RESUMO
ABSTRACT Objective: To evaluate the epidemiological, clinical, and imaging profile of lesions that mimic choroidal melanoma. Methods: Retrospective study of medical records of suspected choroidal melanoma lesions referred to the Ocular Oncology Service from the Universidade Federal de São Paulo, from 2014 to 2020. Demographic data, clinical history, and exams were evaluated. Results: A total of 104 patients (mean age: 65.57 ± 13.18; 49.04% female) were referred to our service with suspected choroidal melanoma. Of these, 32 (30.77%) were classified as pseudomelanoma, while 72 (69.23%) had a confirmed diagnosis of choroidal melanoma. Pseudomelanoma cases manifested in older individuals (p < 0.001), with smaller lesions in height (p < 0.001), anteroposterior diameter (p = 0.008), and lateral diameter (p = 0.003) on ultrasound. Pseudomelanoma cases were associated with higher frequencies of vitreous hemorrhage (p = 0.014) and lower rates of the presence of a mass (p = 0.001) and retinal detachment (p < 0.001). The main diagnoses of pseudomelanoma cases were choroidal nevus (40.63%), subretinal hemorrhage (18.75%) and choroidal neovascular membrane (18.75%). Conclusion: Almost one third of the cases referred with suspected choroidal melanoma were pseudomelanomas, which demonstrates that there is still a considerable path to improve the ability of general ophthalmologists to clinically discriminate melanoma from other conditions that can mimic it.
RESUMO Objetivo: Avaliar a frequência e o perfil epidemiológico, clínico e de imagem das lesões que simulam o melanoma de coroide. Métodos: Trata-se de estudo de revisão retrospectiva de prontuários de suspeita de lesões de melanoma de coroide de 2014 a 2020 no Setor de Oncologia Ocular da Universidade Federal de São Paulo. Foram avaliados dados demográficos, dados clínicos e exames complementares. Resultados: Um total de 104 pacientes (média de idade: 65,57 ± 13,18; 49,04% do sexo feminino) foram encaminhados ao nosso serviço com suspeita de melanoma de coroide. Destes, 32 (30,77%) foram classificados como pseudomelanoma, enquanto 72 (69,23%) tiveram diagnóstico confirmado de melanoma de coroide. Os casos de pseudomelanoma manifestaram-se em indivíduos mais velhos (p < 0,001) e apresentaram lesões menores em altura (p < 0,001), diâmetro anteroposterior (p = 0,008) e diâmetro lateral (p = 0,003) na ultrassonografia. Os casos de pseudomelanoma estão associados a maiores frequências de hemorragia vítrea (p = 0,014) e menores taxas de presença de massa (p = 0,001) e descolamento de retina (p < 0,001). Os principais diagnósticos dos casos de pseudomelanoma foram nevo (40,63%), hemorragia sub-retiniana (18,75%) e membrana neovascular coroidal (18,75%). Conclusão: Quase um terço dos casos encaminhados com suspeita de melanoma de coroide foram pseudomelanomas, o que demonstra que ainda há um caminho considerável para melhorar a habilidade do oftalmologista geral em discriminar clinicamente o melanoma de outras condições que o simulam.

Las membranas neovasculares coroidea representan el crecimiento de nuevos vasos sanguíneos originados de la coriocapilar hacia el epitelio pigmentario de la retina o el espacio subretinal por una disrupción de la membrana de Bruch ocasionado por la inflamación prolongada. El desarrollo de las membranas neovasculares coroidea está estrechamente conectado a la morbilidad asociada con la coroidopatía punteada interna y puede ser su primera forma de presentación. La coroidopatía punteada interna es clasificada como una de las enfermedades de los síndromes de puntos blancos evanescentes, es una enfermedad infrecuente, bilateral y de origen desconocido. Se presenta un caso clínico de un paciente al cual se le diagnostica membranas neovasculares coroidea en el curso de una coroidopatía punteada interna con una presentación atípica o previa a las lesiones de coroiditis. La coroidopatía punteada interna complicada con membranas neovasculares coroidea compromete la visión central de forma considerable en pacientes jóvenes(AU)
Choroidal neovascular membranes represent the growth of new blood vessels originating from the choriocapillaris into the retinal pigment epithelium or subretinal space due to disruption of Bruch's membrane caused by prolonged inflammation. The development of choroidal neovascular membranes is closely connected to the morbidity associated with punctate inner choroidopathy and may be its first form of manifestation. Punctate Inner choroidopathy is classified as one of the evanescent white dot syndromes diseases, is a rare, bilateral disease of unknown origin. We present a case report of a patient diagnosed with choroidal neovascular membranes while suffering from punctate inner choroidopathy with an atypical manifestation or prior to choroiditis lesions. Punctate Inner choroidopathy when complicated with choroidal neovascular membranes compromises significantly the central vision in young patients(AU)

