- Alternative Abstract
- The relative position of the orbital eye can be a criterion for evaluating several pathological conditions. It is especially useful to diagnose orbital fractures, thyroid eye disease, orbital tumors and to evaluate the outcome of medication and surgical treatment. Hertel and Naugle are representative measurement tools used to measure exophthalmometic values, and have different measurement results, such as fixed orbits, every time they are inspected, even if the same inspector repeatedly measures them. Even with the same calibrator, it is inevitable that different manufacturers will change the design of the stationary part of the orbit, causing the surveyor to make a measurement error. In order to improve the error of the conventional manual protrusion system, we designed and manufactured an automatic protrusion measuring system using a white light interferometer, which has already been used in the inspection and measurement fields of the semiconductor and display industries. And to show better measurement reproducibility. The degree of protrusion of the eyeball was measured 50 times using a system proposed by one subject in 44 eyes of 22 subjects. The error of measurement of the orbital projection using the proposed system is ±0.041㎜, which is more reproducible than the error of ±1.0-1.5㎜ of the conventional manual orbital system. Diagnosis of orbital fracture, thyroid eye disease, orbital tumor, And to evaluate the outcome of surgical treatment.
