ABSTRACT

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 colon reconstruction after Hartmann's colostomy, progressed with intra- and postoperative complications and required subsequent complementary surgeries. Once month later he presented with sudden bilateral low visual acuity, painless and non-altitudinal, and was diagnosed as papillophlebitis, which resolved spontaneously with the progression of the condition. The second case, a 69-year-old patient with no comorbidities underwent rectal resection due to suspected malignant tumor, and progressed on the third postoperative day, with pain and bilateral low visual acuity secondary to acute angle-closure glaucoma, and branch retinal artery occlusion in right eye; treated with iridotomy and ocular hypotensive eye drops, with only slight recovery of vision. The article aims to discuss the etiological mechanisms of the reported conditions and present a literature review.


RESUMO Complicações oftalmológicas de cirurgias não oculares são raras, mas podem levar a condições irreversíveis de baixa acuidade visual. Em geral são associadas à cirurgia de coluna, coração ou pescoço, mas podem ocorrer após procedimentos em outros sistemas. As principais causas são neuropatias ópticas isquêmicas, oclusões vasculares, lesões corticais, e glaucoma agudo de ângulo fechado. Relatamos dois casos de baixa acuidade visual súbita, secundária a oclusões vasculares, após procedimentos cirúrgicos gastrointestinais. No primeiro caso, um paciente de 57 anos foi internado de forma eletiva para reconstrução do cólon após colostomia de Hartmann. Evoluiu com complicações nos períodos intra- e pós-operatório, e necessitou de outras cirurgias complementares. Um mês depois apresentou baixa acuidade visual bilateral súbita, indolor e não altitudinal, e foi diagnosticado como papiloflebite, com resolução espontânea na evolução. O segundo caso, uma paciente de 69 anos, sem comorbidades, foi submetida à ressecção do reto por suspeita de tumor maligno e, no terceiro dia de pós-operatório, evoluiu com dor e baixa acuidade visual bilateral, secundária a glaucoma agudo de ângulo fechado, e oclusão de ramo da artéria retiniana no olho direito; tratada com iridotomia e colírios hipotensores, com recuperação parcial da visão. O objetivo do artigo é discutir os mecanismos etiológicos das doenças relatadas, e apresentar uma revisão da literatura.

ABSTRACT

ABSTRACT 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 hypothesis of transient retinal arterial occlusion.


RESUMO 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.

ABSTRACT

Abstract Postoperative visual loss is a rare and devastating complication. The estimated incidence is 0.01-1% after non ocular surgery. It has been reported after spine, cardiac and head and neck surgeries. We report a patient who was operated for cervical laminectomy in prone position and complained of loss of vision in one eye postoperatively. He was thoroughly investigated after visual loss. The case was diagnosed as central retinal artery occlusion (CRAO) of the left eye. Here we consider the potential etiological factors causing this unilateral loss of vision and try to suggest strategies to reduce the incidence of the complication in spinal surgery.


Resumo A perda visual pós-operatória é uma complicação rara e devastadora. A incidência estimada é de 0,01-1% após cirurgia não oftalmológica. Há relatos de sua ocorrência após cirurgias da coluna, cardíaca e de cabeça e pescoço. Relatamos o caso de um paciente submetido à laminectomia cervical em pronação que se queixou de perda de visão em um dos olhos no pós-operatório. O paciente foi profundamente investigado após a perda visual. O caso foi diagnosticado como oclusão da artéria central da retina (CRAO) do olho esquerdo. Aqui consideramos os potenciais fatores etiológicos que causam essa perda unilateral da visão e tentamos sugerir estratégias para reduzir a incidência dessa complicação em cirurgia de coluna vertebral.

ABSTRACT

ABSTRACT A 22-year-old man complained of low visual acuity and pain in his left eye for five days. His ophthalmological examination revealed 2+ anterior chamber reaction and a white, poorly defined retinal lesion at the proximal portion of the inferotemporal vascular arcade. There were retinal hemorrhages in the inferotemporal region extending to the retinal periphery. In addition, venous dilation, increased tortuosity, and ischemic retinal whitening along the inferotemporal vascular arcade were also observed. A proper systemic work-up was performed, and the patient was diagnosed with ocular toxoplasmosis. He was treated with an anti-toxoplasma medication, and his condition slowly improved. Inferior macular inner and middle retinal atrophy could be observed on optical coherence tomography as a sequela of ischemic injury. To our knowledge, this is the first report of combined retinal branch vein and artery occlusion in toxoplasmosis resulting in a striking and unusual macular appearance.


