| 1 | Stereopsis after Implantation of Intraocular Lens in Patients under 40 Years Old with Unilateral Cataract显示文摘Purpose:.To investigate the stereopsis after single focus intraocular lens (SIOL) implantation in patients aged < 40 years with unilateral cataract. Methods: In total, 36 patients (36 eyes) were divided into emmetropia and myopia groups. Twenty seven subjects with good uncorrected distance visual acuity (UCDVA) after surgery were enrolled in the emmetropia group..The myopia group consisted of 9 subjects whose one eye had mild myopia postoperatively and the other was emmetropic or myopic. Visual acuity,.distance and near stereoacuity were measured post-operatively. Results:.In the emmetropia group,.uncorrected near visual acuity (UCNVA) did not differ significantly between eyes (t=1.87,P>0.05)..The LogMAR UCNVA of the operated and fellow eyes were (0.71±0.12) and (-0.05±0.07, t=28.4,P< 0.001) respectively..Distance stereoacuity was 60';.the near stereoacuity with uncorrected visual acuity and BCNVA in the operated eyes were 200' and 30' respectively (Z=-4.121,P< 0.001). In the myopia group,.the BCDVA did not differ significantly between the operated and fellow eyes (t=-0.636,P > 0.05)..The UCNVA of the operated eyes (0.18±0.12) was significantly better compared with that of the fellow eyes(-0.04±0.10,.t=4.2252,.P<0.001)..The distance stereoacuity with uncorrected visual acuity and BCDVA in the operated eyes were 200' and 60' respectively (Z =-2.371,P<0.05). The near stereoacuity with uncorrected visual acuity was 50'. Conclusion:For patients with unilateral cataract aged<40 years, stereopsis is closely associated with refractive status after IOL implantation..Near stereoacuity in emmetropic eyes can be improved with refraction,.and that in mildly myopic eyes can be enhanced by leaving myopia uncorrected. | Shuke Luo Zhende Lin | 2012 | Eye Science2012，27，2： | 1 |
| 2 | Comparison of the Mydriatic Effects of Mydrin-P and Compound Tropicamide in the Screening of Retinopathy of Prematurity显示文摘Purpose: To observe and compare the effects of pupil dilation between Mydrin-P and compound tropicamide in the screening of retinopathy of prematurity.Methods:.The right eyes of premature infants received Mydrin-P eye drops as the treatment group, whereas the left eyes were administered with compound tropicamide as the control group..The eye drops were delivered every 5 min for three times..The pupil size was observed and recorded at 10,.15,and 20 min after administering mydriasis.Results:.The mean pupil diameter did not significantly differ between the treatment and control groups at 10.(6.24 ±0.72 mm vs. 6.24±0.68 mm, t=0.00, P=1.00), 15(6.83±0.55 mm vs. 6.78±0.54 mm, t=1.75, P=0.083) or 20 min(7.22±0.40 mm vs. 7.15±0.50 mm, t=1.62, P=0.109), respectively. However, the mean pupil size at any two time points significantly differed in both groups(all P<0.001).Conclusion: Both Mydrin-P and compound tropicamide exert similar clinical efficacy in the screening of retinopathy of prematurity..The most appropriate time for screening was at 20 min after mydriasis. | Shuke Luo Zhonghe Wan Xiaofang Yin Zuke Ye Yan Lu | 2014 | Eye Science2014，29，4： | 0 |
