    1. EN FACE VERSUS 12-LINE RADIAL OPTICAL COHERENCE TOMOGRAPHY SCAN PATTERNS FOR DETECTION OF MACULAR FLUID IN NEOVASCULAR AGE-RELATED MACULAR DEGENERATION

      EN FACE VERSUS 12-LINE RADIAL OPTICAL COHERENCE TOMOGRAPHY SCAN PATTERNS FOR DETECTION OF MACULAR FLUID IN NEOVASCULAR AGE-RELATED MACULAR DEGENERATION

      Purpose: To compare fluid detection of autosegmented en face to 12-line radial spectral domain optical coherence tomography scan patterns in neovascular age-related macular degeneration. Methods: Retrospective observational case series. Sixty-seven patients (94 eyes) with neovascular age-related macular degeneration underwent autosegmented en face optical coherence tomography (with associated 304-line raster scan) and 12-line radial scan patterns. Sensitivity and specificity of fluid detection for en face scan and 12-line radial scans were determined by combining radial and 304-line raster scans as a gold standard. Results: Two hundred and fifty-eight en face and 12-line radial spectral domain optical coherence tomography scans were interpreted ...

    2. Quantification of Diabetic Macular Ischemia Using Optical Coherence Tomography Angiography and Its Relationship with Visual Acuity

      Quantification of Diabetic Macular Ischemia Using Optical Coherence Tomography Angiography and Its Relationship with Visual Acuity

      Purpose To quantify foveal avascular zone (FAZ) area and macular vascular density objectively using optical coherence tomography angiography (OCTA) and to examine correlations with visual acuity in eyes with diabetic retinopathy (DR) in the absence of diabetic macular edema. Design Retrospective observational case series. Participants Eighty-four eyes from 55 patients with DR and 34 control eyes from 27 age-matched healthy participants. Methods All eyes underwent OCTA (RTVue-XR Avanti; Optovue, Inc, Fremont, CA). Integrated automated algorithms were used to quantify FAZ area and macular vascular density. Main Outcome Measures FAZ area, vessel area density (VAD), vessel length density (VLD), and visual ...

    3. Optical coherence tomography angiography (OCT-A) of type 2 retinal arteriovenous malformation

      Optical coherence tomography angiography (OCT-A) of type 2 retinal arteriovenous malformation

      Retinal arteriovenous malformations (AVMs) are a rare congenital, nonhereditary vascular abnormality. They are typically unilateral and asymptomatic, ranging from a single arteriovenous communication to a complex anastomotic system. 1,2 The lesions most commonly involve the superotemporal arcade (41%), papillomacular bundle (34%), and optic disc (6%) 2,3 and are classified into 3 groups by Archer on the basis of capillary characteristics and systemic findings. 1 Characteristically, the lesions demonstrate rapid filling without capillary leakage on fluorescein angiography.

    4. Optical Coherence Tomography Angiography and En Face Optical Coherence Tomography Features of Paracentral Acute Middle Maculopathy

      Optical Coherence Tomography Angiography and En Face Optical Coherence Tomography Features of Paracentral Acute Middle Maculopathy

      Purpose To characterize the optical coherence tomography (OCT) angiography, en face OCT, and microperimetry features of paracentral acute middle maculopathy in both the acute phase and after resolution, and to propose a classification of distinct subtypes of this entity. Design Retrospective observational case series. Methods Clinical histories, high-resolution digital color imaging, spectral-domain OCT images, fluorescein angiography, OCT angiography images, and en face OCT images of 16 patients with paracentral acute middle maculopathy were evaluated. Microperimetry was available in 6 patients. Results The most common referring diagnoses were isolated branch retinal arterial occlusion (5/16), combined central retinal vein and cilioretinal ...

    5. Radial versus raster spectral-domain optical coherence tomography scan patterns for detection of macular fluid in neovascular age-related macular degeneration

      Radial versus raster spectral-domain optical coherence tomography scan patterns for detection of macular fluid in neovascular age-related macular degeneration

      Background/aims To compare the 12-line radial to the 25-line raster spectral-domain optical coherence tomography (SD-OCT) acquisition patterns at detecting intraretinal or subretinal fluid in eyes with neovascular age-related macular degeneration (AMD). Methods Retrospective cross-sectional analysis of 200 eyes with neovascular AMD. Sequential 12-line radial and 25-line raster scans were evaluated for the presence of intraretinal/subretinal fluid. Results A total of 394 SD-OCT scans were interpreted (1.97 scans per eye). The 12-line radial detected intraretinal/subretinal fluid in all but 7 of 394 scans (1.7%; 95% CI 0.7% to 3.6%), resulting in a sensitivity of ...

    6. Enhanced depth imaging optical coherence tomography of precursor cell leukemic choroidopathy before and after chemotherapy

      Enhanced depth imaging optical coherence tomography of precursor cell leukemic choroidopathy before and after chemotherapy

      Serous retinal detachment (SRD) can be the initial manifestation of leukemia. Herein, we explore the retinal and choroidal features on enhanced depth imaging optical coherence tomography (EDI-OCT) of SRD in a patient with undiagnosed leukemia. A 23-year-old male developed blurred visual acuity of 20/200 in the right eye oculus dexter (OD) and 20/200 in the left eye oculus sinister (OS). Funduscopically, he manifested serous macular detachment in both eyes oculi uterque (OU) without hemorrhagic retinal abnormalities. EDI-OCT disclosed macular detachment OU and homogeneous, marked choroidal opacification with thickening to 724 ΅m OD and estimated >600 ΅m OS and ...

    7. Radial versus raster spectral-domain optical coherence tomography scan patterns for detection of macular pathology

      Radial versus raster spectral-domain optical coherence tomography scan patterns for detection of macular pathology

      Purpose To compare the 6-line radial versus the 25-line raster spectral-domain optical coherence tomography (SD-OCT) acquisition patterns at detecting intraretinal fluid, subretinal fluid, vitreomacular traction, and full-thickness macular hole (MH). Design Retrospective cross-sectional analysis. Methods Series of 365 eyes with neovascular age-related macular degeneration (AMD), diabetic macular edema (DME), central and branch retinal vein occlusion (CRVO/BRVO), central serous chorioretinopathy, vitreomacular traction, and full-thickness MH. Sequential 6-line radial and 25-line raster scans were evaluated for intraretinal/subretinal fluid and when applicable, vitreomacular traction and MH. Results For neovascular AMD (133 scans), seven 25-line raster scans confirmed subretinal/intraretinal fluid not ...

    8. Spectral Domain Optical Coherence Tomographic Findings of Occult Macular Dystrophy

      Occult macular dystrophy is a rare macular disorder in which patients have bilaterally decreased visual acuity without any significant ophthalmoscopic findings. Using spectral domain optical coherence tomography, the authors found a defect in the junction between the inner and outer segments of the foveal photoreceptors in a patient with occult macular dystrophy. [Ophthalmic Surg Lasers Imaging 2008;39:S114-S116.]
