Jun 29, 2024 · Usually, three primary methods of visual field testing are performed clinically: (1) static perimetry, (2) kinetic perimetry, and (3) suprathreshold static perimetry. These procedures have specific advantages and disadvantages, and each can be useful for clinical evaluation.
4 days ago · 2.3 Assessment of visual field defect size and severity. Relative size and severity of CB visual impairments were estimated using a Humphrey Visual Field Analyzer II-i at two study sites (87 patients), and a Humphrey Visual Field Analyzer 3 at a third site (eight patients), with all sites using a 24-2 testing protocol.
2 days ago · The results showed that the use of the eye tracker showed that patients with brain damage and an altered visual field require more time to complete a reading-text test by fixating a greater number of times (p < 0.001); with longer fixations (p = 0.03); and a greater number of saccades in these patients (p = 0.04).
4 days ago · Virtual visual field (VVF) testing, utilizes portable devices to assess a patient's visual field. Unlike traditional tabletop perimeters, which are stationary and require a dedicated space in the clinic, virtual perimeters are compact and can be used in various settings. These user-friendly devices use a headset to project visual stimuli and ...
2 days ago · Understanding the Visual Field. The visual field is the entire area that can be seen when the eye is focused on a central point, and it includes both central and peripheral vision. In glaucoma, damage to the optic nerve can result in specific patterns of visual field loss, such as blind spots or reduced sensitivity to light in certain areas.
2 days ago · Glaucoma is a leading cause of visual field loss and can result in permanent vision impairment if left untreated. Surgical options such as trabeculectomy and minimally invasive glaucoma surgery (MIGS) can help enhance visual field in glaucoma patients. Patients need to be aware of the pre-surgery preparations, including medication adjustments ...
2 days ago · Visual field (VF) testing is a critical tool for evaluating vision loss and identifying and monitoring diseases such as glaucoma. For all its diagnostic virtue, it has long been a pain point for eye care professionals, their practices, and most especially their patients. Standard automated perimetry (SAP) consumes considerable time and physical ...
