PHASE1
Brief Summary
The purpose of this study is to determine whether ranibizumab will be effective in reducing if not eliminating the macular edema associated with the disease, central retinal vein occlusion (CRVO).
Detailed Description
Retinal Venous Occlusive disease is the second only to diabetic retinopathy as a major cause of blindness associated with retinal vascular disease. Macular edema is a major cause of vision loss in pat...
Eligibility Criteria
Inclusion
- Ability to provide written informed consent and comply with study assessments for the full duration of the study
- Age \> 18 years
- Clinical evidence of perfused central retinal vein occlusion. A central retinal vein occlusion (CRVO) is defined as an eye that has retinal hemorrhages and a dilated retinal venous system in all 4 quadrants. Other evidence of a CRVO may include telangiectatic capillary bed and collateral vessels at the optic nerve head.
- Central macular edema present on clinical examination and OCT testing with a central point thickness \> 250 microns
- Visual acuity score greater than or equal to 19 letters (20/400) and less than or equal to 73 letters (20/40) by the ETDRS visual acuity protocol.
- Media clarity, pupillary dilation and patient cooperation sufficient to allow OCT testing and retinal photography
Exclusion
- Pregnancy (positive pregnancy test) or known to be pregnant, also premenopausal women not using adequate contraception.
- Participation in another simultaneous ocular investigation or trial
- Patient with uncontrolled hypertension
- Patient has a condition that, in the opinion of the investigator would preclude participation in the study (i.e. chronic alcoholism, drug abuse)
- Patient has significant diabetic retinopathy (greater than moderate NPDR) or macular edema associated with diabetic retinopathy
- Exam or OCT reveals evidence of vitreoretinal interface abnormality that may be contributing to the macular edema
- Eye that in the investigator has no chance of improvement in visual acuity following resolution of macular edema (i.e subretinal fibrosis or geographic atrophy)
- Presence of another ocular condition that may affect the visual acuity or macular edema during the course of the study (i.e AMD, uveitis, Irvine-Gas)
- Evidence of neovascularization of the iris or retina (presence of ischemic CRVO)
- Presence of substantial cataract, one that might decrease the vision by 3 or more lines of vision at sometime during the study.
- History of Grid/Focal laser or Panretinal laser in the study eye
- History of vitreous surgery in the study eye
- History of use of intravitreal, peribulbar, or retrobulbar steroids within six months of the study.
- History of Cataract Surgery within 6 months of enrollment.
- History of YAG capsulotomy within 2 months of the surgery.
- Visual acuity \<20/400 in the fellow eye
- Uncontrolled Glaucoma, pressure \>30 despite treatment with glaucoma medications.
