“…It has been shown that the loss of the corneal lacrimal neurosensory circuit, as in this phthisical eye, leads to relative hyposensitization, lacrimal gland atrophy, decrease tear production, and a low-flow system. 7 This point allows for the canalicular system of the phthisical eye to act as a donor site. In this low-flow system we presume that removal of a portion of the canalicular system will not lead to symptomatic epiphora.…”
This is the first reported case of successful canalicular transplantation. Although a single case report, the authors anticipate future success with this technique.

Orbital implant replacement with DFG was effective at relieving chronic ASP, and pain resolution was sustained in all cases. This surgical intervention may be a useful management option for patients in whom all detectable causes of chronic pain have been excluded and have failed medical pain management.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
