Objective

Lea test and E Snellen test were compared prospectively to measure their reliability for visual acuity screening and early detection of amblyopia.

Methods

Thirty children aged less than 6 years with pseudophakic eyes and thirty other visually healthy were assessed for visual acuity. Each child was screened twice with both tets.

Results

Children aged less than 2 years couldn't be sceened by line test, so we used functionnal tests. E Snellen test was easily recognised and named than Lea test by children aged more than 2 years. Some symbols wre identified, named and pointed with difficulties by children of both groups (the apple symbol and house symbol). Lea test was difficult to use with mental retardation and hearing and speech troubles conditions.

Conclusions

Lea test symbols are very sensitive for detection of amblyopia in cooperative children. In Africa as most of children are literate and these symbols are not familiar to our social reality, it is compulsory to train children and their parents in the clinic or at home before starting with visual acuity assessment.
