The fungal infection you have described is a relatively rare one. The most significant thing about this kind of an infection is that the reason it occurs in humans is not really known. Fusarium is a fungus that commonly involves soil and plants and the migration to the human eye is not clearly understood or even explained by medical science. This could be a possible reason why you are finding it difficult to zero in upon a precise method of treatment. Sadly, there is no cure for this infection either. It is even more puzzling that you have contracted it since you say you do not wear contact lenses. This is not even a transferrable infection which can spread upon contact. One of the only ways on checking the spread and growth of this infection is to manage an early detection. This way, you can at least save your eyes from complete blindness. If you have not managed to take any of the preemptive measures that help out in the situation, then you should be completely under medical care for your condition. It is unwise to try and treat yourself with home remedial measures for a disease that has no cause, no cure and about which too little is commonly known.
The best you can do is check the growth of the fungus by ensuring that you have the health and hygiene factor covered. Since you do not wear contact lenses, that is the one important thing you can leave out of your eye care routine. You should ensure that you are washing your eyes out with fresh water every day. This is one of the best ways to keep eyes healthy. In some ancient South East Asian cultures, honey is known to be an excellent tonic for the good health of your eyes. But there are some conditions attached to this. For instance, the honey should be local to your area and it also needs to be pure honey, as opposed to adulterated honey. If you can find this, only then should you try to put a drop in each eye. This will be a good measure for the general health of your eyes. If you can find aged honey, this is all the better. Please do keep in mind that honey really stings very badly when it comes in contact with your eye. This sting will last for about a minute after which you should be fine.
