    1. Optical coherence tomography angiography in contractile morning glory syndrome

      Optical coherence tomography angiography in contractile morning glory syndrome

      This study describes the optical coherence tomography and optical coherence tomography angiography features of three eyes of three patients affected by contractile morning glory syndrome. Optical coherence tomography angiography scans of the peripapillary retina revealed a dense microvascular network without any vascular difference between the superficial vascular plexus and the deep vascular plexus around the optic nerve. These optical coherence tomography angiography findings confirm that the contractile movement could be due to the presence of an autonomic cholinergic muscular mechanism in the posterior part of the globe. In fact in our cases, the contractile movement seemed to be induced by ...

    2. Optical Coherence Tomography Angiography to Assess Vascular Remodeling of the Choriocapillaris After Low-Fluence Photodynamic Therapy for Chronic Central Serous Chorioretinopathy

      Optical Coherence Tomography Angiography to Assess Vascular Remodeling of the Choriocapillaris After Low-Fluence Photodynamic Therapy for Chronic Central Serous Chorioretinopathy

      Background To evaluate the efficacy of optical coherence tomography angiography (OCTA) in identifying changes in the choriocapillaris layer after low-fluence verteporfin photodynamic therapy (vPDT) in patients affected by chronic central serous chorioretinopathy (CSCR). Methods Low-fluence vPDT was performed on 28 eyes of 27 patients with CSCR. All patients underwent the following tests at baseline and 6 months after treatment: best corrected visual acuity (BCVA), fluorescein angiography, indocyanine green angiography, enhanced depth imaging OCT and OCTA. Results Subretinal fluid was completely absorbed in 18 of the 28 affected eyes (64.3%) after low-fluence vPDT (“responders”), and incompletely absorbed in 10 eyes ...

    3. Anterior-Segment Optical Coherence Tomography and Scanning Electron Microscopy to Evaluate Corneal Epithelial Changes in Patients Undergoing Glaucoma Therapy

      Anterior-Segment Optical Coherence Tomography and Scanning Electron Microscopy to Evaluate Corneal Epithelial Changes in Patients Undergoing Glaucoma Therapy

      Purpose: To measure corneal epithelial thickness (CET) in patients with glaucoma using anterior-segment optical coherence tomography and to evaluate CET changes in relation to corneal epithelial microvilli analyzed by scanning electron microscopy (SEM). Methods: Twenty-two eyes (16 patients) being treated with preservative-containing topical medications and 12 normal eyes underwent anterior-segment optical coherence tomography imaging using RTVue-100. The CET maps generated corresponded to a 6-mm diameter area of cornea that was divided into 17 sectors. We compared the CETs of each sector obtained in the glaucomatous group with those obtained in the control group. Results: Glaucomatous eyes were divided into 2 ...

    4. Evaluation of vascular changes with optical coherence tomography angiography after ruthenium-106 brachytherapy of circumscribed choroidal hemangioma

      Evaluation of vascular changes with optical coherence tomography angiography after ruthenium-106 brachytherapy of circumscribed choroidal hemangioma

      Purpose To describe the vascular changes of circumscribed choroidal hemangioma (CCH) after ruthenium-106 brachytherapy using optical coherence tomography angiography (angio-OCT). Methods Seven eyes of 7 patients diagnosed with symptomatic CCH who underwent ruthenium-106 plaque radiotherapy were included in the study. Patients underwent complete ophthalmic examination, bulbar echography and angio-OCT. The same protocol was applied 1 year after ruthenium-106 brachytherapy. Results At baseline, the mean best-corrected visual acuity (BCVA) in affected eyes was 0.67 ± 0.14 logMAR, and the mean tumor thickness was 4.46 ± 0.91 mm measured by standardized A-scan echography. After ruthenium-106 plaque treatment, the mean BCVA ...

