Etiological Analysis of 248 Cases of Oculomotor Nerve Palsy

Objective:To explore the main causes of oculomotor nerve palsy,providing a reference for clinical diagnosis and treatment.Methods:A total of 248 patients with oculomotor nerve palsy treated in the hospital from January 2016 to January 2018 were selected,and their causes and treatments were summarized.Results:This study found that the main causes of oculomotor nerve palsy were intracranial aneurysms,brain stem lesions,and brain inflammation.A few cases were due to viral infections and congenital oculomotor nerve palsy,while some patients had unknown causes.After treatment in our hospital,most patients experienced relief,although 12 patients died.Conclusion:The etiology of oculomotor nerve palsy is complex,and choosing appropriate drugs during treatment is challenging.Timely identification of the cause is an effective method for treatment.

Clinical Effect Analysis of Posterior Chamber Intraocular Lens Implantation for Correcting High Myopia and Astigmatism

Objective:To explore the corrective effect of posterior chamber intraocular lens implantation with phakic eyes in the treatment of high myopia and astigmatism.Methods:From May 2023,the hospital began to collect the case data of diagnosis and treatment of high myopia and astigmatism.By May 2024,310 cases were included,all of which were treated with posterior chamber intraocular lens implantation.The visual acuity,astigmatism and axial position of the intraocular lens were observed before and after treatment.Results:At different time points after the operation,the patient’s vision was significantly improved compared with that before the operation(P<0.05),and the vision level was equal to or greater than the best-corrected vision before the operation.At different time points after the operation,the average rotation of the intraocular lens was less than 5 degrees.Astigmatism was significantly lower than that before the operation(P<0.05).After the operation,the intraocular pressure increased in 11 cases,accounting for 3.55%,with no adverse complications such as lens turbidity,glare and obvious halo occurring.Conclusion:The posterior chamber intraocular lens implantation with phakic eyes has an ideal correction effect in the treatment of high myopia and astigmatism,which can effectively improve the vision level of patients and reduce the degree of astigmatism,and has high effectiveness and safety.
