Correlation of retinal nerve fiber layer thickness with perimetric staging in primary open-angle glaucoma – A cross-sectional study

Oman Journal of Ophthalmology, 2022
BACKGROUND: Glaucoma is a progressive optic neuropathy, characterized by structural optic nerve damage with corresponding field defects. Primary open-angle glaucoma (POAG) is the most common.

Selective and Inverse U-Shaped Curve Alteration of the Retinal Nerve in Amyotrophic Lateral Sclerosis: A Potential Mirror of the Disease

Frontiers in Aging Neuroscience, 2022
Introduction: Alterations in the visual pathway involving the retina have been reported in amyotrophic lateral sclerosis (ALS) but they lack consistency and subgroup analysis.

Tree shrew model of early diabetic retinopathy reveals microvascular dysfunction and identifies phosphoserine aminotransferase 1 as a novel therapeutic target

Animal Models and Experimental Medicine, EarlyView.
We developed an animal model of early diabetic retinopathy (DR) in the tree shrew by feeding a high‐fat and high‐sugar diet in combination with STZ. Physiological and biochemical index detection, hematoxylin and eosin staining, and transmission electron microscopy were performed to examine DR.

Correlating RNFL Thickness by OCT With Perimetric Sensitivity in Glaucoma Patients [PDF]

Journal of Glaucoma, 2011
To determine whether a structure-function model developed for normal age-related losses of retinal ganglion cells also models the retinal ganglion cell losses in glaucomatous optic neuropathy.The model to relate age-related loss of retinal nerve fiber layer thickness and reduced sensitivity for standard automated perimetry was evaluated with data from ...
