EXPERIENCE: none OPINION: Might be helpful to distinguish between VASCULAR vs BAROTRAUMA etiologies. VASCULAR - might include vasculitis, both postinfectious and immunologic; and are less likely related to HRT effects. On the other hand, thrombophilia (including rheologic {hyperlipidemia/hypertriglyceri- demia}, and acquired {diabetic retinopathy/antiphospholipid syndrome} or congenital {protein c/s, AT-III, Leiden factor V (resistance to activated protein C - recently presented for discussion here on our list)}) -- may well be influenced by HRT. This may be particularly related to mode of estrogen administration (hepatic cofactor & triglyceride production). BAROTRAUMA - or microbubble air emboli secondary to less than optimal decompression, can occur sporadically, and unpredicatably at times, (particularly, even at quite shallow depths in pts. with asthma - which she likely does not have). This would likely present shortly following a dive, and may be assoc with other vaso-occlusive phenomena. It would not be likely to be related to HRT. ADVICE: Insure the input of an interested Ophthalmogist. May be some role for color doppler in determinig etiology, as well as recurrence rates both ipsi-, and contralaterally. ADDITIONAL POINT: Regarding air embolism (+/- doppler!) anybody have any comments regarding findings from Sept. 1993 Anesth.Analg. (Vol 77: 448-52), regarding rel. high incidence during c/s?

The American Medical Association is no longer designating CME hours for AMA Category II CME credit. However, physicians themselves may self designate learning activities as Category II CME credit hours if they feel it is of sufficient educational merit and meets the formal definitions of continuing medical education. OBGYN.net believes these interaction in this forum meets these criteria. For further information see the AMA web site.