ABSTRACT Reticular pigmentary retinal dystrophy, also known as Sjögren's reticular dystrophy, is a rare condition characterized by macular lesions with a reticular pattern, which are best seen on fluorescein angiogram. Choroidal neovascularization secondary to this type of dystrophy is even less common. This report describes a case of reticular pigmentary retinal dystrophy with vision loss due to neovascular membrane, which responded well to treatment with anti-vascular endothelial growth factor.
RESUMO A distrofia reticular pigmentar da retina, também conhecida como distrofia reticular de Sjögren, é uma doença rara, caracterizada por lesões maculares com um padrão reticular, que são mais bem visualizadas na angiografia com fluoresceína. A neovascularização de coroide secundária a este tipo de distrofia é ainda menos comum. Este relato descreve um caso de distrofia reticular pigmentar da retina, com perda de visão devido à membrana neovascular, que respondeu bem ao tratamento com fator de crescimento endotelial antivascular.

Objetivo: Determinar las características clínicas y epidemiológicas de la neovascularización coroidea en los pacientes con uveítis. Métodos: Se realizó un estudio observacional, descriptivo y transversal en pacientes con diagnóstico de neovascularización coroidea asociada a uveítis, atendidos en el Servicio de Uveítis e Inflamaciones Oculares del Instituto Cubano de Oftalmología "Ramón Pando Ferrer". Resultados: Esta entidad predominó en el sexo femenino, en edad pediátrica y en jóvenes. Se asoció con mayor frecuencia a enfermedades infecciosas, como la toxoplasmosis ocular, y un pequeño número de pacientes desarrolló membrana neovascular coroidea bilateral. Las membranas localizadas con mayor frecuencia fueron las subfoveales. Por angiografía fluoresceínica predominaron las clásicas, mientras el grosor de la membrana neovascular coroidea fue mayor que el grosor foveal central. La agudeza visual mejor corregida en la mayoría de nuestros pacientes fue menor de 85 VAR. Conclusión: La membrana neovascular coroidea asociada a las uveítis es reconocida como una complicación infrecuente, pero compromete de forma severa la visión en estos pacientes(AU)
Objective. To determine the clinical-epidemiological characteristics of choroidal neovascularization in patients with uveitis. Method. An observational, descriptive, cross-sectional study was carried out in patients with a diagnosis of choroidal neovascularization associated with uveitis, attended in the Uveitis and Ocular Inflammations Service of the Cuban Institute of Ophthalmology "Ramón Pando Ferrer". Results. This entity predominated in the female sex, in pediatric age and youth. It was more frequently associated with infectious diseases, such as ocular toxoplasmosis, and a small number of patients developed bilateral choroidal neovascular membrane. The most frequent location of the membranes were the subfoveal ones, by fluorescein angiography the predominantly classic ones and the thickness of the choroidal neovascular membrane was greater than the central foveal thickness. The best corrected visual acuity in most of our patients was less than 85 VAR. Conclusion. CNVM associated with uveitis is recognized as an uncommon complication but one that severely compromises vision in these patients(AU)

