AIM To examine the clinical efficacy of contact transscleral retinal photocoagulation with a diode laser. METHODS Transscleral retinal photocoagulation was performed on 36 eyes. The conditions treated included peripheral retinal breaks associated with retinal detachments (30 eyes) and giant retinal tears (six eyes). Of the 30 eyes with retinal detachments, 28 underwent transscleral photocoagu...

PURPOSE To identify any possible relation between glycaemic control and previous laser photocoagulation for diabetic retinopathy. METHODS Seventy-two patients with diabetes were included in the study and were separated into 2 groups according to previous treatment (group A) or not (group B) with argon laser photocoagulation. Glycaemic control was estimated by measuring blood levels of HbA1c i...

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...

It has been well established that laser treatment for type 1 prethreshold retinopathy of prematurity is effective in approximately 90 percent of treated eyes, avoiding retinal detachment.1 Transpupillary laser therapy is certainly the standard; however, there are circumstances in which transpupillary treatment may be difficult or impossible to perform thus allowing progression of retinopathy of...

Glaucoma is one of the major causes of blindness in the world. Elevated intraocular pressure is a major risk factor. Laser photocoagulation induced ocular hypertension is one of the well established animal models. This video demonstrates how to induce ocular hypertension by Argon laser photocoagulation in rat.

CASE REPORT A 55 year old woman presented with retinal vasculitis, multiple aneurysms, macular exudation and widespread retinal nonperfusion and was diagnosed with IRVAN. She was treated with panretinal laser photocoagulation. After 3 years of follow up visual acuity remains stable and there are no complications due to ischaemic sequelae. DISCUSSION IRVAN syndrome with neovascularisation can ...

PURPOSE To perform acridine orange digital fluorography on rats after scatter photocoagulation to investigate alterations of retinal microcirculation at the capillary level, the authors used leukocyte dynamics as a parameter. METHODS Twenty-five pigmented rats (Long-Evans) were studied. Argon laser photocoagulation, extending 6 disc diameters from the optic disc, was delivered to one half of ...

Since its discovery in the 1940s, retinal photocoagulation has evolved immensely. Although the first photocoagulators utilised incandescent light, it was the invention of laser that instigated the widespread use of photocoagulation for treatment of retinal diseases. Laser permits choice of electromagnetic wavelength in addition to temporal delivery methods such as continuous and micropulse mode...
