ABSTRACT
@#AIM: To evaluate the one-year outcome of intravitreal conbercept injections for the treatment of choroidal neovascularization secondary to pathological myopia(pm-CNV)by optical coherence tomography angiography(OCTA).<p>METHODS: The medical records of 26 consecutive eyes of 23 patients who received intravitreal injections of conbercept for pm-CNV with a follow-up of 1y were retrospectively reviewed. All the patients were diagnosed by fundus fluorescein angiography(FFA)and OCTA at the first visit. All approaches were performed as “1+PRN” treatment. Outcomes included best-corrected visual acuity(BCVA), central foveal thickness(CFT)and the mean CNV area by OCTA.<p>RESULTS: Mean BCVA improved from(0.66±0.51)at baseline to(0.39±0.38)at 1y(<i>t</i>=3.528, <i>P</i>=0.004). The CFT before treatment and after 1y after were(275.08±48.74)μm and(205.15±43.74)μm respectively(<i>t</i>=4.630, <i>P</i>=0.001). The mean pm-CNV areas before treatment and after 1y treatment were(0.48±0.24)mm<sup>2</sup> and(0.15±0.11)mm<sup>2</sup> respectively, with a significant difference among them(<i>t</i>=5.329, <i>P</i>=0.000). Twenty-one eyes had no needs after the first treatment. Four eyes received 2 injections and only one eye received 3 injections. No severe adverse events were noted relevant to the therapy.<p>CONCLUSION: Intravitreal conbercept can improve the vision and relieve CFT and CNV area for the treatment of pm-CNV with “1+PRN” by OCTA for 1y, however, long-term follow-up still need to be performed.
ABSTRACT
Objective To evaluate the effectiveness and safety of modified scleral tunnel for the prevention of Ahmed valve tube exposure in Ahmed valve implantation for refractory glaucoma.Methods A retrospective study was conducted in 72 patients with Ahmed glaucoma valve implantation for refractory glaucoma.All the patients were divided into unmodified and modified scleral tunnel group.In the unmodified scleral tunnel group,38 patients (38 eyes) underwent traditional scleral tunnel in Ahmed valve implantation,while in the modified scleral tunnel group,34 patients (34 eyes) received modified scleral tunnel in the procedures.The changes in intraocular pressure and visual acuity after operation were observed,and the incidence of drainage tube exposure and other complications were compared between the two methods after Ahmed valve implantation.The patients were followed up for 6 to 36 months with an average of 18 months.Results The intraocular pressure was (16.30 ±5.73) mmHg (1kPa =7.5 mmHg) in the unmodified scleral tunnel group and (15.80 ± 6.12)mmHg in the modified scleral tunnel group,with no significant difference between the two groups (P ＞ 0.05),but there was significant difference with the preoperative data (48.4 ± 5.79) mmHg (P ＜ 0.01).During the follow-up,conjunctival tube exposure was seen in 3 eyes (7.9％) in the unmodified scleral tunnel group,whereas there was no tube exposure in the modified scleral tunnel group.Conclusion The modified scleral tunnel is capable to prevent conjunctival tube exposure in patients with refractory glaucoma,which is more efficient and safe than traditional scleral tunnel in Ahmed glaucoma valve implantation.
ABSTRACT
Human body often contacts with different kinds of pathogens,but these pathogens do not result in disease due to innate immunity.The adaptive immunity is able to discriminate self and non-self pathogen and further maintain immunological health and appropriate response through peripheral regulatory mechanism.Whether innate immune or adaptive immune,lack of control mechanism leads to autoimmunity and autoinflammation.Up to now,some studies demonstrated that autoimmunity and autoinflammation have many common characteristics in intraocular inflammation,but their mechanism relates to different molecular pathways.Hence,ophthalmologists have better understanding in the pathogenesis of uveitis.Herein,it is inferred from the basic mechanism of the activation of immunology pathway that regulation of innate and adaptive immunity might impact how autoinflammatory and autoimmune pathways contribute to disease progress in uveitis.
