Enhancement of Choriocapillaris Visualization in En Face Swept-Source Optical Coherence Tomography Angiography Images
BACKGROUND Visualization of the choriocapillaris vessels using swept-source optical coherence tomography is a novel technique. However, en face images obtained with current commercial equipment using this method are still unclear. Therefore, using freely available image processing software, we have been able to enhance and clearly visualize single choriocapillaris blood vessels. MATERIAL AND ME...
متن کاملOptical Coherence Tomography Angiography to Estimate Retinal Blood Flow in Eyes with Retinitis Pigmentosa
Ophthalmologists sometimes face difficulties in identifying the origin of visual acuity (VA) loss in a retinitis pigmentosa (RP) patient, particularly before cataract surgery: cataract or the retinal disease state. Therefore, it is important to identify the significant factors correlating with VA. Nowadays, retinal blood flow in superficial and deep layers can be estimated non-invasively using ...
متن کاملMultimodal imaging of hypertensive chorioretinopathy by swept-source optical coherence tomography and optical coherence tomography angiography
RATIONALE To investigate malignant hypertension ocular lesions with swept source optical coherence tomography (SS-OCT) and optical coherence tomography angiography (OCT-A). PATIENT CONCERNS Visual loss due to malignant hypertension. DIAGNOSES Hypertensive chorioretinopathy. INTERVENTIONS Patients were thoroughly examined on presentation and 30 days after their first visit, with swept-sour...
متن کاملQuantification of Macular Microvascular Changes in Patients With Retinitis Pigmentosa Using Optical Coherence Tomography Angiography.
Purpose To evaluate the microvascular changes in eyes with RP quantitatively using optical coherence tomography angiography (OCTA) and to determine whether the correlations between these indices and the severity of RP are significant. Methods This was a retrospective, observational study. The medical records of 53 RP patients and 46 controls were reviewed. The OCTA images were obtained with t...
متن کاملWide field and highly sensitive angiography based on optical coherence tomography with akinetic swept source.
Wide-field vascular visualization in bulk tissue that is of uneven surface is challenging due to the relatively short ranging distance and significant sensitivity fall-off for most current optical coherence tomography angiography (OCTA) systems. We report a long ranging and ultra-wide-field OCTA (UW-OCTA) system based on an akinetic swept laser. The narrow instantaneous linewidth of the swept s...
