Purpose: To describe a case of primary vitreous retinal lymphoma (PVRL) complicated with choroidal neovascularization (CNV) and presented with severe macular edema (ME). Case description: A 52-year-old female patient was diagnosed with bilateral PVRL. Optical coherence tomography (OCT) showed severe macular edema (ME) and subretinal hyperreflective material in the left eye at the first visit. No sign of choroidal neovascularization (CNV) was found with fundus fluorescein angiography (FFA) or indocyanine green angiography (ICGA). The ME was resolved after standard intraocular chemotherapy, while the subretinal hyperreflective material remained stable. Optical coherence tomography angiography (OCTA) was performed 2 years after chemotherapy. OCTA revealed a well-circumscribed CNV network in the subretinal hyperreflective material. Conclusion: It is a rare occurrence that CNV and ME developed in this PVRL patient. The presence of ME is not an exclusion criterion for PVRL. This case should also raise awareness of the importance of OCTA as a method for monitoring intraocular lymphoma during follow-up.

Purpose: Since its first description by Chang et al. in 1995, the diagnosis of Idiopathic retinal vasculitis, aneurysms and neuroretinitis (IRVAN) syndrome has been based on the findings of Fundus Fluorescein Angiography (FFA). Our purpose was to describe the utility of optical coherence tomography angiography (OCT-A) in its diagnosis and management. Case description: A 40-year-old female presented with bilateral blurred vision. Her best corrected visual acuity was at 8/10. Fundus examination revealed blurred disc margins, perivascular exudates, arterial sheaths and retinal hemorrhages bilaterally. FFA showed staining of the optic disc with dye leakage in the right eye, a punctuate hyperfluorescence of the temporosuperior artery in the left eye, bilateral vascular sheathing and capillary dropout. OCT-A showed simultaneous presence of papillary aneurysm and neovascularization of the optic nerve head in the right eye, a papillary aneurysm in the left eye and bilateral capillary non-perfusion. Our patient was diagnosed with IRVAN syndrome. Oral steroids associated with panretinal laser photocoagulation and intravitreal injection of bevacizumab in the right eye resulted in vanishing of the papillary neovascularization with no recurrence on OCT-A at 10-month follow-up. Conclusions: OCT-A is an additional tool to FFA for visualization of arterial macroaneurysms and retinal neovascularization without the interference of dye leakage. It well demarcates nonperfused areas and ensures follow-up of retinal neovascularization. Its limitations are the limited field of view and the low sensitivity in detecting arteriolar dilations. Thus, OCT-A is unable to outplace FFA but should be considered alternately with it for non-invasive follow-up of IRVAN syndrome.

Purpose: To describe the optical coherence tomography angiography characteristics of myopic patients with choroidal neovascularization secondary to pathologic myopia during ranibizumab therapy. Methods: Nineteen patients were enrolled in this prospective study (13 females, 6 males, mean age 55.25 ± 9.63 years) for a total of 20 eyes examined (14 right eyes, 6 left eyes). Images were analyzed independently by two examiners. Results: Mean follow-up was 5.75 ± 1.88 months, with a mean intravitreal injections of 1.90 ± 0.44. Mean best-corrected visual acuity at baseline was 0.39 ± 0.18 logMAR versus 0.26 ± 0.16 logMAR 6 months after treatment. The neovascular area (Z = –2.091, p = 0.037) was significantly reduced after treatment, whereas vessel density was not (Z = –1.848, p = 0.065). Moreover, the best-corrected visual acuity was increased (Z = –3.055, p = 0.002). Neovascular area was significantly correlated with best-corrected visual acuity, at both baseline and follow-up (p < 0.05). Conclusion: Our data suggest that optical coherence tomography angiography is a reproducible non-invasive examination with which to monitor changes in the neovascular area in patients with pathologic myopia treated with ranibizumab.

Abstract Background Choroidal osteoma is a benign intraocular tumor that can increase risk of developing choroidal neovascularization. The visual prognosis is influenced by the tumor location, decalcification status, overlying RPE atrophy, presence of choroidal neovascularization, persistence of subretinal fluid and occurrence of subretinal hemorrhages. Case presentation The authors present a 40-year-old woman diagnosed with choroidal osteoma of the right eye. Her best corrected visual acuity was 12/20 but decreased to 5/20 due to secondary choroidal neovascularization after 8 years follow up. Fundus examination revealed an enlarged choroidal osteoma in most margins at posterior pole with schistose hemorrhage beside macula. Optical coherence tomography angiography revealed unique features in the vascular changes of choroidal neovascularization in choroidal osteoma in the outer retinal layer and choroid capillary layers, and subretinal neovascularization. Indocyanine green fluorescence angiography showed there was hypo-fluorescence at the peripapillary with faint hyper-fluorescence at the macular, corresponding to the location on the fundus photograph. The patient received 3 injections of intravitreal ranibizumab. After 1 year follow up, her visual acuity of the right eye was 18/20 and the CNV had regressed. Conclusions We present the findings and treatment of a case of choroidal osteoma with secondary choroidal neovascularization. Optical coherence tomography angiography combined with FFA and ICGA is used to analysis the characteristics of secondary choroidal neovascularization. Optical coherence tomography angiography can reveal some unique characteristics in the vascular changes compared to fundus fluorescein angiography.

