Purpose: Online health information seekers may access information produced by artificial intelligence language models such as ChatGPT (OpenAI). The medical field may pose a significant challenge for incorporating these applications given the training and experience needed to master clinical reasoning. The objective was to evaluate the performance of ChatGPT responses compared to human oculofacial plastic surgeon (OPS) responses to FAQs about an upper eyelid blepharoplasty procedure.

Purpose: Müller muscle-conjunctival resection (MMCR) is a popular posterior/internal surgical approach to cases of mild to moderate blepharoptosis with good levator function. MMCR necessitates the removal of healthy conjunctiva and exposes the cornea to suture material. The goal of this study is to describe a novel sutureless conjunctiva-sparing Müllerectomy (CSM) surgery and demonstrate its long-term efficacy, efficiency, and safety.

Article Synopsis
  • This study evaluates facial asymmetry in children with unilateral congenital ptosis through a retrospective analysis of ptosis repair cases from 2017 to 2020.
  • It utilizes ImageJ software to gather facial measurements from preoperative photos and compares the ptotic side to the non-ptotic side using statistical methods.
  • Findings reveal that the affected side has smaller facial dimensions and more often displays a head tilt towards the ptotic side, suggesting a pattern of facial asymmetry related to the condition.

Purpose: Hemodynamic changes surrounding the optic nerve head are known to occur in thyroid-related orbitopathy (TRO). This pilot study explores the capillary and non-capillary peripapillary perfusion changes of the retina in TRO eyes without dysthyroid optic neuropathy (DON) using optical coherence tomography angiography (OCT-A).

Methods: Non-capillary and capillary peripapillary perfusion densities were calculated using single 4.

Epiphora from monocanalicular obstruction is commonly treated with canaliculoplasty, with or without dacryocystorhinostomy, or with conjunctivodacryocystorhinostomy with Jones tube placement. We describe two patients with epiphora due to isolated monocanalicular obstruction without concurrent nasolacrimal duct obstruction who underwent endoscopic dacryocystorhinostomy; both cases had previously failed canaliculoplasty, and both reported significant improvement in epiphora postoperatively. We hypothesize this is due to decreased resistance through the lacrimal drainage system allowing for increased flow through the patent canaliculus and shortened lacrimal apparatus.

Purpose: To review the clinical radiographic and histopathologic findings associated with orbital glial heterotopia.

Methods: A literature search in PubMed and Scopus was performed to include all articles published in English between 1980 and January 1, 2019. A case series including 29 case reports of 29 patients, as well as the authors' 2 cases, were considered in the literature review.

Purpose: The aim of this study was to measure volumes of normal lacrimal glands (LGs) using magnetic resonance imaging in African-Americans (AAs) and whites and to evaluate relationships of LG volumes to demographic factors.

Methods: A retrospective chart review was performed searching for "optic neuropathy" and "optic neuritis," cross-referencing patients who had orbital MRI with and without contrast. Cases were excluded with known history of orbital trauma or surgery, previous diagnoses known to affect LG size, and poor image quality.

Plasmacytoma is an uncommon presentation of plasma cell malignancy, especially in the absence of multiple myeloma. Orbital plasmacytomas generally originate from bone, although few cases in the literature report orbital extramedullary plasmacytomas. We present the case of a 68-year-old man found to have a solitary extramedullary plasmacytoma in the lateral rectus muscle without further evidence of multiple myeloma.

Article Synopsis
  • This study explored the effectiveness of a 1,064 nm Nd:YAG laser for improving the appearance of scars after direct browplasty surgery in nine patients.
  • Patients received laser treatments on one side of their brow while the other side served as a control, and they rated their scars on various aspects before and after treatments.
  • Results showed significant improvement in scar appearance by the fifth and sixth treatments according to patient self-reports, although masked observers did not find the same level of improvement; side effects were mostly mild and temporary.
