The development of aggregation-induced emission (AIE) luminophores is a fascinating and promising topic in electrochemiluminescence (ECL) bioanalysis. Herein, the AIE-active but water-insoluble [Ir(bt)₂(acac)] (bt = 2-phenylbenzothiazole, acac = acetylacetonate) was encapsulated within poly(styrene-maleic anhydride) (PSMA) using a simple nanoprecipitation method. This encapsulation strategy could effectively limit the free motion of Ir(bt)₂(acac) and trigger the aggregation-induced electrochemiluminescence (AIECL) effect.

Aims: To compare the efficiency of scleral buckling (SB) and pars plana vitrectomy (PPV) with or without SB in patients with primary simple phakic fovea-splitting rhegmatogenous retinal detachment (RRD).
Methods: A retrospective case-control study included 101 patients aged <55 years diagnosed with phakic fovea-splitting RRD. The primary outcome was functional success, defined as achieving a postoperative logarithm of the minimum angle of resolution best-corrected visual acuity of 0.

E-selectin (CD62E) is an adhesion molecule expressed on the surface of endothelial cells (ECs) and its level increases significantly upon the stimulation of ECs by inflammatory factors. Quantitative analysis of CD62E is of great importance to early diagnosis and treatment of vascular diseases and hypertension. A new method for the determination of CD62E was developed using a portable pH meter in this work.

Retina
February 2025
Disha Eye Hospitals Pvt Ltd, Barrackpore, India.
Purpose: To develop a simple tool to remove retained submacular perfluorocarbon liquid bubbles (R-PFCL) and to inject recombinant tissue plasminogen activator safely in subretinal space in submacular hematomas.
Method: A retrospective, interventional study was performed where a simple homemade micro-viscous fluid control was developed to gain access to subretinal space in a controlled way. The rubber cap of the plunger of a 1-mL syringe was cut; this cut rubber cap of the plunger was fitted inside an empty 1-mL tuberculin syringe, and its end was fitted with the tubings of viscous fluid control of the vitrectomy machine.
A Novel Custom Bent 27-Gauge Needle-Guided Suture Snare Technique for Scleral Fixation of Posterior Chamber Intraocular Lenses.
Retina
February 2025
Department of Ophthalmology, Liyang Hospital of Chinese Medicine, Liyang, China.
Purpose: To describe a custom bent 27-gauge needle-guided suture snare technique for scleral fixation of posterior chamber intraocular lenses (PCIOL).
Methods: An 8-0 polypropylene suture was threaded into the lumen of a custom bent 27-gauge needle, and the needle tip was advanced into the eye from the intraocular lens (IOL) fixation point. The suture was threaded through the posterior limbal incision inside the IOL haptic loop and pulled out.
