Objective To study the efficacy of intubation on adults lacrimal duct obstruction with new generation silicon tube. Methods A retrospective non-random and non-control case series. Thirty-two patients (37 eyes) with lacrimal duct obstruction who had undergone intubation with new generation silicon tube were retrospectively reviewed in Department of Ophthalmology, the First Affiliated Hospital of Guangzhou Medical University. The mean duration of symptoms of epiphora was 16.3±3.8 months. All the patients were followed up at least 3 months after the tube removal. Success rates were evaluated by both symptoms of epiphora and syringing. Results Among 37 eyes, 26 of 37 (70.3%) were cured completely, 4 eyes were relieved in epiphora, 24 of 27 eyes (88.9%) were cured or relievedin simple lacrimal duct obstruction, 6 of 10 eyes (60.0%) was cured or relieved in dacryocystitis(P <0.05). The success rate for patients whose duration of symptoms of epiphora within 2 yearswas much higher thanthat whose duration of symptoms over 2 years(P <0.05). Conclusions It seems that the intubation using new generation silicon tube has a high success ratefor lacrimal duct obstruction, especially for early simple lacrimal duct obstruction.

Objective To evaluate the images of optic nerve in normal human volunteers using three-dimensional high resolution MRI and multiplanar reconstruction. Methods A total of 30 healthy volunteers underwent magnetic resonance imaging (MRI) with the sequences of 3D-VIBE and 3D-DESS. The axis and oblique sagittal images were obtained with multiplanar reconstruction. The quality of the images was analyzed, and the length of the optic nerve was measured on axis and oblique sagittal images. Results The anatomy of the optic nerve could be clearly displayed on both axial and oblique sagittal images. The full length of optic nerve was 43.48±2.60 mm on axial image and 42.10±3.16 mm on oblique sagittal image. The measured value of axial image was higher than that of oblique sagittal image (t=2.98, P <0.01). Conclusions High resolution MRI with multiplanar reconstruction can visualize the fine structure of the optic nerve, and facilitate to measure the length of optic nerve, it can provide a reliable method for the study of the anatomy and diseases of optic nerve.

Objective To investigate the association between ocular sensory dominance and interocular refractive error difference (IRED) based on the discrimination of Gabor signal in myopes. Methods From December 2014 to October 2015, 361 myopia subjects at Eye Hospital of Wenzhou Medical University were recruited. Among them, based on the asymmetry between interocular spherical equivalent (SE), 177 subjects were non-anisometropic (IRED≤1D), 184 subjects were anisometropic (IRED>1D).Ocular sensory dominance was measured with computer-based psychophysics techniques. Ocular Sensory Index (OSI) was recorded when a subject just detected the Gabor signal during each trial. T-test was used to compare the 50 OSI values collected from each eye, and the t-val-ue was used as a subject’s ocular dominance index (ODI). Results No significant differences were found in SE, J0 and J45 between non-anisometropic and anisometropic subjects. IRED in non-anisometropic and anisometropic subjects were-0.58±0.33D and-2.52±1.29D respectively, which had significant differences between them (Wilcoxon rank sum test, Z=-20.13, P <0.01). ODI in anisometropic subjects was 4.04±3.74, which was significantly higher than ODI (3.35±2.87) in non-anisometropic subjects (Wilcoxon rank sum test, Z=-2.08, P=0.04). In anisometropic subjects, the IRED was correlated with ODI (Pearson correlation analysis, R=0.39, P <0.01). What’s more, the dominant eyes were more myopic in these anisometropic subjects (sign-test, P <0.05). Conclusions The anisometropic myopes have stronger ocular dominance in comparison to non-anisometropic myopes. ODI in myopes with clear dominance is associated with IRED, and the dominant eyes are more myopic. Key words: Sensory dominance; Anisometropia; Psychophysics; Myopia
目的通过对近视眼Gabor信号的辨别，探讨眼感觉优势与眼间屈光差(IRED)的关系。方法选取2014年12月~ 2015年10月温州医科大学眼科医院近视患者361例。其中，根据眼间球当量(SE)的不对称性，177例受试者为非各向异性(IRED≤1D)， 184例受试者为各向异性(IRED>1D)。用基于计算机的心理物理技术测量眼感觉优势。在每次试验中，当受试者仅检测到Gabor信号时，记录眼球感觉指数(OSI)。采用t检验对每只眼睛采集的50个OSI值进行比较，并将t值作为受试者的眼优势指数(ODI)。结果非参差和参差受试者的SE、J0和J45无显著性差异。无参差和参差受试者的IRED分别为0.58±0.33D和2.52±1.29D，差异有统计学意义(Wilcoxon秩和检验，Z=-20.13, P <0.01)。各向异性受试者的ODI为4.04±3.74，显著高于非各向异性受试者的ODI(3.35±2.87)(Wilcoxon秩和检验，Z=-2.08, P=0.04)。在各向异性受试者中，IRED与ODI存在相关性(Pearson相关分析，R=0.39, P <0.01)。屈光参差者的主视眼近视程度更高(P <0.05)。结论屈光参差性近视比非屈光参差性近视具有更强的眼优势。显性近视的ODI与IRED相关，显性眼较近视。关键词:感觉优势;屈光参差症;心理物理学;近视

Objective To compare the effect of different fragmentation softening grids in femtosecond laser-assisted cataract surgery on cumulative dissipated energy (CDE), effective phacoemulsification time (EPT), balanced salt solution volume during surgery and corneal endothelial cell loss. Methods A prospective cohort study of all patients (66 cases, 75 eyes) who accepted femtosecond laser-assisted cataract surgery in Xiamen ophthalmic center during June 2015 to November 2015 were randomly divided into 3 groups: group A: Frag and Chop (350 mm fragmentation grids and octants); group B: Cylinder (diameter:3.0mm); group C: Chop (sestants). Patients were evaluated preoperatively with the Lens Opacities Classification System III (LOCS III). The CDE, EPT, balanced salt solution volume, corneal endothelial cell loss and best corrected visual acuity (BCVA) at one month were compared. Results There was no statistically significant difference in LOCS III, preoperative corneal endothelial cell count in three groups (P >0.05). Comparing with the group B and C, the CDE, EPT and postoperative corneal endothelial cell loss were significantly lower in group A (CDE: group A: 4.7±2.8, group B: 6.4±3.1, group C: 6.6±3.0; EPT: group A: 23.9±12.0s, group B: 30.8±11.7s, group C: 32.1±12.6s; corneal endothelial cell loss: group A: 4.2±4.3%, group B: 6.7±4.4%, group C: 7.2±4.8%; P 0.05). Conclusions The use of the femtosecond laser-assisted system in cataract surgery with frag and chop led to a statistically significant lower CDE, EPT and postoperative corneal endothelial cell loss.
