ABSTRACT
AIM:To evaluate the efficacy and safety of intravitreous injection of Conbercept for macular edema secondary to macular branch retinal vein occlusion(MBRVO).METHODS:Clinical records of 19 patients(19 eyes) who were diagnosed MBRVO with macular edema (ME) in our hospital,from July 2015 to September 2016 were retrospectively analysed.All patients were treated with an intravitreal dose of 0.5mg or 0.05mL conbercept ophthalmic injection by the 3+ pro re nata (PRN) project.All patients were evaluated by best corrected visual acuity (BCVA),central retinal thickness(CRT),the number of the injection,and the complications.RESULTS:During the 1,2,3 and 6mo after treatment the mean BCVA all improved significantly(P＜0.01),and the mean CRT reduced statistical significantly(P＜0.01);3 eyes had refractory ME,and micro-aneurysm leakage were identified by FFA,and the ME was suppressed effectively after local laser photocoagulation.No complications,such as secondary vitreous haemorrhage,retinal detachment,persistent high intraocular pressure and endophthalmitis were observed during subsequent follow-up.CONCLUSION:Intravitreous injection of conbercept for macular edema secondary to MBRVO may reduce macular edema and improve visual acuity effectively and safely in the short term.
ABSTRACT
AlM: To evaluate the effectiveness and security of lift and squeeze technique in phacoemulsification of hypermature cataract. METHODS: From June 2010 to June 2013, totally 156 eyes with hypermature cataract, which received phacoemulsification in our hospital, were enrolled. Lift and squeeze technique was used to chop the nucleus, and 1g/L Trypan blue was used for capsulorhexis. Average time of phaco complication, corneal edema and visual outcome were recorded. RESULTS: The best-corrected visual acuity ( BCVA ) was 0. 1-0. 4 in 15 eyes (9. 6%), 0. 5-0. 7 in 82 (52. 6%) eyes, and 0. 8-1. 0 in 59 ( 37. 8%) eyes at 3mo after surgery. The phaco time was 25-56s (average 42±10s), the maximum phaco power was 30%. Posterior capsular rupture and vitreous loss happened in 2 eyes (1. 3%), and the lOLs were implanted in the sulcus. Corneal edema classified at grade Ⅰ were seen in 12 eyes (7. 7%), and 5 eyes (3. 2%) at gradeⅡ, no eye at gradeⅢ and gradeⅣ. The mean endothelial cell loss was 8. 7%at 3mo. CONCLUSlON: Crystalline lens capsule staining with Trypan blue increase the success rate of intact continuous curvilinear capsulorhexis ( CCC ) . The lift and squeeze technique reduces the stress on the zonules and capsule, and decreases the phaco time and phaco power.
