Introduction:The use of OCT angiography for the analysis of neovessels of the ocular surface is currently at the experimental stage. Through this work we evaluate the benefits of OCTA in the detection of corneal neovessels, their depth and surface, the signs suggestive of activity / quiescence in comparison to fluorescein angiography. Materials And Methods:10 patients (10 eyes) with corneal neovessels (CNV) were prospectively recruited to Ophthalmology B at the Rabat Specialty Hospital between June and September 2019. All patients received OCT A fluorescein angiography (AF) at two-week intervals. Results:The results of the OCT A matched the AF data by showing immature neovessel (NV) characteristics for the early-diffusing NVs, allowing the study of the structure : trunk, numbers of segments, and fractal divisions, the existence of apical loop. As well as the detection of the flow level, exudative phenomena and associated lesions in high resolution OCT B. Discussion:Few studies have evaluated the OCTA in the evaluation of NVC, the published articles analyze the feasibility and reproducibility of this technique. Our initial analyzes suggest that scans provide better penetration and resolution of NVCs, but this requires direct comparative studies between OCTA systems used to scan the same eyes. The learning curve seemed fast for this technique. Conclusion :The evaluation of antiangiogenic treatments and the risk of graft rejection, it should be noted when interpreting OCTA scans of the anterior segment that artifacts may appear in dense scars areas in addition to motion artifacts.Future software enhancements and optimization for anterior segment acquisition may reduce these artifacts even more and improve the resolution of the image.

ABSTRACT Complex congenital heart diseases (CHD) often present as multiple cardiac lesions. The presence of one anomaly should stimulate the physician to perform a comprehensive assessment and look for other associated anomalies.1 Multimodal imaging may be necessary to diagnose such associated lesions as single imaging may occasionally miss them. Transthoracic echocardiography (TTE) and transesophageal echocardiography (TEE) are complimentary to each other. Routine use of TEE during intraoperative period may help us to refine diagnosis, detect the missing components and guide effective surgical repair. We present one such case where diagnosis and management were optimized by multimodal imaging. How to cite this article Kumar B, Madhavan JS, Puri GD, Rana SS.

Aim: To describe the multimodal imaging findings of pigmented paravenous retinochoroidal atrophy. Methods: A 23-year-old female presented to us for a routine ocular examination. She had a best-corrected visual acuity of 6/6 in both eyes. Anterior segment examination was unremarkable. Fundus examination showed pigmentary changes along the retinal vasculature extending from mid periphery to post-equatorial retina suggesting a diagnosis of pigmented paravenous retinochoroidal atrophy. Swept-source optical coherence tomography of the macula showed choriocapillaris thinning at the mid periphery whereas coherence tomography angiography at the mid periphery showed a relatively normal choriocapillaris vasculature in the early stage of the disease. Conclusion: A relatively normal choriocapillaris structure was seen on ocular coherence tomography angiography which could have been due to a milder form of the disease in a young patient.

A case of retinal arterial macroaneurysm (RAM) is presented with multimodal imaging, including commercially available optical coherence tomography angiography (OCT-A). Following treatment with intravitreal bevacizumab, reduction of flow signal through the RAM is documented. OCT-A provides useful information for the diagnosis and management of at least some patients with RAM, without the need for traditional fluorescein angiography.
