Ellipsoid Zone Mapping Parameters In Retinal Venous Occlusive Disease With Associated Macular Edema.

Purpose: To evaluate the association of baseline ellipsoid zone (EZ) parameters on optical coherence tomography (OCT) as calculated by a semi-automated computer algorithm with baseline visual acuity in eyes with retinal vein occlusion (RVO).

Design: Retrospective consecutive case series.

Subjects: Patients affected by RVO presenting from January 2011 to December 2014.

Quantitative assessment of outer retinal layers and ellipsoid zone mapping in hydroxychloroquine retinopathy.

Background: To quantitatively assess outer retinal layers in eyes with hydroxychloroquine (HCQ) toxicity.

Methods: A retrospective case-control study was performed to identify eyes with HCQ retinopathy/toxicity at Cleveland Clinic. A clinical diagnosis of HCQ retinopathy was made based on clinical and imaging features including the presence of parafoveal ellipsoid zone (EZ) loss on spectral-domain optical coherence tomography (OCT) and visual field defects.
