| dc.description.abstract | OBJECTIVE: To present clinical feature of Heimann-Bielschowsky phenomenon and strabismus association. DESIGN: Retrospective case series. MATERIAL AND METHOD: Medical records of cases between January 2004 and January 2008 were reviewed. Eight cases met the criteria. Age, sex, visual acuity, and eye examination data were collected. RESULTS: Six cases were male and two cases were female. Age at presentation ranged from 4 to 45 years old. Seven cases had vision of 6/60 or worse. Only one case had visual acuity 6/36. Strabismus was seen in five cases (exotropia 4 cases and esotropia 1 case). No one had symptoms of diplopia or oscillopsia. All cases had unilateral coarse, slow, pendular vertical oscillations occurring in the poor vision eye. CONCLUSION: Monocular vertical oscillation may develop in an eye with reduced vision. It may be a common condition but under diagnosed. | en_US |
