Under this title many cases have since been reported. In this country Parker and Fralick2 in 1931 reported what appears to have been a case of true choroideremia. They made the interesting speculation that choroideremia is analogous to coloboma of the macula, assuming that the former condition results when the extramacular, and the latter when the macular, system of choroidal vessels fails to develop. Since, however, choroideremia has never been observed microscopically, it is not certain that the anomaly has ever actually occurred. And even in cases such as that described by Parker and Fralick,
