The Investigation of Latanoprost's Effects on the Intraocular Pressure of Healthy Male guinea Pigs Under Light and Dark Regimes

Veterinary Medicine and Science, Volume 11, Issue 5, September 2025.
Latanoprost (0.005%) lowers intraocular pressure (IOP) more effectively in guinea pigs kept in darkness than in light. IOP reduction was significant at 7:00 and 8:00, with systemic absorption affecting untreated eyes. These results suggest that aligning treatment with circadian IOP variations may improve glaucoma management.

Temporal Protrusion of the Optic Disc Implicated in Central Visual Field Abnormalities in High Myopia: Two Case Reports

Case Reports in Ophthalmology
Introduction: Severe central visual field defects are frequently observed in highly myopic eyes. This report details 2 cases of central visual field defects in individuals with high myopia, characterized by an unusual temporal protrusion of the optic ...

Cerebrospinal Fluid Pressure and Glaucoma

Journal of Ophthalmic & Vision Research, 2013
Eyes with normal-pressure glaucoma and those with high-pressure glaucoma can show a similar optic nerve head appearance, while eyes with vascular optic neuropathies show a markedly different optic disc appearance.

Costello Syndrome and Ophthalmologic Issues: Unveiling the Unseen

American Journal of Medical Genetics Part A, Volume 197, Issue 7, July 2025.
ABSTRACT Costello syndrome (CS) is an ultra‐rare condition belonging to the RASopathies, a group of disorders characterized by aberrant RAS/MAPK pathway signaling, which is involved in ocular development and in some eye pathologies. However, only a few studies assessing the ophthalmic features of individuals with CS are available.

Lamina Cribrosa Depth in Different Stages of Glaucoma

Investigative Opthalmology & Visual Science, 2015
To compare lamina cribrosa (LC) depth between normal eyes and eyes with different stages of treated glaucoma.Serial enhanced depth imaging (EDI) optical coherence tomography (OCT) B-scans of the optic nerve head were obtained. To generate the mean LC depth for each eye, LC depths were measured in 11 equally spaced horizontal B-scans and averaged.

High resolution in vivo imaging of the lamina cribrosa

Saudi Journal of Ophthalmology, 2011
The lamina cribrosa (LC) is considered to be the principal site of retinal ganglion cell axon injury in glaucoma. Imaging technology has steadily improved in recent years, allowing greater resolution of fine details of laminar structure. Histological studies have elucidated the details of LC structure, both in normal and glaucomatous eyes, but such ...

Optic Disc Hemorrhage and Lamina Cribrosa Defects in Glaucoma Progression

Scientific Reports, 2017
Both disc hemorrhages (DH) and focal lamina cribrosa (LC) defects are recently considered as a progression factor in glaucoma. However, the clinical relevance of the presence of LC findings at the site of the DH has not yet been determined.
