Objective To explore the surgical techniques, efficacy and the management of complicated ocular trauma with anteriorposterior segment complications such as cyclodialysis.Methods Fifty-five patients (55 eyes) with complicated ocular trauma were enrolled in this study. Among them, there were 35 cases with eyeball contusion and 20 cases of eyeball rupture. Preoperative visual acuity was from no light perception to 0.15, intraocular pressure (IOP) ranged from one to 10 mm Hg(1 mm Hg=0.133 kPa）.Cyclodialysis, vitreous hemorrhage or retinal detachment were revealed by B-ultrasound and ultrasound biomicroscopy (UBM). Cyclodialysis clefts ranged from one to 12 clockhours. All patients underwent 3-port pars plana vitrectomy with gas/silicone oil tamponade and ciliary body reattachment by cryotherapy (cyclodialysis cleftsle;three clock-hours) or suture fixation (cyclodialysis clefts＞three clockhours). Healing after surgical trauma, visual acuity, intraocular pressure, intraocular hemorrhage, ciliary body and retinal reattachment were followed up.Results In one month after surgery, UBM showed 54 patients out of 55 patients had good ciliary body reattachment. Gonioscopy revealed cyclodialysis still existed in one patient, and this was cured by a second surgical suture fixation. In three months after surgery, ocular trauma healed in all 55 patients, the visual acuity ranged from no light perception to 0.15, with a best corrected visual acuity of 0.8. The ciliary body and retina had good reattachment. IOP of 52 patients was normal; IOP of three patients was still lower than 10 mm Hg. Three patients had secondary glaucoma which was treated by glaucoma surgery. Conclusions Complicated ocular trauma with cyclodialysis can be treated with vitrectomy and cryotherapy or transscleral sutures. The procedure is safe and effective.
Objective To observe the incidence of ciliary detachment and its relationship with intraocular hypotension soon after vitrectomy. Methods A total of 46 eyes of 46 patients who underwent vitrectomy were examined by ultrasound biomicroscope (UBM). The patients were divided into three groups according to different tamponade: gas group (11 eyes), silicone oil group (8 eyes) and balanced saline solution (BSS) group (27 eyes). Basing on the postoperative intraocular pressure (IOP), the patients were divided into two groups: IOPlt; 10 mm Hg (25 eyes) and IOPge;10 mm Hg (21 eyes). UBM was applied to determine the tomographic features of the ciliary body 3 days after the surgery. IOP were monitored by noncontact tonometer daily after the surgery. The eyes with ciliary detachment were then examined once a week till the ciliary detachment reattached. The followup period was from 14 to 35 days. Results After vitrectomy, ciliary detachment was observed in 20 eyes of 46 eyes (43.5%), The incidence of ciliary detachment was 27.3％ in gas group, 25.0％ in silicone oil group, and 55.6％in BSS group. The average IOP in eyes with ciliary detachment ［(6.47plusmn;4.49) mm Hg （1 mm Hg=0.133 kPa）］ was significantly lower than that in the eyes without ciliary detachmen ［(15.61plusmn;7.72) mm Hg］ (t=8.031,Plt;0.001). The incidence of ciliary detachment was higher in eyes with postoperative IOP lt;10 mm Hg (68.0％) than that in the eyes with postoperative IOP ge;10 mm Hg (14.3%) (chi;2＝15.60, Plt;0.001). All eyes with postoperative ciliary detachment got spontaneous reattachment within 30 days after the surgery except that one eye had optic disc edema due to severe intraocular hypotension. Conclusions Early postoperative ciliary detachment is a common complication after vitrectomy. Eyes filled with BSS have the highest incidence of postoperative ciliary detachment. Most of the patients with ciliary detachment may get spontaneous reattahment within 30 days after the surgery.
Objective To investigate the clinical manifestations and possible reasons of the missed and inaccurate diagnosis of Fuchs syndrome. Methods The clinical data of 85 patients with Fuchs syndrome who were diagnosed and treated from June 1999 to December 2003 were retrospectively analyzed. The disease history of each patient was carefully recorded. Slit-lamp microscopy was performed on the patients. The character and distribution of keratic precipitates (KP), color of the iris, depigmentation, and complications were noted in detail. The data recorded in other hospitals were analyzed and the reasons of missed and inaccurate diagnosis were statistically analyzed. Results The age of the patients ranged from 13 to 72 years, and binocular involvement was noted in 76 patients. None of the patients showed ciliary congestion and iris synechiae. Middle-sized or stellated KP was found. Triangle-distributed KP was seen in 13 patients, and diffuse distribution behind the corneal or in the pupil area was in 72. Anterior-chamber flare was observed in all of the patients, while anterior-chamber cells were only noted in 42 patients. The iris with different degrees of depigmentation was found in all the patients. Complicated cataract and increased intraocular pressure occured in 44 and 19 patients, respectively. The diagnosis in other hospitals mainly included uveitis, anterior uveitis and complicated cataract. Conclusions Fuchs syndrome is characterized by depigmented iris and typical KP. Missed and inaccurate diagnosis is mainly due to the unawareness of its clinical features. (Chin J Ocul Fundus Dis, 2005, 21: 360-362)
