Forum Glaucoma Workplace is an exciting new medical software package that allows clinicians to manage their visual field and OCT data in one place. As well as allowing data to be viewed and manipulated, in a major step forward it also allows visual field/OCT combinatory analysis.
Additionally, as an option within the Forum Eyecare Management software, it opens up access to other benefits including viewing images from multiple devices on a single screen (ZEISS and non-ZEISS) and the ability to broadcast patient data to connected instruments, thus removing tiresome patient data entry.
Humphrey Field Analyser (HFA)
Glaucoma Workplace acts as remote review software for the Humphrey Field Analyser. For the first time, users are able to review and manipulate visual field analyses on a remote computer from one or more HFAs. This greatly improves workflow efficiency.
Using the same Statpac engine as the HFA itself, Glaucoma Workplace can generate multiple interactive reports, including Guided Progression Analysis (GPA) that enables users to reset baselines, include/exclude exams and play movie run-throughs of previous exams. The user can jump in and out of single tests directly from various reports, and view multiple visual field exams side-by-side.
Visual Field and OCT Combinatory Analyses
It is important to note that Forum works with the raw data from both the Humphrey Field Analyser and the Cirrus HD-OCT. This means that it can do more than just display static reports. In fact, Forum can effectively combine data from both instruments to produce reports that are not possible on either alone, giving the clinician important and never before possible structure and function insight.
The first of these is the Visual Field and Optic Disk Combined Report (see below). This report combines a 24-2 or 30-2 visual field test with the optic nerve head cube from the Cirrus HD-OCT. Glaucoma Workplace automatically matches the Retinal Nerve Fibre Layer (RNFL) data with the corresponding location on the visual field based on the work of Garway-Heath et al1, allowing clinicians to see whether defects on a visual field correspond with defects at the corresponding location in the RNFL anatomy.
A second report combines 10-2 visual field data from the HFA with the Ganglion Cell Analysis data from the Cirrus HD-OCT macular cube. As with the above report, Glaucoma Workplace automatically matches the visual field locations with those of the ganglion cell and inner plexiform layers based on the work of Hood et al.2
The Combined Reports are an important step forward in structure/function analysis and heralds an exciting new era where data from multiple instruments can be combined to make more meaningful information than isolated print-outs alone.
