Fig. 17. Illustrations demonstrating the mechanism of RD in eyes with coloboma.
A Peripheral break present, ICM breaks absent and no dehiscence at Locus minoris resistantiae: only peripheral break contributes to the RD and RD does not extend into coloboma. B Peripheral break present, dehiscence at Locus minoris resistantiae present, ICM break absent: only peripheral break contributes to RD but RD extends into the coloboma. C ICM break present, dehiscence at Locus Minoris resistantiae present, peripheral retinal break absent: fluid spreads through ICM break to cause ICM detachment before spreading beyond coloboma to cause RD. D ICM break present, dehiscence at Locus minoris resistantiae present, peripheral retinal break present: fluid enters sub-retinal space both from peripheral retinal break and through break in ICM.
