[Clinical Characteristics of Rhegmatogenous Retinal Detachment in Highly Myopic and Phakic Eyes].
OBJECTIVE
To evaluate clinical characteristics of rhegmatogenous retinal detachment in high myopic and phakic eyes.


METHODS
The subjects were 1174 eyes of phakic rhegmatogenous retinal detachment detected in 1199 eyes that underwent initial vitreoretinal surgery between April 2006 and March 2011. Eyes with macular hole retinal detachment or secondary retinal detachment were excluded. The 486 eyes with high myopia (spherical equivalent ≤ -6.0 D or axial length ≥ 26.5 mm) and the 688 eyes with non-high myopia were compared.


RESULTS
The mean age was significantly younger in the high myopia group (42.7 ± 14.2 years old, p < 0.001) with a single peak of higher incidence in 40 years old. The retinal detachment caused by retinal hole was significantly frequent in the high myopia group (p < 0.001) and that caused by retinal tear was less frequent (p = 0.021). The initial retinal attachment rate and the final attachment rate were not significant. In the fellow eye of the high myopia group, the incidence of retinal detachment and lattice degeneration were more frequent (16.7%, 20.4%, respectively).


CONCLUSIONS
The incidences of the retinal detachment in younger age and those caused by retinal holes were higher in the high myopia group. Higher incidence of retinal detachment and lattice degeneration in the fellow eyes of the high myopia group indicated that careful observation also in the fellow eyes was recommended.