RESUMO Um paciente do sexo masculino, com 22 anos de idade, queixou-se de redução da acuidade visual no olho esquerdo por 5 dias. O exame oftalmológico mostrou reação de câmara anterior 2+ e uma lesão retiniana esbranquiçada, pouco definida, na porção proximal da arcada vascular temporal inferior. Foram observadas hemorragias retinianas na região temporal inferior estendendo-se à periferia, assim como ingurgitamento venoso, aumento da tortuosidade e palidez isquêmica da retina no mesmo quadrante. Exames laboratoriais corroboraram o diagnóstico de toxoplasmose ocular. O paciente melhorou lentamente após tratamento apropriado. Foi evidenciada atrofia da retina macular inferior interna e média à tomografia de coerência óptica, como sequela da isquemia retiniana. Para nosso conhecimento, este é o primeiro relato de oclusão retiniana combinada de ramo arterial e venoso em toxoplasmose ocular, levando a um aspecto fundoscópico atípico e peculiar.

ABSTRACT

RESUMO A poliangeíte microscópica é uma vasculite necrotizante sistêmica que acomete arteríolas, capilares e vênulas, mas também pode atingir pequenas e médias artérias. É considerada uma doença rara, idiopática e autoimune. Diversas anormalidades oculares e sistêmicas estão associadas às oclusões arteriais retinianas. Dentre as doenças vasculares do colágeno, a literatura cita como possíveis causas de obstrução das artérias retinianas o lúpus eritematoso sistêmico, a poliarterite nodosa, a arterite de células gigantes, a granulomatose de Wegener e a granulomatose linfóide de Liebow. Até o presente momento, não se encontrou na literatura relatos da associação de casos de oclusão arterial retinana associados à PAM. Os autores relatam o caso de um paciente com poliangeíte microscópica que apresentou comprometimento renal importante e oclusão da artéria central da retina unilateral. Atenta-se para a inclusão de pesquisa da PAM, através do p-ANCA, na avaliação de possível origem sistêmica em pacientes acometidos por oclusão arterial retiniana.


ABSTRACT The microscopic polyangiitis is a systemic necrotizing vasculitis that affects arterioles, capillaries and venules, but can also reach small and medium-sized arteries. It is considered a rare disease, idiopathic in nature but clearly autoimmune. Several ocular and systemic abnormalities are associated with retinal arterial occlusions. Among the collagen vascular diseases, the literature cited as possible causes of retinal artery obstruction lupus erythematosus, polyarteritis nodosa, giant cell arteritis, Wegener’s granulomatosis and lymphoid Liebow. Until now, there were no reports in the literature of the association of cases of arterial occlusion retinana associated with PAM. The authors report a case of a 53 years old patient diagnosed with microscopic polyangiitis who presented with important renal artery occlusion and associated unilateral central retinal artery occlusion. An extended systemic evaluation of patients presenting with central retinal artery occlusion should include research of PAM through analysis op p-ANCA.

ABSTRACT

Cosmetic facial filler-related ophthalmic artery occlusion is rare but is a devastating complication, while the exact pathophysiology is still elusive. Cerebral angiography provides more detailed information on blood flow of ophthalmic artery as well as surrounding orbital area which cannot be covered by fundus fluorescein angiography. This study aimed to evaluate cerebral angiographic features of cosmetic facial filler-related ophthalmic artery occlusion patients. We retrospectively reviewed cerebral angiography of 7 patients (4 hyaluronic acid [HA] and 3 autologous fat-injected cases) showing ophthalmic artery and its branches occlusion after cosmetic facial filler injections, and underwent intra-arterial thrombolysis. On selective ophthalmic artery angiograms, all fat-injected patients showed a large filling defect on the proximal ophthalmic artery, whereas the HA-injected patients showed occlusion of the distal branches of the ophthalmic artery. Three HA-injected patients revealed diminished distal runoff of the internal maxillary and facial arteries, which clinically corresponded with skin necrosis. However, all fat-injected patients and one HA-injected patient who were immediately treated with subcutaneous hyaluronidase injection showed preserved distal runoff of the internal maxillary and facial arteries and mild skin problems. The size difference between injected materials seems to be associated with different angiographic findings. Autologous fat is more prone to obstruct proximal part of ophthalmic artery, whereas HA obstructs distal branches. In addition, hydrophilic and volume-expansion property of HA might exacerbate blood flow on injected area, which is also related to skin necrosis. Intra-arterial thrombolysis has a limited role in reconstituting blood flow or regaining vision in cosmetic facial filler-associated ophthalmic artery occlusions.

