Review Case Reports
Allergic fungal sinusitis involving the lacrimal sac: a case report and review.
BACKGROUNd: We report a case of allergic fungal sinusitis (AFS) involving the lacrimal sac and review the current English literature. A literature search for AFS involving the lacrimal sac revealed two reports with only one of the two cases demonstrating histological evidence of fungal elements. This is just the third such case and only the second reported case with histopathologic confirmation of fungal elements by Gomori methenamine silver (GMS) stain. ⋯ Although rarely reported, AFS can affect the lacrimal sac. AFS should be suspected in patients with a history of recurrent refractory sinusitis, recurrent dacryocystitis and nasal polyposis. Early diagnosis is important for adequate treatment and prevention of recurrence.

The current dogma is that the oculocardiac reflex from orbital trapdoor fractures occurs only in children and young adults. We present the occurrence of the oculocardiac reflex in an adult with a non-displaced orbital floor fracture. CT demonstrated the adventitia surrounding the inferior rectus trapped in and below the orbital floor fracture. The patient's oculocardiac reflex resolved by early next morning, presumably from the tissue escaping from the orbital floor defect.

Comparative Study
Porous orbital implant exposure: the influence of surgical technique.
To examine orbital implant exposure rates following enucleation and evisceration. ⋯ Orbital implant exposure remains a significant cause of morbidity in patients undergoing enucleation and evisceration. Rates of orbital implant exposure were significantly lower when surgery was performed by an orbital surgeon. Differences in surgical technique are the most likely explanation.

A 43-year-old man was struck in the left orbit with his board while surfing and sustained a 3-cm laceration above his left eyebrow. The laceration was sutured closed primarily at a local emergency room. When he presented to UCSD oculoplastics for suture removal, he complained of diplopia with upgaze and was found to have hypoglobus on clinical exam. ⋯ The patient underwent surgical exploration. A 55-mm-length piece of fiberglass from the patient's surfboard was removed from his orbit. This case demonstrates the importance of having a high index of suspicion for retained orbital foreign bodies, regardless of the size of the object inflicting the injury.

A 72-year-old male presented with progressive right axial proptosis and red eye. Catheter angiography demonstrated an intraorbital arteriovenous fistula (IAVF) distal to the central retinal artery (CRA). Transvenous embolisation following direct surgical exposure of the superior ophthalmic vein (SOV) resulted in rapid resolution of his symptoms and signs. Transvenous embolisation via the SOV is a safe, effective alternative to transarterial embolisation for treating spontaneous IAVF where transarterial embolisation poses a risk of CRA occlusion.
