Active clinical trials for "White Dot Syndromes"

To investigate the efficacy of retinal electromagnetic stimulation and sub-tenon autologous platelet rich plasma in the treatment of deep retinal capillary ischemia.

Intravitreal injection of Bevacizumab in patients with Neovascular Membranes secondary to intraocular inflammation. We injected a single injection of Bevacizumab (2.5 mg/0.1 ml) and evaluate visual acuity , Fluorescein angiogram and retinal thickness by Optical Coherence Tomography (OCT) in 4 patients with Vogt Koyanagi Harada disease, 1 patient with Serpiginous Choroidopathy and 1 patient with Multifocal Choroiditis.

Anti-VEGF therapy has been proven efficacious for the wet (neovascular) form of macular degeneration and may be beneficial for the treatment of choroidal neovascularization (CNV) due to other causes. The limitation of this type of treatment is the necessity for frequent intraocular injections. The purpose of this study is to determine if using anti-VEGF therapy in combination with photodynamic therapy can reduce the number of treatments needed with monotherapy while achieving similar visual results. There are ongoing multicenter trials evaluating combination therapy in patients with wet AMD but no similar trial for patients with CNV due to non-AMD causes. Therefore, in this study the investigators will focus on patients with CNV not due to AMD.

One complication of uveitis which is driven by an increase in VEGF is the formation of inflammatory ocular neovascularization (ION). Here, we analyze the therapeutic role of intravitreal bevacizumab in ION not responding to standard therapy (systemic and ocular corticosteroids and systemic immunosuppressants) in a multicenter retrospective study.The natural history of subfoveal choroidal new vessels histoplasmosis, multifocal choroiditis, Harada and other inflammatory chorioretinal disorders has been very guarded, but with this new approach, we hope to stop the visual loss in these relatively young patients.

To report the long term prognosis in patients with punctate inner choroidopathy (PIC) or multifocal choroiditis (MFC) and associated zonal outer retinopathy (ZOR).

To evaluate the long-term outcome of active choroidal neovascularization (CNV) in punctate inner choroidopathy (PIC) or multifocal choroiditis (MFC) after anti-vascular endothelial factor treatment.

Aim of the work PIC in pathological myopia has not been well documented due to difficult in diagnosis we conducted this retrospective study to characterize the clinical features of PIC in high myopic eye. To show the diagnostic criteria of PIC lesions in high myopic patients. Find out the prevalence of PIC related 'patchy atrophy' To determine risk factor for developed PIC in a series of highly myopic patients. Role of PIC in progression of high myopia. Calculate the progression rate of PIC related lesion, by the size change during follow-up. Search about complication of PIC in myopia. Patient and Methods This retrospective observational case series study included patients with high myopia who had been examined and followed-up in the High Myopia Clinic of the Tokyo Medical and Dental University. Approval from Ethics Committee of Tokyo Medical and Dental University was obtained, adhering to the tenets of Declaration of Helsinki. Signed informed consent documentation was obtained from all participants. All study participants underwent a detailed ophthalmologic examination at baseline and at each follow-up visit. The examinations included measurements of best-corrected visual acuity (BCVA) using a Landolt C chart, refraction, slit lamp biomicroscopy, biometry for determination of axial length, (IOL Master; Carl Zeiss Meditec Co, Jena, Germany), fundus examination in medical mydriasis, fluorescein angiography, was performed with and colour fundus photography , and assessment of fundus autofluorescence (TRC-50DX; Topcon, Tokyo, Japan) a or the Heidelberg Spectralis HRA system. Swept source Optical coherence tomography (OCT) used in assessment of the RPE and photoreceptors using a (DRI-OCT;Topcon, Tokyo, Japan). As scanning protocols, 9 mm or 6 mm radial with 12 equal meridian scans were performed. The swept-source OCT device has an A-scan repetition rate of 100 000 Hz, and its light source operates in the wavelength range of 1 μm.
