SC-CPC effectively lowered eye pressure and medication use in Korean patients with uncontrolled glaucoma, showing promise as a useful treatment option despite some visual decline.

In end-stage glaucoma, central 10-degree visual fields with a size V stimulus provide more detectable points and sensitivity than size III, offering better clinical information for managing severe vision loss.

Inconsistent OCT scan placement can skew glaucoma progression analysis, particularly with "R1" registration, potentially leading to misdiagnosis of disease worsening.

OCT reproducibility of RNFL and GCIPL in myopic eyes is excellent, except for temporal quadrant RNFL, which is crucial for glaucoma monitoring.

Kang Dong Hyun, Hwang Young Hoon

Baseline OCT test selection significantly impacts glaucoma progression detection, especially for RNFL. GCIPL progression detection was less affected, highlighting baseline choice as a critical factor.

This study found no significant long-term difference in refractive outcomes between phacotrabeculectomy and phacoemulsification in open-angle glaucoma patients, implying similar refractive predictability for both surgeries.

OCT's Bruch membrane opening detection was inconsistent in 7% of eyes, particularly myopic ones with peripapillary atrophy, impacting glaucoma assessment accuracy.

A novel Finetube MT shunt effectively lowered IOP in refractory glaucoma patients, showing high success rates and minimal hypotony or tube complications, offering a promising treatment option.

Ahn Byung Heon, Hwang Young Hoon, Han Jong Chul

A novel MicroMT device safely and effectively lowered IOP in glaucoma patients for 3 years, offering adjustable drainage and preventing hypotony, making it a promising surgical alternative.

Ko Sung Ju, Hwang Young Hoon, Ahn Sang Il, Kim Hwang Ki

Studying additional Ahmed valve implantation for refractory glaucoma, researchers found it effectively lowered IOP and medication use, offering a viable surgical option when initial AGV fails.

Cirrus HD-OCT retinal tracking improved RNFL measurement repeatability during *some* eye movements in healthy eyes, but not in elderly glaucoma patients or those with nystagmus, limiting its broad clinical utility.

Hwang Young Hoon, Kim Min Kyung, Kim Dai Woo

This study found ~10% of OCT macular GCIPL scans had segmentation errors, particularly in myopic eyes. These errors were often non-reproducible, highlighting the need for careful interpretation in clinical practice.

Hwang Young Hoon, Kim Yong Yeon

This study found the ISNT rule has limited clinical value for glaucoma diagnosis using Cirrus HD-OCT, as it's rarely intact in healthy or glaucomatous eyes.

Hwang Young Hoon, Ahn Sang Il, Ko Sung Ju

Macular ganglion cell asymmetry analysis shows good diagnostic ability for early-stage glaucoma but limited usefulness in pre-perimetric or advanced stages, suggesting its specific role in glaucoma assessment.

Eyes with optic disc situs inversus show distinct retinal nerve fiber layer thickness patterns and smaller cup-to-disc ratios. This is crucial for accurate glaucoma assessment in these patients.

Hwang Young Hoon, Kim Yong Yeon, Kim Hwang Ki, Sohn Yong Ho

This study characterized inner retinal cleavage, finding it's associated with high myopia or ERMs, and structurally distinct from glaucomatous defects, aiding accurate diagnosis.

This study compared OCT maps to photographic RNFL defects in early glaucoma. The thickness map was superior, detecting all photographic defects, indicating its utility for early glaucoma diagnosis.

Cirrus HD-OCT neuroretinal rim measurements in myopic eyes frequently have errors (17.6%), particularly with high myopia, parapapillary atrophy, and vitreous opacities. Clinicians must consider these factors when interpreting results.

Hwang Young Hoon, Kim Hwang Ki, Sohn Yong Ho

This Korean study found average central corneal thickness (CCT) was 530.9 μm, varying with IOP, age, sex, and hypertension. This helps refine glaucoma risk assessment in this population.

Hwang Young Hoon, Yoo Chungkwon, Kim Yong Yeon

Myopic optic disc tilt and rotation alter RNFL thickness patterns, specifically thickening the temporal RNFL. This finding is crucial for accurate glaucoma diagnosis using OCT in myopic patients.

Hwang Young Hoon, Yoo Chungkwon, Kim Yong Yeon

This study found myopic optic disc tilt correlates with altered peripapillary RNFL thickness, especially temporally. Clinically, disc tilt must be considered when interpreting RNFL OCT results.

Hwang Young Hoon, Kim Yong Yeon

Cirrus HD-OCT rim assessment, especially nasal/temporal, improved glaucoma diagnosis over RNFL thickness alone, suggesting different OCT parameters are useful at varying disease stages.
