Purpose Current perimeters use fixed grid patterns. We test whether a grid based on an individual's retinal nerve fiber layer (RNFL) thickness profile would find more visual field (VF) defects. Methods We describe the defect-based method for choosing test locations. First, the 26 VF locations with the highest positive predictive value to detect glaucoma from the 24-2 pattern are chosen. An ad...
PURPOSE To report retinal nerve fiber layer (RNFL) defect identification and quantification in RNFL thickness maps according to the structural RNFL loss, and to evaluate diffuse RNFL defects. METHODS A total of 170 patients with glaucoma and 186 normal subjects were consecutively enrolled. We defined RNFL defects in an RNFL thickness map by the degree of RNFL loss. The reference level for RNF...
BACKGROUND Although catheter ablation has been used to target the critical isthmuses for re-entrant monomorphic ventricular tachycardia in tetralogy of Fallot, the anatomy and histology of these regions have not been fully characterized. Autopsy hearts with tetralogy of Fallot were evaluated to clarify the pathological substrate. METHODS AND RESULTS Twenty-seven hearts with the diagnosis of t...
Friction stir lap welding of 7B04 aluminum alloy was conducted in the present paper, and the effect of welding speed on the defect features and mechanical performance of lap joints was investigated. The results indicate that the hook defect at the advancing side (AS) can reduce the effective thickness of the top sheet, and the sheet thinning level is gradually lowered by increasing the welding ...
The treatment of focal full thickness articular defects in the knee has continued to present a challenge, with no traditional treatment method providing consistent acceptable long-term clinical results. Patients with significant chondral defects frequently have persistent joint line pain, swelling, and catching in the knee. In contrast to marrow stimulation treatment techniques, such as abrasio...
RATIONALE It has been reported that epicardial adipose tissue (EAT) may affect myocardial autonomic function. OBJECTIVE The aim of this study was to explore the relationship between EAT and cardiac sympathetic nerve activity in patients with heart failure. METHODS AND RESULTS In 110 patients with systolic heart failure, we evaluated the correlation between echocardiographic EAT thickness an...
PURPOSE We compared the abilities of Stratus optical coherence tomography (OCT), Heidelberg retinal tomography (HRT) and standard automated perimetry (SAP) to detect the progression of normal tension glaucoma (NTG) in patients whose eyes displayed localized retinal nerve fiber layer (RNFL) defect enlargements. METHODS One hundred four NTG patients were selected who met the selection criteria:...
BACKGROUND Various techniques have been proposed for reconstruction of the eyelid anterior lamella after carcinoma excision: among these are the transposition of skin flaps, and full-thickness skin grafts or combination of these two. AIM To present our experience in eyelid reconstruction with full-thickness skin grafts and to assess the aesthetic and functional outcomes. PATIENTS AND METHOD...
The purpose of this study was to determine the sensitivity and positive predictive value of magnetic resonance imaging (MRI) in the identification of full-thickness articular cartilage defects in the porcine knee. Seventy-two full-thickness chondral defects (small or large; circular, oval, or triangular) were created in 12 porcine knees. The authors used 3.0-T MRI with 3-dimensional gradient ec...
Background: Risk of scar defect is inversely correlated with lower uterine segment thickness. The study aims to assess the diagnostic accuracy of sonographic measurement of the lower uterine segment thickness near term in predicting uterine scar defect in women with prior Caesarean section and ascertain the best cut-off value for predicting uterine rupture in our country. Methods: This observat...
