Quantitative analysis of neural tissues around the optic disc after panretinal photocoagulation in patients with diabetic retinopathy. [PDF]

open access: yesPLoS ONE, 2017
In this retrospective cross-sectional study, we quantitatively analyzed the tomographic features in the neural tissues around the optic disc in patients with diabetic retinopathy with and without panretinal photocoagulation.

Interpreting Retinal Nerve Fiber Layer Reflectance Defects Based on Presence of Retinal Nerve Fiber Bundles

open access: yesOptometry and Vision Science, 2021
SIGNIFICANCE Adaptive‐optics scanning‐laser‐ophthalmoscopy (AOSLO) retinal imaging of the retinal nerve fiber layer (RNFL) helps predict the severity of perimetric damage based on absence of fibers and projection of the defects in en face images of the RNFL from spectral‐domain optical coherence tomography (SD ...

Biomechanical, ultrastructural, and electrophysiological characterization of the non-human primate experimental glaucoma model. [PDF]

open access: yes, 2017
Laser-induced experimental glaucoma (ExGl) in non-human primates (NHPs) is a common animal model for ocular drug development. While many features of human hypertensive glaucoma are replicated in this model, structural and functional changes in the ...
