Objective To seak a available way of evaluating morphology of filtering blebs after trabeculectomy is very important for forecasting the successful rate of surgery.At the present time,filtering blebs were commonly evaluated by using the slim lamp microscope,but it did not to exactly reflect the filtering passage.This study aimed to evaluate the morphology of filtering blebs after trabeculectomy with anterior segment optical coherence tomography (AS-OCT).MethodsThis was a prospective study.Sixty-nine eyes of 53 patients who had previously undergone trabeculectomy were selected in this study,including 25 eyes with open-angle glaucoma,38 eyes with close-angle glaucoma and 6 eyes with secondary glaucoma.These filtering blebs were classified into functional type (typeⅠandⅡ) and nonfunction type (type Ⅲ and Ⅳ) under the slit lamp microscope based on the van Buskirk grading scales.Intra-bleb morphology and structure were characterized as diffuse-like,cystic-like,encapsulating-like and flatten-like by AS-OCT in reference to the Leung method.The consistency between the two methods was evaluated by the Chi-Square test.Written informed consent was obtained from all the patients before surgery.ResultsThe average follow-up time was 10.78±11.0 months.All the patients finished the examination during the follow-up duration.The average intraocular pressure was(14.9±4.5)mmHg during the observation period.There were 38/69 (55.1%) functioning blebs and 31/69 (44.9%) non-function blebs under the slim lamp microscope.AS-OCT imaging showed diffuse-like blebs in 26 eyes (15.9%),cystic-like blebs in 11 eyes (27.5%),encapsulating-like blebs in 19 eyes (18.8%) and flatten-like in 13 eyes with the intraocular pressure of(13.16±3.77)mmHg,(15.36±2.92)mmHg,(15.77±5.07)mmHg and (16.62±5.33)mmHg,respectively,showing a significant difference among them (F=3.32,P<0.05).These patterns of different OCT presented a good consistency with the clinical outcome (χ~2=0.03,P=0.86).ConclusionAS-OCT allows the observation of filtering blebs after glaucoma surgery.It is probably to visualize the internal structure of filtering bleb and deep sclerectomy.Functional and dysfunctional filtering blebs delivery gives different OCT patterns.This could be a new way to assess the postoperative healing process.

Objective To observe features of twist of the left ventricle (LV) in patients of essential hypertension (EH) with LV normal geometry (LVN) by three-dimensional speckle tracking imaging (3D-STI).Methods Thirty EH patients with LVN and 32 healthy control subjects were included.From the dynamic images of LV apical two-and four-chamber-views and three-dimensional full volume dataset acquired,the following parameters were obtained:peak of LV basal,middle and apical segment rotation (Prot-B,Prot-M and Prot-A),peak of LV global segment twist (LV-tw) and rotation (LV-rot),the global radial and longitudinal displacement (Dr,Dl) and the global 3D displacement (D3d).The difference of these parameters was compared between EH and control groups,and the correlation between LV-tw and the displacements in EH group was studied.Results Compared with the normal control group,Prot-B,Prot-M,Prot-A,LV-tw,LV-rot,Dr,Dl and D3d of EH group were significantly increased (P < 0.01 or 0.05),and LV-tw showed significant correlation with Dr,Dl and D3d (P <0.01 or 0.05).Conclusions The evaluation of LV twist with 3DSTI in EH patients can reflect the changes of LV systolic function in early stage,3D-STI may provide a new modality for quantitative evaluation of early abnormality of LV function in clinical practice.

