Suppression of angiogenesis and tumor growth by the inhibitor K1-5 generated by plasmin-mediated proteolysis. (1/742)

Proteolytic enzymes are involved in generation of a number of endogenous angiogenesis inhibitors. Previously, we reported that angiostatin, a potent angiogenesis inhibitor, is a proteolytic fragment containing the first four kringle modules of plasminogen. In this report, we demonstrate that urokinase-activated plasmin can process plasminogen to release an angiogenesis inhibitor, K1-5 (protease-activated kringles 1-5). K1-5 inhibits endothelial-cell proliferation with a half-maximal concentration of approximately 50 pM. This inhibitory effect is endothelial-cell-specific and appears to be at least approximately 50-fold greater than that of angiostatin. A synergistic efficacy of endothelial inhibition was observed when angiostatin and kringle 5 (K5) were coincubated with capillary endothelial cells. The synergistic effect is comparable to that produced by K1-5 alone. Systemic treatment of mice with K1-5 at a low dose significantly blocked the fibroblast growth factor-induced corneal neovascularization, whereas angiostatin had no effect at the same dose. K1-5 also suppressed angiogenesis in chicken embryos. Systemic administration of K1-5 at a low dose at which angiostatin was ineffective significantly suppressed the growth of a murine T241 fibrosarcoma in mice. The antitumor effect correlates with the reduced neovascularization. These findings suggest that the plasmin-mediated proteolysis may be involved in the negative switch of angiogenesis.  (+info)

Effect of focal X-ray irradiation on experimental choroidal neovascularization. (2/742)

PURPOSE: Radiation therapy has been used to treat choroidal neovascularization (CNV) in patients with age-related macular degeneration. The in vivo effect of applying focal x-ray irradiation to the eye of rabbits with experimental CNV was investigated. METHODS: CNV was induced in the rabbit eyes by subretinal implantation of gelatin hydrogel microspheres impregnated with basic fibroblast growth factor. Three weeks after implantation, 17 of 34 eyes with CNV lesions accompanied by fluorescein leakage were irradiated with a single dose of 20 Gy; the other 17 eyes were not irradiated and served as the controls. The eyes were examined before irradiation and 1, 2, and 4 weeks after irradiation, by indirect ophthalmoscopy and fluorescein angiography. The degree of a decreasing amount of fluorescein leakage from the CNV lesions after irradiation was graded using a computerized image analysis system and was compared in the irradiated and nonirradiated eyes. These eyes were also examined histologically and immunohistochemically. RESULTS: Fluorescein leakage from the CNV lesions had significantly decreased in the eyes irradiated with 20 Gy compared with the control eyes, throughout the study period (P < 0.05). Histologic and immunohistochemical studies at 4 weeks after irradiation demonstrated that the degree of vascular formation and the number of vascular endothelial cells in the subretinal membrane of the irradiated eyes were less than those of the control eyes. CONCLUSIONS: Focal x-ray irradiation at the ocular region effectively reduced experimental CNV activity. These results support the possibility that radiation therapy may be beneficial in treating CNV.  (+info)

Inhibitory effect of TNP-470 on experimental choroidal neovascularization in a rat model. (3/742)

PURPOSE: To determine whether an angiogenic inhibitor, TNP- 470 (TNP), an analogue of fumagillin, inhibits choroidal neovascularization (CNV) induced by diode laser photocoagulation in a rat experimental model. METHODS: Fundus laser photocoagulation was performed on Brown Norway rats to induce CNV. In the treatment group, TNP was administered intraperitoneally at the time of laser photocoagulation and on day 7 (50 mg/kg at each time). The incidence of CNV formation was evaluated by fluorescein angiography. The retina was collected from the rats on days 1, 3, 7, and 14 after laser photocoagulation, and semiquantitative polymerase chain reaction (PCR) analyses for the expression of mRNA of basic fibroblast growth factor (bFGF) and vascular endothelial growth factor (VEGF) were carried out. Localization of bFGF mRNA was studied by in situ reverse transcription-PCR (RT-PCR). The numbers of positively labeled cells for bFGF mRNA were compared between the TNP treatment and control groups. RESULTS: The incidence of CNV formation was 22.7% in the TNP-treated rats and that in the control rats was 61.4% (P < 0.001). The semiquantitative PCR analyses showed that bFGF mRNA was upregulated on days 3 and 7 in the control rats, but no significant changes were found in TNP-treated rats. There was no detectable difference in VEGF gene expression between the control and TNP-treated rats. bFGF mRNA was detected by in situ RT-PCR in the regenerated retinal pigment epithelial cells and cells of the outer and inner nuclear layers of the control rats. The number of positive cells for bFGF mRNA in the TNP treatment group was significantly smaller than that of the control group (P < 0.05) on days 3 and 14. CONCLUSIONS: TNP- 470 treatment reduced the incidence of laser-induced CNV formation in this experimental model. The expression of bFGF associated with CNV formation was also significantly reduced by the TNP treatment.  (+info)

