Conjunctival Autografts for Ocular Surface Reconstruction after Conjunctival Nevus Excision.

PURPOSE: The aim of this study was to evaluate the clinical and therapeutic outcomes of the cases where we used conjunctival autografts with and without the Tenon fascia for ocular surface reconstruction after conjunctival nevus excision.

METHODS

This study included 63 eyes of 63 patients who underwent conjunctival nevus excision between January 2013 and December 2020. Although a Tenon-free conjunctival autograft was used in 32 eyes of 32 patients in group 1, a Tenon-containing conjunctival autograft was used in 31 eyes of 31 patients in group 2. The clinical and histopathological characteristics of the nevus, complete graft epithelization, cosmetic outcomes, and postoperative complications were evaluated.

RESULTS

Conjunctival autografts were harvested from the contralateral eye in 3 eyes (9.3%) in group 1 and 2 eyes (6.4%) in group 2 ( P = 0.66). Postoperatively, the mean defect size at the harvest site was 5.3 ± 1.4 mm in group 1 and 5.5 ± 1.5 mm in group 2 ( P = 0.47). Graft edema was observed in only 1 case (3.1%) in group 1 and 6 cases (19.3%) in group 2 ( P = 0.04). Although a complete graft epithelization was observed in all eyes in group 1, fluorescein staining was present in 2 eyes (6.4%) in group 2 ( P = 0.14). Cosmetically, retracting and shrinking grafts were absent in group 1, whereas group 2 had in 4 eyes (12.9%) ( P = 0.03). Neither group had conjunctival scarring, symblepharon, eyelid cicatrization, dysmotility, or pannus at the donor site.

CONCLUSIONS

Ocular surface reconstruction with a Tenon-free conjunctival autograft after conjunctival nevus excision provides excellent cosmetic and functional results without significant complications.
