Professor Ki Ho Park's research lab specializes in glaucoma diagnostics and progression monitoring, with a strong focus on retinal imaging and biomarkers. The lab investigates macular ganglion cell-inner plexiform layer (GCIPL) thickness using spectral-domain optical coherence tomography (SD-OCT) to improve early detection and longitudinal monitoring of glaucomatous damage. A key research direction involves evaluating the role of endogenous stress responses, such as the heat shock response, in neuroprotection and potential therapeutic strategies. The lab also explores risk factors for glaucoma in specific populations, particularly in young adults with normal intraocular pressure and high myopia.
Figures are computed from collected data and may differ slightly.
These results demonstrate the possibility of a novel therapeutic approach to glaucoma through an enhanced induction of the endogenous heat shock response.
The macular area is important to the detection of glaucomatous retinal ganglion cell (RGC) damage. Macular thickness complementary to peripapillary retinal nerve fibre layer (RNFL) thickness can well reflect glaucomatous damage, given that the macula contains more than 50% of the RGCs in a multilayered pattern and larger RGC bodies compared with their axons. Thus, macular ganglion cell thickness parameters recently have been considered to be an effective glaucoma-diagnostic tool comparable to RN
The macular GCIPL thickness and deviation maps showed excellent long-term intervisit reproducibility. Macular ganglion cell analysis can be considered as an effective means of monitoring glaucomatous progression in macula.
The inferotemporal macular GCIPL thickness was the best PPG-detection parameter for myopic eyes. Inferotemporal macular GCIPL thickness evaluation can be considered to be a useful means of diagnosing PPG in myopic eyes.
Intraocular pressure (IOP), the pressure within the eyeball, is a function mainly of the production and elimination of aqueous humour. Balanced IOP helps to maintain the eyeball contour, allowing proper refraction of light in the anterior segment of the eye. Increases in IOP can cause injury to the ocular structure, typically the optic nerve head and retinal ganglion cells. IOP increase, additionally, is a risk factor for glaucoma progression. However, it is not unusual that glaucoma worsens des
High myopia, fasting capillary glucose level ≥200 mmol/L and high-density lipoprotein cholesterol level were significant risk factors for open-angle glaucoma with normal baseline intraocular pressure in a young Korean population.
The underlying mechanism of disc hemorrhage is complex like that of glaucoma. The ongoing controversy respecting the role of disc hemorrhage as a risk factor for glaucoma progression notwithstanding, special attention entailing closer follow-up and/or treatment escalation is recommended for patients with disc hemorrhage. Further studies investigating the unrevealed pathogenesis of disc hemorrhage and its prognostic value in glaucoma are warranted.
Although the rates of change were typically slow, more than half of normotensive patients with PPG showed statistically significant progressive structural or functional changes in medically treated cases. DH or IOP reductions of <20% from the baseline were shown as a significant risk factor for the progression of PPG.
Sectoral macular SMD showed topographic correlations with macular GCIPL thickness and circumpapillary RNFL thickness in patients with GS and early-stage NTG. Macular SMD analysis is potentially useful in the clinical evaluation of early glaucoma.
This study shows that average RNFL thickness after PRP undergoes early thickening and subsequent progressive thinning throughout the 2 years post-PRP. This temporal change varies according to the peripapillary RNFL quadrant. Our results also indicate that temporal RNFL and foveal thickness have a similar pattern of long-term change after PRP.
