We operated on nine eyes in eight patients with retinal detachment associated with acute retinal necrosis (ARN) syndrome. The patients were treated with scleral buckling, vitreoretinal surgery, or a combination of these treatments. Vitrectomised eyes underwent combinations of lensectomy, membrane dissection, scleral buckling, air-fluid exchange, endolaser photocoagulation, cryotherapy, and reti...

introduction: implant bed preparation with laser is taken into consideration owing to the increased interest in use of lasers in hard tissue surgery. the purpose of this study is to determine the deviations in the position and inclination between the planned and prepared implant beds with erbium, chromium doped yttrium scandium gallium garnet (er,cr: ysgg) laser using stereolithographic (sla) s...

Severe postoperative cystoid macular edema associated with posterior uveitis, commonly referred to as Irvine-Gass syndrome, may occur after intraocular surgery and result in visual loss. There is little consensus on the efficacy of various topical, peribulbar, retrobulbar, or intravitreal therapeutic options compared to natural history, but patients with this condition are often referred to ret...

Introduction Retinal detachment (RD) surgery is the most common retinal surgery performed. RD can be repaired either by scleral buckling (SB) or pars plana vitrectomy (PPV). Pneumoretinopexy, laser delimitation or observation can be done in selected cases. The decision to perform SB or vitrectomy depends on various factors, including age of the patient, duration and extent of RD, presence of pr...

introduction: the aim of this study was to assess the effect of low-level laser therapy (lllt) on pain, swelling and maximum mouth opening in patients undergoing third molar surgery. methods: a prospective, randomized double-blind study was undertaken on 44 patients at the dental school, ahvaz jundishapur university of medical sciences, in 2015. a low-level laser was randomly applied on one of ...

PURPOSE Retinal injuries that affect the photoreceptors and/or the retinal pigment epithelium (RPE) may result in the leakage of retinal proteins into the systemic circulation. This study was designed to determine whether an immune response is elicited after an acute retinal injury resulting in circulating anti-retinal antibodies in the serum. METHODS Fifty laser burns of different grades (mi...

PURPOSE To investigate whether the detection of apoptosing retinal cells (DARC) could detect cells undergoing apoptosis in a laser model of retinal damage. METHODS Laser lesions were placed, with the use of a frequency-doubled Nd:YAG laser, on the retina in 34 eyes of anesthetized Dark Agouti rats. Lesion size and laser-induced retinal elevation were analyzed using in vivo reflectance imaging...

Introduction: Radical laryngeal surgeries for extensive laryngeal and hypopharyngeal tumors often require a permanent tracheostomy, which has an immense impact on the quality of life of patients. A minimally invasive technique such as transoral laser microresection (TLM) followed by radiotherapy can preserve the functions of the voice and swallowing. The aim of this study is to evaluate the ro...
