Ethnic differences in trabecular meshwork height by optical coherence tomography.
IMPORTANCE Differences in ocular anatomy may contribute to ethnic differences in glaucoma risk. Because the trabecular meshwork (TM) plays an important role in aqueous outflow, its anatomy in relation to at-risk populations may provide insight into a potential contributor to elevated intraocular pressure and thus to probability of glaucoma development. OBJECTIVE To investigate whether differe...
متن کاملVisibility of trabecular meshwork by standard and polarization-sensitive optical coherence tomography.
Polarization-sensitive optical coherence tomography (PS-OCT) is known to be advantageous because of its additional tissue-specific contrast of the anterior eye. So far, this advantage has been shown only qualitatively. We evaluate the improved visibility afforded by 3-D PS corneal and anterior eye segment OCT (PS-CAS-OCT) in visualizing the trabecular meshwork (TM) based on statistical evidence...
متن کاملTransverse Priority Phase Sensitive Optical Coherence Tomography
A variation on the standard time domain optical coherence tomography (TDOCT) system is presented. Using an inexpensive piezoelectric stack to modulate the reference mirror position, the amplitude and phase of the sample reflection is determined without scanning. With the primary scan in the transverse direction, en face and B-scan OCT images can be readily produced with phase information. This ...
متن کاملIntraoperative optical coherence tomography and ab interno trabecular meshwork surgery with the Trabectome
IMPORTANCE This study is the first description of the use of the intraoperative optical coherence tomography (iOCT) for trabecular meshwork surgery with the Trabectome in a regular clinical setting. BACKGROUND The aim of this study is to evaluate intraoperatively the immediate success of ab interno trabeculotomy with the Trabectome defined as a removal of the trabecular meshwork. DESIGN Thi...
متن کاملCollagen denaturation can be quantified in burned human skin using polarization-sensitive optical coherence tomography.
Quantifiable prognostic indicators are of considerable practical value following thermal injury. Collagen is a major component of the skin, and is known to undergo denaturation at the elevated temperatures associated with burns. The purpose of this study was to determine whether a recently developed, non-invasive imaging technique could detect and quantify collagen denaturation in burned human ...
