DISADVATAGES OF ”LMT”1-Choroidal hge:-Radial scleral outfolding has the disadvantage of being moreunfamiliar to surgeons and carries risk of subretinal and choroidalhemorrhage during suture placement, the choroid may unintentionallyperforated during suturing of the full-thickness fold(Jeffrey, 2001).2-Less effective than MT360 in stabilizing or improving visualacuity:-Looking only at the patients in these two groups who hadstandardized visual acuity (median 10 months postop; range 6 to12 months), there was less than three lines of vision lost after LMTwith scleral infolding group, and less than one line median visualacuity loss in the ”MT360” retinotomy group.Overall, 24% of patients with LMT ”scleral infolding”achieved a visual acuity of (20/100) or better, compared to 35% inthe MT360° retinotomy group ( Kronemyer, 2001).3- Un predicted foveal displacement due to different factors:-Elasticity of viable retina, extent, and location of intraoperativeretinal detachment , postoperative positioning , retinal folds , andReview of literatures- 81 -other undetermined factors may also contribute to fovealdisplacement in patients undergoing limited macular translocation( Sullivan et al, 2002).Possible complications of vitrectomy surgery and othercomplications of macular translocation such as choroidalhaemorrhage are understood in advance by the patient and surgeon.Further improvements in surgical technique may improve thepredictability of foveal displacement and increase the utility oflimited macular translocation in patients with subfoveal CNV fromAMD or other associated conditions ( Sullivan et al, 2002).
