PURPOSE To present the state-of-the-art of subthreshold diode laser micropulse photocoagulation (SDM) as invisible retinal phototherapy for diabetic macular edema (DME). METHOD To review the role and evolution of retinal laser treatment for DME. RESULTS Thermal laser retinal photocoagulation has been the cornerstone of treatment for diabetic macular edema for over four decades. Throughout, ...

We investigate the relationship between the laser beam at the retina (spot size) and the extent of retinal injury from single ultrashort laser pulses. From previous studies it is believed that the retinal effect of single 3-ps laser pulses should vary in extent and location, depending on the occurrence of laser-induced breakdown (LIB) at the site of laser delivery. Single 3-ps pulses of 580-nm ...

Retinopathy of Prematurity Transscleral Retinal Photocoagulation (TSRPC) The 810 nm diode laser wavelength makes lens-sparing transscleral coagulation of the retina possible, and to evaluate the efficacy and safety of transscleral diode laser coagulation for threshold ROP, the authors performed a controlled clinical study. Forty eyes of 20 preterm infants (gestational age 24-29 weeks, mean 26.8...

OBJECTIVE To evaluate costs and treatment benefits of rhegmatogenous retinal detachment (RD) repair. DESIGN A Markov model of cost-effectiveness and utility. PARTICIPANTS There were no participants. METHODS Published clinical trials (index studies) of pneumatic retinopexy (PR), scleral buckling (SB), pars plana vitrectomy (PPV), and laser prophylaxis were used to quantitate surgical manag...

BACKGROUND To evaluate wide-field laser ophthalmoscopy (Optomap 200Tx) for screening retinal lesions before myopic refractive surgery. METHODS Seventy-eight eyes of 78 consecutive refractive surgery candidates were included in this study. All subjects underwent Optomap 200Tx, mydriatic slit-lamp lens examination and the Goldmann three-mirror contact lens examination, which was considered as t...

RATIONALE AND OBJECTIVE The major objective of treatment in glaucomatous disease is the decrease of intraocular pressure while maintaining the patient's vision and quality of life. Despite therapeutic possibilities, some cases of glaucoma remain refractory to treatment with the maintenance of elevated intraocular pressure and further progression of the disease.Artificial drainage systems, Ahmed...

To compare refractive changes following 23-gauge (G) vitrectomy with or without gas tamponade in pseudophakic eyes. This retrospective study included patients neodymium: yttrium-aluminum-garnet (Nd: YAG) laser capsulotomy, who underwent 23 G pars plana (PPV) between February 2015 and March 2019. Indications for surgery included; rhegmatogenous retinal detachment Group 1 epiretinal membrane vitr...

AIM To report the clinical findings, management, and outcomes in eyes undergoing surgery for regressed retinopathy of prematurity (ROP) with vitreoretinal complications. METHOD Retrospective review of 40 eyes of 32 patients with regressed ROP who presented between 1989 and 2001 at two UK referral centres. RESULTS Of 29 eyes presenting with rhegmatogenous retinal detachment (RRD), 15 initial...

PURPOSE To evaluate the outcome after buckle removal in a consecutive series of treated detachments. METHODS Segmental and/or encircling buckles were removed in 46 consecutive patients operated upon for rhegmatogenous retinal detachment, showing buckle extrusion, recurrent pain, and diplopia. Patients underwent a preoperative retinal examination, and a six- months postoperative follow-up. R...

PURPOSE To develop an inducible mouse model of glaucoma. METHODS An obstruction of aqueous humor outflow in adult C57BL6/J mice was induced by combined injection of indocyanine green (ICG) dye into the anterior chamber and diode laser treatment. To evaluate intraocular pressure (IOP), tonometry was performed with a modified Goldmann tonometer. The function of the retina was evaluated with ele...
