Sensitivity and specificity of detecting polypoidal choroidal vasculopathy with en face optical coherence tomography and optical coherence tomography angiography

Conclusion: Sensitivity of detecting PCV was low using structural en face OCT and OCTA but specificity was high. Indocyanine green angiography remains the gold standard for PCV detection.

Raghu, C.N. ManjunathAbstractA dual left anterior descending (LAD) coronary artery is a rare, and benign congenital anomaly. In this anomaly, there is the presence of two LADs in the anterior inter ventricular sulcus (AIVS). One of the LADs is a short one that ends high in the AIVS. The other longer one enters the distal AIVS and feeds the apex. To date, 9 types of dual LAD variants, and one novel type X has been reported. Here...

Conclusion: When used as a first diagnostic test, SD-OCT combined with CFP had sensitivity and specificity similar to those of FA combined with CFP, for the diagnosis of CNV in age-related macular degeneration. This shows the increasingly important role of SD-OCT as a first-line test in the diagnosis of CNV.

Conclusion: There was no significant difference in the size of the CNV lesion as measured on either commercially available spectral domain OCTA device. Both devices were comparable in their detection of CNV lesions on manual adjustment of segmentation lines. However, their automated segmentation algorithms need improvement to allow for accurate measurement of CNV lesions for routine clinical application.

Conclusion: Optical coherence tomography angiography is a noninvasive imaging modality allowing a good visualization of both branching vascular network and polyp dilations. Our findings suggest that OCTA is a useful tool in the investigation of chronic central serous chorioretinopathy complicated by polypoidal choroidal vasculopathy.

Purpose: To quantify retinal microvascular alterations using optical coherence tomography angiography in diabetic patients, and to evaluate the accuracy of decreased vessel density (VD) in predicting early diabetic retinopathy (DR). Methods: One hundred and two eyes of 51 diabetic patients and 92 eyes of 46 individuals without diabetes were examined. Duration of diabetes, insulin therapy, blood pressure, HbA1C, dyslipidemia, axial length, and the presence of DR were recorded. Retinal VD was measured using optical coherence tomography angiography. The effect of risk factors on VD and on DR was assessed using multivaria...

Conclusion: Choriocapillaris flow impairment was observed in many highly myopic eyes, even in those with mild fundus changes, and worsened with increasing severity of myopic maculopathy. Longitudinal studies are needed to assess whether CC flow impairment predicts the risk of myopic maculopathy progression.

Purpose: To assess foveal and parafoveal vasculature at the superficial capillary plexus, deep capillary plexus, and choriocapillaris of patients with X-linked retinoschisis by means of optical coherence tomography angiography. Methods: Six patients with X-linked retinoschisis (12 eyes) and seven healthy controls (14 eyes) were recruited and underwent complete ophthalmologic examination, including best-corrected visual acuity, dilated fundoscopy, and 3 × 3-mm optical coherence tomography angiography macular scans (DRI OCT Triton; Topcon Corp). After segmentation and quality review, optical coherence tomography a...
