Chikungunya virus iridocyclitis in Fuchs’ heterochromic iridocyclitis.

We are reporting a case of bilateral Fuchs’ heterochromic iridocyclitis with chikungunya virus infection in the left eye. A 20-year-old female was presented with a past history of fever suggestive of chikungunya with bilateral Fuchs’ heterochromic iridocyclitis and complicated cataract. She had a tripod dendritic pattern of keratic precipitates by confocal microscopy in the left eye with a stippled pattern of keratic precipitates in both eyes. The real-time polymerase chain reaction (RT-PCR) assay in the aqueous humor detected 98 copies/ml of chikungunya virus RNA. The patient underwent clear corneal phacoemulsification with in-the-bag intraocular lens implantation in the left eye with a good visual outcome. This is the first report where the presence of chikungunya virus RNA has been associated with a case of bilateral Fuchs’ heterochromic iridocyclitis.

Hanseníase ocular: uma abordagem histórica / Ocular leprosy: a historical approach

Houve uma acentuada queda na prevalência da hanseníase nas últimas três décadas. Contudo, a incidência não diminuiu na mesma proporção. Hoje, três anos após a última data estipulada pela Organização Mundial da Saúde para o controle da hanseníase, pacientes considerados curados ainda necessitam de cuidados especiais por causa de suas incapacidades e reações imunológicas. A literatura médica refere cegueira em 4 por cento a 11 por cento dos pacientes estudados e, mais de 20 por cento com graves problemas visuais devido a exposição da córnea, invasão bacilar e hipersensibilidade; estes mecanismos resultam em uma população de aproximadamente 1 milhão de pacientes cegos, embora a prevalência oficial não passe de 250.000 pacientes em todo o mundo. O autor destaca a necessidade de melhor tratamento e acompanhamento dos pacientes e, conclama os oftalmologistas a tornarem-se mais perceptivos e se interessarem mais pelo tratamento das complicações oculares da hanseníase.

A sharp drop in the prevalence of leprosy occurred in the last three decades. However, the incidence has not decreased at the same rate. Three years after the World Health Organization last deadline for leprosy control, patients considered healed still need special care for their incapacities and immunopathological reactions. Medical literature reffers blindness in 4 percent to 11 percent of studied patients and more than 20 percent with severe visual problems due to corneal exposure, bacillary invasion and hipersensibility. These mechanisms result in a population of nearly one million blind leprosy patients even though official prevalence accounts no more than 250,000 patients worldwide. The author calls for better patients management and follow-up and urges ophthalmologists to become more aware and interested in the treatment of the ocular complications of leprosy.

Toxoplasmose adquirida ganglionar associada á uveíte anterior granulomatosa sem retinocoroidite / Ganglionar acquired toxoplasmosis associated with granulomatous anterior uveites without retinochoroiditis

Os autores relatam um caso de toxoplasmose ganglionar associada com uveíte anterior granulomatosa sem lesäo retiniana e tentam, neste estudo, explicar a fisiopatologia deste achado. É a primeira publicaçäo sobrea presença cancomitante de toxoplasmose ganglionar com iridocicle granulomatosa sem retinocoroidite em paciente imunocompatente.

Ciclite heterocrômica de Fuchs: associaçäo entre corpúsculos de Russel e imunoglobulinas / Fuchs heterochronic cyclitis: association between Russel corpuscles and immunoglobulins

Descrevemos o caso de uma paciente com ciclíte heterocrômica de Kushs, que apresenta corpúsculos de Russel sobre a superfície anterior da íris, e na qual detectamos níveis elevados de imunoglobulinas plasmáticas e no humor aquoso.

Why go endocapsular?

A prospective randomized clinical trial was carried out to compare the intercapsular or the endocapsular technique of IOL insertion and conventional posterior chamber IOL insertion after can opener capsulotomy. Age and sex matched groups of 76 patients each underwent surgery by the two techniques. The corneal and the uveal reaction was evaluated on the first day after the surgery and specular counts were done at six weeks. Though the difference between the two groups was not statistically significant, a trend in favour of intercapsular technique emerged strongly.

Clinico-pathologic correlates in Fuch's heterochromic iridiocyclitis--an iris angiographic study.

Iris Angiography in a case of Fuchs' heterochromic iridocyclitis (FHI) is described. The finding of iris angiography and hylainzed iris vessels on histopathology suggested ischemic etiology of FHI. This is the first report on Iris Angiography in a pigmented eye with Fuchs' heterochromic iridocyclitis.

Heterochromia iridium following central retinal vein occlusion

A 58-year-old woman developed a unique brownish discoloration of the iris, presumed to be hematogenous in origin, a few months after central retinal vein occlusion in her right eye. Apparently this heterochromia iridum, with the right iris brown and the left iris blue, was because of the severe retinal and vitreous hemorrhages that ensued the central retinal vein occlusion. There was no neovascularization of the discolored iris and no intraocular metallic foreign body in the blind left eye
