RESUMO
BACKGROUND: Ophthalmologists/Optometrists have a high incidence of neck pain. Little research has been conducted on specific equipment that predisposes these professionals to cervical discomfort. OBJECTIVE: Primary purpose: to determine if neck position is altered by slit lamp table design. Secondary purpose: to confirm the prevalence of neck pain in eye care professionals. METHODS: A survey of work-related pain was administered to 36 subjects (8 ophthalmologist, 2 optometrists, 26 technicians). The craniovertebral (CV) angle was measured in each subject in three separate positions (resting posture, best posture, slit lamp posture) between two different slit lamps/tables: slit lamp-deep and slit lamp-shallow. RESULTS: 79% of subjects reported neck pain in the last 6 months. The mean CV angle of all subjects at resting posture, best posture, and both slit lamp postures differed significantly. There was also a difference in CV angle between slit lamps. CONCLUSION: Neck pain is more prevalent in eye professionals than in the general population. The use of slit lamps promotes a forward head posture which decreases the CV angle, putting the user at risk for neck pain. By altering slit lamp table design, the CV angle of eye care professionals can be increased, reducing the risk for neck injury.
