Critical analysis of techniques and materials used in devices, syringes, and needles used for intravitreal injections

• Syringes should have as little silicone oil as possible or none at all.
• Drug in the vial or the syringe should never be agitated
• New devices might play a role in assisting with intravitreal injection.
• Materials and techniques might cause complications when used inappropriately.
• The choice of the anesthetic technique is important for better patient comfort.

Non-contact wide-angled visualization with chandelier-assisted scleral buckling for primary uncomplicated rhegmatogenous retinal detachment

• Non-contact wide-angled visualization with chandelier-assisted scleral buckling compares favorably with conventional scleral buckling for primary uncomplicated primary RRD
• The main advantage is the improved visualization even through small pupils
• Better visualization avoid excessive treatment and ensures safer placement of intrascleral sutures for scleral fixation
• The improved visualization and magnification lends an enhanced platform for teaching aspiring vitreoretinal surgeons.
