Silent polypoidal choroidal vasculopathy in a patient with angioid streaks / Vasculopatia polipoidal de coróide quiescente em um paciente com estrias angióides

ABSTRACT We present a case of silent polypoidal choroidal vasculopathy (PCV) in a patient with angioid streaks. PCV was detected during a routine ophthalmic examination and confirmed by fluorescein angiography, indocyanine green angiography, and optical coherence tomography. After 2 years of follow-up, the PCV remained silent without any complications. We report this rare coexistence and review literature on this topic.

Após 2 anos de seguimento a vasculopatia polipoidal de coroide permaneceu quiescente, sem qualquer complicação. Nós relatamos esta coexistência rara e apresentamos revisão da literatura.

Drastic effect of ranibizumab on choroidal neovascularization in idiopathic angioid streaks / Efeito dramático do ranibizumabe na neovascularização de coroide em estrias angióides idiopáticas

ABSTRACTA 28-year-old man presented with bilateral vision loss. His best-corrected visual acuity (BCVA) was 0.3 in the right eye (OD) and 0.6 in the left eye (OS). Fundoscopy and fluorescein angiography showed angioid streaks encircling the optic discs of both eyes (OU). Spectral Domain Optical Coherence Tomography (SD-OCT) showed bilateral macular serous detachment. Systemic and ocular screening tests showed no specific cause for the angioid streaks. The patient had previously received pegaptanib sodium injection on three occasions, photodynamic therapy in OS, and no treatment in OD. Upon intravitreal injection of ranibizumab (twice in OU), subretinal fluid was nearly eliminated in OU. BCVA increased to 0.6 in OD and 0.9 in OS, and remained improved until 6 months after treatment.

RESUMOUm homem de 28 anos apresentou-se com perda de visão bilateral. A melhor acuidade visual corrigida (BCVA) era 0,3 no olho direito (OD) e 0,6 no olho esquerdo (OS). A fundoscopia e a angiofluoresceinografia demonstraram estrias angióides ao redor dos discos ópticos em ambos os olhos (OU). A tomografia de coerência óptica de domínio espectral (SD-OCT) demonstrou descolamento seroso macular bilateral. Testes de triagem sistêmicas e oculares não mostraram causa específica para estrias angióides. O paciente tinha um historia de três tratamentos com injeção de pegaptanibe sódico e terapia fotodinâmica em OS e nenhum tratamento em OD. Após a injeção intravítrea de ranibizumabe (duas vezes em OU), fluido sub-retiniano quase desapareceu em OU. BCVA melhorou para 0,6 em OD e 0,9 em OS e não se alterou até o sexto mês de tratamento.

Estrías angioides y tumor hipofisario: ¿asociación o hallazgo incidental? / Angioid streaks and pituitary tumor: ¿association or incidental finding?

Las estrias angioides de la retina se aprecian como líneas dentelladas rosadas u oscuras radiando irregularmente en todas direcciones desde el área peripapilar hacia la periferia de la retina. Corresponden a roturas del componente elástico de la membrana de Bruch. Su presencia indica una enfermedad sistémica siendo las más importantes el pseudoxantoma elástico, la enfermedad de Paget ósea y la drepanocitosis, Los tumores hipofisiarios raramente se han asociado a está condición existiendo apenas tres descriptores en la literatura. A estas adicionamos tres pacientes más, no obstante, aun no puede asegurarse si se trata de una asociación o de un simple hallazgo incidental.

Retinal angioid streaks can be seen as rough lines pink or dark, irregularly radiating in all directions from the peripapilar area to the periphery of the retina. They correspond of breaks in the elastic component of the Bruch membrane. Its presence indicates a systemic disease being the most important pseudoxanthoma elasticum, bone Paget's disease and sickle cell disease. Pituitary tumors have rarely been associated with this condition and exist just three descriptions in the literature. To these we add three more patients, however, still not be tightened if it's an association or a simple incidental finding.

Combination treatment of low fluence photodynamic therapy and intravitreal ranibizumab for choroidal neovascular membrane secondary to angioid streaks in Paget's disease – 12 month results.

Angioid streaks also called Knapp striae are small breaks in the Bruch's membrane and have been reported with a host of systemic diseases. Rupture of streaks or development of secondary choroidal neovascular membrane (CNVM) carries a dismal visual prognosis. We report the successful treatment of CNVM secondary to Paget's disease using low fluence photodynamic therapy (PDT) and intravitreal ranibizumab.

