Prognostics Factors to Avoid Eye Injuries in Angle Grinders.

Abstract

Objective: To analyze the clinical characteristics and prognostic factors of eye injuries caused by angle grinders over 2 years.

Methods: Clinical data from 36 hospitalized patients (36 eyes) with eye injuries caused by angle grinders were collected. The causes of injury, types of trauma, and prognoses were analyzed.

Results: Among the 36 patients (36 eyes), 34 were male (34 eyes) and 2 were female (2 eyes), with ages ranging from 19 to 66 years. The time from injury to medical consultation was within 12 hours in 29 cases, between 12 and 24 hours in 6 cases, and over 24 hours in 1 case. Primary emergency globe repair surgery was performed within 8 hours of admission in 23 cases, while 29 cases required secondary surgical interventions. Preoperative visual acuity was recorded as no light perception to 0.05 in 13 cases, 0.05 to 0.1 in 10 cases, 0.1 to 0.3 in 9 cases, and >0.3 in 4 cases. Postoperative best-corrected visual acuity was <0.05 in 10 cases, 0.05 to 0.1 in 13 cases, 0.1 to 0.3 in 7 cases, and >0.3 in 6 cases.

Conclusion: Eye injuries caused by angle grinders are often complex, involving both ocular adnexa and globe injuries, with multiple sites of intraocular trauma. A high proportion of patients require secondary surgical interventions. Factors affecting visual outcomes include the location and type of injury, time to medical consultation, presence of infectious endophthalmitis, and intraocular foreign bodies.
