Purpose: Epiretinal membrane is a macular disorder leading to metamorphopsia and decreased visual acuity. The aim of the present study was to assess the possible effects of air tamponade, balanced salt solution (BSS), and combined phacoemulsification on functional and anatomical outcomes.
Procedures: This prospective exploratory analysis included 72 eyes with idiopathic epiretinal membranes, scheduled to undergo 23-G pars plana vitrectomy with membrane peeling. Air tamponade or BSS was used in all cases. Optical coherence tomography (OCT) imaging was performed intraoperatively, and follow-up including visual acuity testing and OCT measurements was conducted until 3 months postoperatively.
Results: Mean best-corrected visual acuity improved between +2.1 and +3.1 letters, and mean central subfield thickness of the macula decreased between -29.6 and -76 µm in the examined groups, without significant differences between the air tamponade and BSS groups. There was no significant difference in the presence of intraretinal cystoid changes between the groups.
Conclusions: The use of air tamponade did not show any significant differences in the anatomical and functional postoperative results compared to BSS. Furthermore, phacovitrectomy did not result in significantly more intraretinal cystoid changes 3 months after surgery.

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: Air as a tamponade in pars plana vitrectomy (PPV) is increasingly preferred due to its quick rehabilitation time. We aim to examine the factors affecting the absorption time of air tamponade.
Method: The study included 82 eyes from 78 patients who underwent PPV with air used as the tamponade.
Article Synopsis
- The study developed a new surgical technique for treating full-thickness macular holes (MH) associated with proliferative epiretinal structures, assessing its effectiveness in a clinical setting.
- It involved 34 patients, with one group undergoing the new technique featuring an inverted internal limiting membrane (ILM)/epiretinal membrane (ERM) flap, and the other group using conventional peeling techniques.
- Results showed that the new technique led to better visual acuity and more significant improvements in central retinal sensitivity, with a higher success rate in closing macular holes compared to traditional methods.

Purpose: To report outcomes of pars plana vitrectomy (PPV) with air tamponade for primary rhegmatogenous retinal detachment (RRD) and investigate the impact of vitreous cortex remnants (VCR) on surgical outcomes.
Methods: A retrospective review of 900 patients treated for uncomplicated primary RRD between 2007 and 2020. Exclusion criteria included axial length > 26 mm, prior retinal surgery, giant retinal tear, PVR grade > B, and inadequate follow-up.

Methods: Seven consecutive patients (8 eyes) with a diagnosis of LMH underwent a pars-plana vitrectomy with PRP injection under air tamponade.
