Brief Summary
This research is being done to look at the effects of an experimental drug called pegaptanib (also called Macugen) for the treatment of swelling in the retina (the light sensitive tissue in the back of the eye) that can occur after cataract surgery. Swelling in the retina can lead to blurry vision. The only treatment available for this condition is eye drops that decrease swelling in the back of the eye, but eye drops may not decrease the swelling in everyone. We want to see if pegaptanib can decrease swelling in the retina and improve vision in patients with swelling after cataract surgery.

Outcome Measures
Primary Outcomes (3)
Proportion of subjects improving >/= 15 letters (3 lines) of best-corrected distance visual acuity at 18 weeks after initiation of pegaptanib. Distribution of visual acuity changes at 18 weeks after initiation of pegaptanib
18 weeks after enrollment
Distribution of absolute levels of distance visual acuity at 18 weeks after initiation of pegaptanib
18 weeks after enrollment
Analysis of time to 15 letter improvement of best-corrected distance visual acuity through 18 weeks after initiation of pegaptanib using a 2-state stochastic model to account for events and recoveries from events
18 weeks after enrollment
Secondary Outcomes (3)
Analysis of decrease in retinal thickness by OCT at 18 weeks after initiation of pegaptanib
18 weeks after enrollment
Analysis of improvement of fluorescein leakage seen on fluorescein angiography at 18 weeks after initiation of pegaptanib
18 weeks after enrollment
Additional changes 12 weeks after discontinuation of pegaptanib (6 months after study entry)
6 months after enrollment

PLACEBO COMPARATORInterventions
0.3 mg/0.1 ml intravitreal injection, every 6 weeks, up to a total of 3 injections
Eligibility Criteria
You may qualify if:
- Adults (ages 18 years or older)
- Best corrected visual acuity \< 20/40 but no worse than 20/800 in the study eye
- Best corrected visual acuity better than or equal to 20/200 in the fellow eye
- Post-surgical CME in the study eye as documented on OCT (central subfield \>/= 250 microns)
- Women of child-bearing potential who are interested in participating in this study will use two effective forms of contraception prior to initiation of pegaptanib and then throughout the remainder of the study. For women of childbearing potential, results from a urine pregnancy test will be obtained prior to each injection with pegaptanib. Urine samples will be disposed of after the test is performed.
- Initiation of pegaptanib or sham injections may begin following at least 12 weeks of topical therapy for CME after cataract surgery or the other eye,if the best-corrected visual acuity has not improved by at least 5 letters and if the center point thickening on OCT has not improved by at least 20%. Patients who have been on topical ketorolac for greater than 12 weeks are still eligible for this study.
You may not qualify if:
- History of intravitreal steroid (triamcinolone) injection into the study eye or fellow eye within 4 months prior to cataract surgery
- CME due to other etiologies such as vein occlusion and diabetes.
- Retinal diseases that preclude evaluation of the macula for edema (e.g., macular hole).
