Purpose:
To examine the safety and efficacy of limited macular translocation followed by laser photocoagulation in the management of subfoveal choroidal neovascularization (CNV) in age-related macular degeneration (AMD).
Methods:
A prospective study was conducted on eight consecutive patients undergoing limited macular translocation followed by laser photocoagulation for the treatment of subfoveal classic CNV form of AMD. Patients were followed up for a minimum of 12 months. The magnitude of foveal translocation, visual outcomes and complications were assessed.
Results:
In all cases the fovea was successfully translocated inferiorly, with a median displacement of 1.1 mm. Thermal laser photocoagulation was subsequently performed in all cases. Visual acuity improved in five eyes, remained unchanged in two eyes and worsened in one eye. The mean improvement in visual acuity was by 0.19 logMAR. At 12 months, six of the eight patients (75%) achieved Snellen visual acuity of at least 6/15, with four patients (50%) achieving Snellen visual acuity of 6/9.
Conclusion:
In this small case series, limited macular translocation was found to be an effective and reproducible means of treating small well-defined subfoveal CNV.
