RESUMEN
BACKGROUND AND OBJECTIVE: Verteporfin photodynamic therapy (vPDT) plays a role in the treatment of chorioretinal conditions. The purpose of this study was to compare vPDT outcomes between cataractous and pseudophakic eyes. PATIENTS AND METHODS: In this prospective study of consecutive patients with choroidal neovascularization (CNV) secondary to neovascular age-related macular degeneration (nAMD) treated with vPDT, cataract and pseudophakic eyes were compared for number and timing of vPDT treatments, duration of follow-up, angiographic features, and changes in best-corrected visual acuity (BCVA). RESULTS: Overall, 103 eyes (n = 95) were included in the final analysis; 44 eyes in the cataract group and 59 eyes in the pseudophakic group. No significant difference in change in BCVA (P = .19) or leakage-free CNV lesions (P = .58) was found between the groups. CONCLUSIONS: In this study of vPDT for nAMD, there was no significant difference between eyes with cataract and pseudophakic eyes. It seems that cataract does not clinically alter the effect of vPDT.

PURPOSE: To evaluate the visual outcome of patients with myopic subfoveal choroidal neovascularization (CNV) given photodynamic therapy (PDT) in a clinical setting, and to identify potential relation between the visual outcome and the age at treatment. DESIGN: Interventional case series. METHODS: Retrospective comparative study. SETTING: Outpatient ophthalmology clinic. PATIENTS: Twenty-nine consecutive patients (30 eyes) with subfoveal CNV caused by pathologic myopia who were treated with verteporfin PDT from January 2000 to May 2003. INTERVENTION: All the patients received verteporfin PDT and were followed clinically and with fluorescein angiography (FA). Review of the medical records and angiograms was performed. Patients were divided into two groups by age, using the median age (60 years) as the cutoff. MAIN OUTCOME MEASURES: Visual acuity (VA) at the end of follow-up in the older-patient group compared with the younger-patient group. RESULTS: The mean age was 63.1 years. Mean follow-up was 11.5 months. Patients received a mean of 3.48 treatments. Mean VA improved in the younger group from 0.63 to 0.39 logMAR (P = .02, paired t test) and deteriorated in the older group from 0.71 to 0.99 logMAR (P = .03, paired t test). In the whole cohort, 33% of eyes lost 3 or more lines of Snellen best-corrected VA; in the older age group, 50% of eyes lost 3 or more lines, whereas in the younger age group, only 8% of eyes did so (P = .024, Fisher's exact test). CONCLUSIONS: In our consecutive case series, visual prognosis of myopic CNV after PDT was found to be influenced by age at treatment.
