Purpose: We compared the efficacy of sub-Tenon triamcinolone acetonide (STTA) to intravitreal triamcinolone aceto-nide (IVTA) injections during cataract surgery (CS) for patients with diabetic macular edema (DME).
Methods: The medical records of 33 eyes (26 patients) with DME which had undergone CS with STTA were compared to those of 34 eyes (27 patients) with DME which had undergone CS with IVTA. Central foveal thickness and best-corrected visual acuity (BCVA) were measured at the baseline and 1, 3, and 6 months after the surgery.
The purpose of this study was to determine the efficacy of one-year treatment of diabetic macular edema (DME) with intravitreal aflibercept (IVA) injections on a practical protocol. The medical records of 51 eyes of 43 patients who were diagnosed with DME and had received IVA treatments were reviewed. The best-corrected visual acuity (BCVA) and the central macular thickness (CMT) were measured at the baseline and at 1, 3, 6, and 12 months after the IVA.

The medical records of 49 eyes of 36 patients who were diagnosed with DME and had received IVR and 46 eyes of 40 patients who had received IVA treatment were reviewed. The central macular thickness (CMT) and best-corrected visual acuity (BCVA) were measured at the baseline and at 1, 3, and 6 months after the IVR or IVA.

Methods: The medical charts of 166 eyes of 161 patients who underwent vitrectomy for a MH were reviewed. The MH was not closed in 9 eyes of 9 patients after the initial surgery.
Background: The purpose of this study was to evaluate the effects of cataracts on the flicker electroretinograms (ERGs) recorded with the RETeval™ system under mydriatic-free conditions.
Methods: This was a retrospective study of 82 eyes of 60 patients with cataracts and 52 eyes of 38 patients who were pseudophakic. Flicker ERGs were recorded with the RETeval™ system (LKC Technologies, Gaithersburg, MD) under mydriatic-free condition with skin electrodes.
Purpose: To compare the effects of sub-Tenon's capsule triamcinolone acetonide (STTA) injection to that of STTA injection combined with microaneurysm photocoagulation (MAPC; STTA + MAPC) on eyes with diabetic macular edema (DME).
Patients And Methods: The medical records of 138 eyes of 138 patients with DME treated by either STTA or STTA + MAPC were reviewed. The degree of DME was determined by the optical coherence tomographic features: patients with serous retinal detachment (SRD+; 38 eyes) and patients without SRD (non-SRD; 100 eyes).
Purpose: To determine whether there are significant correlations between the N2 amplitude of the multifocal electroretinograms (mfERGs) and the retinal sensitivity and retinal nerve fiber layer (RNFL) thickness in glaucomatous and normal eyes.
Methods: Thirty-eight glaucomatous and 11 normal eyes were studied. The mfERGs were elicited by red stimuli presented on a blue background.
The purpose of this study is to identify the risk factors for a recurrence or persistence of diabetic macular oedema (DME) after a sub-Tenon's capsule triamcinolone acetonide (STTA) injection. The medical records of 124 patients (124 eyes) treated by STTA were reviewed. The age, sex, HbA1c level, best-corrected visual acuity, central macular thickness, insulin use, pioglitazone use, systemic hypertension, serous retinal detachment, proteinuria, panretinal photocoagulation, microaneurysm photocoagulation (MAPC), subthreshold micropulse diode laser photocoagulation (SMDLP), cataract surgery, and history of vitrectomy were examined by logistic regression analysis.

