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 eyeball protrusion 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 this paper, we designed and fabricated a protrusion measuring device using a white light interferometer and measured the protrusion of the human eye and found that the precision and repeatability were significantly higher than the manual measurement method.

The relative position of the eyeballs in the orbit can be a criterion for estimating multiple pathological conditions. Especially, it is useful to diagnose orbital fracture, thyroid eye disease, orbital tumor, and to evaluate the result of drug and surgical treatment. The Hertel and the Naugle exophthalmometer, which are typical measuring instruments used mainly to measure the protrusion of the eye, are inevitably error by the measurer. In this paper, we propose a method to increase the accuracy and repeatability of the measurement of eyeball exophthalmometric values by using a white light interferometer.

The proptosis of 100 healthy Korean young people was estimated. The average protrusion measured with Hertel exophthalmometer was $14.6{\pm}0.51mm$ and $13.7{\pm}0.42mm$ in the right eye, $14.2{\pm}0.46mm$ and $13.6{\pm}0.42mm$ in the left eye by two observers(A, B), and so right eye was higher than left eye. There is no significant difference of proptosis between two eyes and among the visual acuity in the man and woman. The average coefficient of variation among five measurements by two observers was 3.53% and 3.10% in the right eye, 3.32% and 3.11% in the left eye. The mean base line by two observers was $106.7{\pm}1.13mm$ and $108.4{\pm}1.08mm$ in the man, $103.4{\pm}1.23mm$ and $104.8{\pm}1.02mm$ in the woman, respectively.

The purpose of this study was undertaken to determine the analysis of normal values of height of palpebral fissure and Hertel exophthalmometry in Korean woman university students. These measurements were taken from 118 health subjects aged 18-21 years in Korea. In 18-21 years, the mean values of height of palpebral fissure were $6.967{\pm}1.599mm$, $7.172{\pm}1.502mm$, $8.015{\pm}1.44mm$ and $7.1{\pm}1.224mm$, respectively. However, In 18-21 years, the mean values of protrusion were $12.50{\pm}2.33mm$, $12.343{\pm}2.634mm$, $12.773{\pm}1.974mm$ and $13.036{\pm}2.23mm$, respectively. As a results, according to increase the aging, the palpebral fissure height and ocular protrusion was more increase. But in 21 ages the palpebral fissure was some decrease. Also in 19 ages the protrusion was some decrease. On the other hand, the right and left eye have not statistically significant.

The relative position of the eyeballs in the orbit can be a criterion for estimating multiple pathological conditions. Especially, it is useful to diagnose orbital fracture, thyroid eye disease, orbital tumor, and to evaluate the result of drug and surgical treatment. The Hertel and Naugle exophthalmometer, which are the most commonly used measuring instruments for measuring the prominence of the eye, are different from each other. Even if the same examiner repeatedly measures, it is inevitable. Also, even if the same exophthalmometer is different from the manufacturing company, the design of the fixed part of the orbit is different, and a measurement error is caused by the inspectors. In this paper, we propose a method of automatic measurement that can increase the accuracy and repeatability of measurement of exophthalmos using white light scanning interferometer, which is a 3D image measurement technique.

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 $13.59{\pm}1.10mm$. Myopia, distance exophoria, near exophoria, near point convergence, and near point accommodation were measured as $-2.48{\pm}1.91D$, $3.51{\pm}1.78{\Delta}$, $5.73{\pm}2.44{\Delta}$, $9.63{\pm}2.82cm$, and $21.73{\pm}10.28cm$. 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.

Lymphomas of the nasal sinuses are relatively uncommon and represent less than 1% of all head and neck malignancies. Most common symptoms are nasal obstruction, epistaxis, rhinorrhea. We report a case of primary extranodal diffuse large B-cell non-Hodgkin's lymphoma in nasal sinuses accompanying with exophthalmos. A 70-year-old male patient was referred to our hospital with exophthalmos and severe septal deviation. We conducted endoscopic biopsy with septoplasty and biopsy result was diffuse large B-cell lymphoma. He received chemotherapy(R-CHOP) and radiotherapy. At follow-up, he remained free of disease.

Granulocytic sarcoma is a manifestation of myelogenous leukemia, which means a solid mass consisting of primitive precursors of the granulocytic series of white blood cells. We present CT and MR imaging findings of bilateral sino-orbital granulocytic sarcoma in a 22-month-old boy. The mass involved bilateral orbital fossa which resulted in bilateral proptosis. Moreover, the mass extended to the almost skull base including paranasal sinuses, maxilla, temporal bone, zygomatic bone, sphenoid bone, ethmoid, and palatine bone. The adjacent dura was continuously thickened and the lower half of cavernous sinus was also involved. The patient was diagnosed as AML (M5) with t(8,21) translocation through a chromosome study from the bone marrow.
