Abstract
BACKGROUND The aim of this review was to systematically summarize the current knowledge on type 3 macular neovascularization (MNV3) in age-related macular degeneration (AMD). SUMMARY Recent histopathologic and multimodal imaging findings led to the consensus definition of the new term "type 3 macular neovascularization" in AMD. MNV3 originates in the deep vascular plexus as a neovascular process without connection with the retinal pigment epithelium in the initial stages. This type has numerous clinical and pathomorphologic features that separate it from the other two types of MNV in AMD. Besides, its frequency appears to be higher than previously thought. In optical coherence tomography (OCT), MNV3 can be classified into stages 1-3. Hyperreflective foci in the outer retina possibly represent a precursor lesion. In addition, MNV3 is characterized by a strong association with reticular pseudodrusen, a high rate of bilaterality, close associations with advanced age and arterial hypertension, decreased choroidal thickness, and decreased choriocapillaris flow signals. Data from latest anti-vascular endothelial growth factor studies in MNV3 suggest that the OCT biomarkers in intraretinal and subretinal fluids should be interpreted differently than in the other types. Additionally, data from MNV3 eyes should be analyzed separately, allowing optimal type-specific treatment strategies in the future. KEY MESSAGES This review highlights the need for accurate characterization of neovascular AMD lesions and an MNV type-specific approach, particularly for MNV3.

Anti-vascular endothelial growth factor monotherapy or combined with verteporfin photodynamic therapy for retinal angiomatous proliferation: a systematic review with meta-analysis. Front Pharmacol 2023; 14:1141077. [PMID: 37377929 PMCID: PMC10291099 DOI: 10.3389/fphar.2023.1141077] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/09/2023] [Accepted: 05/19/2023] [Indexed: 06/29/2023] Open
Abstract
Purpose: To assess functional and anatomical outcomes of intravitreal anti-Vascular Endothelial Growth Factor (anti-VEGF) monotherapy versus combined with verteporfin Photodynamic Therapy (PDT) for Retinal Angiomatous Proliferation (RAP). Methods: Studies reporting outcomes of intravitreal anti-VEGF monotherapy and/or in combination with verteporfin PDT in RAP eyes with a follow-up ≥ 12 months were searched. The primary outcome was the mean change in best corrected visual acuity (BCVA) at 12 months. Mean change in central macular thickness (CMT) and mean number of injections were considered as secondary outcomes. The mean difference (MD) between pre- and post-treatment values was calculated along with 95% Confidence Interval (95% CI). Meta-regressions were performed to assess the influence of anti-VEGF number of injections on BCVA and CMT outcomes. Results: Thirty-four studies were included. A mean gain of 5.16 letters (95% CI = 3.30-7.01) and 10.38 letters (95% CI = 8.02-12.75) was shown in the anti-VEGF group and combined group, respectively (anti-VEGF group vs. combined group, p < 0.01). A mean CMT reduction of 132.45 µm (95% CI = from -154.99 to -109.90) and 213.93 µm (95% CI = from -280.04 to -147.83) was shown in the anti-VEGF group and combined group, respectively (anti-VEGF group vs. combined group, p < 0.02). A mean of 4.9 injections (95% CI = 4.2-5.6) and 2.8 injections (95% CI = 1.3-4.4) were administered over a 12-month period in the anti-VEGF group and combined group, respectively. Meta-regression analyses showed no influence of injection number on visual and CMT outcomes. High heterogeneity was found across studies for both functional and anatomical outcomes. Conclusion: A combined approach with anti-VEGF and PDT could provide better functional and anatomical outcomes in RAP eyes compared with anti-VEGF monotherapy.

Ophthalmol Ther 2022; 11:1503-1516. [PMID: 35596037 PMCID: PMC9253227 DOI: 10.1007/s40123-022-00521-y] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/02/2022] [Accepted: 04/29/2022] [Indexed: 12/01/2022] Open
Abstract
INTRODUCTION To evaluate the outcomes of intravitreal aflibercept injections for retinal angiomatous proliferation (RAP) according to disease stage. METHODS This retrospective chart review included 68 eyes of 53 individuals diagnosed as having RAP and 109 neovascular age-related macular degeneration (nAMD) eyes of 109 patients as controls. All patients received intravitreal injections of aflibercept in a real-world setting. The main outcome measures were the changes in the mean of best-corrected visual acuity (BCVA) and central retinal thickness (CRT) as well as the total number of injections received during the 3-year follow-up period. RESULTS The average BCVA and CRT changes in eyes affected by RAP and the controls at 3 years were non-significant. Both populations received a similar number of injections. After 3 years of treatment, patients with RAP had visual decline despite stable anatomical outcomes. Approximately 50% of the eyes with stage II RAP exhibited significant BCVA decline at the end of the third year. Among those eyes that had deteriorated BCVA, persistently worsening BCVA and thinning CRT were observed from year 2 to year 3. CONCLUSION Similar to treating nAMD, intensive injections or aggressive treatment strategies are required to treat RAP to achieve optimal visual outcomes in a real-world setting. The response to aflibercept treatment at the second year is associated with the final visual outcome of eyes with stage II RAP lesions.

