RESUMO
@#AIM: To analyze the correlation between subjective mean sensitivity and visual function <i>via</i> macular microperimetry.<p>METHODS: Totally 164 eyes of 127 patients with macular edema were involved in this study. According to different diseases, they were divided into 3 groups: age-related macular degeneration(AMD)(38 eyes), retinal vein occlusion(RVO)(43 eyes)and diabetic macular edema(83 eyes)groops. All patients underwent the examinations of optometry, optical coherence tomography scanner(OCT)and microperimeter. Correlation analysis was performed using Pearson, and <i>t</i>-test among groups.<p>RESULTS: Mean sensitivity(MS)values and fixation rate(P1, P2)of total patients with macular edema were significantly correlated with their BCVA, meanwhile the CRT was negatively correlated. MS values were significantly correlated with BCVA in AMD group, but the P1, P2 and CRT were not correlated. In DME and CRVO groups, MS values and P1, P2 were significantly correlated with BCVA, and CRTs were negatively correlated in DME but not correlated in CRVO. In BRVO group, MS values and CRTs were all not correlated with BCVA.<p>CONCLUSION:Microperimetry is probably a better subjective assessment for AMD macular function than OCT, and could be combined with OCT for function follow-up in DME and CRVO patients. For BRVO microperimetry might indicate certain macular dysfunction that could not be detected by VA or CCT. Microperimetry could be a subjective examination for the assessment of macular edema combined with OCT.
RESUMO
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.
