The contralateral upper eyelid in ptosis: some observations pertinent to ptosis corrective surgery.
The validity of Hering's law in corrective surgery for ptosis is demonstrated for the first time. It is also shown how Hering's law has been utilised in corrective surgery for unilateral ptosis to elicit a predominant response from the unoperated contralateral upper eyelid. Other implications of reciprocal innervation of the 2 upper eyelids are discussed and a tentative hypothesis is postulated...
متن کاملEvaluation and management of unilateral ptosis and avoiding contralateral ptosis.
Treating unilateral ptosis can be challenging and a proper preoperative evaluation may help prevent unexpected outcomes on the contralateral lid. Preoperative evaluation should include testing for Hering's law, which remains useful in understanding the phenomenon of induced contralateral eyelid retraction in the context of ptosis. Approximately 10% to 20% of patients with unilateral ptosis have...

متن کاملAdjustable sutures in eyelid surgery for ptosis and lid retraction.
New techniques are described and illustrated for ptosis and lid retraction surgery in which the sutures holding the upper eyelid position are adjustable postoperatively. In the anterior approach, the sutures pass from the levator muscle through the anterior surface of the tarsal plate at the position of the skin crease and are tied at the skin crease incision. In the posterior approach, the sut...

Examination.-The visual acuity was 6/9 in each eye. Refraction under atropine revealed slight hypermetropia. Both fundi were normal. The movements of the eyes were full and the eyes were orthophoric on cover test. The action of the left superior rectus was normal. The child was attempting to correct the lid deformity by elevating the eyebrow. There was no evidence of jawwinking (Marcus Gunn phe...
