Newly diagnosed exudative age-related macular degeneration treated with pegaptanib sodium monotherapy in US community-based practices: medical chart review study

<p>Abstract</p> <p>Background</p> <p>Studies have shown that early detection and treatment of neovascular age-related macular degeneration (NV-AMD) can delay vision loss and blindness. The objective of this study was to evaluate the efficacy/safety of intravitreal pegaptanib sodium monotherapy in treatment-naïve subjects with newly diagnosed NV-AMD and to gain insight into characteristics of lesions treated in community-based practices.</p> <p>Methods</p> <p>From seven private US practices, charts were retrospectively reviewed on 73 subjects with previously untreated subfoveal choroidal NV-AMD treated with their first dose of pegaptanib monotherapy on/after 4/1/2005 through 6/5/2006, receiving ≥4 treatments at 6-week intervals over 21 weeks. Primary endpoint: mean visual acuity (VA) change from baseline to month 6.</p> <p>Results</p> <p>75% of lesions were occult, and 82% were subfoveal. From baseline to month 6, mean VA change was -0.68 lines; 58% and 16% gained ≥0 and ≥3 lines of VA, and 70% were responders (<3 lines lost). In 35 subjects with early disease, 80% were responders with a mean gain of 0.46 lines.</p> <p>Conclusion</p> <p>Pegaptanib is effective in real-world patients with treatment-naïve NV-AMD in uncontrolled community-based retina practices.</p

Verteporfin therapy in occult with no classic CNV due to AMD: results of the Photodynamic Therapy in Occult-Only Lesions study

PURPOSE: To provide further information on verteporfin photodynamic therapy in occult with no classic choroidal neovascularization (CNV) secondary to age-related macular degeneration (AMD). METHODS: Verteporfin therapy was administered at baseline and then at months 3, 6, and 9, if fluorescein leakage from CNV was evident on angiography. RESULTS: Of 202 patients enrolled, 184 completed 12 months. Each patient was treated in one eye only. All study eyes received verteporfin therapy at baseline, with a progressive decrease in the number treated at subsequent visits (mean 2.5 treatments during 12 months). The mean change in visual acuity letter score from baseline to month 12 was -11.9. At month 12, 164 eyes (82.4%) had lost 5-letter increase, and 7 (3.5%) had >15-letter improvement. The percentage of eyes with fluorescein leakage from CNV decreased from 75.5% at month 3 to 25.1% at month 12. Adverse events were documented for 54% patients. Few patients had treatment-associated adverse events (7%). Acute severe visual acuity decrease occurred in two eyes (1%), one of which had visual acuity that returned to baseline by the next follow-up visit. CONCLUSIONS: This study provides additional evidence that over 12 months, verteporfin is generally well tolerated and maintains or improves visual acuity in over one-third of eyes containing occult-only CNV. Verteporfin also improved anatomical outcomes by reducing leakage from CNV in at least two-thirds of eyes
