Retrobulbar hemorrhage.

Retrobulbar hemorrhage associated with retrobulbar anesthesia has been construed as a contraindication to cataract surgery. Cancellation of the surgery results in disappointment for both the patient and surgeon. A retrospective study of 60 eyes was undertaken to evaluate the safety of proceeding with small-incision phacoemulsification surgery after retrobulbar hemorrhage when specific criteria are met. If digital massage achieved a soft globe that was easily retropulsed and the eyelids were loose and easily mobilized, the surgery was performed as scheduled. If the globe remained firm within a tense orbit and proptosis with tight lids was present, surgery was cancelled. Fifty-seven cases with retrobulbar hemorrhage met these criteria and underwent phacoemulsification with implantation of a posterior chamber intraocular lens. The lack of intraoperative and postoperative complications suggests that small-incision cataract surgery can be safely performed when preceded by a limited retrobulbar hemorrhage.

Retrobulbar hemorrhage.

Retrobulbar hemorrhage is a rare complication of orbital trauma or surgery. Although the process is usually self-limiting, infrequently visual impairment may result. Various methods for relieving the associated intraocular hypertension (caused by the extraocular compression posteriorly) have been suggested. The effectiveness of some remains questionable. To reassess the effectiveness of conservative management of this problem, we reviewed the medical records of all 10 patients who had had retrobulbar hemorrhage at our institution during the past 8 years. Additionally, we did an experimental study on rabbits to evaluate the visual effects of a transient but abnormally high intraorbital pressure. The results are reported.

Central retinal artery occlusion without retrobulbar hemorrhage after retrobulbar anesthesia.

Four patients had central retinal artery occlusions after retrobulbar anesthesia with lidocaine HCl was administered before photocoagulation. One of these four had two separate episodes of closure. Only one had permanent visual loss, and none had evidence of retrobulbar hemorrhage. Each patient had a severe hematologic or vascular disorder. We think that direct trauma to the central retinal artery behind the globe, the pharmacologic or compressive effects of the injected solution, or both caused the occlusions in these patients.

Delayed suprachoroidal hemorrhage mimicking acute retrobulbar hemorrhage.

The signs and symptoms of an acute retrobulbar hemorrhage include sudden ocular pain, explosive unilateral proptosis, limitation of extraocular movements and loss of vision. Retrobulbar hemorrhage is a well-described complication of retrobulbar anesthetic injection. We report an unusual case of a presumed acute retrobulbar hemorrhage following intraocular surgery which, on further testing, was found to be a delayed suprachoroidal hemorrhage.

A simplified technique of orbital decompression for severe retrobulbar hemorrhage.

Severe retrobulbar hemorrhage may occur as a complication of a retrobulbar injection or from blunt or sharp injury to the orbit during an orbital or periorbital operation. When the patient with a severe retrobulbar hemorrhage does not respond to intermittent ocular massage, or paracentesis, or a lateral canthotomy, prompt orbital decompression becomes necessary. A simple and effective surgical technique that is applicable in such urgent situations was used in this study. The procedure does not entail waiting for computed tomography or the availability of an orbital surgeon and requires only minimal local anesthetics. A small mosquito clamp is inserted into the orbit through a small opening in the inferior fornix. The clamp is advanced into the orbit along the medial orbital floor until a depth of about 20 mm is reached. Pressure is applied to the clamp to break the orbital floor and maxillary sinus mucosa, and to decompress the orbit. I successfully used this technique on five patients in the past five years.

Retrobulbar hemorrhage after 12,500 retrobulbar blocks.

To determine the incidence of hemorrhage after retrobulbar nerve block, 12,500 consecutive cases were reviewed. Fifty-five retrobulbar hemorrhages occurred after retrobulbar injection, a prevalence of 1 in 227 (0.44%). This compares favorably with the quoted prevalence of 1%-3% in the literature. Acquired vascular disease was a significant risk factor (P < 0.017). Surgery was postponed in 41 (75%) of the cases in which a hemorrhage developed. Although retrobulbar hemorrhage is considered a serious complication of retrobulbar anesthesia, the eventual visual outcome after surgery in these patients was not significantly different from the control group.

