研究室紹介
Professor Kyung Ah Park's research lab specializes in anterior segment and posterior segment imaging, with a focus on optical coherence tomography (OCT) applications in pediatric and adult ocular diseases. The lab investigates retinal and choroidal layer thickness profiles in various conditions, including preterm development, optic neuritis, and myopic optic disc tilt, leveraging advanced imaging techniques like spectral-domain and enhanced depth imaging OCT. A key direction involves applying deep learning to automate the detection of ocular pathologies from fundus photographs, particularly for myopic tilted discs. The lab also explores long-term complications of intraocular lens implantation, especially in pseudoexfoliation syndrome.

15PURPOSE: To compare retinal layer thickness and choroidal thickness profiles in preterm and full-term children using spectral-domain optical coherence tomography (SD-OCT). METHODS: We performed horizontal and vertical SD-OCT crosshair scans through the fovea with and without an enhanced depth technique in 31 premature and 30 full-term children. Retinal layer and choroidal thicknesses were measured at various locations including the fovea and 1.0 and 3.0 mm nasal, temporal, superior, and inferior
The data, obtained using enhanced depth imaging optical coherence tomography, provide the choroidal thickness profile of healthy children. The characteristic choroidal thickness profile in children suggests a redistribution process of choroidal tissue with aging.
PURPOSE: To compare the retinal layer thickness of eyes with optic neuritis (ON) and that of control eyes and ON eyes with and without neuromyelitis optica (NMO) or multiple sclerosis (MS). METHODS: Horizontal and vertical SD-OCT scans of the fovea were undertaken for 56 patients with ON with and without NMO or MS and for 24 healthy controls. Patients with ON were divided into three groups: NMO, MS and isolated ON without NMO or MS. The thickness of each retinal layer was compared between ON and
DALK is considered a good primary surgical option in patients with recurrent Avellino dystrophy after PTK.
We report 4 cases of pseudoexfoliation syndrome in which pseudoexfoliative material appeared on the intraocular lens (IOL) surface and glaucoma developed more than 8 years after cataract surgery. The IOL haptic was located in the ciliary sulcus in 3 eyes and in the capsular bag in 1 eye. This report suggests that careful follow-up is essential to monitor the development of glaucoma in patients with pseudoexfoliation syndrome, particularly when an IOL is implanted in the sulcus.
BACKGROUND: It is necessary to consider myopic optic disc tilt as it seriously impacts normal ocular parameters. However, ophthalmologic measurements are within inter-observer variability and time-consuming to get. This study aimed to develop and evaluate deep learning models that automatically recognize a myopic tilted optic disc in fundus photography. METHODS: This study used 937 fundus photographs of patients with normal or myopic tilted disc, collected from Samsung Medical Center between Apr
We evaluated changes in parafoveal and peripapillary vessel density in chiasmal compression after decompression surgery using optical coherence tomography angiography (OCT-A). Sixty-two eyes with chiasmal compression for which preoperative and postoperative (4-6 months) OCT, OCT-A, visual field (VF), and comprehensive ophthalmic data were available, and 44 healthy eyes were evaluated. Vessel densities of the superficial retinal capillary plexus (SRCP), deep retinal capillary plexus (DRCP), and r