Acta Ophthalmol 2022; 100:e270-e277. [PMID: 33821577 PMCID: PMC9292611 DOI: 10.1111/aos.14866] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/16/2020] [Revised: 03/02/2021] [Accepted: 03/16/2021] [Indexed: 11/27/2022]
Abstract
BACKGROUND/AIMS To explore whether the existence and pattern of distribution of macular haemorrhage or exudate can be valuable diagnostic markers for macular neovascularization type 3 (MNV3) in patients with neovascular age-related macular degeneration. METHODS Eighty-three eyes of 83 consecutive treatment naïve patients with stage 3 MNV3 were enrolled. The diagnosis was based on fluorescein angiography (FA) and optical coherence tomography (OCT). Subretinal and intraretinal haemorrhage and dense exudates were evaluated on colour fundus photography. Fluorescein angiography (FA) images and OCT scans were used to identify the axial location of the haemorrhage. 83 patients with MNV1 and 83 with MNV2 were included as two control groups. RESULTS In the MNV3 group, 62 (75%) eyes had intraretinal haemorrhage and 52 (63%) had dense exudates. 73 (88%) eyes had intraretinal haemorrhage and/or dense exudates. 41 (49%) had both pathologies. The intraretinal haemorrhage was flame shaped over the lesion and punctate or semi-punctate further away from it and directed to the fovea. No subretinal haemorrhage was noticed. In the MNV1 and MNV2 groups, 11 (13%) and 24 (29%) eyes had subretinal haemorrhage or dense exudates, respectively. No intraretinal haemorrhage was seen in the two control groups. The prevalence of exudates and haemorrhage (irrespective of its location) was greater in MNV3 than in MNV1 or 2 (p < 0.0001). CONCLUSION The existence and pattern of distribution of intraretinal haemorrhage is pathognomonic of MNV3. It makes (alone or with dense exudates) the diagnose MNV3 possible using fundoscopy or colour fundus photo and without further diagnostic expenditure.

Fayed AE, Fawzi AA. Projection resolved optical coherence tomography angiography to distinguish flow signal in retinal angiomatous proliferation from flow artifact. PLoS One 2019; 14:e0217109.

Abstract
Purpose To investigate whether hyperreflective foci (HRF) exhibit flow projection artifact on OCTA, and study the efficacy of commercial projection artifact removal software (PAR-OCTA, Optovue, Inc), and a custom projection resolved OCTA (PR-OCTA) in distinguishing artifacts from true flow in retinal angiomatous proliferation (RAP). Methods The study included five eyes with HRF representing pigment migration in dry age-related macular degeneration (AMD), five eyes with leaking treatment-naïve RAP, and ten eyes with diabetic hard exudates. We examined flow signal on OCTA cross-sections using PAR, and performed PR-OCTA to study the effect of increasingly stringent projection removal thresholds. Flow signal intensity was analyzed and quantified using imageJ (NIH, Bethesda, MD, USA), by calculating the percentage of red pixels (R) representing flow, compared to green (G) and blue (B) pixels. Results PAR-OCTA cross sections revealed persistent flow signal in all HRF, including RAP, hard exudates and pigment migration. In RAP, PR-OCTA detected intransigent flow, irrespective of the flow removal threshold. Mean R in the five RAP lesions remained higher than mean G and B at the most stringent PR-OCTA threshold (40.96% vs 29.52 and 29.52%, respectively), denoting persistence of flow. In contrast, increasing the PR-OCTA threshold in pigment migration and hard exudates removed the flow signal, with a statistically significant decrease in mean R with increasing threshold. (p = 0.017 and 0.0029, respectively) Conclusion Commercial PAR-OCTA is not completely effective at removing artifactual flow in hard exudates and HRF related to pigment migration. Custom built PR-OCTA, using a sliding scale of threshold, allowed us to distinguish true flow in RAP from artifactual flow in avascular HRF. Further studies are needed to validate the optimum threshold for projection artifact removal, which would preserve true flow in RAP and the small intraretinal capillaries.

Abstract
PURPOSE This prospective case series is aimed at exploring optical coherence tomographic angiography (OCT-A) as a treatment monitoring tool in patients treated for retinal angiomatous proliferation (RAP). METHODS Twelve treatment-naïve RAP patients were included, with a median age of 79 years (range 65-90). Patients were imaged with an experimental 1,040-nm swept-source phase-resolved OCT-A instrument before and after treatment. Treatment consisted of either intravitreal bevacizumab or triamcinolone injections with or without photodynamic therapy (PDT). Abnormal blood flow after treatment was graded as increased, unchanged, decreased, or resolved. RESULTS OCT-A images before and after treatment could be obtained in 9 patients. The median follow-up period was 10 weeks (range 5-19). After various treatments, the RAP lesion resolved in 7 patients, in 1 patient the OCT-A depicted decreased flow in the lesion, and 1 patient showed unchanged abnormal blood flow. Monotherapy with intravitreal bevacizumab injections resolved RAP in 1 out of 2 patients. Combined therapy of bevacizumab with PDT resolved RAP in 6 out of 7 patients. CONCLUSIONS OCT-A visualized resolution of abnormal blood flow in 7 out of 9 RAP patients after various short-term treatment sequences. OCT-A may become an important noninvasive monitoring tool for optimizing treatment strategies in RAP patients.

