The incidence of endophthalmitis after vitrectomy is extremely low,especially lower in silicone oil-filled eyes.Silicone oil exerts a toxic effect on the cell membranes of microorganisms and leads to the lack of nutrients.It is thus believed to inhibit the growth of bacteria and fungi.Endophthalmitis induced by mixed bacteria in silicone oil-filled eye has been rarely reported.We reviewed the clinical manifestations,diagnosis,and treatment of a patient with endophthalmitis caused by mixed infection of

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.

BACKGROUNDSympathetic ophthalmia (SO), a rare, bilateral, diffuse granulomatous uveitis, usually occurs after open globe injury or intraocular surgery. We sought to identify the risk factors for the development of SO after open globe injury and describe their demographic and clinical features and outcomes of treatments.

METHODSA retrospective study of inpatients with globe injury in 15 tertiary referral hospitals of China from January 2001 to December 2005 was conducted. The information of demography, nature and mechanism of injury, time and ways of treatments and outcomes was reviewed. Diagnosis of SO was made based on a history of ocular trauma or surgery and subsequent development of bilateral or contralateral uveitis consistent with SO. Any association between related parameters and development of SO was analyzed.

RESULTSAmong 9103 patients (9776 eyes) of globe injury, SO occurred after open globe injury in 18 cases with an occurrence rate of 0.37%, vitrectomy of closed globe injury in 2 (0.37%) and perforation of burned eyes in another 2. For open globe injury, the median age ((36.72 +/- 13.59) years, P = 0.01) was higher in patients with SO; there were no significant effects of sexes, injury type, uvea proplaps, once or multi-intraocular surgery, once or multi-vitrectomy and endophthalmitis on incidence of SO; 0.70% endophthalmitis concurred with SO; 83.33% of SO occurred within 1 year after injury or last ocular surgery. SO developed in a fellow eye one week after evisceration of the perforating burned eye. Good final visual acuity was obtained in sympathizing eyes with prompt treatment.

CONCLUSIONSFor open globe injuries, SO sufferers were relatively older and any injury type could induce SO with equal possibility. The initial open globe injury was more likely to be the trigger of SO than subsequent intraocular surgeries including vitrectomy. Prophylactic enucleation after injury is not recommended.

To describe the clinical and optical coherence tomography (OCT) features of a macular hole (MH) or its precursor lesion in patients treated with systemic antiestrogen agents. We reviewed the medical history of the patient, ophthalmic examination, and both fundus and OCT findings. Three female patients receiving antiestrogen therapy sought treatment for visual disturbance. All of the patients showed foveal cystic changes with outer retinal defect upon OCT. Visual improvement was achieved through surgery for the treatment of MH in two patients. Antiestrogen therapy may result in MH or its precursor lesion, in addition to perifoveal refractile deposits. OCT examination would be helpful for early detection in such cases.

The effects of hemocoagulase in injectable form (hemocoagulating enzymatic fraction of South American snake Bothrops jararaca venom provided by Ravizza) on the control of intraocular bleeding during vitreous surgery were evaluated in rabbit eyes. Intraocular infusion solution with hemocoagulase (1 NIH thrombin unit/100 ml of BSS plus) significantly reduced the bleeding time. Electroretinogram b-wave and electroretinogram c-wave showed no abnormality. Infusate with hemocoagulase (1 NIH thrombin unit/100 ml of BSS plus) is not toxic to retinal tissue and appeared to be a useful agent for the control of intraocular bleeding during vitreous surgery.

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: 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.
