Seasonal variation in acute post-cataract surgery endophthalmitis incidences in South Korea.

Purpose: Previous studies have reported conflicting results on the influence of seasons on post-cataract surgery endophthalmitis incidences. This study aimed to investigate the seasonality associated with the incidence of postoperative endophthalmitis, and to evaluate its association with climate variables in South Korea.

Setting: South Korea.

Comparison of Solar Radiation and Myopia Occurrence in South Korean Children.

Purpose: To investigate the association between regional solar radiation and myopia occurrence in South Korean children.

Materials And Methods: A population-based cross-sectional study using data of 1218 children aged 7-9 years from the Korea National Health and Nutritional Examination Survey was conducted from January 1, 2008, to December 31, 2012. Myopia prevalence and the mean spherical equivalent were estimated; myopia was defined as spherical equivalent refraction <-1.

Endophthalmitis after Cataract Surgery in Korea: A Nationwide Study Evaluating Incidence and Risk Factors in a Korean Population.

Purpose: To assess the nationwide rate of acute postoperative endophthalmitis (APE) after cataract extraction in Korea and to evaluate potential risk factors thereof.

Materials And Methods: Nationwide insurance claims data from July 2014 to June 2017 were reviewed. All patients with phacoemulsification or extracapsular/intracapsular cataract extraction were included.

Refractive change caused silicone oil adhesion to the intraocular lens following Nd:YAG posterior capsulotomy.

A 32-year-old female who had undergone the silicone oil removal procedure presented with visual disturbance in her left eye. Several months previous, she had cataract surgery in a private clinic, and a month later she had a Nd:YAG laser procedure for posterior capsulotomy. The slit-lamp examination revealed silicone oil droplets that had adhered to the intraocular lens where the posterior capsulotomy was performed.

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.

Vertical rectus muscles transposition in large exotropia with medial rectus muscle transection following endoscopic sinus surgery.

Purpose: To evaluate the effect of transposition procedures on the vertical rectus muscle (VRM) in the patients who underwent a medial rectus muscle (MR) transection after endoscopic sinus surgery (ESS).

Methods: In 4 patients with exotropia (XT) and a lack of adduction after ESS, orbital CT or MRI revealed a complete transection of the midportion of the MR. Full-tendon VRM transposition was performed within 3 months after injury (early surgery) in 2 patients with 40 delta XT.

Conjunctival expansion using a subtenon's silicone implant in New Zealand white rabbits.

Purpose: In the field of ophthalmology, the conjunctival autograft is a useful therapeutic material in many cases, but the small size of the autograft is a disadvantage. Therefore, we evaluated the feasibility of taking an expanded sample of conjunctival tissue using a subtenon's silicone implant.

Materials And Methods: We included a total of nine rabbits; eight rabbits were operative cases, and one was a control.

The clinical course of consecutive esotropia after surgical correction.

Purpose: To investigate the clinical course in patients who underwent surgical correction of consecutive esotropia.

Methods: The medical records of 13 patients who underwent surgical correction of consecutive esotropia were reviewed retrospectively. The authors investigated the deviation and surgical method at the time of exotropia surgery.

Calcium mobilization by activation of M(3)/M(5) muscarinic receptors in the human retinoblastoma.

Activation of muscarinic acetylcholine receptors (mAChR) is one of the most important signal transduction pathways in the human body. In this study, we investigated the role of mAChR activation in relation to its subtypes in human retinoblastoma cell-lines (WERI-Rb-1) using Ca(2+) measurement, real-time PCR, and Western Blot techniques. Acetylcholine (ACh) produced prominent [Ca(2+)](i) transients in a repeated manner in WERI-Rb-1 cells.

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.

Valsalva retinopathy associated with fiberoptic gastroenteroscopy.

Case Report: A 45-year-old woman presented with a sudden loss of vision in her left eye, which occurred while she was having a routine upper fiberoptic gastroenteroscopy. According to the gastrointestinal specialist, the patient had performed multiple sustained Valsalva maneuvers during the procedure. Funduscopy showed a preretinal hemorrhage with a half disc diameter in the fovea of the left eye.

Juvenile xanthogranuloma as an isolated corneoscleral limbal mass: a case report.

A case of a juvenile xanthogranuloma of the corneoscleral limbus was encountered in a 5-year-old oriental boy, who presented with a 5-month history of a lump in the right eye. The lesion extended from the inferior limbus. This yellow-orange mass was vascular and firmly fixed to the underlying tissue.

Transcaruncular approach to blowout fractures of the medial orbital wall.

Transcutaneous and transconjunctival approaches are still frequently used to repair orbital wall fractures. However, medial orbital wall fracture remains a challenging area for plastic surgeons due to technical difficulties and postoperative scars. The transcaruncular approach is described and we present our experience with this approach to access the medial orbital wall in 10 patients with blowout fracture in the medial orbital region.

Development of parafoveal exudates and serous retinal detachment in a pregnant woman with tuberous sclerosis.

The authors describe an unusual case of a serous detachment of the fovea and decreased vision with parafoveal exudates with subsequent spontaneous resolution and return of central vision in a pregnant patient with tuberous sclerosis. To our knowledge, this is the first report of an ocular change during gestation in a patient with tuberous sclerosis.
