Paget's disease can cause optic neuropathy, leading to visual field defects like scotomas. The exact cause remains unclear, as bony compression is not always present, and treatment showed no improvement.

Area of Science:

Ophthalmology
Neurology
Endocrinology

Background:

Paget's disease of bone is a chronic condition affecting bone remodeling.
Optic neuropathy is a potential complication, impacting vision.
The underlying mechanisms of optic neuropathy in Paget's disease are not fully understood.

Purpose of the Study:

To investigate the prevalence and characteristics of visual field defects in patients with Paget's disease.
To explore the relationship between radiographic findings and optic neuropathy.
To assess the efficacy of synthetic salmon calcitonin in treating optic neuropathy associated with Paget's disease.

Main Methods:

Retrospective analysis of 22 patients with Paget's disease.
Ophthalmological examination including visual field testing.

Radiographic assessment for evidence of optic canal involvement.

Main Results:

Nine out of 22 patients (41%) exhibited visual field defects, primarily arcuate scotomas.
Only two patients had radiographic evidence of optic canal constriction.
No objective improvement in optic neuropathy was observed in three patients treated with synthetic salmon calcitonin.

Conclusions:

Optic neuropathy in Paget's disease may not solely result from bony compression.
The etiology of optic neuropathy in patients with normal optic canals remains unknown.
Further research is needed to elucidate the pathogenesis and identify effective treatments for this condition.
