Metamorphopsia after successful retinal detachment surgery: an optical coherence tomography study.
OBJECTIVE
To investigate the findings in optical coherence tomography (OCT) in eyes with metamorphopsia after scleral buckling surgery for macula-off retinal detachment.


METHODS
A total of 46 patients (46 eyes) with macula-off retinal detachment were prospectively studied 2 months after successful scleral buckling surgery. Patients were examined with the Amsler grid, fundus biomicroscopy and OCT.


RESULTS
At the 2 month follow-up, 31/46 (67%) patients had metamorphopsia; 24/31 (77%) of these patients had an abnormal macular structure on OCT and 7/31 (23%) showed a normal macula. However, of the 15 patients in the non-metamorphopsia group, 4/15 (27%) had an abnormal macula and 11/15 (73%) had a normal macula (p = 0.0015). The most common finding on OCT was neurosensory retinal detachment.


CONCLUSIONS
Metamorphopsia after scleral buckling surgery in macula-off detachment is more common in patients in whom abnormal macular structure is seen on the OCT scan compared to those showing a normal macular structure. Neurosensory retinal detachment is the most common pathology in these patients.
