This study found glaucomatous eyes with optic disc hemorrhage have higher stress at the lamina cribrosa-sclera interface, particularly during eye movement. This suggests biomechanical stress contributes to ODH, with age and axial length as risk factors.

This study found laser iridotomy sustained angle widening in two-thirds of patients. Persistent angle closure, seen in 33%, was predicted by a thicker iris and younger age, guiding personalized treatment.

This study found a significant association between periodontitis and open-angle glaucoma, particularly in older adults, men, and diabetics, suggesting a potential systemic link relevant to patient risk assessment.

High myopia causes increased, asymmetric lamina cribrosa stress during eye movement, correlating with glaucoma progression. This highlights biomechanics' role in myopic glaucoma and suggests a new prognostic indicator.

Kang Edward, Park Ji-Hye, Yoo Chungkwon, Kim Yong Yeon

This study found glaucoma progressors exhibit higher asymmetric stress on the lamina cribrosa during eye movement, a factor potentially contributing to progression and linked to optic disc geometry.

Kang Edward, Park Ji-Hye, Yoo Chungkwon, Kim Yong Yeon

This study found that lower lamina cribrosa strain, influenced by IOP and ONH shape, correlated with faster retinal nerve fiber layer thinning in glaucoma, highlighting biomechanics' role in progression.

This study found peripapillary vessel density significantly decreased in the affected hemiretina of glaucomatous eyes, highlighting its potential as an early, sensitive biomarker for monitoring glaucoma progression.

Chun Yeoun Sook, Sung Kyung Rim, Park Chan Kee, Kim Hwang Ki, Yoo Chungkwon, Kim Yong Yeon et al.

This study found overall vision-related quality of life was similar between normal tension and primary open-angle glaucoma, but POAG patients experienced significantly worse social functioning and dependency, guiding patient support.

Ji Min Jung, Park Ji-Hye, Yoo Chungkwon, Kim Yong Yeon

This study found red-free photos and OCT en face images highly correlate in detecting progressive glaucoma nerve fiber layer defects, suggesting en face imaging is a valuable alternative for monitoring.

Park Ji-Hye, Yoo Chungkwon, Kim Yong Yeon

This study found OCT en face images best correlate with red-free photos for localized RNFL defect location, while OCT deviation maps often misidentify them. En face imaging may improve glaucoma diagnosis.

This study found that all visual field loss locations similarly impact glaucoma patients' quality of life, emphasizing that preserving the superior field is as crucial as the inferior field for good VRQOL.

This study found peripapillary vessel density is lower in pseudoexfoliation glaucoma than primary open-angle glaucoma of similar severity, suggesting distinct vascular compromise in PXG.

Chun Yeoun Sook, Sung Kyung Rim, Park Chan Kee, Kim Hwang Ki, Yoo Chungkwon, Kim Yong Yeon et al.

This study found that visual acuity, especially in the better eye, is the most influential factor on vision-related quality of life in glaucoma patients, with greater impact in advanced stages. Prioritizing VA preservation is crucial.

Jung Jae Hoon, Park Ji-Hye, Yoo Chungkwon, Kim Yong Yeon

This study found OCT en face images of the superficial retinal layer highly correlate with red-free photos for detecting localized RNFL defects, suggesting OCT can be an alternative for glaucoma monitoring.

Lee Jae Yeun, Kim Joon Mo, Shim Seong Hee, Lee Jin Young, Yoo Chungkwon, Won Yu Sam et al.

This study found impaired renal function (lower eGFR) was independently associated with a higher prevalence of optic disc hemorrhage in a South Korean population, suggesting a systemic link to this glaucoma sign.

This study found multi-use bottles lead to significantly higher glaucoma medication over-consumption than single-use pipettes, highlighting dispenser type's importance for assessing adherence.

Moon Yeji, Sung Kyung Rim, Kim Joon Mo, Shim Seong Hee, Yoo Chungkwon, Park Ji Hye

This study found PXG patients progress differently than POAG patients; higher baseline IOP and more medications predict PXG progression, guiding tailored management.

Lying on one's side significantly narrowed the anterior chamber angle on the upward-facing eye, suggesting posture can alter angle anatomy, relevant for glaucoma patients.

Young Korean OAG patients showed NTG had asymmetric paracentral visual field defects (deeper superiorly), unlike HTG. This suggests IOP level influences young patients' VF defect patterns.

Sung Kyung Rim, Chun Yeoun Sook, Park Chan Kee, Kim Hwang Ki, Yoo Chungkwon, Kim Yong Yeon et al.

This study found Korean glaucoma patients' vision-related quality of life is impacted by visual function, social factors (education), personality, and treatment burden, highlighting the need for holistic patient care.

Yoo Eunjoo, Yoo Chungkwon, Lee Tae-Eun, Kim Yong Yeon

Open-angle glaucoma patients with initial parafoveal scotoma had narrower retinal arterioles than those with peripheral nasal step, especially in normal-tension glaucoma, suggesting vascular mechanisms influence initial visual field defect location.

180-degree suture trabeculotomy effectively lowered IOP in Korean children with primary congenital glaucoma, showing good long-term success rates with minimal complications, making it a viable first-line treatment.
