What Is the Recovery Factor of the Visual Acuity for the Intraorbital Tumor?

The intraorbital tumor may cause an exophthalmos only. But sometimes it cause the acute visual disturbance. In this paper, we focus on the visual acuity and preoperative condition.

Material and Method: We reviewed surgical cases of primary orbital tumors and selected the cases which had visual disturbance pre-operatively. We studied the tumor size, pathology, tumor location, and pre-/post-operative visual acuity in 87 patients.

Results: The tumor size, pathology and tumor location were not significantly related to the post-operative visual recovery. All patients who had the visual acuity better than the 30cm finger counting (30 cm/f.c.) recovered the visual acuity post-operatively. But only one in eight patients who had the visual acuity worse than 30 cm/f.c. recovered. Preoperative visual acuity wad deeply related the post-operative recovery of the visual acuity.

Conclusions: In the intra-orbital tumor cases, if the visual disturbance was occurred, surgical approach was deeply recommended the patient with the visual acuity better than 30 cm/f.c..
