Limited macular translocation (LMT) is one of the treatment options for subfoveal choroidal neovascularisation (CNV) resulting from pathological myopia.1 The fundamental surgical principle involves the transposition of the foveal neurosensory retina to a new site with more healthy underlying retinal pigment epithelium.1,2 Direct laser photocoagulation is usually employed as an adjunct measure in eradicating the original CNV after the surgery. It has been observed that geometrically sizeable translocation is a prerequisite for a long term surgical success.2,3 The degree of translocation is, however, not often predictable and any ineffective displacement may render the subsequent laser photocoagulation extremely difficult or even impossible to perform.2,4 As a result, the recurrent or persistent CNV intruding the newly relocated fovea may jeopardise the final visual outcomes.4,5 Photodynamic therapy (PDT) may be considered a viable adjunct treatment option in such circumstance.
