Tonographic Effect of Ocular Response Analyzer in Comparison to Goldmann Applanation Tonometry

PLOS ONE, 2017
The tonographic effect is a phenomenon of intraocular pressure (IOP) reduction following repeated tonometry. This study examines whether the tonographic effect occurs following IOP measurement performed with Ocular Response Analyzer (ORA).Both eyes of 31 glaucoma patients and 35 healthy controls underwent nine IOP-measurements performed with GAT and ...

Ultrafast fMRI Detects Age‐Related Changes in Harmonics of Cardiac Pulsations in the Brain at 7 T

Magnetic Resonance in Medicine, Volume 96, Issue 3, Page 1206-1218, September 2026.
ABSTRACT Purpose Aging impacts pulsatility of blood vessels in the brain, reflecting vascular health. Resolving characteristics of cardiac pulsatility requires faster acquisitions than traditional fMRI. An ultrafast fMRI method was developed and applied to sample several harmonics of cardiac pulsations at 7 T.

Agreement between ganglion cell‐inner plexiform layer metrics from widefield optical coherence tomography and Goldmann II, III, and V in glaucoma

Optometry and Vision Science, Volume 103, Issue 7, July 2026.
ABSTRACT Purpose To compare concordance between ganglion cell‐inner plexiform layer metrics acquired using widefield optical coherence tomography (OCT) and visual function assessed using Goldmann (G) II, III, and V stimulus sizes, in turn evaluating the role of spatial summation properties in binary classification of visual field (VF) results.

Reference Intervals for Schirmer Tear Test and Intraocular Pressure in Healthy Hamdani Crossbred Sheep

Veterinary Medicine and Science, Volume 12, Issue 4, July 2026.
This study establishes reference intervals for Schirmer tear test (STT) and intraocular pressure (IOP) in healthy Hamdani crossbred sheep. STT values were lower and IOP values higher than previously reported, highlighting the importance of breed‐specific reference ranges in clinical ophthalmic evaluation.

Hyaluronic Acid‐Based Photocurable Glue Application as an Alternative Surgical Approach for Corneal Injuries in Canine Patients: A Case Series

Veterinary Medicine and Science, Volume 12, Issue 4, July 2026.
• Hyaluronic acid (HA)–based photocurable glue was applied to deep corneal injuries in dogs as a minimally invasive alternative when surgery was not feasible. • The adhesive was delivered to the lesion and rapidly photocrosslinked using 405 nm visible light, creating a stable protective barrier.
