Purpose: To report the clinical presentation, multimodal imaging, and management of a patient with metastatic melanoma who presented with cystoid macular edema (CME). Observations: We report a case of a 71-year-old Caucasian male with metastatic melanoma who presented with bilateral cystoid macular edema after being on treatment with a programmed T cell death ligand 1 inhibitor, MPDL3280, for 1 year. Multimodal imaging techniques, including color fundus photographs, autofluorescence, spectral domain optical coherence tomography (OCT), fluorescein angiography (Spectralis, Heidelberg, Germany), and spectral-domain OCT angiography (Zeiss; California, USA) were performed to evaluate the etiology of his CME and to monitor his response to treatment...

PURPOSE: To evaluate the distribution of peripapillary retinal nerve fiber layer thickness as measured by optical coherence tomography and its associations with ocular parameters in a population-based setting. METHODS: In the population-based Gutenberg Health Study, 1974 subjects from the Mainz-Bingen region were scheduled for ophthalmologic examinations, including visual acuity, refraction, tonometry, biometry, and measurements of peripapillary retinal nerve fiber layer thickness (pRNFL) by optical coherence tomography (SD-OCT, Spectralis®, Heidelberg Engineering, Germany)...

PURPOSE: To investigate the thickness of retinal layers and association with final visual acuity using spectral-domain optical coherence tomography (SD-OCT) in macular area of macula-off rhegmatogenous retinal detachment (RRD) patients after a successful macular re-attachment. METHODS: In retrospective study, a total 24 eyes with macula-off RRD were enrolled. All patients underwent vitrectomy to repair RRD. Outer plexiform layer (OPL), outer nuclear layer (ONL), photoreceptor layer (PR), retinal pigment epithelium (RPE) thicknesses were measured by the Spectralis (Heidelberg Engineering, Heidelberg, Germany) SD-OCT with automated segmentation software...

Purpose This study demonstrates a standardized approach to measuring retinal thickness (RT) using spectral domain optical coherence tomography (SD-OCT) in commonly used animal models of disease and reports a normative data set for future use. Materials and Methods Twenty normal eyes of 4 adult animal models (5 rats, 5 rabbits, 5 canines, and 5 mini-pigs) were used. Manual measurements were made on the commercially available Heidelberg Spectralis™ SD-OCT to determine the total, inner, and outer retinal thickness (RT) at fixed distances from the optic nerve head (ONH) (1, 2, 3, 4, 5, and 6 mm away) in order to control for normal variation in retinal thickness...

PURPOSE: To determine whether microperimetry or optical coherence tomography (OCT) imaging can detect early disease in the fellow eye of patients with unilateral focal ischaemic glaucoma. METHODS: Thirty-seven consecutive adult patients with unilateral focal ischaemic glaucoma with a unilateral split-fixation visual field defect on standard automated perimetry (SAP) with normal SAP in the fellow eye were selected. All patients underwent microperimetry (MAIA, CenterVue, Italy) of the central 10 degrees and OCT imaging (Spectralis, Heidelberg Engineering, Germany) of the retinal nerve fibre layer of both eyes...

PURPOSE: Optical coherence tomography (OCT) enface visualisation of the retinal nerve fibre layer (RNFL) reflectance has been found to have some advantages over retinal thickness measures. However, it is not yet clear how abnormalities on enface images relate to findings of abnormalities from other clinical measures such as the circumpapillary retinal nerve fibre layer thickness (cRNFLT). We developed a technique to analyse the RNFL reflectance on the OCT enface images, and to investigate its relation with the cRNFLT...
