Filter by:The purpose of this research study is to evaluate an investigational system that may allow doctors to show images of the different parts inside the eye that show greater detail than current equipment can produce.
Age-related macular degeneration (ARMD) affects older Americans and can lead to irreversible blindness. Although the cause if ARMD is unclear, it appears to be a condition that is affected by both genetic and environmental influences. The purpose of this study is to examine an Amish community to investigate genetic factors in the development of ARMD. Study participants will be 1,000 members, ages 50 and older, of the Old Order Amish community in Lancaster and Franklin counties in Pennsylvania. Each will undergo a 30-minute dilated eye exam during which an ophthalmologist or optometrist will take digital images of the macula and optic disc. Depending on the results of their eye exam, participants may be asked to give a blood sample as well. They will also complete a brief questionnaire about personal exposure related to occupation, sunlight and smoking.
Ranibizumab is a humanised recombinant monoclonal antibody fragment targeted against human vascular endothelial growth factor A. This study will assess the safety and efficacy of ranibizumab administered on an as-needed dosing regimen in patients with subfoveal choroidal neovascularization (CNV) secondary to age-related macular degeneration (AMD).
The purpose of this study is to evaluate and conduct an exploratory comparison of the efficacy and safety of indocyanine green angiography (ICGA) guided photodynamic therapy (PDT) and fluorescein angiography (FA) guided PDT for exudative age-related macular degeneration (AMD) accompanied with polypoidal choroidal vasculopathy (PCV).
Standard perimetry provides information on topographical retinal sensitivity to light stimuli, however the said locus is not necessarily the preferred locus for fixation. Standard perimetry could also be used as a way for macular scotoma mapping, indirectly showing the fixation locus. Topographic acuity at the preferred retinal locus can be determined if correlation between loci with high sensitivity, eccentric fixation loci and potential visual acuity measurements are correlated. PURPOSE OF THE STUDY: Determination of visual acuity at preferred retinal locus in Low Vision patients with ARMD using eye standard automated and computerized perimetry methods.
To evaluate the efficacy, based on the best-corrected visual acuity (using the ETDRS chart), of a 0.3 mg/eye pegaptanib sodium intravitreous injection given every 6 weeks for 54 weeks in patients with exudative age-related macular degeneration and evidence of recent onset, subfoveal and/or juxtafoveal choroidal neovascularization.
The purpose of this study is to compare the ability of different doses of pegaptanib sodium to safely and effectively minimize fluid leakage within the eye, thereby stabilizing or impriving vision in patients with wet AMD when compared to placebo injections.
This study examines the effect of intravitreally administered VEGF Trap in patients with wet AMD. The purpose of this trial is to assess the ocular and systemic safety and tolerability of repeated intravitreal doses of VEGF Trap in patients with subfoveal choroidal neovascularization (CNV) due to AMD.
The purpose of this trial is to assess the ocular and systemic safety and tolerability of a single intravitreal injection of VEGF Trap in patients with subfoveal choroidal neovascularization (CNV) due to AMD.
This study will evaluate the safety and efficacy of the intravitreal implant of dexamethasone for the treatment of macular edema associated with branch retinal vein occlusion.
