Purpose: The purpose of this study was to investigate the relationship between the ocular perfusion pressure (OPP) and subfoveal choroidal thickness (CT) in eyes with early age-related macular degeneration (AMD) with or without reticular pseudodrusen (RPD). Methods: We evaluated the clinical history, blood pressure parameters, fundus photography, and optical coherence tomography images of consecutive patients with early AMD. We calculated the mean OPP from blood pressure and intraocular pressure

BACKGROUND: To investigate the characteristics of retinal vessels and retinal thickness in eyes with early age-related macular degeneration (AMD) with or without reticular pseudodrusen. METHODS: We retrospectively evaluated the clinical history and optical coherence tomography (OCT) and OCT angiography images of consecutive patients with early AMD. We calculated the retinal vessel densities of the superficial and deep capillary plexus with the ImageJ software (National Institutes of Health, Beth

Chronic MH has features distinct from those of acute symptomatic MH on optical coherence tomography. These findings provide useful insight for the differentiation of chronic MH from acute MH.

We sought to compare the retinal thickness measurements collected using different optical coherence tomography (OCT) devices. This prospective study included 21 healthy cases, and the retinal thickness was measured using the PLEX Elite (Carl Zeiss Meditec, Dublin, California, USA), DRI OCT-1 Atlantis (Topcon Corp, Tokyo, Japan), Cirrus 5000 HD-OCT (Carl Zeiss Meditec), and Spectralis OCT (Heidelberg Engineering, Heidelberg, Germany), respectively. The mean central retinal thickness (CRT) and mea

This result may suggest that manifest CSC occurs in patients with thick choroids both within and outside the macula, especially when subfoveal CT is increased.

PURPOSE: To investigate ocular perfusion pressure (OPP) in patients with central serous chorioretinopathy (CSC) and pigment epitheliopathy (PE). METHODS: In this retrospective study, we included patients with acute idiopathic unilateral CSC and age- and sex-matched normal controls. The patients with CSC were classified into two groups according to the PE presence on their fellow eyes. We compared OPP among CSC patients with or without PE and normal controls. RESULTS: Among a total of 47 patients

PURPOSE: To investigate the effect of the foveal Müller cell cone structure on the anatomical and functional response to intravitreal bevacizumab treatment in patients with diabetic macular edema. METHODS: In 93 treatment-naive eyes with center-involved cystic type diabetic macular edema, spectral-domain optical coherence tomography scans of baseline were retrospectively evaluated to determine the foveal Müller cell cone structure and prognostic features including length of disorganization in th
