PURPOSE: To investigate the clinical outcomes of combined vitrectomy and intrascleral fixation of a new posterior chamber intraocular lens (PC IOL) as a treatment for IOL dislocation. METHODS: We conducted a retrospective interventional study at our medical facility from January 2015 to January 2017. Posteriorly dislocated IOLs were removed with pars plana vitrectomy. Two intrascleral tunnels, 2.0 mm in length, were created 1.5 mm to the limbus at 6 and 12 o'clock positions. Both haptics of new foldable acrylic 3-piece IOLs were inserted into the tunnel until the IOL was secured in a central position. We analyzed the preexisting ocular condition, visual acuity (VA), and refractive error preoperatively and postoperatively, and recorded postoperative complications. RESULTS: Forty-nine patients (50 eyes) were enrolled in the study. The mean follow-up period was 12.8 ± 6.6 months. A best-corrected VA of 6/12 or better was achieved in 43 eyes (86%). The mean VA significantly improved from 0.32 logarithm of the minimum angle of resolution (logMAR) at baseline to 0.18 logMAR at last follow-up (p = 0.03). The refractive status after intrascleral fixation of the PC IOL revealed a mean hyperopic shift of +1.09 ± 1.28 diopters from the predicted spherical equivalent. Postoperative vitreous hemorrhages occurred in six cases and were cleared without visual compromise. Cystoid macular edema was well-controlled by topical nonsteroidal anti-inflammatory drugs (NSAID) medications in two cases. In two cases, IOL dislocation recurred and required re-operation. There were no serious adverse events of suture-related complications, retinal detachment, corneal compromise, or endophthalmitis in any of the patients. CONCLUSIONS: Our data revealed that use of combined vitrectomy and intrascleral fixation of PC IOLs is a safe and efficient technique to correct IOL dislocation. We observed good visual outcomes with only minor complications.

PURPOSE: To report a case of ocular perforation by an acupuncture needle directly through the bulbar conjunctiva. CASE SUMMARY: A 62-year-old male visited our clinic with acute ocular pain and decreased vision in his left eye. He had received intraocular acupuncture therapy one day earlier. A slit-lamp examination revealed conjunctival hyperemia and vitreous prolapse at the superonasal quadrant of the bulbar conjunctiva. Grade one of anterior chamber cells was found in the left eye. Dilated fundoscopy revealed three retinal hemorrhages at the superonasal quadrant of the retina; vitreous hemorrhage and opacity were also observed. Thus, vitrectomy and injections of intravitreal antibiotics were performed. Intraoperatively, we identified the entry site, located in the superonasal retinal quadrant, immediately behind the ora serratia. At the three-month postoperative follow-up, the patient's visual acuity was 0.9 in the left eye and the retina remained flat with no postoperative complications. CONCLUSIONS: We observed a case of ocular perforation and endophthalmitis following ocular acupuncture treatment. This case illustrates the dangers of intraocular acupuncture therapy.

PURPOSE: To evaluate 25-gauge transconjunctival sutureless vitrectomy for primary repair of rhegmatogenous retinal detachment (RRD). METHODS: We performed a retrospective study of 46 consecutive eyes of 46 patients who underwent 25-gauge transconjunctival sutureless vitrectomy to repair primary RRD. Outcome measures included single surgery anatomical success rate, final anatomical success rate, postoperative visual acuity, and surgical complications. RESULTS: Forty eyes were phakic and six eyes were pseudophakic. Twenty-six eyes had superior quadrant retinal tear, 12 eyes had inferior quadrant tear and eight eyes had both. The mean operation time was 56.3 minutes. The single surgery anatomical success rate was 93.48% (43/46). Two eyes with recurrent retinal detachment underwent fluid gas exchange: one received barrier laser treatment in the outpatient clinic, and the other underwent reoperation; the final success rate was 100%. The best corrected visual acuity improved from 1.34 log MAR to 0.48 log MAR (p < 0.01) in macula - off patients (30 eyes) and from 0.32 log MAR to 0.07 log MAR (p = 0.279) in macula - on patients (16 eyes). Postoperative complications included wound leaking (two eyes), cataract progression (13 eyes), vitreous hemorrhage (one eye), transient hypotony (one eye), and increased intraocular pressure (seven eyes). CONCLUSIONS: Primary repair of RRD using 25-gauge transconjunctival vitrectomy resulted in an excellent final anatomical success rate and postoperative visual outcomes.

