| 1 | Lens thickness assessment : anterior segment optical coherence tomography versus A-scan ultrasonography显示文摘AIM: To assess lens thickness measurements with anterior segment-optical coherence tomography(AS-OCT)in comparison with A-scan ultrasonography(A-scan US).·METHODS: There were 218 adult subjects(218 eyes)aged 59.2 ±9.2y enrolled in this prospective cross-sectional study. Forty-three eyes had open angles and 175 eyes had narrow angles. Routine ophthalmic exam was performed and nuclear opacity was graded using the Lens Opacities Classification System Ⅲ(LOCS Ⅲ). Lens thickness was measured by AS-OCT(Visante OCT, Carl Zeiss Meditec, Dublin, CA, USA). The highest quality image was selected for each eye and lens thickness was calculated using Image J software. Lens thickness was also measured by A-scan US.·RESULTS: Interclass correlations showed a value of99.7% for intra-visit measurements and 95.3% for inter-visit measurements. The mean lens thickness measured by AS-OCT was not significantly different from that of A-scan US(4.861 ±0.404 vs 4.866 ±0.351 mm, P =0.74).Lens thickness values obtained from the two instruments were highly correlated overall(Pearson correlation coefficient =0.81,P <0.001), and in all LOCS Ⅲ specific subgroups except in grade 5 of nuclear opacity. Bland-Altman analysis revealed a 95% limit of agreement from-0.45 to 0.46 mm. Lens thickness difference between the two instruments became smaller as the lens thickness increased and AS-OCT yielded smaller values than A-scan US in thicker lens(β=-0.29, P <0.001)· CONCLUSION: AS-OCT-derived lens thickness measurement is valid and comparable to the results obtained by A-scan US. It can be used as a reliable noncontact method for measuring lens thickness in adults with or without significant cataract. | Nikoo Hamzeh Sasan Moghimi Golshan Latifi Massood Mohammadi Nassim Khatibi Shan C.Lin | 2015 | International Journal of Ophthalmology(English edition)2015，8，6： | 2 |
| 2 | Supraciliary microstenting with phacoemulsification in patients with open-angle glaucoma and cataracts显示文摘Elevated intraocular pressure(IOP)is a major risk factor for the development or progression of glaucoma.Lowering IOP is the only proven therapeutic approach to the management of glaucoma.IOP can be lowered by medication,laser treatment or surgery(1).Generally,instillation of IOP- | Chungkwon Yoo Shan C.Lin | 2017 | Eye Science2017，32，1： | 0 |
| 3 | Individuals with and without normal tension glaucoma exhibit comparable performance on tests of cognitive function显示文摘AIM:To evaluate aspects of cognition impacted by individuals with and without normal tension glaucoma.METHODS:Fifty normal tension glaucoma(NTG)and 50 control patients≥50 y of age were recruited from the UCSF Department of Ophthalmology.Demographic data and glaucoma parameters were extracted from electronic medical records for both groups.Tests of executive function[Executive Abilities:Measures and Instruments for Neurobehavioral Evaluation and Research(EXAMINER)]and learning and memory[California Verbal Learning Test–Second Edition(CVLT-II)]were administered to both NTG and controls.Race,handedness,best-corrected visual acuity,maximum intraocular pressure,optic nerve cup-todisc ratio,visual field and optic nerve optical coherence tomography parameters,and a measure of general health(Charlson Comorbidity Index)were compared between NTG and controls as well as within NTG subgroups.Multivariate linear regression was used to compare group performances on the EXAMINER battery and CVLT-II while controlling for age,sex,and years of education.RESULTS:NTG and controls were comparable with respect to age,sex,race,education,handedness,and the Charlson Comorbidity Index(P>0.05 for all).Performance on the EXAMINER composite score and the CVLT-II did not differ between NTG and controls(P>0.05 for both).CONCLUSION:This is the first prospective study in which the cognitive function of subject with NTG were evaluated using a comprehensive,computerized neurocognitive battery.Subjects with NTG do not perform worse than unaffected controls on tests of executive function,learning,and memor y.Results do not suppor t the hypothesis that individuals with NTG are at higher risk for cognitive dysfunction and/or dementia. | Qi N.Cui David Green Mohit Jethi Todd Driver Travis C.Porco Jane Kuo Shan C.Lin Robert L.Stamper Ying Han Cynthia S.Chiu Saras Ramanathan Michael E.Ward Katherine Possin Yvonne Ou | 2021 | International Journal of Ophthalmology(English edition)2021，14，11： | 0 |