Abstract
BACKGROUND To evaluate the short-term efficacy of intravitreal injections of aflibercept (IVA) to treat retinal angiomatous proliferation (RAP) and identify factors related to functional outcomes. METHODS This retrospective case series consisted of 19 eyes in 19 patients with RAP. All 19 eyes received 3 monthly consecutive IVA. The primary outcome measures were best-corrected visual acuity (BCVA) and central retinal thickness (CRT) after the last IVA. RESULTS Of the 19 treated eyes, 8 (42%) were pre-treated with 1 dose of bevacizumab one month prior to the initiation of treatment with aflibercept. BCVA was significantly improved and CRT was significantly reduced after 3 consecutive IVAs (P = 0.014 and P = 0.0002, respectively). Stabilization or improvement in BCVA was observed in 17 eyes (90%) treated with IVA. Eyes with baseline fibrovascular pigment epithelial detachment (PED) showed no significant gain in BCVA, and fibrovascular PED was negatively correlated with final BCVA (Spearman's correlation coefficient = - 0.481, P = 0.037). The mean follow-up was 3.5 ± 0.5 months. CONCLUSIONS In this short-term study, three consecutive IVAs showed efficacy for improving vision and reducing retinal edema in RAP patients. Eyes with fibrovascular PED showed poorer responses, and the presence of fibrovascular PED at baseline was negatively correlated with visual outcomes.

Abstract
Purpose To evaluate the 12-month outcome of intravitreal anti-vascular endothelial growth factor therapy in eyes with bilateral retinal angiomatous proliferation (RAP). Methods This retrospective observational study included 38 eyes of 19 patients with stage 1 or 2 bilateral RAP at diagnosis. The eyes of patients who exhibited different baseline best-corrected visual acuity (BCVA) values in both eyes were assigned to one of two groups—the better (n=13) and worse (n=13) visual acuity groups. The BCVA values in both groups were compared to those at baseline and at 12 months. In addition, the 12-month changes in BCVA were compared between the two groups. The association between the optical coherence tomography findings at diagnosis and the 12-month BCVA was also analyzed. Results The values of mean baseline and 12-month BCVA in the better visual acuity group (13 eyes) were 0.48 ± 0.19 and 0.58 ± 0.29, respectively, and those in the worse visual acuity group (13 eyes) were 0.83 ± 0.20 and 0.90 ± 0.31. The 12-month changes in BCVA were not significantly different between the two groups (p=0.786). Among the six patients with equivalent baseline BCVA in both eyes, four patients (66.7%) exhibited 1 to 2 lines or ≥3 lines of difference in BCVA between eyes at 12 months. Eyes without pigment epithelial detachment (PED) at diagnosis exhibited significantly better BCVA at 12 months than eyes with PED (p=0.021). Conclusions Better baseline visual acuity was associated with better BCVA at 12 months posttreatment in patients with bilateral RAP. However, equivalent baseline visual acuity in both eyes might not guarantee similar treatment outcomes. In addition, the absence of PED is predictive of better visual outcome.

Abstract
As a progressive chronic disease, age-related macular degeneration (AMD) is the leading cause of irreversible vision impairment worldwide. Experimental and clinical evidence has demonstrated that vascular endothelial growth factor (VEGF) plays a vital role in the formation of choroidal neovascularization. Intravitreal injections of anti-VEGF agents have been recommended as a first-line treatment for neovascular AMD. However, persistent fluid or recurrent exudation still occurs despite standardized anti-VEGF therapy. Patients suffering from refractory or recurrent neovascular AMD may develop mechanisms of resistance to anti-VEGF therapy, which results in a diminished therapeutic effect. Until now, there has been no consensus on the definitions of refractory neovascular AMD and recurrent neovascular AMD. This article aims at clarifying these concepts to evaluate the efficacy of switching drugs, which contributes to making clinical decision more scientifically. Furthermore, insight into the causes of resistance to anti-VEGF therapy would be helpful for developing possible therapeutic approaches, such as combination therapy and multi-target treatment that can overcome this resistance.