    5. Optical coherence tomography angiography in pre-perimetric open-angle glaucoma

      Optical coherence tomography angiography in pre-perimetric open-angle glaucoma

      Purpose To evaluate the diagnostic efficacy of optical coherence tomography (OCT) angiography, in patients with pre-perimetric open-angle glaucoma. Methods Thirty-eight consecutive eyes of 26 patients with pre-perimetric open-angle glaucoma and 48 normal eyes of 32 controls were included in this prospective study. We evaluated OCT angiography, spectral-domain OCT and visual fields parameters. Differences between controls and patients and between OCT angiography parameters and traditional glaucoma measurements were evaluated. Receiver operating characteristic curves for OCT angiography parameters were assessed. Results The flow index ( p = 0.021) and vessel density ( p = 0.001) were significantly lower in pre-perimetric glaucoma eyes versus normal ...

    6. Optical coherence tomography angiography in incomplete acute Vogt-Koyanagi-Harada disease

      Optical coherence tomography angiography in incomplete acute Vogt-Koyanagi-Harada disease

      Dear Editor, Vogt-Koyanagi-Harada (VKH) disease is a cell-mediated autoimmune syndrome directed against melanocytes. It is considered a multisystem disorder characterized by granulomatous panuveitis often associated with neurologic and cutaneous manifestations. The choroid is the main site of autoimmune inflammation in ocular tissues[1]. Here we report the case of a 48-year-old woman with diminished vision that began about 15d earlier. The patient has consented to the submission of this Letter for submission to the journal. Her visual acuity was 0.8 in both eyes. She also suffered from headache and hearing loss, and reported a bout of influenza some days ...

    7. Study of the Radial Peripapillary Capillary Network in Congenital Optic Disc Anomalies with Optical Coherence Tomography Angiography

      Study of the Radial Peripapillary Capillary Network in Congenital Optic Disc Anomalies with Optical Coherence Tomography Angiography

      Abstract Purpose To evaluate the radial peripapillary capillary network with optical coherence tomography angiography (angio-OCT) in morning glory syndrome (MGS), optic disc colobomas and optic disc pits, and to explore possible correlations between the neural vascular structure and the pathogenesis of congenital optic disc anomalies. Design Prospective observational comparative case series. Methods Fifteen eyes of 15 patients with congenital optic disc anomalies were enrolled in this study. All patients underwent angio-OCT. The scans were centered on optic discs. Results The mean age at presentation was 33 years (range: 19–50 years). Congenital optic disc anomalies were identified in all 15 ...

    8. Choroidal Thickness in Open-Angle Glaucoma Measured by Spectral-Domain Scanning Laser Ophthalmoscopy/Optical Coherence Tomography

      Choroidal Thickness in Open-Angle Glaucoma Measured by Spectral-Domain Scanning Laser Ophthalmoscopy/Optical Coherence Tomography

      Aims: To measure macular choroidal thickness in healthy and glaucomatous eyes using spectral-domain scanning laser ophthalmoscopy/optical coherence tomography. Methods: Choroidal thickness was measured in 21 healthy eyes and 16 glaucomatous eyes. Choroidal thickness was measured under the fovea and at 500-µm intervals from the foveal center to 4 mm in the nasal and temporal directions. Vessels were counted in a macular area of 8,000 µm2. Only choroidal vessels with a horizontal diameter of at least 155 µm and a vertical diameter of at least 50 µm were considered. Results: The mean choroidal thickness was greatest below the fovea ...

    10. Evaluation of Posterior Pole with Echography and Optical Coherence Tomography in Patients with Behçet's Disease

      Background: In Behçet's disease posterior segment involvement is very frequent (about 80%). Macular edema is the most commonly observed complication and is related to reduction of visual acuity. The purpose of the study was to evaluate choroidal involvement during posterior vasculitis due to Behçet's disease. Methods: Thirty eyes (15 patients) presenting with posterior vasculitis due to Behçet's disease were studied. All patients had been evaluated with optical coherence tomography (Stratus OCT, Zeiss) to evaluate the retinal thickness (RT) and with standardized 8-MHz A scan echography to determine the retinochoroidal thickness (RCT). Echographic evaluation with 10- and 20-MHz ...
