BACKGROUND Retinopathy is a serious complication related to prematurity and a leading cause of childhood blindness. The aggressive posterior form of retinopathy of prematurity (APROP) has a worse anatomical and functional outcome following laser therapy, as compared with the classic form of the disease. The main outcome measures are the APROP regression rate, structural outcomes, and complicati...

Purpose. To report the outcomes after primary intravitreal pegaptanib sodium in patients with diabetic macular edema (DME). Methods. We conduced a retrospective analysis of eyes with DME treated with primary intravitreal pegaptanib sodium (Macugen) (intravitreal pegaptanib group). The results were compared with the ones of eyes treated with intravitreal pegaptanib sodium associated with macular...

Comment There are three major problems in the endoscopic laser treatment of bleeding gastric cancer. Firstly, the tumour is often large, making coagulation of the entire surface impossible. Secondly, tumours may protrude into the lumen, making access to the distal surface of the lesion impossible. Finally, blood and clot in the stomach obscure the view. The possibility of using the laser at low...

INTRODUCTION Diabetic macular edema (DME) is a common cause of visual acuity deterioration among patients with diabetes. Laser photocoagulation still remains the most common treatment of DME and diabetic retinopathy. OBJECTIVES The aim of the study was to assess mean central retinal sensitivity among patients with DME before and after laser photocoagulation treatment. Additionally, we estimat...

Results are presented of a study to monitor the changes in the optical properties of breast tissue over a 12-month period after interstitial laser photocoagulation treatment of a fibroadenoma. The study involved generating cross-sectional images of the breast with a multichannel time-resolved imaging system and a nonlinear image reconstruction algorithm. Images of the internal absorbing and sca...

AIMS To estimate the effectiveness of diode laser photocoagulation of the retina posterior to the ridge in eyes with retinopathy of prematurity (ROP). METHODS Diode laser photocoagulation was applied posterior to the fibrovascular ridge in stage 4a ROP in six eyes of four infants and in advancing stage 3+ in two eyes of one infant. Seven eyes had previously been unsuccessfully treated with di...

Program Number: 6345 Poster Board Number: C0122 Presentation Time: 12:00 PM–1:45 PM Long-term results of laser photocoagulation sparing the papillomacular bundle for peripapillary polypoidal choroidal vasculopathy lesions Yukari Shirakata1, Fumio Shiraga2, Chieko Shiragami1, Ayana Yamashita1, Atsushi Fujiwara2. 1Ophthalmology, Kagawa University Faculty of Medicine, Kita-gun, Japan; 2Ophthalmolo...

AIM To identify if laser photocoagulation induces morphological changes specifically related to the choroidal capillary endothelial processes that protrude into Bruch's membrane. METHODS Two human eyes and one adult macaque monkey eye received retinal laser photocoagulation that was just suprathreshold, before enucleation or exenteration. They were examined by electron microscopy to determine...

PURPOSE To report the efficacy and safety of green laser photocoagulation for threshold retinopathy of prematurity (ROP). METHODS We reviewed the clinical records of the neonates who had undergone green laser photocoagulation for threshold ROP at the Federal University of Pernambuco in Brazil between January 2004 and January 2006. All procedures were conducted with local anesthetic drops. The...

PURPOSE To analyze the benefits, efficacy, and complications of the PASCAL((R)) photocoagulation laser system (OptiMedica, Santa Clara, CA, USA) in patients treated at our institution. METHODS We conducted a retrospective chart review of 19 patients (28 eyes) who underwent laser treatment using the PASCAL((R)) photocoagulation system from November 2006 to November 2007. These 28 eyes were div...
