Most small scleral wound leaks at the limbus are treated successfully with suturing, patching, bandage lenses, or cyanoacrylate adhesive, but occasionally a wound leak may continue and a fistula may develop. Although rare, most such fistulas are usually associated with cataract surgery or trauma. Failure of a scleral fistula to close may be due to epithelialization or chronic necrosis of the lumen. In three cases, persistent fistulas of the limbal sclera were excised with a trephine, and a peripheral graft using corneal donor tissue was used to seal the circular defect. This resulted in permanent wound closure and provided a tissue diagnosis of epithelial downgrowth (2 cases) and chronic scleral necrosis (1 case).
大多数位于角膜缘的小巩膜伤口渗漏通过缝合、修补、绷带镜或氰基丙烯酸酯粘合剂治疗成功，但偶尔伤口渗漏可能持续存在并形成瘘管。虽然罕见，但大多数此类瘘管通常与白内障手术或外伤有关。巩膜瘘管未能闭合可能是由于管腔内上皮化或慢性坏死。在三例病例中，用环钻切除角膜缘巩膜的持续性瘘管，并使用角膜供体组织进行周边移植以封闭圆形缺损。这导致伤口永久闭合，并提供了上皮内生（2例）和慢性巩膜坏死（1例）的组织诊断。
