详细说明

To be eligible for enrollment in this study, patients must receive the first injection of Macugen intravitreal in at least one eye for treatment of wet age-related macular degeneration (AMD). The decision to prescribe Macugen will necessarily precede and will be independent of the decision to enroll patient into the study.

If both eyes of a patient receive injection Macugen, only one eye will be included in the study. If both eyes receive first injection Macugen after initiation of the study, only the first treated eye will be included in the analysis. If one eye has already received Macugen when the study starts and the second eye receives injection after the study initiation, the second eye will be included in the analysis.

The study was prematurely discontinued due to delay in meeting pre-defined protocol recruitment milestones on August 30, 2010. There were no safety concerns regarding the study in the decision to terminate the trial.

主要结果指标

结果测量	措施说明	大体时间
Percentage of Participants Showing Stabilization, Improvement or Deterioration of Visual Acuity (VA) 大体时间：Baseline through 12 months or last follow-up visit before study termination	VA was measured using ETDRS (Early Treatment Diabetic Retinopathy Study) chart at 4 meter distance, at 1 meter distance (if participant's VA was poor) or verifying if the participant was able only to count fingers, to perceive hand motion or light. VA was assessed as the number of ETDRS letters correctly read. VA statuses were defined as: Stabilization: loss of less than 15 letters in the best corrected VA (BCVA); Improvement: gain of more than or equal to 15 letters in the BCVA; Deterioration: loss of more than or equal to 15 letters in the BCVA.	Baseline through 12 months or last follow-up visit before study termination
Average Number of Injections to Achieve Stabilization of VA 大体时间：12 months or last follow-up visit before study termination	Stabilization of VA was defined as loss of less than 15 letters in the BCVA. For each participant, number of injections before reaching the first "stabilization in VA" (considered as an event) was counted. For participant having no event, the time to the number of injections to reach an event was unobserved at the number of injections before the last follow up.	12 months or last follow-up visit before study termination
Median Number of Injections to Achieve Stabilization of VA 大体时间：12 months or last follow-up visit before study termination	Stabilization of VA was defined as loss of less than 15 letters in the BCVA. Median number of injections to achieve stabilization of VA was estimated via the Kaplan Meier method. For each participant, number of injections before reaching the first "stabilization in VA" (considered as an event) was counted. For participant having no event, the time to the number of injections to reach an event was unobserved at the number of injections before the last follow up.	12 months or last follow-up visit before study termination

次要结果测量

结果测量	措施说明	大体时间
Percentage of Participants Receiving Macugen Monotherapy Versus Those Receiving a Combination Therapy 大体时间：12 months or last follow-up visit before study termination	Macugen monotherapy: referred to participants receiving Macugen in the study eye during the study that is (i.e.) participants without any concomitant drug treatment or nondrug treatment for the study eye during the study. Combination therapy: referred to participants receiving combination therapy in the study eye (during the study) i.e. participants with any concomitant drug treatment or nondrug treatment for the study eye during the study.	12 months or last follow-up visit before study termination
Percentage of Participants Showing Improvement in Optical Coherence Tomography (OCT) Parameters 大体时间：12 months or last follow-up visit before study termination	OCT, a noninvasive, noncontact, transpupillary imaging technology, was utilized to image retinal structures in vivo with a resolution of 10 to 17 microns. The anatomic layers within the retina, retinal thickness could be measured. Improvement in OCT parameters was defined as a reduction of more than or equal to 100 microns in the central macular thickness (Center subfield).	12 months or last follow-up visit before study termination
Percentage of Participants Showing Improvement in Fundus Fluorescein Angiography (FFA) Parameters 大体时间：12 months or last follow-up visit before study termination	A fluorescein angiogram provides information about the condition of the retina. Improvement in FFA parameters was defined as absence of progression of the lesion or decrease in the size of the lesion and absence of new lesions on FFA i.e. change in lesion size from baseline must be less than or equal to 0 disc area(DA) and no new lesions.	12 months or last follow-up visit before study termination
Percentage of Participants With Early Lesions Showing Stabilization and Improvement of VA 大体时间：12 months or last follow-up visit before study termination	Early lesions were defined by any 2 of the following criteria: occult lesion diagnosed on FFA; baseline VA of more than or equal to 54 ETDRS letters; lesion size of less than 2DA on FFA. Stabilization of VA was defined as loss of less than 15 letters in the BCVA. Improvement in the VA was defined as gain of more than or equal to 15 letters in the BCVA.	12 months or last follow-up visit before study termination
Average Number of Injections to Achieve Stabilization of VA in Participants With Early Lesions 大体时间：12 months or last follow-up visit before study termination	Stabilization of VA was defined as loss of less than 15 letters in the BCVA. For each participant, number of injections before reaching the first "stabilization in VA" (considered as an event) was counted. For participant having no event, the time to the number of injections to reach an event was unobserved at the number of injections before the last follow up.	12 months or last follow-up visit before study termination
Median Number of Injections to Achieve Stabilization of VA in Participants With Early Lesions 大体时间：12 months or last follow-up visit before study termination	Stabilization of VA was defined as loss of less than 15 letters in the BCVA. Median number of injections to achieve stabilization of VA in participants with early lesions was estimated via the Kaplan Meier method. For each participant, number of injections before reaching the first "stabilization in VA" (considered as an event) was counted. For participant having no event, the time to the number of injections to reach an event was unobserved at the number of injections before the last follow up.	12 months or last follow-up visit before study termination
Percentage of Participants With Occult or Minimally Classic and Classic Lesions Showing Stabilization and Improvement in VA 大体时间：12 months or last follow-up visit before study termination	FFA was utilized to characterize the lesions as follows: Classic lesion: more than 50% of the lesion had a well-demarcated area of hyperfluorescence; minimally classic lesion: less than or equal to 50% of lesion had well-demarcated area of hyperfluorescence; occult lesion: lesion with no well demarcated borders. VA statuses were defined as: stabilization: loss of less than 15 letters in the BCVA; improvement: gain of more than or equal to 15 letters in the BCVA.	12 months or last follow-up visit before study termination
Percentage of Participants Who Were Treatment Naive When Started on Macugen Versus Those Previously Treated by Any Other Therapy Except Macugen 大体时间：12 months or last follow-up visit before study termination	Participants were considered treatment naive when started on Macugen and without any previous drug or non drug treatment administered to the study eye. Participants were considered previously treated by any other therapy if received any other drug or non drug treatment to the study eye except Macugen.	12 months or last follow-up visit before study termination
