Penetrating ocular trauma is one of the most important causes of vision loss, especially in men, and can be associated with intraocular foreign bodies. The incidence of intraocular cilia after trauma is very low. Here we report the case of a 24-year-old man who visited Poostchi Ophthalmology Clinic (Shiraz, Iran) due to a gradual vision loss in his left eye over the past 2 months. The probable ...

Pressure driven liquid flow through rectangular cross-section microchannels is investigated experimentally. Polydimethylsiloxane microchannels are fabricated using soft lithography. Pressure drop data are used to characterize the friction factor over a range of aspect ratios from 0.13 to 0.76 and Reynolds number from 1 to 35 with distilled water as working fluid. Results are compared with the g...

BACKGROUND Lens dislocation is a common disease in ophthalmology, which leads to vision loss, while the lens dislocation caused by vomiting has not been reported yet. We report a case of lens dislocation caused by simple vomiting. This case further implicated for the pathogenesis of lens dislocation. CASE PRESENTATION A 51-year-old male who complained about "dizziness, vomiting, and the visio...

The results are presented in Table I. In three cases of typical Raynaud's disease, one of less than one year's duration, and the others of less than extreme decrease in digital blood flow to approximately four per cent of the normal, with a correspondingly extreme increase in digital vascular resistance to the height of 1740 units (normal 63 to 96 units). The digital arterial blood presure was ...

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 evaluate the influence of anatomical and biomechanical properties of the grafts on the iop measurements methods : in this cross-sectional study conducted on 45 kera...

Paciente com háptica da lente intraocular de peça única, na câmara anterior, tocando o seio camerular pressão 40mmHg. O implante única anterior não é recomendado,() devido a complicações que podem causar, como aumento intraocular, fechamento do ângulo camerular, dispersão pigmento, hemorragia, problemas refração, entre outros. Na literatura, descrevemos alternativa três peças no sulco ciliar ap...

purpose : to compare visual outcome of aspheric and spheric intraocular lenses (iols) implantation in patients with age-related cataract in terms of visual acuity (va), contrast sensitivity (cs) and spherical aberration methods : in this prospective randomized interventional study, 59 consecutive cases of senile cataract who had been admitted for cataract surgery to farabi eye hospital, tehran,...

purpose: to evaluate the effect of trans-scleral cyclophotocoagulation (tscpc) in reducing intraocular pressure in eyes with history of pars plana vitrectomy with or without intraocular silicone oil and refractory to medical treatment. methods: medical records of 35 eyes of 35 patients who underwent tscpc for medically uncontrolled glaucoma after pars plana vitrectomy for retinal pathology were...
