Résultats préliminaires de la technique d'excision du ptérygion avec autogreffe conjonctivale

Abstract

14 eyes with a pterygium, including one eye from which a pterygium had previously been removed by a simple excision, underwent a conjunctival autograft. During an average follow-up of 13 months, we observed a recurrence in 5 eyes (35%). The visual acuity stayed unchanged in 10 eyes, worsened in 1 eye and improved in 3 eyes. The corneal astigmatism measured with a Javal keratometer showed a modification in 12 eyes. This method should not be used as a standard primary surgery for pterygium in view of the high recurrence rate observed.

Comparison of Conjunctival Autograft With Amniotic Membrane Transplantation for Pterygium Surgery

“…7,8 With conjunctival autograft transplantation (CAT), these rates drop to 2%-35%. 9 Using antimetabolites with surgery is the most widely used treatment alternative. Although low recurrence rates are observed with [10][11][12] or without 13 a defined surgical technique, mitomycin C, the most frequently used antimetabolite in pterygium treatment, has limited value owing to its potentially toxic effects.…”

The Efficiency of Limbal Conjunctival Autografting in Pterygium Surgery

“…It was reported that increasing age was associated with fewer recurrences in patients who underwent conjunctival autograft (7). On the other hand, the mean ages of patients with recurrence in the studies by Lewallen, Simona et al, and Dadeya et al were 29, 38, and 27 years, respectively (8,39,46). Guler et al reported that all recurrences occurred in patients who underwent limbal conjunctival autografting who were below the age of 40 years (45).…”

“…Since presence of Tenon's capsule in the graft may cause transient postoperative graft edema or retraction of the graft, attention should be paid to dissect this capsule from both the donor conjunctiva and the receptor bed (39,46). We injected an adequate amount of saline into the space between conjunctiva and Tenon's capsule.…”
