OBJECTIVE

To describe the clinical presentation, management and outcome of a rare case of isolated oculomotor nerve palsy in an immunocompromised adult secondary to a central nervous system (CNS) tuberculoma.

This is a case report.

A Filipino male in his 30s developed severe throbbing headache followed by binocular diplopia and drooping of the right upper eyelid. Findings were compatible with a neurologically-isolated pupil-involving, complete oculomotor nerve palsy on the right. Brain magnetic resonance imaging demonstrated enlargement and contrast enhancement of the cisternal portion of the right oculomotor nerve. Serologic testing was positive for the human immunodeficiency virus (HIV) and syphilis. Cerebrospinal fluid (CSF) analysis showed lymphocytic pleocytosis and elevated protein. CSF polymerase chain reaction was positive for Mycobacterium tuberculosis (TB). The patient was treated with penicillin, quadruple anti-Koch’s, and anti-retrovirals. Eyelid position and ocular motility improved after treatment. Aberrant regeneration of the right oculomotor nerve was observed with elevation of the right eyelid on downgaze (pseudo-Graefe sign).

CNS tuberculoma may present as a neurologically-isolated oculomotor nerve palsy, particularly in immunocompromised individuals. In TB-endemic countries, like the Philippines, it should be considered in the differential diagnosis. Early recognition and appropriate antimicrobial therapy can lead to neurologic improvement.

OBJECTIVE

This study described the ophthalmic symptoms and signs in patients with nasopharyngeal carcinoma (NPCA).

This was a retrospective, cross-sectional, descriptive study involving patients with histologically-confirmed NPCA seen in two subspecialty eye clinics in a single referral hospital from January 2014 to December 2018. Chart review obtained data on symptoms and ophthalmic findings of patients with NPCA on the first visit. Descriptive statistics was used to analyze the data.

There were 36 patients in the study. There were 27 males (75%) and mean age was 47 years (Range: 13 - 83). Delay to consult was marked, with 28 patients (78%) presenting later than three months; 19 (53%) had invasion to distant sites on presentation. Almost all of the patients (35/36 or 97%) had either diplopia or blurring of vision, with nasal symptoms as the most common extra-ophthalmic accompanying symptom. Multiple cranial nerve palsies, particularly optic nerve plus at least one ocular motor nerve, was a prominent feature. The combination of nasal symptoms with ophthalmoparesis was noted in 24 patients (67%) and was identified as a red flag for NPCA.

Blurred vision and diplopia were the most common ocular complaints of patients with NPCA who were evaluated at the ophthalmology department of a tertiary hospital. Blurred vision is frequently from optic nerve involvement while diplopia is due to ophthalmoparesis secondary to multiple ocular motor cranial nerves involvement. Male patients in their 40s who present with combination of optic neuropathy or ocular motor palsies should be probed for presence of otologic or nasal symptoms as well as neck masses as these are the common presentation of NPCA in the ophthalmology clinics.

A white-eyed blowout fracture is an orbital floor fracture associated with restriction of ocular motility (suggestive of orbital content entrapment) but with minimal or absence of signs of soft tissue trauma. It can lead to significant patient morbidity. This case involved an 8-year-old boy with a white-eyed blowout fracture following facial trauma. He presented with binocular diplopia and a history of recurrent episodes of vomiting after the trauma and was referred to our centre for a suspected head injury. Visual acuity in both eyes was 6/9. Examination showed minimal left periorbital haematoma with left eye motility restriction on superior and medial gaze associated with pain. CT scan of the orbit showed left orbital floor fracture with minimal soft tissue entrapment. He underwent urgent open exploration of the left orbit and release of orbital tissue entrapment. Post-operatively, the left eye motility restriction improved significantly with resolution of diplopia. In conclusion, a high index of suspicion is crucial in diagnosing paediatric white-eyed blowout fractures due to lack of external ocular signs.

PURPOSE: To report the clinical manifestations and computed tomography (CT) findings of patients with a trapdoor type medial orbital wall blowout fracture.METHODS: From March 2009 to October 2016, the clinical records and computed tomography findings of patients who underwent surgical treatment for a trapdoor type medial orbital wall blowout fracture were retrospectively analyzed.RESULTS: A total of eight patients (six males and two females) were enrolled with a combined mean age of 14.4 years. Clinical manifestations were eyeball movement limitation (abduction and adduction) and ocular motility pain (eight patients, 100%), diplopia (seven patients, 87.5%), and nausea and vomiting (four patients, 50%). On CT, the distance from the orbital apex to the fracture site was an average of 22.0 mm and occurred in the middle position of the entire wall. Two patients had missed rectus completely dislocated into the ethmoid sinus through the fracture gap and six patients had definite involvement in the fracture gap and edema of the medial rectus muscle. The medial rectus muscle cross-sectional area was 47.7 mm² which was edematous compared to the contralateral eye (40.1 mm²). Orbital wall reconstruction was performed an average of 4.1 days after the injury. In all patients with oculocardiac reflex-like nausea and vomiting immediately improved after surgery. Six out of eight patients who had eyeball movement limitations (abduction and adduction) preoperatively showed adduction limitation after surgery. The eyeball movement limitation and diplopia disappeared 11.7 days and 46.7 days after surgery, respectively.CONCLUSIONS: Patients with trapdoor type medial wall blowout fracture showed characteristic computed tomographic findings and clinical manifestations such as eyeball movement limitation, ocular motility pain, diplopia, and oculocardiac reflex. An understanding of clinical findings and quick surgical treatment are therefore required. The type of eyeball movement limitation was abduction and adduction limitation preoperatively and adduction limitation postoperatively.

