Low-intensity/high-density subthreshold microPulse diode laser for chronic central serous chorioretinopathy
ABSTRACT PURPOSE: To evaluate the visual outcomes and macular thickness change in patients with symptomatic chronic central serous chorioretinopathy after treatment with a subthreshold MicroPulse diode laser. METHODS: In this retrospective, interventional case series, 10 patients were treated with the subthreshold 810-nm diode MicroPulse laser. Selected patients had symptomatic disease that may or may not… Read More
Efficacy of subthreshold micropulse laser in the treatment of diabetic macular edema is influenced by pre-treatment central foveal thickness
ABSTRACT PURPOSE: To determine if the severity of diabetic macular edema influences the effectiveness of subthreshold micropulse (STMP) laser treatment. METHODS: A total of 63 eyes of 58 patients with diabetic macular edema were divided into two groups based on their initial central foveal thickness (CFT). Group 1 had CFT ≤400 μm, group 2 had CFT… Read More
Sequential in-office vitreous aspirates demonstrate vitreous matrix metalloproteinase 9 levels correlate with the amount of subretinal fluid in eyes with wet age-related macular degeneration
ABSTRACT PURPOSE: To evaluate levels of 37 native pathway proteins of the vitreous proteome from a subset of wet age-related macular degeneration (AMD) patients with and without subretinal fluid (SRF). METHODS: A total of 62 consecutive samples were aspirated from 12 patients with AMD, six who had SRF at baseline, and six who did not… Read More
A prospective study of in-office diagnostic vitreous sampling in patients with vitreoretinal pathology
ABSTRACT PURPOSE: To evaluate the safety and efficacy of in-office vitreous sampling (50-100 microL). METHODS: A prospective, consecutive case series of 578 diagnostic vitreous sample attempts performed between February 23, 2007 and September 31, 2008. A standardized technique of vitreous sampling followed by intravitreal injection of therapeutic medication was performed. All subjects were followed for… Read More
Activated VEGF receptor shed into the vitreous in eyes with wet AMD: a new class of biomarkers in the vitreous with potential for predicting the treatment timing and monitoring response
ABSTRACT OBJECTIVE: To examine whether phosphorylated vascular endothelial growth factor (VEGF) receptors shed into the vitreous reflect the ongoing retinal and choroidal signal pathway activity in wet age-related macular degeneration (AMD). METHODS: Vitreous samples obtained immediately prior to anti-VEGF injection from 11 patients with choroidal neovascularization were analyzed using reverse-phase microarrays. Two patients had samples… Read More
Intraocular tamponade duration and success of macular hole surgery
ABSTRACT PURPOSE: The authors compare the success of macular hole surgery with a short duration tamponade using 5% perfluoropropane (C3F8), intermediate duration tamponade using 10% C3F8, or a long duration tamponade using 16% C3F8 in a prospective consecutive clinical trial at two institutions. METHODS: Vitrectomy and fluid-gas exchange was performed in 29 eyes treated with… Read More
Reoperation after failed macular hole surgery.
ABSTRACT PURPOSE: The authors determined the anatomic and visual success rates of vitrectomy in patients who have failed previous macular hole surgery. METHODS: Standardized Early Treatment Diabetic Retinopathy Study (ETDRS)-style best-corrected visual acuity was measured in each patient pre- and postoperatively. Surgery was performed at two centers using a standardized protocol, as previously reported, using… Read More
Vitrectomy, fluid-gas exchange and transforming growth factor–beta-2 for the treatment of traumatic macular holes.
ABSTRACT PURPOSE: To evaluate whether vitreous surgery is successful in closing full-thickness traumatic macular holes and whether there is subsequent improvement in visual acuity. METHODS: Twelve eyes from 12 consecutive patients with traumatic macular holes underwent vitrectomy, fluid-gas exchange and instillation of bovine or recombinant transforming growth factor (TGF)-beta-2. Three of four eyes underwent repeat… Read More
