Abstract

Aims: To review the efficacy of near and distance stereotests in current use and to question the functional benefits of stereopsis based on current evidence.

Method: A literature review was carried out to analyse the current reports of what is a normal level of stereopsis and how and why this varies according to the test used. In addition the role of stereopsis in many aspects of life is evaluated.

Results: The values reported for the normal limits of near stereo-acuity vary greatly with only a weak correlation. Some of the variation can be attributed to test difficulties, such as monocular cues, or the population tested. There is no consensus as to whether near and distance stereo-acuity are equal or vary, and if so which is better. In terms of functional ability stereopsis has been shown to be beneficial in many areas such as academic ability, driving and sports.

Conclusions: The values reported for stereo-acuity continue to pose questions with regard to the best approach for screening and clinical care. With tests now available to assess stereo-acuity in the distance it is anticipated that knowledge of conditions, and subsequent treatment, will improve in conditions such as intermittent distance esotropia. The answer to the question ‘Do we need stereopsis?’ is that it is beneficial but not essential. However, it may be more pertinent to ask ‘What is the precise nature of the benefit?’
