OBJECTIVE To investigate the response of retinal vessel diameters to photocoagulation treatment and their role for the success of laser treatment in patients with retinal vein occlusion. METHODS The study included 14 patients with branch vein occlusion or macular vein occlusion. The ophthalmologic examination included best-corrected visual acuity, biomicroscopy, fundus photography, and fluore...

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 hy...

BACKGROUND/AIMS A new real time monitoring system has been developed to locate the fixation point during juxtafoveal laser photocoagulation. METHOD The red diode laser beam is combined coaxially with the illumination beam to image a cross in the focal plane of the slit lamp, which allows projection of a red cross onto the patient's fundus. 27 patients with juxtafoveal choroidal neovascularisa...

Purpose: Transscleral diode retinal photocoagulation (diopexy) is becoming an accepted technique in the treatment of selected retinal diseases. The objective of this study is to evaluate diopexy technique in the production of adhesive chorioretinal lesions during the surgical treatment of the rhegmatogenous retinal detachment. Methods: 25 patients with rhegmatogenous retinal detachment were enr...

To report on an epithelial inclusion cyst of the iris that was successfully treated with needle aspiration and Ab externo laser photocoagulation. A 6-year-old boy was treated for a 6.0 mm fluid-filled cyst in the anterior chamber of the right eye. Thirteen months previously, he had undergone primary closure of a 6 mm full-thickness corneal laceration. The subsequent cyst was diagnosed as an epi...

BACKGROUND To introduce a new technique of laser-assisted conjunctival cystectomy using pattern scan laser (PASCAL) photocoagulation. CASE PRESENTATION A 50-years-old Asian woman presented with a conjunctival cyst in the left eye. Slit-lamp examination revealed a 5 mm × 2 mm sized freely movable conjunctival cyst. After a 1 mm × 1 mm sized conjunctival opening was made using PASCAL photocoagu...

Xenon photocoagulation burns in the rabbit fundus were studied angiographically with fluorescein labelled dextrans of molecular weights in the range 3000 to 150 000. Recent photocoagulation burns showed dye leakage to all molecular weights used. Angiograms 2 days after burns had been produced showed leakage of dextrans of molecular weights up to and including 70 000 but no leakage of dextran of...

Objective: The study aimed to evaluate the efficacy of the 980 nm diode laser and Er:YAG laser for photocoagulation treatment of oral and maxillofacial hemangioma and vascular malformations. Material and Methods: Seventy consecutive patients with either hemangioma or low-flow vascular malformations of the head and neck treated with laser photocoagulation were comprised in the study. Results: Lo...

PURPOSE To evaluate the efficacy of combination pars plana vitrectomy, endoscopic peripheral panretinal photocoagulation, and endocyclophotocoagulation (ECP) as compared with standard care in patients with neovascular glaucoma. METHODS This age-matched case-controlled retrospective series of 54 eyes compared the clinical outcomes between a consecutive series of combination pars plana vitrecto...

PURPOSE The aim of the present study was to investigate the effect of subthreshold diode laser micropulse (SDM) in comparison with conventional laser photocoagulation in the treatment of the diabetic macular edema (DME). METHODS Sixty-eight eyes from 68 patients with clinically significant DME were divided randomly into two equal groups. In the first group, SDM photocoagulation was employed, ...
