[Pathomorphological evaluation of the extraocular muscles during strabismus]
1Oddziału Klinicznego Okulistyki Instytutu Centrum Zdrowia Matki Polki w Lodzi.
Purpose:
An analysis of the histopathological picture of extraocular muscles removed in the operation of strabismus.
Material And Methods:
Light microscopy analysis included 131 fragments of rectus muscles, with the majority of lateral, collected from patients with concomitant squint of different angles and disease durations.
Results:
Normotopic cross-striated muscle fibres were observed in 40 (30.6%) studied muscles, while pathological changes appeared in 91 (69.4%) muscles with a prevailance of fibrous atrophy. A correlation was found between the histopathological picture of the examined muscles and the extent of strabismus.
Conclusions:
Pathomorphological changes were observed with the majority of the extraocular muscles in the microscopic picture. The observed changes in the cellular structure of the extraocular muscles influenced the extent of the squint angle, affecting the result of surgery.
