Purpose: To compare Orbscan II and Pentacam keratometry readings in terms of their agreement with a manual Javal type keratometer Methods: In this retrospective study, records of patients who had refractive surgery were reviewed. We extracted data of 765 eyes which had keratometry with the Javal keratometer; of these, 577 had Orbscan II and 200 eyes had Pentacam acquisitions. Minimum (min-K) an...

PURPOSE To evaluate differences in straylight between eyes implanted with a hydrophilic multifocal IOL (Seelens MF; Hanita Lenses, Hanita, Israel) and a hydrophobic multifocal IOL (SN6AD1; Alcon Laboratories, Inc., Fort Worth, TX). METHODS In a prospective cohort study, routinely obtained straylight measurements (C-Quant; Oculus Optikgeräte, Wetzlar, Germany) 3 months after standard phacoemul...

Considerable achievements having been recently made in modern diagnostics and treatment of keratoconus have not diminished the urgency of the given problem as the traditional views of the pathogenesis of keratoconus do not always allow to struggle effectively with this difficult and continuously progressing disease. The objective of the research was to study the peculiarities of biomechanical p...

In this study, we investigated the effects of Inula Britannica on the production of antibodies against ovalbumin, and the differentiation of T cells, in C57BL/6 mice. The oral administration of Inula Britannica suppressed IL-4 and IL-6 production in lymphocytes collected from an inguinal lymph node in the immunized leg. On the other hand, the intraperitoneal administration of Inula Britannica s...

ists with miles of beaches, sea breezes, an arts and museum district, waterfront restaurants, shopping and more. It is also home to a major seaport, Texas A&M University–Corpus Christi, a large health care system, military bases, refineries and chemical plants. Port activity and tourism remain important components of the Corpus Christi economy. However, some sectors are declining in importance,...

Alcoholic extract of root of Inula racemosa, was studied for its antiallergic effect in experimental models of type I hypersensitivity, viz. egg albumin induced passive cutaneous anaphylaxis (PCA) and mast cell degranulation in albino rats. The alcoholic extract was prepared by the process of continuous heat extraction. LD50 of this extract was found to be 2100 +/- 60 mg/kg, i.p. Assessment of ...

PURPOSE To compare a digital infrared pupillometer with a handheld light amplification pupillometer for measuring scotopic pupil size and to evaluate if the postoperative refractive changes of the cornea can influence pupil measurements. DESIGN Prospective noncomparative interventional case series. PARTICIPANTS One hundred eyes, 50 myopic (mean spherical equivalent [SE] refraction [+/- stan...

Distances in virtual environments (VEs) viewed on a head-mounted display (HMD) are typically underperceived relative to the intended distance. This paper presents an experiment comparing perceived egocentric distance real environment with that matched VE presented Oculus Quest and 2. Participants made verbal judgments blind walking object ground. Both 2 produced underperception. Verbal were 82%...
