Purpose. To investigate the incidence and timing of prechoroidal cleft development and its association with visual prognosis in type 3 neovascularization. Methods. This retrospective study included 166 eyes that were diagnosed with type 3 neovascularization. All eyes were treated with antivascular endothelial growth factor therapy. The incidence and timing of prechoroidal cleft development were evaluated. Best-corrected visual acuity (BCVA) at diagnosis and at final follow-up was compared between eyes with (cleft group) and without (no-cleft group) prechoroidal cleft. The incidence of retinal pigment epithelium (RPE) tear and subretinal hemorrhage was also compared between the two groups. Results. During the mean 39.7 ± 18.5 months of follow-up, prechoroidal cleft developed in 37 eyes (22.3%) at an average of 14.6 ± 10.4 months. The BCVA at final follow-up was significantly worse in the cleft group than in the no-cleft group (P=0.024), whereas the difference was not significant at diagnosis (P=0.969). The incidence of RPE tear (P=0.002) and subretinal hemorrhage (P<0.001) was significantly higher in the cleft group. Conclusions. Prechoroidal cleft is a frequently observed finding during the treatment course of type 3 neovascularization. Eyes with prechoroidal cleft are at high risk of RPE tear or subretinal hemorrhage and subsequently associated with poor prognosis.

PurposePeripheral exudative haemorrhagic chorioretinopathy (PEHCR) is a rare disorder that is often misdiagnosed. The aim of this study was to better characterise PEHCR and to assess treatment options.Material and methodsRetrospective multicentric chart review.ResultsOf 84 eyes (69 patients) with PEHCR referred between 2005 and 2017, the most common referral diagnosis was choroidal melanoma (41.3%). Bilateral involvement was found in 21.7% of cases. Haemorrhagic retinal pigment epithelium detachment was the most common peripheral lesion (53.6%). Maculopathy was associated with peripheral lesions in 65.8% of cases. PEHCR lesions were mostly heterogeneous (58.8%) on B-scan ultrasonography. Choroidal neovascularisation was found in 10 eyes (26.3%) out of 38 eyes that underwent fluorescein angiography. Polyps were observed in 14 eyes (58.3%) out of 24 eyes that underwent indocyanine green angiography. Fifty-one eyes were treated (62.2%). Intravitreal injections (IVTI) of antivascular endothelial growth factor (VEGF) were the most used treatment (36.6%) before laser photocoagulation, photodynamic therapy, vitrectomy and cryotherapy. Only vitrectomy improved visual acuity. Most lesions (65.6%) regressed at the last follow-up visit.ConclusionIn case of PEHCR, multimodal imaging is useful to avoid misdiagnosis, to characterise PEHCR lesions and to guide treatment strategies. Regression of PEHCR lesions was observed in two-thirds of the patients. Vitrectomy improved visual acuity. More than a third of patients underwent anti-VEGF IVTI. Further studies are needed to assess IVTI’s efficacy.

Purpose: To assess the visual prognostic factors of retinal pigment epithelium (RPE) tears and describe their clinical features. Methods: The medical records of treatment-naive neovascular age-related macular degeneration patients who received intravitreal anti-vascular endothelial growth factor (VEGF) injections were retrospectively reviewed. Results: The incidence of RPE tears was 1.36% (10 out of 733 eyes). The type of anti-VEGF agent administered did not affect the incidence (p = 0.985). The median best-corrected visual acuity (BCVA) of 10 patients decreased after an RPE tear (0.4 to 0.6 logMAR); however, subsequent injections restored the BCVA to a level similar to that before the RPE tear (0.4 logMAR, p = 0.436). Central macular thickness improved significantly during the study (794.4 to 491.9 μm, p = 0.013). The final BCVA was positively correlated with the BCVA before and immediately after the RPE tear (p = 0.025 and 0.002, respectively) and was weakly correlated with foveal involvement of the RPE tear (p = 0.061). Conclusion: The incidence of RPE tears did not differ according to the type of anti-VEGF agent. The final BCVA was proportional to the BCVA before and after RPE tears. Continuous treatment with anti-VEGF after the occurrence of RPE tears can benefit the final visual acuity and macular anatomy.

