ABSTRACT An 81-year-old male patient with systemic hypertension, diabetes mellitus, and dyslipidemia presented with sudden visual acuity loss in the right eye (RE) due to a branch retinal artery occlusion (BRAO) associated with macular edema. Despite treatment with intravitreal bevacizumab, the patient developed persistent inner retinal ischemia, evidenced by optical coherence tomography (OCT) findings of retinal inner plexiform layer (RIPL) alterations. Years later, he suffered an ischemic stroke, highlighting the association between retinal ischemic changes and systemic vascular risk. This […]

ABSTRACT The global cosmetic industry growth and the desire for aesthetics and rejuvenation have increased the aesthetic procedures. Autologous fat is the most common and most serious type of filling related to iatrogenic blindness. Iatrogenic occlusion of the ophthalmic artery is a rare but devastating complication of facial filler injections. Although several treatments have been reported and proposed, to date there is no proven efficacy. In identifying central retinal artery occlusion, timing is crucial to the patient’s visual prognosis. The […]

ABSTRACT This case series describes four patients who presented with retinal and optic nerve vascular occlusions after administration of different COVID-19 vaccines. The first patient received the ChAdOx1 nCoV-19 vaccine (AZD1222; Oxford/AstraZeneca) and 42 days later developed central retinal artery occlusion. The second patient developed a painless visual impairment in the left eye and was diagnosed with anterior ischemic optic neuropathy 6 days after receiving the Sinovac-CoronaVac vaccine. The third patient presented with the same condition 22 days after receiving […]

ABSTRACT Ophthalmologic complications of nonocular surgeries are rare events, but can lead to irreversible conditions of low visual acuity. They are often associated with spine, heart and neck surgery, however they can occur after procedures on other systems. The main local causes are ischemic optic neuropathies, vascular occlusions, cortical lesions, and acute angle-closure glaucoma. We report two cases of sudden low visual acuity secondary to vascular occlusions after gastrointestinal procedures. In the first case, a 57-year-old patient electively admitted for […]

We here in report the case of a patient subjected to cataract surgery through phacoemulsification under local anesthetic block, without intra-operative complications. The patient presented important visual impairment in the first post-operative day. Fundoscopy showed pallor resembling cherry-red spots at the macula. Fluorescein angiography did not depict signs of vascular occlusion and the spectral-domain optical coherence tomography showed increased reflectivity in the inner layers of the retina, thus suggesting local thickening and edema. The current case led to the diagnostic […]

Relatamos um caso de um paciente submetido a facectomia por facoemulsificação sob bloqueio anestésico peribulbar, sem intercorrências per-operatória, que apresentou no primeiro dia de pós-operatório baixa visual significativa. À fundoscopia observou-se palidez em aspecto de mácula em cereja. A angiofluoresceinografia não demonstrou sinais de oclusão vascular e a tomografia de coerência óptica mostrou aumento da refletividade das camadas internas da retina, sugerindo espessamento e edema local. No caso descrito foi aventada hipótese diagnóstica de oclusão arterial retiniana transitória.

Susac’s syndrome is a rare disease attribuited to a microangiopathy involving the arterioles of the cochlea, retina and brain. Encefalopathy, hearing loss, and visual deficits are the hallmarks of the disease. Visual loss is due to multiple, recurrent branch arterial retinal occlusions. We report a case of a 20-year-old women with Susac syndrome presented with peripheral vestibular syndrome, hearing loss, ataxia, vertigo, and vision loss due occlusion of the retinal branch artery.

Síndrome de Susac é uma microangiopatia rara que afeta as arteríolas da cóclea, retina e encéfalo. Encefalopatia, perda auditiva e baixa da acuidade visual formam a tríade clássica da doença. A baixa de acuidade visual ocorre devido a múltiplas e recorrentes oclusões de ramo arterial da retina. Relatamos o caso de uma paciente de 20 anos com síndrome de Susac apresentando síndrome vestibular periférica, perda auditiva, vertigem, ataxia e baixa da acuidade visual por oclusão de ramo arterial de retina.
