Binasal hemianopia caused by pneumosinus dilatans of the sphenoid sinuses.

Bitemporal hemianopia is a significant pathological hallmark of a pituitary lesion; however, binasal hemianopia is rarely reported, except for its known association with other ocular diseases rather than with brain lesions. We report a 24-year-old male with binasal hemianopia caused by pneumosinus dilatans of the sphenoid sinuses.

A quantitative analysis method for comitant exotropia using video-oculography with alternate cover.

Background: The purpose of this study was to evaluate the efficacy of a quantitative analysis method for comitant exotropia using video-oculography (VOG) with alternate cover.

Methods: Thirty-four subjects with comitant exotropia were included. Two independent ophthalmologists measured the angle of ocular deviation using the alternate prism cover test (APCT).

Central nervous system (CNS) involvement is a critical prognostic factor for hemophagocytic lymphohistiocytosis.

Background: Hemophagocytic lymphohistiocytosis (HLH) is a rare multisystem disorder that frequently involves the central nervous system (CNS). We compared the clinical characteristics, treatment, and prognosis of patients with HLH according to the degree of CNS involvement.

Methods: The clinical manifestations, initial laboratory data, treatment, and outcomes for 50 patients diagnosed with HLH and treated at Asan Medical Center between January 1995 and August 2011 were retrospectively reviewed and analyzed.

Amblyopia and strabismus by monocular corneal opacity following suspected epidemic keratoconjunctivitis in infancy.

Purpose: To identify the long term clinical course of amblyopia and strabismus that developed secondary to a monocular corneal opacity following suspected epidemic keratoconjunctivitis (EKC) in infancy.

Methods: This was a retrospective study analyzing the medical records of seven patients, treated in our clinic, who were followed for more than five years.

Results: Four patients in our clinic underwent a corneal ulcer treatment following suspected EKC.

Mitral regurgitation due to chordae tendineae rupture in an infant with aortic coarctation.

A 2-month-old male suddenly developed mitral regurgitation aggravation while waiting for surgical repair of aortic coarctation. There were no signs of infection or history of trauma. Emergency surgery was performed, during which rupture of chordae tendineae of the A2 portion of the anterior mitral leaflet was confirmed.

Surgical outcomes of intermittent exotropia as a function of strabismic angle.

Purpose: To analyze postoperative results of intermittent exotropia as a function of the difference in strabismic angles measured immediately and another time prior to the surgery.

Methods: We reviewed the clinical records of intermittent exotropia patients who received surgery and had differences greater than or equal to 10 prism diopters (PD) between the last preoperative measurement of strabismic angle and another previous measurement. After applying various exclusion criteria, 66 patients were entered into our study.