PURPOSE: To describe a case of focal choroidal excavation (FCE) complicated with Type-2 choroidal neovascularization (CNV) in a patient with angioid streaks secondary to pseudoxanthoma elasticum before and after treatment with bevacizumab. METHODS: Fundus photography, fundus autofluorescence, fluorescein angiography, indocyanine green angiography, spectral-domain optical coherence tomography (SD-OCT) and SD-OCT angiography were performed in a 60-year-old white woman with angioid streaks and bilateral FCE. Spectral domain OCT images were taken before and after three-monthly intravitreal injections of bevacizumab. Histopathological analysis of the dermis established the diagnosis of pseudoxanthoma elasticum. RESULTS: Multimodal imaging revealed bilateral FCE and CNV. Spectral domain OCT diagnosed bilateral FCE and Type-1 and Type-2 CNV in the right eye, and irregular vascular network, along macular streak, in both eyes, which were not observed on fluorescein neither on indocyanine green angiography, but only on SD-OCT angiography. Patient presented good anatomical and functional response to intravitreal injections of bevacizumab. CONCLUSION: Focal choroidal excavation is a rare condition detected mainly by SD-OCT, which may be associated with angioid streaks secondary to pseudoxanthoma elasticum and complicated by CNV. Multimodal imaging is important for diagnosis and follow-up of such patients, even in the absence of signs of CNV, and anatomical and functional response to anti-vascular endothelial growth factor therapy is good.

PURPOSE: To evaluate the 52-week safety and efficacy of intravitreal ziv-aflibercept in patients with neovascular age-related macular degeneration. METHODS: All patients received three monthly intravitreal injections of 0.05 mL of ziv-aflibercept (1.25 mg) followed by a pro re nata regimen. The best-corrected visual acuity and spectral domain optical coherence tomography were obtained at baseline and monthly. Full-field and multifocal electroretinograms were obtained at baseline and 4, 13, 26, and 52 weeks. For some full-field electroretinography parameters, we calculated the differences between baseline and 52 weeks and then compared those differences between treated and untreated fellow eyes. RESULTS: Fifteen patients were included and 14 completed the 52-week follow-up. The mean best-corrected visual acuity improved from 0.95 ± 0.41 (20/200) at baseline to 0.75 ± 0.51 (20/125) logarithm of the minimum angle of resolution at 52 weeks (P = 0.0066). The baseline central retinal thickness decreased from 478.21 ± 153.48 µm to 304.43 ± 98.59 µm (P = 0.0004) at 52 weeks. Full-field electroretinography parameters used to assess retinal toxicity after intravitreal injections (rod response and oscillatory potentials) remained unchanged during follow-up. The average multifocal electroretinography macular response in 5° showed increased N1-P1 amplitude and decreased P1 implicit time (P < 0.05). One patient presented with intraocular inflammation after the seventh intravitreal procedure. CONCLUSION: The results suggested that intravitreal ziv-aflibercept might be safe and effective for treating neovascular age-related macular degeneration. More patients and a longer follow-up are needed to confirm the long-term outcomes of intravitreal ziv-aflibercept.

PURPOSE: To evaluate retinal and choroidal changes in patients with non-granulomatous choroiditis using the multimodality imaging (MMI). METHODS: Eight eyes of four patients were analyzed. Three patients (six eyes) were diagnosed with serpiginous choroiditis (SC) and one patient (two eyes) with acute posterior multifocal placoid pigment epitheliopathy (APMPPE). The patients were imaged on the same day using the RTVue Avanti XR instrument OCT/OCTA (Optovue Inc, Fremont, CA), Heidelberg Retina Angiograph 2 FAF and FA (Heidelberg Engineering, Germany), and TRC50DXi Topcon FP (Topcon Medical Systems, Oakland, NJ). RESULTS: OCT angiography (OCTA) showed hypoperfusion in all the cases, reperfusion in choriocapillaris in two eyes after treatment and identified a choroidal neovascularization (CNV), which was not detected on the fluorescein angiography (FA). CONCLUSIONS: OCTA may be an effective noninvasive image modality to follow up these patients and may provide further information to help us to understand the pathophysiology and complications of these diseases.

