Retinal imaging with en face and cross-sectional optical coherence tomography delineates outer retinal changes in cancer-associated retinopathy secondary to Merkel cell carcinoma.

Background: The study aims to correlate Fourier-domain optical coherence tomography (FD-OCT) with Goldmann visual field (GVF) to show the photoreceptor (PR) structure and function relationship in the first described case of cancer-associated retinopathy (CAR) from Merkel cell carcinoma.

Findings: A case study of a patient with CAR who was imaged with serial GVF and FD-OCT over a 2-year period was carried out. En face images were created using a custom algorithm from the volumetric Fourier-domain OCT scans at the PR level.

Infectious crystalline keratopathy predominantly affecting the posterior cornea.

A case of infectious crystalline keratopathy that affects mainly the posterior stroma is presented. Crystalline infiltrates presented after multiple epithelial defects and chronic topical steroid use following a penetrating keratoplasty in this patient. His epithelial defects persisted and given the deep location of the crystalline infiltrates, a penetrating keratoplasty was performed again.

Comparison of optic disc parameters measured by RTVue-100 FDOCT versus HRT-II.

Purpose: To compare optic disc measurements between the new Fourier-domain optical coherence tomography (RTVue-100) and the confocal scanning laser ophthalmoscopy (Heidelberg retinal tomography, HRT-II) in clinical practice.

Methods: Patients seen from the glaucoma service of an academic department of ophthalmology between August 2008 to August 2009 with good-quality RTVue-100 and HRT-II images within 6 months of each other were included (363 patients were included, 1 eye from each patient). The rim of the optic disc was drawn automatically by RTVue-100 and manually by a single experienced observer for HRT-II.

Optic disc parameters from optovue optical coherence tomography: comparison of manual versus automated disc rim determination.

Purpose: To compare optic disc parameters when using manual disc detection versus automated software on RTVue-100 Fourier-domain optical coherence tomography.

Methods: Nonrandomized comparative study using images obtained from a tertiary-care Glaucoma Clinic from August, 2008 to May, 2009. Four hundred thirty-four patients with mean age of 67.
