Retinal arteriolar obstruction with progestogen treatment of threatened abortion.
OBJECTIVE
To describe a case of a retinal arteriolar occlusion associated with progestogen treatment of threatened abortion.


METHODS
Case report.


RESULTS
A 30-year-old woman who had received a 2-week course of high dose intramuscular progestogen for a threatened abortion presented with a paracentral scotoma in her right eye and occlusion of a small arteriole adjacent to the macula. There were no major subsequent variations in haemostasis and pre-existing systemic diseases were excluded.


CONCLUSIONS
Retinal arteriolar occlusion may be associated with high dose progestogen-only therapy in pregnant women.
