Background: To assess the effectiveness of repeated transvaginal ultrasound-guided ovarian interstitial laser treatment in the management of anovulatory patients with polycystic ovary syndrome (PCOS). Materials and Methods: A retrospective study was performed in our department on 27 anovulatory PCOS women who failed to respond to the first ultrasound-guided transvaginal ovarian interstitial las...

Objective: To describe results of barrier laser photocoagulation in preventing progression of recurrent retinal detachment. Methodology: Prospective review of five patients with recurrent retinal detachment confined to the peripheral inferior retina. Three rows of barrier argon laser photocoagulation of moderate intensity white burns were performed. Patients were observed carefully after laser ...

We report the results of a prospective study of 23 patients in which interstitial laser photocoagulation (ILP) was used to treat an osteoid osteoma. ILP is a technique in which tumour tissue is destroyed by direct heating using low-power laser light energy delivered by thin (400 microm) optical fibres which are introduced percutaneously into the tumour under image guidance. Pain was evaluated b...

Eales' disease is an idiopathic obliterative retinal vasculopathy that is treated with laser photocoagulation, and/or vitrectomy. In order to determine visual outcomes and regression of retinal neovascularization following scattered peripheral retinal photocoagulation, and/or vitrectomy in cases with Eales' disease, we did a retrospective study of the records of these patients treated in La...

The aim of this study was to investigate the feasibility of using 980 nm diode laser for interstitial laser photocoagulation (ILP) before clinical application in benign thyroid nodule treatment. The bovine livers were cut into blocks to irradiate with 980 nm laser through the lumen of a 20-gauge spinal needle using a fiber optic guide. Laser irradiation was performed with the output power of 2 ...

Introduction: The aim of the present study was to determine burn intensity in retinal laser photocoagulation based on laser parameters; wavelength, power, beam size and pulse duration, using Optical Coherence Tomography (OCT), fundus camera, physical eye model and computer simulation in a clinical study.Materials and Methods: Participants were 10 adult patients between 50-80 years with prolifer...

BACKGROUND Management of peripheral lung tumours may be risky in patients with poor lung function or in the elderly. A new possibility is interstitial laser photocoagulation (ILP) in which tumours are gently coagulated using thin laser fibres placed percutaneously under radiological guidance. This could have a useful palliative role in selected patients, but to be safe the effects on normal lun...

A nonlinear mathematical model was developed and experimentally validated to investigate the effects of changes in optical properties during interstitial laser photocoagulation (ILP). The effects of dynamic optical properties were calculated using the Arrhenius damage model, resulting in a nonlinear optothermal response. This response was experimentally validated by measuring the temperature ri...
