Xephilio OCT-A1

Features

Fast and Easy Acquisition with Incredible Detail

With a digital resolution of up to 1.6μm, the system enables excellent differentiation of structures and individual layers of the retina. High scanning speed of 70,000 A-scans/s enables very short examination times of usually about two seconds, resulting in less motion artefacts and increased patient comfort.

Flow Fusion Technology and Deep Learning Technology Intelligent Denoise

Flow Fusion and the new AI-based Intelligent Denoise option can further improve the clinical outcomes of OCTA studies. These tools greatly enhance workflow and diagnostic confidence, providing excellent patient comfort and well-being.

Angio Expert HD Software

Angio Expert HD not only offers a wide range of advanced image quality tools, but also adds advanced OCTA analysis to the imaging portfolio. Angio Expert HD provides high pixel density and extended field of view, enabling the imaging of vessels and capillaries over a large area with high precision.

Clinical Cases

With the Canon OCT-A1 the individual layers of the retina can be clearly defined.

61-year-old male patient with recently diagnosed type 2 diabetes. Visual acuity was reduced to 0.32 in the right eye as compared to 1.0 in the left eye. On the scan, a small intraretinal accumulation of fluid can be seen to the right of the fovea. White dots in the fluid accumulation are hard exudates.

78-year-old female patient. Accumulation of a solid material is seen in the subretinal space, RPE. The condition is a genetic macular dystrophy characterized by mild visual impairment and metamorphosia. Typical age of onset is between the fourth and sixth decade. It may progress to choroidal neovascularization and atrophy. A typical finding is attachment of the posterior hyaloid to the macular region, presumably secondary to the macular dystrophy.

87-year-old female patient. A macular hole affects all retinal layers. The intraretinal edema at the edges of the hole is a very typical finding. Furthermore, a slight elevation of the retina is seen. There is no loss of retinal tissue, but because of intrinsic pulling forces, the edges of the hole have been pulled away from each other. Treatment is surgery with vitrectomy, inner limiting membrane peeling and injection of air or gas.

61-year-old male patient with sudden onset of metamorphopsia. OCT imaging shows a pigment epithelial detachment (PED) just temporal to the fovea, with subretinal fluid on the shoulders of the PED. Fluorescein angiography revealed increasing hyperfluorescence in the later phases, in accordance with the presence of an occult choroidal neovascular membrane, treatment with ranibizumab was initiated.

75-year-old female patient has reading difficulties and problems with judging distances. A pronounced thickening of the central retina can be seen (466μm). The retinal surface is wrinkled due to the fibrosis and shrinking of the membrane. Treatment is vitrectomy and inner limiting membrane peeling.

74-year-old male patient, experiences a gradually expanding grey area in his left central vision. He is known to have a pigment epithelial detachment in his left eye. On this scan, the pre-existing pigment epithelial detachment (PED) is seen. However, overlying the PED, a cystoid macular edema caused by a venous thrombosis is evident.

31-year-old female patient, pregnant in third trimester, suddenly experienced a blurred spot in her central vison. On OCT, an accumulation of fluid is seen under the retina in the space between the photoreceptors and the retinal pigment epithelium (RPE). However, within that same area a small detachment of the RPE can be seen as well, and an adjacent small fluid accumulation is seen to the left. There is no treatment, and the condition usually resolves spontaneously over 3-6 months. Observation and reassurance.
