Abstract
AIM To compare the effects of one intravitreal bevacizumab (IVB) injection with three monthly injections for myopic choroidal neovascularization. METHODS Group A included 13 patients treated with one IVB injection; group B included 19 patients treated with three monthly 1.25-mg IVB injections. All patients were followed monthly for 12 months with additional injections performed as needed. The best-corrected visual acuity (BCVA) and the central foveal thickness (CFT) on optical coherence tomography were evaluated before and after treatment. RESULTS The mean logMAR BCVA improved from 0.59 to 0.49 at 12 months in group A (p = 0.21) and from 0.65 to 0.29 in group B (p < 0.001); the improved logMAR BCVA differed significantly between the groups (p < 0.05). The mean CFT decreased from 231 μm at baseline to 150 μm at 12 months in group A (p < 0.05) and from 279 to 156 μm in group B (p < 0.001). During the follow-up, 6 of 13 eyes in group A and 5 of 19 eyes in group B received additional injections. CONCLUSIONS Treatment starting with three monthly IVB injections may achieve better functional outcomes with fewer retreatments compared with treatment starting with one IVB injection.

Abstract
PURPOSE To determine the concentration of vascular endothelial growth factor (VEGF) in the aqueous humour of eyes with myopic choroidal neovascularization (mCNV). METHODS Aqueous humour samples were obtained from 21 eyes of 21 patients with mCNV and from 21 eyes of 21 patients with cataract without CNV or other ocular or systemic diseases (control group). The VEGF concentration in the aqueous humour was measured using an enzyme-linked immunosorbent assay. RESULTS The VEGF concentrations in the aqueous humour of eyes with mCNV ranged from < 20.6 to 200 pg/ml (median 35 pg/ml). The concentrations in the control group ranged from 26 to 218 pg/ml (median 100 pg/ml). The difference between the two VEGF concentrations in the aqueous humour was significant (p < 0.001, Mann--Whitney rank sum test). CONCLUSION The VEGF concentration in the aqueous humour of patients with mCNV is lower than in normal controls. VEGF might localize in or around the CNV in eyes with mCNV.

Abstract
PURPOSE The purpose of this study was to evaluate the safety and efficacy of intravitreal bevacizumab in treatment-naive patients with choroidal neovascularization (CNV) secondary to pathologic myopia over a 2-year interval. METHODS Patients diagnosed with myopic CNV who had not received previous treatment were given intravitreal injections of bevacizumab (2.5 mg/0.1 mL). All patients were retrospectively evaluated using best-corrected visual acuity (BCVA) and central macular thickness (CMT) measured with optical coherence tomography (OCT). RESULTS Twenty-six eyes of 26 patients aged 15-81 years (mean, 42.6 years) were enrolled. OCT images demonstrated that the mean CMT±standard deviation (SD) significantly changed from 270±47 μm at baseline to 228±35, 218±35, 212±25, 210±29, and 209±30 μm in the 1st, 3rd, 6th, 12th, and 24th post-treatment months, respectively (P<0.001 for all). The BCVA in logarithm of the minimum angle of resolution±SD significantly changed from 0.75±0.43 at baseline to 0.57±0.44, 0.42±0.44, 0.39±0.47, 0.41±0.44, and 0.42±0.41 in the 1st, 3rd, 6th, 12th, and 24th post-treatment months, respectively (P<0.001 for all). The mean number of injections was 1.69 (range, 1-4) within the 24-month period. The follow-up period ranged from 24 to 35 months (mean, 28 months). No other ocular or systemic adverse effects were observed. CONCLUSIONS Although the present study lacked a control group, the results in this small series of patients over the 2-year follow-up period indicate that intravitreal injection of 2.5 mg bevacizumab is effective and safe in patients with myopic CNV.

