Wide-field angiography for diagnosis and follow-up of Eales disease: a case series / Angiografia de amplo campo para diagnóstico e monitoramento da doença de Eales: série de casos

ABSTRACT Wide-field angiography enables assessing peripheral areas with better quality and gives greater deep focus, which improves the image periphery. Some studies have proposed the usefulness of these angiographic systems in inflammatory diseases of the retina. However, few studies have evaluated this technique in Eales disease. We present a case series in which 5 eyes of 3 patients with Eales disease were evaluated by using retinal fluorescein angiography with 30º, 50º, and 150º lenses in a laser-scanning ophthalmoscope. These cases highlight the usefulness of wide-field fluorescein angiography in the diagnosis and follow-up of peripheral ischemic retinal areas in Eales disease, which enables better follow-up than possible with conventional fluorescein angiography images.

RESUMO A angiografia de campo amplo permite avaliar áreas periféricas com melhor qualidade e proporciona maior foco profundo, melhorando a imagem da periferia. Alguns estudos têm proposto a utilidade desses sistemas angiográficos nas doenças inflamatórias da retina. No entanto, poucos estudos avaliaram esta técnica na doença de Eales. Apresentamos uma série de casos em que 5 olhos de 3 pacientes com doença de Eales foram avaliados usando angiografia de fluoresceína da retina com lentes de 30º, 50º e 150º em um oftalmoscópio de varredura a laser. Esses casos destacam a utilidade da angiografia com fluoresceína de campo amplo no diagnóstico e no acompanhamento das áreas isquêmicas periféricas da retina na doença de Eales, permitindo um melhor acompanhamento do o possível com imagens por angiofluoresceinografia convencional.

Intravitreal Dexamethasone Implantation in a Behcet's Disease Patient with Macular Edema, Vasculitis after Cataract Surgery

PURPOSE: To report a case of macular edema and retinal vasculitis treated with intravitreal dexamethasone implantation in a Behcet's disease patient after cataract surgery. CASE SUMMARY: A 26-year-old male with Behcet's disease, without recurrence of uveitis for 3 months, underwent phacoemulsification and posterior chamber intraocular lens implantation for a cataract in the left eye. The preoperative best corrected visual acuity (BCVA) of the left eye was 0.15. At day 1 after surgery, his BCVA was 0.4, and slit lamp examination of his left eye revealed a mild anterior chamber reaction. At 1 week after surgery, he presented with left vision impairment, his BCVA was 0.04, and mild inflammation was observed in both the anterior chamber and the vitreous in his left eye. Unilateral macular edema was confirmed with optical coherence tomography, and fluorescein angiography revealed retinal vasculitis on the fovea and peripheral retina. Intravitreal dexamethasone implantation was performed in his left eye, 1 month after treatment, the macular edema and retinal vasculitis had improved, and the BCVA of his left eye was 0.8. CONCLUSIONS: In patients with Behcet's disease, intravitreal dexamethasone implantation can be an effective treatment option for macular edema and retinal vasculitis after cataract surgery.

Frosted Branch Angiitis Associated with Epstein-Barr Virus Infection

PURPOSE: To report a case of frosted branch angiitis (FBA) associated with Epstein-Barr virus (EBV) infection in a child. CASE SUMMARY: A 7-year-old boy presented with bilateral blurred vision. On ophthalmic examination, his best-corrected visual acuity was 20/25 in the right eye and 20/32 in the left eye. The pupils were equal, round, and reactive to light without a relative afferent pupillary defect. He had normal color vision in both eyes. Slit-lamp examination revealed no abnormalities in the anterior parts of the eyes. Fundoscopic examination revealed prominent white sheathing retinal vasculitis predominantly on the veins in all quadrants, as well as macular edema and irregular foveal reflex in both eyes. Fluorescein angiography showed normal blood flow, but late diffuse staining and leakage of the affected vessels. Spectral domain optical coherence tomography (SD-OCT) showed thickening of the vessel walls, swelling due to hyperreflective material, and hyperreflective retinal depositions. Serological tests and the serum polymerase chain reaction for EBV were positive. A diagnosis of FBA associated with EBV was made. He was treated with systemic acyclovir and steroids. The response was rapid, with improvement in visual acuity to 20/20 in both eyes by day 3. After 7 weeks, all clinical signs resolved and SD-OCT examination showed normal vessel wall thickness and the absence of hyperreflective depositions. CONCLUSIONS: EBV may present with FBA even in the absence of a systemic sign of primary EBV infection. Thus, EBV should be considered as the etiology of FBA.