Dramatic inhibition of retinal and choroidal neovascularization by oral administration of a kinase inhibitor. (4/742)

The most common cause of new blindness in young patients is retinal neovascularization, and in the elderly is choroidal neovascularization. Therefore, there has been a great deal of attention focused on the development of new treatments for these disease processes. Previous studies have demonstrated partial inhibition of retinal neovascularization in animal models using antagonists of vascular endothelial growth factor or other signaling molecules implicated in the angiogenesis cascade. These studies have indicated potential for drug treatment, but have left many questions unanswered. Is it possible to completely inhibit retinal neovascularization using drug treatment with a mode of administration that is feasible to use in patients? Do agents that inhibit retinal neovascularization have any effect on choroidal neovascularization? In this study, we demonstrate complete inhibition of retinal neovascularization in mice with oxygen-induced ischemic retinopathy by oral administration of a partially selective kinase inhibitor that blocks several members of the protein kinase C family, along with vascular endothelial growth factor and platelet-derived growth factor receptor tyrosine kinases. The drug also blocks normal vascularization of the retina during development but has no identifiable adverse effects on mature retinal vessels. In addition, the kinase inhibitor causes dramatic inhibition of choroidal neovascularization in a laser-induced murine model. These data provide proof of concept that pharmacological treatment is a viable approach for therapy of both retinal and choroidal neovascularization.  (+info)

Indocyanine green guided laser photocoagulation in patients with occult choroidal neovascularisation. (5/742)

AIMS: To determine whether indocyanine green (ICG) guided laser photocoagulation of occult choroidal neovascularisations (OCNV) is beneficial for patients with occult choroidal neovascularisation secondary to age related macular degeneration (AMD). METHODS: A prospective pilot study was performed in 21 eyes with OCNV secondary to AMD that could be identified extrafoveolarly or juxtafoveolarly in an early ICG angiographic study. Laser photocoagulation was applied to the neovascular membrane identified in the early ICG angiographic study. RESULTS: Visual acuity ranged from 20/400 to 20/20 (logMAR 0.54 (SD 0.29) before and hand movements and 20/30 (logMAR 0.81 (0.69)) at the last follow up after laser photocoagulation. During the follow up (30 (13) months) vision improved in four eyes (two lines), in seven eyes the initial visual acuity could be stabilised (two lines), in five eyes vision dropped moderately (three to five lines), and in five eyes vision decreased severely (six or more lines). Recurrences (seven patients) or persistent CNV (six patients) was observed in 13 patients. CONCLUSION: This preliminary study of ICG guided laser photocoagulation of occult extrafoveal and juxtafoveal choroidal neovascularisations suggests that this technique may improve the visual prognosis of these patients. Further prospective controlled studies are necessary to confirm these data.  (+info)

OCT imaging of choroidal neovascularisation and its role in the determination of patients' eligibility for surgery. (6/742)

AIM: To evaluate the optical coherence tomographic characteristics of choroidal neovascularisation (CNV) in age related macular degeneration (AMD) and in idiopathic and inflammatory CNV. The use of this technique in the selection of patients for surgery is discussed. METHODS: Ocular coherence tomography (OCT), fluorescein, and indocyanine green angiography were performed in 23 patients affected by AMD complicated by well defined CNV and in 10 patients affected by inflammatory or idiopathic CNV. The neovascular membrane was surgically removed in five age related CNVs, two inflammatory choroidopathies, and two idiopathic CNVs. RESULTS: In inflammatory and idiopathic CNV, the OCT displayed a neovascularisation on the retinal pigment epithelium (RPE). In three cases the CNV was excised with an improvement of visual acuity equal to or greater than two Snellen lines; in a fourth case, the visual acuity after surgery was unchanged. In the cases of AMD the OCT fell into three different patterns: (A) CNV above the RPE (five cases); (B) focal, irregular thickening of the retinal pigment epithelial band (12 cases); (C) CNV above and below the RPE (six cases). The five pattern A CNV patients underwent the surgical excision of the neovascularisation. In four cases the visual acuity improved by two or more Snellen lines; in the fifth case the visual acuity remained unchanged. CONCLUSIONS: The authors suggest that the surgical removal of early age related CNV could be performed in those cases where the OCT shows a neovascular membrane on the RPE, as in idiopathic and inflammatory CNVs.  (+info)