Abstract
PURPOSE The purpose of this study was to evaluate whether combined customized photodynamic therapy (PDT) and bevacizumab in myopic choroidal neovascularization can improve vision and whether it is possible to decrease the frequency and number of intravitreal antiangiogenic injections. METHODS A prospective, consecutive, noncomparative, interventional case series of 36 patients with myopic choroidal neovascularization, treated with an initial dose of PDT and intravitreal bevacizumab 48 hours to 60 hours afterward. Retreatments were carried out as required with monthly bevacizumab and PDT every 3 months if there were relapses. Follow-up lasted 1 year in all cases. RESULTS The mean best-corrected visual acuity increased from 44 letters before the initial treatment to 59.5 letters at the 12-month follow-up (P < 0.01). Compared with initial vision, 94.5% of the eyes had the same or better vision and 5.5% lost fewer than 6 lines of vision. The mean number of PDT treatments was 1.1 per patient, and the mean number of bevacizumab injections was 1.5 per patient. Only 1 initial treatment with PDT + bevacizumab was necessary in 28 cases (77.8%). CONCLUSION Combined personalized PDT + bevacizumab therapy makes it possible to obtain visual results similar to those obtained in monotherapy studies but with fewer intravitreal injections. It appears to be an interesting option for this type of patient.

Abstract
PURPOSE To compare the 1-year functional and anatomical outcomes of intravitreal bevacizumab (IVB) and photodynamic therapy (PDT) in patients with myopic choroidal neovascularization (CNV). METHODS Review of retrospectively collected data of 80 eyes in 80 patients with myopic CNV treated with standard PDT (n = 40) or IVB (1.25 mg/ 0.05 ml) (n = 40). Best-corrected visual acuity (BCVA) and central retinal thickness (CRT) measured with optical coherence tomography (OCT) were compared between the two groups at baseline, 3, 6 and 12 months. RESULTS In the IVB group, mean BCVA was +0.9 ± 0.85 logMAR at baseline. Mean BCVA was significantly better at 3 and 6 months than baseline (p = .0095 and p = .008, respectively) but not at 12 months (p = .065). In the PDT group, mean BCVA was +0.88 ± 0.45 logMAR at baseline, and improved to +0.85 ± 0.62 logMAR at 3 months and to +0.86 ± 0.44 logMAR at 6 months, which was not significantly different from baseline. Mean BCVA then decreased to +0.9 ± 0.54 logMAR at 12 months (p = .85). Mean logMAR VA was significantly better in the IVB group than in the PDT group after 3 months (p = .0043), 6 months (p = .0001) and 12 months (p = .0168). Mean CRT was significantly lower in IVB group than in PDT group at 3, 6 and 12 months (p = .008, p = .038, p = .040, respectively). Chorioretinal atrophy developed in six eyes (15%) treated with IVB and in 24 eyes (60%) treated with PDT at 12 months (p = 3.2 × 10(-5)). CONCLUSIONS Over a 12-month period, intravitreal bevacizumab seems to be superior to photodynamic therapy in controlling myopic CNV in a North-African population.

Abstract
PURPOSE To determine the pre-treatment ocular factors significantly associated with the visual outcome 24 months after intravitreal bevacizumab (IVB) for myopic choroidal neovascularization (mCNV). METHODS A total of 23 eyes of 23 patients with mCNV were treated with IVB followed by as needed therapy. The efficacy of IVB was evaluated by the best-corrected visual acuity (BCVA) at 24 months after the initial treatment. Forward stepwise multiple linear regression analyses were performed to evaluate the influence of pre-treatment factors on the BCVA and the improvement of the BCVA at 24 months. RESULTS The mean pre-IVB BCVA was 0.74 ± 0.30 logarithm of the minimum angle of resolution (logMAR) units, and it improved to 0.43 ± 0.31 logMAR units after 1 month (P < 0.001, paired t-test). The improvement was maintained at 24 months (0.46 ± 0.40, P < 0.005). The mean number of IVB performed during the 24 months was 1.35 ± 0.71. Forward stepwise regression analysis showed that the pre-IVB CNV size (standardized β = 0.52, P < 0.01) and BCVA (standardized β = -0.44, P < 0.05) significantly affected the visual acuity change after 24 months. The CNV size was the only factor that significantly affected the BCVA after 24 months (standardized β=0.56, P < 0.01). CONCLUSIONS IVB with as needed therapy for mCNV led to a rapid and sustained visual improvement. Smaller CNV size was a significant prognostic factor that predicts better visual acuity. Patients with lower pre-treatment BCVA had better visual recovery than those with better pre-treatment BCVA, however, this may be due to a ceiling/floor effect.