Bilateral Acute Retinal Necrosis and Encephalomalacia Due to Herpes Simplex Virus Infection in a Premature Infant

Herpes simplex virus (HSV) is a common pathogen, that causes a broad spectrum of diseases, ranging from minor skin infections to severe encephalitis and widespread infections. Acute retinal necrosis (ARN), one of the most serious manifestations of HSV infection, is defined as a rapidly progressing necrotizing retinopathy that presents discrete areas of circumferential retinal necrosis, along with signs of uveitis, vitreitis, and retinal vasculitis. We encountered a case of a female infant, born at 33 weeks of gestation with a body weight at birth of 2,080 g, who had ARN and encephalomalacia due to HSV infection. ARN associated with HSV infection should be suspected when nonspecific retinal exudates are observed in neonates, especially preterm infants.

Fenómenos vasculares retinianos en esclerosis múltiple. Reporte de caso y revisión narrativa de la literatura / Retinal vascular phenomena in multiple sclerosis. Case report and narrative review of the literatura

Introducción: La esclerosis múltiple (EM) es la enfermedad inflamatoria desmielinizante del sistema nervioso central (SNC) más prevalente en el mundo. Puede presentar afectación a nivel ocular a través del compromiso inflamatorio de distinto tejidos. Objetivo: Dar a conocer la importancia del enfoque temprano de la esclerosis múltiple por parte del médico oftalmólogo. Diseño del estudio: Reporte de caso y revisión narrativa de la literatura. Resumen del caso: Se reporta el caso de una paciente joven con signos de vasculitis retiniana (VR) asociada a neuritis óptica bilateral y uveítis anterior como debut de inusual de la EM. Para la revisión narrativa se llevó a cabo la búsqueda avanzada en tres bases de datos electrónicas: PUBMED, LILACS y OVID. Por medio del gestor de referencias Zotero se realizó la eliminación de duplicados y lectura crítica de título y resumen de 162 artículos por parte de dos investigadores. Conclusión: La EM es una enfermedad crónica inflamatoria del SNC. Puede afectar las estructuras oculares de distintas maneras, una de ellas es la VR, que aunque se caracteriza por el compromiso de vasos venosos, hay que tener en cuenta presentaciones atípicas como hemorragias periarteriolares, aneurismas de grandes vasos, cierre capilar periférico, oclusión de arterial central de la retina, neovascularización del nervio óptico o aparición en etapas tempranas de la enfermedad. La fuerte asociación entre la VR y la actividad de la EM destaca la importancia del reconocimiento de patrones atípicos de una enfermedad que requiere del manejo y seguimiento oportuno por parte de neurología y oftalmología.

Background: Multiple sclerosis (MS) is the most prevalent infl ammatory demyelinating disease of the central nervous system (CNS) in the world. It may present involvement at the ocular level through the inflammatory compromise of different tissues. Objective: To provide knowledge on the importance of the early approach of multiple sclerosis by the ophthalmologist. Study design: Case report and narrative review of the literature. Case summary: We report the case of a young patient with signs of retinal vasculitis (RV) associated with bilateral optic neuritis and anterior uveitis as an unusual debut of MS. For the narrative review, the advanced search was carried out in three electronic databases: PUBMED, LILACS and OVID. Through the Zotero reference manager, the elimination of duplicates and critical reading of the title and summary of 162 articles by two researchers was carried out. Conclusion: MS is a chronic inflammatory disease of the CNS. It can affect the ocular structures in different ways, one of them is RV, which although it is characterized by the involvement of venous vessels, we must take into account atypical presentations such as periarteriolar hemorrhages, large vessel aneurysms,peripheral capillary closure, retinal artery occlusion, neovascularization of the optic nerve or appearance in the early stages of the disease. The strong association between RV and MS activity highlights the importance of recognizing atypical patterns of a disease that requires early management and follow-up by neurology and ophthalmology.

