Article Abstract
Purpose: To evaluate the performance of the 3D visualization system with coaxial illumination (3D-C) in treating cataract patients with corneal opacities.
Design: Prospective, comparative interventional case series.
Subjects: This study included patients with cataract and corneal opacities that underwent phacoemulsification.
Inclusion Criteria: senile cataract cases with stable corneal opacity of grade 2-3 (Corneal Haze classification).
Exclusion Criteria: (1) prior intraocular surgical interventions excluding corneal procedures; (2) ocular complications such as active corneal infections, glaucoma, lens dislocation, vitreoretinal diseases, or uveitis.
Methods: This two-part assessment for visualization comprised of an objective analysis utilizing surgical video images and a subjective survey collecting feedback from the surgeons. Data of each eye were obtained with 2 approaches: 3D visualization system with coaxial illumination (3D-C) and 3D visualization system with standard illumination (3D-S).
Main Outcome Measures: Objective analysis: red reflex and contrast assessment of images in the followed steps: before the surgery, capsulorhexis, nucleus groove, and cortex aspiration. Subjective survey: scales from five experienced surgeons at eight parameters: red reflex, depth of field, corneoscleral limbus clarity, capsulorhexis, hydrodissection, nucleus groove, cortex removal, and ophthalmic viscosurgical devices removal.
Results: The red reflex values of the 3D-C group were 207.7 ± 26.2, 195.7 ± 24.6, 154.3 ± 18.6, and 179.7 ± 21.6 in the steps of surgery beginning, capsulorhexis, nucleus groove, and cortex aspiration, which were markedly greater than those of the 3D-S group (P ≤ .001). Contrast values of the aforementioned steps were higher in the 3D-C group than in the 3D-S group (P ≤ .01). All surgeons emphasized that the intraocular tissue below corneal opacity was more clearly identified during various stages of the surgery by intensifying intraoperative visualization through the 3D-C approach.
Conclusions: The 3D-C approach significantly enhanced red reflex and contrast within the pupillary area during phacoemulsification. The utilization of the 3D-C approach is beneficial for performing surgical maneuvers in cataract patients with corneal opacities.

: Nemaline myopathy is a rare congenital neuromuscular disease associated with progressive weakness and frequent respiratory complications. In emergency situations, families often serve as the first and only responders. The aim of this study is to explore how parents in Spain care for children with nemaline myopathy during emergency situations, focusing on the clinical responses performed at home and the organizational challenges encountered when interacting with healthcare systems.

Purpose: To describe the gross morphology of the levator palpebrae superioris (LPS) muscle complex in severe congenital ptosis with poor levator function (LF) and to evaluate the surgical outcomes when levator surgery was performed based on intraoperative factors.
Methods: This is a retrospective, interventional case series that includes children having simple severe congenital ptosis with LF ≤ 4 mm for whom levator muscle surgery was performed rather than preplanned frontalis suspension based on the intraoperative LPS muscle evaluation. The collected data included: demographics; ptosis measurements, including margin reflex distance 1 and LF; morphological appearance of LPS muscle and its aponeurosis (levator aponeurosis); surgical technique, and outcomes.

Background: Vision impairment in children, the leading causes of which are untreated refractive errors and amblyopia, is a significant global health issue. This study focuses on the current practices of vision impairment screening of children and adolescents by family medicine physicians in the Eastern Region of Saudi Arabia. The aim of this study was to evaluate the methods used by family medicine physicians to screen vision and identify areas requiring improvement to enhance early detection and treatment.
