PURPOSE: We present a computerized method of measuring binocular alignment using a selective wavelength filter and an infrared camera, and validate the efficacy of automated image analysis compared to the gold standard prism and alternate cover test (PCT). METHODS: A prospective observational pilot study was performed on 30 subjects with intermittent exotropia, 30 subjects with esotropia, and 30 orthotropic subjects who were able to cooperate with the PCT. Two independent ophthalmologists examin

OBJECTIVE: To investigate the incidence of ethambutol (EMB) induced optic neuropathy prescribed at a relatively low dose of ≤ 15 mg/kg/day for the treatment of tuberculosis (TB) or Mycobacterium avium complex (MAC) lung disease. DESIGN: Patients diagnosed with TB or MAC lung disease received multidrug regimens including EMB at a single institution from August 2003 to July 2009. Visual monitoring was performed at baseline and at regular follow-up. The incidence of EMB-induced visual disturbances

BACKGROUND/AIMS: To determine whether the development of non-arteritic anterior ischaemic optic neuropathy (NAION) is increased among patients newly diagnosed with obstructive sleep apnoea (OSA) in a large general population. METHODS: A 12-year nationwide, population-based, retrospective cohort study including 1 025 340 beneficiaries in the 2002-2013 Korean National Health Insurance Service database was performed. We identified 919 patients newly diagnosed with OSA aged ≥40 years and matched 919

The 3D Strabismus Photo Analyzer is a simple and reliable tool for measuring ocular deviation. It has excellent agreement with the Krimsky test and substantially improved reproducibility.

BACKGROUND: Besides the devastating complication of blindness, paralysis of the eye muscles, namely ophthalmoplegia, may occur after cosmetic facial filler injection. However, little is known of the clinical characteristics and prognosis of such complications. This study was performed to investigate the natural course of ophthalmoplegia and development of sensory strabismus secondary to blindness after iatrogenic occlusion of the ophthalmic artery and its branches resulting from cosmetic facial

The ratio of paretic/normal side superior oblique muscle area and volume has an excellent predictability in diagnosing trochlear nerve absence in congenital superior oblique palsy.

BACKGROUND: Thymoma is associated with various paraneoplastic autoimmune disorders. Herein, we report paraneoplastic neuromyelitis optica (NMO) associated with both anti-aquaporin-4 (AQP4) immunoglobulin G (IgG) and type 1 antineuronal nuclear antibody (ANNA-1) in an invasive thymoma patient. CASE PRESENTATION: A woman presented with a sudden onset of bilateral progressive visual loss associated with recurrence of invasive thymoma, 6 years after thymectomy and immunosuppressive treatment.
