Ophthalmology optical coherence tomography scanner mocean4000

The vascular imaging technology (OCTA) based on optical coherence tomography is a non-invasive and fast blood flow detection technology. Currently, it is mainly used for blood flow imaging of the retinal choroid. OCTA can detect and quantitatively analyze blood flow signals without intravenous injection of contrast agent, and can observe and judge the changes in blood flow of the retinal choroid in layers. High-speed imaging, large scanning range, powerful functions and glaucoma analysis functions

Product Advantages

2. Large-scale real-time SLO fundus imaging,

Real-time eye tracking Mocean 4000 can acquire 47 large-scale fundus images and high-definition OCT images in real time, and the lesion area can be easily found before acquisition. The average superposition of 50 SLO fundus images provides high-definition fundus images with enhanced signal-to-noise ratio and clearer imaging. SLO-based eye tracking can reduce artifacts caused by eye drift and micro saccades. It performs 100 tracking per second, with a tracking accuracy of 10 microns and a success rate of more than 95%, which is an ideal solution for patients with less cooperation

3. Quantitative analysis of the new school network

Macular area: blood vessel density perfusion density / FAZ / non-perfusion area / blood flow area optic disc area vascular density perfusion density

4. 16mm wide-range angle scan and data analysis

5. Analysis of upper corneal thickness

Mocean 4000 provides a 6mm corneal epithelial thickness map, which is an important part of refractive surgery diagnosis and has important clinical application value
