  Abstract 


Retrobulbar hemorrhage (RBH) is an ophthalmological complication with the potential risk of irreversible blindness due to the compressive effect on the optic nerve. Cases of patients with a history of antiaggregation and/or anticoagulation therapy and RBH have been reported in the literature; ophthalmologists should keep this antecedent in mind and consider the risk–benefit of surgery while working in conjunction with the area of anesthesia to establish the times when medication is suspended or initiated. Similarly, early and timely identification of signs and symptoms related to this complication improves patients' visual prognosis. The following describes the case of a patient who had RBH associated with the use of antiplatelet therapy.

  Introduction Top


Retrobulbar hemorrhage (RBH) is defined as the accumulation of hematic content in the retrobulbar space, which is behind the eyeball surrounding the optic nerve. RBH is a rare but devastating ophthalmological complication.[1],[2]

The etiology of RBH is diverse. It includes orbital trauma,[3],[4] ophthalmological or maxillofacial surgical procedures,[5],[6] arteriovenous malformations,[7] clotting disorders associated with systemic diseases,[8],[9],[10] and may appear as an adverse event due to anticoagulant or antiaggregate therapies.[11]

The overall incidence of RBH is estimated to be <1%. However, in the case of orbital fractures, the literature reports an incidence of 3.6% to 32.2%.[1],[4] Although RBH cases are low compared to other ophthalmological complications, the association between complete vision loss and RBH is between 29% and 48%.[1],[5]

The pathophysiology of this disorder is based on increased pressure in the orbit resulting in altered arterial circulation and venous return as well as mechanical compression of all structures. The different clinical manifestations that guide the diagnosis are derived from eye pain, diplopia, decreased visual acuity, decreased contrast sensitivity, sudden proptosis, ophthalmoplegia, chemosis, afferent pupil defect by compression of the optic nerve or occlusion of the central artery and/or vein of the retina, and increased intraocular pressure.[2],[12]

Literature review

After searching for pertinent articles on PubMed, a brief literature review with an ending date of November 14, 2020, the Medical Subject Heading terms and Boolean operators (AND OR NOT) were used. Filters for human and observational and analytical studies were applied. No filters were applied for the age of patients.

Articles that included the search terms in the title or abstracts that mentioned possible causes of RBH were selected. Articles that were literature reviews or letters to the editor had insufficient patient data or were written in languages other than English or Spanish were excluded. In addition, data related to the year of publication and type of study, socio-demographic variables such as age and gender, RBH-specific data such as cause and affected eye, and the use or nonuse of anticoagulants or antiplatelets were obtained. The information was recorded on a Microsoft Excel Table® and reported as absolute frequencies, central trends, or dispersion measurements in the case of quantitative variables.

In addition, an anonymous e-mail survey was done at an Ophthalmology Reference Center in Bogota, Colombia, as a primary data source to assess the percentage of RBH cases the doctors had seen during their professional careers.

Clinical case

After a functional surgical procedure, a 79-year-old male patient from San Andres Island, Colombia, who had a history of coronary heart disease and was treated with carvedilol and acetylsalicylic acid (ASA), was followed up. The patient had secondary epiphora due to a failure in the pumping mechanism caused by horizontal laxity in his eyelids associated with pseudoherniation of the inferior orbital fat pads. Therefore, he was scheduled for transcutaneous lower eyelid blepharoplasty and correction of the ectropion. Surgery was done on the lower left eyelid without complications.

During the procedure on the lower right eyelid, significant pain was felt after a skin incision and orbicular dissection with the scalpel. The pain did not go away with the application of an additional dose of 2% xylocaine with epinephrine. Soft monopolar electrocoagulation was done. The physical examination revealed tissue tension and right proptosis while pupil reflex and ocular motility enjoyed unrestricted movement. Lateral canthotomy was carried out: A 1 cm lateral skin incision was made protracted laterally and caudally 7–8 mm. Monopolar electrocoagulation was done. Lateral canthal tendon insertion was identified in Whitnall's tubercle. It was sharply dissected, and the inferior lateral canthal tendon was cut. Surgical wounds were left open but gently held together with Steri-Strips®. The pain disappeared after the procedure, and pupillary reflex and ocular motility were not compromised [Figure 1].

A postoperative follow-up was done, and the patient was found to have 20/20 visual acuity without correction in both eyes. Surgery was done again to close the wound 8 days later.

