PURPOSE: To report a 16-year long-term follow-up of a patient with acute multifocal hemorrhagic retinal vasculitis (Blumenkranz syndrome). A 21-year old male was seen in 1994 with acute multifocal hemorrhagic retinal vasculitis (Blumenkranz syndrome), first in the left eye, and later in the right eye. He was treated with retinal photocoagulation in areas of retinal ischemia and oral steroids, followed by sequential annual fundus examination and photography for 16 years. Vision improved to 20/25 in both eyes after retinal ischemic areas photocoagulation and oral steroids, and his vision has been maintained for 16 years. Photocoagulation of retinal ischemia and oral steroids are effective for the treatment of acute multifocal hemorrhagic retinal vasculitis (Blumenkranz syndrome).

Relato de caso com acompanhamento por 16 anos de um paciente com a vasculite hemorrágica multifocal aguda (síndrome de Blumenkranz). Um paciente de 21 anos de idade foi diagnosticado em 1994 com a vasculite hemorrágica multifocal aguda (síndrome de Blumenkranz), primeiro no olho esquerdo e depois no olho direito. Foi tratado com fotocoagulação retiniana nas áreas retinianas isquêmicas e corticosteroide oral e seguido por exames complementares da retina por 16 anos. A visão melhorou para 20/25 em ambos os olhos após a fotocoagulação retiniana nas áreas isquêmicas da retina e corticosteroide oral permanecendo assim até o momento por 16 anos. A fotocoagulação retiniana nas áreas isquêmicas e o uso de corticosteróide oral são tratamentos efetivos para a vasculite hemorrágica multifocal aguda (síndrome de Blumenkranz).

Acute multifocal hemorrhagic retinal vasculitis (Blumenkranz syndrome) is an uncommon disease that was first described in seven patients over a 5-year period to 1988(1).
These patients have features including subtle hemorrhagic multifocal retinal vasculitis, frequently in the posterior segment and predominantly in men. The syndrome is bilateral, but with a degree of asymmetric involvement that causes abrupt visual loss in the affected eye without systemic symptoms or a proven systemic etiology. Other signs of this disease are retinal hemorrhage that appears to result from vasculitic occlusion of the retinal veins, papillitis, non-confluent posterior retinal infiltrates, vitreous cellular inflammation and late complications such as secondary vitreous hemorrhage, neovascularization, epiretinal membrane, rubeosis iridis, and neovascular glaucoma.
These symptoms are similar to those in a variety of other disorders such as Behçet's disease(2,3), ocular syphilis(4), ocular toxoplasmosis(5), Eales' disease(6), sarcoidosis(7,8) and viral diseases(9-12), but Blumenkranz syndrome occurs in otherwise healthy patients.
Final visual acuity in patients with Blumenkranz syndrome ranges from 20/20 to light perception. Seven of 14 eyes in the first description of the disease had visual acuity of 20/40 or better.
The aim of this case report is to show the most long-term follow-up of a patient with Blumenkranz syndrome, who was initially reported in 1994(13).
A 21-year-old man was seen in 1994 and referred for further evaluation after abrupt visual loss in the left eye. Examination at that time demonstrated visual acuity of 20/400 in the left eye and 20/20 in the right. Slit-lamp examination demonstrated clear cornea with 1+ cell and flare in the anterior chamber of the right eye. No keratic precipitates were seen, and intraocular pressure was 16 mmHg in the left eye and 14 mmHg in the right. The left eye showed intraretinal hemorrhages in the posterior pole. Fluorescein angiography demonstrated a combination of blocked fluorescence and retinal capillary non-perfusion in areas of hemorrhage (Figure 1). Fluorescein angiography of the right eye was normal (Figure 2).
Laboratory evaluation included a normal leukocyte count and hematocrit, Wintrobe's sedimentation rate of 41, a non-reactive rapid plasma reagin test and fluorescent antibody titer, and normal SMA 6, chest X-ray, liver function tests, lumbar puncture, and electrocardiography. The patient had negative IgG and IgM titers for toxoplasmosis. Fluorescent antinuclear antibody and VDRL test were negative for syphilis. Total T and B cell counts and helper/suppressor cell ratio were within normal limits. Serum antibodies to herpes simplex virus, cytomegalovirus and Epstein-Barr virus were not found. Results of serum immunoelectrophoresis were normal, and skin biopsy after histamine administration was negative.
The patient was treated with oral prednisone (40 mg/day) and acyclovir (400 mg every 8 h), but no visual improvement occurred.
We decided to treat areas of retinal ischemia with photocoagulation and to maintain therapy with oral steroids. After 1 month, the final visual acuity in the left eye was 20/25. After 1 month of treatment, a new subtle visual loss occurred in the right eye and visual acuity was 20/400. Slit-lamp examination revealed the same clinical findings as in the right eye: clear cornea, 1+ cell and flare in the anterior chamber, no keratic precipitates, and intraocular pressure of 15 mmHg in the right eye and 15 mmHg in the left. Intraretinal hemorrhages were seen in the posterior pole. Fluorescein angiography demonstrated a combination of blocked fluorescence and retinal capillary non-perfusion in areas of hemorrhages (Figure 3).
We decide to treat the patient with oral prednisone (40 mg/day) and areas of retinal ischemia with photocoagulation, resulting in final visual acuity of 20/25 after 1 month. Figures 4, 5 and 6 show the scars of retinal photocoagulation.
We present an unusual case of the most long-term follow-up of 16 years of a 21-year-old man with acute multifocal hemorrhagic retinal vasculitis, after treatment with photocoagulation of retinal ischemia and oral steroids.
In our patient, oral prednisone and retinal photocoagulation were effective, but acyclovir was ineffective. This represents the best model to treat the initial form of this disease. Final visual acuity improved in both eyes to 20/25, and our results agree with those obtained in 50% of the cases in the first description of this disease(1).
The clinical features of this disease resemble the ocular findings of several other diseases, including Behcet's disease, Eales' disease, sarcoidosis, syphilis, toxoplasmosis, and herpes simplex and other viral diseases. However, laboratory results for this patient were negative at initial presentation and remained so at follow-up, indicating that he was otherwise healthy and had no other ocular or systemic involvement.
If our patient had Behçet's disease, his clinical and systemic findings failed to satisfy the diagnostic criteria. The cause of Behçet's disease is unknown. Numerous causes have been proposed, including infection, toxins, and genetic factors. No virus has been isolated to date. An autoimmune and genetic cause has gained acceptance.
There is no specific diagnostic test for Behçet's disease, and its diagnosis is based on features that are present during history taking and examination. Five different sets of criteria for the diagnosis of Behçet's disease have been used, and this lack of agreement has hindered the interpretation of different studies. A new international study group(14) has agreed upon diagnostic criteria for Behçet's disease. These criteria require the presence of oral ulceration plus any two of the following: genital ulceration, typical eye and skin lesions, a positive skin test for pathergy. None of these was present in our patient. Moreover, if this was a viral disease, the failure of acyclovir was contradictory.
Blumenkranz syndrome appears to be a specific disease with unknown etiology that responds well to photocoagulation of retinal ischemia and oral steroids.
The present case with long-term follow-up of Blumenkranz syndrome has helped us to establish until now the best model for initial treatment and supports the conclusions of those who first described this illness.
