Insights
Superior oblique paresis (SOP) in young children is not linked to new intracranial issues. While surgery can improve motor alignment, sensory outcomes often remain unchanged, especially in younger patients.
Area of Science:
- Ophthalmology
- Pediatric Neurology
- Neuroscience
Background:
- Superior oblique paresis (SOP) is a common cause of strabismus in children.
- Early diagnosis and management are crucial for optimal visual development.
- Understanding the long-term outcomes of SOP is essential for clinical practice.
Purpose of the Study:
- To evaluate the sensory and motor results of superior oblique paresis (SOP) in patients under 8 years old.
- To determine if SOP presentation is associated with underlying intracranial pathology.
Main Methods:
- Retrospective observational case series.
- Analysis of 92 patients under 8 years old with SOP treated at an outpatient university center.
- Evaluation of sensory and motor outcomes, including surgical and non-surgical management.
Main Results:
- Congenital causes were most frequent (56 patients).
- Motor alignment improved with surgery (87% within 5 prism diopters), but sensory outcomes did not significantly improve.
- Patients presenting before age 4 had worse sensory outcomes.
Conclusions:
- SOP in young children is not associated with the development of new intracranial pathology.
- Surgical intervention for SOP generally leads to satisfactory motor outcomes but often does not improve sensory function.
- Younger age at presentation (<4 years) is linked to poorer sensory outcomes.
Purpose:
To examine sensory and motor outcomes of superior oblique paresis (SOP) presenting in patients < 8 years old and to ascertain whether SOP was ever the presenting manifestation of intracranial pathology.
Methods:
Retrospective observational case series of SOP in children < 8 years old in an outpatient university center.
Results:
Ninety-two patients with SOP presented at a median age of 3.9 years. The etiologies were likely congenital (n = 56), craniofacial anomalies (n = 12), head trauma (n = 5), postresection of brain tumors (n = 3), orbital inflammation (n = 1), prenatal stroke (n = 1), and unknown (n = 14). Twenty-six were followed-up for a median of 2.1 years and did not have surgery; 46 were followed-up for a median of 3 years and did undergo surgery. No cases of new intracranial pathology occurred during follow-up. In 42 patients observed for at least 6 months without surgery, motor status was stable or improved (each in approximately one third of cases) or deteriorated (in one fourth of cases). Motor outcomes were better (P =.01) in patients undergoing surgery (87% aligned within 5 prism diopters) than in those not undergoing surgery despite worse presenting deviations. Sensory status did not show a similar improvement with surgery. Patients presenting before age 4 had worse sensory outcomes (P =.00001) than patients presenting later. At the last examination, 4 patients had vision < 20/40 from amblyopia.
Conclusions:
SOP in children < 8 years old was not associated with the development of new intracranial pathology. Motor alignment and sensory function were often stable, although some patients improved, and others deteriorated. With surgery, satisfactory motor outcomes were usually achieved, but sensory status often was not improved. Sensory outcomes were generally worse in patients presenting at younger ages.
