Lessons Learned: Quality Analysis of Optical Coherence Tomography in Neuromyelitis Optica

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Introduction Optical coherence tomography (OCT)‐derived retina measurements are markers for neuroaxonal visual pathway status. High‐quality OCT scans are essential for reliable measurements, but their acquisition is particularly challenging in eyes with severe visual impairment, as often observed in neuromyelitis optica spectrum disorders ...

Pharmacogenetics and Age-Related Macular Degeneration

Journal of Ophthalmology, 2011
Pharmacogenetics seeks to explain interpatient variability in response to medications by investigating genotype-phenotype correlations. There is a small but growing body of data regarding the pharmacogenetics of both nonexudative and exudative age ...

Age-related Macular Degeneration

International Ophthalmology Clinics, 1986
Age-related macular degeneration (AMD) is a major cause of visual loss. The atrophic form is more frequent but accounts for only 20% of severe visual loss. The neovascular form accounts for 80% of severe visual loss. The Macular Photocoagulation Study demonstrated that prompt argon laser photocoagulation can significantly reduce the risk of severe ...

Cell Calcification Models and Their Implications for Medicine and Biomaterial Research

Advanced Healthcare Materials, EarlyView.
Calcification, is the process by which the tissues containing minerals are formed, occurring during normal physiological processes, or in pathological conditions. Here, it is aimed to give a comprehensive overview of the range of cell models available, and the approaches taken by these models, highlighting when and how methodological divergences arise,