Retrobulbar hemorrhage: a case report.

Retrobulbar hemorrhage is a rare complication that may occur after mid-face injuries or following soft and hard tissue surgery around the eyes. The cardinal signs and symptoms of retrobulbar hemorrhage are pain, diplopia, ophthalmoplegia, a progression of increasing proptosis, and decreasing visual acuity leading to blindness. The diagnosis can be confirmed with computed tomography (CT) of the orbit or with ocular ultrasound. These diagnostic images are also important to define the size of the hematoma. This report describes a traumatic retrobulbar hemorrhage. In this case there were no signs of acute visual loss, and conservative treatment was possible without surgical intervention.

Retrobulbar hemorrhage following strabismus surgery.

Retrobulbar hemorrhage, although a well-known complication of retrobulbar injection, periocular injections, and periocular surgeries, is not routinely associated with strabismus surgery. We present a case of delayed orbital hemorrhage occurring in a young boy 2 days after strabismus surgery.

Spontaneous retrobulbar hemorrhage in type IV Ehlers-Danlos syndrome.

PURPOSE: To describe a case of spontaneous retrobulbar hemorrhage in type IV Ehlers-Danlos syndrome, a disorder characterized by vascular fragility and associated severe bleeding problems. METHODS: Observational case report. Spontaneous unilateral retrobulbar hemorrhage in a 22-year-old man with type IV Ehlers-Danlos syndrome was documented by clinical and radiographic examination. RESULTS: The retrobulbar hemorrhage was self-limited and resolved without visual sequelae. CONCLUSION: Spontaneous retrobulbar hemorrhage should be recognized as part of the spectrum of type IV Ehlers-Danlos syndrome, and clinicians must be alert to diagnosis and treatment of this vision-threatening problem.

Traumatic retrobulbar hemorrhage: emergent decompression by lateral canthotomy and cantholysis.

Traumatic retrobulbar hemorrhage may result in acute loss of vision that is reversible when recognized and treated promptly. A case of traumatic retrobulbar hemorrhage is presented. The technique of emergent orbital decompression by lateral canthotomy and cantholysis is described. The anatomy of the lateral canthus and the surgical procedure are illustrated by gross dissection.

Visual recovery following immediate decompression of traumatic retrobulbar hemorrhage via transcranial approach.

A 17-year-old boy presented with retrobulbar hemorrhage manifesting as right proptosis, periorbital swelling, and blindness after suffering a midfacial trauma. Immediate decompression by removal of the retrobulbar hemorrhage via the transcranial approach was performed. The proptosis was resolved and visual acuity and eye movement were restored. Retrobulbar hemorrhage is a serious injury which may lead to blindness. However, recovery from blindness can be achieved with adequate management including neurosurgical decompression in the early stage.

Retrobulbar hemorrhage nine days after cosmetic blepharoplasty resulting in permanent visual loss.

A healthy 45-year-old man had a retrobulbar hemorrhage 9 days after cosmetic upper eyelid blepharoplasty that resulted in permanent visual loss. After performing a left lateral canthotomy and cantholysis, intraocular pressure returned to normal and vision improved from no light perception to 20/40; however, the patient did have permanent visual field loss. To our knowledge, this is the longest period of time after blepharoplasty that a retrobulbar hemorrhage occurred. Ophthalmologists should have a heightened level of suspicion 1 to 2 weeks after surgery.

Diagnosis and treatment of retrobulbar hemorrhage.

Complete loss of light perception in an eye is one of the most severe complications of maxillofacial surgery. Although irreversible in many cases, early recognition and prompt intervention may improve the final outcome. The purpose of this article is to review the etiology and pathophysiology of retrobulbar hemorrhage, and discuss its diagnosis and management.