Abstract
BACKGROUND Myopic maculopathy is the leading cause of subfoveal choroidal neovascularization (CNV) among patients under 50 years of age. New antiangiogenic drugs are being used off-label to treat myopic CNV and the short-term outcome of these therapies has been reported. The aim of this study is to report the changes in best-corrected visual acuity (BCVA) and optical coherence tomography (OCT) in highly myopic CNV treated by intravitreal bevacizumab at 2 years. METHODS Prospective non-randomized, interventional case series study of 19 highly myopic eyes from 18 patients with subfoveal and juxtafoveal CNV treated by three monthly intravitreal injections of 1.25 mg bevacizumab. Patients were evaluated for BCVA and OCT at baseline and then monthly for 2 years. RESULTS Eleven eyes were naive for treatment and eight eyes had been previously treated by photodynamic therapy. LogMAR BCVA averaged 0.54 (SD 0.25, range 0.2-1.0; Snellen 20/69) at baseline; 0.40 (SD 0.35, range 0.0-1.2; Snellen 20/50) at 1 year; and 0.47 (SD 0.31, range 0.0-1.0; Snellen 20/59) at 2 years (p = 0.04 and p = 0.20, respectively, Student's t test paired data). Re-treatment was performed in four eyes during the first year: three eyes at month six and one eye at month 12. Four eyes required one re-injection during the second year at months 14, 18, 20, and 24. Neither ocular nor systemic adverse reactions were detected. CONCLUSIONS Intravitreal bevacizumab seems to be effective for subfoveal and juxtafoveal CNV in highly myopic eyes. BCVA gain decreases and is no longer significant by the end of the second year.

Abstract
PURPOSE To compare the short-term efficacy and safety of intravitreal ranibizumab versus bevacizumab in treating myopic choroidal neovascularization (CNV). DESIGN Prospective, comparative, randomized, interventional study. METHODS Thirty-two eyes from 32 patients with myopic CNV were consecutively enrolled and randomly treated, in a 1:1 ratio, with intravitreal ranibizumab (0.5 mg) or bevacizumab (1.25 mg) as needed, after the first injection. ETDRS best-corrected visual acuity (BCVA), foveal center thickness (FCT) on optical coherence tomography (OCT), and fluorescein angiographic findings were examined before and after treatment. Patients were followed up for 6 months. RESULTS No statistically significant difference in the BCVA improvement, as well as in the FCT reduction, was found between groups during follow-up (P value at 1, 3, 6 months > .05). Complete resolution of fluorescein leakage was observed in all 16 bevacizumab-treated eyes and in 15 out of 16 (93.7%) ranibizumab-treated eyes. No ocular or systemic adverse effects from treatment were encountered. CONCLUSION This randomized clinical study cannot determine a statistically significant difference in anti-VEGF treatment effect between ranibizumab and bevacizumab for the treatment of CNV secondary to pathologic myopia. A larger study is required to determine the relative efficacy and duration of action of these drugs.

Bevacizumab for choroidal neovascularization secondary to pathologic myopia: Is there a decline of the treatment efficacy after 2 years? Graefes Arch Clin Exp Ophthalmol 2010; 248:543-50.

