PURPOSE: To evaluate the mechanism of spontaneous resolution of foveal
detachments and idiopathic macular breaks. METHOD: We reviewed the re
cords of 139 consecutive eyes (94 patients) with either a foveal detac
hment or a macular break in patients who were examined between 1989 an
d 1992, There were 25 men and 68 women (mean age, 66.9 +/- 6.9 years).
They were either unoperated on or observed during the period that pre
ceded surgery. Each patient underwent complete ophthalmic examination
in addition to slit lamp photography of the vitreomacular interface an
d microperimetry with the scanning laser ophthalmoscope. RESULTS: Eigh
t eyes demonstrated spontaneous resolution, A foveal detachment was no
ted in five eyes (five patients) and a stage 2 macular break in three
eyes (three patients). The mean duration of observation was 33 months
(range, one to 144 months). Resolution of the foveal detachments occur
red without the development of posterior vitreous detachment. In each
eye, the presence of a pseudo-operculum, indicating vitreofoveal separ
ation, was accompanied by flattening of the foveal detachment without
detectable posterior vitreous detachment. The three eyes with stage 2
macular break resolved after premature development of a posterior vitr
eous detachment. CONCLUSIONS: Foveal detachment and macular break reso
lution seem to result from the release or weakening of vitreous tracti
on on the fovea. Reattachment of the foveal retina preserves fair to g
ood visual acuity. Surgical intervention is contraindicated (1) in eye
s in which foveal detachment flattens and develops a pseudo-operculum
and (2) when a posterior vitreous detachment develops in an eye with a
stage 2 macular break. Careful biomicroscopic vitreous examination an
d microperimetry with the scanning laser ophthalmoscope are extremely
useful methods for adequate examination of these patients.