A 37-year-old Caucasian woman presented with acute decrease in central vision in her right eye and was found to have subfoveal choroidal neovascularization (CNV) due to presumed ocular histoplasmosis syndrome (POHS). Her visual acuity improved from 20/70 to 20/20 at her 6-month follow-up, after 3 consecutive monthly intravitreal bevacizumab injections were initiated at her first visit. Although no CNV activity was seen on fluorescein angiography (FA) or spectral-domain optical coherence tomography (SD-OCT) at her 2-month, 4-month, and 6-month follow-up visits, persistent flow in the CNV lesion was detected on optical coherence tomography angiography (OCTA). OCTA shows persistent vascular flow as well as changes in vascular flow in CNV lesions associated with POHS, indicating the continued presence of patent vessels and changes in these CNV lesions, even when traditional imaging of the lesion with OCT and FA indicates stability of the lesion with no disease activity. Additional cases with longitudinal follow-up are needed to assess how OCTA should be incorporated into clinical practice.

Purpose. To describe a case of a 25-year-old man with choroidal neovascularization (CNV) secondary to traumatic choroidal rupture treated with intravitreal bevacizumab and to evaluate the vascular structure of the area near the traumatic choroidal rupture. Methods. The patient underwent complete ophthalmologic evaluation, including best-corrected visual acuity (BCVA), intraocular pressure, anterior segment and funds examination, and optical coherence tomography angiography (OCTA) at baseline and on each follow-up visit. Fluorescein angiography (FA) was performed at baseline. Intravitreal bevacizumab was administered at the time of choroidal neovascular membrane diagnosis. Results. At baseline, ophthalmoscopic examination of the left eye revealed four subretinal macular hemorrhages and two choroidal ruptures located temporally to the fovea. On OCT angiograms, the choroidal rupture appeared as a hypointense break in choriocapillaris plexus. At 4-week follow-up, the OCTA disclosed a well circumscribed lesion characterized by numerous and fine anastomotic vessels. Patient received intravitreal injection of bevacizumab. At 6-week post injection, OCTA documented regression of the neovascular complex. Conclusion. Choroidal neovascularization is a common complication associated with traumatic choroidal rupture and OCTA may represent a complementary diagnostic technique to evaluate the vascular structure of the area near the traumatic choroidal rupture.

Purpose: To report a case of quiescent choroidal neovascularization (CNV) associated with choroidal nevus using optical coherence tomography angiography (OCTA) during 5 years follow-up. Methods: Observational case report. Results: A 53-year old woman was referred our department with diagnosis of choroidal nevus. At 1 year follow-up, fundus autofluorescence revealed hyper/hypoautofluorescent area, infrared image showed hyperreflective area and enhanced depth imaging OCT presented a shallow pigment epithelium detachment without exudation or hemorrhage. Fluorescein angiography and indocyanine green angiography suspected the presence of CNV. Finally, OCTA confirmed a quiescent CNV with an increased flow area of the vascular lesion without any changes in best-corrected visual acuity. At 20 months and 5 years follow-up, the CNV remained quiescent showing no clinical activity on structural SD-OCT and no changes in CNV morphology on OCTA. Conclusion: This case shows the features of quiescent CNV secondary to choroidal nevus after long-term follow-up. OCTA represents a valid imaging technique that allows to identify the CNV and to monitor its progression over time.

Purpose: To report longitudinal changes in fellow eyes of chronic central serous chorioretinopathy (CSCR) associated choroidal neovascularization (CNV) using optical coherence tomography angiography (OCTA) and determine factors affecting neovascular conversion. Methods: Medical records of patients with chronic CSCR complicated by CNV and a minimum follow up of 6 months were reviewed. OCT and OCTA features were analyzed at baseline and final follow up. Baseline factors were assessed for predictive value against presence of CNV at follow up and conversion to exudative form. Results: Twenty-six subjects (26 CNV and 26 fellow eyes) were included in the study and followed up for a mean period of 26 ± 17 months. Nine eyes had CNV network in fellow eye at baseline, out of which three (33%) had a conversion to exudative CNV. Among the remaining 17 eyes, one eye developed a new network during a period of 44 months. An increase in the size of network was seen from 0.886 ± 0.945 mm2 at baseline to 1.326 ± 1.263 mm2 at follow up. Baseline choroidal thickness at sub-fovea was 345.4 ± 74.9 microns in eyes having network at last visit, compared to 440.1 ± 73.7 microns in eyes having no network.( p < 0.001) None of the baseline variables were found to be significantly associated with conversion to exudative form or presence of CNV on follow up in multivariate analysis. Conclusion: A conversion rate to exudative form was seen in 33% of fellow eyes with CNV. Relatively thinner choroid at baseline was associated with exudative conversion during follow up.
