ABSTRACT
AIM: The aim of the study was to report the etiology, pattern, and spectrum of ocular injuries in patients with maxillofacial injuries seen at a tertiary care hospital in northern Nigeria. PATIENTS AND METHODS: This is a retrospective evaluation of the etiology, spectrum, and treatment of ocular injures seen in patients with midfacial fractures, who presented at Ahmadu Bello University Teaching Hospital, Shika-Zaria, Nigeria, a tertiary care hospital in northern Nigeria. Cases were seen at the oral and maxillofacial clinic for those presenting with midfacial fractures, whereas those presenting with ocular injuries due to midfacial injuries were referred from the ophthalmology department. Data were collected on their demographics, etiology of injuries, body part(s) involved, and treatment. RESULTS: A total of 256 patients had midfacial injuries during the period, of which 219 patients had 357 associated ocular injuries. The age range was between 3 and 76 years. There were more males (83.8%) than females (16.2%), giving a male-to-female ratio of 5.2:1; the 21-30 years' age bracket was most frequently affected (38.4%). The predominant etiology of injuries was road traffic accidents (RTAs) (90.1%), followed by assault (4.9%). Zygomatic complex fractures (38.6%) and orbital wall fractures (24.7%) were the common midfacial injuries. There were 357 ocular injuries, giving a patient: injury ratio of 1:1.6, with subconjunctival hemorrhage (32.5%) and ruptured globe (20.0%) being common. Treatments performed were reduction and immobilization of midfacial fractures plus evisceration (32.0%), followed by reduction and immobilization of fractures alone (23.9%) and reduction and immobilization plus grafting of soft tissues (21.2%). CONCLUSION: Ocular injuries are quite common in patients with midfacial injuries, with a ratio of 1.6:1. RTA was the most common etiology, with zygomatic complex fractures as the most common midfacial injury. Subconjunctival hemorrhage was the most common ocular injury manifestation, with young adults (21-30 years of age) being most affected. Treatment often involved reduction and immobilization of midface fractures with evisceration and grafting of ocular tissues.
ABSTRACT
Background: Smartphone applications (apps) are increasingly becoming more popular for medical use. Aim: The aim of this article is to determine the willingness and ease of using smartphone apps for visual assessment among adult patients attending the general outpatient ophthalmology clinic of Ahmadu Bello University Teaching Hospital, Zaria in Nigeria. Design: The study was a hospital-based descriptive cross-sectional design. Materials and Methods: New and old adult patients who presented at the clinic and consented to the study were selected. Visual acuity assessment was done using a 6-m Snellen chart and three selected Smartphone visual acuity applications sequentially. A semi-structured questionnaire was used for data collection and then analysed using SPSS version 23. Results: A total of 287 patients were studied. Majority (96%) of the patients found the Smartphone apps to be easy to use. A good proportion (76%) of the patients also believed that Smartphone charts were easier to use than the conventional Snellen chart and expressed willingness to use the app again. Conclusion: Smartphone visual acuity apps could offer a convenient, easy-to-learn, and easy-to-use means of visual acuity assessment. This coupled with the demonstrated patient's willingness to embrace this technology could be used to encourage the use of clinically validated apps for the early detection as well as monitoring of any impairment of vision, especially in out-of-clinic situations.
ABSTRACT
BACKGROUND/OBJECTIVE: Deaf persons are equally susceptible to other otologic diseases as the rest of the population; however, there may be increased morbidity among the deaf population. The aim of the study is to determine common otologic problems and their prevalence among the deaf and to offer treatment where appropriate. MATERIALS AND METHODS: Six hundred and twenty students aged between 5 and 38 years with profound hearing loss were recruited from a special school for the deaf. Hearing level was assessed and full ENT examination including otoscopy was done. RESULTS: 22.4% [139] of the deaf students had otologic diseases, with 69.1% of them having wax impaction and chronic suppurative otitis media and otitis media with effusion accounting for 21.6 and 7.2% respectively. CONCLUSION: The study showed that wax impaction is a common problem and this can be quite uncomfortable for some of the students. A routine general and otologic screening program targeted at the deaf and deaf-blind is recommended.
