Purpose: To determine the relationship between marginal reflex distance (MRD-1) outcomes and the distance of levator aponeurosis advancement.
Methods: This retrospective observational study included patients with acquired unilateral aponeurotic ptosis, who underwent small-incision anterior levator advancement. The distance of levator advancement, and intra-operative MRD-1 in the sitting position, were analyzed to determine a correlation between the two.
: This study aims to compare the clinical findings, particularly symptomatic diplopia, associated with an inferomedial orbital strut fracture versus intact strut and to determine the clinical significance of the inferomedial orbital strut in patients with orbital floor and medial orbital wall fractures. : A 10-year retrospective observational study involving orbital blowout fracture cases was conducted in our institution. Patients with fractures of the orbital floor medial to the infraorbital groove and medial orbital wall, as seen on computed tomography (CT) scans, were included in this study.

Purpose: To present the demographics and clinical characteristics of pure (rim-sparing) orbital roof fractures.
Methods: This retrospective observational study used 10 years of data from a single institution. Patient age, sex, laterality, field of binocular single vision, associated injuries, and radiologic features were analyzed.
The aim of this study was to present the demographic and clinical characteristics of sports-related pure (rim-sparing) orbital blowout fractures and to analyze these differences by type of sport. Ten years of sports-related orbital fracture data were accumulated. Patients were classified into similar sports (i.

Methods: A retrospective observational study involving 956 sides from 940 pure orbital blowout fracture patients was conducted in our institution. Patients with concomitant orbital rim fracture and those with old orbital fractures were excluded.
Introduction: The aim of this study is to compare data on the incidence of pediatric orbital fractures before the onset of the coronavirus disease 2019 (COVID-19) pandemic and during the period of the pandemic in the Japanese population.
Methods: This retrospective, single-center, observational study including 225 patients (226 sides) aged ≤ 18 years old diagnosed with orbital fracture was conducted in our institution from March 2017 to April 2023. The study compared the incidence of pediatric orbital fractures in the pre-pandemic period from March 2017 to March 2020 and during the pandemic from April 2020 to April 2023.

Purpose: To report adult patients with an orbital trapdoor fracture with extraocular muscle entrapment.
Methods: We retrospectively reviewed 566 adult patients (>18 years) with a pure orbital fracture who were referred to us from January 2016 to May 2023. The following data were collected: age, sex, affected side, causes of injury, concomitant ocular injury and nasal bone fracture, presence or absence of oculocardiac reflex and infraorbital nerve hypesthesia, period from injury to surgery, follow-up period, and pre- and postoperative limitation of extraocular muscle motility and fields of a binocular single vision.
Purpose: To investigate the medial pretarsal adipose tissue thickness of the upper eyelid in the Japanese population.
Methods: Sixty-two whole upper eyelids were harvested from 35 Japanese cadavers and fixed in paraffin. The samples were cut into 5 µm sagittal microsections and stained with hematoxylin and eosin, as well as Masson's trichrome.
Introduction: The aim of the study was to report a rare case of lacrimal gland abscess.
Case Presentation: A 47-year-old woman noticed upper eyelid swelling on the right side 1.5 months before referral to our service.
This retrospective, observational study examined the surgical outcomes of bilateral inferior rectus (IR) recession in thyroid eye disease. Twelve patients who underwent bilateral IR muscle recession were included in the study. Surgical success was defined as patient achievement of the following conditions: (1) a postoperative angle of vertical ocular deviation of ≤3°; (2) a postoperative cyclotropic angle of ≤2°; (3) postoperative binocular single vision, including the primary position; and (4) postoperative enlargement of the field of binocular single vision.

This study aimed to compare the patient characteristics between patients with SHOF in the superotemporal quadrant and those with SHOF in other quadrants. This is a retrospective study of 45 patients with SHOF who were referred to our institution between January 2015 and January 2023 and 14 previously reported patients in published case reports of SHOF that were not located in the superotemporal quadrant.

Although orbital NF is rare, it is rapidly progressive and can easily lead to the loss of tissue and visual function, sometimes to a life-threatening extent. Prompt and adequate treatment has been a challenge yet remains quite essential.
