Purpose:
Currently, no consensus exists on the role of optical coherence tomography (OCT) imaging in the setting of acute posterior vitreous detachment (PVD). The authors outline the clinical utility of OCT in the management of acute PVD and its co…
Purpose:
To calculate the retinal surface alternatively in contact with gas and aqueous because of fluid sloshing during daily activities such as ocular saccade, turning the head, standing up, and being a passenger of a braking car.
Methods:
Fluid dynamics of aqueous and gas tamponade was reproduced using computational methods using the OpenFOAM open-source library. The double-fluid dynamics was simulated by the volume of fluid method and setting the contact angle at the aqueous–gas–retina interface.
Results:
Sloshing increased the retinal surface in contact with aqueous by 13% to 16% regardless of fill rate and standing up determined the largest area of wet retina, followed by car braking, head rotation, and ocular saccade (P
Purpose:
To evaluate the efficacy of anterior segment optical coherent tomography (AS OCT) in estimating the length of the pars plana and optimizing the sclerotomy entry site in vitrectomy for highly myopic eyes, facilitating membrane peeling.

Purpose:
To report on the feasibility of 27-gauge (G) vitrectomy for pediatric patients.
Methods:
This study is an international, multicenter, retrospective, interventional case series. Participants were patients 17 years or younger who unde…
Purpose:
The need for suturing leaking sclerotomies have not been eliminated completely in transconjunctival sutureless vitrectomy (TSV). This study aims to describe a novel technique for 23-gauge (G) sclerotomy closure in TSV surgery and discuss its effectiveness.
Materials and Methods:
Two hundred and thirty cases of 180 patients who underwent 23G TSV with various diagnoses were included to the study. Cases with connective tissue diseases, thin sclera, and significant conjunctival and scleral scarring were excluded. Nonperforating intrascleral stabbing (NIS) was performed to leaking 23G sclerotomies (n = 650) and 27G chandeliers (n = 84). Demographics, rate of sclerotomy closure with NIS procedure, the need for suturing, and complications of the procedure were recorded.
Results:
The overall success of NIS was found to be 91.0% in sclerotomies. Although 9.1% of sclerotomies required sutures, 592 of the 650 sclerotomies could be closed with NIS procedure (P
Purpose:
To report outcomes of pediatric patients with combined hamartoma of the retina and the retina pigment epithelium followed up conservatively or after pars plana vitrectomy.
Methods:
This retrospective multicenter study included 62 eyes of 59 pediatric patients with combined hamartoma of the retina and the retina pigment epithelium from 13 different international centers with an average age of 7.7 ± 4.7 (0.3–17) years at the time of the diagnosis and having undergone pars plana vitrectomy or followed conservatively. At baseline and each visit, visual acuity values, optical coherence tomography for features and central foveal thickness, and tumor location were noted. Lesions were called as Zone 1, if it involves the macular and peripapillary areas, and the others were called as Zone 2 lesions.
Results:
Twenty-one eyes of 20 patients in the intervention group and 41 eyes of 39 patients in the conservative group were followed for a mean of 36.2 ± 40.4 (6–182) months. Best-corrected visual acuity improved in 11 (68.8%) of 16 eyes in the intervention group and 4 (12.9%) of 31 eyes in the conservative group (P
Purpose:
To predict improvement of best-corrected visual acuity (BCVA) 1 year after pars plana vitrectomy for epiretinal membrane (ERM) using artificial intelligence methods on optical coherence tomography B-scan images.
Methods:
Four hundre…
