Purpose Acute angle-closure glaucoma is a common ophthalmic emergency and individuals with shallow anterior chambers and suspected narrow angles are increasingly referred to the hospital eye service for assessment. There appears to be variation in subsequent management, with no national consensus or college guidelines. This study ascertains the current use of prophylactic YAG iridotomy in patients with no known history of an acute angle-closure glaucoma attack, and also the methods used in patient selection.

Mucocoeles are cyst-like lesions of the paranasal sinuses, which may rarely erode through the bony orbit and so displace or compress orbital contents. Such patients may present to ophthalmologists and other health care professionals with diverse problems including facial pain and swelling, proptosis, double vision, ptosis, infra-orbital anaesthesia, epiphora and optic nerve dysfunction with reduced vision. We present an illustrated interventional case report of an 81-year-old gentleman with a 2-week history of swelling around the left lower eyelid and malar region associated with double vision both in the primary position and particularly downgaze. We discuss the aetiology, diagnosis and contemporary management of maxillary mucocoeles and also the Caldwell-Luc procedure. The article serves as a reminder that maxillary mucocoeles may slowly and covertly invade the orbit and should be considered in the differential diagnosis in patients presenting with proptosis, globe displacement and an orbital or adnexal mass.

A 65-year-old man with sudden profound loss of vision in his right eye due to sub-periosteal orbital haemorrhage was found to have disseminated intravascular coagulation (DIC) secondary to metastatic prostatic carcinoma. CT-scan did not reveal any orbital metastases. A lateral canthotomy did not help to restore the vision. Orbital haemorrhage is known to occur with DIC due to different causes. To the best of our knowledge this is the first report of orbital haemorrhage with DIC related to prostatic carcinoma. This case emphasises the importance of considering systemic factors in cases of non-traumatic haemorrhage, along with imaging studies to rule out any co-existing vascular anomaly.
