Choroidal Vasculopathy

Polypoidal choroidal vasculopathy (PCV) is a subtype of neovascular age-related macular degeneration characterised by an abnormal branching vascular network with aneurysmal polypoidal choroidal vascular lesions. PCV is more prevalent in Asian populations than in Caucasians, which may explain its underdiagnosis in Western countries. Evidence regarding the efficacy of different anti-vascular endothelial growth factor (anti-VEGF) agents on PCV is scarce, with most of these studies being conducted in Asian treatment-naïve patients. Ranibizumab was the first anti-VEGF agent to demonstrate the superiority of a combination of photodynamic therapy (PDT) and anti-VEGF over PDT or anti-VEGF monotherapy for inducing polyp regression in Asian patients with PCV. The efficacy of other anti-VEGF agents has been less studied. Resistance to ranibizumab has been described. Aflibercept offers another mechanism of targeting choroidal neovascular lesions. A 75-year-old Caucasian woman presenting to our office was diagnosed with PCV using indocyanine green angiography. Combination therapy with a loading dose of 0.5 mg intravitreal ranibizumab followed by PDT at standard fluence at month 4 and a fourth dose of ranibizumab at month 5 yielded no visual or anatomic outcomes. Treatment was switched to intravitreal aflibercept at month 6 (3 monthly loading doses of 2.0 mg) followed by half-fluence PDT (month 9). Optical coherence tomography revealed remission of the anatomic lesions. Right-eye visual acuity increased to 0.6. Aflibercept injections were administered bimonthly afterwards. Follow-up during 1 year has shown functional and anatomic stability.

Choroidal Vasculopathy

Polypoidal choroidal vasculopathy (PCV) is a rare subtype of neovascular age-related macular degeneration (AMD), its specific features are abnormal branching vascular network with aneurysmal dilatations (polyps), it can be diagnosed in indocyanine green angiography. PCV differs from typical AMD by some ophthalmoscopic manifestations, multimodal imaging data as angiography, OCT with the ability to visualize the choroid, OCT-angiography and expression of VEGF. Despite the different response to antiangiogenic therapy, the presence of pathological neovascularization requires anti-VEGF treatment for both AMD types. In this review, we summarize the latest literature data on the treatment of polyphoidal choroidal vasculopathy: anti-VEGF monotherapy, photodynamic monotherapy, and their combinations. Special attention is paid to the results of multicenter randomized clinical trials with a large number of patients evaluating efficacy of Ranibizumab and Aflibercept (EVEREST 2 and PLANET). The short-term and long-term results of treatment are presented, taking into account the dosing regimens, the number of required injections and the requirement for a combination of anti-VEGF monotherapy with photodynamic therapy. The results of randomized clinical trial are providing high level evidence to guide clinical specialists in choosing the most appropriate therapy for PCV.

Purpose: To compare the response to ranibizumab between patients with typical neovascular age-related macular degeneration (tAMD) and those with polypoidal choroidal vasculopathy (PCV), and to determine the predictors for the outcomes. Methods: Fifty-nine eyes from 59 consecutive patients (tAMD: 27 eyes, PCV: 32 eyes) were treated with three monthly ranibizumab injections followed by as-needed retreatment. Best-corrected visual acuity (BCVA) and morphological parameters were evaluated over 24 months of follow-up. Results: The mean BCVA in tAMD and PCV patients was significantly improved at 3 months (-0.22 and -0.09 logMAR units, respectively). The improvement in BCVA was sustained up to 24 months in tAMD (p = 0.01) but not in PCV patients. The significant predictor for good response to ranibizumab in tAMD patients was the improvement of BCVA at 3 months, whereas that in PCV patients was the anatomical resolution at 3 months. Conclusions: Ranibizumab is an effective therapy for tAMD and PCV over 24 months. The predictors for good outcome might be different between tAMD and PCV.

Choroidal Vasculopathy

Polypoidal choroidal vasculopathy (PCV) is one of the choroidal neovascularization forms, being a subtype of neovascular age-related macular degeneration (nAMD). These two conditions share many characteristics, while PCV has some distinctive features with aneurysmal dilatations (polyps) at the end of abnormal branching vascular network being the most specific of them. Low documented incidence of PCV in European population (up to 13%) may be related to the absence of indocyanin-green angiography (ICG) the only reliable method for PCV diagnosis confirmation in routine clinical practice. In that regard, there should be a universal method of treatment suitable for any patient with nAMD irrespectively of whether he or she has PCV. To date, there is no common approach to PCV treatment anti-VEGF therapy, photodynamic therapy (PDT), and combination of these methods are used in clinical practice. Key diagnostic criteria helping to suspect the presence of PCV without ICG as well as results of clinical trials aimed at assessing effectiveness of different anti-VEGF agents as monotherapy or in combination with PDT are described in this article.
