific role of T cells in this setting was also suggested in Nude mice and in CD4-deficient mice, which exhibit a marked reduction in the angiogenic/arteriogenic process.4,5 In this study, we showed that CXCR3 and its ligands CXCL-10 and CXCL-9 were ...
Cauterization - What is the definition or description of: cauterization? Heat treatment. Cauterization is the term for the use of a device which uses heat to treat tissues, most commonly at surgery to diminish bleeding but also externally for bleeding such as nasal bleeding. It can also be used to remove lesions on the skin like warts and moles.
In the PDT approach, a photosensitizer is administered intravenously, which selectively accumulates in the neovascularized tissue. A dose of carefully calculated laser light is administered directly to the lesions, which activates the photosensitizer causing death to the cells and destroying the vessels. It is important to note that the effect of PDT treatment is photochemical and there is no accompanying thermal reactions. Although the results are a stoppage of blood leakage from the disruption of the vessels, according to the results seen in the TAP study (Treatment of Age-Related Macular Degeneration with Photodynamic Therapy), as reported at the Vitreoretinal Update 99 meeting held just prior to the AAO, the effect appears to be temporary, and as many as four treatments per year may be needed. However, there are indications that the recurrance of bleeding should lessen with time. The problem is the cost of the treatment. Visudyne is expected to be priced at about $1200 per dose, and with ...
