BACKGROUND AND OBJECTIVES: The suppression head impulse (SHIMP) test has emerged as one of the new vestibular function tests. The SHIMP test is an analysis of anti-compensatory saccadic movements in gazing moving targets as the head moves. In this study, we investigated the accuracy and sensitivity of the test. SUBJECTS AND METHOD: We analyzed the results of SHIMP test (gain, amplitude, and latency) in 24 cases, which included normal, vestibular neuritis, benign paroxysmal positional vertigo (BPPV), Meniere's disease, bilateral vestibular function loss, temporal bone fracture, tuberculosis meningitis and acoustic schwannoma patients. We also carried out a physical exam, audiologic study, video electronystagmography (vENG) and a conventional video head impulse test to evaluate the feasibility of SHIMP test in cases of vesitibulopathy. RESULTS: In patients with vestibulopathy, the analysis of SHIMP test indicated high sensitivity and accuracy, which were supported by accompanying audio-vestibular studies. Patients suspected with BPPV, vestibular neuronitis and Meniere's disease showed low vestibulo ocular reflex (VOR) gain and delayed anticompensatory saccade with smaller and more scattered amplitudes than the control. Patients with bilateral vestibular function loss, temporal bone fracture, tuberculosis meningitis, and acoustic schwannoma showed delayed latency, and small amplitude or few anticompensatory saccades. Finally, changes in the SHIMP test values might be a hint that patients had recovered from vestibular neuronitis and tuberculosis meningitis. CONCLUSION: We found the feasibility of SHIMP test in detecting the pathologic condition of VOR in vestibulopathy patients. We argue that the usefulness of SHIMP test might be extended to evaluating the effectiveness of rehabilitation.

OBJECTIVETo investigate optical coherence tomography (OCT) characteristics of tuberculous serpiginous-like choroiditis (Tb-SLC) and serpiginous choroiditis (SC) and to perform OCT to differentiate between these conditions.

METHODSThis retrospective, case-control study examined consecutively enrolled patients with active Tb-SLC or SC. Patients underwent comprehensive ocular examinations and imaging (OCT, color fundus photography, autofluorescence imaging, fluorescein angiography, and indocyanine green angiography). Findings were examined and compared between eyes with SC and Tb-SLC.

RESULTSNine patients with active Tb-SLC (14 eyes) and 8 with active SC (12 eyes) were included. The following OCT findings were observed significantly more often in the Tb-SLC group than in the SC group: vitreal hyper-reflective spots [5 Tb-SLC eyes (36%), no SC eyes; P = 0.02], intraretinal edema [11 Tb-SLC eyes (79%), 3 SC eyes (25%); P = 0.01], sub-retinal pigment epithelium (RPE) drusenoid deposits [11 Tb-SLC eyes (79%), 2 SC eyes (17%); P < 0.01], and choroidal granulomas [8 Tb-SLC eyes (57%), 2 SC eyes (17%); P = 0.03]. A hyporeflective, wedge-shaped band was observed more often in the SC group [5 Tb-SLC eyes (36%), 9 SC eyes (75%); P = 0.045] than in the Tb-SLC group. The incidence of other OCT signs did not differ between the groups and included outer nuclear layer hyper-reflection, outer retinal tabulation, and choriocapillaris point-like hyper-reflection.

CONCLUSIONVitreal hyper-reflective spots, intraretinal fluid, sub-RPE drusenoid deposits, and choroidal granulomas on OCT images may indicate Tb-SLC. Additionally, a hyporeflective, wedge-shaped band may indicate SC. Therefore, OCT is likely helpful in differentiating between Tb-SLC and SC.

PURPOSE: To evaluate the usefulness of the interferon-gamma release assay (IGRA) for diagnosing tuberculosis (TB)-related uveitis (TRU). METHODS: Records from 181 patients with ocular signs and symptoms suggestive of TRU and intraocular inflammation of unknown etiology were reviewed. All subjects underwent clinical and laboratory testing, including IGRA, to rule out presence of underlying disease. A diagnosis of presumed TRU was made based on an internist's TB diagnosis and a patient's response to anti-TB therapy. Sensitivity, specificity, and positive predictive values of IGRA for TRU diagnosis were calculated. Clinical characteristics were compared between patients with positive and negative IGRA results. RESULTS: The sensitivity and specificity of IGRA for TRU were 100% and 72.0%, respectively. Mean age, percentage of patients with retinal vasculitis, and the anatomic type of uveitis were significantly different between patients with positive and negative IGRA results (all p < or = 0.001). Positive IGRA rates and false-positive rates were significantly different between age and anatomic type groups (both p = 0.001). The positive predictive value of the IGRA among patients with intraocular inflammation was high (70%) when all of younger age (< or =40 years), posterior uveitis, and retinal vasculitis were present. CONCLUSIONS: The IGRA is useful for diagnosing TRU in the Korean population, especially when it is used as a screening test. Clinical characteristics, including younger age (< or =40 years), posterior uveitis, and retinal vasculitis in IGRA-positive patients, increase the likelihood of the patient having TRU.

