A new technique for Nd:YAG laser posterior capsulotomy.

Aim: To investigate the effects of a new opening pattern in neodymium:yttrium-aluminum-garnet (Nd:YAG) laser posterior capsulotomy on visual function.

Methods: This technique was conducted along a circular pattern. The energy ranged between 0.

Strabismus following implantable anterior intraocular lens surgery.

Strabismus in adults is increasing and has recently become an important focus of attention due to the development of refractive surgery techniques. In this case, permanent strabismus developed in a woman with previous high myopia after implantable anterior intraocular lens surgery. An ophthalmologic examination revealed the presence of a lens which was placed slightly downward in relation to the center of visual axis in the anterior chambers and up-drawn pupils in both eyes.

Surgical outcome of mitomycin C-soaked collagen matrix implant in trabeculectomy.

Purpose: To assess the surgical outcomes and wound healing reaction of a filtering bleb after trabeculectomy using mitomycin C-soaked biodegradable collagen matrix (ologen).

Methods: Thirty eyes, in which the intraocular pressure (IOP) could not be controlled within the proper range by medication or laser treatment, were targeted in this study. After trabeculectomy with mitomycin C (0.

Acute vision loss associated with retinal circulatory disturbances after intravitreal injection of bevacizumab.

Purpose: Bevacizumab, a monoclonal antibody targeting vascular endothelial growth factor (VEGF), specifically binds to VEGF protein, and inhibits angiogenesis. Intravitreal/intracameral injection of bevacizumab has been reported as another treatment option for patients with various ocular ischemic conditions. However, we report 4 cases of acute vision loss after bevacizumab intravitreal injection.

Curcumin protects retinal pigment epithelial cells against oxidative stress via induction of heme oxygenase-1 expression and reduction of reactive oxygen.

Purpose: To determine whether curcumin induces expression of the defensive enzyme heme oxygenase-1 (HO-1) and protects cells against oxidative stress in cultured human retinal pigment epithelial cells.

Methods: Effective concentrations and toxicities of curcumin were determined after 3 h of curcumin treatment with the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay. Confluent human retinal pigment epithelium cell lines (ARPE-19) were preincubated with curcumin and oxidatively challenged with H(2)O(2).

Bilateral retrobulbar hemorrhage and visual loss following traumatic asphyxia.

Retrobulbar hemorrhage and permanent visual loss are rare presentations following traumatic asphyxia. In this case, bilateral permanent visual disturbance developed in a woman after chest-crushing trauma without direct trauma to the orbits. A computed tomography scan confirmed bilateral retrobulbar hemorrhages.

Changes in corneal endothelial cells after Ahmed glaucoma valve implantation: 2-year follow-up.

Purpose: To evaluate changes in corneal endothelial cells after Ahmed glaucoma valve (AGV) implantation for the treatment of refractory glaucoma.

Design: Observational case series.

Methods: We prospectively evaluated the change in density and shape of the corneal endothelium in 41 patients (41 eyes) who had undergone AGV implantation for the treatment of refractory glaucoma.

Changes in corneal endothelial cell density and morphology after Ahmed glaucoma valve implantation during the first year of follow up.

Purpose: To determine the effect of Ahmed glaucoma valve (AGV) implantation on corneal endothelial cells.

Methods: Ahmed glaucoma valves were implanted in 30 eyes of 30 patients with refractory glaucoma. Corneal endothelial cell density and shape was prospectively evaluated in both the subject and fellow eyes of each patient.