View Article and Find Full Text PDFPurpose: To compare the effect of posterior sub-Tenon's capsule triamcinolone acetonide (STTA) injection to that of pars plana vitrectomy (PPV) for diabetic macular edema (DME).
Patients And Methods: The medical records of 50 patients (52 eyes) with DME were reviewed. Twenty-six eyes underwent STTA (20 mg) and the other 26 eyes underwent vitrectomy combined with cataract surgery.
Purpose: To compare the surgical outcomes during pars plana vitrectomy (PPV) for diffuse diabetic macular edema (DME) with pretreatment to those without pretreatment.
Methods: The medical charts of 43 eyes of 46 patients who underwent PPV for DME were reviewed. The previously treated (Prev.
Purpose: To evaluate the microstructure of the inner and outer retina and the visual function after macular hole (MH) surgery using brilliant blue G (BBG) or indocyanine green (ICG) to make the internal limiting membrane (ILM) more visible.
Design: Comparative, retrospective, interventional case series.
Participants: Sixty-three eyes of 63 consecutive cases with MH were studied.
Purpose: To determine the relationship between the retinal thickness and sensitivity of the macular region after successful reattachment of an acute macula-off rhegmatogenous retinal detachment (RRD).
Methods: Twenty-three eyes of 23 patients with an acute macula-off RRD were studied (17 men, 6 women). The mean age of the patients was 53.
Purpose. To determine the factors associated with the development of a macular hole (MH) after successful rhegmatogenous retinal detachment (RRD) surgery. Methods.

Patients And Methods: On April 13 and 14, 2009, we performed IVB for consecutive 12 eyes of 12 patients in a sterile condition. Within two days after injection, blurred vision without ocular pain, anterior chamber inflammation, and vitreous opacity were developed in 6 of the eyes of 6 patients.
Purpose: The aim of our study was to determine the relationship between vision-related quality of life (VRQOL) following the National Eye Institute Visual Function Questionnaire-25 (NEI VFQ-25) and the macular sensitivity determined by microperimetry in patients with retinitis pigmentosa (RP).
Methods: The Japanese version of the NEI VFQ-25 was used to assess the VRQOL of 30 patients with typical RP whose decimal visual acuity was ≥0.6.
Background And Objective: To evaluate the efficacy of vitrectomy with simultaneous intravitreal injection of triamcinolone acetonide for macular edema associated with branch retinal vein occlusion.
Patients And Methods: A retrospective study of 45 eyes with macular edema associated with branch retinal vein occlusion. A posterior vitreous detachment was created and the vitreous cortex was completely removed, after which 23 eyes immediately had an intravitreal injection of triamcinolone acetonide (triamcinolone acetonide group) and 22 eyes did not (no triamcinolone acetonide group).
Aim: To compare the results of vitrectomy with internal limiting membrane (ILM) peeling to that without ILM peeling for macular edema associated with branch retinal vein occlusion (BRVO).
Methods: The medical records of 47 eyes of 47 patients with BRVO-associated macular edema were examined. To treat the macular edema, a posterior vitreous detachment (PVD) was created, and the ILM was removed in 13 eyes (ILM-removed group), whereas a PVD was created and the ILM was not removed in 34 eyes (ILM-preserved group).
Sodium azide (NaN(3)) is widely used in industry and agriculture, and also in laboratories as a potent preservative. NaN(3) induces cell death when applied to cultured cells. However, whether the mode of cell death is apoptosis or necrosis remains a subject of debate.

Methods: Ten eyes of 10 patients with CRVO underwent pars plana vitrectomy and RON. Standardized combined electroretinograms (ERGs) to full-field bright-flash stimuli were recorded preoperatively and, 3 months postoperatively.
Background: The sentinel node concept has become one of the most interesting topics in the treatment of head and neck cancer. The aim of this article is to report the results of our feasibility study and clinical application of sentinel lymph node (SLN) radiolocalization and biopsy in patients with clinically negative neck oral cancer.

The purpose of this study was to determine the morphological and functional changes in the macula after pars plana vitrectomy with the creation of a posterior vitreous detachment in eyes with diabetic macular edema (DME). A simple posterior vitreous detachment was created during pars plana vitrectomy accompanied by simultaneous cataract surgery in 19 eyes of 17 patients with DME. The visual acuity (log MAR units), multifocal electroretinograms (mfERGs), and optical coherence tomographically (OCT)-determined foveal thickness were determined preoperatively and at 6 months postoperatively.
