Background: The purpose of this paper is to study the utility of adhesives (artificial-cyanoacrylate and biological-fibrin glue) for improving transconjunctival sutureless vitrectomy (TSV) sclerotomy closure competency.
Methods: Experimental and observer-masked study in which after performing TSV in cadaveric pig eyes, different adhesives were tested on sclerotomy entrances in order to determine if they improved closure competency in face of progressive intraocular pressure increase. In 76 eyes cyanoacrylate-treated sclerotomies were compared with sclerotomies in which no additional manoeuvre to aid closing was performed; in 76 eyes fibrin glue with no manoeuvre; and in the last 76 eyes, cyanoacrylate-treated sclerotomies were compared with fibrin glue-treated sclerotomies.
Results: A total of 228 eyes had a 23-gauge TSV performed. Both cyanoacrylate and fibrin glue treated sclerotomies achieved higher mean opening pressures when compared with nontreated sclerotomies in the same eye (p < 0.002). When cyanoacrylate was compared with biological adhesive in the same eye, no statistically significant differences were obtained (p = 0.216).
Discussions: This experimental study provides support for the possible role of adhesives in improving TSV sclerotomy closure competency in clinical practice.

Article Synopsis
- The paper aims to address comments on "Static and Dynamic Filler-Associated Tear Trough Deformities" while elaborating on the surgical techniques discussed.
- For patients with loose lower eyelids and poor skin, lateral canthopexy is recommended when using transcutaneous methods to improve results.
- In transconjunctival surgeries, the authors argue that both sutured and sutureless techniques are valid options despite common belief against conjunctival suturing, emphasizing the lack of strong evidence on this matter.
The Glowport - Illuminated vitrectomy trocar cannulas.

The use of small-gauge trocar cannulas during transconjunctival sutureless pars plana vitrectomy (PPV) facilitates the smooth transition of instruments into the posterior segment and reduces trauma. However, room lighting is routinely dimmed during PPV, thereby making cannula visualization difficult and hence compromising efficient instrument exchange. We report the use of a frugal, fluorescent "glow-in-the-dark" ring placed over vitrectomy cannulas to visualize the cannula entry, thereby providing a smooth and efficient instrument exchange.

The standard of care to treat small- and medium-sized macular holes (<400 µm diameter) consists of a conventional transconjunctival sutureless pars plana vitrectomy followed by ILM peeling and endotamponade, mainly with gas or in some cases with silicone oil, resulting in closure rates of over 90% and good functional results. Large (>400 µm diameter), chronic and persistent macular holes remain a surgical challenge since closure rates and functional results decrease with larger macular hole diameters. Various modifications of the conventional surgical technique were introduced to improve anatomic and functional success in refractory cases not suitable for conventional macular hole surgery.

Purpose: To evaluate and compare the clinical outcomes of three different methods of intraocular lens (IOL) implantation in the surgery of subluxated cataracts.
Methods: In this retrospective, comparative, clinical interventional study, the medical records of patients who underwent IOL implantation with sutureless 27-gauge needle-assisted transconjunctival intrascleral (Group 1), Z-suture knotless transscleral (Group 2), and Cionni capsular tension ring (Cionni-CTR) assisted (Group 3) simultaneously with subluxated cataract extraction between June 2010 and June 2022 were evaluated. Demographic characteristics, follow-up times, uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), spherical and cylindrical refractive values, and spherical equivalent (SE) values of three groups were compared.
Wound healing and postoperative management in paediatric patients following 27-Gauge Transconjunctival Sutureless Vitrectomy for vitreoretinal conditions.

The utilization of 27-G TSV, or 27-Gauge Transconjunctival Sutureless Vitrectomy, poses distinct difficulties in the context of paediatric patients, particularly those younger than 14 years old, on account of the dearth of exhaustive documentation concerning the efficacy and results of these operations. Therefore, this retrospective study was to evaluate the safety and efficacy of 27-G TSV in paediatric patients, with emphasis on management of intraoperative and postoperative complications and postoperative wound healing. A total of 54 eyes of 52 paediatric patients who underwent 27-G TSV at Sichuan Provincial People's Hospital were included in the study.
