The efficacy of micro-invasive vitrectomy for retinal detachment associated with choroidal detachment

Objective To observe the efficacy and safety of micro-invasive vitrectomy for retinal detachment associated with choroidal detachment.Methods A total of 35 patients (36 eyes) with retinal detachment associated with choroidal detachment were enrolled in this study.The patients included 22 males and 13 females,with a mean age of (51.32±17.34) years.Visual acuity was light perception in six eyes,hand movement in 12 eyes,finger counting in nine eyes,0.01 - 0.1 in eight eyes,and 0.2 - 0.3 in one eye.The median LogMAR visual acuity was (2.13±0.50).The median intraocular pressure was (7.08±2.62) mm Hg (1 mm Hg=0.133 kPa).All the patients were received vitrectomy using 23-gauge instrumentation combined with 25-gauge infusion.Tamponade with silicone oil (35 eyes) or C3F8 gas (one eye) were performed.The median follow-up time was (6.23 ± 3.07) months.The pre-and post-operative visual acuity,intraocular pressure,the rate of retinal reattachment,the rate of recurrent retinal detachment and complications were comparatively analyzed.Results Retinal reattachment was attained in 36 eyes (100％) at the first day after vitrectomy.Retinal reattachment was attained in 33 eyes (91.7 ％) and recurrent retinal local detachment was attained in three eyes (8.3 ％) at one months after vitrectomy.The rate of retinal reattachment was 83.3％ (30 eyes) at three months after vitrectomy.One day,one and three months after treatment,the mean LogMAR visual acuity were 1.77±0.66,1.53±0.72,1.31±0.77 respectively.The differences of the visual acuity was statistically significant between before and after vitrectomy (F=62.61,P＜0.05).One day,one and three months after treatment,the mean intraocular pressure were (12.47±7.28),(15.51±6.86),(15.82±7.60) mm Hg respectively.The differences of the intraocular pressure was statistically significant between before and after vitrectomy (F=6.88,P＜0.05).Secondary glaucoma occurred in one eye at three months after vitrectomy.Except this,there was no other complication related to treatment.Conclusion Micro-invasive vitrectomy is a feasible and safe treatment for retinal detachment with choroidal detachment.
