Comparison between ophthalmologists and community health workers in screening of shallow anterior chamber with oblique flashlight test / 中国医学科学杂志(英文版)

ABSTRACT

<p><b>OBJECTIVE</b>To study the agreement between ophthalmologists and community health workers in detecting shallow anterior chamber with oblique flashlight test.</p><p><b>METHODS</b>Totally 425 subjects were given an eye examination in a community health center. The anterior chamber depth of each subject was examined by one ophthalmologist and two trained community health workers (one nurse and one non-professional health worker) using oblique flashlight test. Inter-observer agreement was determined using the weighted kappa statistic.</p><p><b>RESULTS</b>Among the enrolled subjects, 148 (35%) were male and 277 (65%) were female. Good agreement was noted in all the three observers. The comparison between the ophthalmologist and the nurse showed a kappa statistic of 0.42 for both eyes (P < 0.001). The kappa statistic was 0.54 and 0.52 for right and left eyes respectively between the ophthalmologist and the non-professional health worker (P<0.001). As for agreement between the nurse and the non-professional health, worker, the kappa statistic was 0.49 and 0.38 for right and left eyes, respectively (P < 0.001).</p><p><b>CONCLUSION</b>The oblique flashlight test may be used as an applicable tool by trained community health workers for screening of shallow anterior chamber and play a role in blindness prevention in community.</p>
