Summary
Twenty-four percent of patients with double vision (diplopia) showed cyclodeviation, often caused by superior oblique palsy. Most cases of vascular-origin cyclodeviation improved spontaneously.
Area of Science:
- Ophthalmology
- Neuro-ophthalmology
Background:
- Diplopia is a common visual complaint.
- Cyclodeviation, a form of torsional misalignment, can contribute to diplopia.
- Understanding the incidence and causes of cyclodeviation is crucial for diagnosis and management.
Purpose of the Study:
- To determine the incidence of cyclodeviation in patients presenting with diplopia.
- To analyze the underlying diseases causing cyclodeviation.
- To describe the clinical manifestations of cyclodeviation.
Main Methods:
- Retrospective review of 266 patients aged 15+ with diplopia.
- Lancaster red-green test (LRGT) used to detect cyclodeviation.
- Comparison of LRGT findings with Maddox double-rod test and fundus photography.
Main Results:
- Cyclodeviation was present in 24% (63/266) of patients.
- Superior oblique palsy was the most frequent cause (42 patients).
- Excyclodeviation (57 patients) was more common than incyclodeviation (4 patients).
Conclusions:
- A significant proportion of diplopia patients exhibit cyclodeviation, even without torsional diplopia complaints.
- Superior oblique palsy is the leading cause of cyclodeviation.
- Vascular-related cyclodeviation shows a high rate of spontaneous recovery.