The authors report a new variant of idiopathic polypoidal choroidal vasculopathy (IPCV) in middle-aged Haitian men characterized by extramacular polypoidal lesions and bilateral extensive pigmentary alterations in the posterior pole in an annular wreath-like pattern surrounding the optic nerve and macular area. Two patients were seen at Massachusetts Eye and Ear Infirmary and one at Boston University Medical Center between 2010 and 2015. All three patients were middle-aged Haitian men who exhibited bilateral features of IPCV, including subretinal hemorrhages and serosanguinous pigment epithelial detachments. Indocyanine green angiography revealed extramacular polypoidal lesions located mostly along the major vascular arcades. Extensive pigmentary alterations were evident in the posterior pole surrounding the macula and optic nerve in an annular wreath-like pattern. These cases further expand the clinical spectrum of IPCV.

PURPOSE: To determine whether angiography with swept-source (SS) optical coherence tomography (OCT) identifies subclinical type 1 neovascularization in asymptomatic eyes with intermediate age-related macular degeneration (iAMD). DESIGN: Prospective, observational, consecutive case series. PARTICIPANTS: Patients with asymptomatic iAMD in one eye and neovascular age-related macular degeneration (AMD) in their fellow eye. METHODS: The patients underwent SS OCT angiography (OCTA), fluorescein angiography (FA), and indocyanine green angiography (ICGA), and the images from these 3 angiographic techniques were compared. MAIN OUTCOME MEASURES: Identification of subclinical type 1 neovascularization with SS OCTA in asymptomatic eyes with iAMD. RESULTS: Eleven consecutive patients with iAMD in one eye and neovascular AMD in their fellow eye were imaged with FA, ICGA, and SS OCTA between August 2014 and September 2015. Clinical examination of the 11 eyes revealed drusen and pigmentary abnormalities in the central macula and no evidence of macular fluid on routine OCT imaging. Ten of the 11 eyes had no evidence of leakage on FA and 1 eye had questionable fluorescein leakage. Indocyanine green angiography revealed the presence of central macular plaques in 3 of the 11 asymptomatic eyes with iAMD, and SS OCTA revealed unambiguous type 1 neovascularization corresponding to the plaques in all 3 eyes. Optical coherence tomography angiography did not identify neovascularization in the remaining 8 eyes. CONCLUSIONS: Swept-source OCTA identified type 1 neovascularization corresponding to ICGA plaques in asymptomatic eyes with iAMD. The ability of OCTA to provide noninvasive, fast, detailed, depth-resolved identification of nonexudative neovascular lesions in eyes with iAMD suggests the need for a new classification system that distinguishes between neovascular and nonneovascular iAMD.

PURPOSE: To compare visualization of choroidal neovascularization (CNV) secondary to age-related macular degeneration (AMD) using an ultrahigh-speed swept-source (SS) optical coherence tomography angiography (OCTA) prototype vs a spectral-domain (SD) OCTA device. DESIGN: Comparative analysis of diagnostic instruments. METHODS: Patients were prospectively recruited to be imaged on SD OCT and SS OCT devices on the same day. The SD OCT device employed is the RTVue Avanti (Optovue, Inc, Fremont, California, USA), which operates at â¼840 nm wavelength and 70 000 A-scans/second. The SS OCT device used is an ultrahigh-speed long-wavelength prototype that operates at â¼1050 nm wavelength and 400 000 A-scans/second. Two observers independently measured the CNV area on OCTA en face images from the 2 devices. The nonparametric Wilcoxon signed rank test was used to compare area measurements and P values of <.05 were considered statistically significant. RESULTS: Fourteen eyes from 13 patients were enrolled. The CNV in 11 eyes (78.6%) were classified as type 1, 2 eyes (14.3%) as type 2, and 1 eye (7.1%) as mixed type. Total CNV area measured using SS OCT and SD OCT 3 mm × 3 mm OCTA were 0.949 ± 1.168 mm(2) and 0.340 ± 0.301 mm(2), respectively (P = .001). For the 6 mm × 6 mm OCTA the total CNV area using SS OCT and SD OCT were 1.218 ± 1.284 mm(2) and 0.604 ± 0.597 mm(2), respectively (P = .0019). The field of view did not significantly affect the measured CNV area (P = .19 and P = .18 for SS OCT and SD OCT, respectively). CONCLUSION: SS OCTA yielded significantly larger CNV areas than SD OCTA. It is possible that SS OCTA is better able to demarcate the full extent of CNV vasculature.
