Ophthalmology is a branch of medicine that we, as ophthalmologists, regard as an elite branch of medicine and others, such as general surgeons and physicians, often consider as a minor and sometimes easy discipline. As a result of this misdirected preconception, a general practitioner, consultant or physician may not feel it necessary to fully inform us of a patient's health record because they do not consider that ophthalmic medications could, potentially, carry with them serious, sometimes life threatening side effects, if used inappropriately.
Brown syndrome is defined as an ocular motility disorder, characterized by an inability to elevate the adducted eye actively or passively. The causes can be congenital or acquired, and the problem can be permanent or transient. Clinically, Brown syndrome is characterized by a significant limitation of elevation in the adducting position that occurs in the majority of cases and improved elevation is usually apparent in the midline, with generally normal elevation in abduction. Exodeviation (V pattern) can occur on elevation in the midline. Many patients are orthophoric in the primary position, although sometimes hypotropia can develop with a compensatory face turn towards the opposite eye. A positive forced duction test is usually the hallmark of Brown syndrome.
