Abstract:
Objective To evaluate the efficacy and safety of modified intracystic ethanol irrigation for traumatic iris cyst eyes.Methods A retrospective analysis was designed.Twelve cases of traumatic iris cyst patients were observed from August 2016 to August 2018 in Xiamen Eye Centre of Xiamen University.After anterior chamber filled with DisCoVisc,cyst fluid was drained gently via a 30-gauge needle,and ethanol was irrigated into the cyst through 3-way T-extension until the cyst wall turned white.DisCoVisc was washed in the end.Patients were followed for cornea and anterior chamber condition,best-corrected visual acuity (BCVA),intraocular pressure (IOP) and endothelial cell density (ECD).The diameters of maximal length and width in maximal cross-sectional area were calculated by ultrasound biomicroscopy (UBM) preoperatively and postoperatively.The follow-up period was 3 to 24 months.Written informed consent was obtained from each patient before surgery.Results BCVA (LogMAR) and IOP had no significant changes after surgery in one week (t=1.30,P=0.22;t=-0.91,P=0.38).BCVA was elevated in 5 cases at the last follow-up,but declined in 3 cases,kept stable in 4 cases.Mean intensity of ECD before and 3 months after operation was (2 270.79±458.43)/mm2 and (2 111.52±483.46)/mm2,respectively,the mean loss of ECD was 159.27 cells/mm2,and there was a significant change between the two time points (t=3.76,P=0.00).Mean postoperative maximal length diameter before and 3 months after operation was (5.87±0.95)mm and (1.46±0.83) mm,mean postoperative maximal width diameter was (3.10 ±0.55) mm and (0.89 ±0.47) mm,respectively,the mean postoperative maximal length diameter was reduced by 5.33 mm,and the mean postoperative maximal width diameter was reduced by 2.22 mm,with significant changes between the two time points (t =18.55,P =0.00;t =11.75,P =0.00).All cysts were resolved and without recurrence at the last follow-up.No significant complications,such as cornea endothelial decompensation,endophthalmitis,sympathetic ophthalmia and retinal detachment were seen during the follow-up period.Conclusions Modified intracystic ethanol irrigation is a safe and effective procedure to treat traumatic iris cysts,which is more simple with less injury and low rate of complications.
