ABSTRACT
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.

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.

Eales disease is an obliterative vasculopathy that usually involve peripheral retina of young adults. It is thought to be a nonspecific tissue response to a number of agents and exact etiology remains unknown. Many diseases reflect some alterations in electrophoretic pattern of serum proteins. This study was carried out to investigate electrophoretic pattern of serum proteins in Eales disease so as to throw some light on possible etiological factors in these patients. Thirty-two patients of Eales disease constituted the subject material for this study. Paper electrophoresis of the sera was performed by cellulose acetate method on Whatman filter paper No.10 using barbitone buffer of pH 8.6. Both patients and controls underwent complete ocular and clinical examination and followed up for one year. This was a descriptive study. Ten patients [30%] had raised total serum proteins out of 32 patients and ten patients [30%] had raised gamma globulin. Serum albumin was decreased in seven patients [20%] out of thirty-two patients of Eales disease. In our study 30% increase in total serum proteins and gamma globulins in Eales disease patients points to a possible role of some immunological process which manifests as retinal perivasculitis in eyes. An increase in erythrocyte sedimentation rate in >85% of cases is consistent with this suggestion
