Circadian Macular Volume Changes in the Healthy Human Choroid

American Journal of Ophthalmology, 2015
To investigate a potential circadian fluctuation of the choroidal volume in healthy adults by enhanced depth imaging (EDI) via spectral-domain optical coherence tomography (SD OCT).Prospective observational case series.Thirty healthy eyes of 15 healthy subjects with a median age of 26 years (range 22-55) underwent EDI SD OCT scans for macular choroidal

Thickness of the Retinal Nerve Fiber Layer, Macular Thickness, and Macular Volume in Patients With Strabismic Amblyopia

Journal of Pediatric Ophthalmology & Strabismus, 2005
Objective: To compare the thickness of the retinal nerve fiber layer (RNFL), the macular volume, and the macular thickness of the amblyopic eye with those of the non-amblyopic eye in patients with unilateral strabismic amblyopia using optical coherence tomography (OCT). Patients and Methods:

MACULAR CHOROIDAL VOLUME CHANGES AFTER INTRAVITREAL BEVACIZUMAB FOR EXUDATIVE AGE-RELATED MACULAR DEGENERATION

Retina, 2017
Purpose: To evaluate the effect of intravitreal bevacizumab on the macular choroidal volume and the subfoveal choroidal thickness in treatment naïve eyes with exudative age-related macular degeneration. Methods: The macular choroidal volume and the subfoveal choroidal thickness were

Construction of a Retinal Atlas for Macular OCT Volumes

2018
Optical Coherence Tomography (OCT) plays an important role in the analysis of retinal diseases such as Age-Related Macular Degeneration (AMD). In this paper, we present a method to construct a normative atlas for macula centric OCT volumes with a mean intensity template (MT) and probabilistic maps for the seven intra-retinal tissue layers.

Associations between chronic glycosylated haemoglobin (HbA1c) level and macular volume in diabetes patients without macular oedema

Acta Ophthalmologica, 2009
Acta Ophthalmol. 2010: 88: 753–758Abstract.Purpose:  This study aimed to examine the correlation between glycosylated haemoglobin (HbA1c) level and macular volume in diabetes patients without diabetic macular oedema (DMO).Methods:  We carried out an observational, cross‐sectional study.

Higher macular volume in patients with MS receiving fingolimod

Neurology, 2013
In the evaluation of patients with multiple sclerosis (MS), optical coherence tomography (OCT) is gaining traction as a tool to assess thinning of the retinal nerve fiber layer (RNFL) and, more recently, for looking at total macular volume (TMV) thickness, with both measures used as potential biomarkers for progression of disease.

Reproducibility of qualitative assessment of drusen volume in eyes with age related macular degeneration

Eye, 2020
Although an optical coherence tomography (OCT)-derived central drusen volume ≥0.03 mm3 has been found to be a risk factor for progression to late age-related macular degeneration (AMD), this parameter is not currently available on most OCT devices or acquisition protocols.

The Effects of the Frequency of the Initial Treatment with Intravitreal Bevacizumab on Macular Volume and Visual Acuity

Journal of Ocular Pharmacology and Therapeutics, 2015
The ideal notion of monthly intravitreal injections is difficult to achieve when it comes to real-life scenarios. In reality, patients often are treated with larger intervals due to circumstances. The purpose of this study was to compare the results of intravitreal bevacizumab injections with shorter intervals versus longer intervals for the treatment ...

Analysis of macular volume in normal and glaucomatous eyes using optical coherence tomography

American Journal of Ophthalmology, 2003
To evaluate macular volume in normal and glaucomatous eyes using optical coherence tomography (OCT).Case control study.The authors assessed 272 eyes of 164 subjects as part of an institutional study at New England Eye Center in Boston, Massachusetts; 202 eyes were in the study group and 70 eyes in the control group.
