Tenonplasty for closing defects during sclerocorneal surgery—A brief review of its anatomy and clinical applications

Abstract

To provide insight into the clinical anatomy of Tenon's capsule and to describe a technique to manage sclerocorneal defects using autologous Tenon's tissue. A thin layer of Tenon's capsule harvested from the patient's own eye is used to seal the defect and act as a scaffold. The Tenon's flap is spread over the defect and held in place by Vicryl sutures. A bandage contact lens is then placed on the eye. Tenon's capsule is composed of thick fibrous tissue with smooth muscle fibers and a thin posterior capsule of orbital fat. It is rich in fibroblasts, which can accelerate wound healing and eventually lead to robust scarring without risk of immunogenicity and without cost. Tenonplasty uses easily-available autologous Tenon's tissue in patients with sclerocorneal defects to preserve globe morphology. The technique is a feasible alternative not limited by the availability of graft tissue. Clin. Anat. 31:72-76, 2018. © 2017 Wiley Periodicals, Inc.

Curcuma longa aqueous extract: A potential solution for the prevention of corneal scarring as a result of pterygium surgical excision (Review)

“…There is no clear-cut single treatment of choice for removing either a primary pterygium or recurrent pterygium; although there are several possible surgical methods (22), there is a high likelihood of sclerocorneal scarring as a result of surgical excision (24). If the scarring extends close to the visual axis, irregular astigmatism and reduced visual function may occur as a disabling complication of the surgery.…”

Tenon Patch Graft With Vascularized Conjunctival Flap for Management of Corneal Perforation

“…For limbal perforations, a rotational flap has been advocated, which draws on the vasculature of Tenon and allows for conjunctiva to grow onto the surface. 5,6 A "tuckin" approach has been demonstrated for incisions up to 5 mm in diameter, using a stromal pocket and tucking in the Tenon into the stroma surrounding the perforation; reported outcomes have been encouraging with mean duration of healing of 25.7 days. 7 Tenon tissue can also be tucked into the plane of corneal wound burn incisions from cataract surgery to facilitate wound plugging and fibrosis.…”
