    2. Vitreous Hyper-Reflective Dots in Optical Coherence Tomography and Cystoid Macular Edema after Uneventful Phacoemulsification Surgery

      Vitreous Hyper-Reflective Dots in Optical Coherence Tomography and Cystoid Macular Edema after Uneventful Phacoemulsification Surgery

      Purpose To report the observation of hyper-reflective dots in the vitreous cavity using spectral domain optical coherence tomography (SD-OCT) after uneventful phacoemulsification cataract surgery and to investigate their association with cystoid macular edema (CME). Materials and Methods Medical records of consecutive Asian patients who had no preoperative retinopathy and underwent uneventful phacoemulsification cataract surgery from March 2012 through February 2013 were reviewed. SD-OCTs were performed before, 1 week, and 1 month after surgery. The number of vitreous hyper-reflective dots (VHDs) was counted in 5 OCT images of high-definition 5-line raster scans. The development of CME was assessed using postoperative 1-month ...

    4. Macula and Retinal Nerve Fiber Layer in Migraine Patients: Analysis By Spectral Domain Optic Coherence Tomography

      Macula and Retinal Nerve Fiber Layer in Migraine Patients: Analysis By Spectral Domain Optic Coherence Tomography

      Aim : Investigating the retinal nerve fiber layer (RNFL), macular and ganglion cell complex thickness in eyes of migraine patients using optical coherence tomography. Methods : The study was designed as an observational cross-sectional study. 50 patients with migraine (30 patients with aura and 20 patients without aura) and 50 healthy volunteers were included. Optical coherence tomography was performed with Optovue technology. The fast RNFL thickness (3.4) scan, MM5, and GCC acquisition protocols were used. Results : There was no statistically significant difference in retinal thickness in any of the quadrants between the control group and the migraine patients ( p  > 0.05 ...

    5. Evaluation of the Anterior Chamber Angle in Glaucoma: A Report by the American Academy of Ophthalmology

      Evaluation of the Anterior Chamber Angle in Glaucoma: A Report by the American Academy of Ophthalmology

      Objective To assess the published literature pertaining to the association between anterior segment imaging and gonioscopy and to determine whether such imaging aids in the diagnosis of primary angle closure (PAC). Methods Literature searches of the PubMed and Cochrane Library databases were last conducted on July 6, 2011. The searches yielded 371 unique citations. Members of the Ophthalmic Technology Assessment Committee Glaucoma Panel reviewed the titles and abstracts of these articles and selected 134 of possible clinical significance for further review. The panel reviewed the full text of these articles and identified 79 studies meeting the inclusion criteria, for which ...

    7. Simultaneous 3D imaging of sound-induced motions of the tympanic membrane and middle ear ossicles

      Simultaneous 3D imaging of sound-induced motions of the tympanic membrane and middle ear ossicles

      Efficient transfer of sound by the middle ear ossicles is essential for hearing. Various pathologies can impede the transmission of sound and thereby cause conductive hearing loss. Differential diagnosis of ossicular disorders can be challenging since the ossicles are normally hidden behind the tympanic membrane (TM). Here we describe the use of a technique termed optical coherence tomography (OCT) vibrography to view the sound-induced motion of the TM and ossicles simultaneously. With this method, we were able to capture three-dimensional motion of the intact TM and ossicles of the chinchilla ear with nanometer-scale sensitivity at sound frequencies from 0.5 ...

    9. Quantitative Distinction of Unique Vocal Fold Subepithelial Architectures Using Optical Coherence Tomography

      Quantitative Distinction of Unique Vocal Fold Subepithelial Architectures Using Optical Coherence Tomography

      Objectives : The primary objective of this study was to quantitatively analyze ex vivo porcine, fetal human, and adult human vocal folds by use of optical coherence tomography (OCT). A secondary objective was to quantitatively discriminate among 1-, 2-, and 3-layer lamina propria structures. Methods : We performed an analysis of the vocal folds of 10 adult pig, 3 adult human, and 2 fetal human vocal fold specimens using OCT and histologic techniques. We present a quantitative comparison of the OCT results and histologic findings. Results : We found that OCT allowed for the visualization of the subepithelial vocal fold architecture of all ...

    10. Macular Imaging for Glaucoma Using Spectral-domain Optical Coherence Tomography: A Review

      Macular Imaging for Glaucoma Using Spectral-domain Optical Coherence Tomography: A Review

      Since its introduction, optical coherence tomography (OCT) has become widely used and accepted as an imaging modality to detect and follow glaucoma, with measurement of the peripapillary retinal nerve fiber layer (pRNFL) being the most utilized parameter. Up until recently, macular thickness parameters have not been commonly used in glaucoma due to results of earlier studies with time-domain OCT (TD-OCT) that revealed macular imaging to be inferior to pRNFL in the diagnosis of glaucoma. The recent advent of spectral-domain OCT (SD-OCT) has renewed interest in the potential uses of macular imaging in glaucoma due to its ability to better segment ...

    11. The Use of Fourth-generation Optical Coherence Tomography in Multiple Sclerosis: A Review

      The Use of Fourth-generation Optical Coherence Tomography in Multiple Sclerosis: A Review

      Optical coherence tomography (OCT) has been routinely used to obtain high spatial resolution images of the retina and choroid non-invasively. Within the past decade, a fourth-generation OCT device using Fourier domain (FD) analysis has been developed that provides higher velocity and higher axial resolution images with better reproducibility than the previous generation time domain (TD) OCT technology. This review addresses the use of fourth-generation, FD ocular OCT in patients with multiple sclerosis.

    12. Enhanced Depth Imaging Optical Coherence Tomography in Age-related Macular Degeneration

      Enhanced Depth Imaging Optical Coherence Tomography in Age-related Macular Degeneration

      Imaging of the choroidal layer has been limited with the conventional commercial SD-OCTs. Enhanced depth imaging optical coherence tomography (EDI-OCT) is a modification of the standard spectral-domain OCT (SD-OCT) technique that enables better non-invasive imaging of the choroid. This review contains an introduction of EDI imaging technique and principles and summarizes the findings of EDI-OCT imaging in age-related macular degeneration.
