The pre-myopic syndrome.
Considering the social importance of myopia in industrialised countries, this study aimed to research criteria which could determine whether a person might become myopic. For this purpose, a sample of 25 emmetropic (plano to +0.75 D) subjects, who became myopic during the 2 years following the initial eye examination (the pre-myopic group), were compared to a matched sample of subjects who did not become myopic during the same period. The results show at the 95% statistical level of confidence, that the pre-myopes have particular characteristics, such as a loss of physiological hyperopia, a more positive near retinoscopy and near cross-cylinders and tendency to esophoria. The test of dioptric variations* points to a decrease in the dynamics of accommodation as well as non-overlapping of near and far comfort zones.