A 76-year-old male presented with a small hyperreflective density in the outer nuclear layer with subtle retinal pigment epithelium (RPE) elevation and few intraretinal cysts on spectral-domain optical coherence tomography (SD-OCT). Optical coherence tomography angiography (OCTA) confirmed the presence of a tuft-shaped intraretinal neovascular lesion. SD-OCT performed 2 months before showed a smaller RPE elevation at the same location without intraretinal fluid. A 79-year-old male presented with a small hyperreflective density in the outer retina surrounded by scant intraretinal fluid on SD-OCT and a bright vessel on OCTA, suggesting early-stage type 3 neovascularization. SD-OCT performed 2 months before showed a smaller hyperreflectivity at the same location, without intraretinal fluid. An 84-year-old female presented with hyperreflective foci in the outer retina overlying a serous pigment epithelium detachment (PED) with focal RPE disruption on SD-OCT. SD-OCT performed 2 months before showed the same hyperreflective lesion associated with a shallower PED. No neovascular lesions were found on OCTA after six injections of bevacizumab. To conclude, careful evaluation of SD-OCT allows for early detection of type 3 neovascularization at a pre-exudative stage. OCTA may be useful in confirming the presence of intraretinal neovascular lesion and monitoring response to anti-vascular endothelial growth factor agents.

Purpose. To determine whether fluorescein leakage within subretinal hemorrhage is definitely suggestive of choroidal neovascularization (CNV) by multimodal imaging including optical coherence tomography angiography (OCTA). Methods. Twenty-five consecutive highly myopic patients (25 eyes) with fluorescein leakage within subretinal hemorrhage detected within 1 month were prospectively included. All patients underwent OCTA and spectral-domain optical coherence tomography (SD-OCT). The OCTA and SD-OCT findings at the site of fluorescein leakage were analyzed. In cases of a doubtful diagnosis, indocyanine green angiography (ICGA) was also performed to differentiate myopic CNV from lacquer crack if necessary; all patients were followed up by SD-OCT and/or OCTA for at least 2 weeks. Results. In terms of the site of fluorescein leakage, OCTA revealed an abnormal vascular network in the outer retina and a choriocapillaris slab in 22 out of 25 eyes (88%), which were confirmed to be CNV. However, no high-flow signal was observed in 3 of 25 eyes (12%). In these 3 cases, SD-OCT showed a focal rupture of the retinal pigment epithelium-Bruch’s membrane-choriocapillaris (RPE-BM-CC) complex and a columnar hyperreflective signal of blood originating from defects with a volcanic geyser-like appearance, and no exudative signs were detected. Notably, all ruptures of the RPE-BM-CC complex were located exactly at lacquer crack sites. Moreover, with the absorption of subretinal hemorrhage, ruptures of the RPE-BM-CC complex spontaneously resolved without any intervention. Considering the multimodal imaging appearance and follow-up outcomes, these 3 eyes were eventually diagnosed as simple bleeding associated with lacquer cracks. Conclusions. Dye leakage within recent subretinal hemorrhage on FA could be caused by new-onset lacquer cracks in pathologic myopia. Multimodal imaging including OCTA is helpful to differentiate lacquer cracks from myopic CNV.

Purpose: To report two cases of retinal pigment epithelium (RPE) tears following treatment with aflibercept of exudative macula degeneration associated with pigment epithelial detachment (PED) tachyphylactic to antivascular endothelial growth factor (VEGF) A agents such as bevacizumab or ranibizumab.Methods: Retrospective case series of patients with exudative macular degeneration with PED who were managed with anti-VEGF A agents that developed RPE tear following the first aflibercept injection. The patients were followed with optical coherence tomography and fluorescein angiography.Results: In our two cases, RPE tear developed after being switched from bevacizumab or ranibizumab to treatment with aflibercept. Both cases were rescued with monthly ranibizumab injections. In each case vision and macular edema improved with continued treatment.Conclusion: RPE tears may occur following injection with aflibercept for treatment of exudative AMD tachyphylactic to bevacizumab or ranibizumab. Continued anti-VEGF treatment can be effective rescue therapy.

