Triamcinolone Acetonide Plus Laser Therapy to Treat Age-Related Macular Degeneration

INCLUSION CRITERIA: To be eligible for the study, participants must fulfill all of the following criteria: Understand and sign the IRB-approved informed consent document for the study. Age greater than or equal to 50 years. In the study eye, diagnosis of AMD defined by the presence of drusen larger than 63 micro m. In the study eye, participant has had less than three prior pegaptanib sodium (Macugen (Trademark)) injections, without injection-related complications, (such as endophthalmitis, vitreal hemorrhage, or an elevation of IOP greater than or equal to 10 mmHg compared to baseline), the participant's study eye vision is between 20/40 and 20/125, and the last pegaptanib sodium injection occurred greater than 6 weeks prior to randomization. In the study eye, the presence of choroidal neovascularization under the fovea determined by the site Investigator and defined as any one of the following fluorescein angiographic (FA) features: Early stippled hyperfluorescence of flat retinal pigment epithelium and little or mild leakage in the late frames of the fluorescein (occult). Irregular elevation of the retinal pigment epithelium that does not exhibit discrete or bright hyperfluorescence in the early transit phase of the angiogram. Stippled hyperfluorescence may be present. Late frames may show persistent fluorescein staining or leakage within a sensory retinal detachment overlying this area (occult). Late-phase leakage of undetermined source with leakage at the level of the retinal pigment epithelium in the late-phase frames of the angiogram in which the source of the late leakage cannot be determined from earlier-phase frames of the angiogram (occult). A well-demarcated area of bright hyperfluorescence in the early phase of the angiogram with leakage through the mid- and late-phase frames which obscures the boundaries of the area (classic). For all CNV lesions considered to have occult CNV with no classic CNV, one of the following criteria must be met: A documented loss of visual acuity (5 or more letters of best-corrected visual acuity if both measurements are made using an ETDRS chart or, a doubling of the visual angle if Snellen acuities are available from either an outside referral center or within the participating center (e.g., 20/80 to 20/160 - a doubling of the visual angle is required because of the measurement variability of Snellen acuities)). OR Documented fluorescein angiographic evidence of a greater than or equal to 10% increase in the lesion greatest linear dimension over the 3 months prior to enrollment. OR Documented blood associated with CNV. The greatest linear dimension of the entire lesion (classic CNV, occult CNV and any features that could obscure the identification of classic or occult CNV) has to be less than or equal to 5400 micro m in greatest linear dimension on the retina as measured by the treating ophthalmologist. Visual acuity of 20/40 - 20/200 (73-34 letter score) as measured on an ETDRS chart. Retinal photographs and angiography of sufficient quality, allowing assessment of the macular area according to standard clinical practice, can be obtained. Women of childbearing potential must not be pregnant or lactating, must have a negative pregnancy test at screening and must be practicing an adequate method of birth control. Acceptable methods of birth control include intrauterine device (IUD); oral, dermal (patch), implanted or injected contraceptives; tubal ligation; and barrier methods with spermicide. Willingness to comply with the protocol. EXCLUSION CRITERIA: Participants meeting any of the following criteria will be excluded from the study: Choroidal neovascularization, in the study eye, associated with other ocular diseases such as pathologic myopia, ocular histoplasmosis or posterior uveitis, etc. Presence of geographic atrophy under the fovea in the study eye. Evidence of retinal angiomatous proliferation as suspected by the presence of intraretinal hemorrhage, intraretinal leakage, adjoining serous PED or the presence of a connecting retinal vessel. The presence of a chorio-retinal anastomosis. Decreased vision, in the study eye, due to retinal disease not attributable to CNV, such as nonexudative forms of AMD, geographic atrophy, inherited retinal dystrophy, uveitis or epiretinal membrane. Participants who have any additional ocular diseases that have irreversibly compromised or, during follow-up, could likely compromise the VA of the study eye including amblyopia, anterior ischemic optic neuropathy, clinically significant diabetic macular edema, severe non-proliferative diabetic retinopathy, or proliferative diabetic retinopathy. Decreased vision, in the study eye, due to significant media opacity such as corneal disease or cataract, or opacity precluding photography of the retina; a tear (rip) of the RPE; a vitelliform-like lesion of the outer retina (e.g., as in pattern dystrophies or basal laminar drusen), idiopathic parafoveal telangiectasis, or central serous retinopathy. Presence of fibrosis, hemorrhage, pigment epithelial detachments and other hypofluorescent lesions obscuring greater than 50% of the CNV lesion. History of other antiangiogenic treatment or treatment for CNV (not including photodynamic therapy and pegaptanib sodium injections) in the study eye with transpupillary thermotherapy or other local treatment (such as submacular surgery). Previous laser photocoagulation therapy is acceptable, provided it was not subfoveal. History of photodynamic therapy (PDT) within 1 year of enrollment. Current exam evidence of ocular toxoplasmosis; pseudoexfoliation; external ocular infection, including conjunctivitis; chalazion; significant blepharitis; or aphakia in the study eye (pseudophakic participants are eligible). History of ocular hypertension if intraocular pressure (IOP) is greater than or equal to 25 mm Hg, the participant is on Cosopt with one or more other topical glaucoma medications or is on greater than 2 topical glaucoma medications, not including Cosopt; the most recent visual field, performed within the last 12 months, is abnormal and not attributable to the participant's macular disease; and the optic disc appears glaucomatous. Intraocular surgery (including lens replacement surgery) within 6 weeks prior to randomization. Recent history of (within the last 6 months), or current acute ocular or periocular infection (including any history of ocular herpes zoster or simplex). History of prior treatment with intravitreal corticosteroids. History of peribulbar steroid injection within 6 months prior to randomization. History of oral steroid use at any time during the 30 days prior to randomization. History of untoward complications from corticosteroid therapy, including elevated intraocular pressure in response to topical or periocular corticosteroids that required IOP-lowering treatment. Known hypersensitivity/allergy to verteporfin, porfimer sodium, or other porphyrins, porphyria or other porphyrin sensitivity, or hypersensitivity to sunlight or bright artificial light. Participation in any other clinical study or are receiving, or have received any experimental systemic treatment for AMD (e.g.: retinoic acid, thalidomide) or any other investigational new drug within 12 weeks prior to the start of study treatment. Medical problems that make consistent follow-up over the treatment period unlikely (e.g. stroke, severe MI, end stage malignancy), any contraindications to performing the necessary diagnostic studies (i.e., known allergy to fluorescein dyes, etc.), or in general a poor medical risk because of other systemic diseases or active uncontrolled infections. History of moderate to severe abnormal liver function, unless documented evidence of normal liver enzymes is provided.