BACKGROUND AND PURPOSE: The most-common initial manifestation of Miller Fisher syndrome (MFS) is diplopia due to acute ophthalmoplegia. However, few studies have focused on ocular motility findings in MFS. This study aimed to determine the pattern of extraocular muscle (EOM) paresis in MFS patients. METHODS: We consecutively recruited MFS patients who presented with ophthalmoplegia between 2010 and 2015. The involved EOMs and the strabismus pattern in the primary position were analyzed. Antecedent infections, other involved cranial nerves, and laboratory findings were also reviewed. We compared the characteristics of the patients according to the severity of ophthalmoplegia between complete ophthalmoplegia (CO) and incomplete ophthalmoplegia (IO). RESULTS: Twenty-five patients (15 males and 10 females) with bilateral ophthalmoplegia were included in the study. The most-involved and last-to-recover EOM was the lateral rectus muscle. CO and IO were observed in 11 and 14 patients, respectively. The patients were aged 59.0±18.4 years (mean±SD) in the CO group and 24.9±7.4 years in the IO group (p<0.01), and comprised 63.6% and 21.4% females, respectively (p=0.049). Elevated cerebrospinal fluid protein was identified in 60.0% of patients with CO and 7.7% of patients with IO (p=0.019) for a mean follow-up time from the initial symptom onset of 3.7 days. CONCLUSIONS: The lateral rectus muscle is the most-involved and last-to-recover EOM in ophthalmoplegia. The CO patients were much older and were more likely to be female and have an elevation of cerebrospinal fluid protein than the IO patients.

The aim of the study is to evaluate the hemodynamic changes and the parenchymal perfusion associated with carotid cavernous fistulas before and after embolization using two-dimensional (2D) parenchymal blood flow analysis. A 15-year-old boy presented with 2-month history of progressive right eye proptosis, chemosis, and diplopia after a motor vehicle accident. Intracranial liquid embolization using Onyx-18 through the inferior petrosal approach was done with balloon protection at the opening of the fistula in the internal carotid artery, resulting in complete occlusion of the fistula. Parenchymal blood flow analysis was done before and immediately after embolization. 2D parametric parenchymal blood flow analysis is newly introduced software that can provide data cannot be conveyed by conventional digital subtraction angiography alone. The software allows for objective assessment of the arterial steal and the parenchymal perfusion both pre, and post-embolization. Pre-embolization assessment may influence the therapeutic decision, while post-embolization assessment can evaluate the treatment efficacy.

A cholesterol granuloma is the most common primary lesion of the petrous apex, and accounts for 40% of the pathologies that arise in this region. The primary treatment for symptomatic lesions is by surgery to decompress and drain or to completely remove the lesion. Here we describe the use of infralabyrinthine approach to access a lesion through the temporal bone and completely remove it with the assistance of a 0-degree endoscope. A 43-year-old man visited our clinic for diplopia. Magnetic resonance imaging revealed a 2.3-cm cholesterol granuloma located in the left petrous apex that caused deviation of the left abducens nerve. The tumor was completely removed using the endoscopic-assisted infralabyrinthine approach; the patient is currently being followed up, and there is no evidence of disease recurrence. This case report describes the successful completion of a petrous apex cholesterol granuloma that preserved the cochlear and vestibular systems.

A 49-year-old male presented with horizontal binocular diplopia without facial pain or skin lesion. Limitation of medial gaze in the left eye was revealed on neurological examination, which is accompanied by peripheral facial nerve palsy ipsilaterally. The diagnosis had been made based on the diffusion restriction lesion of left pontine tegmentum. We may denominate a “seven-and-a-half syndrome” and clinician should maintain a high level of awareness of the various syndromes associated with pontine lesions.

PURPOSE: To report a case of pituitary apoplexy presenting as isolated bilateral oculomotor nerve palsy. CASE SUMMARY: A 46-year-old male presented with bilateral ptosis and acute severe headaches for 6 days. He underwent head surgery and bilateral vitrectomy 12 years prior to his visit because of ocular and head trauma. He mentioned that previous visual acuities in both eyes were not good. The initial corrected visual acuity was finger counting in the right eye and 20/500 in the left eye. Ocular motility testing revealed the limitation of adduction, supraduction, and infraduction with complete bilateral ptosis in both eyes, and his left pupil was dilated. He was diagnosed with an isolated bilateral oculomotor nerve palsy. Magnetic resonance imaging indicated pituitary gland hemorrhage with a tumor, which was suspicious of pituitary apoplexy. The patient was treated intravenous with 1.0 g methylprednisolone to prevent the corticotropic deficiency. In addition, he underwent surgical decompression using a navigation-guided transsphenoidal approach and aspiration biopsy. He was confirmed with pituitary adenoma using a pathological examination. The patient's ocular movements began to dramatically improve by the third day postoperatively. At 4 months postoperative follow-up, his ocular movement and double vision were completely recovered. CONCLUSIONS: This was a rare case of pituitary apoplexy with bilateral isolated oculomotor nerve palsy, which was the first report in the Republic of Korea. A full recovery was achieved after early surgical treatment.
