    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.

    3. Optical coherence tomography angiography in optic nerve sheath meningioma

      Optical coherence tomography angiography in optic nerve sheath meningioma

      This study describes Spectral Domain-Optical Coherence Tomography (SD-OCT) and Optical Coherence Tomography Angiography (OCTA) features of Optic Nerve Sheath Meningioma (ONSM). A 22-year-old woman, diagnosed with meningiom encircling the right optic nerve inside the intraorbital segment optic canal at the magnetic resonance imaging, showed a normal fundus examination. Instead, SD-OCT and OCTA revealed alterations in the neurostructure and microvascular network of the optic nerve. Despite fundoscopy and fluorescein angiography, SD-OCT and OCTA represent valid, non-invasive and reliable methods to evaluate neurostructural and vascular irregularities in this benign tumor of the optic nerve.

    4. Optical Coherence Tomography Angiography Findings in Fabry Disease

      Optical Coherence Tomography Angiography Findings in Fabry Disease

      Background: Fabry disease (FD) is a X-linked recessive lysosomal storage disorder characterized by altered biodegradation of glycosphingolipids. It is a multisystem pathology, also involving ophthalmological systems that show modifications of the vessel wall due to glycosphingolipid deposits. Optical coherence tomography angiography (OCT-A) allows for an objective analysis of retinal microvasculature alterations, evaluating retinal vessel density in macular region. Methods: A total of 54 FD patients (34 females, 20 males, mean age 44.1 ± 15.6 years) and 70 controls (36 females, 34 males, mean age 42.3 ± 15.6 years) were included in this study.

    8. Optical coherence tomography angiography in retinal cavernous hemangioma

      Optical coherence tomography angiography in retinal cavernous hemangioma

      Cavernous hemangiomas of the retina are rare benign vascular tumors, commonly diagnosed in children and young adults. They are characterized by dilated blood vessels that form cavities or caverns through which the blood flow is very low or virtually absent [1] . Retinal lesions may be associated with cerebral hemangiomas [1] , which conversely, do not harbor any tissue within the malformation, the smooth muscle is impaired and there is no capsule surrounding the caverns. Cavernous hemangioma has also been associated with choroidal hemangioma [2] and ocular melanocytosis [3] . Retinal lesions vary in size and location, and generally follow the course of ...

      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 ...