A Case of Intravitreal Bevacizumab Injection for the Treatment of Choroidal Neovascularization in Angioid Streaks

A 56-year-old Korean woman presented with decreased visual acuity of the right eye. She had a history of two photodynamic therapy treatments for choroidal neovascularization (CNV) due to angioid streaks in her left eye with central scarring and low visual acuity. She was diagnosed with subfoveal CNV due to angioid streaks in her right eye and treated with six intravitreal bevacizumab (1.25 mg / 0.05 mL) injections over one year. Best corrected visual acuity improved from 20 / 125 at baseline to 20 / 50 at the final visit. The area of CNV had changed into a fibrotic scar by the final visit, and fluorescein angiography and indocyanine green angiography revealed no evidence of leakage. Optical coherence tomography showed that central macular thickness decreased from 311 microm at baseline to 203 microm with complete resolution of subretinal and intraretinal fluid at the final visit. Intravitreal bevacizumab for CNV associated with angioid streaks prevented the progression of disease and resulted in the improvement of visual acuity after one year of follow-up in our patient.

Estrias angióides: análise fundoscópica de 317 casos / Angioid streaks: fundoscopic analysis of 317 cases

OBJETIVO: Avaliar a presença de neovascularização de coróide (NVC) e suas seqüelas em pacientes portadores de estrias angióides (EA). MÉTODOS: Foram analisados retrospectivamente os prontuários de pacientes atendidos no Instituto Suel Abujamra, São Paulo (SP), Brasil, de 1976 a 2006. Considerou-se a idade, cor da pele, queixas na primeira consulta, acuidade visual e aspecto fundoscópico com especial atenção a lesões disciformes por NVC sub-retinianas ativas ou cicatrizadas. RESULTADOS: Dos 317 pacientes estudados, 163 (51,5 por cento) eram homens. A média de idade era de 57 anos com desvio-padrão de 12,4 anos, mínimo de 11 e máximo de 91 anos. Quanto a cor da pele, 209 (66,2 por cento) eram brancos, 91 (29,0 por cento) amarelos,11 (3,7 por cento) negros, e 3 (1,1 por cento) pardos. As EA eram bilaterais em todos os pacientes, e de 631 olhos pesquisados, 348 (55,1 por cento) tinham EA de coloração marrom, 153 (24,2 por cento) cinza e 124 (19,6 por cento) marrom-avermelhada. No momento do diagnóstico, as acuidades visuais medidas na tabela de Snellen foram piores que 20/200 em 40,4 por cento dos olhos. Comprovou-se a ausência de NVC em 103 (32,5 por cento) pacientes. As lesões NVC unilaterais estavam presentes em 112 (35,3 por cento) e bilaterais em 99 (31,2 por cento). Quanto à localização, 242 (74,3 por cento) eram maculares, 45 (13,8 por cento) extra-maculares e 38 (11,7 por cento) mistas. CONCLUSÃO: As EA são importante causa de cegueira legal e podem passar despercebidas no exame oftalmológico de rotina quando não apresentam lesões maculares disciformes ativas ou cicatrizadas. A importância deste estudo é o expressivo número de casos e alertar os oftalmologistas quanto à necessidade de um exame fundoscópico minucioso, a fim de monitorá-las, diagnosticar e tratar precocemente a NVC.

PURPOSE: To evaluate the presence of choroidal neovascularization (CN) and their sequels in patient bearing angioid streaks (AE). METHODS: Case records of patients assisted from 1976 to 2006 at the Instituto Suel Abujamra located in the city of São Paulo, Brazil, were analyzed retrospectively. Age, skin color; patient complaints at the first evaluation, visual acuity, fundoscopic aspects with special attention to disciform lesions to active or scarred subretinal CN were considered. RESULTS: Among the 317 studied patients, 163 (51.5 percent) were men. The average age was 57, with standard deviation of 12.4 years, minimum 11 and maximum 91 years. Regarding skin color, 209 (66.2 percent) were white, 91 (29.0 percent) were yellow, 11 (3.7 percent) were black, and 3 (1.1 percent) were mulatto. AE were bilateral in all patients; of 631 researched eyes, 348 (55.1 percent) had brown color AE, in 153 (24.2 percent) they were gray and in 124 (19.6 percent) reddish brown. Upon diagnosis, visual acuities measured with the Snellen chart were worse than 20/200 in 40.4 percent of the eyes. CN absence was proven in 103 (32.5 percent) patients. The unilateral lesions were present in 112 (35.3 percent) and bilateral lesions were present in 99 (31.2 percent). Regarding location, 242 (74.3 percent) were macular, 45 (13.8 percent) were extramacular and 38 (11.7 percent) were both macular and extramacular. CONCLUSION: AE are an important cause of legal blindness and can be easily bypassed in an ophthalmic routine examination in the absence of active or disciform neovascular lesions. The expressive number of these cases brings us to the importance of this study. It highlights the need for a meticulous fundoscopic examination in order to improve diagnoses of the disease and early treatment of CN.

