ABSTRACT
@#Visual loss after non-ocular surgery(VLNOS)includes postoperative visual loss and perioperative visual loss after non-ocular surgery. The former accident consists of the blindness during a surgery or after a surgery, and the latter accident shows the acute visual loss in perioperative period. VLNOS can be appeared in a prone spinal surgery, cardiopulmonary bypass surgery, head and neck surgery, and facial micro-plastic injection treatment, which is a rare, extremely serious complication. VLNOS is divided into predictable and unpredictable condition. Doctors of related subjects have pay attention to VLNOS, and begin to study the possible reasons, and take positive precautions.
ABSTRACT
Objective:To study the pathogenesis and the risk factors of eye injury after non-ocular surgery in the patients underwent general anesthesia, and to provide the reference for its prevention, diagnosis and treatment.Methods:The clinical materials of two patients with eye injury after non-ocular surgery underwent general anesthesia were analyzed and the related literatures were reviewed.Results:A young woman patient underwent laparoscopic hysterectomy with general anesthesia while positioned Trendelenburg, the eyes were being closed naturally without protection, and corneal abrasion of both eyes occurred after operation.The lesion had completely resolved with no sequelae after treatment.An old man underwent cervical posterior laminoplasty with general anesthesia in prone position developed ischemic optic neuropathy (ION) after operation.The vision of the patients partly recovered after symptomatic treatment.Conclusion:Corneal abrasion is the most frequent ophthalmologic complication during general anesthesia, most of the patients have good prognosis.Postoperative visual loss (POVL) is the most severe ophthalmologic complication without effective treatment available, the delicate reasons and mechanisms are not totally clear, prevention outweighs treatment.

Methods: The clinical materials of two patients with eye injury after non-ocular surgery underwent general anesthesia were analyzed and the related literatures were reviewed. Results: A young woman patient underwent laparoscopic hysterectomy with general anesthesia while positioned Trendelenburg, the eyes were being closed naturally without protection, and corneal abrasion of both eyes occurred after operation. The lesion had completely resolved with no sequelae after treatment. An old man underwent cervical posterior laminoplasty with general anesthesia in prone position developed ischemic optic neuropathy (ION) after operation. The vision of the patients partly recovered after symptomatic treatment. Conclusion: Corneal abrasion is the most frequent ophthalmologic complication during general anesthesia, most of the patients have good prognosis. Postoperative visual loss (POVL) is the most severe ophthalmologic complication without effective treatment available, the delicate reasons and mechanisms are not totally clear, prevention outweighs treatment.
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.

We report a case of a 15‑year‑old boy who presented with profound visual loss and complete ophthalmoplegia after an uneventful spinal surgery for removal of cervical osteoblastoma. Postoperative visual loss following nonocular surgery is, fortunately rare, yet a devastating complication. The most common cause is ischemic optic neuropathy, but it can also be due to central retinal occlusion or cortical blindness. Visual loss in conjunction with ophthalmoplegia is rarely seen, and there are very few reports in the literature. We also review the related literature and highlight the mechanism and preventive measures.
ABSTRACT
Postoperative visual loss (POVL) after non-ophthalmic surgery is rare, with a reported incidence ranging from 0.013 to 0.2%. Most perioperative visual loss is associated with spine operations and cardiac bypass procedures. The most common cause of POVL is ischemic optic neuropathy. However, there are no previous reports of postoperative visual loss after laparoscopic appendectomy. A 43-year-old female with no underlying disease underwent laparoscopic appendectomy; the operation was completed in one hour and her blood pressure was stable during the perioperative period. In the post-anesthetic care unit, the patient complained of nausea and headache, but she did not complain of any unusual visual symptoms. Approximately one hour after arriving at the ward, the patient complained of visual disturbance. Neurologic examination revealed left homonymous hemianopsia, and subarachnoid hemorrhage and intracerebral hemorrhage were found in the occipital area on brain MRI.
