Purpose: This study aimed to compare the effectiveness of 3 artificial intelligence language models-GPT-3.5, GPT-4o, and Gemini, in delivering patient-centered information about thyroid eye disease (TED). We evaluated their performance based on the accuracy and comprehensiveness of their responses to common patient inquiries regarding TED.

Purpose: To assess the influence of Botulinum neurotoxin A (BoNT-A) injection on meibomian gland function and dry eye in patients diagnosed with Blepharospasm (BPS) and Hemifacial spam (HFS).

Methods: Adult patients aged 18 years or older who suffer from periocular dystonia, and were treated with BoNT-A injections, were recruited in this interventional prospective study between 2023 and 2024. Each patient was followed up for a period of three months.

Article Synopsis
  • The treatment of tear troughs, or the medial infraorbital region, is gaining popularity due to its minimally invasive nature and the use of soft tissue fillers injected with a cannula.
  • In a study involving 123 participants, the clinical outcomes were evaluated six months after injecting an average of 0.26 cc of filler per tear trough, showing significant improvements in depth, hyperpigmentation, fat pseudo-prolapse, and wrinkle severity (all p < 0.001).
  • The findings suggest that this injection technique is effective for reducing the appearance of hollowing under the eyes with few adverse effects, using a method that emphasizes bridging gaps rather than filling completely.

Objectives: To examine the effects of percutaneous tetracycline delivery to the malar area using a thermomechanical device (Tixel) in patients suffering from festoons.

Methods: This retrospective study included patients who underwent combination treatment with a thermomechanical device (Tixel) followed by application of topical tetracycline 1% at two private clinics between 2019 and 2023. Demographic and medical data, treatment parameters along with before and after treatment photographs were retrieved retrospectively.

Purpose: To investigate the effect of ptosis surgery on dry eye disease as measured by dry eye parameters and meibomian gland function.

Methods: This prospective, case series study included patients with involutional ptosis with no prior history of dry eye disease who were scheduled for a levator aponeurosis advancement procedure. Dry eye evaluation included the ocular surface disease index (OSDI) questionnaire as well as objective measurements, which included meibomian gland loss measured by meibography, meibomian gland disease grading, tear breakup time (TBUT), corneal and conjunctival fluorescein staining, tear meniscus height, and Schirmer testing.

Background: Lower eyelid malposition can result from age-related changes, such as ectropion, or postsurgical changes, such as retraction after lower lid blepharoplasty. The current accepted treatment is surgical, but soft-tissue fillers have been used as well, with good outcome. The underlying anatomy, which is incompletely described, would be useful information for practitioners desiring to provide minimally invasive injections of the lower eyelid.

Background: Eyelid ptosis following periocular onabotulinumtoxinA (BoNT-A) treatment is a known complication that can be frustrating for both patients and practitioners. Iatrogenic blepharoptosis occurs due to local spread of the BoNT-A from the periocular region into the levator palpebrae superioris muscle. Although injectors should have a thorough understanding of the relevant anatomy in order to prevent it, BoNT-A induced ptosis can occur even in the most experienced hands.

Purpose: To examine the effects of treatment with a thermomechanical skin device to the eyelid area on the clinical signs and symptoms of patients who suffer from dry eye disease (DED) secondary to meibomian gland dysfunction (MGD).

Methods: Forty patients aged 45 years or older with DED due to MGD were recruited. Both eyes (n = 80) of each patient received three treatments with the Tixel device (Novoxel®, Israel), with each treatment separated by a 2-week period.

Purpose: To evaluate the use of meibography as an objective measure of the effects of incision & curettage (I&C) chalazion surgery on meibomian gland loss and morphology as well as dry eye syndrome.

Methods: This prospective, interventional clinical study included adult patients with a primary chalazion which persisted despite conservative treatment. All patients underwent I&C surgery.

Objective: To evaluate the incidence of consecutive exotropia following bilateral medial rectus muscle recession surgery (BMR) for esotropia using non-absorbable compared with absorbable sutures in children undergoing strabismus surgery.

Methods: A retrospective cohort study of all children with esotropia who underwent BMR by a single surgeon in a tertiary public hospital. As of February 2018, only non-absorbable sutures were used.

Background: Retrospective cohort study evaluating long term keratoconus progression amongst cross-linking (CXL) treated pediatric patients in the treated and the fellow untreated eyes.

Methods: Data on 60 eyes of 30 patients, 18 years old or younger, who underwent CXL in at least one eye was collected and analyzed. Follow-up measurements taken from the treated and untreated eye up to 7 years after CXL treatment, were compared to baseline measurements.

Purpose: To assess structural risk factors for intraoperative floppy iris syndrome (IFIS) available on preoperative examination before cataract surgery.

Methods: In this retrospective study, medical records of patients who underwent cataract surgery in Shamir Medical Center, between July and September 2019, were reviewed. Patients younger than 50 years, with preexisting ocular conditions affecting the pupillary size or anterior chamber depth (ACD), and combined procedures were excluded.

Purpose: Periocular inverted papilloma (IP) is a rare, locally aggressive tumor with a propensity for recurrence and malignant transformation. Historically treated via wide excision, this study examines the characteristics and management of periocular IP, comparing those confined to the nasolacrimal system with those invading the orbit.

Methods: An Institutional Review Board-approved, Health Insurance Portability and Accountability Act-compliant retrospective, comparative case series was conducted in patients with IP of the orbit or nasolacrimal system across 15 clinical sites.

Background: The anterior aspect of the auricle is a complex 3-dimensional structure. Each anatomical component in this region has an essential role in the aesthetic appearance of the ear and face. The reconstruction of defects in this region is challenging because of the lack of mobile, excess skin for primary closure, and the inability to skin graft overexposed cartilage.
