We read with great interest the article by Aghazadeh Amiri et al. concerning the corneal thickness (CT) measurements with Scheimpflug and slit scanning imaging techniques in keratoconus (KC). We would like to congratulate with the authors for their very interesting paper because it is well known that the measurement of CT is involved in the reliability of intraocular pressure measurements, both...

PURPOSE The authors have previously shown a marked increase in corneal epithelial arachidonic acid metabolism to 12-hydroxyeicosatetraenoic acid (12-HETE) and 12-hydroxyeicosatrienoic acid (12-HETrE) in a model of closed eye-contact lens wear. Their formation was predominantly cytochrome P450-dependent and significantly correlated with inflammatory score and corneal thickness. In the current st...

OBJECTIVES To determine if low doses of topical latrunculin B (LAT-B) will increase outflow facility and decrease intraocular pressure without damaging the cornea and if they will inhibit miotic and accommodative responses to pilocarpine in monkeys. METHODS We measured intraocular pressure (Goldmann tonometry) before and after 1 and 9 doses of 0.005% and 0.01% topical LAT-B and vehicle given ...

PURPOSE To determine if low doses of topical latrunculin B (LAT-B) will increase outflow facility and decrease intraocular pressure (IOP) without adversely affecting the cornea, and inhibit miotic and accommodative responses to pilocarpine, in ocular normotensive monkeys. METHODS Intraocular pressure was measured by Goldmann tonometry before and after one and nine dose(s) of 0.005% and 0.01% ...

OBJECTIVES To assess the repeatability and reproducibility of anterior segment measurements including aberrometric measurements provided by a dual Scheimpflug analyzer (Galilei) system in normal eyes. MATERIALS AND METHODS Three repeated consecutive measurements were taken by two independent examiners. The following were evaluated: total corneal power and posterior corneal power, corneal high...

An experimental setup is designed to detect composite delamination damage based on ultrasonic infrared thermography. The ultrasonic infrared thermography system is composed by ultrasonic excitation system, infrared thermal imager and data acquisition system and two damaged composite plate specimens are produced in the experiment. The image processing methods including thresholding, filters, edg...

PURPOSE To identify relationships between central corneal thickness (CCT) and optic disc topography, as determined by scanning laser ophthalmoscopy (SLO), for patients seen in a specialist glaucoma service. METHODS 272 eyes of 144 patients with primary open angle glaucoma (POAG; n = 71), normal tension glaucoma (NTG; n = 50), ocular hypertension (OH; n = 48) and those considered to be suspici...

flavonoids, are a large class of polyphenols, with more than 4000 combinations. they have an antioxidant role in plant photosynthesis and in the human body they optimally act as an antioxidant, anti-inflammatory, anticancer and protector of the heart. quercetin is in the flavonol group that is used to fight protection specifically against viruses and cancer cells. in this study, comparison of e...
