Morphological examination of the intraorbital muscles (musculi bulbi) in Persian cats in the perinatal period.

The study involved 34 fetuses of Persian cats from eight uteruses, gestational day 58. The intraorbital muscles were analysed morphologically in respect of the location of the recti muscles, oblique muscles and retractor bulbi muscle, their length and breadth, the distance of the muscle tendon insertions from the corneal limbus and the line of insertions.
