Relationship of hypertropia and excyclotorsion in superior oblique palsy.

Purpose: To evaluate the correlation between hypertropia and excyclotorsion in acquired superior oblique palsy (SOP).

Methods: Thirty-one patients with acquired unilateral SOP were recruited for this study. The torsional angle of each patient was assessed via one objective method (fundus photography) and two subjective methods (double Maddox rod test and major amblyoscope).

The Comparison of outcomes between lateral rectus muscles re-recession and medial rectus muscles resection in recurrent exotropia.

Purpose: To compare the surgical outcomes between bilateral lateral rectus muscles (BLR) re-recession and bilateral medial rectus muscles (BMR) resection in recurrent exotropia.

Methods: The medical records of patients with recurrent exotropia who underwent surgery for intermittent exotropia during the 6 years from January 2001 to December 2006 and followed up for more than 6 months were reviewed retrospectively.

Results: In group A, BLR recessions was performed at the first surgery and BLR re-recession was performed at the second surgery.

A case of photic retinal injury associated with exposure to plasma arc welding.

Purpose: To report of photic retinopathy induced by plasma arc welding, and the OCT (optical coherence tomography) results of damaged retinal lesions.

Methods: We describe a case report of a 37-year-old male, working in the steel industry, who presented with central scotoma in both eyes.

Results: On his first visit, one day after performing plasma arc welding with protective gear at work, his best corrected vision was 0.
