Summary
Computed tomography (CT) scans can assess eyeball atrophy severity. Adjusting CT window settings improves measurement stability and accuracy for diagnosing ocular conditions.
Area of Science:
- Ophthalmology
- Radiology
- Medical Imaging
Background:
- Traumatic atrophied eyeballs often present with intraocular structural disorders and corneoscleral thickening.
- Conventional diagnostic methods lack accuracy and objectivity in determining eyeball atrophy severity.
Purpose of the Study:
- To evaluate the efficacy of computed tomography (CT) in measuring axial length and eyeball volume for assessing ocular atrophy.
- To determine if adjusting CT window width and position enhances measurement stability and accuracy.
Main Methods:
- A before-and-after control study involving 48 atrophied eyes and 48 healthy eyes.
- Three CT examinations were performed on each eye using conventional and adjusted window settings.
- Statistical analysis using the discrete coefficient of variation assessed measurement stability.
Main Results:
- Adjusted CT window settings more accurately depicted ocular contours.
- The adjusted group showed significantly greater measurement stability compared to the conventional group (P<0.05).
- The CT measurement method effectively determined the severity of eyeball atrophy.
Conclusions:
- Computed tomography (CT) is a viable tool for diagnosing ocular atrophy and its severity.
- Adjusting CT window width and position significantly enhances measurement stability and diagnostic accuracy.
