“…Modern in vivo investigations by OCT and HRT generated novel images of the structural changes in racemose haemangioma. Our conventional OCT images demonstrated agreement with other reports that the blood in the large vessels was highly backscattered in bright red and white colours because the OCT beam is rapidly attenuated, thus retinal structures underneath the vessel are shadowed (Jager et al. 2005; Materin et al.…”

ABSTRACT.Purpose: To determine the vascular morphology of racemose haemangioma and related functional alterations in arteriovenous (AV) malformation type 3. Methods: A 17-year-old patient with unilateral racemose haemangioma received a full ophthalmic examination including Snellen visual acuity (VA) and Goldmann visual field. The central vision was investigated by scanning laser ophthalmoscope (SLO) and multifocal electroretinogram (mfERG). The ocular haemodynamics were examined by fluorescence angiography and Doppler ultrasound. The tomographic contour of the vascular architecture was visualized using B-scan ultrasound, Stratus optical coherence tomography (OCT) and three-dimensional Heidelberg retina tomograph (3D-HRT II). Results: The VA of the patient's right eye was reduced to 20 ⁄ 400 and her visual field was constricted concentrically. Microperimetry revealed a small central field with good central fixation. The mfERG demonstrated reduced amplitudes of the central retina. On fluorescein angiography, there was a fast filling of the retinal branches related to the racemose vessels. Doppler ultrasound confirmed a significantly changed haemodynamic flow in the racemose vessels. Ultrasound, OCT and HRT demonstrated a prominent optic nerve head. Conclusion: The racemose haemangioma led to a marked visual field defect. Racemose haemangiomas are associated with severe changes in the haemodynamics of the retinal vasculature.

“…Furthermore, they are responsible for the perfusion of a larger area of retinal tissue than traditional retinal vessels. 8 These congenital retinal macrovessels may be associated with ischemia, leakage, preretinal neovascularization following thrombotic occlusion. 4 We did not see these findings with our report, nor did two previous published cases of choroidal macrovessels describe these findings.…”

Purpose To report a case of a choroidal macrovessel imaged using enhanced-depth imaging spectral domain optical coherence tomorgraphy (EDI SD-OCT) and describe the choroidal features. Methods Case report. A 42-year-old man presented with metamorphopsia. Multimodal imaging, including color fundus photography, near infrared reflectance (NIR), and EDI-OCT was used to describe a choroidal macrovessel. Results Initial ophthalmic examination revealed a serpentine-shaped subretinal pattern deep to the retina near the fovea. When the color image was subjected to a red-filter, a large diameter vessel could be seen coursing from the fovea to the temporal macula. EDI-OCT of the choroidal macrovessel revealed a thickened choroid, and mild deformation of both the ellipsoid zone and the choroidal-scleral junction. En face SD-OCT at the level of the choroid demonstrated the anomalous vessel. Conclusions EDI-OCT and en face OCT, used in conjunction with other imaging modalities, can be used to demonstrate the presence and pattern of a choroidal macrovessel. A thickened choroid and overlying outer retinal indentation was observed in association of the choroidal macrovessel. These imaging tools can help distinguish this condition from other diagnoses with a similar appearance, such as ophthalmomyiasis.