Abstract
Purpose To compare the effects of intravitreal ranibizumab in monotherapy (group A) and combined with photodynamic therapy (PDT) with verteporfin (group B) in retinal angiomatous proliferation (RAP) treatment. Methods This was a multicentric, prospective, randomized clinical study conducted with parallel groups. The study eye in both groups received ranibizumab on days 1, 30, and 60 (loading dose); group B received PDT additionally on day 1. Early Treatment Diabetic Retinopathy Study (ETDRS) visual acuity (VA) testing and optical coherence tomography were performed monthly, and fluorescein angiography and indocyanine green angiography were performed quarterly. Retreatment criteria were leakage in fluorescein angiography or indocyanine green angiography, mean foveal thickness increase ≥100 µm, or VA decrease ≥5 letters. Results Twenty patients were recruited (ten patients in each group). Six eyes had previous treatment (three eyes in group A and three eyes in group B), so only 14 eyes were naïve. At 12-month follow-up, mean VA improved +1.5 letters in group A and +5.6 letters in group B (analysis of variance test; P>0.05). Two patients (20%) in both groups gained ≥15 letters (chi-square test; P>0.05). Mean changes in greatest linear dimension and in foveal thickness were not statistically significant between groups of treatment (analysis of variance test; P>0.05). Mean retreatments per patient were 1.8 (group A) and 0.9 (group B) (Mann–Whitney U-test; P>0.05). One patient died due to underlying disease not related to study medication. Conclusion Intravitreal ranibizumab administered in monotherapy or combined with PDT was efficacious in terms of VA stabilization in patients with RAP.

Abstract
PURPOSE To compare baseline characteristics, visual acuity (VA), and morphologic outcomes between eyes with retinal angiomatous proliferation (RAP) and all other eyes among patients with neovascular age-related macular degeneration (NVAMD) treated with anti-vascular endothelial growth factor (VEGF) drugs. DESIGN Prospective cohort study within the Comparison of Age-Related Macular Degeneration Treatments Trials (CATT). PARTICIPANTS Patients with NVAMD. METHODS Reading center staff evaluated digital color fundus photographs, fluorescein angiography (FA) images, and optical coherence tomography (OCT) scans of eyes with NVAMD treated with either ranibizumab or bevacizumab over a 2-year period. Retinal angiomatous proliferation was identified by the intense intra-retinal leakage of fluorescein in combination with other associated features. MAIN OUTCOME MEASURES Visual acuity; fluorescein leakage; scar; geographic atrophy (GA) on FA; retinal thickness, fluid, and subretinal hyperreflective material (SHRM) on OCT; and the number of intravitreal anti-VEGF injections at 1 and 2 years. RESULTS Retinal angiomatous proliferation was present in 126 of 1183 (10.7%) study eyes at baseline. Mean VA improvement from baseline was greater (10.6 vs. 6.9 letters; P = 0.01) at 1 year, but similar at 2 years (7.8 vs. 6.2 letters; P = 0.34). At 1 year, eyes with RAP were more likely to have no fluid (46% vs. 26%; P < 0.001) on OCT, no leakage on FA (61% vs. 50%; P = 0.03), and greater reduction in foveal thickness (-240 μm vs. -161 μm; P < 0.001). They were more likely to demonstrate GA (24% vs. 15%; P = 0.01) and less likely to have scarring (17% vs. 36%; P < 0.001) or SHRM (36% vs. 48%; P = 0.01). These results were similar at 2 years. The mean change in lesion size at 1 year differed (-0.27 DA vs. 0.27 DA; P = 0.02), but was similar at 2 years (0.49 DA vs. 0.79 DA; P = 0.26). Among eyes treated PRN, eyes with RAP received a lower mean number of injections in year 1 (6.1 vs. 7.4; P = 0.003) and year 2 (5.4 vs. 6.6; P = 0.025). CONCLUSIONS At both 1 and 2 years after initiation of anti-VEGF treatment in CATT, eyes with RAP were less likely to have fluid, FA leakage, scar, and SHRM and more likely to have GA than eyes without RAP. Mean improvement in VA was similar at 2 years.

Abstract
PURPOSE To study patients diagnosed with retinal angiomatous proliferation (RAP) based on conventional imaging techniques with phase-resolved Doppler optical coherence tomography (OCT) to detect and localize blood flow in RAP lesions; and to compare these findings to conventional imaging, which are mostly invasive and give limited information concerning intra- and transretinal blood flow. DESIGN Single-center, consecutive observational case series. METHODS Twelve treatment-naïve patients diagnosed with RAP based on fundus examination, fluorescein angiography, and indocyanine green angiography were included. Median age was 79 years (range 65-90). Patients were imaged with an experimental 1040 nm swept-source phase-resolved Doppler OCT instrument. Abnormal flow was defined as intraretinal neovascularization or retinal choroidal anastomosis. RESULTS In 11 patients adequate phase-resolved Doppler OCT images were obtained showing abnormal blood flow in the RAP lesion. In 4 patients a retinal choroidal anastomosis was found, 3 patients showed intraretinal neovascularization connected with a pigment epithelial detachment, 2 patients showed only intraretinal neovascularization, and in 2 patients flow was limited to the subretinal or sub-retinal pigment epithelial space. CONCLUSIONS Phase-resolved Doppler OCT is able to detect and localize abnormal blood flow within RAP lesions. Blood flow was mostly confined to the intraretinal structures with or without a connecting pigment epithelial detachment; in one-third of patients a retinal choroidal anastomosis was detected. The potential of angiography with phase-resolved Doppler OCT to accurately distinguish between normal and pathologic blood flow in addition to structural OCT data without invasive procedures will help to further elucidate both retinal and choroidal vascular pathologies like RAP.

