ABSTRACT
ABSTRACT Visceral Leishmaniasis, also know as Kala-azar, is a parasitic tropical disease caused by protozoa of the genus Leishmania donovani. It is an endemic disease in many countries. It affects approximately 1,5 million people every year, and when associated with mal-nutrition and co-infection it may be fatal. Fever, hepatosplenomegaly, and pancytopenia is its typical clinical picture. Ocular manifestations of Kalaazar are relatively rare and can affect either anterior or posterior segment of the eye. We report a patient with kala-azar presenting intraretinal hemorrhages that regress completely after the successful treatment for visceral leishmaniasis.
RESUMO Leishmaniose visceral, também conhecida como calazar é uma doença tropical parasitária, causada pelo protozoário do gênero Leishmania donovan uma doença endêmica em muitos países. Afeta aproximadamente 1,5 milhões de pessoas durante todo ano e quando associada à desnutrição e coinfecção pode ser fatal. Febre, hepatoesplenomegalia e pancitopenia e o quadro típico. Manifestações oculares são raras e podem afetar tanto o segmento anterior como o posterior do olho. Relatamos o caso de um paciente com calazar e hemorragia intrarretiniana que regrediu após tratamento para leishmaniose visceral.

We report the case of a patient with congenital toxoplasmosis and submacular hemorrhage caused by a neovascular membrane who underwent an intravitreal injection of C3F8 and bevacizumab, and had a good visual recovery.
Relatamos o caso de uma paciente com toxoplasmose congênita e hemorragia submacular por uma membrana neovascular submetida à injeção intravítrea de C3F8 e bevacizumabe, com boa recuperação visual.

O objetivo desta série de casos foi demonstrar se a aplicação de bevacizumab e gás perfluoropropano (C3F8) intravítreos beneficiariam o deslocamento da hemorragia sub-retiniana dos pacientes com degeneração macular relacionada à idade. Foi realizada uma série retrospectiva de 5 olhos que tinham recebido injeção intravítrea simultânea de bevacizumab e C3F8. Os resultados foram medidos pelo grau de deslocamento de sangue sob a fóvea, pela acuidade visual final e pelas complicações intraoperatórias. Na apresentação inicial, a idade média dos pacientes foi de 72,6 ± 8,9 anos e a duração média dos sintomas foi de 13 ± 9,7 dias. Dos 5 pacientes do estudo, 3 (60 por cento) eram homens e 2 (40 por cento) mulheres. O sucesso do deslocamento da hemorragia submacular foi alcançado em 4 pacientes. A média de acuidade visual pré-operatória foi de 1,12 ± 0,34 logMAR e pós-operatório foi de 0,92 ± 0,4 logMAR. Não foram observados nenhum caso de descolamento da retina, endoftalmite, hemorragia vítrea, uveíte, catarata e hipertensão ocular. A injeção intravítrea bevacizumab e C3F8, juntamente com a posição pronada pode ser uma valiosa opção terapêutica nos olhos com degeneração macular relacionada à idade neovascular e hemorragia sub-retiniana a fim de deslocar o sangue para fora da área foveal.
The purpose of this case series is to describe if the intravitreal use of bevacizumab and perfluoropropane gas (C3F8) would be beneficial to the displacement of subretinal hemorrhage in patients with age-related macular degeneration (AMD). A retrospective study of 5 eyes that received concurrent intravitreal injection of bevacizumab and C3F8 was performed. The results were graded according to blood displacement under the fovea, best final visual acuity and intraoperative complications. At the initial presentation, mean age of patients was 72.6 ± 8.9 years-old and duration of symptoms was 13 ± 9.7 days. From the 5 patients, 3 (60 percent) were male and 2 (40 percent) female. The success of submacular hemorrhage full displacement was achieved in 4 patients. The mean preoperative visual acuity (VA) was 1.12 ± 0.34 logMAR and the mean postoperative VA was 0.92 ± 0.4 logMAR. No cases of retinal detachment, endophthalmitis, vitreous hemorrhage, uveitis, cataracts and increased intraocular pressure were noted during the follow-up period. Intravitreal bevacizumab and C3F8 injection, associated to prone position can be a valuable therapeutic option for eyes with neovascular age-related macular degeneration and subretinal hemorrhage to the blood displacement out of the foveal area.

Relata-se o caso de um paciente de 35 anos de idade, sexo masculino, com história de trauma cranioencefálico, que evoluiu com hemorragia pré-macular da síndrome de Terson no olho esquerdo. Após 45 dias de conduta expectante, sem resolução da hemorragia, foi realizada injeção intravítrea de gás hexafluoreto de enxofre e tPA, evoluindo com absorção quase completa da hemorragia após uma semana e considerável melhora da acuidade visual. Descreve-se também aspectos importantes da síndrome de Terson e da injeção intravítrea de gás e tPA por meio de revisão da literatura.
The case of a 35 year-old male patient is reported. The patient had a clinical history of craniocerebral trauma and premacular hemorrhage of Terson syndrome in the left eye. After waiting for 45 days, without hemorrhage resolution, the patient received an intravitreal injection of sulfur hexafluoride gas and tPA; an almost complete hemorrhage absorption occurred after a week as well as a considerable improvement of visual acuity. In the report, relevant aspects of Terson syndrome and of intravitreal injection of gas and tPA are also described through a literature review.

PURPOSE: To determine and compare the clinical characteristics, visual prognosis and treatment of hemorrhagic polypoidal choroidal vasculopathy (HPCV) with those of hemorrhagic choroidal neovascularization (HCNV) due to age-related macular degeneration (ARMD). MATERIALS AND METHODS: Retrospective analysis of 44 consecutive eyes with a submacular hemorrhage comprising more than 50% of the neovascular lesion. Patients were diagnosed as having HPCV or HCNV on the basis of indocyanine green angiography. RESUTLS: Of the 44 eyes with submacular hemorrhage, 26 were classified as HPCV and 18 as HCNV. The baseline patient characteristics were similar for both groups. At the final follow-up the HPCV group had 17 eyes showing visual improvement, four showing maintained vision, and five showing visual deterioration. In contrast, the HCNV group had four eyes showing visual improvement, one showing maintained vision, and 13 showing visual deterioration. Visual acuity of 0.05). CONCLUSION: PCV accounts for the largest proportion of submacular hemorrhage in Koreans. PCV showed a better visual prognosis than CNV.
