AIM
To describe a new
surgical technique for foveal relocation, and to report the outcome in
nine patients treated with this procedure.
METHODS
Nine
consecutive patients with subfoveal choroidal neovascular membranes
(CNVMs) secondary to age related macular degeneration underwent foveal
relocation surgery by redistribution of the neurosensory retina (RNR).
The technique involved induction of a retinal detachment via a single
retinotomy, relocation of the fovea by "sweeping" the retinal
tissue with a retinal brush, and stabilisation of the retina in its new
location using perfluorocarbon liquid peroperatively and silicone oil postoperatively.
RESULTS
In eight of
nine eyes successful relocation of the fovea was achieved; in one eye
the CNVM remained in a subfoveal location postoperatively. Visual
acuity improved in two eyes, remained unchanged in three, and decreased
in four eyes after a median follow up of 4 months (range 2.5-6
months). Complications included rupture of a foveal cyst with the
development of a macular hole in one eye and epimacular membrane
formation in another eye. In two eyes, macular retinal vessel closure
occurred at the time of laser photocoagulation; one of these eyes later
developed cystoid macular oedema and the other an epiretinal membrane.
Recurrence of the CNVM was observed in one eye, but was controlled with
further laser treatment.
CONCLUSIONS
Foveal
relocation by RNR appears to be feasible, obviating the need for
extensive retinotomies or scleral shortening.
