Introduction: Choroidal neovascularization (CNV) is one of the major causes of blindness and the manifestations are various. These include age-related macular degeneration, myopic subfoveal neovascularization, idiopathic neovascularization, angioid streaks, etc. So far, several treatment methods have been reported. Laser photocoagulation, radiation, transpupillary thermotherapy, and photodynamic therapy are used to treat CNV, including the subfoveal type. Although transpupillary thermotherapy and photodynamic therapy have some effect, we do not find a great increase in visual acuity. Machmer reported macular translocation for age-related macular degeneration using 360 degree peripheral retinotomy (full-retinotomy macular translocation), but the complication rate was very high. Macular translocation by artificial retinal detachment and scleral shortening (limited macular translocation) was reported. After development of new devices and new technologies, the efficacy of full-retinotomy macular translocation is improving. I report here the results of full-retinotomy macular translocation and its complications.
Results: We performed macular translocation on the 42 eyes of 42 patients. The eyes from 32 cases manifest age-related macular degeneration. Eight eyes have myopic CNV, one eye contains angioid streaks, and one eye is idiopathic. New fixation point is located at the new fovea. Mean visual acuity is 0.04 preoperatively, and 0.14 postoperatively. Visual acuity decreased in 4 cases. Retinal detachment occurred in 4 cases. Retinal pigment epithelial detachment occurred in 5 cases. Retinal hemorrhage like BRVO is observed in 4 cases. In these 4 cases, rotation angles were relatively large. In all cases, cyclotropia occurred. Epiretinal membrane occurred in 6 cases. These all complications were treated successfully.
Conclusion: Complication rate is relatively high but macular translocation is very effective for improvement of visual acuity in patients of choroidal neovascularization.
