Chromatic vision and structural assessment in primary congenital glaucoma.

Primary congenital glaucoma is a rare disease that occurs in early birth and can lead to low vision. Evaluating affected children is challenging and there is a lack of studies regarding color vision in pediatric glaucoma patients. This cross-sectional study included 21 eyes of 13 children with primary congenital glaucoma who were assessed using the Farnsworth D-15 test to evaluate color vision discrimination and by spectral domain optical coherence tomography to measure retinal fiber layer thickness.

Is three-piece maxillary segmentation surgery a stable procedure?

Objective: : The number of three-piece maxillary osteotomies has increased over the years; however, the literature remains controversial. The objective of this study was to evaluate the skeletal stability of this surgical modality compared with that of one-piece maxillary osteotomy.

Methods: : This retrospective cohort study included 39 individuals who underwent Le Fort I maxillary osteotomies and were divided into two groups: group 1 (three pieces, n = 22) and group 2 (one piece, n = 17).

Sex and age biological variation of the mandible in a Portuguese population- a forensic and medico-legal approaches with three-dimensional analysis.

The medico-legal identification is based on a set of discriminatory characteristics between individuals in their biological, social, cultural, religious, legal and economic framework. The purpose of this study was to characterize the biological variation, regarding gender and age, in a Portuguese population. A three-dimensional (3D) analysis of 215 mandibles (7-20 years old) from the database of the Laboratory of Forensic Dentistry, Faculty of Medicine, University of Coimbra (CE-112/2019) was performed.

Three-dimensional comparison of mandibular morphology in young people with Treacher Collins syndrome and Pierre Robin sequence.

Introduction: Treacher Collins syndrome (TCS) and nonsyndromic Pierre Robin sequence (PRS) share mandibular deficiency as a similar clinical finding. This study aimed to compare the mandibular size and morphology of subjects with TCS and PRS.

Methods: Group TCS was composed of 17 subjects (7 male, 10 female) with a mean age of 11.

A Cleft-Customized Occlusal Rating System to Assess Orthodontic Occlusal Improvement in Patients With Unilateral Cleft Lip and Palate.

Objective: This study aimed to develop a new method to quantify occlusal improvement in patients with unilateral cleft lip and palate (UCLP) who had undergone orthodontic treatment and to evaluate its reproducibility.

Design: A panel of orthodontists decided on the relevance of different occlusal features to score initial and final 3-dimensional study models and panoramic radiographs. A subsequent subjective analysis was later performed by a local orthodontic panel.

Bone-anchored maxillary protraction long-term outcomes in UCLP.

This case report presents a 12-year-old boy with unilateral complete cleft lip and palate and severe maxillary retrusion treated with bone-anchored maxillary protraction (BAMP) therapy followed by fixed appliances. The follow-up period extended until the end of growth. Initially, the patient demonstrated a Goslon 4 interarch relationship with an overjet of -3.

Comparison Between Treacher Collins Syndrome and Pierre Robin Sequence: A Cephalometric Study.

Objective: The aim of this study was to compare the dentoskeletal pattern of Treacher Collins syndrome (TCS) and nonsyndromic Pierre Robin sequence (PRS).

Design: Retrospective.

Setting: Single center.

Facial and Nasolabial Aesthetics of Complete UCLP Submitted to 2-Stage Palate Repair With Vomer Flap.

Objective: To evaluate the aesthetics of nasolabial appearance and facial profile of children with unilateral cleft lip and palate (UCLP) submitted to 2-stage palate repair with vomerine flap.

Design: Retrospective.

Setting: Single center.

Comparison of anterior segment optical coherence tomography angiography and fluorescein angiography for iris vasculature analysis.

Purpose: The aim of this study is to perform imaging of irises of different colors using spectral domain anterior segment optical coherence tomography angiography (AS-OCTA) and iris fluorescein angiography (IFA) and compare their effectiveness in examining iris vasculature.

Methods: This is a cross-sectional observational clinical study. Patients with no vascular iris alterations and different pigmentation levels were recruited.

Aqueous misdirection syndrome in persistent fetal vasculature (PFV).

We report a case of a 5-year-old girl with persistent fetal vasculature who presented with unilateral acute angle closure caused by aqueous misdirection syndrome that was apparently associated with regression of cycloplegia. Initial treatment with topical steroids, anti-glaucomatous drops, and atropine showed insufficient control of the intraocular pressure (IOP). Surgical treatment with lensectomy and vitrectomy resulted in satisfactory IOP control and no complications at the 6-month follow-up.

Risk of developing palatally displaced canines in patients with early detectable dental anomalies: a retrospective cohort study.

Objective: To estimate the risk of PDC occurrence in children with dental anomalies identified early during mixed dentition.

Material And Methods: The sample comprised 730 longitudinal orthodontic records from children (448 females and 282 males) with an initial mean age of 8.3 years (SD=1.

Comparison of Optical Coherence Tomography Angiography and Fluorescein Angiography for the Identification of Retinal Vascular Changes in Eyes With Diabetic Macular Edema.

Background And Objective: To compare the visualization of microaneurysms (MA) and the foveal avascular zone (FAZ) area using optical coherence tomography angiography (OCTA) versus fluorescein angiography (FA) in patients with diabetic macular edema (DME).

Patients And Methods: Patients were prospectively recruited for same-day imaging on spectral-domain OCTA and FA. OCTA images were automatically segmented into superficial (sOCTA) and deep (dOCTA) capillary plexuses.
