Introduction: The present study aimed to present a numerical analysis of the penetration depth,  specific absorption rate (SAR), and temperature rise in various eye tissues with varying distance between radiation source and exposed human eye tissues (i.e., cornea, posterior chamber, anterior chamber, lens, sclera, vitreous humor, and iris) at frequencies of 900 and1800 MHz. Materials and Method...

PURPOSE To evaluate the effects of hemodialysis (HD) on corneal and anterior chamber morphometry, as well as intraocular pressure (IOP) in patients with end-stage renal disease. METHODS Fifty right eyes were examined 30 minutes before and after HD. IOP was measured with a Goldmann applanation tonometer, and Ehlers' formula was used to calculate the corrected IOP values. The central corneal th...

When the cornea of the eye dissolves, most commonly secondary to infection or trauma, the ventral wall of the anterior chamber of the eye is no longer supported and thus bulges forward, enlarging the anterior chamber volume. This is referred to as a corneal melt, and it has a unique CT appearance that has not been previously described.

OBJECTIVE It is aimed to determine whether fasting during Ramadan has any significant effect on anterior chamber parameters, visual acuity and intraocular pressures. METHODS 31 fasting (Group 1) and 30 non-fasting healthy volunteers (Group 2) were enrolled. All cases underwent an ophthalmological examination and anterior segment parameter evaluation (central corneal thickness (CCT), anterior ...

OBJECTIVE This study aims to investigate the changes of anterior chamber morphology after laser peripheral iridotomy (LPI) in primary angle-closure (PAC) patients using Pentacam. METHODS 35 normal persons and 35 patients of PAC before and 1 week after neodymium: yttrium: aluminum garnet (Nd: YAG) LPI were evaluated with Pentacam. We measured the anterior chamber angle (ACA), central anterior ...

purpose : to evaluate intraocular pressure (iop) and anterior chamber depth (acd) change after phacoemulsification with posterior chamber intraocular lens implantation methods : in this quasi-experimental study, 84 patients with senile cataract were included. all patients had normal iop. patients with traumatic and complicated cataract, any history of uveitis, glaucoma, or other ocular disease ...

The anterior chamber fluid in cynomolgus monkeys was replaced by a solution of albumin and diodone (iodopyracet) labeled with different isotopes of iodine. After 45 to 120 minutes the chamber fluid was collected and analyzed. The same type of experiment icas performed with albumin and my o glob in and with albumin and gamma globulin. In some of the experiments with albumin and myoglobin, the ti...

OBJECTIVE To compare the changes in anterior chamber volume (ACV), anterior chamber depth (ACD) and anterior chamber angle (ACA) before and 6 months after femtosecond laser in situ keratomileusis (LASIK) for hyperopia using the Pentacam HR device. METHODS A total of 24 eyes of 24 consecutive hyperopic patients undergoing femtosecond LASIK were examined preoperatively and 6 months postoperativ...

AIM To study the effects of gender, eye side and age on anterior chamber measurements; To compare the anterior chamber parameters between glaucoma and normal subjects. METHODS A total of 169 patients (299 eyes), of which 122 normal subjects (218 eyes), 24 cases (39 eyes) with primary angle-closure glaucoma (PACG) and 22 cases (42 eyes) with primary open-angle glaucoma (POAG) visiting our hosp...