Objective To evaluate the feasibility and accuracy of full volume three-dimensional echocardiography(FV3DE) for quantifying the left ventricular volume in healthy fetuses. Methods Two hundred and twenty-two normal fetuses with gestational ages between 20 and 40 weeks were investigated. Full volume three-dimensional, two-dimensional (2D) and M-mode images were acquired by Philips iE33 system and data was processed offline using QLAB analysis software. Left ventricular end-systolic volume(ESV) and end-diastolic volume ( EDV) were measured using semiautomated border detection echocardiographic techniques, and compared with 2D biplane Simpson's method and M-mode Teichholz formula. Results Thirty-six fetuses with poor three-dimensional images and 5 twin pregnancies were excluded,the study subjects consisted of 181 singleton fetuses. The highest concordance correlation ( r =0.987 for EDV, r =0.988 for ESV) P <0. 001) was noted between 2D biplane Simpson's and FV3DE-derived values with a small bias (0. 332 ml for EDV,0. 135 ml for ESV). The Bland-Altman analysis showed that FV3DE had the best reproducibility than M-mode Teichholz formula and 2D biplane Simpson's method. Intra- and interobserver error of EDV were 2.85% and 4.22% for FV3DE,8.37% and 8.98% for 2D biplane Simpson's rule,30. 63% and 54. 70% for M-mode Teichholz formula. Intra- and interobserver error of ESV were 2.34% and 6. 14% for FV3DE,6. 26% and 11.7% for 2D biplane Simpson's rule,43.06% and 66.03% for M-mode Teichholz formula. Conclusions FV3DE is a novel technique that can be more accurate than conventional methods in quantification of fetal left ventricular volumes, it may provide new insight into evolving fetal cardiac structure and function.

Background Researches showed that microperimetry can exhibit more tiny visual function damage than conventional perimetry in glaucomatous eyes.However,the study on fixation stability of glaucoma is still rare until now.Objective This study was to compare the correlation between microperimetry Maia (Macular Integrity Assessment) and Humphrey perimetry,and to investigate the changes of the fixation stability in glaucoma patients with hemifield defect.Methods This study proposal was approved by Medical Ethic Committee of Peking University First Hospital.A cross-sectional study was performed under the informed consent of each subject.Thirtyfive eyes of 35 glaucoma patients with hemifield defect by 24-2 Humphrey perimetry were included in Peking University First Hospital from December 2013 to March 2014,and 30 eyes of 30 normal volunteers served as controls.Both Humphery (10-2) and Maia (expert 10-2) were performed on the subjects respectively and the correlation of the results between Humphery (10-2) and Maia (expert 10-2) were analyzed.Then the patients with normal hemifield on Humphrey were assigned to Maia normal group and Maia abnormal group.Fixation stability differences were compared between glaucoma group and normal control group,and between Maia normal group and Maia abnormal group.Results The moderately positive correlation was found in the mean sensitivity between Maia microperimetry and Humphrey perimetry (r=0.403,P =0.001),and the average threshold of Maia microperimetry was moderately positive correlated with the mean defect (MD) of Humphrey perimetry in glaucoma patients (r=0.438,P =0.008).The fixation stability parameter P1 was (67±17)% and (87±10)%,and that of P2 was (70±16)% and (88±9)%;the 63% bicurve elipse area (BCEA) was (5.08±1.55) °2and (2.21±0.60) °2,and the 95% BCEA was (14.74± 6.04) °2 and (2.86 ± 1.17)°2 in the glaucoma group and normal control group,respectively,showing significant decreases of P1 and P2 and increases of 63% BCEA and 95% BCEA in the glaucoma group compared with the normalcontrol group (t=-5.604,-4.831,9.885,11.086,all at P=0.000).In Maia normal group and Maia abnormal group,the P1 was (79±8)% and (63±17)%,the P2 was (81±10)% and (67±16)%,the 63% BCEA was (3.19±0.65)°2 and (5.70±1.22)°2 and the 95% BCEA was (9.10±2.60)°2 and (19.35±5.01)°2,respectively.Compared with the Maia normal group,the P1 and P2 were significantly lower,and 63% BCEA and 95 % BCEA were higher in the Maia abnormal group (t=-2.468,P=0.019;t=-2.371,P=0.024;t =5.514,P=0.000;t=5.575,P=0.000).Conclusions Maia microperimetry and Humphrey perimetry yield a good correlation for glaucomatous macular function examination.In addition,Maia microperimetry showed that fixation stability decreased in glaucoma patients with hemifield defect.
