PURPOSE Our aim was to extend the concept of blink patterns from average interblink interval (IBI) to other aspects of the distribution of IBI. We hypothesized that this more comprehensive approach would better discriminate between normal and dry eye subjects. METHODS Blinks were captured over 10 minutes for ten normal and ten dry eye subjects while viewing a standardized televised documentar...

ABSTRACT
 
 Introduction: Optic disc pit is a rare congenital abnormality of the optic disc. It generally appears in third or fourth decade life; however, cases serous detachment children have been reported. Treatment includes argon laser to peripapillary region, macular buckling surgery, vitrectomy combined with and/or gas injection.
 Objective: To report case maculopathy 13 yea...

purpose: to report the first case of concomitant optic nerve transection and chorioretinitis sclopetaria patient and findings: a 12-year-old boy with history of bb gun injury to his right eye was referred for loss of vision 8 months after the accident. visual acuity in the right eye was counting fingers at one meter with 3+ rapd. on slit lamp examination, right eye seemed normal except 1+ anter...

grave’s disease is a clinical syndrome consisting of hypermetabolism, diffuse thyroid enlargement and exophthalmos. which has ocular complications. due to the high incidence of these complications and the risk of blindness special attention is needed. many therapeutic methods including medical surgical and radiotherapy for ocular complications are suggested. in cases of medical therapy failure,...

the present study introduces a rare case with secondary glaucoma due to anterior chamber lipoma and uveitis in a pekingese dog in iran. a four-year-old castrated male pekingese dog was referred to the private clinic with impaired vision of the left eye, pain, rubbing the left eye onto carpet, presence of a milkycoloured mass into the anterior chamber, and loss of appetite. the clinical examinat...

This research aimed to investigate if age of onset affects the pathogenesis of amblyopia. Amblyopic subjects were compared with normal controls. Strabismic amblyopes were assigned to early or late onset groups on the basis of detailed clinical history. Confirmatory histories were obtained from parents where possible. Contrast Sensitivity (CS) to a 3.2 cyc/deg (cpd) sinusoidal grating pattern wa...

purpose: to determine bacterial flora of the conjunctiva and lacrimal sac in adult patients with naso-lacrimal duct obstruction (nldo) in comparison with normal flora. methods: this study included 40 consecutive adult patients with nldo and 40 age- and sex matched healthy controls. specimens for bacterial culture were obtained from the involved and normal conjunc-tiva preoperatively and from th...

The effects of gold nanoparticles (GNPs) in 125I brachytherapy dose enhancement on choroidal melanoma are examined using the Monte Carlo simulation technique. Usually, Monte Carlo ophthalmic brachytherapy dosimetry is performed in a water phantom. However, here, the compositions of human eye have been considered instead of water. Both human eye and water phantoms have been simulated with MCNP5 ...