Abstract
Anti-vascular endothelial growth factor (anti-VEGF) agents represent the current standard of care for neovascular age-related macular degeneration (nAMD). Although effective in a majority of cases, a significant proportion of patients have persisting retinal exudation despite regular anti-VEGF therapy. This exudation is considered to produce poorer visual outcomes in these patients. Some of these patients may have misdiagnosed nAMD variants such as polypoidal choroidal vasculopathy; however, the majority of these eyes have what has been termed treatment-resistant nAMD. Currently, the best way to care for these patients is uncertain. Here, we review the evidence for different approaches to the management of treatment-resistant nAMD, including high-dose anti-VEGF therapy, combination regimes and switching of anti-VEGF agents, and discuss possible therapeutic approaches for patients with treatment-resistant nAMD.

Abstract
BACKGROUND Vision loss due to vascular disease of the retina is a leading cause of blindness in the world. Retinal angiomatous proliferation (RAP) is a subgroup of neovascular age-related macular degeneration (AMD), whereby abnormal blood vessels develop in the retina leading to debilitating vision loss and eventual blindness. The novel mouse strain, neoretinal vascularization 2 (NRV2), shows spontaneous fundus changes associated with abnormal neovascularization. The purpose of this study is to characterize the induction of pathologic angiogenesis in this mouse model. METHODS The NRV2 mice were examined from postnatal day 12 (p12) to 3 months. The phenotypic changes within the retina were evaluated by fundus photography, fluorescein angiography, optical coherence tomography, and immunohistochemical and electron microscopic analysis. The pathological neovascularization was imaged by confocal microscopy and reconstructed using three-dimensional image analysis software. RESULTS We found that NRV2 mice develop multifocal retinal depigmentation in the posterior fundus. Depigmented lesions developed vascular leakage observed by fluorescein angiography. The spontaneous angiogenesis arose from the retinal vascular plexus at postnatal day (p)15 and extended toward retinal pigment epithelium (RPE). By three months of age, histological analysis revealed encapsulation of the neovascular lesion by the RPE in the photoreceptor cell layer and subretinal space. CONCLUSIONS The NRV2 mouse strain develops early neovascular lesions within the retina, which grow downward towards the RPE beginning at p15. This retinal neovascularization model mimics early stages of human retinal angiomatous proliferation (RAP) and will likely be a useful in elucidating targeted therapeutics for patients with ocular neovascular disease.

Abstract
PURPOSE To evaluate the efficacy of intravitreal ranibizumab with a "pro re nata" regimen in the treatment of nonsubfoveal neovascular membranes secondary to age-related macular degeneration. METHODS Retrospective noncomparative case series. Thirty-one eyes with naive nonsubfoveal neovascularization secondary to age-related macular degeneration were consecutively enrolled and treated with ranibizumab intravitreal injections according to a pro re nata regimen. The follow-up was performed monthly up to 6 months and quarterly up to 2 years (25 patients). Early treatment diabetic retinopathy study best-corrected visual acuity and lesion size analysis with fluorescein angiography were recorded. RESULTS The mean baseline early treatment diabetic retinopathy study best-corrected visual acuity worsened from 20/40 (0.28 logMAR) at baseline to 20/50 (0.42 logMAR) at 1-year follow-up and 20/60 (0.53 logMAR) at 2-year follow-up. The mean lesions size nearly doubled from baseline at the 2-year follow up (1.19-2.47 mm). Twenty-two patients had one or more recurrences at 1-year follow-up. All 25 patients developed a recurrence at 2 years with 7 cases developing a recurrence by 12 months. Twelve cases progressed to subfoveal lesions by the 24-month visit. CONCLUSION Other regimens described in the literature might result in a more the satisfactory outcome using more frequent follow-up and more frequent intravitreal injections.

