The measurement of ocular alignment can be challenging and difficult to reproduce. A method for the measurement of ocular alignment with accuracy, speed, and reproducibility would be a useful clinical addition. Materials and methods: A hand-held device consisting of a rotary prism and a red Maddox rod was constructed. This was used to evaluate 18 patients with ocular misalignment and the results were compared with the ones obtained using the prism cover testing. Results: The results from the hand-held device showed a close correlation with those of the prism cover test. Conclusion: The hand-held instrument is a useful method to quantify ocular misalignment and correlates with the prism cover test results.
