PURPOSE To map the colour contrast sensitivity (CCS) and possible elevations of colour contrast thresholds in Swedish ophthalmologists operating argon lasers. MATERIAL AND METHODS CCS was measured by a computer and colour monitor system developed by Arden and co-workers. CCS of 58 Swedish ophthalmologists, all users of argon laser, was compared to 26 age-matched controls. The ophthalmologists...

OBJECTIVE To document the frequency of retinal detachment and other complications associated with Nd:Yag laser capsulotomy. METHODS This prospective study was conducted among patients who underwent Nd:Yag laser capsulotomy in a tertiary care hospital in a period of one year. All patients had a thorough slit lamp biomicroscopic examination before and after the capsulotomy. A follow-up was done...

uncontrolled hypertension is well- known to give rise to systemic complications involving multiple central organs. artherosclerosis leads to damage of the retinal vessels wall, contributing to venous stasis, thrombosis and finally, occlusion. retinal vein occlusions compromise vision through development of ischaemic maculopathy, macular oedema, and rubeotic glaucoma. laser photocoagulation rema...

Aims—To study the eVects of segmental scleral buckling and encircling procedures on tissue circulation in the human optic nerve head (ONH) and choroid and retina. Methods—Using the laser speckle method, the normalised blur (NB) value, a quantitative index of tissue blood velocity, was measured every 0.125 seconds and averaged over three pulses in the optic nerve head (NBONH) and choroid and ret...

purpose: to study the effects of adding intravitreal bevacizumab (avastin) to conventional laser treatment on regression of retinal neovascularization in threshold rop. methods: intravitreal injection of bevacizumab (1.25 mg) in one eye of each of three newborns with threshold rop was performed in addition to laser treatment. the other eye of each patient was treated with laser alone. changes i...

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...

Ophthalmology was the first medical specialty to adopt lasers right after their invention more than 50 years ago, and they gradually revolutionized ocular imaging, diagnostics, therapy, and surgery. Challenging precision, safety, and selectivity requirements for ocular therapeutic and surgical procedures keep advancing the laser technologies, which in turn continue enabling novel applications f...

Marfan syndrome (MFS) is a genetic disorder which is inherited by autosomal dominant traits. In MFS, lens displacement and cardiovascular involvement are important causes of morbidity and mortality in the clinical course of the disease. In this case study, the ocular involvement in a family with severe penetration of MFS is reported. Twelve members of a family (father, two daughters, three sons...

background postoperative pain is a common complication that can lead to serious morbidities and delayed recovery. objectives the aim of this study was to investigate the effect of low-level laser therapy on acute pain after tibial fracture surgery. patients and methods in this randomized clinical trial, 54 patients who were candidate for tibial fracture surgery were allocated randomly to two gr...
