A 72-year-old Japanese woman presented to our hospital with decreased vision. At the initial visit, her best-corrected visual acuity (BCVA) and intraocular pressure (IOP) in her right eye (OD) were 0.02 and 36 mm Hg, respectively. By slit lamp examination, rubeosis iridis was observed on the iris surface. With higher magnification observation, movement of clustered RBCs were clearly observed; the blood drained into episcleral vessels that were connected with the main trunk of rubeosis iridis. She was diagnosed with the neovascular glaucoma secondary to central retinal vein occlusion OD. She underwent panretinal photocoagulation, intravitreal injection of aflibercept, and Ahmed Glaucoma Valve implantation. At 2 weeks postoperatively, the BCVA and IOP OD were 0.2 and 7 mm Hg, respectively; rubeosis iridis was partially regressed and movement of RBCs was not observed. Acquisition of directional flow by the connection of the main trunk of neovessels with the episcleral vessels and reduction of flow speed by the high IOP could explain the reason for visible blood flow in our case.

Valve Implantation

AIM: To describe and evaluate the efficacy of Ahmed glaucoma valve implantation (AGV) combined with pars plana vitrectomy (PPV) in a single surgical act for the treatment of advanced neovascular glaucoma (NVG). METHODS: Retrospective observational case series included 51 eyes from 50 patients with severe NVG treated with PPV, AGV, and panretinal photocoagulation and/or cryotherapy in a single surgical act during a 13-year period (2005-2018). Preoperative, intraoperative and postoperative data at day 1 and months 1, 3, 6, 21, and 24 were systematically collected. Definition of surgical success was stablished at IOP between 6 and 21 mm Hg with or without topical treatment. RESULTS: Main indications for surgery were NVG secondary to proliferative diabetic retinopathy (39.2%) and central retinal vein occlusion (37.3%). Mean (±SD) preoperative IOP was 42.0±11.2 mm Hg decreasing to 15.5±7.1 mm Hg at 12mo and 15.8±9.1 mm Hg at 24mo of follow up. Cumulative incidence of success of IOP control was 76.0% at first postoperative month, reaching 88.3% at 6mo. Prevalence of successful IOP control at long term was 74.4% at 12mo and 71.4% at 24mo. Eye evisceration for unsuccessful NVG management was required in 1 case (2.0%). CONCLUSION: Combination of AGV implantation and PPV in a single act may be a suitable option for severe forms of NVG in a case-by-case basis for effective IOP control and a complete panretinal photocoagulation.

Objective: To investigate intravitreal aflibercept (IVA) injection as an adjunctive treatment to trabeculectomy with mitomycin C (TMC) and panretinal photocoagulation (PRP) for neovascular glaucoma (NVG).Materials and Methods: PRP and IVA (2 mg/0.05 ml) injection were given, and TMC was performed within 2weeks after IVA. Additional PRP, laser suture lysis, subconjunctival 5-fluorouracil injection, and bleb needlingwere performed after TMC if indicated. Best corrected visual acuity (BCVA), intraocular pressure (IOP), surgicalcomplications, and number of anti-glaucoma medications were collected.Results: Five eyes from 5 consecutive patients were included. Two eyes had proliferative diabetic retinopathy (PDR), 2 central retinal vein occlusion, and 1 ocular ischemic syndrome (OIS) (mean initial IOP: 46.8±6.8 mmHg). NVI regression occurred in one eye after PRP alone, and in one eye after PRP and IVA resulting in a good IOP control with topical medical therapy. The other 3 underwent TMC. The preoperative IOP was 34 (OIS), 54 (PDR), and 50 (PDR) mmHg. The 3-month postoperative IOP decreased to 8, 8, and 4 mmHg, respectively, and to 21, 10, and 6 mmHg, respectively, at the last visit. Only the one OIS eye required postoperative topical IOP-lowering medications. Final BCVA was improved, unchanged, and decreased in 2, 2, and 1 eye, respectively. No intraoperative/postoperative complications or NVI recurrence were observed (mean follow-up: 10.7 months).Conclusion: Intravitreal aflibercept was shown to be a potentially effective additional treatment to PRP and TMC in patients with NVG.

A 61-year-old Japanese woman presented with impairment of her left vision due to macular schisis secondary to branch retinal vein occlusion. Her left vision was 20/50, and schisis was observed inferotemporally. She underwent phacoemulsification and aspiration, implantation of the intraocular lens, and removal of the epiretinal membrane and internal limiting membrane. Her visual acuity stabilized ~20/50 for two and a half years after the initial surgery. However, she developed macula-involving retinal detachment, and her visual acuity declined to counting fingers. She underwent pars plana vitrectomy and removal of the residual vitreous cortex together with the inner retina within the area of vein occlusion. After the removal of silicone oil and the addition of an encircling buckle, the retina remained attached and visual acuity improved to 20/60 at one year after the final surgery. The combination of rhegmatogenous and tractional detachment in the area of schisis was suspected, and vitrectomy with inner retinectomy was effective.

Treatment Paradigm

We review articles describing intravitreal injection of anti-VEGF drug trials, while discussing the mechanisms of the action of anti-VEGF antibodies, and also evaluating their outcomes. Intraocular injections of anti-VEGF drug are considered to be an effective treatment for macular edema after retinal vein occlusion, however, recurrent/persistent edema is common. The recent reports may lead to a shift in treatment paradigm for DME, from laser photocoagulation, to newer approaches using anti-VEGF drugs. There have been several well-publicized prospective, randomized studies that demonstrated the efficacy of intravitreal injection of anti-VEGF drugs for patients with AMD. Adjuvant bevacizumab for neovascular glaucoma may prevent further PAS formation, and it is likely to open up a therapeutic window for a panretinal photocoagulation and trabeculectomy. Intravitreal injection of bevacizumab (IVB) results in a substantial decrease in bleeding from the retinal vessels or new vessels during a standard vitrectomy. IVB has also been reported to be effective for inducing the regression of new vessels in proliferative diabetic retinopathy. The use of bevacizumab in stage 4 or 5 retinopahty of permaturity (ROP) is to reduce the plus sign to help reduce hemorrhage during the subsequent vitrectomy. Some authors reported cases of resolution of stage 4 A ROP after bevacizumab injection.

Abstract Background Takotsubo syndrome is a sudden and an acute form of transient cardiac dysfunction, triggered by mental and physical stress. The treatment for Takotsubo syndrome is not well understood and is incompletely established. Takotsubo syndrome is partly thought to be caused by coronary ischemia under sympathetic nerve activation. Case presentation We report the case of an 80-year-old Japanese woman with recurrent Takotsubo syndrome complicated with ischemic enteritis. In this case, abdominal pain and dehydration due to ischemic enteritis is thought to have triggered Takotsubo syndrome. Her life was saved with rapid, adequate intravenous hydration. She was diagnosed with coronary vasospastic angina using coronary angiography on her second admission. This case highlights the potential of adequate intravenous hydration in increasing coronary blood flow. In our case, it should be noted that pulmonary congestion was mild and may have improved Takotsubo syndrome without the use of diuretics. Conclusion Adequate hydration must be considered for prompt improvement of cardiac function in Takotsubo syndrome. Replenishment of fluid to increase coronary blood flow, improvement of heart load without exacerbating heart failure, and stabilization of circulation dynamics can help treat patients with Takotsubo syndrome without using diuretics.
