ABSTRACT

ABSTRACT Vitreopapillary traction is an uncommon condition characterized by strong adhesion and the traction of the posterior hyaloid onto the optic disc and peripapillary retina, leading to optic disc elevation and visual loss. An 85-year-old man presented with a 6-month history of slow, progressive visual loss in the left eye along with optic disc edema. Swept-source optical coherence tomography B-scans revealed circumpapillary anterior-posterior persistent traction of dense vitreous strands onto the optic disc. Visual field examination demonstrated mild, generalized, diffuse sensitivity loss and blind-spot enlargement. A 25-gauge posterior vitrectomy was performed with posterior hyaloid separation from the optic disc, resulting in significant anatomical and visual improvement. In conclusion, swept-source optical coherence tomography aids in understanding the mechanism underlying visual loss in vitreopapillary traction. Moreover, posterior vitrectomy can effectively promote anatomical and visual improvements in these cases.


RESUMO A tração vitreopapilar é uma condição incomum caracterizada por forte adesão e tração da hialoide posterior no disco óptico e retina peripapilar, levando à elevação do disco óptico e à perda visual. Um homem de 85 anos apresentou uma história de 6 meses de perda visual lenta e progressiva no olho esquerdo, juntamente com edema do disco óptico. A tomografia de coerência óptica por fonte de varredura revelou tração persistente ântero-posterior peripapilar com traves vítreas densas sobre o disco óptico. Exame de campo visual demonstrou perda de sensibilidade difusa, generalizada, leve e aumento do ponto cego. Uma vitrectomia posterior de calibre 25 foi realizada com separação hialóide posterior do disco óptico, resultando em melhora anatômica e visual significativa. Em conclusão, a tomografia de coerência óptica por fonte de varredura auxilia na compreensão do mecanismo subjacente à perda visual na síndrome de tração vitreopapilar. Além disso, a vitrectomia posterior pode efetivamente promover melhorias visuais e anatômicas nesses casos.

ABSTRACT

ABSTRACT Purpose: To evaluate ophthalmic ultrasonographic findings associated with active ocular toxoplasmosis. Methods: Forty-seven eyes with active ocular toxoplasmosis in 47 patients were subjected to ocular ultrasonography using the transpalpebral technique (10-MHz transducer) and fundus photography. Patient medical records were retrospectively reviewed. Results: Ocular ultrasonography revealed vitritis, posterior vitreous detachment, retinal wall thickening, and non-rhegmatogenous retinal detachment in 47 (100%), 36 [76.6%; partial in 12 (25.5%) and total in 23 (48.9%)], 12 (25.5%), and 5 eyes (10.6%). Thirty-five of the 36 eyes with posterior vitreous detachment (97.2%) exhibited posterior hyaloid thickening; moreover, adhesion to the exudative lesion and vitreoschisis were observed in 4 (11.1%) and 12 eyes (25.5%), respectively. Ultrasonography detected the location of the exudative focus in 12 eyes (25.5%). Conclusion: Ultrasonography is helpful for detecting important intraocular findings of acute ocular toxoplasmosis that can be hindered by medial opacity or posterior synechiae.


RESUMO Objetivo: Avaliar os achados da ultrassonografia na toxoplasmose ocular ativa. Métodos: Quarenta e sete olhos com toxoplasmose ocular ativa em 47 pacientes foram submetidos à ultrassonografia ocular pela técnica transpalpebral (transdutor de 10 MHz) e fundo de olho. Os prontuários médicos foram revistos retrospectivamente. Resultados: A ultrassonografia ocular revelou vitreíte, descolamento vítreo posterior, espessamento da parede da retina e descolamento de retina não regmatogênico em 47 (100%), 36 [76,6%; parcial em 12 (25,5%) e total em 23 (48,9%)], 12 (25,5%) e 5 olhos (10,6%). Trinta e cinco dos 36 olhos com descolamento vítreo posterior (97,2%) exibiram espessamento hialoide posterior; além disso, a adesão à lesão exsudativa e vitreosquise foi observada em 4 (11,1%) e 12 (25,5%), respectivamente. A ultrassonografia detectou a localização do foco exsudativo em 12 olhos (25,5%). Conclusão: A ultrassonografia é útil na detecção de importantes achados intra-oculares de toxoplasmose ocular aguda que podem ser prejudicados pela opacidade medial ou sinéquia posterior.

