There are many methods described for the surgical treatment of pterygium. However, none of the operations have been free from recurrence.

A new technique which is simple, economical with least recurrences is being described.


  Material and Method Top


This presentation comprises follow up study of 41 cases of nasal Pterygium performed by the technique described below.

Steps of my operations:­

1. Local anaesthesia;

2. Complete separation of Pterygium

3. Separation and removal of the fiasy mass of Pterygium under the conjunctiva.

4. A horizontal strip `B' 4 mm x 1 mm is dissected from the central part of the pterygium and preserved in normal saline.

5. Remaining parts of the Pterygium `A' & `C' are cut & thrown.

6. A vertical strip of 4 mm x 1 mm of episcleral tissue with superficial lamellae of sclera is dissected out 3 mm from the limbus. Resulting gap is shown as `D' in the diagram. This is to cut away the feeding blood vessels of the Pterygium.

7. Strip `B' of the Pterygium which was preserved in the saline is now transplanted as free graft near medial canthus just medial to the gap `D'. 5 stitches with 8/0 virgin silk taken to flx the graft. Thus graft `B' which was horizontal originally is now vertical in new set up and-it becomes fibrous band in due course and prevents further recurrence of Pterygium.

Dressing:-8 Days First day with Neosporin, Gentamycin and Atropine Drops. Next 3 days with Neosporin and Gentamycin Drops. Last 4 days Genamycin drops & Chlorocort Ointment. Stitches to be removed on 8th day. Longest follow up is nearly one year now.


  Observations & Discussions Top


In this study of 41 cases, 57% were females and 43% were males. Maximum incidence of pterygium was in the age group of 20-30 yrs. Youngest patient was of 20 yrs. & oldest patient was of 55 years. Maximum follow up is about 1 year, and pterygium recurred in 2 cases

(8.5%).

It is a simple and effective technique in checking the recurrence. Its effectivity is due to:­

a) The feeding blood vessels of the pterygium are cut with episcleral dissection.

b) Originally horizontally situated Ptery­gium tissue is transplanted vertically which forms fibrous band between growing tissue and the cornea so future growth is strangulated.