Abstract
PURPOSE To evaluate the effects of intravitreal bevacizumab and ranibizumab treatments in retinal angiomatous proliferation (RAP). METHODS Fifty patients affected by RAP were randomly assigned either to intravitreal bevacizumab injection (IVBI) or intravitreal ranibizumab injection (IVRI). After a loading phase including three consecutive monthly injections, the retreatment was administered in cases of persistent RAP. The primary outcome measures were the mean changes in BCVA between the two treatment groups, and the proportion of eyes gaining 1 and 3 lines at the end of the follow-up. Secondary outcomes included central macular thickness (CMT) changes and progression to more advanced stages of RAP. RESULTS Fifty patients affected by stage 1 and 2 RAP were recruited. Twenty-six and 24 patients received IVBI and IVRI, respectively. At the baseline, mean best corrected visual acuity (BCVA) values were 0.59 ± 0.21 (LogMAR ± SD, approximately corresponding to 20/80 Snellen Equivalent-SE) in IVBI group and 0.66 ± 0.33 (approximately 20/90 SE) in IVRI group with no statistical difference. At 12-month examination, both groups showed a statistically significant improvement in the BCVA, with a final mean value of 0.43 ± 0.24 (approximately 20/54 SE) in IVBI group and 0.50 ± 0.32 (approximately 20/63 SE) in the IVRI group. A BCVA gain of 1 and 3 lines was registered in 20 and 8 eyes, respectively, in the IVBI group. Similarly, 17 and 7 eyes showed an improvement of 1 or 3 lines, respectively, in the IVRI group. The CMT reduced significantly from baseline to 12-month examination in both groups. A lower proportion of eyes with complete pigment epithelium detachment resolution was noted in the IVBI group than in the IVRI group (40% versus 90%). CONCLUSIONS Our study shows that both IVBI and IVRI are equally effective in improving the BCVA over a 1-year follow-up in eyes affected by stage 1 and 2 RAP.

Abstract
Background The purpose of this study was to evaluate the angiographic results of retinal-retinal anastomosis (RRA) and retinal-choroidal anastomosis (RCA) for eyes with retinal angiomatous proliferation (RAP) after treatment with intravitreal bevacizumab injections as monotherapy or intravitreal bevacizumab combined with photodynamic therapy. Methods In this interventional, consecutive case series, we retrospectively reviewed five naïve eyes from four patients (mean age 80 years) treated with three consecutive monthly intravitreal bevacizumab (1.25 mg/0.05 mL) injections as initial treatment, and followed up for at least 3 months. In cases with over 3 months of follow-up and having recurrence of RAP or leakage by fluorescein angiography, retreatment was performed with a single intravitreal bevacizumab injection and photodynamic therapy. Results Indocyanine green angiography showed RRA in three eyes with subretinal neovascularization and RCA in two eyes with choroidal neovascularization at baseline. At 3 months after baseline (month 3), neither the RRA nor RCA was occluded in any eye on indocyanine green angiography. Retreatment with intravitreal bevacizumab plus photodynamic therapy was performed in three eyes at months 3 (persistent leakage on fluorescein angiography), 6, and 7 (recurrence of RAP lesion), which achieved obvious occlusion of the RRA and RCA. Mean best-corrected visual acuity improved from 0.13 to 0.21 at month 3 (P = 0.066). No complications or systemic adverse events were noted. Conclusion Although intravitreal bevacizumab for RAP was effective in improving visual acuity during short-term follow-up, intravitreal bevacizumab could not achieve complete occlusion of RRA and RCA, which could lead to recurrence of a RAP lesion and exudation. Retreatment with intravitreal bevacizumab plus photodynamic therapy ultimately achieved complete occlusion of the RRA and RCA.

DESIGN Prospective, consecutive, interventional case series. PARTICIPANTS Eighty eyes (40 affected eyes with neovascular AMD and 40 unaffected fellow eyes) of 40 patients. METHODS Forty eyes with neovascular AMD were treated with 0.5-mg IVRs monthly for 3 months and received additional IVRs as needed over the following 9-month period. Subfoveal choroidal thickness in all 80 eyes was measured by use of enhanced depth imaging optical coherence tomography images before and after starting the IVRs. MAIN OUTCOME MEASURES Changes in subfoveal choroidal thickness after treatment by IVRs over a 12-month period. RESULTS Twenty-three eyes (57.5%) were diagnosed with typical neovascular AMD, 16 eyes (40%) were diagnosed with polypoidal choroidal vasculopathy, and 1 eye (2.5%) was diagnosed with retinal angiomatous proliferation. Fifteen eyes (38%) had received some previous treatments for the neovascular lesion before undergoing the IVRs. The mean best-corrected visual acuity of the affected eyes was improved from 0.54 logarithm of the minimum angle of resolution units at baseline to 0.42 at 12 months (P = 0.020). The mean subfoveal choroidal thickness in the affected eyes decreased from 244±62 μm at baseline to 234±66 μm at 1 month (P = 0.013), 226±68 μm at 3 months (P<0.001), 229±67 μm at 6 months (P = 0.002), and 226±66 μm at 12 months (P = 0.002; the change ratio, 93%), whereas that in the unaffected eyes changed from 237±80 μm at baseline to 238±83 μm at 12 months (P = 0.78). In the affected eyes, the change ratio of subfoveal choroidal thickness at 12 months was not correlated with the number of IVRs (mean, 5.8±2.9). Subfoveal choroidal thickness demonstrated a similar trend toward decreasing during the following period independent of the subtypes of neovascular AMD or the treatment histories. CONCLUSIONS Subfoveal choroidal thickness decreased after IVRs in eyes with neovascular AMD. Intravitreal injections of ranibizumab may provide a pharmacologic effect not only on the neovascular lesion but also on the underlying choroid.