Vasculitis retinal / Retinal vasculitis

La vasculitis retinal es una enfermedad inflamatoria que amenaza la visión y afecta los vasos retinales (capilares, venas y arterias). Puede ocurrir como una condición idiopática o como complicación de enfermedades infecciosas y neoplásicas o en asociación con enfermedades sistémicas inflamatorias. Sus manifestaciones clínicas típicas incluyen revestimiento perivascular, envainamiento, filltración vascular y oclusión. Puede estar asociada con signos de isquemia retinal (puntos algodonosos y hemorragias intraretinales). Es clasificada en diferentes estadíos: inflamación, isquemia, neovascularización y complicaciones. En su diagnóstico es importante la biomicroscopia, la oftalmoscopia del segmento posterior y la prueba de angiografía fluoresceínica. Se presenta un paciente de 30 años con buena historia de salud anterior. El paciente comenzó con enrojecimiento del ojo izquierdo y la observación de flotadores en ambos ojos. Fue examinado y los signos clínicos fueron descritos en el examen oftalmológico. El examen del fondo de ojo con lente de 90 dioptrias y el oftalmoscopio binocular indirecto fue realizado para un cuidadoso examen. La retinografía del fondo y las imágenes del test de angiografía y otros estudios complementarios indicados permitieron conocer que presentaba una vasculopatía obliterativa retinal ideopática (Enfermedad de Eales), y el diagnóstico diferencial fue discutido. El tratamiento indicado fue la fotocoagulación con láser y evaluar la indicación de los estudios bioquímicos del cultivo del vítreo, por antígenos de leucocito humano, factor de crecimiento endotelial vascular e interleukinas que han sido observados en este examen(AU)

Retinal vasculitis is an inflammatory disease that threatens vision and affects retinal vessels (capillaries, veins and arteries). It may occur as an isolated idiopathic condition and as a complication of infective or neoplastic disorders, in association with systemic inflammatory diseases. Typical clinical manifestations including perivascular sheathing or cuffing, vascular leakage and occlusion. It may be associated with signs of retinal ischemia (cotton-wool spots and intra-retinal hemorrhage). It is classified into different stages: lnflamation, ischemia, neovascularization and complications. In the diagnosis, biomicroscopy and ophtalmoscopic of the posterior segment and fluorescein angiography test are important. A case report is presented of a 30-year-old male patient with a history of good health. In October 2015 the patient had started out with reddening of his left eye and the viewing of floaters with both eyes. Funduscopy was performed with a 90-dioptric lens and a binocular indirect ophthalmoscope. Fundus retinography, angiographic imaging and other complementary studies revealed an idiopathic obliterative retinal vasculopathy (Eales disease). The treatment indicated was photocoagulation, as well as a recommendation to evaluate the biochemical studies of the vitreous culture, since the test had found human leukocyte antigens, vascular endothelial growth factor and interleukins(AU)

Central serous chorioretinopathy associated with low dose systemic corticosteroid treatment of Behcet's disease / 영남의대학술지

Central serous chorioretinopathy may induce poor eyesight and serous retinal detachment. However, its exact cause has not been well established thus far. It can be associated with systemic high-dose corticosteroid treatment mainly for young and middle-aged men and may spontaneously regress or recur after withdrawal from corticosteroid. After corticosteroid administration for Behcet's disease, it is necessary to identify any ocular symptoms. Behcet's disease can lead to the development of ocular complications, such as uveitis, hypopyon, retinal vasculitis, optic neuritis, angiogenesis, secondary cataract, and glaucoma. It is possible to diagnose any of these complications via optical coherence tomography and digital indocyanine green angiography. It is easy to neglect an ocular symptom that may appear after a low-dose corticosteroid treatment as an ocular complication in patients with Behcet's disease. Thus, we report on a case concerning high-dose corticosteroid treatment with a literature review.

