The Centervue DRS is like that gifted toy on Christmas that makes you realize you’re living in your parent’s future. It was the first fundus imaging system that truly was automated– requiring only the ‘Start’ button to self-align and capture the perfectly aligned retinal photo. Its movements remind you of the perfectly tuned sports car– and its intuition puts you in the realization that robotics are among us. It is undoubtedly a staff favorite around these parts despite not being at the forefront of resolution or filed of view; we like to look at its ‘boat-like’ silhouette as well. Some users are quick to mention that the DRS’ alignment takes longer (in aggregate) than a semi-manual device– and since there is no initial manual override, patient compliance is a must. These things all may be true- but the automation eliminates the operator need to be fully in-tune to the procedure– start working on something else in the pretest room (would-ya?). And if you’re dealing with a patient population that can’t hold still,- the DRS isn’t right for you anyways. We also thoroughly enjoy the DRS’ self-contained interface and storage– making the camera feel like a modern smart phone with everything you need right in front of you. Unlike external fundus softwares, patient data is available immediately, allowing the operator to easily enter information, or review past visits with current visit-photos. The 10-inch LCD touch screen was clearly well thought-out, reacting to your immediate request without fuss and is most definitely a major attribute of the DRS.
OUR TAKE: Robotics is sexy– and it’s not just ‘show business’ either. The user interface is very well thought out- and communicates well with the unit’s fully automated optical head. Sometimes too much automation can take more time; patient compliance required.
Extreme ease of use: patient auto-sensing, auto-alignment, and auto-focus all come standard.
Simply select the on-screen “Start” button, and the instrument automatically adjusts the flash-intensity with regard to the capture time.
With a large built-in hard drive, and easy-to-use user interface, the DRS eliminates the need for external computer or software– allowing instant review and transfer of every image. The DRS’ software also allows tracking of patient progression over time.
The DRS’ 5 megapixel CCD camera sensor producing 48 pixels/deg creates quality photos comparable to that of other modern fundus imaging systems. Edit, magnify, and manipulate photos directly on the system itself– no need for external viewing or storage.
A 10.4″ color LCD-touch-screen is beautifully oversized, to give the operator the perfect slate to review, edit, and save photos all on the instrument itself.
The DRS’ internal camera sensor works together to adjust the flash exposure to only what’s necessary to produce a quality photograph. Unlike other instruments which force you to adjust the illumination, the DRS does it all for you– preventing over exposed photos, and patient discomfort.
The DRS does take a bit longer than other fundus cameras- capturing both eyes sufficiently within 60 seconds (excluding data entry). Some patients take a bit longer, others are much quicker. Capture alignment does depend on corneal environment, as well as patient compliance.
The DRS is networkable and offers both proprietary and custom networking options. Wi-Fi and Ethernet capable- or export to USB and remote folder (for import into EMR), DICOM, JPG, PDF.
There is a manual override, only after the DRS fails initially to capture an adequate image. On-screen controls allow you to adjust the optical head for proper alignment of the eye. The DRS does not however feature live viewing via real-time camera feed. Rather, it displays a real-time graph showing the alignment of the eye.
