Short Wavelength Automated Perimetry and Peripapillary Retinal Nerve Fiber Layer in Early Diabetes

Philippine Journal of Ophthalmology, 2016
Objective: To investigate the significance of short wavelength automated perimetry (SWAP) in detecting retinal functional impairment in early diabetic patients without retinopathy and with mild non-proliferative diabetic retinopathy (NPDR).

Apple Vision Pro’s new technology as a head-mounted perimetry device for glaucoma and other potential applications

The Pan-American Journal of Ophthalmology
Glaucoma is a leading cause of irreversible blindness worldwide and poses a significant public health challenge. Primary open-angle glaucoma (POAG) is the most common form of glaucoma and is marked by progressive optic nerve damage and peripheral visual ...

Image quality characterization of near‐eye displays

Journal of the Society for Information Display, Volume 33, Issue 3, Page 101-121, March 2025.
We review the literature and relevant standards related to image quality characterization of medical devices using near‐eye displays (NEDs). First, we discuss the experimental considerations, alignment methods. Second, we review image quality characterization for luminance, contrast, spatial resolution, geometrical distortion, and spatiotemporal ...

Using Fused Data from Perimetry and Optical Coherence Tomography to Improve the Detection of Visual Field Progression in Glaucoma

Bioengineering
Perimetry and optical coherence tomography (OCT) are both used to monitor glaucoma progression. However, combining these modalities can be a challenge due to differences in data types. To overcome this, we have developed an autoencoder data fusion (AEDF)

Harnessing the power of artificial intelligence for glaucoma diagnosis and treatment

Kerala Journal of Ophthalmology
Artificial intelligence (AI) has great potential for diagnosing and managing glaucoma, a disease that causes irreversible vision loss. Early detection is paramount to prevent visual field loss.

RLPeri: Accelerating Visual Perimetry Test with Reinforcement Learning and Convolutional Feature Extraction [PDF]

The 38th Annual AAAI Conference on Artificial Intelligence, 2024
Visual perimetry is an important eye examination that helps detect vision problems caused by ocular or neurological conditions. During the test, a patient's gaze is fixed at a specific location while light stimuli of varying intensities are presented in central and peripheral vision.

Chromatic-achromatic perimetry in four clinic cases: Glaucoma and diabetes

Indian Journal of Ophthalmology, 2015
Background: Some diseases that affect the visual system may show loss of chromatic-achromatic sensitivity before obvious physical signs appear in the usual examination of the eye′s posterior segment.

Using artificial intelligence methods for the studyed visual analyzer [PDF]

arXiv
The paper describes how various techniques for applying artificial intelligence to the study of human eyes are utilized. The first dataset was collected using computerized perimetry to investigate the visualization of the human visual field and the diagnosis of glaucoma. A method to analyze the image using software tools is proposed. The second dataset
