After photocoagulation of the rabbit retina wound healing occurs with a marked increase in mitoses not only in choroid, pigment epithelium, and retina, where mainly Midler cells are proliferating, but also in the cortical vitreous cells, the hyalocytes. The rate of mitosis in the hyalocytes ivas investigated by administration of systemic colchicine. The rate of mitosis is highest around the thi...

Purpose: To compare the histhologic changes in the retina and chowid, between the continuous and pulsed-wave photocoagulation by diode laser in pigmented rabbits. The r6petitivepulse photocoagulation could prove to be a promising technique for several pathologies in the ocular fundus. Methods: Continuous and pulsed diode-laser transpupillary photocoagulation~ was performed in the eyes of pigmen...

OBJECTIVE To study the incidence and risk factors predisposing to retinopathy of prematurity (ROP) and to assess the outcome after laser photocoagulation. DESIGN Prospective cohort observational study. SETTING Infants admitted to a neonatal intensive care unit of a referral hospital between 2000-2006 and followed up till the age of 3 years. METHODS Preterm infants with birthweight<1500 g ...

PURPOSE The effectiveness and limitations of indocyanine green (ICG) enhanced diode laser photocoagulation in treating subfoveal choroidal neovascularization (CNV) associated with age-related macular degeneration (AMD) were investigated retrospectively. METHODS Thirty-eight eyes of 37 patients with subfoveal CNV received ICG enhanced diode laser (wavelength, 805 nm) photocoagulation in our pr...

BACKGROUND Idiopathic juxtafoveolar retinal telangiectasia (IJRT) type 1 represents an uncommon cause of congenital unilateral visual loss and it typically affects males. Decrease in visual acuity is caused by serous and lipid exudation into the fovea with cystoid macular edema. In some cases, spontaneous resolution may be observed, but when there is a progressive loss of visual acuity, laser p...

PURPOSE To evaluate the clinical features of Type 1 idiopathic macular telangiectasia (IMT) followed up for 2 years. METHODS Forty-nine patients with unilateral Type 1 IMT were examined. Thirty-one IMT eyes were treated with direct laser photocoagulation and/or intravitreal bevacizumab; the remaining 18 eyes, with good vision or slight macular edema, were untreated. Changes in best-corrected ...

OBJECTIVE Retinopathy of prematurity (ROP) is a leading cause of adverse visual outcomes in premature infants. Both laser photocoagulation and cryotherapy have been demonstrated in clinical trials to be efficacious in reducing the incidence of visual loss occurring secondary to threshold ROP. Visual data recently have become available concerning the long-term clinical efficacy of both treatment...

BACKGROUND The dilation of veins and tortuosity of arteries that occur in retinopathy of prematurity (ROP) are improved by therapy, and thus posttherapy changes in ocular circulation are also conceivable. We report a case of ROP in which we were able to measure the ocular circulation before and after photocoagulation therapy, using a laser speckle flowgraphy (LSFG) system that is modified for n...

The aim of this study is to analyse the role of the prophylactic 360 degree laser photocoagulation on vitrectomies for dropped nucleus, and to examine whether it is useful or harmful for the development of retinal detachment by evaluating a retrospective case series. The patients who performed pars plana vitrectomy (PPV) due to the development of dropped nucleus after phacoemulsification betwee...