Abstract
BACKGROUND The Verteporfin in Photodynamic Therapy (VIP) Study failed to prove a statistically significant benefit for myopic choroidal neovascularization (CNV) at the end of the second year. Therefore, we wanted to evaluate whether the early effects seen under anti-VEGF treatment can be maintained over longer follow-up intervals. METHODS This consecutive case series included all patients at the Centre for Ophthalmology, Tuebingen, with a 2-year follow-up after treatment with 1.25 mg of bevacizumab alone or in combination with photodynamic therapy. Twenty-one eyes from 19 patients were analyzed in the retrospective evaluation of best-corrected visual acuity (BCVA) and central foveal thickness (CFT). RESULTS Mean logMAR BCVA improved from 0.64 at baseline to 0.55 after 1 year (p = 0.32) and remained 0.55 at 2 years (p = 0.23). A subgroup analysis showed that mean logMAR BCVA in the monotherapy group improved from 0.7 to 0.5 at 2 years (n = 11, p = 0.06). In the combined therapy group, mean logMAR BCVA changed from 0.55 to 0.59 at 2 years (n = 10, p = 0.69). Mean CFT decreased significantly in both groups by 168 microm (p < 0.001) and 76 microm (p < 0.05) in the monotherapy and in the combined groups, respectively. No complications or adverse effects were observed. CONCLUSION Although the limitations of the study design have to be acknowledged and carefully discussed, we found no obvious superiority of a combined treatment for myopic CNV, at least in terms of the functional outcome and the injection frequency. The results indicate that bevacizumab might be beneficial in the treatment of patients with CNV secondary to pathologic myopia.

Inclusion criteria were age 50 years or older, greatest linear dimension (GLD) 1200 to 3000 microm, and baseline best-corrected visual acuity (BCVA) 20/200 to 20/40. INTERVENTION PROCEDURES: Patients received either PDT or IVB (1 mg/40 microL) throughout the study, with re-treatment when necessary. MAIN OUTCOME MEASURES BCVA and visual gain/loss at 3, 6, 12, 18, and 24 months after the initial treatment. RESULTS Age, BCVA, location of CNV, refractive error, and symptom duration at baseline did not differ significantly between groups. BCVA was significantly improved at 3 to 12 months (P < .05); however, the significance was lost at 18 and 24 months in the IVB group. The PDT group showed no significant improvement within the first year, and vision slowly worsened after 12 months, becoming significantly worse at 18 and 24 months compared to baseline (P< .01). BCVA was significantly higher in the IVB group at 6 months (P< .05), and 12 months or further (P < .01). Visual gain was significantly greater in the IVB group at 6, 12, 18, and 24 months (P < .05 for 6, 18, and 24 months and P < .01 for 12 months). CONCLUSIONS These findings indicate that the effects of PDT and IVB have a different time course, and that IVB provides a significantly better BCVA than PDT for mCNV over the long-term.

A study of efficacy and safety. Graefes Arch Clin Exp Ophthalmol 2009; 248:497-502. [PMID: 19916015 DOI: 10.1007/s00417-009-1232-1] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/21/2009] [Revised: 10/20/2009] [Accepted: 10/22/2009] [Indexed: 10/20/2022] Open
Abstract
BACKGROUND To evaluate the efficacy and safety of low-fluence-rate photodynamic therapy (LFPDT) to treat choroidal neovascularisation (CNV) secondary to pathological myopia (PM). METHODS Twenty-five eyes with CNV in PM underwent LFPDT, with a standard dose of verteporfin and timing but adopting fluence and irradiance rates reduced to 25 mJ/cm2 and 300 mW/cm2, respectively. Best corrected visual acuity (BCVA) was measured and biomicroscopy and fluorescein angiography (FA) were evaluated. Particular attention was paid to choroidal hypoperfusion, and to changes (depigmentation/atrophy) at the RPE level in areas exposed to laser light. RESULTS After a mean follow-up of 13.4+/-2.46 months (range: 12-21), and 1.37+/-0.66 treatments (range: 1-3), BCVA was stable in 29 (91%) eyes. Two (6%) patients gained more than three lines and one (3%) eye lost more than three lines. Mean greatest linear dimension did not change significantly (p=0.08) at the end of follow-up. RPE depigmentation was present in six eyes (18%) and no patient showed RPE atrophy. CONCLUSIONS LFPDT is effective and safe for CNV secondary to PM treatment, stabilizing visual acuity and lesion size and determining only mild RPE changes. Further controlled studies are needed to demonstrate the long-term efficacy and safety of this treatment option.

