BACKGROUND Posterior keratoconus is a rare cause of a corneal opacity in an infant. It is characterized by thinning of the posterior cornea without ectasia of the anterior cornea. Imaging of this condition with anterior segment optical coherence tomography (AS-OCT) has not been reported in the literature. CASE PRESENTATION A six week old African-American male presented with a congenital corne...

This is a case report of a symptomatic non-clearing, vascularized, disciform, corneal stromal edema with a feeder vessel that has remained refractory to medical therapy of antiviral, steroid, and antibiotics, for a period of three weeks, but showed a rapid improvement in visual acuity of 0.1 Log mar within five days of feeder vessel cauterization, together with improvement of two psychometric s...

A combination of 0.1% tetracaine HCl and 0.4% oxybuprocaine HCl is used when carrying out morphometrical corneal studies in vivo by means of ultrasound pachymetry. The aim of this was to determine the effect of a combination of 0.1% tetracaine HCl and 0.4% oxybuprocaine HCl anesthetic eye drops on central corneal thickness values. We carried out a prospective study involving 30 eyes of 30 healt...

PURPOSE To investigate the changes in dry eye symptoms and clinical signs and corneal sensitivity after small incision lenticule extraction (SMILE) and femtosecond LASIK (femto-LASIK). DESIGN Prospective, non-randomized comparative study. METHODS The study included a total of 71 eyes of 71 patients; the SMILE group comprised 38 eyes of 38 patients, and the femto-LASIK group comprised 33 eye...

rabbits are widely used as laboratory animals for experimental surgery. anesthesia of rabbits may present complications unless the method is easy to apply and safe to use. in present study, effects of different dosages of vitamin c on thiopental sodium induced anesthesia in 25 male new zealand white rabbits were studied. in the animals that had not received vitamin c treatment before thiopental...

PURPOSE To establish a rat model of neurotrophic keratopathy and to examine the effects of the combination of substance P (SP) and insulin-like growth factor (IGF)-1 on corneal epithelial barrier function and wound healing in this model. METHODS Corneal denervation was achieved by thermocoagulation of the ophthalmic branch of the trigeminal nerve. A modified Schirmer test was performed withou...

Background. Despite the significant development of modern anesthesiology, pain relief surgical patients is still unsatisfactory. Inadequate management causes psychological discomfort and complications. The combination general anesthesia with various options for local allows one to get closer solving problem pain. aim study was compare effect multicomponent balanced (intravenous + inhalation) an...

Clinical studies suggest that essential oil of Eugenia caryophyllata (Clove) buds (EOEC) is efficacious in the treatment of dental pain. In the present study, we investigated the analgesic and local anesthetic effects of EOEC and its possible mechanisms of action in acute corneal pain in rats. EOEC was extracted by hydro-distillation in a Clevenger type apparatus from clove buds. The acute corn...