Vasculitis Oblioterativa Idiopática. Reporte de tres casos / Idiopathic obliterative retinal vasculitis. Three cases report

Se presentan tres casos de mujeres jóvenes que presentaron perdida de agudeza visual sin otros síntomas asociados, al examen físico se encontraron signos de vasculitis obliterativa de la retina. Se realizaron estudios complementarios tanto oftalmológicos como sistémicos, pero no se encontró ningún hallazgo sugestivo de una patología primaria como causa de la vasculitis. Se les diagnosticó entonces vasculitis obliterativa idiopática de la retina. Es escasa la información que existe en la literatura sobre esta patología, por lo cual el diagnóstico final generalmente se hace de forma tardía, retrasando también un tratamiento oportuno.

This article presents three cases of young women who presented visual acuity loss without other symptoms, the ophthalmologic exam showed evidence of obliterative vasculitis. Complementary ocular and systemic exams were made but there was no fi nding suggesting a primary pathology as the cause of the vasculitis. Thus, they were diagnosed with idiopathic obliterative retinal vasculitis. There is scarce information about this entity in the medical literature.

A Retrospective Analysis of Granulomatosis with Polyangiitis with Ocular Manifestations

PURPOSE: To analyze the treatment and prognosis of patients from our tertiary medical center with ocular and orbital involvement of granulomatosis with polyangiitis. METHODS: A retrospective analysis of the medical records of patients diagnosed with granulomatosis with polyangiitis that visited our single tertiary referral center from July 2008 to September 2014 was performed. RESULTS: A total of 51 patients diagnosed with granulomatosis with polyangiitis visited our center, and 21 of those patients had received an ophthalmologic examination. Of these, 9 patients (4 males, 5 females) had symptoms of the eye and orbit, and the clinical presentations were as follows: episcleritis, scleritis, marginal keratitis, orbital inflammation, orbital abscess, retinal vasculitis, and nasolacrimal duct obstruction. The patients each received treatments according to clinical presentation with topical, oral, or intravenous steroids or immunomodulatory agents such as cyclophosphamide. Nasolacrimal duct obstruction was treated with surgery in some cases. After an average follow-up period of 58 ± 30 months, all patients showed clinical improvement of their ocular and orbital involvement of granulomatosis with polyangiitis. CONCLUSIONS: Granulomatosis with polyangiitis is a relatively rare disease that sometimes has ocular or orbital involvement and can lead to blindness. Therefore, when ocular symptoms and signs present without a definitive cause, granulomatosis with polyangiitis must be ruled out, and appropriate treatment is needed. However, there are few published reports on the clinical presentation and prognosis of ocular and orbital involvement of granulomatosis with polyangiitis in Asians. This study showed that the incidence of ocular and orbital involvement in granulomatosis with polyangiitis was lower than previous reports.

Bilateral retinal vasculitis in a patient with lichen planus / Vasculite retiniana bilateral em um paciente com líquen plano

ABSTRACT Lichen planus (LP) is an autoimmune, inflammatory disease of unknown etiology that commonly affects the skin and mucous membranes. Retinal vasculitis is a group of vision-threatening disorders, in which autoimmunity is thought to play a role in pathogenesis. We present the case of a patient who was diagnosed with retinal vasculitis and who was followed up for mucosal LP. LP has not been reported as a cause of retinal vasculitis in the literature. We believe that the retinal vasculitis in this case was related to LP because cellular immunity plays a role in the pathogenesis of both entities.

