How long after my dilated eye exam can I drive?ĭuring dilation, your vision is blurred and you may experience sensitivity to light. It’s also especially important for people with diabetes to have a comprehensive dilated exam at least once a year. The exam may also show excessive cupping of the optic disc, the place where the optic nerve fibers exit the eye and enter the brain.Īccording to the National Eye Institute, it is recommended that you have a comprehensive dilated eye exam at age 50, or before, by an experienced ophthalmologist. In a person with glaucoma, the dilated exam may show changes in the shape and color of the optic nerve fibers. A comprehensive dilated eye exam is also critical for detecting glaucoma, a disease that damages the optic nerve, which carries information from the eyes to the brain.These AMD-related changes tend to cause deterioration of a small area of the retina called the macula, which is needed for sharp, central vision. In some cases, the exam may also show abnormal growth of blood vessels beneath the retina. In age-related macular degeneration (AMD), a common cause of vision loss and blindness in people over the age of 50, the exam may show yellow deposits called drusen or clumps of pigment beneath the retina.

The eye care professional may also see abnormal growth of blood vessels in the retina associated with diabetic retinopathy.

Trauma patients with GCS 3 persisting from the scene with bilaterally fixed dilated pupils have no appreciable chance of survival. Pre-hospital GCS scores, prior to the effects of intubation, sedation and paralysis should be given more attention when assessing prognosis in patients who are GCS 3 on admission.

Of the 57 patients who were GCS 3 at the scene of the accident, post-basic resuscitation and on admission, none survived. Time to hospital, mechanism of injury and pre-hospital haemodynamic parameters had no significant effect on survival. Four of the survivors had Glasgow Outcome Score (GOS) of 4 or 5. Of the 6 surviving patients, none had significant thoracoabdominal injuries.

There were 6 survivors who were all less than 28 years of age, had at least one GCS score above 3 in the pre-hospital phase and were more likely to have had an evacuable mass lesion on CT brain scan and undergo craniotomy. Ninety-three patients fulfilled the criteria for inclusion into the study. Pre-hospital assessment, hospital interventions and outcomes were determined. Pre-hospital management of these patients affects the true measurement of the GCS and other factors may affect pupillary status.Ī retrospective review was undertaken of all patients who were classified GCS 3 and had bilateral fixed dilated pupils on admission to a Level 1 Adult Trauma Centre between July 2001 and March 2005. Survival of patients with severe trauma presenting with Glasgow Coma Score (GCS) 3 and bilateral fixed dilated pupils is uncertain.
