RESUMO
AIM: To determine the one-year outcomes of resveratrol oral supplement in patients suffering from wet age-related macular degeneration (AMD). METHODS: Fifty naïve and previously untreated patients suffering from wet AMD, were randomly assigned in two subgroups of 25 patients each. All the participants were treated with 3 monthly intravitreal injections of 2.0 mg aflibercept (IAIs) followed by injections "according to need", while in one group the patients also received daily two tablets of resveratrol oral supplement. Prior to treatment initiation, a complete ophthalmological examination, including best corrected visual acuity (BCVA) and contrast sensitivity evaluation, optical coherence tomography (OCT) scans, fundus autofluorescence (FAF), fluorescein angiography, indocyanine green angiography, and OCT angiography (OCTA), was performed to every participant, while all of them completed the Hospital Anxiety and Depression Scale (HADS) questionnaire, in order to assess their quality of life (QoL) status. The patients were assessed monthly for 1y with FAF, and OCT or OCTA; the main endpoints were the number IAIs, the changes in BCVA, in contrast sensitivity, and in patients' QoL status. RESULTS: No significant differences were present between the groups regarding the baseline demographic and clinical data. Over the 12-month period, a similar number of IAIs was applied in both groups (4.52±1.00 vs 4.28±0.90, P=0.38), while the rest of the clinical data also did not differ significantly after the completion of the study period. However, for HADS Depression (11.88±2.51 vs 8.28±1.54, P<0.001) and HADS Anxiety (11.92±2.52 vs 7.76±1.51, P<0.001) questionnaires values, the score was significantly better in patients who received resveratrol supplements. Moreover, a statistically significant difference was detected in the mean change from baseline values of contrast sensitivity (0.17±0.19 vs 0.35±0.24, P=0.005), HADS Depression (0.08±1.38 vs -3.88±1.48, P<0.001), and HADS Anxiety (0.36±1.98 vs -5.12±2.70, P<0.001) scores, in favour of the patients treated with resveratrol supplements. CONCLUSION: The resveratrol oral supplement is a complementary treatment in cases of wet AMD, highlighting its effectiveness in improving patients' QoL status.
RESUMO
PURPOSE: To evaluate combination treatment with reduced-fluence photodynamic therapy (RDPDT) with Verteporfin and intravitreal bevacizumab, compared to bevacizumab alone, for choroidal neovascularization (CNV) in age-related macular degeneration. METHODS: This was a prospective, randomized comparative study comprising 95 patients with CNV. 49 patients received RDPDT (25 J/cm(2)) followed by intravitreal bevacizumab 1.25 mg one hour later, while 46 received intravitreal bevacizumab alone. Patients were followed for 12 months at four-week intervals with visual acuity (VA) assessment and Optical Coherence Tomography (OCT) of the macula. Bevacizumab re-injections were performed as needed. RESULTS: On average, patients were re-injected 4.45 times in the combination group and 6.96 times in the bavacizumab group (p < 0.001). At 12 months, VA improved by 8.64 letters in the bevacizumab group and by 8.37 letters in the combination group (p = 0.922). CONCLUSION: Adding a reduced-fluence PDT arm in combination with bevacizumab offers similar results to those of intravitreal bevacizumab alone with significantly reduced number of injection repetitions.