Indocyanine green-mediated photothrombosis for choroidal neovascularization in angioid streaks / Fototrombose mediada por indocianina verde para o tratamento de neovascularização de coróide em estrias angióides

PURPOSE: To investigate the effect of indocyanine green-mediated photothrombosis on choroidal neovascularization secondary to angioid streaks. METHODS: Six eyes of 5 patients with an average age of 70 years were diagnosed to have subfoveal choroidal neovascularization secondary to angioid streaks. Therapy was indicated if choroidal neovascularization was considered to be active, according to evidence of fluorescein leakage on angiograms, as well as presence of intra- or subretinal fluid on optical coherence tomography. Patients received photothrombosis at baseline with retreatment as necessary at 3, 6 and 9 months follow-up. Fluorescein leakage was assessed at 3, 6 and 9 months, along with foveal thickness measured by optical coherence tomography. Indocyanine green angiography was performed initially and whenever retreatment was considered. Retreatment was performed whenever there was evidence of increased leakage on fluorescein angiograms at follow-up visits. RESULTS: The mean follow-up was 13.3 months. All eyes had at least 12 months follow-up. Two eyes underwent retreatment. Three eyes had visual acuity improvement and three eyes had stabilization. All patients showed less fluorescein leakage on final angiograms and reduced foveal thickness upon optical coherence tomography measurement. CONCLUSION: Photothrombosis is a feasible procedure for choroidal neovascularization secondary to angioid streaks. Lesion analysis showed anatomical improvement in most cases in this series. Further studies are warranted to evaluate long-term results of this treatment.

OBJETIVO: Investigar os efeitos da fototrombose mediada por indocianina verde sobre a neovascularização de coróide secundária a estrias angióides. MÉTODOS: Seis olhos de 5 pacientes com média de 70 anos de idade tinham o diagnóstico de neovascularização de coróide secundária a estrias angióides. O tratamento foi indicado para neovascularização de coróide ativa, avaliada pelo vazamento na angiofluoresceinografia e pela presença de fluido intra ou sub-retiniano pela tomografia de coerência óptica. Os pacientes receberam tratamento inicial com indocianina verde, e a seguir foram re-tratados conforme necessário com 3, 6 e 9 meses. Nessas ocasiões avaliava-se o vazamento e a espessura foveal. A angiografia com indocianina verde foi realizada inicialmente e sempre que o re-tratamento era considerado, nos casos em que havia aumento de vazamento pela angiofluoresceinografia nas visitas de seguimento. RESULTADOS: O tempo médio de seguimento foi de 13,3 meses. Todos os olhos atingiram um seguimento de pelo menos 12 meses. Dois olhos foram submetidos a re-tratamento. Três olhos apresentaram melhora e três olhos apresentaram estabilização da acuidade visual. Todos os pacientes apresentaram diminuição final do vazamento e da espessura foveal. CONCLUSÃO: Indocianina verde é procedimento factível para o tratamento de neovascularização de coróide secundária a estrias angióides. A análise das lesões mostrou melhora anatômica na maioria dos casos desta série. Mais estudos são necessários para avaliar os resultados a longo prazo deste tratamento.

Intravitreal bevacizumab (Avastin) in choroidal neovascular membrane in angioid streaks.

Angioid streaks are crack-like dehiscences in the Bruch's membrane, which predispose to the development of a choroidal neovascular membrane (CNVM) that carries a poor visual outcome. We report successful treatment in a 25-year-old woman with bilateral angioid streaks and subfoveal CNVM in the left eye who received two doses of intravitreal bevacizumab (1.25 mg) injections six weeks apart, resulting in rapid regression of the CNVM.

Photodynamic Therapy With Verteporfin for Choroidal Neovascularization in Patients with Angioid Streaks

PURPOSE: To evaluate the functional and anatomic outcomes of photodynamic therapy (PDT) for choroidal neovascularization (CNV) in patients with angioid streaks. METHODS: The authors retrospectively evaluated 6 consecutive patients (6 eyes) with CNV secondary to angioid streaks. All patients were treated with standard PDT with verteporfin protocol. Standardized protocol refraction, visual acuity testing, ophthalmologic examination, color photographs, fluorescein angiograms and indocyanin angiograms were used to evaluate the results of PDT with verteporfin. Main outcome measures were visual acuity and CNV size. RESULTS: Their mean age was 61.3+/-5.50 years (range, 53-68 years). Follow-up time ranged from 12 to 38 months with mean of 20.5+/-10.91 months. The mean visual acuity at baseline was 20/100 (range 20/25-20/500), and the mean visual acuity at the last examination was 20/320(range 20/125-counting finger). The mean greatest linear dimension (GLD) at baseline was 2400+/-766.81 micrometer, and the mean GLD at the last examination was 3483+/-444.59 micrometer. CONCLUSIONS: PDT for CNV associated with angioid streaks seemed to slow down but not prevent the progression of the disease and associated visual loss.
