NIDEK GS-1 Digital Gonioscope
Digital gonioscope
The NIDEK GS-1 Digital Gonioscope provides automated, high-resolution imaging of the anterior chamber angle. It allows clinicians to evaluate the drainage angle precisely and efficiently with full 360° digital coverage. Equipped with an automated rotating optical system, the GS-1 captures a complete view of the anterior chamber without the need to manually reposition the lens. This innovation reduces variability and enhances image consistency, helping ophthalmologists achieve accurate, repeatable diagnostic results. Compatible with slit lamp systems and image management software, the GS-1 is an essential tool for modern ophthalmic practices.

NIDEK
The NIDEK GS-1 combines advanced optical design with digital imaging to provide a full 360° view of the anterior chamber angle. A single automated scan captures the entire structure using multiple mirrors, minimizing patient discomfort and examination time. Its high-resolution CCD sensor delivers true-color images that can be saved, analyzed, and compared, supporting accurate diagnosis and efficient treatment planning. The GS-1 transforms gonioscopy into a fast, standardized, and user-friendly procedure for clinicians and patients alike.
Detailed information
NIDEK GS-1 Digital Gonioscope – an Innovative Solution for Ophthalmic Diagnostics
The NIDEK GS-1 Digital Gonioscope is an advanced ophthalmic device that automates the documentation and assessment of the iridocorneal angle through high-resolution color photography. The system instantly captures a complete image of the anterior chamber angle, eliminating the need for manual sketches or drawings in patient records. Images are stored within the device and can be easily attached to patient files or medical databases, providing standardized and definitive documentation. A touch-screen display allows quick review and magnification of images, simplifying clinical assessment and comparison. The digital goniophotographs can be seamlessly shared among technicians, clinicians, referring physicians, and partner clinics, facilitating collaboration, education, and informed patient consent.
The GS-1 streamlines clinical workflow by freeing physicians to focus on diagnosis and treatment planning. High-resolution color photographs enable comprehensive evaluation and follow-up of angle anatomy and pathology, including postoperative cases such as MIGS, laser iridotomy, trabeculectomy, and others. The device’s automated internal optical system rotates and captures images in 16 directions over a full 360°, with up to 17 focal planes per direction, providing a complete, multi-layered representation of the angle without manual operation. Images can be exported in JPEG, PNG, or PDF formats, displayed as single, circular, or linear stitched views to localize anatomical or pathological features across the entire angle.
For maximum patient comfort, a non-contact gel immersion system ensures the prism does not touch the cornea.
When integrated with the optional NAVIS-EX software, GS-1 data can be stored, compared, and reviewed over multiple visits, allowing progressive evaluation of treatment outcomes. The “focus stacking” technology merges up to 15 images from different focal depths into one all-in-focus composite image. Image acquisition can be performed by auxiliary staff, enabling efficient workflow while the physician concentrates on clinical analysis.
The NIDEK GS-1 sets a new standard for digital gonioscopy — combining automation, precision, and clinical efficiency in modern ophthalmic practice.