Abstract
PURPOSE Neovascular age-related macular degeneration (AMD) is a leading cause of blindness, with an increasing incidence as the elderly population expands. Large, multi-center, randomized, clinical trials have been conducted exploring the safety and efficacy of anti-VEGF treatments. This paper aims to discuss the safety and efficacy of pegaptanib, ranibizumab, aflibercept and bevacizumab. New therapeutic agents and treatment strategies are also discussed. PROCEDURES Evidence available from prospective, multicenter, clinical studies and from a selective literature search is utilized to present the results of VEGF inhibition in neovascular AMD and to generate evidence-based recommendations. RESULTS Anti-VEGF treatment is indicated in choroidal neovascularization with active disease and produces a significant benefit in visual acuity. CONCLUSIONS With the advent of anti-VEGF therapy, the prognosis of choroidal neovascularization has changed dramatically. Data from well-conducted clinical trials suggest that approved anti-VEGF drugs are effective and well tolerated.

Abstract
PURPOSE To clarify the efficacy of combined therapy with intravitreal ranibizumab injections and photodynamic therapy (PDT) in patients with symptomatic retinal angiomatous proliferation. DESIGN Retrospective, interventional, consecutive case series. METHODS We retrospectively reviewed 20 treatment-naïve eyes of 16 patients (8 men, 8 women; age range, 79 to 92 years; mean age, 84.8 years) treated with 3 consecutive monthly intravitreal injections of ranibizumab (0.5 mg/0.05 mL) and PDT and followed up for at least 12 months. PDT was applied 1 or 2 days after the initial injection. Retreatment was performed as a combined therapy of a single intravitreal ranibizumab injection and PDT. RESULTS The mean best-corrected visual acuity (BCVA) levels significantly improved from 0.24 at baseline to 0.43 at 12 months (P < .001). The mean improvement in BCVA at 12 months from baseline was 2.51 lines. The BCVA at 12 months improved in 10 eyes (improved by 3 lines or more) and was stable (defined as a loss of less than 3 lines of vision) in 10 eyes. No patient had a decrease in the BCVA of 3 lines or more during any 12 months. The central retinal thickness decreased significantly from 444 μm at baseline to 143 μm at 12 months (P < .0001). Complete occlusion of the retinal-retinal anastomosis was achieved in 17 of the 19 eyes at 12 months. The mean numbers of PDT treatments and injections during 12 months, including the treatments in the initial regimen, were 1.8 and 3.8, respectively. No complications or systemic adverse events developed. CONCLUSIONS Combined intravitreal ranibizumab and PDT for patients with retinal angiomatous proliferation effectively maintained or improved visual acuity and reduced the exudation without adverse events.

Abstract
BACKGROUND The purpose of this work was to compare the efficacy of photodynamic therapy (PDT) with or without posterior subtenon injections of triamcinolone acetonide (STA) or intravitreal injections of ranibizumab (IVR) for retinal angiomatous proliferation (RAP). METHODS Thirty-seven eyes from 33 consecutive patients with RAP were treated by PDT monotherapy (Group 1), PDT combined with STA (Group 2), or PDT combined with IVR (Group 3). The best-corrected visual acuity, greatest linear dimension, central retinal thickness, and number of treatments were compared among the three groups. RESULTS The change in mean best-corrected visual acuity (logMAR) at month 3, 6, and 12 after the initial treatment was better in Group 2 (-0.13, -0.23, and -0.21, respectively) and Group 3 (-0.018, 0.0028, and -0.0067, respectively) than in Group 1 (0.13, 0.19, and 0.23, respectively); Group 1 versus Group 2 was statistically significant (P = 0.018). The mean central retinal thickness was reduced from baseline in all groups, but the reduction amplitude was significantly greater in Group 2 than in Group 1 and Group 3. The mean number of treatments was significantly lower in Group 2 (1.1 ± 0.4) and Group 3 (1.5 ± 0.5) than in Group 1 (2.9 ± 0.9) in the 12 months after the initial treatment. CONCLUSION Treatment with STA + PDT may be an effective therapy for RAP lesions over 12 months of follow-up.