The potential angiogenic role of macrophages in the formation of choroidal neovascular membranes. (7/742)

PURPOSE: To investigate the distribution of inflammatory mediators such as interleukin (IL)-1beta and tumor necrosis factor (TNF)-alpha and angiogenic cytokines such as vascular endothelial growth factor (VEGF) and to identify their cellular source in surgically excised choroidal neovascular membranes (CNVMs) of various origins. METHODS: Immunoperoxidase staining was performed on paraffin-embedded sections of 11 surgically excised CNVMs to identify cellular distribution and localization of cytokines. Immunofluorescent double staining was performed to detect the cellular source of cytokines. RESULTS: Cytokeratin-positive cells were detected in the RPE layer, in stromal cells, and around neovascular vessels. Macrophages identified by their cellular marker CD68 showed almost the same distribution as cytokeratin-positive cells, although they were most prominent in the stroma. A substantial number of neovascular vessels were also immunoreactive to IL-1beta and TNF-alpha. Immunofluorescent double staining revealed that the RPE layers immunopositive for cytokeratin were also immunopositive for all cytokines, whereas stromal cells immunostained for CD68 were positive for IL-1beta and TNF-alpha, but not for VEGF. CONCLUSIONS: These results indicate that IL-1beta and TNF-alpha secreted by macrophages may promote, at least in part, angiogenesis in CNVMs by stimulating VEGF production in RPE cells.  (+info)

Expressions of angiopoietins and Tie2 in human choroidal neovascular membranes. (8/742)

PURPOSE: To elucidate the potential role of angiopoietins and the Tie2 system in choroidal neovascularization. METHODS: Surgically excised choroidal neovascular membranes (CNVMs) were obtained at vitrectomy from five eyes with age-related macular degeneration, three eyes with idiopathic neovascular maculopathy, and two eyes had degenerative myopia and two eyes had angioid streaks. Light microscopic immunohistochemistry was performed to detect cytokines such as vascular endothelial growth factor (VEGF), Ang1, and Ang2 and cellular components such as retinal pigment epithelial (RPE) cells, macrophages, and endothelial cells. Immunofluorescent double staining using confocal microscopy was performed to identify the cell types that secrete specific cytokines. RESULTS: Ang1 and Ang2 were positive in all surgically excised CNVMs, regardless of the primary disease. Double staining revealed that many of the cytokeratin, CD68 and factor VIII positive cells also had Ang1 and Ang2 immunoreactivities. In contrast to Ang1, Ang2 immunoreactivity tends to be higher in the highly vascularized regions of many CNVMs, and the localization was very similar to that of VEGF staining. Almost all vascular structures had prominent immunoreactivity for Tie2, which was confirmed by double staining for Tie2 and factor VIII. Tie2 immunoreactivity was also observed in the RPE monolayer and in pigmented, polygonal, and fibroblast-like cells in the stroma. CONCLUSIONS: Present findings that Ang2 and VEGF are co-upregulated and that Tie2 is expressed in a variety of cell types in CNVMs further support a crucial role of the interaction between VEGF and Ang2 in pathologic angiogenesis of CNVM formation.  (+info)

Purpose : Historically, large animal models of neovascular age-related macular degeneration have been unpredictable, with only 70% of laser-induced choroidal neovascularization (CNV) lesions in non-human primates (NHP) considered clinically relevant. Furthermore, only up to 40% of these CNV lesions are considered ideal, exhibiting Grade IV leakage on fluorescein angiography. This inefficiency leads to excess animal use and high study cost. Previous swine CNV models displayed extensive retinal damage and only minimal choroidal involvement when neovascularization was present. We aimed to create a reproducible, predictable swine model of laser-induced CNV improving efficiency and lowering cost compared to available NHP CNV models. Methods : Yucatan minipigs were used to optimize laser induction of CNV. Bilaterally, six lesions were created using a 532nm green argon laser under direct visualization with a slit lamp and condensing lens. Follow-up examinations included optical coherence tomography ...
purpose. Pigment epithelium-derived factor (PEDF) is a protein produced by the retinal pigment epithelial (RPE) cells. Recent studies have implicated PEDF in activities that are inhibitory to angiogenesis. In this study, the expression of PEDF was investigated in normal rat eyes and in eyes with experimentally induced choroidal neovascularization and compared with the expression of vascular endothelial growth factor (VEGF).. methods. Choroidal neovascularization was induced by laser photocoagulation in rat eyes. At intervals of up to 2 weeks after photocoagulation, the eyes were removed and prepared for in situ hybridization and immunohistochemical study. In situ hybridization was performed with digoxigenin-labeled PEDF riboprobes. Protein expression of PEDF and VEGF was studied immunohistochemically.. results. In normal adult rat eyes, PEDF mRNA was observed mainly in the corneal epithelial and endothelial cells, lens epithelial cells, ciliary epithelial cells, retinal ganglion cells, and the ...

