[Pathological observation of the anterior eye segment following isolation of the vessels in the rectus by microdissection].
OBJECTIVE
To investigate the impact of simultaneously isolating the vessels in 4 recti of one eye by means of microdissection on the anterior segment.


METHODS
Among the 16 dogs, 8 received coupling of the recti (with Jensen procedure) and the others received rectus displacement (with Hummelsheim procedure). Microdissection of the anterior ciliary arteries (ACAs) were performed and 3 months later, the anterior segment tissues were observed with both light and electron microscopes.


RESULTS
Most of the ACAs were successfully isolated and preserved which were thicker in the vertical recti than in the horizontal recti. No signs of anterior segment ischemia (ASI) were observed in the 16 eyes with the operation postoperatively.


CONCLUSIONS
Vascular microdissection in strabismus surgery that involves 3 or 4 recti might avoid the risk of ASI, during which the ACAs of the vertical rectus should be carefully preserved.