RESUMO Líquen plano (LP) é uma doença auto-imune, inflamatória de etiologia desconhecida que normalmente afeta a pele e membranas mucosas. Vasculite retiniana engloba um grupo de doenças que ameaçam a visão em que a autoimunidade parece desempenhar um papel na sua patogênese. Apresentamos um caso que foi diagnosticado com vasculite da retina e que tinha sido acompanhado com LP de mucosa. LP não consta entre as causas de vasculite retiniana na literatura. Acreditamos que a vasculite da retina no nosso caso, foi relacionado com o LP considerando que a imunidade celular desempenha um papel na patogênese de ambas as entidades.

A Case of Aspergillus Endophthalmitis as a Preceding Symptom of Central Nervous System Lymphoma

PURPOSE: To report a rare case of Aspergillus endophthalmitis as a preceding symptom of central nervous system (CNS) lymphoma. CASE SUMMARY: A 66-year-old female was admitted to our clinic with mental change for 3 days. Seven months earlier, she had been diagnosed with retinal vasculitis in an ophthalmology clinic because of blurred vision in both eyes and was administered steroid therapy. Three months earlier, because of progressive symptoms, vitreous fluid culture had been performed and showed Aspergillus endophthalmitis. She was treated with intravitreous voriconazole injection and oral voriconazole. Initial brain magnetic resonance imaging (MRI) and cerebrospinal fluid study was normal. Two months later, a second MRI showed multiple enhancing lesions, which were aggravated on the third MRI at admission to our clinic. Although brain biopsy was not performed due to the poor condition of the patient, CNS lymphoma was suspected based on the neuroimaging. After steroid pulse therapy and whole brain radiation, follow-up neurologic examination showed improved mental state, and follow-up MRI showed remarkable shrinkage of multiple lesions. CONCLUSIONS: As Aspergillus endophthalmitis is an opportunistic infection in those with an immune-compromised state and the orbit is near the central nervous system, the clinician should be alert to concomitant disorders in CNS. For a prompt and accurate diagnosis of CNS disorder, early evaluation of neurologic symptoms beyond symptoms of endophthalmitis and neuroimaging is essential.

A Case of Repeated Dexamethasone Implantation in a Suspected Patient with IRVAN Syndrome

PURPOSE: In the present study, a case of repeated intravitreal dexamethasone implantation for a suspected idiopathic retinal vasculitis, aneurysms and neuroretinitis (IRVAN) syndrome associated with recurrent exudative retinal detachment and macular edema is reported. CASE SUMMARY: A 39-year-old female who underwent steroid pulse therapy due to Vogt-Koyanagi-Harada disease in the left eye was referred for exudative retinal detachment and macular edema. Best corrected visual acuity (BCVA) was 1.0 in the right eye and 0.5 in the left eye. Cystoid macular edema combined with serous retinal detachment was observed on spectral-domain optical coherence tomography. Fluorescein angiography revealed neovascularization and multiple macroaneurysms with fluorescein leakage in the left peripapillary area. Severe peripheral capillary non-perfusion and fluorescein leakage were also observed in both eyes. Intravitreal dexamethasone implantation was performed in the left eye and macular edema showed wax-and-wane pattern. No edema was observed after 4 additional dexamethasone implantations, however, preretinal hemorrhage occurred in the peripapillary area during treatment. Seventeen months after initiation of treatment, BCVA was 0.6 in the left eye and dry macula was maintained. CONCLUSIONS: Repeated intravitreal dexamethasone implantation was effective for recurrent macular edema in a patient suspected with IRVAN syndrome.

