Importance
Floppy eyelid syndrome “plasty” (FESplasty) is a surgical technique that addresses underlying superior tarsal plate and lateral canthal instability in floppy eyelid syndrome (FES) and aims to restore normal anatomical and physiological function to the upper eyelid.
Background
To describe the use of FESplasty in the surgical management of FES, and to report outcomes in an initial patient cohort.
Design
Retrospective study.
Participants
Seven patients (nine eyelids) with FES undergoing FESplasty.
Methods
A single surgeon (G.W.) performed all procedures. FESplasty utilizes a periosteal flap based at the inferolateral orbital rim, and applied to the anterior surface of the upper tarsal plate. It is combined with a titrated shortening procedure of the upper eyelid. Patient demographics, comorbidities and ocular symptoms and signs were recorded preoperatively. Pre‐ and postoperative upper eyelid distractibility were graded and documented.
Main Outcome Measures
Postoperative improvement in upper eyelid distractibility and symptomatology, operative complications and FES recurrence.
Results
FES symptoms and upper eyelid laxity improved at last follow‐up (average 24 weeks) in all patients, with no FES recurrences after a maximum follow‐up of 36 weeks. One patient, in whom FESplasty exacerbated his pre‐existing aponeurotic ptosis, required definitive ptosis surgery subsequently. There was one case of postoperative wound infection. Obstructive sleep apnoea was present in four of the seven patients. The remaining three patients were awaiting assessment.
Conclusions and Relevance
FESplasty is likely to confer long‐term effective stabilization of the lateral canthal tendon, lateral commissure and superior tarsal plate. Anatomical and functional results appeared to have been successfully achieved.
Compression of anterior visual pathway (AVP) structures by intracranial arteries is observed not infrequently on neuroimaging. Whether or not such compression results in damage to these structures, however, remains unclear. This information is important to define as AVP compression by intracranial arteries may be a causative factor in patients with otherwise unexplained visual dysfunction. In a single centre, 37 patients with evidence of intracranial artery AVP compression demonstrated on magnetic resonance imaging were identified by retrospective review of case records over the period 2011-2017. Variables were collected, including patient demographics, visual acuity, visual fields, pupillary reactions and optic disc appearance for patients in the case series. Visual field deficits correlated with compression sites in the 37 patients examined. Internal carotid artery-optic nerve compression was the most frequent (unilateral compression n = 9, bilateral compression n = 14), followed by chiasmal compression by the anterior cerebral artery (n = 8) and a combination of optic nerve and chiasmal compression (n = 5). Visual acuity and visual fields were stable on follow-up (mean 4 years) in 24 of 26 cases (93%). We conclude that AVP compression by intracranial arteries may be a causative factor in unexplained visual dysfunction. The visual defects are largely non-progressive.
Lymphocytic hypophysitis (LYH) is a neuroendocrine disorder characterised by autoimmune inflammation of the pituitary gland with varying degrees of pituitary dysfunction, visual field defects and ocular motility disturbance. The authors report an interesting case of a 50-year-old woman presenting with intermittent bilateral abduction deficits. Neuroimaging and histopathological findings are presented. To the authors' knowledge, this is the first report of recurrent horizontal binocular diplopia and complete bilateral internal carotid artery occlusion in association with LYH.
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.
