Conjunctival Lymphatic Cysts

I have had this condition a number of times myself, and have seen it many times in my patients, but there is not a heck of a lot of information on the web about them. When you Google "conjunctival lympatic cyst" you get some generic ophthalmological definition like this: "Lymphatic cysts of conjunctiva. These are common and usually occur due to dilatation of lymph spaces in the bulbar conjunctiva. Lymphangiectasis is characterized by a row of small cysts. Rarely, lymphangioma may occur as a single multilocular cyst." from this link: http://ophthalmologylife.blogspot.com/2012/04/cysts-of-conjunctiva.html But what does that really tell you? It doesn't tell me anything, except it's a cyst (fluid-filled pocket) made from lymph (clear liquid from the lymph system). Ok, well that's not very helpful. A conjunctival lymphatic cyst is a clear liquid "bubble" on the surface of your eye:

It is not known how they come about, but in my experience I think they are somewhat related to ocular allergy. I could be wrong on this, but that's just my opinion. If someone finds me some better data on the cause of them, please feel free to post. Here's what we know about them: - they're usually small, clear "liquid bubbles" on the surface of the eye - they are benign - they usually go away on their own - if they don't go away, they can easily be surgically excised/lanced - they can be annoying as all get-out They can feel like a foreign body (i.e. "something in your eye"). Most patients who feel them (and I can tell you this from personal experience) say that they feel like there's constantly an eyelash in your eye that you need to get out...but you obviously can't. I treat them with antihistamine eye drops, since I believe that they are at least peripherally related to ocular allergy. Most of them go away. Whether they go away on their own or are helped (sped up) somewhat by ocular antihistamine usage, I don't know. From my own personal experience, they go away in approx 2-4 weeks.
