Surgical treatment of pterygium

Abstract

Pterygium is one of the modern problems of ophthalmology. The exact etiology and pathogenesis of this disease has not been reliably established and, as a result, there is no universal method for its recurrence-free treatment. The literature data on various methods of pterygium surgical treatment such as 'bare sclera', conjunctival autograft, limbal stem cells transplantation techniques, amniotic membrane plasty and other methods was analyzed. The advantages and disadvantages of those surgery methods were identified. With consideration of the new data on proliferative nature of the disease, the results of adjuvant treatment of pterygium using cytostatics and anti-VEGF drugs were examined. Introduction of new technologies for the treatment of pterygium in practical health care can significantly improve the effectiveness of surgeries, reduce the incidence of postoperative complications and the number of relapses of the disease.

Ologen Implantation versus Conjunctival Autograft Transplantation for Treatment of Pterygium

“…The prevalence of pterygium was 3.7% in northern China and 37.4% in southern China [ 14 ], which suggested that ultraviolet exposure and ultraviolet radiation were important risk factors [ 15 ]. Up to now, surgery was the main treatment for pterygium [ 16 ]. Fibrosis causes adherence of the conjunctiva and Tenon's capsule, which may lead to recurrence, and it is dependent on the patient's inflammatory response [ 17 ].…”

Limbal-conjunctival Autograft Transplantation Versus Conjunctival Autograft Transplantation In The Treatment Of Pterygium: A Self-control Study

“…However, although there are various surgical methods for the treatment of pterygium, there has been no consensus yet on which surgical method is the best choice [1][2][3]. The recurrence rate of pterygium is the main challenge for ophthalmologists [4,5]; therefore, it is important to choose the most appropriate and effective surgical method for the treatment of pterygium [6,7]. Common surgical techniques include simple pterygium excision, conjunctival autograft transplantation, pterygium transposition, pterygium excision combined with amniotic membrane transplantation, limbal-conjunctival autograft transplantation, and adjunctive therapies such as use of mitomycin C, anti-VEGFs, or antibrotics.…”
