Natasha, it could be a Charlaztiom (spelling is off) look it up. I had one before, I had a lump in the corner of my right eye.. Closest to my nose. I used apple cidar vinegar mixed with warm water. Put it in a small cup and put your eye to the rim of the cup and blink, so the water and apple cidar vinegar mixture can flush in/out your eye. Also try taking at least a tablespoon of pure apple cidar vinegar once a day by mouth. It’s known for natural antifungal properties as well as healing. Hope this helps some of you! I didn’t see it mentioned, but it really helped me. I did it twice a day. Also warm black tea bags applied like a compress will help.
You are exactly right in your thinking. Different drops are used to dilate eyes. Tropicamide (mydriacyl) is the most common drop and it comes in two strengths, % and %. The % will not last quite as long but it is not a large difference. Tropicamide will dilate the eyes and interfere with near focusing. Phenylephrine is often added as a second drop with mydriacyl to enhance the dilation. Phenylephrine enlarges and hastens the dilation but has no effect on focusing and usually does not prolong the dilation. Paremyd is another drop containing % hydroxyamphetamine and % tropicamide. It does not dilate the eyes as well but tends to last a shorter time period and not interfere with near focusing as much. Longer lasting drops include cyclopentolate and homatropine. They have a longer mode of action and exert significantly more interference with close vision. They are usually used for children.
Eye care practitioners can choose from an impressive and effective armamentarium of drugs to combat infectious diseases that are caused by bacteria. In most cases, a combination steroid-antibiotic agent is the best choice to address both the infection (or the threat of infection) and the inflammation that results from bacterial inhabitation. High-dose, potent antibiotic therapy should be reserved only for those serious infectious cases where the cornea is truly threatened and should never be used injudiciously because of the evergrowing risk of antibiotic-resistant organisms.