Abstract
PURPOSE The purpose of this study was to present a case of a retinal angiomatous proliferation (RAP) treated with epimacular brachytherapy that was refractory to continued ranibizumab therapy. PATIENTS An interventional case report of an 89-year-old woman with angiographically confirmed RAP had shown a poor response to 8 anti-vascular endothelial growth factor (anti-vascular endothelial growth factor) retreatment injections over a 10-month period. METHODS The patient underwent pars plana vitrectomy combined with beta irradiation of the RAP lesion using a Strontium-90 applicator (NeoVista). The device was positioned over the lesion to deliver 24 gray over 4.5 minutes. Early Treatment Diabetic Retinopathy Study best-corrected visual acuity with full refraction was undertaken monthly by trial-certified examiners, independent of the operating surgeon. The main outcome measures were Early Treatment Diabetic Retinopathy Study best-corrected visual acuity, central retinal thickness measured by optical coherence tomography, and the number of anti-vascular endothelial growth factor retreatments. RESULTS Preoperative best-corrected visual acuity was 53 letters (20/80), improving to 69 letters (20/50) at 12 months and 71 letters (20/40) at 21 months. Only one ranibizumab retreatment was required, at Month 2. Optical coherence tomography central retinal thickness reduced from 312 μm to 224 μm with a return of the normal foveal contour. There was full regression of the RAP lesion on clinical examination, with a reduction in lesion activity demonstrated by fundus fluorescein angiography. CONCLUSION This is the first reported case of RAP treated with epimacular brachytherapy, with encouraging results. Epimacular brachytherapy may be a new treatment option for refractory RAP lesions requiring frequent intravitreal ranibizumab, but further studies are needed.

Aqueous humor levels of vascular endothelial growth factor before and after intravitreal bevacizumab in type 3 versus type 1 and 2 neovascularization. A prospective, case-control study. Am J Ophthalmol 2012; 153:155-61.e2.

Abstract
PURPOSE To determine the aqueous levels of vascular endothelial growth factor (VEGF) in patients with type 3 neovascularization (NV) secondary to age-related macular degeneration (AMD) and to compare the levels of those with type 1 and 2 NV secondary to AMD before and after administration of intravitreal bevacizumab (IVB). DESIGN Prospective, case-control study. METHODS Aqueous samples were collected from 29 eyes of 29 patients with untreated wet AMD at baseline (day of the first IVB), month 1 (day of the second IVB), and month 2 (day of the third IVB). Among them, 10 eyes presented with type 1, 9 with type 2, and 10 with type 3 NV. A group of 14 aqueous samples from 14 patients who underwent cataract surgery without other ocular or systemic disease comprised the controls. Main outcome measures were concentration of VEGF at baseline and after IVB in the 3 NV groups; secondary outcome measures included best-corrected visual acuity (BCVA) and central macular thickness (CMT) changes after IVB. Levels of VEGF were determined by commercially available enzyme-linked immunosorbent assay kits. RESULTS VEGF concentrations in aqueous humor at baseline were higher in patients with type 3 NV when compared to controls (P = .0001) and type 1 and 2 NV patients (P = .002 and P = .0001 respectively). At month 1, levels of VEGF were significantly reduced compared to baseline (P < .05) and significantly lower compared to the controls (P < .005) in each NV group. These low levels were maintained at the 2-month interval. BCVA significantly improved in type 1 and 2 NV groups (P < .05). CMT significantly reduced in each NV group compared to baseline (P < .05). CONCLUSION In eyes with untreated wet AMD, aqueous levels of VEGF are significantly higher in type 3 NV than in type 1 or 2 NV. Regardless of the type of NV, aqueous VEGF levels significantly reduce 1 month after IVB as compared to both the baseline measurements and the values recorded in age-matched controls. These decreases are maintained at 2 months after administering a second IVB 30 days after the initial injection.

Abstract
BACKGROUND Vascularized pigment epithelial detachment (PED) in retinal angiomatous proliferation (RAP) represents a special morphological form of exudative age-related macular degeneration (ARMD) in the natural course and in the frequency of complications, such as tears in the pigment epithelium. In this study the results of inhibition of vascular endothelial growth factor (VEGF) for exudative ARMD with associated PED and RAP were examined. MATERIALS AND METHODS Functional and morphological data were retrospectively collected for 61 consecutive eyes with RAP in stages 2 and 3 over an average observation period of 108 weeks. Patients were treated with bevacizumab (n=15), ranibizumab (n=29) and pegabtanib (n=17) according to the recommendations of the German Society of Ophthalmology (DOG) and the German Retina Society (RG). After an initial treatment cycle of 3 injections every 4 weeks (6 weeks for pegabtanib), best corrected visual acuity (BCVA), fluorescence angiography (FAG), indocyanine green angiography (ICG-A) and optical coherence tomography (OCT) were evaluated every 12 weeks. RESULTS The mean visual acuity was 0.8 logMAR before therapy and 0.77 logMAR after therapy so that the average difference to the original acuity was -0.03 logMAR after 12 weeks and 0.00 logMAR after 48 weeks. The central retinal thickness measured by OCT decreased on average by 81.2 µm after the first cycle of injections and by -68.4 µm after 1 year. The maximum depth of PED could be reduced on average by 1 unit and after 1 year by 1.55 units. Better functional and morphological results were obtained by therapy with ranibizumab and avastin compared to pegabtanib (p=0.03). An RIP occurred in 9.8% of the patients (n=6) on average after 16 weeks. CONCLUSIONS The morphological functional results can be improved in the early months using the therapy strategy presently recommended in Germany. However, in later stages there was a significant worsening of the functional results. Modification of the treatment strategy with respect to close surveillance and possibly early stage repeat treatment would seem advisable.
