    1. The role of optical coherence tomography angiography in moderate and advanced primary open-angle glaucoma

      The role of optical coherence tomography angiography in moderate and advanced primary open-angle glaucoma

      Purpose: To evaluate the relationship between structure and function in moderate and advanced primary open-angle glaucoma (POAG) and to determine the accuracy of structure and vasculature for discriminating moderate from advanced POAG. Methods: In this cross-sectional study, 25 eyes with moderate and 40 eyes with advanced POAG were enrolled. All eyes underwent measurement of the thickness of circumpapillary retinal nerve fiber layer (cpRNFL) and macular ganglion cell complex (GCC), and optical coherence tomography angiography (OCTA) of the optic nerve head (ONH) and macula. Visual field (VF) was evaluated by Swedish interactive threshold algorithm and 24-2 and 10-2 patterns. The correlation ...

    2. Evaluation of Anterior Segment Parameters in Pseudoexfoliation Disease Using Anterior Segment Optical Coherence Tomography

      Evaluation of Anterior Segment Parameters in Pseudoexfoliation Disease Using Anterior Segment Optical Coherence Tomography

      Purpose To compare anterior segment and angle parameters between pseudoexfoliation syndrome(PEX) and pseudoexfoliation glaucoma (PEXG) and normal control subjects by using anterior segment optical coherence tomography (AS-OCT) imaging. Design cross- sectional study Methods One hundred and two subjects with PEXG, PEX and normal eyes as the control group were recruited from academic referral institution. All subjects underwent complete ophthamologic examination, axial length measurement, AS-OCT imaging (CASIA SS-1000, Tomey). The anterior segment and angle parameters were evaluated. Results After excluding 4 eyes due to poor imaging of scleral spur, data from 34 eyes with pseudoexfoliation glaucoma (PEXG), 33 eyes with ...

    3. Changes in anterior segment optical coherence tomography following pars plana vitrectomy without tamponade

      Changes in anterior segment optical coherence tomography following pars plana vitrectomy without tamponade

      Background: To evaluate changes in anterior segment morphology on anterior segment optical coherence tomography (AS-OCT) following pars plana vitrectomy (PPV) without tamponade. Methods: Patients who underwent PPV without tamponade for epiretinal membrane were evaluated. Eligible patients underwent intraocular pressure (IOP) measurement and AS-OCT preoperatively as well as 1 month and 6 months post-operatively. Anterior chamber width (ACW), anterior chamber depth (ACD), trabecular iris angle (TIA), angle opening distance at 500 and 750 µm (AOD), and trabecular iris space area at 500 and 750 µm (TISA) at four quadrants were recorded and analyzed. Additionally, the mean values of TIA (MTIA), AOD ...

    4. Evaluation of Lamina Cribrosa and Choroid in Nonglaucomatous Patients With Pseudoexfoliation Syndrome Using Spectral-Domain Optical Coherence Tomography

      Evaluation of Lamina Cribrosa and Choroid in Nonglaucomatous Patients With Pseudoexfoliation Syndrome Using Spectral-Domain Optical Coherence Tomography

      Purpose : To evaluate the lamina cribrosa (LC) and peripapillary choroid in patients with pseudoexfoliation syndrome (PXS). Methods : In this cross-sectional study, one eye each of 32 nonglaucomatous PXS cases and 29 healthy volunteers were enrolled. The optic discs were scanned using enhanced depth imaging spectral-domain optical coherence tomography, and measurements were obtained using HEYEX software 6.0. LC and other related variables at three areas (mid-superior, center, and mid-inferior) and peripapillary choroidal thickness were determined. Linear mixed modeling was used to adjust the variables. Results : After adjustment for age, sex, and axial length, there was no significant difference between the ...

    5. Lens thickness assessment: anterior segment optical coherence tomography versus A-scan ultrasonography

      Lens thickness assessment: anterior segment optical coherence tomography versus A-scan ultrasonography

      AIM : To assess lens thickness measurements with anterior segment-optical coherence tomography (AS-OCT) in comparison with A-scan ultrasonography (A-scan US). METHODS : There were 218 adult subjects (218 eyes) aged 59.2±9.2y enrolled in this prospective cross-sectional study. Forty-three eyes had open angles and 175 eyes had narrow angles. Routine ophthalmic exam was performed and nuclear opacity was graded using the Lens Opacities Classification System III (LOCS III). Lens thickness was measured by AS-OCT (Visante OCT, Carl Zeiss Meditec, Dublin, CA, USA). The highest quality image was selected for each eye and lens thickness was calculated using ImageJ software. Lens ...

    6. COMPARISON OF ANTERIOR SEGMENT OPTICAL COHERENCE TOMOGRAPHY PARAMETERS BETWEEN CENTRAL RETINAL VEIN OCCLUSION AND NORMAL EYES: Is Primary Angle Closure a Risk Factor for Central Retinal Vein Occlusion?

      COMPARISON OF ANTERIOR SEGMENT OPTICAL COHERENCE TOMOGRAPHY PARAMETERS BETWEEN CENTRAL RETINAL VEIN OCCLUSION AND NORMAL EYES: Is Primary Angle Closure a Risk Factor for Central Retinal Vein Occlusion?

      Purpose: To compare anterior segment parameters in patients with central retinal vein occlusion (CRVO) with normal control subjects by anterior segment optical coherence tomography (AS-OCT). Methods: In this coss-sectional case-control study, 42 eyes from 21 patients with unilateral CRVO and 21 eyes from 21 age- and sex-matched healthy control subjects were recruited. Study eyes were divided into three groups: involved eyes of CRVO patients (CRVO eyes), fellow eyes of CRVO patients (fellow eyes), and control eyes. Complete ocular examination and AS-OCT were performed for each eye. The AS-OCT parameters (anterior chamber depth, scleral spur angle, angle opening distance [AOD] at ...

    7. Acute angle closure: qualitative and quantitative evaluation of the anterior segment using anterior segment Optical Coherence Tomography

      Acute angle closure: qualitative and quantitative evaluation of the anterior segment using anterior segment Optical Coherence Tomography

      Background To evaluate different mechanisms of acute angle closure(AAC), and to compare it with unaffected fellow eyes and primary angle closure suspects(PACS) using anterior segment optical coherence tomography(AS-OCT). Design Prospective, cross-sectional Methods In this clinic-based study,116 eyes(76 patients) with angle closure disease were included and categorized into three groups:1) AAC(40 eyes); 2) fellow eyes of AAC(40 eyes); and 3) PACS(36 eyes). Complete ophthalmic examinations including gonioscopy, A-scan biometry, and AS-OCT were performed. Main outcome measure Based on the AS-OCT images, 4 mechanisms of PAC including pupil block, plateau iris configuration, thick ...

      Ocular Biometry in the Subtypes of Angle Closure: An Anterior Segment Optical Coherence Tomography Study

      Purpose To evaluate ocular biometric parameters in different subtypes of angle-closure disease in the Iranian population and compare them with normal eyes. Design Prospective, cross-sectional. Methods In this clinic-based study, 189 eyes of 154 patients consisting of 40 acute angle-closure glaucoma (AACG) eyes, 40 fellow eyes of AACG, 42 chronic angle-closure glaucoma (CACG) eyes, 40 primary angle-closure suspect (PACS) eyes, and 27 normal eyes underwent complete examination including gonioscopy, A-scan biometry, and anterior segment optical coherence tomography. Only 1 eye of CACG, PACS, and control subjects were selected. Main outcome measures included angle opening distance and trabeculo-iris space area at ...
