PURPOSE: To determine the cut-off points of minimum linear diameter (MLD) and base diameter (BD) at which the progression rate of idiopathic full-thickness macular holes (MHs) decreases before vitrectomy. STUDY DESIGN: A retrospective study. METHODS: We investigated the differences in MLD and BD between baseline and operation days in patients with stages 2, 3, and 4 MHs using optical coherence tomography (OCT). Each difference in OCT parameters was divided by the time interval to calculate the MH progression rates and the cut-off points of MLD and BD...

PURPOSE: To compare the safety and efficacy of two different application methods of mitomycin C (MMC)-soaked sponge in trabeculectomy. STUDY DESIGN: Retrospective study. METHODS: We included 71 eyes of 71 patients that had undergone trabeculectomy. In the anterior scleral application group, 36 eyes were treated using the long side of the MMC-soaked sponge placed parallel to the limbus. The efficacy and safety in these eyes were compared with eyes treated with the posterior scleral application group, consisting of 35 eyes treated with the long side of the MMC-soaked sponge placed perpendicular to the limbus...

PURPOSE: The ocular surface microenvironment changes with aging. However, it remains unclear if cellular senescence influences the ocular surface. We investigated the presence of p16INK4a -expressing senescent cells in healthy human conjunctiva. STUDY DESIGN: Clinical and experimental. METHODS: Healthy conjunctival tissue samples were obtained from middle-aged and elderly subjects. RT-qPCR was performed to assess the expression of senescence markers CDKN2A (p16INK4a ) and CDKN1A (p21CIP1/WAF1 ) and immunostaining was performed to examine the expression of the senescence marker p16INK4a , stem cell markers Ki67 and p63, tight-junction marker ZO-1...

PURPOSE: Removing transparent vitreous tissues, such as a residual vitreous cortex (VC) or proliferative membrane, without damaging the retina is often problematic in vitrectomy. We examined the feasibility of an injectable in situ cross-linking hyaluronan hydrogel (XL-HA) for vitrectomy. STUDY DESIGN: Experiments using ex vivo and in vivo animal models. METHODS: HA-dibenzocyclooctyne and HA-azidoethylamine solutions were mixed to form XL-HA, which then gradually formed a hydrogel...

STUDY DESIGN: Retrospective, interventional case series. METHODS: We retrospectively studied 40 eyes of 38 consecutive patients with treatment-naïve nAMD, assessing best-corrected visual acuity (BCVA), foveal thickness, central choroidal thickness (CCT), total number of injections over 1 year, and intended injection interval at the last visit...

PURPOSE: To develop a method to measure the macular pigment optical density (MPOD) using scanning laser ophthalmoscopic images in young adults and children. STUDY DESIGN: Cross-sectional study. METHODS: Blue light reflectance fundus images of 32 healthy subjects were used. A profile of the linear reflectance changes across the center of the fovea on a grayscale fundus image was generated. The ratio of the macula-to-periphery reflection was designated as the peak value of the MPOD (MPOD[FR] ) based on established fundamentals...
