A 62-year-old woman was admitted with chest pain of two hours' duration, ECG changes in the precordial leads and left ventricular ejection fraction of 30% on the echocardiogram. Emergent catheterization demonstrated severe flow disturbance in the left coronary artery. An intra-aortic balloon pump and a drug-eluting stent were implanted. However, the flow disturbance persisted. Optical coherence tomography followed by intravascular ultrasound provided crucial data on the mechanism and helped to optimize treatment in this critical patient...

PURPOSE: To evaluate the effects of panretinal photocoagulation on spectral domain optical coherence tomography measurements in diabetic retinopathy by comparing the thicknesses of the central macula, retinal nerve fiber layer, and ganglion cell layer, we used a Cirrus HD OCT® (Carl Zeiss Meditec, Dublin, CA, USA) in normal and diabetic retinopathy cohorts. METHODS: We analyzed patients who visited our retinal clinic between May 2013 and July 2014. The patients were classified into four groups: normal (Group A), diabetes without diabetic retinopathy (Group B), severe nonproliferative or proliferative diabetic retinopathy (Group C), and at least 3 years after panretinal photocoagulation treatment (Group D)...

INTRODUCTION: Radiographic methods have poor sensitivity for occlusal lesions and by the time the lesions are radiolucent they have typically progressed deep into the dentin. New more sensitive imaging methods are needed to detect occlusal lesions. In this study, cross-polarization optical coherence tomography (CP-OCT) and near-IR imaging were used to image questionable occlusal lesions (QOC's) that were not visible on radiographs but had been scheduled for restoration on 30 test subjects...

The aim of the present study was to evaluate mutations of the G protein-coupled receptor 143 (GPR143) gene for ocular albinism type 1 (OA1) in Chinese patients. For the current study, 8 patients with OA1 were selected from the database of ocular genetic diseases. Genomic DNA of OA1 was prepared from venous leukocytes collected from the patients. Cycle sequencing was used to analyze the exons and adjacent introns of GPR143. The variation detected was analyzed by bidirectional DNA sequencing and further evaluated in 96 controls using heteroduplex‑single strand conformational polymorphism analysis...

PURPOSE: To evaluate the impact of preoperative central foveal thickness (CFT) on visual acuity after surgery in patients with idiopathic vitreomacular traction and to calculate a cut-off value in preoperative CFT. METHODS: Thirty-five patients with idiopathic vitreomacular traction were evaluated retrospectively. A complete ophthalmological examination including spectral domain optical coherence tomography was performed preoperatively and at 12 months after the surgery...

PURPOSE: To examine the efficacy and safety of Ruthenium-106 plaque radiotherapy in the treatment of circumscribed choroidal hemangioma. METHODS: Twenty-one eyes of 21 patients diagnosed with symptomatic circumscribed choroidal hemangioma who underwent Ruthenium-106 plaque radiotherapy were included in the study. Clinical response, ancillary tests finding improvement, and major side effects were evaluated. RESULTS: From the initial to the 1-year follow-up visits, vision improved in 12 eyes (57%), was stable in 7 eyes (33%), and became worse in 2 eyes (10%)...

AIM: The aim of the study was to investigate the interchangeability and reliability of macular perfusion measurements using optical coherence tomography angiography. METHODS: A prospective cross-sectional observational study. Healthy adult Chinese subjects were recruited. Macular perfusion parameters were automatically analysed by software included in a spectral-domain optical coherence tomography system. The vessel density (VD) of the whole, parafovea, superior-hemi, inferior-hemi, fovea, temporal, superior, nasal and inferior quadrants as well as the foveal avascular zone (FAZ) and choroidal capillary VD (CCVD) were quantified...

OBJECTIVE: To study the influence of optic disc edema (ODE) on the dimensions of the disc and the thickness of the retinal nerve fiber layer (RNFL) by optical coherence tomography (OCT) in Lomé. PATIENTS AND METHODS: This was a retrospective study which took place in a general ophthalmology office in the city. Twenty-six eyes were examined for ODE (cases) between January 2013 and May 2015, and 26 healthy eyes (control group) were considered in this study. The control group was recruited taking age into account with a variation not exceeding 5 years compared to the ODE cases...

Retinal detachment is an acute disorder in humans that is caused by trauma or disease, and it can often lead to permanent visual deficits that result from the death of photoreceptors in the retina. The final pathway for photoreceptor cell death is apoptosis and necroptosis. The X-linked inhibitor of apoptosis (XIAP) has been shown to block both of these cell death pathways. We tested the effects of XIAP on photoreceptor survival in a feline model of retinal detachment. The study was performed in 12 cats, divided into 2 experimental groups...

PURPOSE: To evaluate the sectoral and global structure-structure (vessel density-retinal nerve fiber layer thickness) and structure-function (vessel density-visual sensitivity loss) relationships of peripapillary vessel density measurements on optical coherence tomography angiography in primary open-angle glaucoma and to determine if fractional polynomial (FP) models characterize the relationships better than linear models. MATERIALS AND METHODS: In a cross-sectional study, structure-structure and structure-function relationships of peripapillary vessel densities were determined in 227 eyes of 143 subjects (63 control and 164 primary open-angle glaucoma eyes) who had undergone standard automated perimetry and optical coherence tomography testing within 6 months of each other, using linear and FP models...