Inyección intravítrea de bevacizumab vs. acetato de triamcinolona en el edema macular secundario a oclusión de rama venosa retiniana / Intravitreal bevacizumab vs. triamcinolone acetonide injection to treat macular edema secondary to branch retinal vein occlusion

Objetivo: comparar los resultados del tratamiento intravítreo de bevacizumab y de acetato de triamcinolona en el edema macular secundario ante la oclusión de rama venosa retiniana. Métodos: estudio prospectivo, intervencional, aleatorio y comparativo realizado en 34 pacientes. El grupo 1 (16 pacientes) con inyección intravítrea de acetato de triamcinolona y el grupo 2 (18 pacientes) con inyección de bevacizumab hasta completar 3 dosis en cada grupo, seguida la tercera dosis de grid macular. La dosis inicial fue a los 3 meses de la afección, y la evaluación final a los 12 meses. Se evaluó la agudeza visual mejor corregida (Snellen), grosor macular y complicaciones. Resultados: en el grupo 1 la mejor agudeza visual con corrección evolucionó de 0,29 (0,05-0,5) a 0,64 (0,05-1,0); en el grupo 2 de 0,24 (0,05-0,5) a 0,66 (0,11,0). El grosor macular en el grupo 1, de 551,3 (346-967) micras, mejoró a 204,06 (112-449) micras; en el grupo 2, de 546,2 (283-1020) micras, hasta un grosor retinal foveal de 181,05 (112-312) micras. Como complicaciones, en el grupo 1 hubo un incremento de la tensión ocular en el 25,0 por ciento de los pacientes y una progresión de catarata en el 12,5 por ciento. Conclusiones: el tratamiento de inyección intravítrea de bevacizumab en el edema macular secundario a oclusiones venosas de rama retiniana muestra mejor resultado que el de acetato de triamcinolona. También son menores las complicaciones asociadas al bevacizumab(AU)

Objective: to compare the results of the intravitreal treatment with bevacizumab and with triamcinolone acetonide in the macular edema secondary to branch retinal vein occlusion. Methods: a prospective, interventional, random and comparative study was carried out in 34 patients. The first group (16 patients) received intravitreal triamcinolone acetonide injection whereas the second group (18 patients) had bevacizumab injection up to completing three doses in each group, followed by a third dose of macular grid. The initial dose was applied three months after the occurrence of edema and the final evaluation was made 12 months afterwards. Best corrected visual acuity (Snellen's chart), the macular thickness and complications were assessed. Results: in the first group, the best corrected visual acuity increased from 0,29 (0,05-05) to 0,64 (0,05-1,0) whereas in the second group it went from 0,24 (0,05-05) to 0,66 (0,1-1,0).The macular thickness of 551,3 (346-967) microns of the first group improved when reaching 204,06 (112-449) microns and that of the second group went from 546,2 (283-1020) microns to 181,05 (112-312) microns. As to the complications, 25 percent of patients of the first group experienced eye hypertension, and 12,5 percent of patients in the same group had cataract progression. Conclusions: intravitreal bevacizumab injection treatment of the macular edema secondary to branch retinal vein occlusion was better than that based on triamcinolone acetonide injection. The complications associated to bevacizumab treatment were fewer(AU)

Red eyes in the necropsy floor: twenty cases of hyphema in dogs and cats / Olhos vermelhos na sala de necropsia: vinte casos de hifema em cães e gatos

Hyphema (hemorrhage within the anterior chamber of the eye) can be caused by several mechanisms and can easily be detected in routine ophthalmic or necroscopic examination as discolored red eye(s). The purpose of this study is to report the cause of hyphema diagnosed as a postmortem finding in dogs and cats. Twenty cases, 14 dogs and six cats of several ages and breeds and of both sexes were included in the study. Hyphema presented as a unilateral (14 cases out of 20) or bilateral (6/20) disorder in dogs and cats and extension of hemorrhage varied from minimal to diffuse. Hyphema was secondary to systemic disease (15/20) or occurred as a primary ocular lesion (5/20) in four dogs and one cat. Primary hyphema was always unilateral. In four of these cases, the cause of hyphema was trauma and remaining case was caused by phacoclastic uveitis in a dog with bilateral hypermature cataract. Various causes of bleeding disorders were found related to secondary hyphema: in decreasing order of frequency, they included vasculitis (8/15), systemic hypertension (5/15), and acquired coagulopathies (2/15). Vasculitis due to feline infectious peritonitis accounted for half of the cases (n=3) of systemic hyphema in cats. The various pathological aspects and pathogenesis of hyphema in dogs and cats are described and discussed...

