Choroidal osteoma with choroidal excavation and associated neovascular membrane: An OCT-angiography study.

2017

Abstract Clinical case A case is presented of a unilateral choroidal osteoma with choroidal excavation and associated neovascular membrane that was studied using OCT-angiography. The OCT and OCT-angiography revealed an area of choroidal excavation and an active neovascular membrane. Three doses of aflibercept were administered to the patient, which stabilized the neovascularisation. Discussion OCT-angiography was used to analyze the morphology of the superficial vascular network of the osteoma, as well as to monitor the evolution of the neovascular membrane.

Correlation Between Ischemic Retinal Accidents and Radial Peripapillary Capillaries in the Optic Nerve Using Optical Coherence Tomographic Angiograph…

2017

Background: Perfusion of the optic nerve has been widely studied using fluorescein angiography (FAG), which is currently regarded as the criterion standard. However, FAG has adverse effects associated with intravenous contrast administration and is limited in its capacity to characterize and stratify the different vascular layers of the optic nerve and retina. The use of new imaging techniques, such as optical coherence tomographic angiography (Angio-OCT), is therefore important. Aim: A qualitative description is made of the vascular layers of the optic nerve and of how vascular events affect radial peripapillary capillaries (RPC). Two patients with central retinal artery occlusion (CRAO), …

Primary multifocal anaplastic large cell lymphoma with eyelid involvement: a case report

2019

ABSTRACT Ocular adnexal involvement in CD30+ lymphoproliferative disorders is rare. We report the case of a 73-year-old woman with a relapsing primary cutaneous anaplastic large cell lymphoma on her eyelid. A systemic extension study excluded extracutaneous involvement. Systemic chemotherapy resulted in an optimal response, with complete regression of the cutaneous lesions. There has been no recurrence during the 2 years of follow-up. RESUMO O acometimento ocular adicional nos distúrbios linfoproliferativos CD30+ é raro. Relatamos o caso de uma mulher de 73 anos com linfoma de grandes células anaplásicas primárias recidivantes em sua pálpebra. A avaliação sistêmica excluiu envolvimento extr…

Endoftalmitis de inicio tardío asociada a ampolla de filtración por Moraxella nonliquefaciens

2020

Resumen Las endoftalmitis asociadas a la ampolla de filtracion tras cirugia filtrante de glaucoma son poco frecuentes, de inicio tardio y la mayoria estan asociadas a una blebitis. Los agentes causales suelen ser estreptococos o bacterias gramnegativas. Existen pocos casos descritos en la literatura de endoftalmitis causada por Moraxella nonliquefaciens y la mayoria estan asociados a una blebitis tras cirugia filtrante de glaucoma. Presentamos el caso de una paciente de 90 anos con endoftalmitis en ojo derecho por Moraxella nonliquefaciens asociada a blebitis 10 anos despues de la cirugia de glaucoma. Tras el tratamiento, se observo la desaparicion de la blebitis 2 semanas despues y resoluc…

Osteoma de coroides con excavación coroidea y membrana neovascular asociada: estudio mediante angiografía-TCO

2018

Resumen Caso clinico Presentamos un caso de osteoma de coroides unilateral con excavacion coroidea y membrana neovascular asociada estudiado mediante angiografia-TCO. En TCO y angiografia-TCO se objetivo excavacion coroidea y una membrana neovascular coroidea activa. Se administraron tres dosis de aflibercept estabilizando la neovascularizacion coroidea. Discusion La angiografia-TCO permitio el analisis morfologico de la red vascular superficial del osteoma asi como el control evolutivo de la membrana neovascular.

Bilateral maculopathy after exposure to a laser pointer: Optical coherence tomography angiography findings.

