Macular Translocation
Ehab Mohammed Abo Ali;
Abstract
Macular translocation is defined as any surgery that has a primary goal of relocating the central neurosensory retina or fovea to an area outside the border of the underling lesion intraoperatively or postoperatively.
Macular translocation was developed to overcome the disappointing results of other treatments of the choroidal neovascular membrane including laser photocoagulation, photodynamic therapy and surgical removal of it.
The rationale of macular translocation is to move the neurosensory retina in an eye with recent-onset subfoveal lesion to a new location with presumably healthier RPE and choriocapillaris away from the lesion. Mechanisms allowing foveal displacement are:
1. Disinsertion of retina from its anterior attachment (large retinotomty
technique).
2. Chorioscleral shortening leading to redundancy of retina relative to
the underlying eye wall.
3. Stretching of the retina during subretinal injection of B.S.S. leading to redundancy of the retina (Au-Bong et al., 2001).
Currently, the most common subfoveal lesion treated with macular translocation is CNV related to the following diseases:
1. Age related macular degeneration (the most common indication).
2. Ocular histopalsmosis syndrome.
3. Pathologic myopia.
- 4. Angioid streaks (Thomas et al., 1999).