PurposeTo investigate optical coherence tomography angiography (OCT-A) findings in recurrent type 3 macular neovascularisation (MNV).MethodsIn this retrospective cohort study, consecutive patients with type 3 MNV secondary to age-related macular degeneration underwent OCT-A at three different time points: baseline, after anti-vascular endothelial growth factor treatment with complete resolution of the exudative signs (ie, non-exudative stage) and at the recurrence of exudation (ie, recurrence stage). Demographics and clinical findings were analysed, including OCT-A features of type 3 MNV recurrence.ResultsTwelve eyes (12 patients, mean age 78±7 years) were included. Using OCT-A, at baseline all type 3 MNVs showed the presence of detectable flow downgrowing from the deep vascular complex (DVC) to the retinal pigment epithelium (RPE)/sub-RPE space. 6/12 eyes (50%) showed anomalous flow under the RPE, while the other 6 eyes showed flow reaching the RPE without anomalous flow in the sub-RPE space. At the non-exudative stage (after treatment), BCVA and CMT significantly improved (p=0.004 and p=0.036), and flow inside the retinal lesions reduced; interestingly the connection to the RPE/sub-RPE space regressed. At the time of recurrence, all type 3 MNVs showed the presence of intra/sub-retinal exudation with restoration of the flow deepening from the DVC to the RPE/sub-RPE space.ConclusionsDetectable flow deepening from the DVC to the RPE/sub-RPE space using OCT-A is mandatory to have a new exudation secondary to recurrent type 3 MNV. Early detection of type 3 MNV recurrence by OCT-A characterisation may prompt retreatment and potentially prevent progression to late stages of the disease.

Retrospective Multicenter Study

Purpose. To evaluate the response of intravitreal aflibercept injection (IAI) in eyes with detachment of retinal pigment epithelium (DEP) secondary to nAMD refractory to monthly ranibizumab. Patients and Methods. This is a retrospective, multicenter study. All patients received 3 IAI then treated as needed every 4 weeks for 12 months. During the second year, the eyes were treated with a treat- and-extend regimen. Results. Forty-four eyes were included. Best-corrected visual acuity improved significantly after the loading phase (3.1 ± 6.4 letters) and at 6 months (2.8 ± 6.4 letters), but change was not significant at 1 year and 2 years. The height of the DEP was significantly decreased at 3 months and 6 months, but the difference did not reach statistical difference at 1 and 2 years. Rate of eyes with complete resolution of exudation was 59% after the loading phase and 34.3% at 2 years. Mean interval of anti-VEGF injection was extended from 31 ± 2.6 days to 61 ± 5 days after conversion. Conclusions. Aflibercept intravitreal injection in patients with fibrovascular DEP due to nAMD who respond poorly to monthly ranibizumab led to short-term functional and anatomical improvement. Reduction of intravitreal injection frequency was obtained until 2 years of follow-up.

Purpose. To describe the case of spontaneous resolution of epiretinal membrane in a patient with Combined Hamartoma of the Retina and Retinal Pigment Epithelium (CHR-RPE), in the clinical context of Gorlin Syndrome (GS).Methods. Observational case report of a 12-year-old female patient is presented. The diagnosis of CHRRPE was made by OCT and fundus examination, which showed a mound of disorganized tissue originating from retina and retinal pigment epithelium. Epiretinal membrane (EM) was also detected. Genetic study was performed to confirm the diagnosis of GS.Results. The patient was observed for 39 months, showing spontaneous resolution of the traction caused by the EM and improvement in visual acuity (VA), which was 20/80 at initial presentation, rising to 20/40 after follow-up period.Conclusions. The presence of EM in CHR-REP is a cause of reduction of visual acuity. Management of this condition is controversial; however, we would like to highlight that spontaneous resolution of the traction caused by EM is possible, resulting in recovery of VA.

AimTo characterise macular neovascularisation (MNV) developing in eyes affected by geographic atrophy (GA).MethodsIn this multicentric longitudinal study involving three retina referral centres, patients previously affected by GA who developed an active MNV were included. Patients were investigated using structural optical coherence tomography (OCT), fundus autofluorescence, OCT-angiography and dye angiographies. Patients were treated with ProReNata antivascular endothelial growth factor (VEGF) injections and were revaluated after treatment.ResultsAmong 512 patients previously diagnosed with GA, 40 eyes of 40 patients (mean age 80.8±7.9 years, mean GA area 8.73±7.39 mm2) presented with treatment-naïve exudative MNV (accounting for an estimated prevalence of 7.81%; 5.49 to 10.13, 95% CIs) and thus were included in the analysis. 67.5% of MNVs were classified as type 2 MNV, 25% as type 1, 2.5% as type 3 and 5% as mixed phenotype. In 92.5% of cases, active MNV in GA showed subretinal hyperreflective material with or without evidence of subretinal/intraretinal hyporeflective exudation. During a mean follow-up of 28±25 months, patients were treated with 6.6±6.3 anti-VEGF injections, with 2.9±1.4 injections in the first year of treatment. No patient developed GA enlargement in the area of MNV.ConclusionsMNVs in GA showed different features and therapeutic response in comparison to previously reported features of MNV in age-related macular degeneration (AMD) without GA. For these reasons, the combined phenotype (ie, GA with neovascular AMD) should be considered as a distinct entity in the research and clinical setting.
