Management of acute surgical orbital haemorrhage: an otorhinolaryngological and ophthalmological perspective

Intraoperative intraorbital bleeding: considerations from a collaborative and retrospective Italian study with a management algorithm proposal

Background: Intraoperative intraorbital bleeding is a rare but potentially catastrophic event that can lead even to blindness, if not treated promptly. The goal of surgery is to quickly reduce intraorbital pressure thus restoring normal visual function. Aim of our work is to propose a practical algorithm helping the surgeon in the setting of this critical event. Methodology: An Italian multi-institutional retrospective study was conducted. All the cases of intraoperative intra-orbital bleeding requiring at least some form of surgical management were analyzed. Cases simply managed conservatively were excluded from this analysis. Results: Sixteen cases were collected. Of these, 12 were initially treated with a medial wall orbital decompression, while 4 were treated via a lateral canthotomy and inferior cantholysis (LCC). Ten patients recovered completely. Four patients presented post-op sequelae (diplopia, enophthalmous and/or eyelid malpositioning). Two major negative outcomes (blindness) were observed. Conclusions: Timely surgical intervention is critical. According to the setting in which the bleeding occurs, different options are available. LCC is probably the most rapid maneuver that can be done to reduce intraorbital pressure. Anyway, if the patient is still in the OR and a complete ethmoidectomy yet done we advise, as first step, to perform a medial orbital wall decompression.

Management of Retrobulbar Hematoma

Background

Retrobulbar hematoma (RH) is a complication that can result from both otolaryngic and ophthalmologic procedures. RH can occur during endoscopic sinus surgery and improper treatment can result in several morbidities, including visual loss. Despite serious consequences, management for RH is not well evaluated. However, lateral canthotomy with cantholysis is generally recommended. The objective of this study is to review the management for RH.

Methods

A retrospective study was performed at our tertiary hospital from 1979 to 2006 for patients with the ICD-9 code for orbital hematoma. The demographic information, comorbidities, presentation, management, follow-up period, and outcomes were evaluated. Data were analyzed.

Results

Twenty-two patients were identified with 13 male patients and an average age of 43 years (range, 11–80 years). The RH was broken into three categories: iatrogenic, six cases; trauma, eight cases; and spontaneous, eight cases. The most common symptom was diplopia followed by orbital pain. The average pretreatment and posttreatment tonometric pressures were 25.3 mm Hg (range, 11–60 mm Hg) and 14.5 mm Hg (range, 10–22 mm Hg), respectively. The average proptosis was 4.3 (range: 0–8) mm. Treatments were observation (13 cases), medical treatment alone (4 cases), and surgical treatment with and without medical treatment (5 cases). Sixty-eight percent of the patient's visual acuity improved with these treatments. Twenty-seven percent had no visual changes from the RH. The average follow-up was 5 years.

Conclusion

Traditionally, lateral canthotomy with cantholysis is recommended for the treatment for RH. However, in certain patients and settings, there may be an acceptable alternative option for the management of RH.

Sudden visual loss after uneventful cataract surgery: Snuff syndrome

We describe a case in which the patient had routine, uneventful cataract surgery and developed snuff syndrome on day 1 postoperatively. The patient had pseudoexfoliation syndrome and normal intraocular pressure that was well controlled by timolol and previous laser trabeculoplasty. Although the visual result had been good after surgery in the first (right) eye with a best corrected visual acuity (BCVA) of 6/5, this adverse event, which decreased the BCVA in the left eye from 6/24 preoperatively to hand movements postoperatively, was unexpected. Systemic evaluation failed to identify a specific cause. Data were collected prospectively on 1000 subsequent, consecutive cases of cataract surgery, but we were unable to find pathogenetic data on this occurrence.
