PURPOSE To determine the shifts of the main corneal reference points in dependence of the chosen centration axis for the treatment. SETTING Federal Institute of Technology Zurich, Institute of Biomedical Engineering, Zurich, Switzerland. METHODS Computer simulations were performed on several variants of the Gullstrand-Emsley schematic eye, which was modified by an off-axis fovea. Refractive...

level, pupil reaction, and corneal reflex. However, there were many discrepancies in individual patients so that the vestibulo-ocular reflex afforded useful information additional to that obtained from traditional tests. Bilateral abnormal motor activity or absent pupil reactions were often associated with relatively unimpaired vestibulo-ocular reflex responses. There was no correlation between...

Abstract General anaesthesia is accompanied by a loss of the blink reflex, decreased tear production, inability to close eye and stability film. Protection with corneal lubricant standard during general anaesthesia, but clear recommendations are missing. Moreover, anaesthetic event may trigger other factors that increase susceptibility ulceration. In this case report, we describe clinical bilat...

Histopathologic ally in patient with diabetes the basement membrane is fragile cornea which leads to recurrent corneal erosion. it was observed that reflex tearing decreased & associated ocular surface diseases a state of dryness eye diabetic patient. There close relationship between retinopathy and Kerato conjunctivitis Sicca (P< 0.006) no laser Rx comparison treatment. The present stud...

PURPOSE To report a new technique in the repair of lower eyelid malposition using dermis fat as a posterior lamellar spacer graft. DESIGN Retrospective, consecutive, nonrandomized interventional case series. PARTICIPANTS Eleven patients who underwent surgical correction for symptomatic lower eyelid malposition using dermis fat as a spacer graft. METHODS Patients with symptomatic lower eye...

The cornea is one of the most densely innervated and sensitive tissues in the body. In addition to their important sensory functions, corneal nerves induce reflex tear production, blinking, and the release of trophic factors - all of which combined help to maintain the structural and functional integrity of the surface of the eye. Consequently, damage to corneal nerves as a result of disease, s...

BACKGROUND Trigeminal neuralgia (TN) is a pain appearing in the ophthalmic (V1), maxillary (V2), and mandibular (V3) trigeminal branches. Pharmacologic treatment is the first line for TN; however, many patients prefer to receive minimally invasive treatment rather than medicine because of intolerable side effects. Thermocoagulation radiofrequency (TRF) is a minimally invasive treatment that has...