The retinal pigment epithelium (RPE), the outer blood-retinal barrier in the eye, secretes many growth factors to support the normal functions of both the retina and the choroid. Dysfunction of RPE is believed to play a critical role in the pathogenesis of age-related macular degeneration (AMD). Advanced AMD can manifest in either geographic atrophy (dry AMD) or a neovascular form of the disease (wet AMD). Recently our studies indicated that bone morphogenetic protein-4 (BMP4), one growth factor of the transforming growth factor-β (TGF-β) superfamily, may be involved in the molecular switch that determines which advanced form of AMD an individual develops. We demonstrated that BMP4 was highly expressed in the macular RPE and adjacent extracellular matrix of dry AMD patients, and BMP4 mediated oxidative stress induced RPE cell senescence in vitro. However, BMP4 was immunohistochemically absent in RPE in subretinal choroidal neovascularization (CNV) membranes of wet AMD patients. This work ...

It is relatively rare to obtain histology of CNV treated after PDT. Ghazi et al5 and Schnurrbusch et al6 reported the histological findings in surgically excised classic CNV treated with PDT. Ghazi et al studied one specimen by electron microscopy. The authors concluded that PDT causes endothelial cell damage, thrombus formation, and vascular occlusion. Schnurrbusch et al studied two recurrent CNV. The authors concluded that the evidence of fluorescein leakage from the CNV and enlargement of the neovascular complex following PDT could be related to new vessel growth and recanalisation of occluded vessels. RPE disturbances were thought to be related to the original pathology or as a result of PDT. Our specimen appeared to lack vessels where the RPE cell layer was fragmented but was vascular where the RPE cell layer was intact. These two regions may correspond to the original (PDT treated) CNV and its recurrence respectively. Bynoe et al have described the non-even distribution of blood vessels ...

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 ...
PIC is an idiopathic inflammatory disorder that typically occurs in young (15-55 years), white, myopic women. Presenting symptoms are blurred vision and scotomas with or without flashes of light.(2) The symptoms are usually unilateral, but most patients show bilateral fundus involvement.(2,3) PIC is characterized by multifocal choroidal lesions (yellow-white lesions of the inner choroid and retinal pigment epithelium of approximately 100-300 ìm in size), usually distributed throughout the posterior pole but sparing the peripapillary region.(2,4) There are no other signs of ocular inflammation elsewhere in the eye. Visual prognosis is generally good since the lesions usually evolve into atrophic scars; however, choroidal neovascularization may develop in 17% to 40% of patients, potentially threatening central vision if untreated.(4-7 ...
By using this easy, fast and cheap model of ischaemia the first steps of choroidal neovascularization (CNV) were shown: the increase of synthesis of HIF-1α and VEGF which is very likely responsible for the formation of gaps between endothelial cells and the formation of fenestrated endothelial cell projections into the vessel lumen. Their abundance can block perfusion of blood cells and thereby inhibit closure of the endothelial gaps by platelets, but still allow the flow of plasma.

To compare the long-term efficacy of ranibizumab versus bevacizumab for myopic choroidal neovascularization (CNV). This was a retrospective, multicenter, comparative, non-randomized study of 64 consecutive patients with myopic CNV treated with ranibizumab (22 patients) or bevacizumab (42 patients). Best-corrected visual acuity (BCVA) and central foveal thickness (CFT) on optical coherence tomography were evaluated before and after treatment. All the patients were followed for at least 12 months. BCVA (logarithm of the minimal angle of resolution) improved from 0.63 ± 0.30 to 0.43 ± 0.27, 0.41 ± 0.37, 0.40 ± 0.39, 0.39 ± 0.43, and 0.39 ± 0.42 at 1, 2, 3, 6, and 12 months after treatment in the ranibizumab group, and from 0.67 ± 0.28 to 0.52 ± 0.31, 0.49 ± 0.31, 0.47 ± 0.31, 0.42 ± 0.32, and 0.46 ± 0.43 in the bevacizumab group (all P < 0.05 compared with baseline BCVA in each group). CFT decreased by 20.21%, 19.58%, and 22.43% from the baseline 304 ± 76 μm at 3, 6, and 12 months after

