What is Pterygium?
This is a fleshy growth on the white of
the eye (conjuntiva) on either side of the
cornea
It occurs in people exposed to excess
wind, heat sun and dust and can grow
over the cornea
In addition to being cosmetically
disfiguring. It can cause pain redness and
discomfort
Nasal Pterygium
Types of Pterygium
Nasal Pterygium
Temporal Pterygium
Double Pterygium
Nasal Pterygium:
The fleshy growth on the conjunctiva on Nasal
side is called Nasal Pterygium
Temporal Pterygium:
The fleshy growth on the conjunctiva on
Temporal side is called Temporal Pterygium
Double Pterygium:
The fleshy growth on the conjunctiva on Nasal
and Temporal side is called Double Pterygium
Treatment
All of the Pterygium patients does not require
surgery
Starting stage Pterygium patients are given
lubricating drops
Three types of Pterygium surgeries are
available
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….
Wearing the sun glass would help mitigate
the growth in the eye if the growth is very
small
And also giving the post operative instructions
Don’t take head bath
Don’t rub your eyes
Irritation is there, so don’t worry
Importance of correct method of using eye
drops
To come for regular follow up
