    1. Optical coherence tomography and color fundus photography in the screening of age-related macular degeneration: A comparative, population-based study

      Optical coherence tomography and color fundus photography in the screening of age-related macular degeneration: A comparative, population-based study

      Purpose To analyze the individual value and the contribution of color fundus photography (CFP) and optical coherence tomography (OCT) in the screening of age-related macular degeneration (AMD) of an unselected population. Methods CFP and OCT images of 15957 eyes of 8069 subjects older than 55 years, obtained during a population-based screening for AMD using a single diagnostic non-mydriatic imaging device, were analyzed by a blinded examiner. The two techniques were preliminary evaluated considering the dichotomous parameter "gradable/ungradable", then gradable images were classified. CFP were graded according to the standardized classification of AMD lesions. OCT images were also categorized considering ...

    4. Hyperreflective Intraretinal Foci as an OCT Biomarker of Retinal Inflammation in Diabetic Macular Edema

      Hyperreflective Intraretinal Foci as an OCT Biomarker of Retinal Inflammation in Diabetic Macular Edema

      We read with great interest the article titled “Association Between Soluble CD14 in the Aqueous Humor and Hyperreflective Foci on Optical Coherence Tomography in Patients with Diabetic Macular Edema” by Lee et al. 1 The authors investigated the expression of soluble CD14 (sCD14) in aqueous humor (AH) samples of patients with diabetic macular edema (DME), and the presence of hyperreflective foci (HF) on spectral-domain optical coherence tomography (SD-OCT) in these eyes. The authors found both higher levels of sCD14, and increased number of HF in the inner retina compared to controls, and concluded that, since sCD14 is released by retinal ...

    5. Early retinal and choroidal OCT and OCT angiography signs of inflammation after uncomplicated cataract surgery

      Early retinal and choroidal OCT and OCT angiography signs of inflammation after uncomplicated cataract surgery

      Purpose To evaluate, by means of optical coherence tomography (OCT) and OCT angiography (OCTA), early retinal, choroidal and macular perfusion changes induced by a local inflammatory reaction secondary to uncomplicated cataract surgery. Methods Selected eyes undergoing cataract surgery were enrolled in a prospective study. OCT and OCTA were performed before cataract surgery (T0) and at day: 1 (T1), 7 (T7), 30 (T30) and 90 (T90). Inner (IR) and outer retinal (OR) volumes, choroidal volume, hyper-reflective retinal spots (HRS) in IR and OR changes were measured at OCT. Macular perfusion was analysed in superficial (SCP), intermediate (ICP) and deep retinal capillary ...

    6. Early OCT angiography changes of type 1 CNV in exudative AMD treated with anti-VEGF

      Early OCT angiography changes of type 1 CNV in exudative AMD treated with anti-VEGF

      Aims To investigate, with optical coherence tomography angiography (OCTA), short-term changes of type 1 choroidal neovascularisation (CNV), secondary to exudative age-related macular degeneration, after anti-vascular endothelial growth factor (VEGF) treatment. Methods Patients affected by type 1 CNV treated with intravitreal anti-VEGF were consecutively enrolled. All patients underwent OCTA examination before and 48 hours after anti-VEGF treatment. Quantitative and qualitative vascular and morphological macular changes were evaluated. Results Sixteen eyes were included (11 treated with aflibercept and 5 with ranibizumab). Both CNV mean area and pigment epithelium detachment significantly reduced (p=0.0004 and p=0.0007, respectively) after treatment. Cystoid ...

    7. Peripapillary vascular changes in radiation optic neuropathy: an optical coherence tomography angiography grading

      Peripapillary vascular changes in radiation optic neuropathy: an optical coherence tomography angiography grading

      Aims To investigate peripapillary vascular changes secondary to radiation optic neuropathy (RON) using optical coherence tomography angiography (OCT-A) and to propose a clinical grading of RON based on OCT-A findings. Methods Thirty-four patients affected by RON were consecutively included. Each patient underwent best corrected visual acuity measurement (ETDRS score) and OCT-A (Nidek RS-3000 Advance device, Nidek, Gamagori, Japan). The radial peripapillary capillary plexus (RPCP) and the entire peripapillary capillary bed (EPCB) were analysed. Quantitative analysis of the OCT-A images was performed using open-source available ImageJ software (National Institutes of Health, Bethesda, Maryland, USA). Qualitative analysis based on the proposed clinical ...

    8. HYPERREFLECTIVE RETINAL SPOTS IN NORMAL AND DIABETIC EYES: B-Scan and En Face Spectral Domain Optical Coherence Tomography Evaluation

      HYPERREFLECTIVE RETINAL SPOTS IN NORMAL AND DIABETIC EYES: B-Scan and En Face Spectral Domain Optical Coherence Tomography Evaluation

      Purpose: To evaluate hyperreflective retinal spots (HRS), in normal subjects and diabetic patients without and with macular edema (diabetic macular edema, DME), on linear B-scans and corresponding en face image of spectral-domain optical coherence tomography. Methods: Retrospective evaluation of images of 54 eyes/subjects (16 normal subjects, 19 diabetic patients without DME, and 19 with DME). On horizontal B-scan spectral-domain optical coherence tomography, passing through the center of the fovea, the following characteristics of HRS were evaluated: location (inner retina or outer retina), size (<=30 or >30 [mu]m), reflectivity (similar to nerve fiber layer or to retinal pigment epithelium-Bruch ...

    9. Microperimetry Features of Geographic Atrophy Identified With En Face Optical Coherence Tomography

      Microperimetry Features of Geographic Atrophy Identified With En Face Optical Coherence Tomography

      Importance Progressive geographic atrophy (GA) of the retinal pigment epithelium leads to loss of central vision. To identify GA in age-related macular degeneration and assess treatment, correlation of function observed on microperimetry with structure observed on optical coherence tomographic (OCT) images may be of value. Objective To characterize the microperimetric function of GA as identified from en face OCT imaging. Design, Setting, and Participants In a case-series study, 20 patients (22 eyes) entered the study at the University of Padova according to preplanned conditions. From March 1 to July 30, 2014, en face OCT images were obtained at the outer ...

      Optical Coherence Tomography in the Diagnosis of Optic Pathway Gliomas

      Purpose: To compare visual function assessment, optic disc evaluation by indirect ophthalmoscopy and retinal nerve fibres layer analysis by optical coherence tomography (OCT) for the screening of optic pathway gliomas in paediatric patients (2-15 years) affected by neurofibromatosis type-1.
