2. Occular complications:<br />
Review ofLiterature<br />
According to Richards (1986) , only IM3% ofcases ofPIH and<br />
eclampsia suffer from temporary blindness due to one ofthe following<br />
causes:<br />
MCentral retinal arteriolar or venous thrombosis.<br />
MEdema ofthe retina.<br />
MCentral disturbance of the visual center in the occipital lobe by edema or<br />
hemorrhage.<br />
MDetachment ofthe retina.<br />
- Disturbance ofthe optic nerve.<br />
- Psychogenic disturbances.<br />
- Intracranial venous thrombosis.<br />
3. Rena/complications:<br />
Acute renal failure is an extremely rare complication of P.I.H<br />
eclampsia and its development is usually a result ofeither acute tubular<br />
necrosis or rarely bilateral cortical necrosis.<br />
The pathogenesis ofacute renal failure continues to be the subject<br />
of extensive investigations and several pathologic mechanisms have been<br />
implicated as possible etiologic factors. The occurrence ofacute renal<br />
failure is usually associated with P.I.H complicated by abruptio placental<br />
and disseminated intravascular coagulopathy (DIC) (Sibai et aI., 1990) .<br />
Therapeutic principles in the management of acute renal failure<br />
include supportive and dialytic treatment until renal function recovers.<br />
Once the maternal condition is stabilized, if the fetus is mature, delivery<br />
should be effected. Successful peritoneal dialysis and hemodialysis have<br />
been reported for the treatment of acute renal failure in pregnancy.<br />
Peritoneal dialysis is associated with a lower risk of hypotension and<br />
rapid fluid shifts. (Hov, 1987).<br />
