Spots on the eye can be several different conditions, and the risks involved depend on what the spot is or what it is suspected to be. It is not possible to give a diagnosis based on a photograph, and hence you need to see a doctor if you want to know the risks specifically for your situation.
The following answer applies to conjunctival nevi. I would like to emphasise again that this may not apply in your case and you need to see a doctor for a full consultation first.
Conjunctival nevi are 'moles' or 'freckles' on the surface of the eye, and are in most cases benign. Their removal is usually elective/optional and involves a small surgical procedure to remove them. If the nevus is large, a conjunctival graft may be taken from another part of the eye to cover the operated area.
The risks of operating on it are minimal and includes:
- Mild local scarring
- Residual pigmentation
- Mild bleeding (subconjunctival haemorrhage)
- Infection
If spots are obviously growing larger or becoming darker in colour, it becomes more urgent to see a doctor and have the lesion removed so that it can be checked by a pathologist under the microscope, to determine its exact nature.
