25G compared with 20G vitrectomy under Resight non-contact wide-angle lenses for Terson syndrome

Abstract

Abstract. The aim of the present study was to compare the effectiveness of 25G vitrectomy to standard 20G vitrectomy for treatment of Terson syndrome under Resight non-contact wide-angle lenses. This was a case-control study of 20 patients with Terson syndrome (study group) that underwent 25G vitrectomy under Resight non-contact wide-angle lenses, with those of 20 matched patients that underwent 20G vitrectomy (control group). Medical records were reviewed from between July 2011 and October 2013. Data included results of the Early Treatment Diabetic Retinopathy Study examination, ophthalmology B-scan ultrasonography and fundus photography. The mean age, follow-up time, the preoperative visual acuity of LogMAR and the preoperative intraocular pressure (IOP) were all comparable in the two groups (all P>0.05). There were statistically significant differences in postoperative visual acuity of LogMAR compared with preoperative visual acuity (P<0.001) in both groups, but no difference between the groups (P=0.845). However, the operative times (13.5 min in study group vs. 42 min in control group) and post-operative IOP at day 1 (13.5 vs. 20 mmHg) were significantly reduced in the study group compared to the control group (P<0.001). Therefore, the present findings suggest that 25G Vitrectomy for Terson syndrome under Resight non-contact wide-angle lenses can achieve a significantly shorter operative time and lower post-operative IOP compared with 20G Vitrectomy.

Clinical features and visual prognostic indicators after vitrectomy for Terson syndrome

“…In children, the data were comparable to those of adults, in that subhyaloid haemorrhage and subILM were found in one eye (3.6%), subILMs were found in five eyes (17.9%), subretinal haemorrhage was found in one eye (4%), and submacular haemorrhage was found in two eyes (7%) [20]. Epiretinal membranes were reported in 15-59% of patients [7,10,12,21,22]. In this case series, 19 eyes (35.2%) had epiretinal membranes.…”

A Case of Intraocular Cilium after 25-Gauge Micro-Incision Vitrectomy Surgery

“…The viewing angle can be adjusted by the surgeons without directly moving the microscope by changing the distance between the front lens and the corneal surface. It has been suggested by some reports that shorter operation times and improved surgical outcomes can be achieved by the use of a noncontact WAVS, such as the Resight system, which provides better fundus visibility including the peripheral areas with eye rotation [19, 20].…”
