Background/purpose: To evaluate outcomes in pediatric patients undergoing lensectomy, posterior capsulotomy, and triamcinolone-assisted vitrectomy for congenital cataract.
Methods: This retrospective study included 34 patients younger than 72 months who underwent lensectomy, posterior capsulotomy, and triamcinolone-assisted vitrectomy with or without intraocular lens (IOL) implantation for cataract at the National Taiwan University Hospital from July 2006 to December 2012.
Results: Fifty-one eyes from 34 patients with cataract (unilateral in 17 patients, bilateral in 17 patients) were included. The mean age at surgery was 26.74 months (range: 2-72 months). The mean postoperative follow-up was 27.8 months (range: 6-72 months). Primary IOL implantation was performed in 25 eyes, 21 of which had the IOL implanted in the capsular bag. Fifty eyes had a central round pupil. The median logarithm of the minimum angle of resolution visual acuity was 0.3 in patients with unilateral cataract and 0.1 in those with bilateral cataract. Three eyes (5.9%) developed visual axis opacification (VAO) and required further surgery. Univariate analysis using Fisher's exact test indicated that surgery in the first 12 months of life was significantly associated with development of VAO (p=0.047). The incidence of postoperative VAO was approximately 15.8% in this age group.
Conclusion: Triamcinolone-assisted vitrectomy can be used in pediatric cataract surgery without serious long-term adverse effects. While the incidence of VAO is low, it appears unavoidable in approximately one-sixth of patients who undergo surgery before 12 months of age.

Background: Retinal detachment (RD) is common (23%-40%) in eyes with uveal coloboma due to early vitreous syneresis, inherent defects at the locus minoris resistentiae, and breaks in intercalary membrane (ICM).[1] Managing eyes with coloboma RD is difficult due to complexity of accessing and repairing retinal breaks. In RD surgeries, tamponade agents are used to provide surface tension across retinal breaks to prevent further fluid flow into the subretinal space until the effect of retinopexy is permanent.

Purpose: To develop a machine-learning image processing model for three-dimensional (3D) reconstruction of vitreous anatomy visualized with swept-source optical coherence tomography (SS-OCT).
Methods: Healthy subjects were imaged with SS-OCT. Scans of sufficient quality were transferred into the Fiji is just ImageJ image processing toolkit, and proportions of the resulting stacks were adjusted to form cubic voxels.
Femtosecond laser-assisted successful management of subluxated cataractous lens with vitreous in anterior chamber.

Femtosecond laser-assisted cataract surgery was performed in a case of posttraumatic cataract with six clock hours subluxation and vitreous in the anterior chamber (AC). Femtosecond laser pretreatment allowed a closed-chamber creation of corneal incisions, capsulotomy, and lens fragmentation with minimal sudden lens-diaphragm movements and zonular stress. Integrated imaging systems allowed customization of the size and position of capsulotomy and nuclear fragmentation, based on the extent and site of subluxation.

Aims: To determine hyaloid-retinal relationship in primary rhegmatogenous retinal detachment during vitreous surgery.
Methods: This is a prospective, interventional study of patients (n = 72) undergoing triamcinolone-assisted 25G vitreous surgery for primary rhegmatogenous retinal detachment. Hyaloid-retinal relationship was noted intraoperatively to identify regions and patterns of firm attachment and was classified into subgroups.
