Congenital anomalies, such as absence, hypoplasia, bifurcation, or reduplication of various extraocular muscles, including lateral rectus muscles have been reported previously. We report a 5-year-old girl who had posteriorly malinserted lateral rectus at 15 mm from the limbus in the right eye with multiple associated ocular and systemic congenital malformations.

The normalization process is important to determine the best approach for normalizing electromyographic signals from respiratory muscles in healthy subjects and those with ALS. The aim of this study is to compare different methods of normalizing the sEMG signal of respiratory muscles in both healthy subjects and those with Amyotrophic Lateral Sclerosis (ALS). This cross-sectional study was conducted in 67 subjects (50 healthy and 17 with ALS).

Extraocular muscle (EOM) enlargement occurs in both acromegaly and Graves' disease, but the degree and pattern of enlargement have not been directly compared in these patient groups. This study investigated whether acromegaly and Graves' orbitopathy (GO) are associated with different patterns of EOM enlargement at the time of diagnosis. Retrospective cohort.

Purpose: To examine the anatomy of the orbital septum posterior to the medial canthal tendon area.
Materials And Methods: We performed 3 anatomical dissections in the present study. The first one was a microscopic study in which exenterated specimens from 6 Japanese cadavers (age from 77 to 93 years at death) were cut inferno-horizontally, including the Müller muscle, medial rectus pulley, and lateral rectus pulley, and stained with Masson's trichrome.

Purpose: To review evidence supporting proposed anatomic etiologies of involutional entropion and propose additional potential contributing factors.
Methods: A literature review was performed to identify publications describing possible etiologies of involutional entropion. The author's clinical observations and information supporting new proposed causes are presented.

Background: Endoscopic endonasal techniques, initially developed for sinonasal tumor resection, have revolutionized the approach to orbital lesions. The emergence of endonasal orbital tumor surgery has prompted anatomical studies focusing on the medial orbit, yet there remains a lack of literature on maneuverability lateral to the optic nerve (ON), with current feasibility assessments relying primarily on the plane of resectability (POR).
Methods: Bilateral anatomical dissections were conducted on four latex-injected human cadaveric heads using an endoscopic medial and inferior orbitotomy and superomedial displacement of the inferior rectus muscle (IRM) to access the inferolateral intraconal quadrant.