OBJECTIVETo examine the prognosis of preretinal hemorrhage following vitrectomy and silicone oil tamponade for severe proliferative diabetic retinopathy.

METHODSClinical data of 76 cases of proliferative diabetic retinopathy treated with vitrectomy and silicone oil infusion tamponade in Sir Run Run Shaw Hospital from October 2006 to September 2013 were retrospectively reviewed. Intraoperative bleeding,postoperative preretinal bleeding,blood reabsorption time, and preretinal fibrosis were assessed.

RESULTSAll preretinal hemorrhage developed within 1 week after surgery, blood was distributed in thin and scattered patterns (32 cases), thick and localized patterns (25 cases) or thick and scattered patterns (19 cases). The preretinal hemorrhage was ceased in 1 day after operation in 35 cases, in 2 days after operation in 18 cases, in two weeks after operation in 23 case. Recurrent hemorrhage occurred within 1 week after operation in 15 cases. Thin blood was largely reabsorbed in about two weeks, and thick blood was largely reabsorbed in about five weeks. Fibrosis tissue was resulted in 15 cases(34.1%) with thick blood.

CONCLUSIONMost of preretinal hemorrhage occurs within 1 week after surgery and is reabsorpted with 5 weeks in patients with proliferative diabetic retinopathy undergoing vitrectomy and silicone oil tamponade. The major complication of preretinal bleeding is the formation of preretinal fibrosis.

BACKGROUNDNeovascular glaucoma (NVG) is a refractory glaucoma. The management of NVG is very difficult, and it is more difficult when combined with vitreous hemorrhage. The aim of this study was to investigate the effects of ranibizumab plus combined surgery for NVG with vitreous hemorrhage.

METHODSA total of 26 eyes of 26 NVG patients with vitreous hemorrhage were recruited in this study. The patients aged from 36 to 63 years with a mean age of 51.97 ± 7.60 years. The mean intraocular pressure (IOP) was 46.38 ± 5.75 mmHg (1 mmHg = 0.133 kPa) while being treated with the maximum medical therapy. The mean best-corrected visual acuities converted to logarithm of the minimum angle of resolution (logMAR BCVA) was 2.62 ± 0.43. All the patients underwent intravitreal injection of 0.5 mg (0.05 ml) ranibizumab combined with pars plana vitrectomy (PPV), pars plana lensectomy (PPL) with a preserved anterior capsule, panretinal photocoagulation (PRP), and trabeculectomy (intravitreal ranibizumab [IVR] + PPV + PPL + PRP + trabeculectomy). The IOP and logMAR BCVA were the main outcome measures in this study.

RESULTSThe follow-up period was 12 months. The mean postoperative IOPs were 26.38 ± 3.75 mmHg, 21.36 ± 3.32 mmHg, 18.57 ± 3.21 mmHg, and 16.68 ± 2.96 mmHg, respectively at 7 days, 1 month, 3 months, and 12 months after PPV + PPL + PRP + trabeculectomy. At the last follow-up, the mean IOP was significantly lower than the preoperative one (t = 6.612, P = 0.001). At 7 days, 1 month, 3 months, and 12 months after PPV + PPL + PRP + trabeculectomy, the mean logMAR BCVA were 1.30 ± 0.36, 1.29 ± 0.37, 1.29 ± 0.39, and 1.26 ± 0.29, respectively. At the last follow-up, the mean logMAR BCVA was significantly improved, and the difference was statistically significant compared with preoperative one (t = 6.133, P = 0.002). The logMAR BCVA improved in 22 eyes (84.62%), and remained stable in 4 eyes (15.38%). The neovascularization in the iris and the angle regressed significantly in all patients 7 days after ranibizumab injection. No serious complications occurred during 12 months of the study.

CONCLUSIONSIVR + PPV + PPL + PRP + trabeculectomy can control IOP well and improve BCVA without severe complication for NVG patients with vitreous hemorrhage.

