TitleSpecific forms of slow progressive strabismus
PurposeStrabismus population has changed in the past decades with an increasing number of adult strabismus cases. The purpose of this report is to give an overview of slow progressive forms of strabismus that can be successfully treated either by non-surgical means or by strabismus surgery
MethodsSlow progressive strabismus is often related to neurogenic etiologies but mechanical causes have to be considered. Recent advances in the knowledge of the anatomy and physiology of extraocular muscles and their associated connective tissue have stressed the importance of orbital imaging in the study of adult strabismus.
ResultsAcquired strabismus of mechanical origin can be due to connective tissue degeneration, inflammatory diseases as thyroid eye disease and idiopathic orbital inflammatory disease, infectious pathology with slow progressive necrosis of the orbital wall , orbital tumors and iatrogenic causes. Connective tissue degeneration leading to relative dislocation of ocular muscles can be associated with high myopia, but also nonmyopic patients may develop similar strabismus patterns: age-related distance esotropia and simulated Brown patterns may be due to pulley pathology.
Diagnosis and treatment of these specific forms of slow progressive strabismus will be discussed.
ConclusionPhysiologic as well as pathological alterations of orbital structures may account for a large spectrum of strabismological symptoms. Every clinican should be aware of these pathogenic mechanisms, which have often a favourable prognosis
