    1. Multimodal Imaging Characteristics and Functional Test Findings in a Case of Acute Macular Neuroretinopathy Accompanied by Behçet Disease

      Multimodal Imaging Characteristics and Functional Test Findings in a Case of Acute Macular Neuroretinopathy Accompanied by Behçet Disease

      A 23-year-old male presented with a complaint for central scotoma in his right eye. He had been diagnosed with Behçet Disease 3 years ago. Best-corrected visual acuity (BCVA) was 20/20. Anterior chamber and fundus examinations were unremarkable. Optical coherence tomography revealed a paracentral area of outer nuclear layer thinning. Infrared reflectance showed a well-defined, circular, hyporeflective area. Optical coherence tomography angiography revealed an area of capillary dropout in deep retinal capillary plexus corresponding to that hyporeflective lesion. Microperimetry test showed decreased macular sensitivity on the lesion area and the loss of the macular integrity. In multifocal electroretinogram, diminished ...

    2. The Use of Optical Coherence Tomography Angiography in the Diagnosis of Inflammatory Type 1 Choroidal Neovascularization Secondary to Tuberculosis: A Case Report

      The Use of Optical Coherence Tomography Angiography in the Diagnosis of Inflammatory Type 1 Choroidal Neovascularization Secondary to Tuberculosis: A Case Report

      Purpose : To report a case of choroidal neovascularization (CNV), which was not obvious with dye angiography but was detected with optical coherence tomography angiography (OCTA). Methods : A 50-year-old female presented with decreased vision in her right eye. Funduscopic examination revealed a swollen hyperemic disc, peripapillary exudation, and choroidal infiltration. Results : Optical coherence tomography revealed intraretinal cysts, subretinal fluid in the macular region, and subretinal hyperreflective material in the papillomacular area. Fluorescein angiography revealed early hypofluorescence in the areas of choroidal infiltrations, and indocyanine green angiography (ICGA) also showed hypocyanescence corresponding to these infiltrations and revealed a faint hypocyanescence in the ...

    3. Evaluation of the choroidal features in pachychoroid spectrum diseases by optical coherence tomography and optical coherence tomography angiography

      Evaluation of the choroidal features in pachychoroid spectrum diseases by optical coherence tomography and optical coherence tomography angiography

      Purpose: To evaluate choroidal area, stroma/lumen ratio, choriocapillaris vessel density, and choriocapillaris flow area in eyes with central serous chorioretinopathy, uncomplicated pachychoroid, and pachychoroid pigment epitheliopathy using enhanced depth imaging-optical coherence tomography and optical coherence tomography angiography. Materials and Methods: This retrospective study analyzed enhanced depth imaging-optical coherence tomography and optical coherence tomography angiography scans of 142 eyes of 92 patients with central serous chorioretinopathy, uncomplicated pachychoroid, and pachychoroid pigment epitheliopathy. The choroidal area and stroma/lumen ratio were measured by binarization of enhanced depth imaging-optical coherence tomography images. Choriocapillaris vessel density and choriocapillaris flow area were measured at ...

    4. Vascular and structural alterations of the choroid evaluated by optical coherence tomography angiography and optical coherence tomography after half-fluence photodynamic therapy in chronic central serous chorioretinopathy

      Vascular and structural alterations of the choroid evaluated by optical coherence tomography angiography and optical coherence tomography after half-fluence photodynamic therapy in chronic central serous chorioretinopathy

      Purpose To concurrently evaluate the effect of half-fluence photodynamic therapy (hf PDT) on choriocapillaris (CC) perfusion and choroidal structure in chronic central serous chorioretinopathy (CSC). Methods This prospective study included 48 eyes of 41 patients with chronic CSC. Enhanced depth imaging optical coherence tomography and optical coherence tomography angiography (OCTA) images were analyzed. Choroidal area (CA), luminal area (LA), and stromal area (SA) were computed using Image J software. Results One month after hf-PDT, total CA decreased to 1.312 mm 2 from 1.490 mm 2 ( p  < 0.001), LA decreased to 0.981 mm 2 from 1.097 ...

    5. The use of optical coherence tomography angiography in pachychoroid spectrum diseases: a concurrent comparison with dye angiography

      The use of optical coherence tomography angiography in pachychoroid spectrum diseases: a concurrent comparison with dye angiography

      Purpose The study objective was to compare dye angiography and optical coherence tomography angiography (OCTA) in detecting choroidal neovascuarization (CNV) in patients presenting with pachychoroid features and flat irregular pigment epithelial detachment (PED). Methods Nineteen eyes of 17 patients, presenting with flat PED and pachychoroid features, and without age-related macular degeneration or any other degenerative change, were analyzed. Fuorescein angiography (FA)/Indocyanine green angiography (ICGA) and OCTA were performed during the same visit. Subfoveal choroidal thickness was measured by enhanced depth imaging using spectral domain optical coherence tomography. Results The mean age of the patients was 59.1 years. Mean ...

    6. Macular Involvement and Response to Steroid Therapy Demonstrated by Optical Coherence Tomography in Non-arteritic Anterior Ischaemic Optic Neuropathy

      Macular Involvement and Response to Steroid Therapy Demonstrated by Optical Coherence Tomography in Non-arteritic Anterior Ischaemic Optic Neuropathy

      Two consecutive patients with anterior non-arteritic ischaemic optic neuropathy were evaluated with spectral-domain optical coherence tomography. The optical coherence tomographic scans revealed subfoveal fluid and intraretinal fluid extending from the optic disc margin toward the fovea that made us think that the submacular fluid appeared to arise from the peripapillary region. Fluorescein angiography showed no accumulation in the macular area, whereas leakage and staining of the optic nerve was present. After systemic corticosteroid therapy, the submacular fluid decreased promptly and the visual acuity improved. Subretinal-fluid-associated disc oedema may develop in some patients with NAION and contribute to the visual loss ...

    7. Unilateral acute maculopathy related to hand, foot, and mouth disease: OCT and fluorescein angiography findings of a very rare disease

      Unilateral acute maculopathy related to hand, foot, and mouth disease: OCT and fluorescein angiography findings of a very rare disease

      Background: Hand, foot, and mouth disease is a contagious enteroviral infection occurring primarily in children and characterized by vesicular palmoplantar eruptions and erosive stomatitis. There are very few cases of unilateral acute idiopathic maculopathy associated with hand, foot, and mouth infection. We described a case with unilateral outer retinitis occurring a few days after the onset of disease. Methods: A 30-year-old man with reduced vision in his right eye underwent complete ophthalmologic examination including fluorescein angiography and spectral optical coherence tomography. Results: Fundus fluorescein angiography demonstrated mottled hyperfluorescence in the early phase and leakage in the late phase. Spectral domain ...
