Diurnal variation of optical coherence tomography–based macular fluid in exudative age-related macular degeneration

International Journal of Retina and Vitreous, 2023
Background Significant diurnal fluctuation of optical coherence tomography (OCT)-based macular fluid occurs in patients with several macular conditions including diabetic macular edema (DME) and cystoid macular edema due to retinal venous occlusion (RVO).

Area and volume ratios for prediction of visual outcome in idiopathic macular hole

International Journal of Ophthalmology, 2017
To predict the visual outcome in patients undergoing macular hole surgery by two novel three-dimensional morphological parameters on optical coherence tomography (OCT): area ratio factor (ARF) and volume ratio factor (VRF).A clinical case series was conducted, including 54 eyes of 54 patients with an idiopathic macular hole (IMH).

Hyperreflective Foci in the Inner Nuclear Layer: Proof‐of‐Concept for an Optical Coherence Tomography Derived Microglia‐Related Marker in Multiple Sclerosis

Annals of Neurology, EarlyView.
The role of microglia has emerged as a critical driver of disease progression in multiple sclerosis (MS), but we lack broadly applicable monitoring tools. Here, we investigated whether hyperreflective foci (HRF), as detected by optical coherence tomography (OCT) within the inner nuclear layer (INL) of the retina, can be used as a marker for microglial ...
