BACKGROUND: To compare the 12-month outcomes of intravitreal ranibizumab (IVR) between two angiographic subtypes of polypoidal choroidal vasculopathy (PCV). METHODS: This is a retrospective cohort study of 38 treatment-naïve PCV cases. Three consecutive IVR and retreatments as needed were performed. Subsequently, the PCV cases were classified into two phenotypes (18 type 1 and 20 type 2) according to the status of branching vascular network. The best-corrected visual acuity (BCVA) was evaluated in each PCV subtype up to 12 months after the initial IVR...

Choroidal neovascularisation (CNV) in the context of exsudative age-related macular degeneration (nAMD) can be divided into type 1 (occult) and type 2 (classical) membranes. Retinal angiomatous proliferation (RAP) or polypoidal choroidal vasculopathy (PCV) are "rare subtypes" of chorioretinal neovascularisation and are distinguished by their distinct morphology and the sometimes worse response to therapy. Chorioretinal anastomosis, severe exsudates with serosanguinous pigment epithelial detachment and, in PCV, orange-red lesions in the papillomacular bundle can be diagnostic...

Though anti-vascular endothelial growth factor therapy has become the standard treatment for exudative age-related macular degeneration (AMD), retreatment after the initial loading injection is inevitable in most eyes with residual or recurrent exudative changes. In the present study, we studied 140 treatment naïve eyes with typical neovascular AMD (n = 71) or polypoidal choroidal vasculopathy (PCV) (n = 69) and investigated the incidence and risk factors of retreatment after 3-monthly intravitreal aflibercept injection for exudative AMD during the 12-month period...

We report a case of a Caucasian female who developed active polypoidal choroidal vasculopathy (PCV) at the edge of a stable choroidal nevus and was successfully treated with verteporfin photodynamic therapy. No active polyp was detectable on indocyanine green angiography 2 years after treatment, and good vision was maintained. Indocyanine green angiography is a useful investigation to diagnose PCV and may be underutilized. Unlike treatment of choroidal neovascularization secondary to choroidal nevus, management of PCV secondary to nevus may not require intravitreal anti-vascular endothelial growth factor therapy...

Retinitis Pigmentosa (RP) has been reported to be associated with retinal hemangioma, retinal angiomatous proliferation, polypoidal choroidal vasculopathy and vasoproliferative tumours. However there is no previous report of choroidal nevus in an eye with RP. We describe such a case in which the eye with RP had a choroidal nevus at the macula. The coexistence of these two entities in the same eye emphasizes the need of careful examination of patients with RP. The presence of choroidal nevus warrants additional investigations such as B scan ultrasonography and a close follow-up to pick up changes in the nevus size and morphology...

Acute angle closure glaucoma (ACG) in the setting of polypoidal choroidal vasculopathy (PCV) is a catastrophic complication that has been documented infrequently in literature. Ours is the second only report that describes hemorrhagic choroidal detachment as an event leading to acute angle closure glaucoma in PCV patients and the first one to describe the use of diode cyclophotocoagulation (CPC) for this condition. The purpose of this article is to familiarize readers with this entity that has an extremely dismal visual prognosis...