ABSTRACT

Oclusão da artéria central da retina é uma doença comumente encontrada em pacientes idosos, mas pode também ser vista em crianças e adultos jovens. Nestes, as principais causas são anomalias cardíacas, sendo o forame oval patente o mais observado. O objetivo do trabalho é relatar o caso de um paciente jovem com oclusão da artéria central da retina apresentando persistência de forame oval e, também, salientar a importância de uma propedêutica detalhada nos casos de oclusões vasculares da retina.


Central retinal artery occlusion it’s a disease most encountered in older patients, however it can be seen in children and young persons. In this situation the principal causes are cardiac abnormalities, and the patent foramen ovale is the most observed. The purpose of this study is to report a case of central retinal artery occlusion in a young patient with patent foramen ovale and, also, describe the importance of a detailed management in cases of retinal vascular occlusions.

ABSTRACT

We report the case of a 24-year-old man presenting with sudden visual loss in the left eye from a central retinal artery occlusion. An extensive clinical investigation revealed no etiology. Three weeks later, however, the patient developed hearing loss followed by encephalopathy and multiple branch retinal artery occlusions in the right eye. Fluorescein angiography confirmed retinal vascular occlusions with no sign of vasculitis. The neurological examination revealed a diffuse encephalopathy while the MRI scan disclosed several small areas of infarcts in the brain. Bilateral sensorineural hearing loss was confirmed on audiometry. The patient was diagnosed with Susac syndrome and treated with methylprednisolone and cyclophosphamide, resulting in slight improvement and stabilization. This case shows that Susac syndrome may be diagnosed late due to the absence at onset of one or more of the symptoms of the classic triad (encephalopathy, multiple branch retinal artery occlusions and hearing loss). This case also serves to emphasize that Susac syndrome should be considered in the differential diagnosis of central retinal artery occlusion, even in apparently healthy young men.


Descrevemos um paciente de 24 anos, sexo masculino, que se apresentou com perda súbita da visão do olho esquerdo causado por oclusão da artéria central da retina. Ele foi submetido à investigação clínica detalhada sem encontrar uma causa. Três semanas depois, no entanto, desenvolveu surdez, encefalopatia e múltiplas oclusões de ramo arterial da retina no olho direito. Angiofluoresceinografia confirmou as oclusões de ramo arterial no OD e oclusão da artéria central da retina no OE, sem qualquer sinal de vascutile. O exame neurológico revelou encefalopatia difusa, enquanto que o estudo efetuado por ressonância nuclear magnética mostrou várias áreas de enfarte do cérebro e a audiometria demonstrou perda auditiva neurosensorial bilateral. A síndrome de Susac foi diagnosticada e tratamento com metilprednisolona e ciclofosfamida instituido com melhora discreta, seguida de estabilização clínica. Este caso é importante para chamar a atenção de que nem todos os três critérios diagnósticos (encefalopatia, oclusão de ramo arterial retiniano e surdez) para a síndrome de Susac precisam estar presentes de início, o que pode causar confusão diagnóstica. O diagnóstico deve portanto ser incluído no diferencial de oclusão da artéria central da retina mesmo quando ocorre em homem sem outros sintomas associados.

