Recurrent Pterygium may be considered a common side effect of pterygium surgery. If the pterygium is removed but no attention is paid to removing the scaffold of tenon’s capsule, nor adjunctt therapies used – there is up to a 70% chance of recurrence. Recurrent Pterygium management is an art and sequence. We end up helping a lot of these patients who had their primary pterygium surgery elsewhere. Pterygium are like weeds. Either behead them, kill them completely or leave them alone. Never prick, sword or irritate them. For then they attack savagely.
Recurrent Pterygium is worse than the original one because they can spread in all directions and have more fibrosis. It means they are more firmly attached to the muscles and surrounding eye tissue. They are also more vascular. The blood vessels supply it the nutrition in its march to conquer territory it had lost before.
