Epidemiology of Blindness From Facial Trauma: A Multi-Centre Nigerian Study.

Study Design: This is a multi-centre retrospective study. Objective: To determine the prevalence of blindness and pattern of facial trauma associated with blindness among Nigerians. Methods: A multi-centre retrospective study of all patients with facial trauma resulting in blindness, that were co-managed by maxillofacial surgeons and ophthalmologists in 4 Nigerian public tertiary hospitals between January 2010 and December 2019 was undertaken. Data was analysed by IBM SPSS Statistics (version 21.0 for windows, IBM© Inc, Chicago, IL). Results: Of 2070 patients who presented with major facial injuries during the study period, 61 eyes of 56 (2.7%) patients were blind. Blindness was bilateral and unilateral in 5 (8.9%) and 51 (92.1%) patients, respectively. The mean age (SD) at presentation was 36.2 (16.6) years, and 47 (83.9%) of these patients were males. Road traffic accident (n = 27; 48%) was the commonest mechanism of facial trauma, the cheek (n = 18; 40.9%) was the commonest site of associated soft tissue injury and zygomatic complex fracture (n = 19; 24.1%) was the commonest related fracture. Globe rupture (n = 34; 55.7%) was the leading cause of blindness. Enucleation (n = 7; 13.2%) and evisceration (n = 22; 41.5%) were performed on 29 eyes of which 12 (41.4%) patients had ocular prosthesis post-operatively. Conclusions: Blindness was recorded in 2.7% of Nigerians with facial trauma. The commonest mechanism of trauma and cause of blindness in at least one eye were road traffic accident and globe rupture, respectively. Eye removal surgery was necessary in about half of the blind eyes.

Prevention of Earlobe Keloid Recurrence After Excision: Assessment of the Value of Presurgical Injection of Triamcinolone.

The ear is commonly involved in keloid formation, being often pierced. This study estimates the value of pre-excision triamcinolone injection of earlobe keloid, by comparing recurrence rates in patients who only received postexcision triamcinolone injection to those who had it administered before and after excision.The prospective intervention study involved 18 keloid lesions in as many consenting patients who presented with pedunculated earlobe keloid from January 2005 to January 2007.Triamcinolone doses were administered 10 mg/cm of lesion or sutured excision site. Each patient was followed-up for 10 years. Aggregate length of keloid lesions at presentation was 24.4 cm in Group A and 26.5 cm in Group B. Aggregate length of postexcision sutured wound in Group A was 16.1 cm, and 14.8 cm in Group B. Group A patients received a total of 1610 mg of triamcinolone, while a total of 4660 mg of same drug was administered to Group B patients, among whom 3180 mg was delivered presurgically. Total number of clinic visits during the course of treatment in Group A was 10, while that of Group B was 22. No patient with recurrent keloid was recorded in both groups.The authors concluded that there is no advantage to presurgical injection of triamcinolone when excision is considered as part of treatment protocol of a keloid lesion. This study helps to eliminate an ostensibly needless part of a commonly used treatment protocol.

Challenges, attitudes and practices of the spectacle wearers in a resource-limited economy.

PURPOSE: To evaluate challenges, attitudes and practices among spectacle wearers to effect positive change when necessary, and determine positive change in a resource-limited economy. MATERIALS AND METHODS: A multi-hospital descriptive, cross sectional survey of spectacle wearers was conducted between May 2007 and December 2008 in Nigeria. RESULTS: A total of 214 wearers comprising 43.5% males and 56.5% females aged 18-84 years were surveyed. The majority of subjects (92.6%) had at least secondary education. The wearers' challenges included expensive spectacles (43.0%), falling/scratched/broken lenses (29.4%) and fear that spectacles would damage the eyes (23.8%). The wearers' attitudes were comprised of consultations with 'road side dispensers' (7%) and permitting other individuals to select spectacle frames for them (26%). Care and maintaince practices included use of handkerchief, tissue paper, fingers and water to clean spectacles (49.5%) and placing spectacles inside spectacle cases (30.4%). There were no associations (P > 0.05) between gender or literacy levels and who selected the frames for the subjects, caregivers consulted for spectacles, and cleaning materials for spectacles. The placement of spectacles when not in use was significantly associated (P < 0.05) with the wearers' gender and literacy levels but not with the length of spectacle wear. CONCLUSION: Attitudes and practices requiring positive change crossed gender and educational levels among spectacle wearers. The cost of spectacles should be regulated and availability of standard eye care practices would reduce challenges including lens-related defects and quackery. During consultation with a recognized eye care professional, counseling of wearers on positive attitudes/practices as well as allaying fear of spectacle wear is required.
