Detailed Information

Automated gonioscopy

Document. Assess. Plan.
A picture is worth a thousand words

 
Instant documentation with the GS-1

The GS-1 instantly documents the iridocorneal angle in real-color photographs and stores them in the device. Hence, there is no need for detailed drawing or sketches in the patient chart to record angle pathology. Photographs from the GS-1 can be attached to the patient file or chart. Documentation with the GS-1 is far simpler and much more definitive than subjective sketches of pathology.

 

Easy documentation and assessment with the GS-1.

The photographs can be checked on the touch screen of the device and easily magnified.

Documentation to be shared

Assessment of angle structure and pathology is easily facilitated by reviewing the digital photographs during clinical evaluation rather than performing manual gonioscopy. The digital photographs from the GS-1 can be shared from technicians to clinicians, with fellow clinicians, the referring physicians and patients, alongside complete documentation of GS-1 findings.

Focus on assessment and planning

 

Consultation with fellow clinicians

 

Effective information transfer to partner clinics

Easier patient consent
Assess and plan with documentation

The GS-1 frees up time for the clinicians to assess and plan treatment. The digital goniophotographs add the convenience of re-assessing the entire angle at any time. High resolution color photographs enhance the quality of assessment and allow comprehensive follow-up.

GS-1 features

Automated circumferential goniophotography

An internal optical system automatically rotates and acquires color photographs of the iridocorneal angle in 16 directions / 360 degrees documenting the entire angle. Each direction can be captured in 17 different foci, enabling a versatile approach to iridocorneal angle photography.

 

Export images

The images acquired by the GS-1 can be displayed as a single image, with circular stitching, or linear stitching. In addition to detailed assessment with single image, stitching allows localization of features/pathologies within the entire angle. High-resolution color images are exported in JPEG, PNG and PDF files.

Non-contact gel immersion measurement

To ensure patient comfort, a coupling gel is used during image acquisition. The multimirror prism is not intended to touch the cornea.

Traditional Goniophotography (e.g., manual photography of the angle) can be used for documenting and storing images of the angle structures. However, it is technically challenging and time-consuming and hence, is not routinely performed in clinical practice. Documentation of the angle is clinically important for keeping preoperative and postoperative records in cases of lens extraction for angle closure, trabecular surgery, and trauma. Furthermore, this documentation may be particularly relevant if medicolegal issues arise. In my view, as an instrument capable of automated 360 degrees Goniophotography, the GS-1 is a significant addition for enhancing clinical workflow.

“Gonioscopy findings could not only save your sight but your life.” The availability of standardized digital image capture of the anterior chamber angle acquired by a technician represents a new chapter in the history of ophthalmology. Easy storage, retrieval and analysis of angle images taken over time have now become a clinical reality. On a more personal note, thanks to the NIDEK automated Gonioscope, we discovered a melanocytoma in my right eye that would have otherwise remained undetected. The GS-1 is an excellent screening tool for primary and surgical cases of glaucoma.

Angle assessment is paramount in glaucoma management but remains a technically challenging procedure that is still performed manually by ophthalmologists. However, the recent introduction of the GS-1 automated gonioscopy device has allowed me to readily acquire high resolution 360º views of crucial angle structures, enhancing my ability to detect (and digitally store) clues for diagnosing pathology ranging from abnormal pigment to synechiae. The ability to magnify and analyze images allows greater familiarity with angle anatomy of each patient facilitating surgical planning. This utility is particularly important in an era of increasing use of surgical implants for glaucoma. Additionally, the digital images acquired with the GS-1 are especially beneficial during rounds and for educating my residents (and my patients). Lastly, access to digital images of the angle allows me conveniently assess and plan SLT treatments. I perform SLT with the YC-200 S plus laser which houses an optical system that allows me visualize angle structures with the same clarity as my slit-lamp. This user friendly laser has excellent maneuverability that allows delivery of laser procedures even in challenging cases.

Automated gonioscopy with the NIDEK GS-1 has helped optimize my clinical routine. Capturing high quality images of the entire circumference of the trabecular meshwork and the ability to review the images at will has enhanced clinical management and treatment follow-up. Most importantly, not taking manual notes on the gonioscopic exams allows me treat more patients and spend more time on care. The option to save images and generate reports allows me to thoroughly assess patient history (electronic documentation) and easily share the exam with other specialists for multidisciplinary consult. These advantages would not be possible without this device. For MIGS surgeons, the GS-1 is an excellent tool for surgical planning, patient education and post-implant evaluation. In summary, this one-of-a-kind device meets multiple clinical demands with the benefits of automated acquisition and documentation of gonioscopic images.

The NIDEK GS-1 is a powerful device for collecting accurate true-colour pictures of the entire anterior chamber angle. I currently use GS-1 primarily for three clinical applications: – Document a closed-angle before performing an angle-opening procedure – Document challenging cases necessitating close follow-up – Record a view of the angle collected by a technician for asynchronous evaluations Furthermore, having a dataset of good quality angle pictures comprising a broad spectrum of conditions is a potent tool for teaching gonioscopy to ophthalmologists-in-training, including increasing their familiarity of rare phenotypes. With the GS-1, NIDEK has transformed the time-consuming and neglected task of manual gonio-photography into a friendly, easy and automated process. In my opinion the NIDEK GS-1 is not aimed to replace standard slit-lamp gonioscopy. Hence, the GS-1 should be considered a technique for improving anterior chamber angle assessments akin to wide-field retinography for ophthalmoscopy.
