purpose: to evaluate the diagnosis of intraocular tuberculosis (tb) with polymerase chain reaction (pcr) and to report 13 cases of presumed intraocular tb. methods: of 168 patients with uveitis, 13 patients (7.74%) had criteria for intraocular tb (tb group). thirteen patients with non-tb uveitis were randomly selected as the control group. samples for pcr were obtained from the aqueous humor. s...

PURPOSE To evaluate and correlate the peaks and the fluctuation of intraocular pressure seen in the association of the ambulatory intraocular pressure curve with the water-drinking test versus the peaks and the fluctuation seen in the daily intraocular pressure curve. METHODS The sample was as follows: 77 eyes belonging to 77 patients who were divided into three groups composed of 31 eyes bel...

Abstract Retinoblastoma, the most common intraocular tumor of childhood, was recently shown to comprise two major molecular subtypes. Subtype 1 includes heritable forms, with germline mutation RB1 and a cone-differentiated state. 2 is often non-hereditary, exhibits stemness features, increased expression MYCN its target genes, high risk metastasis. Relative subtype 1, tumors have worse prognosi...

purpose: to compare intraocular pressure (iop) readings measured by the ocular response analyzer (ora) with those measured by the goldmann applanation tonometer (gat) in keratoconic eyes following penetrating keratoplasty (pkp) and to evaluate the influence of anatomical and biomechanical properties of the grafts on iop measurements. methods: this cross-sectional study was conducted on 45 kerat...

purpose: to compare aspheric and spherical hydrophilic intraocular lenses (iols) in terms of contrast sensitivity and visual acuity in photopic and mesopic conditions. methods: this triple-blind randomized clinical trial was performed on 40 eyes of 40 patients at al-zahra eye center, zahedan, iran. the eyes were randomized to standard phacoemulsification procedure with spherical (adapt, b&l;) o...

purpose: to study the pattern of perfusion of central retinal artery (cra) after 0.1 ml intravitreal injection of bevacizumab to verify the need for any maneuver to decrease the intraocular pressure (iop) including anterior chamber paracentesis (acp) methods: this is a prospective, interventional, noncomparative case series. patients receiving intravitreal injection of bevacizumab for choroidal...

purpose: to evaluate the effect of phacoemulsification and posterior chamber intraocular lens (pciol) implantation on intraocular pressure (iop) in eyes with chronic angle-closure glaucoma. methods: twenty-two patients with chronic angle-closure glaucoma (cacg) and visually significant cataract were included in our study. all were underwent phacoemulsification and pciol implantation. iop, depth...

the aim of this study was to report a new cause of cataract, namely snake bite induced cataract in a dog. a 3-year-old male mongrel dog was referred to our clinic for the assessment of cataract in both eyes. the dog was bitten by a snake nearly 4 months ago. a 40 dioptre acrylic lens with 13 mm haptics was implanted into the lens capsule. in the left eye, posterior synechia was detected in the ...

purpose: to evaluate the effects of diurnal fasting during ramadan on intraocular pressure (iop) in healthy subjects. methods: the study was conducted on healthy male volunteer less than 40 years of age without ocular or systemic diseases who were on religious fasting during ramadan, 2004. intraocular pressure were measured at 9 am and 1, 5, and 7 pm in 2nd and 4th weeks of ramadan and also one...

to assess the one year results of artiflex phakic intraocular lens (iol) implantation in the treatment of high myopia. in this non-random interventional study, myopic patients with spherical equivalent worse than -5.0 diopters (d) who were not eligible for laser surgery were assessed. all patients had refraction, uncorrected and best corrected visual acuity tests (ucva and bcva), endothelial ce...