February is age related macular degeneration (AMD) and low vision awareness month.. Age related macular degeneration (AMD) is one of the leading causes of loss of vision in adults over age 65. AMD is a condition that causes a breakdown of the macula in the eye which is responsible for sharp vision in the center of your field of view.. Age Related Macular Degeneration Symptoms. The first warning signs of age related macular degeneration are usually blurriness or blind spots in the central vision. Since the symptoms typically come on slowly and painlessly, the effects are sometimes not noticed until the disease has reached a later stage. This is why it is crucial to schedule a routine eye exam, particularly once you turn 65.. Risk Factors for Age Related Macular Degeneration. There are a number of factors that put you at greater risk of developing AMD including race (Caucasian), being over the age of 65, smoking and family history. If you are categorized as being at greater risk, annual eye ...

Our lab studies the contribution of inflammatory mediators in neovascular age-related macular degeneration (AMD). AMD is a degenerative condition of the macula (the central retina) and is the most common cause of vision loss in individuals 50 or older. Neovascular or "wet" AMD occurs when new blood vessels invade the macula leading to photoreceptor death. Inflammatory mediators, such as prostaglandins, are thought to be involved in this process. Our lab has already shown that inhibition of cyclooxygenase (COX) and thereby prostaglandins with nonsteroidal anti-inflammatory drugs (NSAIDs) can inhibit neovascularization in an animal model of AMD. Further downstream inhibition of specific prostaglandin subtypes or their receptors should enable more targeted therapeutic strategies. The laboratory uses cellular and molecular approaches to investigate the role of inflammatory mediators in neovascularization and relies on animal models of AMD to measure therapeutic effects.. ...

BACKGROUND: Eyes with high myopia (axial length ≥ 26.5 mm) do not just have a different size. Due to morphological and structural changes there is a considerably increased risk for many different secondary diseases. OBJECTIVE: Determination of the incidence and mortality in high myopia, discussion of effects and clinical signs, presentation of treatment recommendations and counselling. MATERIAL AND METHODS: A systematic search of the literature was carried out and a discussion on basic principles and epidemiological investigations is presented. RESULTS: Findings due to high myopia are not in a closed state but undergo continuous changes. Choroidal neovascularization (adjusted prevalence 2.5-5%), staphyloma, foveoschisis and peripheral retinal degeneration are examples of problems contributing to the increased rate of visual impairment and blindness related to myopia. High myopia is associated with a clearly increased risk of retinal detachment after lens surgery (hazard ratio 6.1) and ...

渗出型老年性黄斑变性(wAMD)以脉络膜新生血管(CNV)的进行性生长为主要特征。抗血管内皮生长因子(VEGF)药物在控制CNV的发展和改善视功能中已取得一定成果,但其仍存在频繁注射、容易耐药等不足。放射治疗(放疗)可使局部炎症细胞群失效,CNV在无周细胞覆盖下不稳定且无VEGF存在,血管内皮细胞被诱导凋亡。因此,放疗被认为是抗VEGF治疗的一类潜在辅助治疗手段。目前临床试验治疗wAMD主要运用黄斑前近距离放疗和远距离立体定向放疗(SRT)。其中,SRT或许可作为接受抗VEGF治疗患者的首选辅助治疗方式。了解放疗用于wAMD治疗的进展,可为wAMD的临床研究提供参考。
Neovascular age-related macular degeneration (nAMD) is the commonest cause of severe visual impairment in older adults in Caucasian white populations. Polypoidal choroidal vasculopathy (PCV) has been described as a separate clinical entity differing from nAMD and other macular diseases associated with subretinal neovascularization. It remains controversial as to whether or not PCV represents a sub-type of nAMD. This article summarizes the current literature on the clinical, pathophysiological and epidemiological features and treatment responses of PCV and compares this condition to nAMD. Patients with PCV are younger and more likely Asians, and eyes with PCV lack drusen, often present with serosanguinous maculopathy or hemorrhagic pigment epithelial detachment, and have differing responses to photodynamic therapy and anti-vascular endothelial growth factor (VEGF) agents. There are also significant differences in angiographic and optical coherence tomography features between PCV and nAMD. ...

