Background: Patients, most of whom are in their 8 th decade of life, can suffer from a minimal acquired esotropia. They complain of blurred vision instead ofdiplopia due to their confusion. This is accompanied with the risk that the investigation covers only monocular disturbances. Patients and Methods: Of 39 such patients, 22 underwent surgery while 10 were fitted with prisms. Another 3 recovered spontaneously and became, therefore, classified as VI th nerve palsies although no limitation of the abduction could be stated. Four patients refused any therapy, and 2 of them recovered in the course of many years. Results: After 2 to 7 years, the individuals corrected with prisms were still compensated while within the operated cohort 3 had a recurrence after years. Conclusions: In almost all cases the prescription of separate glasses for distance with about 3 Delta base out on either side compensates the deviation for several years. In surgical units one finds a summation of chronically decompensated patients with obvious diplopia who need a bimedial recession. Lateral rectus resections are not appropriate as they lead to actual overabduction and final recurrence as well.
