Limbal cystotomy by fine needle aspiration of a translucent iris cyst in a horse

open access: yesEquine Veterinary Education, EarlyView.
Summary A 4‐year‐old Cremello crossbred mare was referred to the Equine Veterinary Teaching Hospital of Utrecht University for a translucent iris cyst from the dorsal pupillary margin corpora nigra in the right eye. Although noninvasive diode laser treatment is the preferred method of pigmented cyst ablation, two attempts did not result in disruption ...

Developmental stage ordering yields greater cranial mineralization sequence resolution than embryo size or days since oviposition: A case study using the gekkotan Eublepharis macularius (Blyth, 1854)

open access: yesJournal of Anatomy, EarlyView.
We employ a set of leopard gecko embryos for which size, day of development, and developmental stage are known to assess which timetable accords with the greatest resolution of cranial mineralization events. Developmental staging yielded the best outcome. Abstract Mineralization sequences of cranial elements (often referred to as ossification sequences)

Prevalence and outcome of lens capsule disruption in routine canine cataract surgery: A retrospective study of 520 eyes (2012–2019)

open access: yesVeterinary Ophthalmology, Volume 28, Issue 2, Page 141-149, March 2025.
Abstract Objective To investigate the prevalence and surgical outcome of lens capsule disruption (LCD) in dogs undergoing cataract removal. Animals studied Medical records of 924 eyes undergoing phacoemulsification were analyzed retrospectively. Procedures Routine cataract surgeries with or without LCD were included.

Dummy eye measurements of microsaccades: testing the influence of system noise and head movements on microsaccade detection in a popular video-based eye tracker [PDF]

open access: yes, 2015
Whereas early studies of microsaccades have predominantly relied on custom-built eye trackers and manual tagging of microsaccades, more recent work tends to use video-based eye tracking and automated algorithms for microsaccade detection. While data from

Traction suture fixation technique using a capsular tension ring fragment for severe lens displacement during cataract surgery in dogs

open access: yesVeterinary Ophthalmology, Volume 28, Issue 2, Page 197-206, March 2025.
Abstract Objectives To describe the traction suture fixation technique for severely displaced lenses (≥180°) using a capsular tension ring (CTR) fragment during cataract surgery in dogs, and to retrospectively investigate its clinical outcomes. Animals Studied Eight dogs (nine eyes). Procedures The medical records of dogs with severe lens displacement (

Optogenetics in primates: monkey see monkey look [PDF]

open access: yes, 2011
Optogenetics has emerged as a powerful tool for studying the neural basis of simple behaviors in rodents and small animals. In the primate model, however, optogenetics has had limited utility because optical methods have not been able to drive behavior ...
