Background:
Cicatricial conjunctival constriction rings caused by trauma seriously influences visual function and causes blepharon deformities. The treatment of cicatricial conjunctival constriction rings is intractable.
Methods:
A 45-year-old male presented severe cicatricial conjunctival constriction ring due to traffic accident injury. This 5-mm diameter constriction ring resulted in the patient's eyelid deformities, including eyelid ptosis, ectropion, and visual obstruction. The patient underwent primary surgery of serial conjunctival Z-plasty for correction of the constriction ring. Conjunctival constriction ring was corrected immediately after Z-plasy. Fornix deepening suturing was adopted to promote formation of fornix and correct eyelid ectropion. A secondary surgery of frontalis flap suspension was adopted to correct ptosis 6 months after Z-plasty.
Results:
The patient achieved a satisfactory and symmetrical appearance with no recurrence of cicatricial conjunctival constriction and no other complications during the 6-month follow-up period.
Conclusion:
In this patient, the authors claimed that serial Z-plasty surgery can effectively be used for correction of cicatricial conjunctival constriction rings. No further material implantation was applied during the operation.

In this pathway, the target proteins are first tagged with small proteins called ubiquitin. A series of enzymes carry out the ubiquitination of the target proteins - E1 (ubiquitin-activating enzyme), E2 (ubiquitin-conjugating enzyme), and E3...
