PURPOSE The dynamic contour tonometer is a nonapplanation contact tonometer designed to be largely independent of the structural properties of the cornea. Theoretically, it may measure intraocular pressure most accurately in abnormally thinner corneas. This study compares intraocular pressure measurements by dynamic contour tonometry with Goldman applanation tonometry in eyes with normal cornea...

Not too long ago, the options for treatment of keratoconus were limited to contact lens wear or penetrating keratoplasty. Times have changed, which is reflected in 4 articles in this issue that have some bearing on current investigation and treatment options. One hundred fifty years ago, Dr. John Nottingham provided the first detailed description of keratoconus, with further observations by his...

objective :t o investigate the hematologic indices of mothers in non-immune hydrops fetalis pregnancies and identify the possible causative role of alpha-thalassemia among them. material and methods: from 2005 to 2007, 11386 hydrops fetalis cases in three major obstetric hospitals affiliated to tehran university of medical sciences were recorded. indirect coombs test and hematologic indices of ...

Introduction Urrets-Zavalia syndrome is an uncommon complication of the deep anterior lamellar keratoplasty in keratoconus. The manifestations of this syndrome are an irreversible mydriasis, iris atrophy and secondary glaucoma. Case report Deep anterior lamellar keratoplasty was done for keratoconus with a presumably healed corneal hydrops in a 21-year-old Caucasian man. The graft remained cl...

OBJECTIVE To describe the current investigation and management of non-immune fetal hydrops, with a focus on treatable or recurring etiologies. OUTCOMES To provide better counselling and management in cases of prenatally diagnosed non-immune hydrops. EVIDENCE Published literature was retrieved through searches of PubMed or MEDLINE, CINAHL, and The Cochrane Library in 2011 using key words (no...

Recurrent non-immune fetal hydrops (NIH) has been reported in the literature but it’s a very rare entity. It has been postulated to be related to a recessive gene. We report a case of recurrent non immune fetal hydrops in a multigravida with no medical history of note. She presented in her current pregnancy with a significant history of having 2(out of 3) previous pregnancies affected by hydrop...

The classical guinea pig model for Meniere's disease, in which endolymphatic hydrops was achieved by destruction of the endolymphatic sac and obliteration of the endolymphatic duct, is a non-physiological profound model with shortcomings in relation to Meniere's disease as seen in patients. We developed a more subtle animal model; the two-phase endolymphatic hydrops. This model is based on a co...
