PURPOSE: The 2.2-mm microincision cataract surgery and small-gauge vitrectomy system is known to result in less surgically-induced astigmatism (SIA) in comparison to conventional surgical methods. We compared the amounts of SIA after combined phacoemulsification and 23-gauge transconjunctival sutureless vitrectomy (23G-TSV) using the 2.2-mm microincision and 2.75-mm standard incision methods. METHODS: We studied 59 patients (61 eyes) who underwent combined phacoemulsification and 23G-TSV from November 2008 to September 2012. Twenty-eight patients (28 eyes) underwent 2.2-mm microincision coaxial phacoemulsification, and 31 patients (33 eyes) underwent 2.75-mm standard incision phacoemulsification. SIA was evaluated using Naeser's polar method with the simulated keratometric values obtained from corneal topography. Preoperative and 1-week and 1-month postoperative KP (Naeser's polar value along the specific axis) and DeltaKP values were compared between the 2.2-mm microincision and 2.75-mm standard incision groups. RESULTS: One week after surgery, both groups exhibited similar amounts of SIA (-DeltaKP[120], 0.40 +/- 0.41 vs. 0.51 +/- 0.56 diopters [D]; p = 0.390). One month after surgery, however, the amount of SIA was significantly smaller in the 2.2-mm microincision group as compared to the 2.75-mm standard incision group (-DeltaKP[120], 0.31 +/- 0.54 vs. 0.56 +/- 0.42 D; p = 0.045). CONCLUSIONS: In combined phacoemulsification with 23G-TSV, 2.2-mm microincision coaxial phacoemulsification induces less SIA than does 2.75-mm standard coaxial phacoemulsification.

BACKGROUNDBleb-associated endophthalmitis (BAE) is a rare but severe complication of trabeculectomy with poor outcome. Various surgical methods were explored to treat such patients. However, there is no defined protocol. The aim of this study was to describe a new combined operation, and to demonstrate the outcome of the treatment.

METHODSNine patients with BAE were enrolled in our study. The combined operation including pars plana vitrectomy (PPV), sclera patch graft (SPG) and endoscopic cyclophotocoagulation (ECP) was used to treat these patients.

RESULTSIn the follow-up of 18 - 24 months, all patients with the endophthalmitis were cured, the useful visual acuity was preserved in 7 patients, and the intraocular pressure (IOP) of 8 patients was controlled just after first operation, only one needed another trans-scleral cyclophotocoagulation.

CONCLUSIONThis combined operation is a useful method for treating the patients with BAE, with SPG and vitrectomy to control the endophthalmitis and ECP to balance the postoperative IOP.

PURPOSE: To determine sequential intraocular pressure (IOP) changes after pars plana vitrectomy (PPV) with or without combined phacoemulsification and intraocular lens implantation (PE & IOL). METHODS: Consecutive patients who underwent PPV with PE & IOL (combined group) or without PE & IOL (vitrectomy group) were reviewed for postoperative sequential IOPs and the number of IOP lowering medications used. Of the 68 patients (68 eyes) who underwent simple PPV, 41 eyes were allocated to the vitrectomy group, and 27 eyes to the combined group. RESULTS: The mean IOPs were higher on postoperative days one and two, as compared to preoperative values, in both groups. The mean IOP changes on postoperative day one (10.0 mmHg vs. 5.3 mmHg, p = 0.02) and day two (3.7 mmHg vs. 1.3 mmHg, p = 0.02) were significantly higher in the combined group. CONCLUSIONS: Phacovitrectomy is associated with a higher risk of IOP elevation during the early postoperative period than PPV alone. Caution should be exercised in patients who are vulnerable to IOP fluctuations when combined surgery is indicated.

A 58-year-old man admitted to our opthalmology department with the complaint of branch retinal vein occlusion. He was treated with intravitreal Ozurdex in the right eye. Two days after the injection, the patient presented with ocular pain and the visual acuity was hand movement. A diagnosis of endophthalmitis was made. We performed emergent pars plana vitrectomy (PPV) and the implant was removed from the vitreous cavity using a retinal forceps. A combination of vancomycin 1.0 mg and amikacin 0.4 mg was injected intravitreally. However, because of the blurring in the vitreus one week after the procedure, phacoemulsification and a repeat PPV was performed. Five days after the last procedure the signs and symptoms of endophthalmitis were resolved. Our case demonstrated that endophthalmitis could develop after intravitreal implantation of Ozurdex. Surgical removal of the implant and immediate vitrectomy seems to be a useful treatment option in these cases.

