Unlabelled: We performed a prospective, randomized trial assessing the "remaining" volume of anesthetic solution that stays within the sub-Tenon's space after administration of 2 different volumes: 3 mL and 5 mL. The remaining volume correlated with motor block (r = 0.72; P < 0.001). The volume lost through the incision as a percentage of total volume injected was similar in both groups, suggesting sub-Tenon's space is not limited to a finite injected volume less than 5 mL and may be capable of receiving larger volumes of anesthetic to improve motor block.
Implications: The volume of anesthetic solution remaining within sub-Tenon's space correlates with motor block. The amount of volume lost as a percentage of total administered is independent of the volume injected, suggesting sub-Tenon's space is not limited to a finite injected volume less than 5 mL and may be capable of receiving larger volumes of anesthetic to improve motor block.

National Healthcare Group eye Institute, Tan Tock Seng Hospital, Singapore.
Purpose: To elucidate etiology and management of retropupillary sulcus migration of intravitreal gas after uneventful retinal detachment repair surgery.
Methods: 70 year old Caucasian man presented with a temporal macula-off rhegmatogenous retinal detachment. 25-gauge (25G) pars plana vitrectomy was performed with cryopexy to retinal tear and 12% C3F8 gas tamponade under sub-Tenon's anaesthesia.
Risk factors for failing sub-Tenon's triamcinolone acetonide for uveitic macular edema.

Background: Sub-Tenon's triamcinolone acetonide (STA) is less effective than intravitreal corticosteroids in the treatment of uveitic macular edema (ME), but does have some relative advantages, including substantially lower cost and decreased risk of post-injection ocular hypertension. It would be useful for clinicians to know which eyes may respond well to STA and not necessarily require intravitreal therapy. The objective of this study is to identify risk factors for failing STA for the treatment of uveitic ME.

The surface area of encapsulation around the Ahmed glaucoma valve (AGV) endplate is a critical factor in the surgical outcome as it is associated with the degree of IOP reduction. We investigated the surgical outcome of AGV implantation with an additional pericardium graft inserted adjacent to the endplate, with the intent of expanding the surface area of encapsulation. We enrolled 92 patients (92 eyes) who underwent AGV implantation.

Aim: We report a case of successful intraocular pressure (IOP) management in a patient with refractory primary open-angle glaucoma (POAG) following implantation of XEN gel implant in the same hemisphere as prior failed filtering surgeries [i.e., Baerveldt glaucoma implant (BGI) and trabeculectomy bleb)].

The surgical management of glaucoma has been revolutionized by the introduction of minimally invasive glaucoma surgery (MIGS). The various MIGS options aim to meaningfully lower intraocular pressure with a better safety profile than traditional glaucoma surgery. The key clinical attributes and the emerging potential of an ab externo MicroShunt (PreserFlo™) are reviewed in the context of published evidence and clinical experience.
