METHODS：NTG patients ...AIM：To compare the corneal biomechanical properties difference by ocular response analyzer（ORA） in normal tension glaucoma（NTG） patients with different visual field（VF） progression speed. METHODS：NTG patients with well-controlled Goldmann applanation tonometer（GAT） who routinely consulted Kitasato University Hospital Glaucoma Department between January 2010 and February 2014 were enrolled.GAT and ORA parameters including corneal compensated intraocular pressure（lOPcc）,Goldmann estimated intraocular pressure（lOPg）,corneal hysteresis（CH）,corneal resistance factor（CRF） were recorded.VF was tested by Swedish interactive threshold algorithm（SITA）-standard 30-2 fields.All patients underwent VF measurement regularly and GAT did not exceed 15 mm Hg at any time during the 3y follow up.Patients were divided into four groups according to VF change over 3y,and ORA findings were compared between the upper 25th percentile group（slow progression group） and the lower 25th percentile group（rapid progression group）.RESULTS：Eighty-two eyes of 56 patients were studied.There were 21 eyes（21 patients） each in rapid and slow progression groups respectively.GAT,lOPcc,lOPg,CH,CRF were 12.1＋1.4 mm Hg,15.8±1.8 mm Hg,12.8±2.0 mm Hg,8.4±1.1 mm Hg,7.9±1.3 mm Hg respectively in rapid progression group and 11.5±1.3 mm Hg,13.5±2.1 mm Hg,11.2±1.6 mm Hg,9.3±1.1 mm Hg,8.2±0.9 mm Hg respectively in slow progression group（P=0.214,〈0.001,0.007,0.017,0.413,respectively）.In bivariate correlation analysis,lOPcc,lOPcc-GAT and CH were significant correlated with m△MD（r =-0.292,-0.312,0.228 respectively,P =0.008,0.004,0.039 respectively）.CONCLUSION：Relatively rapid VF progression occurred in NTG patients whose lOPcc are rather high,CH are rather low and the difference between lOPcc and GAT are relatively large.Higher lOPcc and lower CH are associated with VF progression in NTG patients.This study suggests that GAT measures might underestimate the IOP in such patients.展开更多

METHODS： This prospective, comparative, observational study recruited patients into two groups. Group 1 was the control group including normal subjects except those with cataracts （cataract group, n=67 eyes of 67 patients）, and group 2 was NTG group including patients who were diagnosed with NTG and cataracts （n=43 eyes of 43 patients）, which were treated with phacoemulsification and intraocular lens implantation. Before surgery, and at postoperative 1 and 6too, anterior chamber angles were evaluated by SS-OCT under dark conditions using three- dimensional angle analysis scan protocol. Angle opening distance （AOD）, angle recess area （ARA）, and trabecular- iris surface area （TISA） at four quadrants （temporal, nasal, superior, and inferior） were calculated automatically by SS-OGT, after the observer marked scleral spurs. RESULTS： A total of 106 patients （54 males and 52 females） were enrolled in the study. Angle parameters, AOD, ARA, and TISA were increased after surgery in both groups. However, changes of angle parameters were only significant in group 2. In group 2, preoperative lOP was 13.2＋2.9 mm Hg, and postoperative lOP at 1 and 6mo were 10.5＋3.0 and 10.7＋2.8 mm Hg, respectively. In group 1, preoperative lOP was 12.42.8 mm Hg, and postoperative lOP at 1 and 6mo were 11.6＋2.5 and 12.0＋2.8 mm Hg, respectively. After cataract surgery, angle parameters changed significantly while IOP significantly reduced and was maintained in group 2 （P〈0.001）. The changes in angle parameters （＆AOD500, ATISAS00 at temporal; ＆AOD500, S, RA500 at nasal） were linearly correlated with postoperative IOP changes. CONCLUSION： Cataract surgery may have improved antedor chamber angle parameters and decreased lOP in NTG patients.展开更多

Methods The variations of lOP were measured in 216 eyes of suspected OAG patients at 4-hour intervals for 48 h. Based on the results of the serial lOP measurements, optic disc changed and visual field defected, the patients were diagnosed as primary OAG （ POAG ）, normal tension glaucoma （NTG）, ocular hypertension （ OHT） , or physiologic cup （PC）. Results After the serial lOP measurements, 16. 7% of the suspected OAG patients were diagnosed as POAG, 32. 4% as NTG, 24. 5% as OHT, and 26. 4% as PC. The highest percentages of the POAG group had peak lOP at 8 AM （19. 4% ） and their trough lOP at 10 PM （27. 8% ） ; the NTG group had peak lOP at 12 AM （18. 6% ） and their trough lOP at 12 PM （22. 9% ） ; the OHT group had peak lOP at 4 AM （22. 6% ） and their trough lOP at 10 PM （26. 4% ） ; and the PC group had peak lOP at 4 AM （ 21. 1% ） and their trough lOP at 12 PM （ 21. 1% ）. The percentages of peak lOP outside clinic （ 8 AM - 4 PM） in the POAG, NTG, OHT and PC groups were 55. 6%, 50. 0%, 58. 4% and 45. 7%, respectively. The mean magnitude of variance was 5. 1 - 6. 7 mmHg in those suspected OAG patients. There was a strong positive correlation in lOP between both eyes at each time point of measurement and the variation curves of the right and left eyes had parallel profiles in those suspected OAG patients. Conclusion Serial measurement of lOP is still needed, in order not to miss the peak and the trough lOP readings in suspected OAG patients, which helps in better management of glaucoma.展开更多
