    Abstract:
    CASE DESCRIPTION: We present a case of a 65-year-old patient who underwent heart transplantation. After the surgery, left proptosis, conjunctival chemosis, and ipsilateral palpebral ecchymosis were found while he was still intubated. A retrobulbar hematoma was suspected, confirmed by a computed tomography scan. Initially, expectant management was considered, but with the appearance of an afferent pupillary defect, the patient underwent orbital decompression and posterior collection drainage, which prevented visual impairment. CONCLUSION AND IMPORTANCE: Spontaneous retrobulbar hematoma after heart transplantation is a rare condition that risks vision. We intend to discuss the importance of postoperative ophthalmologic examination after heart transplantation in intubated patients for early diagnosis and rapid treatment. Spontaneous retrobulbar hematoma (SRH) after heart transplantation is an exceptional condition that risks vision. Bleeding in the retrobulbar space provokes an anterior ocular displacement, extending the vessels and the optic nerve, which can generate ischemic neuropathy and, finally, a loss of vision [1]. A retrobulbar hematoma is usually associated with trauma or eye surgery. Though, in non-traumatic cases, the underlying cause is not evident. An adequate ophthalmologic examination is usually not performed in complex surgeries like heart transplantation. However, this simple measure can prevent permanent vision loss. Non-traumatic risk factors should also be considered, which include vascular malformations, bleeding disorders, use of anticoagulants, and increased central venous pressure usually triggered by a Valsalva maneuver [2]. The clinical presentation of SRH consists of ocular pain, decreased visual acuity, conjunctival chemosis, proptosis, abnormal extraocular movements, and elevated intraocular pressure (IOP). Its diagnosis is often clinical; however, it can be confirmed with computed tomography or magnetic resonance imaging. Treatment aims to reduce IOP with surgical decompression or pharmacologic measures [2]. In the reviewed literature, less than 5 spontaneous ocular hemorrhages related to cardiac surgery have been reported [3-6], of which only one is related to heart transplantation [3]. A clinical challenge of an SRH after heart transplantation is presented below. Surgical management was performed with a favorable result.
