Purpose: This article describes the clinical and multimodal imaging characteristics of subthreshold exudative choroidal neovascularization (CNV) associated with age-related macular degeneration (AMD). Methods: Among 3773 patients with AMD, 8 eyes (6 patients) were identified with the clinical phenotype of interest. Dilated fundus examinations, color fundus photography, fluorescein angiography (FA), indocyanine green angiography (ICGA), optical coherence tomography (OCT), and OCT angiography (OCTA) were performed. Results: OCT typically showed a moderately reflective irregular pigment epithelial detachment with overlying subretinal fluid (SRF). Traditional FA did not show leakage and ICGA showed no definitive neovascular network or hot spots. However, OCTA clearly demonstrated a CNV within the pigment epithelial detachment. The majority of our cases (7 of 8) did not receive antivascular endothelial growth factor (anti-VEGF) injections, and visual acuity remained stable over the available follow-up period of 1 to 10 years. Conclusions: CNV is often associated with SRF and vision loss in AMD, usually requiring frequent anti-VEGF injections. OCTA allowed us to better identify CNV not readily detected on FA and ICGA. Although some have suggested early clinical intervention with anti-VEGF injections in any case with fluid and confirmed CNV on OCTA, we describe a subset of AMD patients with SRF who may be better managed by observation. These cases may represent a more indolent, mature, and stable vascular network.

Purpose: To assess intra- and subretinal fluid during the loading phase with intravitreal ranibizumab in exudative age-related macular degeneration and to quantify the accuracy of crosshair scan spectral-domain optical coherence tomography with regard to retinal fluid. Methods: This is a retrospective study of 31 treatment-naive patients who received 3 monthly intravitreal ranibizumab injections. Visual acuity and the presence of retinal fluid were assessed at each visit using volume and crosshair scan protocols. Results: Visual acuity improved and central retinal thickness decreased significantly during the loading phase. However, retinal fluid persisted in two thirds of the patients. The accuracy of the crosshair scan to detect fluid was 93%. Conclusions: A substantial proportion of eyes had persistent fluid after 3 months of ranibizumab injections. However, visual improvement was independent of residual fluid. Message: Crosshair scans detect relevant collections of retinal fluid accurately and may be sufficient in daily clinical practice.

Abstract Background To present a case report of a patient with a mixed choroidal neovascular membrane (CNV) with an asymmetric response to ranibizumab diagnosed on optical coherence tomography angiography (OCTa). Case presentation A 61-year-old male was referred to our department in September 2017 due to decreased vision in his left eye. Best-corrected visual acuity (BCVA) was 43 Early Treatment Diabetic Retinopathy Study (ETDRS) letters in the left eye. Macular edema was present in the left eye, and a mixed CNV was identified on the OCTa. Therapy with intravitreal ranibizumab was commenced. After 5 ranibizumab injections, the BCVA was 42 ETDRS letters, and considerable intraretinal edema was still present. OCTa showed a resolution of the type 2 lesion of the mixed CNV; however, the type 1 lesion had continued to grow. The patient was then switched to intravitreal aflibercept. After 3 monthly aflibercept injections, the BCVA improved to 53 ETDRS letters, and a reduction of the edema was observed on the optical coherence tomography (OCT). OCTa showed a decrease in both the area and vessel density in the type 1 lesion of the CNV. Therapy with aflibercept was continued; however, while the intraretinal edema continued to improve, atrophy developed in the macula and the BCVA worsened to 43 ETDRS letters. Conclusions Ranibizumab nonresponse in a neovascular age-related macular degeneration is not uncommon. However, to our knowledge, this is the first described case of an asymmetric response to ranibizumab in a mixed CNV. While the type 2 lesion of the CNV reacted swiftly to the ranibizumab therapy, the type 1 lesion continued to grow. As with some other cases of ranibizumab resistance, switching to aflibercept proved effective.
