Introduction: Consumption of morphine, during pregnancy, in addition to inducing defects in the mother’s nervous system function, caused defects or delays in the formation and evolution of embryonic visual system. In the present study, changes in lens development were assessed in embryos exposed to morphine in utero. Methods: Female Wistar rats (250-300 g) were mated with male rats and pregnanc...

in view of the rapid expansion of contact lens amongst the users, new dimensions have been added to the domain of ophthalmology: giant papillay conjunctivitis, a disease caused by different kinds of contact lens, appears weeks or months after they are used, although some patients are struck years later. the predominant symptoms are increased awareness of lenses, ocular itching, blurred vision a...

Introduction: Utilization of computed tomography (CT) scans is increasing annually. This study aimed to reduce the absorbed dose of sensitive organs in the head (eye lenses and thyroid) and to assess changes in resultant images quality in head scans when the radiation dose is decreased. Material and Methods: An anthropomorphic phantom was examined with head protocols in both helical and sectio...

Weak surface reflections from a simple lens can be used to observe interferences between collimated and focusing laser beams. The superimposed beams ͑one resulting from a double reflection within the lens͒ can be made to have similar intensities near the focus of the weaker beam by choosing the lens prescription and the divergence of the incident laser. An advantage to this inexpensive setup is i...

We have tested the feasibility of tear glucose sensing using a daily, disposable contact lens embedded with boronic acid-containing fluorophores as a potential alternative to current invasive glucose-monitoring techniques. Our findings show that our approach may, indeed, be suitable for the continuous monitoring of tear glucose levels in the range 50-500 microM, which track blood glucose levels...

Choosing a camera for use in the dermatology office is difficult, particularly in the case of a digital camera because the market is constantly evolving. This article explains the features that should be taken into account, including camera type, sensor, lens and macro capability, aperture priority mode, screen, viewfinder, operating speed, flash, battery, memory card, and image format. The mos...

this study compared tear function tests and cytologic changes on the conjunctival surface in asymptomatic patients wearing contact lens of different materials. included in this study were 40 eyes wearing daily wear 4 week replacement hydrogel (h) lenses, 32 eyes wearing silicone hydrogel (sih) lenses, 18 eyes wearing rigid gas-permeable (rgp) lenses, and 21 healthy eyes (no lenses) as the contr...

The importance of the large Maf transcription factor family has been investigated in lens development in the chick, Xenopus and mammals. Previously we reported that c-maf-deficient mice exhibit severe defects in lens fibre cells. Here, we report the roles of other large Mafs, MafA/L-Maf and MafB, during mouse lens development. MafA/L-Maf and MafB were expressed in lens epithelial cells and fibr...
