FIELD: medicine.SUBSTANCE: invention relates to medicine, namely to ophthalmology, and can be applied for treating recurring pterygium of large sizes based on autoplasty. Obtained technical result consists in reduction of defect size of bulbar conjunctiva, which provides possibility of effective treatment of recurring pterygium of large sizes based on autoplasty due to selection of required size of transplant, capable of covering conjunctival defect, obtained after dissection of pterygium body and head. After excision of pterygium body and separation of pterygium head bulbar conjunctiva in zone of pterygium excision on defect edge is sutured with blanket suture, after which thread is tightened, with formation of considerably smaller in size bulbar conjunctiva defect. From lower-external part of conjunctival fornix donor tissue for transplant formation is cut out. As donor tissue section of conjunctiva is applied. Size of transplant is calculated taking into account size of obtained conjunctival defect. Transplant is placed on sclera in place of pterygium body excision and fixed with uninterrupted suture to own bulbar conjunctiva.EFFECT: invention solves a problem of developing novel method of treating recurring pterygiums of large sizes based on autoplasty. |
