To compare intravitreal bevacizumab (IVB) and intravitreal ranibizumab (IVR) in the treatment of subfoveal choroidal neovascularization associated with pathologic myopia. Fifty-five patients fulfilling inclusion and exclusion criteria were randomized either to IVB or to IVR. After the first injection, re-treatments were performed on a pro re nata basis in monthly examinations over an 18-month follow-up. Primary outcome measures were the change in mean best-corrected visual acuity and the proportion of eyes improving in best-corrected visual acuity by >1 and >3 lines at the 18-month examination. Forty-eight eyes received the treatment and were subsequently included in the analysis. At the 18-month examination, a significant improvement of 1.7 lines and 1.8 lines compared with baseline were noticed in the IVR and IVB subgroups, respectively. The difference in the final mean best-corrected visual acuity between the groups was not significant. A 3-line gain or higher was noted in 30% of eyes in the IVR subgroup and 44% of eyes in the IVB subgroup. Although both groups attained a significant improvement in central macular thickness, the IVR subgroup achieved a faster central macular thickness reduction. A significantly lower number of injections were administered in the IVR subgroup (2.5) compared with the IVB subgroup (4.7; P < 0.001). Intravitreal ranibizumab and IVB are effective in the treatment of subfoveal myopic choroidal neovascularization. Intravitreal ranibizumab achieved greater efficacy than IVB in terms of the mean number of injections administered.

Central serous chorioretinopathy (CSC) is a retinal disorder that primarily affects young (20- to 50-year-old) white men, although it is seen occasionally in older patients and females. CSC is characterized by avascular focal leakage through the retinal pigment epithelium (RPE), resulting in serous detachment of the neurosensory retina. The course is usually self-limiting and in most cases resolves spontaneously within a 3-month period, with visual acuity usually recovering to 20/30 or better. However, chronic CSC may develop as a consequence of recurrences or persistent neurosensory detachment, and can result in progressive RPE atrophy and permanent visual loss. A primary involvement of the RPE and choroidal vascularization play a significant role in the pathogenesis of CSC and the current treatment options attempt to restore the functions of the RPE and the normal choroidal vasculature. The aim of the current review is to provide an overview of the current therapeutical approaches to CSC, including observation, laser treatment, photodynamic therapy with verteporfin, intravitreal anti-vascular endothelial growth factor therapy and the mineralocorticoid receptor antagonists.

Purpose: To evaluate the effects of intravitreal ranibizumab injections in the treatment of choroidal neovascularization with large submacular hemorrhage secondary to age-related macular degeneration. Methods: Prospective interventional case series. Patients presenting occult choroidal neovascularization with flat large submacular hemorrhage >50% of the entire lesion were considered. The protocol required 3 monthly consecutive injections, followed by repeat injections over the 12-month follow-up on the basis of optical coherence tomography parameters and angiographic features. Results: Twenty-three patients were enrolled in the study and prospectively followed up. Mean best-corrected visual acuity and mean central macular thickness at the baseline were 0.82 ± 0.22 (logarithm of the minimum angle of resolution ± standard deviation) and 342 ± 56 µm, respectively. At 12-month examination, mean visual acuity improved significantly to 0.68 ± 0.41 (P = 0.04), and mean central macular thickness decreased to 236 ± 26 µm (P < 0.0001). A progressive resolution of macular bleeding was registered in 22 of 23 patients. No side effect or complication was registered. Conclusion: Intravitreal ranibizumab can be considered a beneficial approach for the management of choroidal neovascularization with flat large submacular hemorrhage secondary to age-related macular degeneration.

Objective To compare the effectiveness of photodynamic therapy (PDT) vs intravitreal bevacizumab injection in patients with subfoveal choroidal neovascularization (CNV) secondary to multifocal choroiditis (MC). Methods Patients affected by subfoveal CNV associated with MC referred for clinical evaluation from March 1, 2005, to July 31, 2008, were considered for this pilot randomized clinical trial. Twenty-seven patients were included in the study and followed up from March 15, 2005, through April 30, 2009. After randomization, patients receiving PDT were treated according to the Treatment of Age-Related Macular Degeneration With Photodynamic Therapy protocol, whereas patients receiving intravitreal bevacizumab injection, after a loading phase of 3 monthly injections, were examined monthly and re-treated on the basis of detection of fluid on optical coherence tomography and/or leakage on fluorescein angiography. Main Outcome Measures The primary outcome measure was the 5- and 15-letter change on the Early Treatment of Diabetic Retinopathy Study charts at 12-month examinations compared with baseline. Secondary outcomes included central macular thickness changes. Results Thirteen and 14 patients were randomized to PDT and bevacizumab treatment, respectively. At the 12-month examination, 5 of 14 eyes treated with bevacizumab and 0 of 13 eyes treated with PDT experienced a best-corrected visual acuity gain of greater than 3 lines (P = .04). Twelve eyes in the bevacizumab group and 6 eyes in the PDT group gained more than 1 line (P = .04). The central macular thickness showed a progressive reduction in both subgroups without a significant difference compared with the baseline values. Conclusions Greater beneficial effects can be achieved using intravitreal bevacizumab injection rather than PDT for the treatment of subfoveal CNV secondary to MC. Larger multicenter investigations are needed to confirm our preliminary results. Application to Clinical Practice Currently, there is no precise indication regarding the best therapeutic approach to subfoveal CNV secondary to MC. This investigation was designed to verify whether intravitreal bevacizumab injection has a more beneficial effect with respect to PDT.
