|
Purpose: This study was to find the correlation between exophthalmetry and visual functions.
Methods: Exophthalmetry and visual functions of 200 adults without ophthalmophathy and general disease were examined. Exophthalmetry were measured with Hertel's exophthalmometer. Visual functions (myopia, distance exophoria, near exophoria, near point of convergence, near point of accommodation) were measured for three times.
Results: The exophthalmetry was 13.59±1.10 mm. Myopia, distance exophoria, near exophoria, near point convergence, and near point accommodation were measured as ?2.48±1.91 D, 3.51±1.78 ?, 5.73±2.44 ?, 9.63±2.82 cm, and 21.73±10.28 cm. With increasing exophthalmetry, the unaided visual acuity, myopia and astigmatism were decreased. On the other hand, distance exophoria, distance esophoria, near exophoria, near point of convergence and near point of accommodation were significantly increased, while exophthalmetry was increased.
Conclusions: The relationship between visual functions and exophthalmetry were found to be statistically significant. It could be used as the clinical criteria for prescription of binocular inspections.