PURPOSE: To report the experiences at our institute of pars plana vitrectomy (PPV) in combination with intravitreal triamcinolone acetonide (IVTA) injection in patients with retained lens material after cataract surgery. METHODS: The medical records of patients who underwent PPV between January 2005 and December 2006 after complicated cataract surgery in which lens material was dropped into the vitreous cavity were reviewed retrospectively. RESULTS: Five eyes of five patients were treated by vitrectomy and removal of the dislocated lens material and were administered an adjuvant intravitreal injection of 4 mg triamcinolone acetonide at the end of surgery. IVTA administration induced a rapid improvement in vision within six weeks postoperatively. Final visual acuity was 20/32 or better in all patients. Inflammatory cystoid macular edema (CME) that existed preoperatively was promptly improved after IVTA. Intraocular pressure increased transiently in one patient. No procedure-related complications were observed. CONCLUSIONS: PPV with additional IVTA was successfully performed in five eyes with retained lens material and resulted in a marked resolution of vitreous inflammation, an improvement in CME and rapid visual recovery. The authors recommend that IVTA administration should be investigated more thoroughly as an adjunct during the management of retained lens material.

A 60-year-old diabetic patient transferred to our retina clinic for a regular follow-up for diabetic retinopathy. He had uneventful cataract surgery at the time of pars plana vitrectomy in the right eye due to diabetic retinopathy at a private ophthalmologic hospital. Six months after the surgery, neovascular glaucoma with hyphema developed in the right eye and an Ahmed valve was implanted at our hospital. Ten months after cataract surgery, we found opacification of the intraocular lens (IOL) which was causing significant visual disturbance. At the time, the best corrected visual acuity (BCVA) in the right eye was hand motion. The IOL was explanted 45 months after the operation. Five months after explantation, the BCVA was 0.06. Unfortunately, pathologic analysis was not performed. Patient-related factors such as an anterior chamber reaction caused by hyphema might have been responsible for the opacification. To our knowledge, there are no previous reports of opacification of the Akreos Adapt IOL.

PURPOSE: This study was designed to evaluate the efficacy of fluid-gas exchange for the treatment of postvitrectomy retinal detachment. METHODS: We retrospectively reviewed the records of 33 consecutive patients (35 eyes) who underwent fluid-gas exchange treatment for postvitrectomy retinal detachment using the two-needle pars plana approach technique. RESULTS: The retinal reattachment rate was 80.0% after complete intravitreal gas disappearance following the fluid-gas exchange; the overall success rate was 65.7%. Visual acuity was improved or stable in 80.0% of cases; a two-line or greater vision improvement or a best-corrected visual acuity of 0.4 or better occurred in 62.9% of cases. The success rates for superior retinal detachments and posterior pole retinal detachments were 76.5% and 85.7%, respectively. CONCLUSIONS: Fluid-gas exchange represents a simple and cost-effective alternative outpatient procedure for retinal reattachment without reoperation for the treatment of superior and posterior pole retinal detachments.

PURPOSE: To report a case of bilateral spontaneous anterior lens dislocation associated with retinitis pigmentosa (RP). METHODS: A 45-year-old male with RP presented with elevated intraocular pressure (IOP) in the right eye and was treated with laser iridotomy (LI). After LI, complete crystalline lens dislocation into the anterior chamber occurred. Surgical intervention, including anterior vitrectomy, intracapsular cataract extraction (ICCE), and IOL scleral fixation was performed. Two years later, the same episode occurred in his left eye and a similar treatment was done. RESULTS: Surgery was successful in both eyes. CONCLUSIONS: This is the first report of bilateral spontaneous anterior lens dislocation in a RP patient.

This prospective observational case series study included 6 eyes of 6 consecutive glaucomatous patients. Each patient underwent trabeculectomy with mitomycin C, and received a 1.25 mg of subconjunctival bevacizumab injection at completion of the trabeculectomy. Study eyes included two with neovascular glaucoma, three with uveitic glaucoma, and one with secondary glaucoma following vitrectomy. All eyes had undergone failed glaucoma laser/surgical treatment or an intraocular surgical procedure. Intraocular pressure (IOP) at the following postoperative visits: preoperative, 1 week, 1 month, 2 months, 3 months, and 6 months, was measured. We also evaluated postoperative bleb findings and complications. IOP measured at each visit was 37.5+/-14.4 mmHg, 6.2+/-3.4 mmHg, 8.3+/-7.2 mmHg, 12.0+/-4.4 mmHg, 10.8+/-3.1 mmHg, and 12.2+/-3.3 mmHg, respectively, for each visit. All eyes had functioning blebs with normal IOP at postoperative 6 months with no additional IOP-lowering medication.
