Ocular Complaints, Disease, and Emergencies in the General Medical Setting.

Primary care physicians see nearly half of all clinical visits, and 2% to 3% of those are for eye complaints. Taking a good ocular history is essential to establishing the diagnosis. Patient complaints fall into several categories including visual change, redness, and pain. Primary care physicians can screen for patients at risk of vision loss from glaucoma, diabetes, and toxic medication and ensure that patients have appropriate eye evaluations. Examination techniques such as direct ophthalmoscopy, evaluation of the red reflex, eversion of the upper lid, checking pupillary response, and using fluorescein to stain the cornea are helpful in evaluating patients' ocular complaints.