2018

Abstract Case report A 36-year-old man went to the emergency department the day after exposure to a laser pointer. Funduscopy revealed dispersed macular pigment alterations, and optical coherence tomography showed a disruption of the retinal layers. The visual acuity was counting fingers in both eyes. Nine months later, optical coherence tomography angiography showed a rarefaction in the choriocapillaris vascular flow in the area of the laser injuries. Discussion The retinal layer mainly damaged by the laser injury was the retinal pigment epithelium. However, it is suggested that the laser injury could involve tissues beyond the retinal pigment epithelium, since a rarefaction of the chorioc…

Uveítis anterior aguda hipertensiva granulomatosa bilateral como efecto adverso a brimonidina tópica

2018

Abstract Clinical case The case concerns an 81-year-old woman on treatment with a topical fixed combination of timolol and brimonidine who was diagnosed in the Emergency Department with acute anterior granulomatous hypertensive uveitis. The patient responded favorably to the withdrawal of the eye drops without showing any subsequent relapse. Discussion Uveitis due to brimonidine is a rare adverse effect, but it must be known. Once the diagnosis is suspected, the effective treatment is the withdrawal of brimonidine, with or without the addition of topical corticosteroids to control inflammation depending on the severity of the condition. It is a process with an excellent prognosis.

Queratitis bacteriana por Moraxella nonliquefaciens

2020

Moraxella keratitis can lead to important complications. Moraxella nonliquefaciens(M. nonliquefaciens) has the worst prognosis. Only three cases of corneal infections due to M. nonliquefaciens have been published. The case is presented of a 79-year-old man with bullous keratopathy, recently affected with severe infectious keratitis. Dense, deep, and central stromal infiltrates and hyphaema were detected. After the identification of M. nonliquefaciens in the culture, and given the progression of the condition, the initial empirical treatment was modified to topical ciprofloxacin and ceftazidime in accordance with the antibiogram, combining oral ciprofloxacin and amoxicillin-clavulanate. Afte…

Nueve meses despues se evidencio en la angiografia mediante tomografia de coherencia optica una alteracion del flujo vascular coriocapilar en la zona lesionada por el laser. Discusion El laser afecta principalmente al epitelio pigmentario retiniano. Sin embargo, con este caso ponemos de manifiesto la posible afectacion mas alla del epitelio pigmentario retiniano, apareciendo …

Retinal detachment with spontaneous dialysis of the ora serrata in a 13-year-old child with neurofibromatosis type 1: a case report.

2020

A 13‑year‑old child diagnosed with neurofibromatosis type 1 who on a routine control presented with rhegmatogenous retinal detachment associated to dialysis of the ora serrata in the left eye (OS). There were no clinical signs or history of contuse ocular trauma. Neurofibromatosis produces alterations in fibroblasts of the cortex of the vitreous base. This results in deficient production of the collagen fibers that anchor the vitreous base to the pars plana and the peripheral neurosensory retina. Thus, suboptimal function of the fibroblasts explains spontaneous avulsion of the vitreous base. Such avulsion in turn is related to dialysis of the ora serrata.

Delayed-onset bleb-related endophthalmitis caused by Moraxella nonliquefaciens.

2020

Bleb-related endophthalmitis is rare and appears months or years after surgery. The causative agents are usually streptococci or gram-negative bacteria. There are few cases in the literature of endophthalmitis caused by Moraxella nonliquefaciens, and most are delayed-onset associated with blebitis after glaucoma filtration surgery. The case is presented of a 90-year-old patient with endophthalmitis in the right eye due to Moraxella nonliquefaciens associated with blebitis 10 years after glaucoma surgery. After treatment, disappearance of blebitis is observed 2weeks later and resolution of vitritis 29 days later, with recovery of vision to previous values (20/200). Endophthalmitis due to Mor…

ACUTE VISION LOSS AS THE ONLY SIGN OF LEUKEMIA RELAPSE.

2016

Purpose To report a case of unilateral exudative retinal detachment as the sole presentation of relapsing B-type lymphoblastic leukemia in a 35-year-old man after 3 years of remission. Methods Case report. Results A 35-year-old man in complete remission of high-risk type B acute lymphoblastic leukemia (ALL-B) presented with acute vision loss in his left eye. Exudative retinal detachment was diagnosed at initial evaluation. Hematological and ocular studies were performed. Although there was no evidence of blood, cerebrospinal fluid, or bone marrow disease relapse, transvitreal retinochoroidal cytology identified the infiltration of lymphoblastic leukemic B cells with t(12:21) translocation a…
