Background: Fine-Needle Aspiration Cytology (FNAC) is used for diagnosis of intraocular, orbital and eyelid lesions. In this study we evaluated the outcome and the accuracy of using this technique in diagnosis of benign or malignant behavior of lesions. Methods: FNAC was performed on 26 specimens obtained from 25 patients with intraocular, orbital and eyelid tumors and the results were compared...

Introduction: This study aimed to investigate the diurnal intraocular pressure fluctuations under dehydration conditions and the relationship between the intraocular pressure fluctuations and blood pressure. Methods: The intraocular pressures (IOP), body weights, as well as systolic and diastolic blood pressures (SBP, DBP) of 36 fasting healthy volunteers were recorded at 8:00 a.m. and 5:00 p.m...

Shadow-mask-assisted flattening and deposition method fabricates wearable intraocular pressure sensors on flexible hydrogel surfaces.

PURPOSE To correlate the ibopamine provocative test with the diurnal tension curve (highest intraocular pressure-IOP and range) in glaucoma. METHODS This is a prospective case series including glaucoma patients from the Federal University of Goiás, Glaucoma Service. Two 2% ibopamine eyedrops were instilled into one or both eyes of each patient, 5 minutes apart. Intraocular pressure was checke...

INTRODUCTION Spontaneous dislocation of intraocular lens with bag is rare. METHODS We report a case of a 56-year-old male who presented with spontaneous anterior dislocation of an in-the-bag intraocular lens 3 years after manual small incision cataract surgery. He had undergone manual small incision cataract surgery with foldable acrylic intraocular lens implantation, and 18 months after cata...

AIMS To determine intraocular and plasma levels of cellular fibronectin (cFN) in patients with uveitis or diabetes mellitus (DM) and to assess the association with disease activity, macular oedema, and vascular leakage on fluorescein angiography. In addition, to examine whether cFN is locally produced in the eye. METHODS Intraocular and plasma levels of cFN were determined by ELISA in 39 pati...

While the relationship between intraocular pressure and plasma osmolarity has been investigated during hemodialysis, no research has been published concerning the relationship between intraocular pressure and plasma colloid osmotic pressure during hemodialysis. We describe a patient with neovascular glaucoma who demonstrated a marked decrease in intraocular pressure during hemodialysis. The pat...
