







Plain Pterygium (Pterygium excision)
Pterygium excision with MMC
Pterygium excision with MMC with clag
Pterygium with AMG
 Pterytgium Excision: (Plain Pterygium)
The Pterygium (the fleshy growth) is
removed from the eye
 Pterygium excision with MMC:
 Pterygium is removed and replaced with
mitamycine gel
 It reduces the regrowth of the pterygium
Cont….
 Pterygium Excision with MMC with clag:
 Pterygium is removed and midamycine is
placed in conjunctival auto graft
 This reduces the regrowth of Pterygium
 This is of two types
1. Suture method
2. Glue method
Suture method
Conjunctival auto graft placed in the
sutures
Glue method (Fibirin glue)
 In this method the gel used is Fibirin gel
 It is placed on the conjunctival autograft
without sutures
 It is used because of the reduced regrowth
of the Pterygium and reduced irritation of
the eye
Pterygium excision with AMG
Pterygium is removed and the aminotic
membrane is placed in it
Role of the counsellor
 It should be stressed that permanent vision loss
may occur if it grows very large over the cornea
even if surgery is done at this stage
 The only permanent treatment is surgery ideally
with an auto from the same eye
 Topical medication only can temporarily allay the
symptoms
Cont….

the growth in the eye if the growth is very
small
