PURPOSE: To evaluate the efficacy of an optical coherence tomography (OCT)-based diagnosis of polypoidal choroidal vasculopathy (PCV) in Korean patients. METHODS: This retrospective, observational case series included 263 eyes of 263 patients (147 eyes with PCV and 116 eyes with typical exudative, age-related macular degeneration [AMD]) who had been diagnosed with treatment naïve exudative AMD. Eyes with three or more of the following OCT findings were diagnosed with PCV: multiple retinal pigment epithelial detachment (RPED), a sharp RPED peak, an RPED notch, a hyporeflective lumen representing polyps, and hyperreflective intraretinal hard exudates...

Age-related macular degeneration (AMD) in the Japanese often shows different clinical features from those described in Caucasians. For example, we often observe choroidal neovascularization (CNV) in elderly patients without drusen in the fundus. The high incidence of polypoidal choroidal vasculopathy (PCV) in AMD among Japanese is well-known. The reason why such differences occur in clinical manifestations of AMD has been one of my main interests. In this review article, I will discuss the characteristics of AMD in the Japanese population, as found in our recent study...

Optical coherence tomography (OCT) is a noninvasive imaging modality providing high-resolution images of the central retina that has completely transformed the field of ophthalmology. While traditional OCT has produced longitudinal cross-sectional images, advancements in data processing have led to the development of en-face OCT, which produces transverse images of retinal and choroidal layers at any specified depth. This offers additional benefit on top of longitudinal cross-sections because it provides an extensive overview of pathological structures in a single image...

PURPOSE: To suggest a clinical distinction between idiopathic polypoidal choroidal vasculopathy (PCV) and secondary polyps associated with neovascular age-related macular degeneration (NV-AMD). METHODS: The study was a retrospective case series of 52 eyes of 52 consecutive patients (31 females and 21 males) diagnosed with PCV.

PURPOSE: To investigate the causes of acute spontaneous submacular hemorrhage with indocyanine green angiography (ICGA). METHODS: Retrospective observation case series. A total of 51 eyes from 51 patients with newly developed spontaneous submacular hemorrhage were enrolled. Best-corrected visual acuity (BCVA), fundus photography, fluorescein angiography, spectral domain optical coherence tomography (OCT), and ICGA at baseline were analyzed. The extent of hemorrhage using fundus photography, height of hemorrhage, and central foveal thickness measured by OCT was analyzed to compare the diagnostic and nondiagnostic groups...

PURPOSE: The purpose of the study was to compare the rates and characteristics of retinal pigment epithelial (RPE) tears between typical exudative age-related macular degeneration (tAMD) and polypoidal choroidal vasculopathy (PCV) after injection of intravitreal ranibizumab (IVR). METHODS: In total, 836 eyes from 784 patients with exudative AMD treated with IVR were analyzed. The presence, type, size, and height of pigment epithelial detachment (PED) in OCT before injection were evaluated, and the occurrence rate of RPE tears within three months of injection between tAMD and PCV was compared...

PURPOSE: To evaluate visual and anatomic outcomes in response to the conversion of treatment in patients with neovascular age-related macular degeneration (AMD) and polypoidal choroidal vasculopathy (PCV) refractory to previous treatment. We also investigated the effect of genetic factors. METHODS: We recruited patients with AMD or PCV refractory to ranibizumab and initiated aflibercept treatment. Changes in the logarithm of minimum angle of resolution (logMAR) and central retinal thickness (CRT) measured using optical coherence tomography (OCT) 6 months after the conversion were compared between the AMD and PCV groups...

BACKGROUND: We compared the visibility of retinal and choroidal pathologies using high-penetration optical coherence tomography (HP-OCT) with a long-wavelength light source (1,050 nm) and conventional spectral-domain OCT (SD-OCT) in age-related macular degeneration (AMD). METHODS: One hundred and forty-six eyes were included: 63 eyes with AMD, 79 eyes with polypoidal choroidal vasculopathy (PCV), and four eyes with retinal angiomatous proliferation. The SD-OCT and HP-OCT images were compared using the grading criteria to grade the visibility of the retinal changes, the line corresponding to the retinal pigment epithelium (RPE), and the chorioscleral interface (CSI)...