The recent development of photodynamic therapy (PDT) for the treatment of subfoveal choroidal neovascularisation (CNV) has provoked considerable interest amongst UK ophthalmologists, patients, hospital managers, public health physicians and the media. The recent publication of the Treatment of Age-related Macular Degeneration (TAP) report1 and the further data expected soon from this and other randomised clinical trials is likely to have a major impact on service provision in the UK. The vast majority of cases of subfoveal CNV are caused by age-related macular degeneration (AMD) but other causes include pathological myopia, angioid streaks and punctate inner choroidopathy, especially in younger patients. Until very recently confluent argon laser photocoagulation has been the only treatment modality of proven clinical efficacy but after initial enthusiasm its role has become restricted to the treatment of eyes with extrafoveal CNV. In addition to PDT other therapeutic options for subfoveal CNV ...
Lactoferrin, a type of glycoprotein, is contained in exocrine fluids such as tears, breast milk, sweat, and saliva, and is known to have anti-microbial, antioxidant, and anti-cancer effects. In the ophthalmological field, topical administration of lactoferrin has been reported to have a therapeutic effect in a murine dry eye model. Hypoxia-inducible factor (HIF) regulates various gene expressions under hypoxia, including vascular endothelial growth factor (VEGF), and is considered as an alternative target for neovascular ocular diseases such as age-related macular degeneration (AMD). We previously screened natural products and identified lactoferrin as a novel HIF inhibitor. In this study, we confirmed that lactoferrin has an HIF inhibitory effect and a therapeutic effect in a murine model of neovascular AMD ...

This report by a group of UK retina specialists and health professionals considers best practice recommendations for the management of sight-threatening neovascular age-related macular degeneration (nAMD), based on collective experience and expertise in routine clinical practice. The authors provide an update for ophthalmologists, allied healthcare professionals and commissioners on practice principles for optimal patient care and service provision standards. Refinement of care pathways for nAMD has improved access to intravitreal anti-vascular endothelial growth factor therapy but there are still variations in care and reported outcomes between clinic centres. Innovative organisational models of service provision allow providers to better match capacity with increasing demand. The authors review the recent NICE guideline for diagnosis and management of AMD, considerations for switching therapies and stopping treatment and need for regular monitoring of non-affected fellow eyes in patients with ...

TY - JOUR. T1 - Scotomas of age-related macular degeneration detected and characterized by means of a novel three-dimensional computer-automated visual field test. AU - Nazemi, Paul P.. AU - Fink, Wolfgang. AU - Lim, Jennifer I.. AU - Sadun, Alfredo A.. PY - 2005/6. Y1 - 2005/6. N2 - Purpose: We used the recently devised three-dimensional computer-based threshold Amsler grid test to acquire and identify typical patterns of visual field defects (scotomas) caused by age-related macular degeneration (AMD). Methods: Patients with AMD traced on a computer touch screen the borders of those areas on an Amsler grid that were missing from their field of vision. Scotomas were repeatedly outlined and recorded at different grid contrast levels. The resulting three-dimensional "hole" in the central 25° of the visual field was further characterized by its slope, location, shape, and depth. The results were compared with fundus photographs and fluorescein angiograms. Results: Twenty-five patients and 41 eyes ...

PURPOSE: To compare 1-year functional and anatomic outcomes of intravitreal bevacizumab (IVB) and photodynamic therapy plus intravitreal triamcinolone (PDT+IVTA) combination in patients with neovascular age-related macular degeneration (AMD). METHODS: In this prospective, randomised, controlled clinical trial, 28 patients were included. All patients were randomised 1 : 1 to 0.04 ml/1 mg of IVB or PDT plus same day 0.1 ml/4 mg IVTA (PDT+IVTA). Follow-up examinations were performed in monthly intervals in IVB group and every 3 months in PDT+IVTA group. Main outcomes were change in mean visual acuity (VA), mean central retinal thickness (CRT) and the mean number of treatments. RESULTS: At month 12, mean VA improved to a 1.5-line gain in IVB group, and lost three letters in PDT+IVTA group (P=0.02). Mean CRT was reduced from 357 microm at baseline to 244 microm at month 12 in IVB group and from 326 microm to 254 microm, respectively, in PDT+IVTA group (P=0.8). The mean number of treatments was 6.8 in ...
