A 58-year-old white female noted a lesion on her left lower eyelid, present for 3 months. Examination disclosed a dark-blue, subepithelial, smooth mass along the cilia near the punctum. The lesion did not transmit light and was thought to be a solid mass, such as a deep-blue nevus or melanoma versus a cystic mass with internal debris. Ultrasound biomicroscopy showed a fairly circumscribed echolucent mass measuring 3.2 x 3.5 mm suggestive of a cyst with numerous internal echo impedances. Following resection, histopathologic evaluation disclosed a cyst lined by a dual layer of eccrine sweat ductal epithelium, consistent with eccrine hidrocystoma. ⋯ Eyelid hidrocystomas can be pigmented and can be confused clinically with melanocytic tumors. Ultrasound biomicroscopy can provide helpful diagnostic information about the internal architecture of such lesions.

Most optic neuropathies do not have effective treatments. Examples are ischemic optic neuropathy, Leber hereditary optic neuropathy, optic neuritis, and traumatic optic neuropathy. In some cases, the pathophysiology of the optic nerve injury is not fully understood. ⋯ In optic neuropathies, the corresponding neuron is the retinal ganglion cell. These cells are unable to divide, and optic neuropathies irrevocably result in their death; therefore, the primary target of neuroprotection are retinal ganglion cells and their axons. This review emphasizes that most optic neuropathies are axonal and thus good targets for neuroprotection.

Greek mythology: the eye, ophthalmology, eye disease, and blindness.
In distant eras, mythology was a form of expression used by many peoples. A study of the Greek myths reveals concealed medical knowledge, in many cases relating to the eye. ⋯ The study of mythological references to the eye reveals reliable medical observations of the ancient Greeks, which are concealed within the myths.
