International Eye Science 2014;(9):1689-1690
To investigate the curative effect of retaining the peripheral anterior lens capsule combined lensectomy with vitrectomy for ocular trauma.
●METHODS: Totally 33 patients ( 33 eyes ) with eye trauma underwent combined lensectomy with vitrectomy, retaining the peripheral anterior lens capsule and phase Ⅱposterior chamber lOL implantation. After follow - up of 6mo, visual acuity, intraocular pressure ( lOP ), lOL position, and intraoperative and postoperative complications were observed.
●RESULTS: Visions of all the patients were improved at varying degrees. After follow-up of 6mo, no obvious lens deflected and serious complications ( glaucoma, retinal detachment) appeared.
●CONCLUSlON: Combined lensectomy with vitrectomy, retaining the peripheral anterior lens capsule for ocular trauma has good curative effects of lessening complications during operation and postoperation and good visual acuity recovery.
3.Choroidal thickness and central serous chorioretinopathy:a case-control study and Meta-analysis
International Eye Science 2015;(8):1344-1349
AIM:To investigate the changes of subfoveal choroidal thickness ( SFCT ) in central serous chorioretinopathy ( CSCR) eyes and to compare them with normal control eyes.
METHODS: This was a case-control study and a Meta-analysis. Forty - six CSCR patients diagnosed by the fundus pre - set lens, fundus fluorescein angiography (FFA) and indocyanine green angiography (ICGA) were enrolled in this study. Sixty two age-, sex-, diopter- and axial length-matched 62 normal subjects ( 62 eyes ) were enrolled in this study as the control group. Using enhanced depth imaging optical coherence tomography ( EDI-OCT) , SFCT of CSCR eyes and normal control eyes were measured and compared. Univariate and multivariate linear regression analysis were performed to assess the association between SFCT and clinical factors. The Meta - analysis were conducted using the Stata software package to calculate the summary weighted mean differences ( WMDs) .
RESULTS:The mean SFCT of the CSCR group and the normal control group was 397. 34±83. 91μm and 274. 48±62. 57μm, respectively. The CSCR eyes had a thicker choroid than the control eyes at the SFCT (P<0. 01). Univariate and multivariable linear regression analysis showed that the SFCT was significantly thicker in association with the CSCR diagnosis. The result of our case-control study was consistent with the results of the further Meta-analysis with the pooled WMD of 156. 13μm (95% CI:137. 43, 174. 83) for SFCT.
CONCLUSION:Along with the comprehensive Meta-analysis, SFCT in CSCR eyes was thicker than that of normal control eyes. Increased SFCT might be associated with CSCR.

Objective To investigate the clinical incidence and influence of prostatic calculi on recalcitrant chronic abacterial prostatitis (CAP). Methods During August 2004 and March 2005, a total of 104 men with recalcitrant CAP refractory to multiple prior therapies were included in the study. Severity of symptoms in these patients was defined by the Chronic Prostatitis Symptom Index (CPSI). The detection and volume measurement of prostatic calculi, and the measurement of prostate volume were performed by ultrasonography. Associations between severity of symptoms and prostatic calculi were assessed using SNK ?2 tests and Spearman correlation. Results Prostatic calculi were detected in 58 of the 104 men (55.8%), including type Ⅱ calculi (larger, coarser) in 31.7% of cases. Mean patient age was significantly older in men with type Ⅰ calculi (small, multiple) than with type Ⅱ calculi or without calculus (P

AIM: To investigate the topography of the anterior surface of the human crystalline lens. ·METHODS: A Non-contact three-coodinate measuring system was utilized to scan the anterior surfaces of 8 human eye lenses in vitro. Acquired data were processed and computer models of the anterior lens surfaces were made using the program (Surfacer v 10.0). The to-pography of the anterior lens surfaces were established. Radii of curvature were measured at preset spots over the lens surfaces and two way analysis of variance was performed. The data were analysed to determine whether the radius of curvature varied systematically with the position on the lens surface from which the measurement was made. Lens surface asymmetric index (LSAI) was defined and calculated. The vertical and horizontal meridians of the modeled lens were calculated, and the best curve fit to any conic section was determined. ·RESULTS: The topography of the anterior lens surface indicated that the central zone (the central radius of curvature is (9.09±0.80)mm was steeper than that of the peripheral zone(17.05±2.20)mm. Two way analysis of variance of the radii of curvature at preset spots over the lens surfaces showed that the differences were statistically significant (P < 0.05). Curve regression of radii of curvature at preset spots and their distances to the surface center revealed that the correlation of them was the third power function. LSAI increased steadily from the lens surface center(0.013±0.005) to the periphery(0.184± 0.065). The dots on the horizontal and vertical meridians were fit to four kinds of curves, and the determinate coefficient of hyperbola fit were the largest (0.9989-0.9999). ·CONCLUSION: The anterior lens surface is imperfectly rotational symmetric. Moreover, the nearer to the center, the more rotational symmetric it is. Radii of curvature increase nonlinearly from the surface center to the periphery. Anterior lens surface is typically hyperbolic.
