Some ocular fundus features, in light of a patient's history and visual symptoms, may suggest a specific mechanism or aetiology of the visible disc oedema, but current criteria can at most enable an educated guess as to the most likely cause. In many cases only the clinical evolution and ancillary testing can inform the exact diagnosis. The development of ocular fundus imaging, including colour fundus photography, fluorescein angiography, optical coherence tomography, and multimodal imaging, has provided assistance in quantifying swelling, distinguishing true optic disc oedema from pseudo-optic disc oedema, and differentiating among the numerous causes of acute optic disc oedema. However, the diagnosis of disc oedema is often delayed or not made in busy emergency departments and outpatient neurology clinics. Indeed, most non-eye care providers are not able to accurately perform ocular fundus examination, increasing the risk of diagnostic errors in acute neurological settings.

Frontal facial photographs of patients who were greater than 60 years of age and had been diagnosed with sagging eye syndrome or intermittent exotropia were evaluated for three characteristics including sunken upper eyelids, blepharoptosis and baggy lower eyelids. The patients were compared to normal controls and a scoring system was used to grade the degree of these three characteristics. A total of 86 patients were included in the study. Of these, 23 were diagnosed with sagging eye syndrome, 28 were diagnosed with intermittent exotropia and 35 were in the control group. All patients were Japanese. The authors noted that only sunken upper eyelids, as opposed to blepharoptosis and baggy lower eyelids, were significantly associated with sagging eye syndrome. This contrasts with previous reports of sagging eye syndrome being associated with blepharoptosis. They also report that baggy lower eyelids were significantly associated with intermittent exotropia.
