Background: Macular rotation to treat exudative age-related macular degener
ation (AMD) involves translocation of the fovea to a site with intact retin
al pigment epithelium. To avoid the inevitable postoperative cyclotropia we
combined this procedure with torsional muscle surgery. Patients and method
s: In 30 eyes the macula was rotated upward by 30-50 degrees following comp
lete artificial retinal detachment and a 360 degrees retinotomy. Simultaneo
us torsional muscle surgery was not carried out in the first 8 eyes; in the
remaining 22 eyes surgery of the oblique muscles was performed alone or in
combination with surgery of two or four rectus muscles. Simultaneously or
later, muscle surgery was performed on the fellow eye in 17 of these patien
ts. Three of the eight patients who had no primary muscle surgery were oper
ated on later. They had muscle surgery on the macular-rotated eye and on th
e fellow eye. Results: Postoperatively, the silicone oil was removed from a
ll but one eye and an intraocular lens implanted in all but two eyes. Five
eyes developed a postoperative retinal detachment, three of them with proli
ferative vitreoretinopathy. Three other eyes developed a recurrence of the
choroidal neovascularization. At last examination, 18 of the 30 eyes (60%)
had a near vision of 0.4 or better, sufficient for the reading of normal ne
wsprint. Six of the eight patients who did not undergo muscle surgery repor
ted considerable disorientation caused by the postoperative diplopia and cy
clotropia. The muscle operation, which has been performed in a total of 25
patients, conferred complete freedom from complaints in all but one patient
. Conclusion: Macular rotation succeeded in restoring reading vision in abo
ut half of cases of exudative AMD, at least in the short term. The most ser
ious complication was the development of a retinal detachment. The extremel
y disorienting side effects of diplopia and tilted image could be prevented
or effectively treated by muscle surgery for counter-rotation of the globe
, if need be also in the fellow eye.
