Identifying factors associated with fast visual field progression in patients with ocular hypertension based on unsupervised machine learning [PDF]

arXiv, 2023
Purpose: To identify ocular hypertension (OHT) subtypes with different trends of visual field (VF) progression based on unsupervised machine learning and to discover factors associated with fast VF progression. Participants: A total of 3133 eyes of 1568 ocular hypertension treatment study (OHTS) participants with at least five follow-up VF tests were ...

Forecasting Future Humphrey Visual Fields Using Deep Learning [PDF]

, 2018
Purpose: To determine if deep learning networks could be trained to forecast a future 24-2 Humphrey Visual Field (HVF). Participants: All patients who obtained a HVF 24-2 at the University of Washington. Methods: All datapoints from consecutive 24-2 HVFs from 1998 to 2018 were extracted from a University of Washington database.

Unraveling congenital ptosis with the aid of the pediatric perimeter device

Indian Journal of Ophthalmology, 2023
Background: Ocular morbidity with an early onset can have a significant impact on the long-term development of an individual. Hence, careful assessment of visual functions early on is very important.

Normative prospective data on automatically quantified retinal morphology correlated to retinal function in healthy ageing eyes by two microperimetry devices

Acta Ophthalmologica, EarlyView.
Abstract Purpose The relationship between retinal morphology, as assessed by optical coherence tomography (OCT), and retinal function in microperimetry (MP) has not been well studied, despite its increasing importance as an essential functional endpoint for clinical trials and emerging therapies in retinal diseases.

Tracking visual outcomes – Follow‐up on patients born preterm with childhood‐onset visual impairment

Acta Ophthalmologica, EarlyView.
Abstract Purpose Preterm birth is associated with a risk of ocular complications. The primary aim of the study was to evaluate the main cause of visual impairment (VI) in a cohort of preterm born patients who had childhood‐onset VI. The association between health‐related quality of life (HRQoL) and age, cause—and severity of VI and impairment type was ...