Hifema, hemorragia na câmara anterior do olho, pode ser causada por vários mecanismos e pode facilmente ser detectada no exame oftálmico de rotina ou na necropsia como olho(s) vermelhos(s). O objetivo deste trabalho é relatar as causas de hifema diagnosticado como um achado postmortem em cães e gatos. Vinte casos, 14 cães e seis gatos de várias idades e raças, e de ambos os sexos foram incluídos no estudo. O hifema em cães e gatos teve uma apresentação unilateral (14 casos dos 20) ou bilateral (6/20), e a extensão da hemorragia variou de mínima a difusa. O hifema era secundário à doença sistêmica (15/20) ou ocorreu como lesão ocular primária em cinco dos 20 casos (quatro cães e um gato). O hifema primário foi sempre unilateral; em quatro desses casos, a causa foi traumatismo e o caso restante foi causado por uveíte facoclástica em um cão com catarata hipermadura bilateral. Várias causas de distúrbios hemorrágicos foram encontradas em relação ao hifema secundário: em ordem decrescente de frequência foram: vasculite (8/15), hipertensão sistêmica (5/15) e coagulopatias adquiridas (2/15). Os vários aspectos patológicos e a patogênese do hifema são descritos e discutidos...

Unusual presentation of a multiple sclerosis case involving central retinal artery occlusion

The term intermediate uveitis [IU] refers to a subgroup of uveitis in which the vitreous is the site of greatest inflammation. Patients with multiple sclerosis [MS] have a greater frequency of IU compared with the general population. The IU associated with MS is characterized by the presence of pars planitis [occasionally accompanied by anterior uveitis] and the presence of peripheral retinal vasculitis in the form of periphlebitis [venous sheathing] in 6-26% of patients. We present a patient with an unusual initial presentation of MS involving central retinal artery occlusion [CRAO] in the right eye [RE]. Although retinal vascular changes are asymptomatic in the majority of MS patients, the spectrum of impairment ranges from simple peripheral retina periphlebitis to the presence of peripheral occlusive retinal vasculitis in 6.5% of patients. This atypical case may represent an extreme of the spectrum of retinal vasculitis associated with demyelinating disease

Correlation between Fluorescein Angiographic Findings and Visual Acuity in Behcet Retinal Vasculitis

PURPOSE: To identify significant fluorescein angiographic (FA) characteristics associated with visual acuity (VA) in Behcet retinal vasculitis. MATERIALS AND METHODS: Retrospective review of 86 eyes of 48 patients (age: 35.6+/-10.2 years) with Behcet retinal vasculitis were performed. VA and FA findings as well as correlation between them were assessed. RESULTS: The mean initial VA of eyes with posterior pole-involved vasculitis (63 eyes; 73.3%) was significantly worse than that of those with peripheral vasculitis (23 eye; 26.7%) (logarithm of the minimum angle of resolution VA: 0.554+/-0.572 vs. 0.078+/-0.148; p<0.0001). Subgroup analysis revealed a more severe and diffuse pattern of vascular leakage in posterior pole-involved vasculitis compared to peripheral vasculitis (p<0.0001). Retinal vascular leakage (beta=0.345; p<0.0001), optic disc hyperfluorescence (beta=0.147; p=0.032), and macular leakage (beta=0.107; p=0.047) were significantly associated with worse initial VA. During the follow up (mean: 33.3+/-17.9 months), the change of leakage showed no significant correlation with change of VA in posterior pole-involved vasculitis (tau=0.199, p=0.092). CONCLUSION: Posterior pole involvement, the degree of retinal vascular leakage, optic disc hyperfluorescence, and macular leakage are significantly associated with VA in Behcet retinal vasculitis.
