The capabilities and precision of spectral-domain OCTs in today’s market are continuously advancing. Joining the line-up is a new high-resolution imaging system from Visionix, marketed as the Optovue Solix FullRange OCT. The company is also offering a second device called Optovue Solix Essential, which—aside from its inability to perform multimodal imaging—still shares many of the same features as the full-range model. 

The Solix OCT scans at an ultra-high speed of 120kHz, according to the company press release. Visionix notes that both devices feature company-designed software, coined “iWellness” and “AngioWellness,” that can be used to assess and monitor patients with diabetes or glaucoma suspects by combining structural data on retinal and ganglion cell thickness with objective metrics on retinal vasculature. The software also uses FAZ analytics to reveal early indicators of diabetes-related ocular changes.

Both the FullRange and Essential platforms can perform advanced glaucoma screening using technology such as AI segmentation. With the full-range system, the repeatability and reproducibility of glaucoma analytics are two times better than in the previous model, Visionix says. Both platforms also use pachymetry and epithelial thickness mapping to aid in the assessment of anterior pathologies such as keratoconus and dry eye, the press release notes.

The more feature-loaded of the two, Solix FullRange, can perform the following functions for anterior segment assessment, according to the device brochure:

  • Single-scan imaging for visualization of the entire anterior chamber from the front of the cornea to the anterior of the lens or entire crystalline lens.
  • Angle structure visualization and quantification.
  • A 10mm corneal layer map showing epithelial, stromal and total corneal thickness with change analysis.
  • External IR imaging to display the structure of the upper and lower lids.

As for the posterior segment, Visionix says that the FullRange platform features AngioVue OCT-A software for 3D visualization and quantification of retinal vasculature. A montage feature also enables widefield visualization of the peripheral retina. The company notes that the technology can allow for accurate retinal analysis even in highly myopic patients. 

For ODs who aren’t interested in multimodal imaging but still desire a fast and advanced OCT, the Solix Essential might be the better choice, as it includes the same anterior and posterior segment OCT and OCT-A capabilities.
