Choroidal osteoma with choroidal excavation and associated neovascular membrane: An OCT-angiography study.

2017

Abstract Clinical case A case is presented of a unilateral choroidal osteoma with choroidal excavation and associated neovascular membrane that was studied using OCT-angiography. The OCT and OCT-angiography revealed an area of choroidal excavation and an active neovascular membrane. Three doses of aflibercept were administered to the patient, which stabilized the neovascularisation. Discussion OCT-angiography was used to analyze the morphology of the superficial vascular network of the osteoma, as well as to monitor the evolution of the neovascular membrane.

Surgical management of subfoveal choroidal neovascular membranes in age-related macular degeneration by macular relocation: experiences of an early-s…

2009

The MARAN (Macular Relocation in Age-related Neovascular disease) trial was planned to assess the effectiveness of full macular relocation (MR) in patients with neovascular age-related macular degeneration (AMD).Randomised, prospective, controlled clinical trial.Patients suffering from visual loss because of AMD were randomised to either surgery or a control group receiving standard treatment (observation or photodynamic therapy (PDT)). The primary end point was the change of visual acuity (VA) (ETDRS) 52 weeks after randomisation compared with initial VA, and secondary end points included reading performance, contrast sensitivity, stability of fixation, eye-specific quality of life, and th…

Multifocal choroiditis: Indocyanine green angiographic features

2001

The aim of this study is to retrospectively evaluate the indocyanine green (ICG) angiographic features in 13 patients affected by multifocal choroiditis. We identified two clinical and angiographic patterns. The ‘active’ pattern showed hypofluorescence up to the late phases and more extensive choroidal involvement than presumed by ophthalmoscopy and fluorescein angiography. In the ‘inactive’ pattern, ICG angiography showed hypofluorescence during all the phases: no increase in lesion number was observed between early and late phases. Choroidal neovascularization was present in 10 patients, and it was bilateral in 2 of these: it occurred only in the inactive stage. The appearance of choroida…

Back pain after photodynamic therapy with verteporfin.

2005

Purpose To report the incidence of back pain after photodynamic therapy, which suggests methods for prevention that are related to its pathogenesis. Design Retrospective case series. Methods We retrospectively observed 548 patients who had undergone photodynamic therapy with verteporfin. Results Of 548 patients at the first treatment, 14 patients (2.6%) experienced pain during the infusion. Eleven patients were being treated for age-related macular degeneration; their mean age was 81 years, which significantly differed from the mean age of the overall age-related macular degeneration group ( P = .003). The pain was mild in eight patients, moderate in four patients, and severe in two patient…

Beals–Hecht syndrome and choroidal neovascularization

2010

PURPOSE To describe a case of choroidal neovascularization (CNV) in a female diagnosed with Beals-Hecht syndrome. METHODS A retrospective, interventional case is described in a 26-year-old female complaining of metamorphopsia and visual loss in her left eye (counting fingers). The fluorescein angiogram and the optical coherence tomography supported the diagnosis of CNV. Intravitreal ranibizumab was administered. RESULTS After the third intravitreal ranibizumab, her visual acuity improved to 0.8 and the morphology of the macular area was restored. CONCLUSIONS To our knowledge this is the first report of CNV in Beals-Hecht syndrome treated with ranibizumab. Self-monitoring by periodically per…

Hyaluronic acid based nanohydrogels fabricated by microfluidics for the potential targeted release of Imatinib: Characterization and preliminary eval…

2019

Abstract Microfluidics is emerging as an innovative technique for the “on chip” fabrication of nanoparticles for drug delivery applications. Here, by using an amphiphilic derivative of hyaluronic acid as a starting macromolecule, nanohydrogels loaded with Imatinib were produced by the microfluidic procedure in order to develop an innovative therapeutic tool for the treatment of retinal neovascularization. Both cyRGDC functionalized and non-functionalized nanohydrogels were designed and fabricated by using the same technique. The targeting efficiency of the obtained nanosystems was studied in vitro on human retinal pigment epithelial cells (HRPEpiC) and human umbilical vein endothelial cells…

Clinical Outcome and Subjective Quality of Life after Photodynamic Therapy in Patients with Age-Related Macular Degeneration

2005

PURPOSE. Whereas the efficacy of photodynamic therapy (PDT) in preventing the progression of age-related macular degeneration (ARMD) is established, its effect on quality of life is under discussion. METHODS. All patientswho underwent PDT during 2000 and 2001 at the University Eye Hospital of Mainz were interviewed using a standardized 82-item questionnaire on quality of life and patient satisfaction in ophthalmologic patients. Information was assessed in terms of 82 questions; global scores ranging from 1.0 (optimum self-estimated quality of life) to 4.0 (worst) were derived. Cataract patients' scores were used to characterize the ARMD patients' subjective outcome; the latter were then rel…

Outcomes of treatment of pediatric choroidal neovascularization with intravitreal antiangiogenic agents: the results of the KKESH International Colla…

2014

Purpose: To evaluate safety and clinical results of intravitreal antiangiogenic agents for choroidal neovascularization in pediatric patients. Methods: Retrospective, multicenter, interventional case series. A total of 45 eyes of 39 pediatric patients with choroidal neovascularization of various etiologies were treated with intravitreal injection of antiangiogenic agents (1.25 mg per 0.05 mL of bevacizumab or 0.5 mg per 0.05 mL of ranibizumab). Results: There were 24 girls and 15 boys with group median age of 13 years (range, 3–17 years). Mean follow-up period was 12.8 months (range, 3–60 months). Median visual acuity in terms of logarithm of the minimum angle of resolution at presentation …

RESVEGA, a Nutraceutical Omega-3/Resveratrol Supplementation, Reduces Angiogenesis in a Preclinical Mouse Model of Choroidal Neovascularization

2021

Age-related macular degeneration (AMD) is an eye disease that is characterized by damage to the central part of the retina, the macula, and that affects millions of people worldwide. At an advanced stage, a blind spot grows in the center of vision, severely handicapping patients with this degenerative condition. Despite therapeutic advances thanks to the use of anti-VEGF, many resistance mechanisms have been found to accentuate the visual deficit. In the present study, we explored whether supplementation with Resvega®, a nutraceutical formulation composed of omega-3 fatty acids and resveratrol, a well-known polyphenol in grapes, was able to counteract laser-induced choroidal neovascularizat…

PHOTODYNAMIC THERAPY WITH VERTEPORFIN FOR CHOROIDAL NEOVASCULARIZATION ASSOCIATED WITH RETINAL PIGMENT EPITHELIAL DETACHMENT IN AGE-RELATED MACULAR D…

2007

Abstract PURPOSE: To assess the effectiveness of photodynamic therapy (PDT) with verteporfin for choroidal neovascularization (CNV) associated with retinal pigment epithelium detachment (PED) in age-related macular degeneration. METHODS: Thirty eyes of 26 patients with CNV and PED were treated with PDT. The eyes were divided in two groups based on CNV location in relation to PED; group 1 included 13 eyes with CNV within PED, and group 2 included 17 eyes with CNV at the edge of PED. The median follow-up was 16 months. RESULTS: Patients received a mean +/- SD of 2.83 +/- 1.26 treatments (range, 1-6 treatments). In the whole cohort, the mean preoperative visual acuity changed from 20/144 (0.86…
