Review Case Reports
Charles Bonnet syndrome: case presentation and literature review.
Charles Bonnet syndrome (CBS) is an under-recognized and under-reported disorder that involves visual hallucinations in visually impaired individuals. These patients have intact cognition, do not have hallucinations in any other sensory modalities, and retain insight into the unreal nature of their hallucinations. ⋯ Optometrists should be aware of the potential for visual hallucinations in patients with visual impairment. Early recognition by clinicians of the symptoms of CBS, and sharing proper information, treatment, and advice, can alleviate distress or suffering experienced by patients with CBS.

Discrete extraocular muscle (EOM) metastasis is rarely reported. Clinical signs and symptoms of EOM metastasis can often be indistinguishable from primary idiopathic orbital myositis, posing a significant clinical challenge. ⋯ This case illustrates discrete adenocarcinoma metastasis of an EOM, initially displaying characteristics predominantly consistent with orbital myositis. There is a paucity of epidemiologic data on EOM cancer, and clinical characteristics are derived only from a selection of case reports in the literature. Thus, the predominant features of global orbital metastatic cancer versus primary inflammation are highlighted in this presentation. This case shows that the variable characteristics of each process prohibit identification of any clinical feature that would prove pathognomonic for either disorder. The varied practice philosophies and standard of care regarding the proper time to biopsy are reviewed. This case shows the importance of early referral for orbital biopsy, even in the presentation of isolated, discretely edematous, and painful EOM enlargement.
