PURPOSE: To describe the feasibility and efficacy of performing single-pass four-throw pupilloplasty for secondary angle-closure glaucoma post silicon oil tamponade. METHODS: The procedure was performed in five eyes of five patients. All the cases underwent silicon oil removal with single-pass four-throw pupilloplasty. Single-pass four-throw procedure involves a single pass of needle through the iris tissue that is to be apposed followed by taking four throws by passing the suture end through the loop that is withdrawn from the anterior chamber as in a modified Siepser's slip-knot technique...

Purpose: To evaluate the outcomes of Ahmed glaucoma valve (AGV) implantation in vitrectomized eyes. Materials and Methods: The medical records of 13 eyes that developed glaucoma due to emulsified silicon oil or neovascularization following pars plana vitrectomy and underwent AGV implantation were retrospectively reviewed. The main outcome measures were intraocular pressure (IOP), best-corrected visual acuity (BCVA), number of antiglaucoma medications, and postoperative complications...

METHODS: A chart review was conducted at St. Michael's Hospital and The Hospital for Sick Children (Toronto, Canada), where the patient received ophthalmic care from July 28, 2015 onwards. RESULTS: A 14-year-old boy with a history of traumatic retinal detachment and proliferative vitreoretinopathy in the left eye, requiring 2 pars plana vitrectomies, membrane peel, and SO tamponade, presented with 1-day history of decreased vision in the left eye, severe headache, nausea, and vomiting...

PURPOSE: To demonstrate the presence of emulsified silicone oil (SO) droplets in the canal of Schlemm with anterior segment optical coherence tomography (AS-OCT). METHODS: AS-OCT images from an eye that had undergone retinal detachment (RD) surgery three years ago were reviewed. At the time of surgery, SO had been used as the tamponading agent. RESULTS: The AS-OCT images demonstrated that minute emulsified SO droplets were present in the canal of Schlemm...

Ocular bee stings are known to cause corneal melts, corneal infiltrates, cataracts, and secondary glaucoma. Our patient presented with scleritis, corneal infiltrates, and endophthalmitis after a ocular bee sting. Topical treatment led to resolution of anterior segment inflammation, but the scleritis and vitreous inflammation worsened. Vitrectomy with intravitreal antibiotics was done and scrapings from the scleral abscess showed growth of Aspergillus fumigatus on culture. Repeat vitrectomy with silicone oil was needed for retinal detachment...

Zhen Liu, Gang Fu, Aihua Liu
The expression of inflammatory mediators in the aqueous humor and the incidence of secondary glaucoma after vitreous body resection combined with silicone oil tamponade for patients with retinal detachment were inestigated, and the roles of IL-17, IL-6 and TNF-α in secondary glaucoma after silicone oil tamponade were analyzed. Fifty-eight cases of retinal detachment treated by vitrectomy combined with silicone oil tamponade were examined at the time of silicone oil removal surgery. All patients underwent unilateral surgery...

David Fleischman, Bryan Kim
Surgical management of elevated intraocular pressure (IOP) in an eye with scarred conjunctiva, an encircling band, and silicone oil has limited options. By combining the flow restrictor of the Ahmed Glaucoma Valve (New World Medical, Rancho Cucamonga, California) and the capsule of the encircling band as a conduit for aqueous flow, immediate pressure reduction could theoretically be achieved in eyes with limited conjunctival mobilization. This is a description of a surgical technique in a case of a patient with multiple ocular surgeries with uncontrolled multimechanism glaucoma despite using all available topical and oral glaucoma medications...

PURPOSE: The purpose of the study is to describe a novel technique to implant Ahmed valves in patients with refractory glaucoma because of silicone oil (SO) endotamponade PATIENTS:: Three patients with glaucoma without SO removal were used as an example for this technique. METHODS: Technique report. RESULTS AND CONCLUSIONS: We introduce a standard technique modification for Ahmed valves in patients with SO. This modification consists on locating the Ahmed valve more tangential to the limbus curvature instead of the usual perpendicular position and inserting the tube in the posterior chamber...

Marco Codenotti, Lorenzo Iuliano, Gisella Maestranzi
Technical advancements have substantially extended the indications for surgery in diabetic retinopathy (DR) during the last 40 years, from the traditional indications including non-clearing vitreous hemorrhage, traction retinal detachment (RD), and traction-rhegmatogenous RD, to epiretinal membrane (ERM), vitreomacular traction, diffuse macular edema, neovascular glaucoma, and anterior hyaloid fibrovascular proliferation. The goals of vitreoretinal surgery in DR are multiple: clearing media opacities, release of traction (anteroposterior and/or tangential), segmentation and/or removal of traction bands, peeling of ERMs, hemostasis, laser photocoagulation, and tamponade of retinal breaks with gas or silicone oil...

REVIEW
I Lanzl, K Kotliar
An increasing number of patients receive intravitreal anti-vascular endothelial growth factor (anti-VEGF) injections with a high frequency for the treatment of neovascular macular disease. Since the volume of the vitreous body is temporarily increased by the injection of the substances, a short-term intraocular pressure increase after the introduction of the substance is not uncommon. However, there are more and more reports indicating that multiple injections may lead to a long-term increase in intraocular pressure...

OBJECTIVE The use of Gamma Knife radiosurgery (GKRS) as monotherapy in the treatment of uveal melanoma (UM) allows clinicians to achieve high local tumor control with low recurrence but does not prevent secondary enucleation due to glaucoma in cases of large tumors. The authors analyzed indications for tumor endoresection (ER), the time interval between irradiation and surgery, and the features and results of performing ER for UM after GKRS. METHODS Thirty-seven patients between 28 and 78 years of age (16 male and 11 female patients) with UM underwent GKRS with a dose of 70 to 80 Gy that was applied to the center of the tumor with complete immobilization of the eye during the procedure...
