International Eye Science.2017;17(6):1139-1142.

AIM:To observe the efficacy of intravitreal conbercept injection for chronic central serous chorioretinopathy (CSC).METHODS: Nine eyes of 9 patients diagnosed as chronic CSC between October 2015 to May 2016 were treated with an intravitreal injection of conbercept (0.5mg/0.05mL) (six patients were given the same does of intravitreal injection again at 1mo after the first injection).Follow-up observation was at 1, 2, and 6mo after injection.Observed indicators included best-corrected visual acuity (BCVA), intraocular pressure, optical coherence tomography (OCT), fundus fluorescein angiography (FFA), choroidal indocyanine green angiography (ICGA), macular fovea thickness (CMT), subfoveal choroidal thickness (SFCT).RESULTS:Seven of the 9 patients responded significantly to the drug, while 2 patients had no response.The CMT was 373.12±72.43μm at baseline, which decreased significantly to 332.05±67.13μm, 282.24±62.30μm and 225.56±71.08μm at 1, 2 and 6mo after the intravitreal injection.The mean thickness of SFCT was 422.11±64.82μm before treatment.The choroidal thickness of non-responsive patients before treatment was below average, respectively 353μm and 365μm.The SFCT of 1, 2, and 6mo after treatment was 391.45±75.24μm, 365.53±63.07μm, 355.40±66.65μm.Before treatment and 1mo after, there was no significant difference (P=0.074), but there was statistically significant (P<0.01) between those of before and 2mo and 6mo after.The mean BCVA of the prior treatment was 0.53±0.32, the after treatment was 0.65±0.20, there was no different between the two(P>0.05).CONCLUSION: Intravitreal conbercept injection in chronic CSC may have some effect in accelerating subertinal fluid resolution and decreasing the CMT.The SFCT within 6mo after treatment was significantly lower than pretreatment.The SFCT may be an indicator of whether patients respond.

International Eye Science.2017;17(6):1105-1107. doi:10.3980/j.issn.1672-5123.2017.6.24

AIM: To observe the clinical efficiency of intravitreal conbercept on diabetic macular edema(DME).METHODS: This was a single arm, open-babel prospective study.Twenty eyes from 20 patients (12 males and 8 females) with DME diagnosed by fundus fluorescein angiography (FFA) and optical coherence tomography (OCT) were enrolled.Before the injection, best-corrected visual acuity (BCVA) of early treatment of diabetic retinopathy study (ETDRS), non-contact tonometer, ophthalmoscope, fundus photography, fundus fluoresein angiograph (FFA), and OCT were examined.All affected eyes were treated with intravitreal conbercept 0.05mL (10mg/mL).Patients were followed up for 6 to 11mo, with a mean duration of 8.55±1.96mo.Post-treatment BCVA, CMT, leakage of macular edema and complications were compared with baseline using repeat analysis.RESULTS: The initial average visual acuity (ETDRS letters) were 43.35±17.45, range from 9 to 70.The initial average central macular thickness (CMT) was 576.30±167.92μm, range from 337 to 987μm.The mean BCVA showed significant improvement during 1, 3, 6mo post-treatment and the latest follow up, with a mean increase of 11.2±5.9, 13.8±7.9, 15.7±6.8 and 14.7±8.6, respectively (P<0.01).The changes of BCVA between before and at 1mo after treatment were different compared with the changes between before and at 6mo (P<0.01).During the latest follow up, the mean BCVA was obviously improved in 10 eyes (50%), improved in 7 eyes (35%), stable in 3 eyes (15%).Likewise, the mean CMT significantly decreased during the follow-up period with a mean CMT reduction of 183.8±159.5, 292.9±169.0, 271.4±167.2 and 286.4±166.9μm respectively (P<0.001).The CMT at 1mo were different with that 3, 6mo and final follow-up (P<0.01).During the latest follow up, macula lutea leakage disappeared in 6 eyes (30%), decreased in 12 eyes (60%) and increased in 2 eyes (10%).No adverse events such as secondary retinal detachment or endophthalmitis were found during the follow-up.CONCLUSION: Intravitreal conbercept significantly improve visual acuity and macular edema exudation.

Kai, GONG ; Yun, XIE ; Yuan, YUAN ; Wei, WANG

International Eye Science.2017;17(6):1102-1104. doi:10.3980/j.issn.1672-5123.2017.6.23

AIM:To analyze the accuracy and the influencing factors of LAMBDA100 retinometer in predicting the visual acuity of cataract patients with high axial myopia after phacoemulsification.METHODS: The retinal visual acuity was measured in 91 patients with 91 cataract eyes by LAMBDA100, and compared with the best corrected visual acuity 2wk after operations.If differences of predictive visual acuity and postoperative visual acuity between the two logarithmic visual acuity chart was within 2 lines, it was considered consistent.RESULTS: The total compliance rate was 62%, the false positive rate was 2%,the false negative rate was 36%.The predictive accuracy was affected by lens opacity, the deeper opacity, the lower accuracy.The predictive accuracy of eye with axial length ≥32mm was significantly lower than that of eye with axial length <32mm, the difference was statistically significant (P<0.05).The predictive accuracy rate of group that preoperative best corrected visual acuity was ≥4.0 was 75%;the predictive accuracy rate of group that preoperative best corrected visual acuity was <4.0 was 49%, the difference was statistically significant (P<0.05).CONCLUSION: LAMBDA100 can be used as an assistant tool for predicting postoperative visual acuity in immature stage cataract of patients with high myopia.The eye axial length, the degree of visual acuity and lens opacity can influence the predicting accuracy.
