Objectives: To determine the effects of interventions for eye movement disorders on functional ability following stroke.
Search methods: We searched the Cochrane Stroke Group Trials Register (February 2011), the Cochrane Eyes and Vision Group Trials Register (December 2009) and nine electronic bibliographic databases including CENTRAL (The Cochrane Library 2009, Issue 4), MEDLINE (1950 to December 2009), EMBASE (1980 to December 2009), CINAHL (1982 to December 2009), AMED (1985 to December 2009), and PsycINFO (1967 to December 2009). We also searched reference lists and trials registers, handsearched journals and conference proceedings, and contacted experts.
Selection criteria: Randomised trials in adults after stroke where the intervention was specifically targeted at improving the eye movement disorder or improving the ability of the participant to cope with the eye movement disorder. The primary outcome was functional ability in activities of daily living. Secondary outcomes included functional ability in extended activities of daily living, eye movement measures, balance, falls, depression or anxiety, discharge destination or residence after stroke, quality of life and social isolation, adverse events, and death.
Data collection and analysis:
Two authors independently screened abstracts, extracted data and appraised trials. We undertook assessment of methodological quality for allocation concealment, blinding of outcome assessor, method of dealing with missing data, and other potential sources of bias.
Main results: Two studies (28 participants but only five were people with stroke) met the inclusion criteria and were included in this review. Both studies investigated pharmacological interventions for disorders of eye movement in patients with stroke. It was not appropriate to pool data and we were not able to draw conclusions from these studies. We found no other randomised studies which investigated interventions for disorders of eye movement in patients with stroke.
Authors' conclusions: There is insufficient evidence to reach conclusions about the effectiveness of interventions for patients with eye movement disorders after stroke. High quality research in the form of well-designed randomised trials are urgently required.