PURPOSE: To report a case of ciliary body tuberculoma, which induced scleral melting. CASE SUMMARY: A 32-year-old man, who was diagnosed with miliary pulmonary tuberculosis 1 week earlier, presented with a conjunctival injection and mass on his right eye 3 months in duration. On excisional biopsy, melted sclera and exposed uveal tissue were found; acid-fast stain was positive. Two months after anti-tuberculosis treatment, anterior granulomatous uveitis and granuloma formation on the anterior chamber angle developed. A low-dose systemic steroid therapy was added. Six weeks after systemic steroid therapy, anterior uveitis and granuloma on anterior chamber angle disappeared. CONCLUSIONS: We experienced a case of ocular tuberculosis on the ciliary body. A low-dose systemic steroid along with multi-drug anti-tubercular therapy may be an effective treatment of ciliary body tuberculoma.

PURPOSE: To report clinical features and optical coherence tomographic findings of presumed atypical ocular tuberculosis associated with tuberculosis lymphadenitis and encephalomeningitis. CASE SUMMARY: A 28-year-old female with lymphadenitis in the axillary area presented with a fever and headache of a one week duration. CSF study and MRI findings implied tuberculosis encephalomeningitis, and presumed tuberculosis uveitis manifested with visual disturbance after five days. Ocular symptoms were aggravated and showed anterior iridocyclitis, vitritis, macular edema, and multifocal retinitis with miliary granuloma that was distinct from choroiditis or typical tuberculosis granuloma. After the patient received anti-tuberculosis medication and systemic corticosteroids, significant improvements in visual acuity, ocular findings and OCT results were observed. CONCLUSIONS: Ocular tuberculosis can present with various clinical findings, and caution should be taken so as not to misdiagnose based on these characteristics. In the present case, anti-tuberculosis medication and systemic steroids resulted in the resolution of inflammation. In such cases, monitoring the posterior pole lesion via OCT may be helpful in determining improvement.

PURPOSE: To analyze ocular manifestations of herpes zoster ophthalmicus and evaluate risk factors and complications affecting visual acuity. METHODS: Ocular, cutaneous, and systemic findings were analyzed retrospectively from the medical records of 81 patients, admitted between 1994 and 2007, to the dermatology department of our hospital for the management of herpes zoster ophthalmicus. RESULTS: Herpes zoster ophthalmicus was manifested as eyelid eruption (93%), conjunctivitis (80%), keratitis (67%), iridocyclitis (36%), secondary glaucoma (20%), or extraocular muscle palsy (1%). Some patients had accompanying systemic illnesses, including malignancy, hepatitis, diabetes mellitus, chronic obstructive pulmonary disease, tuberculosis, and cerebrovascular disease. Patients with decreased vision during the follow-up period were statistically more likely to have presented with keratitis (p=0.032). However, 86% of these patients recovered vision over a 6-month period. CONCLUSIONS: Patients presenting with keratitis upon initial evaluation are at risk for decreased vision and require appropriate ophthalmic evaluation and management.

Tuberculous uveitis is a rare manifestation of tuberculosis infection. Although early diagnosis is important to saving the sight of patients, it is difficult. In dialysis patient, the diagnosis of tuberculosis is often delayed because of non-specific symptoms and extrapulmonary involvements. We report a case involving a 37-year-old man receiving hemodialysis who was presented with persistent fever and left- sided blurred vision. At ophthalmic examination, active papillitis, vitritis, and peripapillary retinal detachment were observed. Neck computed tomography showed multiple necrotic lymphadenopathies (LAPs) in right lateral neck, which was proven as tuberculous lymphadenitis on histological examination. After anti-tuberculosis therapy, fever was subsided and LAPs were improved. Visual acuity was also improved.

PURPOSE: To describe a case of symptomatic rifabutin-related uveitis with hypopyon and vitreous opacity in apatient with acquired immunodeficiency syndrome infected with Mycobacterium tuberculosis. CASE SUMMARY: A 33-year-old male patient with acquired immunodeficiency syndrome was referred to our clinic for abruptly decreased vision in his right eye. Multi-drug therapy with rifabutin was administered for 5 weeks to treat tuberculosis enteritis and pulmonary tuberculosis. Visual acuity of the right eye was hand motion and hypopyon as well as vitreous opacity was found in ocular examinations. Other serologic tests, anterior chamber paracentesis and lumbar puncture test were normal. Rifabutin was immediately stopped and topical steroid and cycloplegics were administered, which resulted in resolution of the hypopyon, vitreous opacity and visual acuity. Four weeks after the initial episode, rifabutin was restarted to treat the pulmonary tuberculosis and rifabutin-related uveitis relapsed in the opposite eye. CONCLUSIONS: Rifabutin-related uveitis should be considered in cases of uveitis in immunosuppressive patients, especially in acquired immunodeficiency syndrome patients. Underlying disease and medication history should be carefully assessed.

We report a rare case of oculomotor nerve palsy and choroidal tuberculous granuloma associated with tuberculous meningoencephalitis. A 15-year-old male visited our hospital for an acute drop of the left eyelid and diplopia. He has been on anti-tuberculous drugs (isoniazid, rifampin) for 1 year for his tuberculous encephalitis. A neurological examination revealed a conscious clear patient with isolated left oculomotor nerve palsy, which manifested as ptosis, and a fundus examination revealed choroidal tuberculoma. Other anti-tuberculous drugs (pyrazinamide, ethambutol) and a steroid (dexamethasone) were added. After 3 months on this medication, ptosis of the left upper eyelid improved and the choroidal tuberculoma decreasedin size, but a right homonymous visual field defect remained. When a patient with tuberculous meningitis presents with abrupt onset oculomotor nerve palsy, rapid re-diagnosis should be undertaken and proper treatment initiated, because the prognosis is critically dependent on the timing of adequate treatment.
