Purpose: To evaluate the safety and efficacy of a novel approach to implant Ex-Press mini shunt via the pars plana under a scleral flap in pseudophakic or aphakic, vitrectomized patients with secondary refractory glaucoma. Methods: A prospective interventional case series of three patients with secondary glaucoma after pars plana vitrectomy. Intraocular pressure was not controlled by silicone oil removal, if the patient was siliconized, nor the maximum medical treatment. Ex-Press mini shunt via the pars plana was implanted. We evaluated the control of intraocular pressure and the development of intraoperative and postoperative complications. Results: During 1-year follow-up, control of intraocular pressure was achieved; 14, 15, and 15 mmHg at the 3 months, and 15, 15, and 16 mmHg at the 6 months in our three cases without antiglaucoma treatment and 16, 16, and 18 with single antiglaucoma medication at 1 year. Blebs were posterior and diffuse. No complications were encountered intraoperatively or postoperatively. Ultrasound biomicroscopy showed suprachoroidal posterior lake of fluid as an additional filtration route without any choroidal or retinal complication. Conclusion: Implantation of Ex-Press mini shunt via the pars plana in aphakic or pseudophakic, vitrectomized eyes is a promising, safe, and effective technique in patients with secondary glaucoma.

Secondary glaucoma may develop after vitreoretinal surgery as it is a known risk factor for its development. When the risk factors are more than one, for instance along with neovascular glaucoma (NVG), the secondary glaucoma may become recalcitrant and very difficult to manage. Surgical intervention is often warranted to control intraocular pressure (IOP) and prevent progressive glaucomatous damage in patients with refractory glaucoma, and glaucoma drainage implant may be preferred as the primary choice. We describe a patient who develop secondary glaucoma after vitrectomy and silicone oil (SO) injection due to unresolved vitreous hemorrhage in proliferative diabetic retinopathy (PDR) and subsequent NVG. Baerveldt glaucoma implant (BGI) was carried out and placed in the superotemporal quadrant with longer anterior chamber tube placement to prevent escape of SO through the tube. Qualified success was achieved with additional one fixed-drug combination (FDC). However, 3 years later, the tube was blocked by the iris tissue at the inferior edge of the pupil. Tube trimming was performed efficiently using a simple technique. The distal end of the tube was pulled out of the anterior chamber through a paracentesis just next to the tube entrance and trimmed to the appropriate length. More than a year after the surgery, IOP was still well controlled with the same FDC. Unfortunately, the visual acuity could not be recovered due to advanced PDR.

Anatomical Success

Purpose To evaluate the use of F6H8 as a temporary endotamponade for complicated and special cases of retinal detachment instead of silicone oil. Methods We have used F6H8 with 14 patients since February 1999. Eight suffered from rhegmatogenous retinal detachment (RRD) with multiple tears located inferiorly. Three presented inferior traction retinal detachment (TRD) under silicone oil, two suffered from ocular trauma with inferior TRD, and one had idiopathic macular hole. The substance was introduced into the eye after pars plana vitrectomy and membrane peeling if needed, and we tried to introduce as much as possible. Results With F6H8 the retina was easily reattached in all cases, like with perfluorocarbon liquids. The postoperative view was very good. F6H8 was removed in all cases after 3–8 weeks. Anatomical success was achieved in 12 out of 14 eyes. Two eyes presented severe PVR. F6H8 entered the anterior chamber in 4 cases, but no corneal complications occurred. In one case there was a marked IOP rise due to an anterior block, treated with superior iridotomy. In two cases retinal detachment (RD) occurred in the upper part and was treated with additional surgery, F6H8 removal and silicone oil injection. Conclusions F6H8 seems to be a promising tamponade agent for special cases of RD.

Open Globe Injuries

Purpose: To investigate the possible risk factors and prognosis of initial no light perception (NLP) in pediatric open globe injuries (POGI). Procedures: This retrospective, comparative, interventional case-control study included 865 eyes of POGI patients presenting to a tertiary referral ophthalmic center from 1 January 2011 to 31 December 2015. Eyes were divided into two groups: NLP group included eyes with initial NLP, and light perception(LP) group included eyes with initial LP or vision better than LP. Results: The following risk factors were significantly related to initial NLP: severe intraocular hemorrhage (OR=3.287, p=0.015), retinal detachment (RD) (OR=2.527, p=0.007), choroidal damage (OR=2.680, p=0.016) and endophthalmitis (OR=4.221, p＜0.001). Choroidal damage is related to remaining NLP after vitreoretinal surgery (OR=12.384, p=0.003). At the last visit, more eyes in the NLP group suffered from silicone oil–sustained status (OR=0.266, p=0.020) or ocular atrophy (OR=0.640, p=0.004), and less eyes benefitted from final LP (OR=41.061, p＜0.001) and anatomic success (OR=4.515, p＜0.001). Conclusion: Severe intraocular hemorrhage, RD, choroidal damage and endophthalmitis occurred more often in POGI with initial NLP. Choroidal damage was the major factor related to an NLP prognosis. Traumatized eyes with initial NLP could be anatomically and functionally preserved by vitreoretinal surgery.

PurposeTo analyse the functional and anatomical outcomes of different types of keratoprostheses in eyes with retained silicone oil following vitreoretinal surgery.MethodsRetrospective chart review of patients operated with any type of permanent keratoprosthesis (Kpro) in silicone oil-filled eyes between March 2003 and June 2017 were analysed.Results40 silicone oil-filled eyes underwent keratoprostheses, of which 22 were type 1 and 18 were type 2 Kpros (Lucia variant—nine, modified osteo odonto kerato prosthesis (MOOKP)—four, Boston type 2—three and osteoKpro—two) with a mean follow-up of 61.54 , 42.77, 45.25 , 25 and 37 months, respectively. Anatomic retention of the primary Kpro was noted in 33 eyes (82.5%). A best-corrected visual acuity of better than 20/200 and 20/400 was achieved in 26 (65%)+32 (80%) eyes. Retroprosthetic membrane (RPM) was the most common complication noted in 17 eyes (42.5%). Perioptic graft melt was noted in 4 of 22 eyes of the type 1 Kpro (2 (10.5%) without associated ocular surface disorder (OSD)) and in 1 eye each of Boston and Lucia type 2 Kpro. Laminar resorption occurred in one eye each of the MOOKP and OKP groups. Endophthalmitis and glaucoma did not occur in any eye.ConclusionAppropriately chosen keratoprosthesis is a viable option for visual rehabilitation in eyes post vitreoretinal surgery with retained silicone oil-induced keratopathy not amenable to conventional penetrating keratoplasty. Kpro melt among type 1 Kpro did not occur in 89.5% eyes without associated OSD (19 of 22 eyes), despite the lack of aqueous humour and presence of RPM (4 eyes), two factors considered to play a significant role in the causation of sterile melts. Of interest to note was the absence of infection in any of these eyes. The possible protective role of oil from endophthalmitis is interesting, though yet to be ascertained.