Comparison of visual outcome and regression pattern of myopic choroidal neovascularization after intravitreal bevacizumab or after photodynamic therapy. Am J Ophthalmol 2009; 148:396-408. [PMID: 19427991 DOI: 10.1016/j.ajo.2009.03.026] [Citation(s) in RCA: 51] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/02/2009] [Revised: 03/11/2009] [Accepted: 03/16/2009] [Indexed: 10/20/2022]
Abstract
PURPOSE To compare the 1-year visual and anatomic outcomes in myopic eyes with choroidal neovascularization (CNV) treated by intravitreal bevacizumab (IVB) to those treated by photodynamic therapy (PDT). DESIGN An open-label, consecutive, interventional case series. METHODS Forty-four eyes of 42 consecutive patients with myopic CNV treated with PDT, and 43 eyes of 43 consecutive patients with myopic CNV treated with IVB, were evaluated. For control, 74 eyes of 71 consecutive patients with untreated myopic CNV were evaluated. The comparison of best-corrected visual acuity (BCVA) using analysis of covariance (ANCOVA) during the 12-month follow-up period was performed among the 26 IVB-treated patients without prior treatment, 35 PDT-treated patients without prior treatment, and 71 nontreated controls. RESULTS Thirty-nine of the IVB-treated eyes (91%) had angiographic closure, and 21 (48.8%) had an improvement of >2 lines in the BCVA at 1 year. IVB-treated patients had significantly better BCVA than PDT-treated and control eyes at 1 year. The CNV size continued to decrease during the 12-month follow-up in the successfully treated IVB eyes, and the size did not decrease, or even increased, in 65% of the successfully treated PDT eyes. Chorioretinal atrophy developed significantly more frequently in PDT-treated than IVB-treated eyes. CONCLUSIONS IVB is more effective for myopic CNV than PDT. The differences in the regression pattern of CNVs and the rate of chorioretinal atrophy probably explain the better BCVA in the IVB-treated eyes.

Abstract
PURPOSE To evaluate the efficacy of intravitreal ranibizumab for the primary treatment of myopic choroidal neovascularization (CNV). METHODS Sixteen eyes of 16 consecutive patients who received 3 monthly injections of intravitreal ranibizumab for primary treatment of myopic CNV were reviewed. Additional ranibizumab injections were performed in eyes with persistent or recurrent CNV after 3 months. RESULTS The mean age of the patients was 60.8 years, and the spherical equivalent refractive error was -10.9 D. The mean logMAR best-corrected visual acuity at baseline was 0.58 (20/76). At 1 month and 12 months, the mean logMAR best-corrected visual acuity improved significantly to 0.39 (20/49) and 0.28 (20/37), respectively (P = 0.001 and P < 0.001, respectively). The mean improvement at 12 months was 3.0 lines, and 12 (75.0%) eyes had improvement of 2 or more lines. Fifteen (93.8%) eyes had angiographic closure at 3 months and 1 (6.2%) required further treatment because of persistent leakage at 3 months. Two (12.5%) patients had recurrence of CNV and required retreatment between 3 months and 9 months. Optical coherence tomography showed significant reduction in the mean central foveal thickness after treatment (P < 0.001). None of the patients developed any ocular or systemic side effects associated with intravitreal ranibizumab. CONCLUSION Intravitreal ranibizumab appeared to be effective for the primary treatment of myopic CNV, with a high proportion of patients sustaining visual gain after treatment.