Literature review

A total of 335 articles were found [Appendix 1], and 43 met the inclusion criteria. As for study design, there are 38 case reports, four case series, and one cohort study. The total population included 118 patients and 118 eyes; 91.5% were unilaterally compromised. The male sex was the most prevalent with 70%, and the median age was 52 interquartile range (0.012). The most frequently published cause of RBH was blunt eye trauma with 11 articles (26%), followed by retrobulbar anesthesia with nine articles (21%), and blepharoplasty and spontaneous RBH with five articles each (11.6%). However, most patients were in the Kallio et al. cohort. In this study, 55 patients had RBH as a complication of retro or peribulbar anesthesia.[13]



About 18 articles (35%) reported that patients received treatment with anticoagulants or antiaggregates concerning the pharmacological background, for example, Vitamin K inhibitors, low-molecular-weight heparins, tissue plasminogen activators, ASA, and GP IIb-IIa complex inhibitors are described. Two studies stated that heparin and ASA were discontinued 48 h before surgery. In addition, the anticoagulant effect with protamine sulfate was reversed in one of the studies.

Two cases of RBH-associated thrombophilia, in turn, were mentioned as hemophilia A and acquired factor VIII inhibitor.

Survey results

As for the survey results done at a Reference Center In Ophthalmology, a group of 35 ophthalmologists, 25% of them general ophthalmologists and 75% specialists, responded to the questions. Of the total, 34% of the respondents had cases of RBH, and in 33% of these cases, the most frequent etiology was trauma.


  Discussion Top


Most studies corresponded to case reports and case series. Unfortunately, research with large sample sizes is scarce, making it difficult to establish the incidence of RBH.

Data in Colombia coincide with what has been previously described in the literature worldwide regarding sex, age, and laterality.[14] The age of presentation is in adulthood. Unilateral eye compromise was the most common finding. Three of the four cases with bilateral compromise were related to systemic conditions. According to what was found in the literature [Appendix 2], most RBH-related causes are associated with blunt eye trauma with or without orbital fracture and a history of Sub-Tenon, peribulbar, or retrobulbar local anesthesia. Blepharoplasty, cataract surgery, orbital fracture repair, and strabismus surgery have also been associated with RBH.



Concerning the factors associated with RBH outcomes, in a systematic review of the literature done by Christie et al. that included a logistic regression analysis, the authors found that the risk factors for a worse RBH visual prognosis were advanced age, trauma, ophthalmoplegia, and pupil defect. However, when a young adult had RBH due to a surgical complication, the presence of proptosis and a marked decrease in visual acuity had better visual outcomes. The Last two variables are associated with a better visual prognosis, because they are severe symptoms that require immediate intervention.[15]

In the older adult population, the pathological backgrounds, such as coagulopathies in young patients and the use of antiplatelet and/or anticoagulants, including ASA and heparins, must be documented. The patient, in our case, was given a preanesthetic evaluation, but the physician did not consider suspending the antiaggregant therapy. Based on this, the ophthalmologist should factor in the pathological and pharmacological history and work with anesthesiologists to determine the risk–benefit of surgery, whether or not to continue anticoagulation and/or antiaggregation therapy and evaluate when to discontinue the medication. This also highlights the importance of close postoperative follow-up on patients with the history mentioned above, as RBH may occur up to 7 days after the surgical procedure.[16],[17],[18],[19] Considering the evidence and experience available, we believe that managing anticoagulation treatment before surgery could potentially decrease the risk of an RBH.

Diagnostic imaging is a valuable tool but is not recommended. RBH is a sight-threatening condition that can have devastating outcomes if not treated immediately.

Canthotomy and cantholysis [Figure 2] are effective methods for urgent orbital decompression.[20] In the case of our patient, the clinical manifestations were intraoperative, were quickly identified, and the procedure was done promptly. Fortunately, the visual recovery was 100%. In a retrospective study done by Bailey et al.,[21] the visual outcome in 15 patients with RBH and the time during which their clinical picture developed before surgery was evaluated. There was an improvement in posttreatment visual acuity for 11 of the 15 patients. Although the average time needed to ensure vision recovery is 3 h,[22] Bailey et al., in their series of patients, found that even after 9 h, there may be a gain in visual acuity. However, an inversely proportional relationship is reported between the time when RBH occurs and the time when canthotomy and cantholysis are done.

  Conclusion Top


Based on the results reported in the literature and the findings obtained in the survey, the conclusion can be drawn that ophthalmologists should assess the urgency of performing surgery on patients who cannot suspend their antiplatelet medication, know the presentation of RBH, and be trained to do the treatment as soon as possible to ensure no visual loss.

Learning points

  • RBH is an ophthalmological complication with a potential risk of irreversible blindness
  • The etiology of RBH is diverse. It includes ocular trauma, local anesthesia, and ophthalmological surgeries
  • The ophthalmologist should keep in mind the pathological and pharmacological history and work with anesthesiologists to determine the risk–benefit of the surgery and whether or not to continue with anticoagulation and/or antiaggregation
  • Canthotomy and cantholysis are effective methods for urgent orbital decompression.
