Optical coherence tomography angiography findings in patients with Alport syndrome
Conclusions: In patients with Alport syndrome, the inner retinal layers suffer changes due to type IV collagen mutations. Optical coherence tomography angiography makes it possible to visualize and document thes e findings, making it a useful tool in the detection of early retinal findings associated with Alport syndrome.RESUMO Objetivos: Descrever os achados na angiografia por tomografia de coer ência óptica associada à síndrome de Alport. Métodos: Estudo descritivo de um serviço de referência em Oftalmologia (Hospital Evangélico de Vila Velha, Brasil). Os pacientes diagnosticados com síndrome de Alport, foram ...

Characterization and distribution of viridans group streptococci isolated from infectious endophthalmitis and keratitis
Conclusions: The distribution of alpha-hemolytic streptococci in ocular infections suggested the presence of a species-specific tissue tropism. The prognoses of patients with ocular streptococcal infections were highly unfavorable, and antibiotic resistance did not contribute to the unfavorable clinical progressions and poor outcomes.RESUMO Objetivo: O objetivo deste estudo foi caracterizar os estreptococos alfa-hemol íticos isolados de endoftalmite infecciosa e ceratite e determinar sua distribuição. Métodos: A amostra incluiu 27 e 35 isolados não-duplicados de estreptococos alfa-hemolíticos recuperados de pacient...

The Canabrava Ring, an open ring-shaped pupil expander for cataract surgery associated with iris colobomata: a case report
In this report, we describe a new pupil expander device that was used to obtain adequate pupil dilation and centering in a patient with an iris coloboma. Specifically, we describe the case of a patient with an iris coloboma; a Malyugin ring was inserted to facilitate dilation during phacoemulsifi ­cation surgery. One of the scrolls did not engage which resulted in an uneven distribution of forces and an eccentric pupil. A Canabrava Ring was then implanted that promoted effective pupillary dilation and remained stable and effective throughout the surgical procedure.RESUMO Neste relato, descrevemos um novo dispositivo expan...

Descemet’s membrane endothelial keratoplasty for acute corneal hydrops: a case report
ABSTRACT Here, we describe the result of a Descemet ’ s membrane endothelial keratoplasty for acute corneal hydrops in a 45-year-old female with keratoconus, who presented with severe visual loss in her OS. The patient ’ s best-corrected visual acuity was 20/80 in the right eye and hand motion in the OS. Slit-lamp examination revealed an extensive tear of the Descemet ’ s membrane and stromal corneal edema in the OS. We opted for Descemet membrane endothelial keratoplasty. Twelve months postoperatively, the patient had a best-corrected visual acuity of 20/50 in the OS.RESUMO Trata-se de uma paciente do sexo feminino,...

Solitary circumscribed neuroma of the conjunctiva: Differential diagnosis from neurofibroma is a must?
ABSTRACT A 42-year-old male presented with a 4-week history of a mass in the right inferior palpebral conjunctiva close to the punctum. An excisional biopsy of the lesion and histopathological examination revealed that the mass was composed of Schwann cells with thin conical nuclei, fine chromatin, and unnoticeable nucleoli. Immunohistochemically, the spindle cells were diffusely and strongly positive for S100 protein. Neurofilament immunostaining was also positive, which highlighted axons. In light of these findings, the tumor was diagnosed as solitary circumscribed neuroma. A comprehensive evaluation for multiple endocri...

We describe here the surgical management of a 16-year-old boy who presented with complex strabismus secondary to hypoplasia of the third cranial nerve and aberrant innervation of the upper ipsilateral eyelid.RESUMO Os dist úrbios de inervação craniana congênita en­globam um grupo de síndromes associadas a estrabismos complexos, que se apresentam como oftalmoplegia congênita e não progressiva e são frequentemente herdadas. Os defeitos dos genes estão associados a erros no desenvolvimento ou direcionamento axo nal dos motoneurônios, e erros no direcionamento axonal para os músculos extraoculares. Este caso descre...

Ocular blood flow and choroidal thickness changes after carotid artery stenting
Conclusions: In patients with carotid artery stenosis, the subfoveal choroid is thinner than that in healthy controls. The subfoveal choroidal thickness increases after carotid artery stenting. Carotid artery stenting treatment increases the blood flow to the posterior ciliary artery, and the preprocedural subfoveal choroidal thickness may be a good predictor of the postprocedural peak systolic velocity of the posterior ciliary artery.RESUMO Objetivos: Avaliar altera ções no fluxo sanguíneo ocular e na espessura da coroide subfoveal em pacientes com estenose sintomática da artéria carótida, após implante de stent n...

Optical coherence tomography detection of changes in inner retinal and choroidal thicknesses in patients with early retinitis pigmentosa
Conclusions: The choroid was mildly affected in our patients with early retinitis pigmentosa. The tendency toward significance in the inner retina was possibly caused by a good visual acuity.RESUMO Objetivo: Avaliar as espessuras internas da retina e da coroide em pacientes com retinite pigmentosa precoce. M étodos: Foram analisadas imagens de tomografia de coerência óptica de domínio espectral de 35 pacientes com retinite pigmentosa e 40 indivíduos saudáveis. Medimos a espessura do complexo de células maculares e ganglionares. Realizamos medições da espessura da coroide na região subfoveal e a 500 mm, 1000 mm ...