ABSTRACT

A 30-year-old patient presented at our outpatient department with complaints of severe loss of vision in both eyes following a head injury six days back. He also had a fracture at left side of the mandible and a few bruises over the left cheek. External ocular examination revealed subconjuctival hemorrhage in the left eye and bilateral sluggishly reacting pupils. Fundus examination showed white- out retina and a cherry red spot at the macula in both eyes. A clinical diagnosis of bilateral central retinal arterial obstruction (CRAO) was made which was later confirmed by fundus fluorescence angiography. Bilateral CRAO is a rare disease usually found in patients with cardiac embolic diseases, giant cell arteritis or systemic vascular inflammations. Our case is the second reported case in English literature of bilateral CRAO following head trauma.

ABSTRACT

A 48-year-old man presented following an episode of sudden onset simultaneous inferior altitudinal visual loss in his left eye and visual obscuration with shimmering in the inferonasal quadrant of the right eye. Clinical examination demonstrated left superior hemiretinal artery occlusion and an area of focal dynamic spasm along the right superior temporal branch retinal artery, the arteriolar spastic cycle was about 2 sec in duration. Hematological (including complete blood count, thrombophilia screen, vasculitic screen and serum magnesium), carotid, and cardiac investigations were normal. He was given acetazolamide 500 mg orally, timolol maleate 0.5% eye drops once daily and sublingual amyl-nitrate 0.8 mg, and maintained on felodipine 10 mg/day and aspirin 100 mg/day. The area of focal arteriolar spasm in the right eye resolved over two months. To our knowledge there are no prior reports of photographically documented dynamic focal retinal vascular spasm on a MEDLINE and PUBMED search.

ABSTRACT

A 27-year-old woman was referred by the neurologist for ophthalmic examination. She had a history of headache, visual loss in her right eye, four-limb paresthesia, and behavioral changes over the previous 10 months. The patient complained of tinnitus and hearing loss for two weeks. The patient was initially diagnosed with multiple sclerosis, but auditory and retinal involvement [small branch retinal artery occlusion in fluorescein angiography] raised the possibility of Susac's syndrome

ABSTRACT

An 82-year-old female presented with sudden painless decrease in vision in the right eye after awakening. She could see the “superior half” of her vision from the right eye only. On examination, best-corrected vision was 20/300 in the right eye and 20/30 in the left eye. The fundus in the right eye revealed recent superotemporal branch retinal artery occlusion (BRAO) with calcified plaque at the disc. Spectral domain optical coherence tomography (OCT) (OTI Ophthalmic Technologies, Inc.), revealed hyperreflectivity and increased thickness of the inner retinal layers of the superior compared to the inferior retina. Imaging at the optic disc revealed the blocked artery containing a highly reflective material. The high reflectivity of the material and underlying optical shadowing could be characterized as calcific emboli.

ABSTRACT

Amongst the clinical presentations of retinal artery occlusion, hemi-central retinal artery occlusion (Hemi-CRAO) is rarely described. This case series of four adults aged between 22 and 36 years attempts to describe the clinical profile, etiology and management of Hemi-CRAO. Case 1 had an artificial mitral valve implant. Polycythemia and malignant hypertension were noted in Case 2. The third patient had Leiden mutation while the fourth patient had Eisenmenger’s syndrome. Clinical examination and fundus fluorescein angiography revealed a bifurcated central retinal artery at emergence from the optic nerve head, in all cases. Color Doppler examination of the central retinal artery confirmed branching of the artery behind the lamina cribrosa. It is hypothesized that bifurcation of central retinal artery behind the lamina cribrosa may predispose these hemi-trunks to develop an acute occlusion if associated with underlying risk factors. The prognosis depends upon arterial recanalisation and etiology of the thromboembolic event.

ABSTRACT

A 23-year-old male patient with right nasal Juvenile Nasopharyngeal Angiofibroma (JNA) developed Central Retinal Artery Occlusion (CRAO) during embolization of the tumor using polyvinyl alcohol particles before endoscopic excision. Classic CRAO management was initiated by an ophthalmologist after 12 h. Retrospective evaluation of the angiograms revealed a tiny communication between the external carotid and ophthalmic arteries which had not been noticed before embolization. During endoscopic excision, the tumor was found to originate extraordinarily from midline structures. It was concluded that CRAO might be a rare complication of JNA embolization. Careful preoperative angiographic evaluations to detect communicating arteries and immediate ophthalmologic consultation in case of developing visual symptoms during the procedure are necessary.
