Choroidal Thickening and Hyperpermeability Related to Choroidal Ischemia

ABSTRACT Purpose: Choroidal hyperpermeability was first described as a characteristic indocyanine green angiography (ICGA) finding seen in eyes with central serous chorioretinopathy and has been regarded as closely related to the pathophysiology of this entity. In the present study, the role of choroidal ischemia in producing ICGA choroidal hyperpermeability has been investigated in patients with hypertensive choroidopathy related to...

Spectral Domain Optical Coherence Tomography Findings in Patients with Macropsia

ABSTRACT Purpose: To evaluate the retinal morphologic characteristics of patients with macropsia caused by epiretinal membrane (ERM) based on spectral-domain optical coherence tomography (SD-OCT). Methods: A cross-sectional non-interventional study was performed to compare the characteristics of retinal structures in eyes with ERM according to the presence or absence of macropsia. Twenty-six patients with ERM and macropsia were defined as...

Multi Modal Imaging and Choroiditis

ABSTRACT Multi modal imaging techniques involving FA, SD-oct & EDI and ICG angiography accurately delineate the area of choroid/RPE involvement OCT Angiography also an imaging which helps to identify the choroidal hypo or non perfusion compared to retinal layers. AF is a non-invasive technique which helps us to monitor about the early recurrences and the dosing of corticosteroids and immunomodulators The multimodal approach also helps...

Reproducibility of Fixed-luminance and Multi-luminance Flicker Electroretinography in Patients with Diabetic Retinopathy Using an Office-based Paradigm

ABSTRACT Objective: Full-field electroretinography (ERG)is the only available technology to provide objective, quantifiable and global assessment of retinal function. Laboratory-based Flicker ERG has previously been described as a reliable tool in quantifying retinal dysfunction in diabetic retinopathy (DR). We evaluated the inter-session reproducibility of the office-based Diopsys NOVA Flicker ERG in patients with mild-to-moderate NPDR. We...

The Effects of Hydroxychloroquine Therapy on the Flow Area of Choriocapillaris Layer. An Optical Coherence Tomography Angiography Study

ABSTRACT Purpose: The aim of this study was to quantitatively compare the flow area of choriocapillaris layer in patients receiving from hydroxychloroquine (HCQ) therapy for more than 5 years with age and sex matched controls. Design: A prospective cross-sectional study. Methods: The patients taking HCQ who were screened for toxic effects were evaluated. All patients received a complete ophthalmic examination, including measurement of best...
