Guest guest Posted February 17, 2008 Report Share Posted February 17, 2008 is this usually from lyme? it mentions bug bites at the end how to get diagnosed and treated, does it show up on scans or swabs cellulitis, orbital and periorbital These terms refer to bacterial infection of the tissue layers under the skin (cellulitis) around the eye - periorbital cellulitis - and sometimes in the deeper structures around and behind the eyeball - orbital cellulitis. The terminology of orbital and periorbital has been clarified by the more specific reclassification of these infections into pre-septal and post-septal categories, based on where around the eye they occur. The septum is a seal that circles the globe of the eye, separating the mucous membranes of the lids and the schlera (white covering of the eyeball) from the deeper attachments of the eye muscles. The orbital septum is a watershed divide that determines which way the veins drain - directly back to the body circulation through facial veins or into the brain area (intracranial cavity). Because of anatomic factors discussed below, cellulitis of the eye region is referred to as either pre-septal or post-septal. So-called preseptal (or periorbital - " around the eye " ) cellulitis is a bacterial inflammation of the tissues around around the eye and eyelid. This infection produces marked swelling and tender redness around the eye, but there are no signs of limitation of movement of the eye. Preseptal or periorbital cellulitis is much less serious than its postseptal counterpart, and is much more common. True orbital cellulitis (post-septal, behind the septum) is a very dangerous infection because germs have direct access to the brain through the veins that drain the eye region. Entry of bacteria into the brain and spinal fluid system would result in dangerous bacterial meningitis. Ophthalmoplegia - limitation of the movements of the eye - is the frightening hallmark of this infection. Because of the danger of developing into widespread blood-born or central nervous system infections, infections around the eye are often treated intravenously in the hospital. True orbital cellulitis requires very aggressive intravenous antibiotic therapy, and generally speaking, only the milder periorbital (preseptal) infections are treated orally. The spectrum of causative germs for orbital and preseptal cellulitis has changed radically in recent years. Orbital cellulitis infections used to be classically caused by Hemophilus influenza type B, as a complication of a sinus infection with the Hemophilus bacterium, whereas preseptal or periorbital cellulitis was classically a strep or staph infection as a complication of a bug bite. Hemophilus infection has disappeared with the H. influenza vaccine (HiB). Now the predominant causative germs for both pre- and post-septal cellulitis are Streptococcus and Staphylococcus species. amy Quote Link to comment Share on other sites More sharing options...
Guest guest Posted February 17, 2008 Report Share Posted February 17, 2008 Can be all kinds of things. This article primarily associates the bug bites with staph infection, which makes total sense to me (staph can be carried by mosquitos, just like lyme can), but it also mentions viruses and could really be any kind of bug that manages to take hold in your body. Unfortunately for us, our sinuses are very convenient entry points for bugs. This is timely for me as well, as my daughter's eye has been watering non-stop for about a week now. I've been telling her she's probably got an infection, but she's been doing her own research and considering other possibilities based on conventional thought of allergies, etc. Anyway, she finally found her own info on the link between the eye watering and infection of the sinuses and tear ducts. Although we're already planning to go to the doctor on monday (since eye infections can be dangerous) she finally couldn't take it anymore and took one of the zillion broad spectrum abx I have around here. Sure enough, eye watering started reducing almost immediately and what do you know, her sinuses suddenly started acting up like crazy, while there seemed to be no involvement at all before! Her sinuses are definitely in whatever is causing her eye to water and fortunately she's definitely responding to the abx. I am convinced that ALL of this stuff is related to infections getting into our head & neck regions and it drives me crazy that the medical world is so lax in it's recognition of the problem. My daughter's college psych teacher believes that numerous diseases, including psychiatric ones, are caused by bacteria. When the HELL are other people going to figure this out????!!!!! penny amydent9 <amydent9@...> wrote: is this usually from lyme? it mentions bug bites at the endhow to get diagnosed and treated, does it show up on scans or swabscellulitis, orbital and periorbitalThese terms refer to bacterial infection of the tissue layers underthe skin (cellulitis) around the eye - periorbital cellulitis - andsometimes in the deeper structures around and behind the eyeball -orbital cellulitis.The terminology of orbital and periorbital has been clarified by themore specific reclassification of these infections into pre-septal andpost-septal categories, based on where around the eye they occur.
