Visionstar OSE-2800

Spectral Domain Methodology

The methodology is listed as spectral domain, working from an optical source with a light centre wavelength of 840nm. A-scan depth is given as 3mm, which sets how far into the tissue each layered image extends.

Five Micron Optical Axial Resolution

Axial resolution is stated at 5 microns optical and 3.6 microns digital, with transverse resolution at 15 microns optical and 3 microns digital. Those figures govern how finely separate tissue layers can be told apart.

Two Glaucoma Cube Patterns

The data describes a glaucoma cube over the macular area and a second over the disc area. Sampling is evenly distributed across 200 by 200 A-scans, which the manufacturer relates to early detection.

Dense Retinal Thickness Cube

Retinal thickness is assessed point by point across a dense 500 by 100 cube. That density supports the thickness maps and progression comparisons clinicians rely on when following a patient over years.

Anterior Segment Line Scanning

The data lists an HD line scan at 6 or 16 mm and a 6-line radial scan for the anterior segment. Corneal imaging at this definition locates Bowman's layer, between stroma and epithelium.

Laser Fundus Imaging

Fundus imaging uses line scanning laser ophthalmoscopy, with a minimum pupil diameter of 3.0mm and a field of view of 40 by 30 degrees, so a surface view accompanies the layered study.

Wide Dioptre Compensation

The dioptre range runs from minus 20 to plus 20, covering a broad span of refractive error without separate correction at the instrument.

DICOM Conformance and Remote Viewing

DICOM conformance is listed, and remote viewer software is noted as available, so studies can be handled within the imaging arrangements a clinic already runs.

Glaucoma Detection and Monitoring

The glaucoma suite covers nerve fibre analysis, ganglion cell analysis, cup to disc analysis, progression analysis and comparative review of both eyes together. Two cube patterns, one over the macular area and one over the disc, sample evenly across 200 by 200 A-scans. For a clinic following patients with raised pressure or a suspicious disc, the value lies in repeatability: the same pattern captured at each review builds a record of whether the nerve fibre and ganglion cell picture is holding steady or drifting.

Macular Assessment and Progression

For the macula the software lists retinal thickness analysis, three dimensional viewing, en face review, progression analysis and the EDI function. Scan patterns include an HD line scan at 6 or 12 mm, a 3D scan at 6 mm by 6 mm, a 6-line radial scan and a multi pattern on a 5 by 5 grid. Point by point thickness across a 500 by 100 cube gives the numerical backing for a clinical impression formed at the slit lamp.

Corneal and Anterior Segment Work

Anterior imaging at high definition localises Bowman's layer, the interface between corneal stroma and epithelium. The anterior suite lists manual measurement together with corneal thickness and epithelial thickness analysis, drawn from an HD line scan at 6 or 16 mm or a 6-line radial scan. Practices doing contact lens work or assessing the corneal surface gain a layered view without changing instrument.

Shared Reporting and Teaching

DICOM conformance and remote viewer software mean a study need not stay on the machine that captured it. A clinician can review from another position, a colleague can be brought into a decision, and the layered image alongside the laser fundus view gives a clear basis for explaining findings to a patient or a student.

Posterior and Anterior on One Instrument

The scan pattern list runs from macular and disc cubes through to anterior segment line scans, and the analysis software carries matching suites for macula, glaucoma and anterior segment. A practice therefore covers retinal thickness work, glaucoma monitoring and corneal assessment without moving the patient between instruments or asking staff to learn separate workflows. For a clinic with one diagnostic room and a mixed appointment list, that breadth is the difference between a scan being routine and a scan being an event.

Measurement Built for Repetition

Evenly distributed sampling across 200 by 200 A-scans, a dense 500 by 100 thickness cube and progression analysis in both the macular and glaucoma suites are all aimed at the same thing, which is comparing today against last year with confidence. Comparative review of both eyes together adds a further reference point. Chronic eye disease is managed on trends, and the instrument is specified around producing them.

Fits Existing Imaging Arrangements

DICOM conformance and remote viewer software let captured studies move into the systems a clinic already uses rather than sitting in isolation. Laser fundus imaging supplies the surface view in the same session, so the record holds both the tomogram and the context around it. Where a practice reports remotely or shares cases with a hospital colleague, that flexibility saves duplicated imaging and keeps the patient pathway moving.

The Visionstar OSE-2800 is specified for a practice that wants one instrument to carry glaucoma monitoring, macular assessment and corneal work. The technical data sets out spectral domain methodology at an 840nm light centre wavelength, axial resolution of 5 microns optical, an A-scan depth of 3mm and a dioptre range from minus 20 to plus 20, with scan patterns defined separately for the macula, the disc and the anterior segment. Around that sit the analysis suites, laser fundus imaging at a 40 by 30 degree field, DICOM conformance and remote viewer software.

What the data does not state, this page does not claim. Housing dimensions, mass, electrical supply, software version, configuration and condition are absent from the material held, and nothing here should be read as a statement about testing or regulatory approval. Medigear.uk will confirm each of those points, together with the full model designation, before any decision is taken.
