    9 Rarely, fracture of the orbital roof, orbital hemangioma, and epibulbar dermoid may cause haemolacria if the conjunctiva is openWhen we came down, we had to come back for the six week ultrasound, because we had four embryos implanted, that was before they cut down on how many you could have put back, there were two heart beats
