Observation of idiopathic full-thickness macular holes. Follow-up observation.

OBJECTIVES
To evaluate the long-term follow-up observation of idiopathic full-thickness macular holes, with emphasis on the incidence and process of disappearance.


METHODS
The authors followed up 97 eyes with idiopathic full-thickness macular holes for a period ranging from 2 to 182 months (average, 66 months).


RESULTS
Apparent disappearance of the hole was observed in six eyes. Although improvement in visual acuity of at least 2 lines resulted in all six eyes, visual acuity improved to 20/30 or better in those eyes in which macular holes disappeared within 24 months of the initial examination.


CONCLUSION
The incidence of apparent disappearance of idiopathic full-thickness macular holes was low. Improvement in visual acuity was greater in those cases in which macular holes disappeared in a relatively short period of time.