ABSTRACT

ABSTRACT This study reports the first case of intravitreal angiostrongyliasis in South America treated with posterior worm removal via pars plana vitrectomy. This was a retrospective, observational case study. Data from medical charts, wide-field digital imaging, ocular ultrasound, and visual evoked potential studies were reviewed. A 20-month-old boy presented with eosinophilic meningitis and right eye exotropia. Polymerase chain reaction analysis of the cerebrospinal fluid showed a positive result for Angiostrongylus cantonensis. Fundus examination revealed a pale optic disc, subretinal tracks, vitreous opacities, peripheral tractional retinal detachment, and a dead worm in the vitreous cavity. The patient underwent pars plana vitrectomy with worm removal. This case report illustrates the first case of intravitreal angiostrongyliasis in South America, possibly related to the uncontrolled spread of an exotic invasive species of snail.


RESUMO O objetivo deste estudo foi relatar o primeiro caso na América do Sul de angiostrongilíase intravítrea tratada com vitrectomia posterior via pars plana e remoção do verme. Este foi um relato de caso observacional. O prontuário médico, sistema de imagem digital de campo amplo, ultrassonografia ocular, e potenciais evocados visuais foram revistos. Um menino de 1 ano e 8 meses de idade manifestou meningite eosinofílica e exotropia olho direito. A análise de PCR do liquor foi positiva para Angiostrongylus cantonensis. O exame de fundo de olho revelou disco óptico pálido, faixas sub-retinianas, opacidades vítreas, descolamento de retina tracional periférico e um verme morto no vítreo. O paciente foi submetido a vitrectomia posterior via pars plana com a remoção do verme. Concluindo, este é o primeiro relato de caso de angiostrongilíase intravítrea na América do Sul, possivelmente relacionado com a disseminação de uma espécie de lesma exótica neste continente.

ABSTRACT

Purpose: To report a case of bilateral vitritis originated from Primary Central Nervous System Lymphoma. Diagnosis was made from a careful history taking and confirmed with vitrectomy. Case report: 65-year-old Vietnamese male had one month of progressive blurred vision in both eyes without other eye complaint. History revealed that about one year previously, he was diagnosed with primary diffuse large B cell lymphoma. He was treated with chemotherapy of Methotrexate 3.5 g/m2and cytarabine 2 mg/m2, and a whole brain radiation therapy. There was a complete remission after the therapy. Fundus of both eyes was partly obscured by cells mainly in the posterior vitreous. Sequential bilateral vitrectomies were done on 5/1/17 and 7/17/17 without complication. The vitreous sample from the first eye having vitrectomy was sent for study which demonstrated large B cell lymphoma. Post-operative vision improved to 20/25 both eye without the complaint of hazy vision. Conclusion: Good history taking assisted in the diagnosis of intraocular lymphoma in this case with bilateral vitritis. However, bilateral vitrectomy restored the vision and further confirmed the diagnosis of lymphoma for future follow up care


Objetivo: Reportar un caso de vitritis bilateral originada por un Linfoma del Sistema Nervioso Central Primario. El diagnóstico se realizó a partir de una cuidadosa historia clínica y confirmada con vitrectomía. Reporte de caso: Varón vietnamita de 65 años con un mes de visión borrosa progresiva en ambos ojos sin otra afección ocular. La historia reveló que hace aproximadamente un año, se le diagnosticó un linfoma difuso primario de células B grandes. Fue tratado con quimioterapia con Methotrexate 3.5 g/m2 y citarabina 2 mg/m2 y una radioterapia cerebral completa. Hubo una remisión completa después de la terapia. El fondo de ambos ojos estaba parcialmente oscurecido por las células, principalmente en el vítreo posterior. Las vitrectomías bilaterales secuenciales se realizaron el 5/1/17 y el 17/7/17 sin complicaciones. La muestra vítrea del primer ojo sometida a vitrectomía fue enviada a un estudio que demostró linfoma de células B grandes. La visión postoperatoria mejoró a 20/25 ambos ojos sin la queja de la visión borrosa. Conclusión: una buena historia clínica fue útil en el diagnóstico de linfoma intraocular en este caso con vitritis bilateral. Sin embargo, la vitrectomía bilateral restauró la visión y confirmó aún más el diagnóstico de linfoma para el cuidado de seguimiento futuro.

ABSTRACT

A 34-year-old male patient was referred to us as a case of non-resolving suprachoroidal hemorrhage. History revealed decrease in right eye vision following trauma to forehead. B scan ultrasonography (USG) of the right eye showed a high-reflective structure indenting the globe. It turned out to be an inferiorly displaced fracture fragment from the orbital roof on computerized tomography (CT) scan. The choroidal elevation disappeared after open reduction of the fracture fragment and patient had good recovery of vision. USG and CT scan were helpful in the diagnosis and management of this case.
