PURPOSE: To analyse the short-term interaction between a short period of myopic and hyperopic defocus and the muscarinic antagonist homatropine upon the choroidal thickness and ocular biometrics of healthy subjects. METHODS: Thirty young adults (15 myopes and 15 emmetropes) aged 18-35 years had subfoveal choroidal thickness (ChT) and ocular biometry measurements taken before, 30 min, and 60 min following the introduction of monocular optical blur (0.00 D, +3...

Two genes encode the Na+ -K+ -2Cl- cotransporters, NKCC1 and NKCC2, that mediate the tightly coupled movement of 1Na+ , 1K+ , and 2Cl- across the plasma membrane of cells. Na+ -K+ -2Cl- cotransport is driven by the chemical gradient of the three ionic species across the membrane, two of them maintained by the action of the Na+ /K+ pump. In many cells, NKCC1 accumulates Cl- above its electrochemical potential equilibrium, thereby facilitating Cl- channel-mediated membrane depolarization. In smooth muscle cells, this depolarization facilitates the opening of voltage-sensitive Ca2+ channels, leading to Ca2+ influx, and cell contraction...

A 66-year-old Japanese woman who was diagnosed with synovitis-acne-pustulosis-hyperostosis-osteitis (SAPHO) syndrome presented with bilateral blurred vision 4 months prior to visiting our hospital. She had visited a local ophthalmology clinic first. She was diagnosed with conjunctivitis and was prescribed antibacterial eye drops. The symptoms persisted in spite of treatment. She was then referred to our hospital. At her initial visit, the visual acuities were 0.6 in both eyes. A slit-lamp examination revealed bilateral shallow anterior chamber, and intraocular pressures of 18 mm Hg in the right eye and 16 mm Hg in the left eye...

We explored the protective effects of N -acetylcysteine (NAC) on chorioretinal damage induced by photodynamic therapy (PDT) in an experimental rat model of choroidal neovascularization (CNV). METHODS: Experimental CNV was induced by an argon laser in 24 Brown Norway rats 7 days prior to PDT. Commencing 1 day after CNV induction, 0.5 mL of NAC was orally administered daily to the NAC+ group (12 rats), and 0.5 mL of normal saline to the NAC- group (12 rats). Diode laser treatment was delivered for 42 s (total energy, 25 J/cm2) to the left eye prior to verteporfin infusion (PDT-) and to the right eye 15-20 min after such infusion (PDT+)...

Purpose: To investigate early retinal structural and microvascular changes in patients with type 2 diabetes mellitus (DM) and to analyze relationships among the retinal structure, microvasculature, and choroid. Methods: Seventy-seven patients with type 2 DM (40 with no diabetic retinopathy [DR], 37 with nonproliferative diabetic retinopathy [NPDR]), and 34 control subjects were enrolled. Spectral-domain optical coherence tomography, operating in radial 18-line mode, obtained macular images of the eight intraretinal layers and the choroid...