PURPOSE: To evaluate the complication incidence of 23-gauge pars plana vitrectomy day surgery. METHODS: A retrospective review was conducted on 79 eyes that underwent 23-gauge pars plana vitrectomy day surgery from September 2009 to September 2010. The main outcome measures included changes in best corrected visual acuity (BCVA), intraocular pressure (IOP), and presence of postoperative complications after the day surgery. RESULTS: The mean preoperative log MAR BCVA improved from 1.32 +/- 0.96 to 0.40 +/- 0.41 at 3 months after surgery (p < 0.05). There was no significant differences between the mean preoperative IOP and IOP on the 1st day after surgery (p > 0.05). At the end of surgery, suture placement was required for sclerotomy site leakage in 4 eyes (5.1%). There were 10 eyes (12.7%) with postoperative complications, including 7 eyes with increased IOP (8.9%), hypotony in 2 eyes (2.6%) and vitreous hemorrhage in 1 eye (1.3%), with no case requiring reoperation. CONCLUSIONS: The patients who underwent 23-gauge pars plana vitrectomy day surgery achieved visual improvement without serious complications postoperatively.

PURPOSE: To investigate the results of 23-gauge sutureless vitrectomy and preoperative bevacizumab in diabetic retinopathy cases. METHODS: A total of 212 eyes received pars plana vitrectomy by a single surgeon for proliferative diabetic retinopathy and were followed up for at least 6 months. The change of visual acuity and operative complications among the 20-gauge vitrectomy (group I, 86 eyes), 23-gauge vitrectomy (group II, 30 eyes), and 23-gauge vitrectomy with preoperative intravitreal bevacizumab (IVB) injection (group III, 96 eyes) were retrospectively analyzed. RESULTS: One month postoperatively, visual improvement was better in groups II and III than in group I. Three months postoperatively, visual improvement was better in group III than in groups I and II. Six months postoperatively, visual improvement in group III was better than in group I, but there was no significant difference between group II and III. Intraoperative retinal breaks and postoperative vitreous hemorrhage were less common in group III than in groups I and II. CONCLUSIONS: In patients with proliferative diabetic retinopathy, 23-gauge sutureless vitrectomy showed faster visual recovery compared with 20-gauge vitrectomy, and vitrectomy with preoperative bevacizumab had less intraoperative and postoperative complications than vitrectomy without preoperative bevacizumab.

PURPOSE: To evaluate the efficacy and long-term prognosis of pars plana vitrectomy and Ahmed valve implantation for intractable glaucoma comorbid with retinal disorders. METHODS: A retrospective review of 34 eyes of 30 patients receiving pars plana vitrectomy and Ahmed valve implantation for intractable glaucoma comorbid with retinal disorders was performed. Preoperative and postoperative intraocular pressure (IOP) and visual acuity, the usage of IOP-lowering medications and postoperative complications, and surgical success rate were evaluated. RESULTS: IOP and the number of IOP-lowering medications showed a significant decrease after pars plana vitrectomy and Ahmed valve implantation, as compared to before surgery (p < 0.001). The success rate was 88%, 88%, 84% and 85% postoperatively at 1 month, 6 months, 1 year and 3 years respectively. The mean follow up period was 24.21 +/- 14.99 months. Complications related to surgery included hyphema in 2 eyes, recurrent corneal epithelial erosion and defect in 2 eyes, corneal ulcer in 2 eyes and vitreous hemorrhage in 4 eyes. Visual acuity improved in 14 eyes (41.1%), no changes in 13 eyes (38.2%) and decreased in 7 eyes (20.6%). CONCLUSIONS: Pars plana vitrectomy and Ahmed valve implantation for intractable glaucoma comorbid with retinal disorders show long-term efficacy in lowering IOP.

We report a case of bilateral peripheral retinal neovascularization and chronic idiopathic myelofibrosis in a 69-year-old man. Ophthalmic examination revealed peripheral retinal nonperfusion with retinal neovascularization in both eyes and vitreous hemorrhage in the right eye. Fluorescein angiography of both eyes showed a marked midperipheral and peripheral avascular retina temporally with arteriovenous anastomosis and sea-fan neovascularizations. Blood tests showed pancytopenia and teardrop-shaped red blood cells, and bone marrow examination showed hypocellular marrow with severe fibrosis. The neovascularization was regressed following pars plana vitrectomy in the right eye and scatter laser photocoagulation in the left. The results suggest that peripheral retinal vessel occlusion and neovascularization may be associated with idiopathic myelofibrosis.
