1Retinal structural-vascular-functional relationship using optical coherence tomography and optical coherence tomography -angiography in myopia显示文摘Background:To examine the retinal structure–vascular-function relationship using optical coherence tomography(OCT)and optical coherence tomography angiography(OCTA)in myopia.Methods:This was a prospective cross-sectional study comprising 86 eyes of 45 individuals with varying axial lengths and spherical equivalents and no posterior segment abnormalities.All eyes underwent optical coherence tomography with the Spectralis SD-OCT and OCTA with RTVue-XR Avanti;Optovue.Individual macular retinal layer thicknesses and flow areas and vessel densities were measured on OCT and OCTA,respectively.Linear correlations were made between the macular layer thicknesses,flow areas and vessel densities with axial length,spherical equivalent and visual acuity.Results:The participants’mean ages were 33.34±14.45 years,mean spherical equivalent refractions were−7.17±5.71 D and axial lengths were 25.95±2.41 mm.There were significant positive correlations of foveal angle(r=0.757,p=0.001),inner retinal(r=0.764,p=0.001)and outer plexiform layer(r=0.771,p=0.001)thickness on OCT and vessel densities in deep capillary plexus(r=0.313,p=0.003)on OCTA with axial length and negative correlations with spherical equivalents and visual acuity.Significant negative correlations of outer nuclear layer(r=−0.560,p=0.03)and photoreceptor outer segment layer thickness(r=−0.856,p<0.001)were noted on OCT with axial length and positive correlations with spherical equivalents and visual acuity.Conclusion:The lateral retinal stretching in myopia could possibly explain the correlation between retinal layer thickness,vascular density and visual acuity in these eyes.Further research is required to investigate this.Ramesh Venkatesh Shivani Sinha Deepika Gangadharaiah Santosh G.K.Gadde Ashwin Mohan Rohit Shetty Naresh Kumar Yadav 2019Eye and Vision2019,6,1:7
2Comparison of extramedullary and intramedullary devices for treatment of subtrochanteric femoral fractures at tertiary level center显示文摘破裂正在质问的 subtrochanteric 和治疗形式的 ObjectiveThe 治疗并且植入常常正在演变。这研究试图与 subtrochanteric 破裂在相对年轻的 population.MethodsThirty 病人重游并且比较 extramedullary 对 intramedullary 设备与设备和后续继续的 extramedullary 或 intramedullary 被注册并且对待一个为病人的 clinico 放射学的 assessment.ResultsThe 平均数年龄的年是 37.53 年。最是在 21-40 岁之间的男性。损害的主导的模式是交通事故(66%) 。破裂根据 Russell-Taylor 分类被分类。百分之四十是 Russell-Taylor 类型 IA, 37% 类型 IB 和 23% 类型 IIA。外科的平均时间是从到医院的承认的时间的 3.6 天。外科的吝啬的持续时间是为 intramedullary 设备(组 A ) 的 45 分钟, 105 为 extramedullary 纪录设备(组 B ) 。平均的血损失是 100  在组 A 和 200   的 ml;在组 B 的 ml。意味着放射暴露的持续时间为组 A 和 B 是 130 秒和 140 秒,当医院停留的平均持续时间分别地是 12 天和 16 天时。优秀结果在组 A 在 47% 盒子中被看见,在组 B.ConclusionIntramedullary 设备的 33% 盒子是一可靠为 subtrochanteric 植入破裂。它与最小的软织物的损坏有联合的高率。Intramedullary 固定有生物并且 biomechanical 优点,而是手术技术上正在要求。渐渐的学习和耐心被需要做真正奖励的这个方法。Sanjay Yadav Shivendra Sinha Edwin Luther Naresh Chander Arora Manish Prasad Rohit Varma 2014Chinese Journal of Traumatology2014,17,3:2
3Quantifying microstructural changes in retinitis pigmentosa using spectral domain – optical coherence tomography显示文摘Background:Most patients of established retinitis pigmentosa(RP)have subnormal peripheral vision and heavily rely on central vision for their daily activities.Central visual acuity is dependent on photoreceptor survival at the macula.Identification of structural changes that precede visual loss is essential.The aim of this study was to correlate the Spectral Domain-Optical Coherence Tomography(SD-OCT)characteristics with visual acuity in patients with typical RP.Methods:This was a retrospective,observational case series of 224 eyes of 113 RP patients conducted a tertiary eye care center.SD-OCT imaging was done for all eyes.Central retinal thickness(CRT),photoreceptor outer segment length(PROS),foveal outer segment pigment epithelial thickness(FOSPET)and ellipsoid zone(EZ)extent were measured.A new variable,FOSPET-PROS ratio(FPR),obtained by dividing FOSPET by PROS is defined and correlated to corrected distance visual acuity(CDVA)in logMAR using linear regression.Results:Out of 113 patients,71 were males and 42 females.Mean age of the patients was 35.4±15.1 years.Mean CDVA was 0.33±0.25 logMAR with no difference between the genders.Mean CRT(218.74±83.5μm)and FPR(1.63±0.22)significantly correlated to CDVA with a correlation coefficient of r=−0.139(p=0.048)and r=0.842(p=0.0001),respectively.FOSPET(mean=71.15±13.8μm)and PROS(mean=44.85±12.5μm)did not show a significant correlation to CDVA,independent of FPR.Conclusions:Retinal microstructural changes on SD-OCT,especially the FPR,can be used as a surrogate marker to monitor disease progression in the central retina in degenerative diseases like RP.B.Poornachandra Aruj K.Khurana Preethi Sridharan Priyansha Chatterjee Chaitra Jayadev Naresh Kumar Yadav Rohit Shetty 2019Eye and Vision2019,6,1:1
