Recurrent Self-Induced Nontraumatic Orbital Emphysema Causing Orbital Compartment Syndrome with Optic Nerve Dysfunction.

The majority of cases of orbital emphysema are due to trauma. Complications are rare, and therefore, the need for surgical intervention is uncommon. We present the first case of which we are aware in which nontraumatic orbital emphysema led to orbital compartment syndrome and subsequent optic nerve dysfunction.

Orbital Crystal-Storing Histiocytosis: A Clinicopathologic Study of 4 Cases.

The authors report the clinicopathological features of crystal-storing histiocytosis (CSH) that involved the orbit and conjunctiva and review published cases of CSH. Cases of histologically proven CSH were identified from archives at the Institute of Ophthalmology, London, and a retrospective review of clinical details and pathology was performed for cases between 1997 and 2017. Four cases of CSH were identified: 1 might have arisen from an inflammatory reaction to a silicone retinal buckle and 3 others occurred with localized B-cell lymphomas.

Complications and outcomes of grafting of posterior orbital fat into the lower lid-cheek junction during orbital decompression.

Purpose: To report the complications of grafting of excised posterior orbital fat into the lower lid-cheek junction at the time of orbital decompression surgery.

Methods: Retrospective review of consecutive patients undergoing orbital decompression combined with grafting of posterior orbital fat to the pre-malar and lateral canthal area (FG). A second group of consecutive patients undergoing orbital decompression but no orbital fat grafting (NoFG) were also studied as a form of comparative control.

Effect of Manuka Honey on Eyelid Wound Healing: A Randomized Controlled Trial.

Purpose: To report outcomes of a randomized trial on the role of "active" Manuka honey on eyelid surgical wound healing.

Method: Prospective, randomized, single-blinded study was performed for patients undergoing bilateral upper blepharoplasty. Vaseline was applied 4 times a day to both sides for 6 weeks and in addition, one eyelid was randomized to receive Manuka honey twice daily.

The Mechanics of Brow-Suspension Ptosis Repair: A Comparative Study of Fox Pentagon and Crawford Triangle Techniques.

Purpose: To perform quantitative analysis of the most commonly used brow-suspension configurations.

Methods: The inflection positions for Fox pentagon and Crawford triangle configurations were marked on 49 healthy volunteers (male and female) and photographs taken in 3 states: "normal," "closed," and "raised." The skin marks were measured vectorially with respect to the medial canthus, and displacement changes were evaluated for "normal-to-closed" ("blinking") and from "closed-to-raised" ("eye-opening") states.

Platinum segments: a new platinum chain for adjustable upper eyelid loading.

Purpose: Prospective study evaluating outcomes of individually sutured platinum segment chains in upper eyelid loading.

Methods: Single-centre, single-surgeon, prospective study. Upper eyelid loading with 0.

Post-operative orbital imaging: a focus on implants and prosthetic devices.

Accurate interpretation of orbital imaging in the presence of either orbital implants requires a sound knowledge of both the surgical approach used and the imaging characteristics of the implanted devices themselves. In this article, the radiological appearance of the various devices used in ophthalmology, and their relationship to other orbital structures, is reviewed. In addition, the intended anatomical location, function of these devices, and clinical indications for their use are provided.

Medpor lower eyelid spacer: does it biointegrate?

Purpose: To report the histopathologic findings of explanted Medpor lower eyelid spacers (LES) in complicated cases.

Materials And Methods: Four cases of lower eyelid retraction due to thyroid orbitopathy (n = 2), facial nerve palsy (n = 1), and post-enucleation socket syndrome (n = 1) were treated with Medpor LES.

Results: All implants were removed between 6 months to 2 years following their original insertion due to exposure, poor stability, or contour.

Multiple intracranial aneurysms presenting with epistaxis.

Although epistaxis secondary to rupture of a post-traumatic, false aneurysm is well documented, true intracavernous carotid artery aneurysms presenting with epistaxis are very rare. We present such a case in a patient with multiple aneurysms. The aneurysm was treated by endovascular techniques and the patient made a good recovery.

Periocular necrotising fasciitis--a case report.

Purpose: To document the step-by-step reconstructive surgical rehabilitation, over a 12-month period, of a patient with severe periocular necrotising fasciitis.

Methods: This is a retrospective interventional case note review of a 68-year-old man who developed necrotising fasciitis a few days after an insect bite. He had severe facial cellulitis with subsequent necrosis of all four eyelids despite broad spectrum antibiotics.
