Background To analyze the etiology of optic disc swelling (ODS) and compare the clinical features between non-arteritic anterior ischemic optic neuropathy (NA-AION) and optic neuritis (ON) at our center from January 2019 to January 2020. Methodology Clinical records of all patients who presented with ODS between January 2019 and January 2020 were reviewed. The collected data were analyzed using IBM SPSS Statistics for Windows (Version 23.0, IBM Corp., Armonk, NY, USA). Results A total of 70 eyes among 47 patients were included in this review. There were 24 patients (51%) who had unilateral ODS, while 23 patients (49.0%) had bilateral ODS. The most common etiology of unilateral ODS was ON (45.7%), NA-AION (25%), and neuroretinitis (12.5%). Among bilateral ODS, the most common cause was papilledema (30.4%), hypertensive retinopathy (21.7%), diabetic papillitis (13.1%), and optic disc drusen (13.1%). Among unilateral ODS, the mean onset age was significantly older in NA-AION cases than that in ON cases (57.5 years vs. 40.3 years, P = 0.016). Ocular pain was a significant clinical finding observed in ON cases (54.5%) and none in NA-AION cases (P = 0.043). Although there was no significant difference in the initial visual acuity (VA) between NA-AION and ON, the final VA was significantly improved in ON compared to NA-AION (0.31 ± 0.34 vs. 1.14 ± 1.00, P = 0.029). Conclusions Many differential diagnoses must be considered when a patient is presented with ODS. With the increased prevalence of hypertension and diabetes in Malaysia, it is not a surprise that both hypertensive retinopathy and diabetic papillitis together accounted for one-third of the bilateral ODS patients.
Purpose To describe the epidemiology of open globe injuries and its prognostic factors from the perspectives of a tertiary care centre in northern Malaysia. Methods A retrospective study of open globe injuries in a period of three years between June 2017 and May 2020. Patients presenting with open globe injuries were identified and recruited from hospital census. Case records were retrieved and analysed after recruitment. Results A total of 114 patients with 118 open globe injuries were included in the study. Four patients had bilateral eye involvement. Men were found to have seven and a half times higher rate of ocular injuries than women. The predominant age group of ocular trauma presentation was in younger adults between the age of 21 and 30 years old. Work-related injuries account for almost half of the globe injuries (48.7%) followed by motor vehicle accident-related, domestic accident-related, and others. The significant factors related to the visual outcome are presenting visual acuity (VA), presence of relative afferent pupillary defect (RAPD) and vitreous loss. Conclusion The factors related to visual outcomes in this study may aid the clinician in determining the visual prognosis of ocular injuries. Young working males were the most susceptible group to sustain penetrating ocular injuries due to their job nature. Health education and safety at workplace are essential to reduce the occurrence of ocular injuries.
