RESUMO
Objective To assess the clinical outcomes about the visual qulitity of toric implantable contact lens ( TICL) implantation for high myopia with astigmatism. Methods Fifty-two eyes of 27 patients that underwent TICL implantation were examined. Uncorrected visual acuity( UCVA) ,best corrected visual acuity( BCVA) ,refraction,contrast sensitivity ( CS) with and without glare were evaluated before and after the treatment. Results Significant improvement in UCVA and BCVA were found at 1 month and 6 months after treatment (P0. 05), and the astigmatism at 1 month ( -0. 35 ± 0. 60)D and 6 months ( -0. 31 ± 0. 42)D after treatment were of no significant difference either (P>0. 05). The CS with and without glare were all significantly better than results before operation for 6. 0,12. 0 and 18. 0 cycles/degree (P0. 05). No significant difference were found preoperatively,1 month after treatment and 6 months after treatment in terms of CS with and without glare (P>0. 05). The satisfaction of this investigation was 100%. Conclusion The TICL performed well in correcting high myopia with astigmatism,and it is a good surgical option for the treatment.
RESUMO
Objective To observe whether form-deprivation myopia/amblyopia could protect retinal microvascular system and postpone the development of diabetic retinopathy. Methods The form-deprivation myopia/amblyopia was established combined with hyperglycemia mouse model,and the retinal vascular endothelial cells and pericytes were counted. Results Endothelial cells/ pericytes ratio in hyperglyce-mia group is significantly lower than that in normal group and form-deprivation myopia/amblyopia combined with hyperglycemia group. Con-clusion Form-deprivation myopia/amblyopia combined with hyperglycemia mice have more pericytes than hyperglycemia mice.
RESUMO
Authors defined the concept of drug packaging wastes,and analyzed the current administration of such waste recycling in China.With reference to experiences of other countries and Taiwan,the paper proposed to refine the legal framework for recycling drug packaging waste in China,by categorizing to set up the categorized recycling mechanism,and by refining the process to build the reverse logistics recycling system.
