Objective: To evaluate the efficacy of pars plana vitrectomy (PPV) combined with internal limiting membrane (ILM) peeling in cases of ischemic central retinal vein occlusion (CRVO) where macular edema (ME) persisted after anti-vascular endothelial growth factor (anti-VEGF) treatment. Methods: Fifteen eyes with ischemic CRVO-related ME were included in the study. Nine were treated with panretinal photocoagulation after initial examination. Anti-VEGF agents were injected intravitreally. Persistent ME was treated with PPV combined with ILM peeling. During surgery, laser photocoagulation was further applied to the non-perfused area. Results: Mean retinal thickness gradually decreased after surgery (p = 0.024 at 6 months), although visual acuity did not improve significantly during the follow-up period (14.7 ± 11.6 months). Neovascular glaucoma subsequently developed in three cases and a trabeculectomy was performed in one case. Conclusion: In eyes with ischemic CRVO, PPV combined with ILM peeling contributed to a reduction in persistent ME. However, there was no significant improvement in visual acuity.

Tractional retinal detachment is an uncommon complication of intravitreal anti-vascular endothelial growth factor (VEGF) injection wherein the drug triggers tractional retinal detachment as a result of fibrovascular membrane contraction. We present a case of a 42-year-old hypertensive woman diagnosed with chronic central retinal vein occlusion on both eyes. The right eye had total retinal detachment and neovascular glaucoma, while the left eye had retinal neovascularisation. Panretinal photocoagulation and intravitreal anti-VEGF injection was started on the left eye. However, she was lost to follow-up. She returned 4 months later with extensive tractional retinal detachment involving the macula on the left eye. She subsequently underwent vitrectomy with endolaser and silicone oil tamponade on the left eye. The anti-VEGF ‘crunch’ results from regression of fibrovascular proliferation with a concurrent increase in fibrosis, resulting in worsening retinal traction. With the widespread use of anti-VEGF agents, ophthalmologists need to be aware of this vision-threatening complication.

Background/aimsClinical trials suggest anti-vascular endothelial growth factor is more effective than intravitreal dexamethasone as treatment for macular oedema secondary to branch retinal vein occlusion. This study asks if ‘real world’ data from a larger and more diverse population, followed for a longer period, also support this conclusion.MethodsData collected to support routine care at 27 NHS (National Health Service) Trusts between February 2002 and September 2017 contained 5661 treatment-naive patients with a single mode of treatment for macular oedema secondary to branch retinal vein occlusion and no history of cataract surgery either during or recently preceding the treatment. Number of treatment visits and change in visual acuity from baseline was plotted for three treatment groups (anti-vascular endothelial growth factor (anti-VEGF), intravitreal dexamethasone, macular laser) for up to 3 years.ResultsMean baseline visual acuity was 57.1/53.1/62.3 letters in the anti-VEGF/dexamethasone/macular laser groups, respectively. This changed to 66.72 (+9.6)/57.6 (+4.5)/63.2 (+0.9) at 12 months. Adequate numbers allowed analysis at 18 months for all groups (66.6 (+9.5)/56.1 (+3.0)/60.8 (-1.5)) and for anti-VEGF at 36 months (68.0, +10.9) Mean number of treatments were 5.1/1.5/1.2 at 12 months, 5.9/1.7/1.2 at 18 months for all three groups and 10.3 at 36 months for anti-VEGF.ConclusionsVisual acuity improvements were higher and more sustained with anti-VEGF. Higher treatment burden occurred with anti-VEGF but this reduced over 36 months. Patients with better vision at baseline than those in the clinical trials maintained high levels of vision with both anti-VEGF and dexamethasone.

Purpose: To report a case series, whereby we encountered a transient increase in retinal cotton wool spots (CWS) following anti-vascular endothelial growth factor (anti-VEGF) therapy for the treatment of macular edema secondary to central retinal vein occlusion (CRVO). Methods: Eighteen eyes were treated with intravitreal aflibercept (IVA), and 5 were treated with intravitreal ranibizumab (IVR). Fundus photographs obtained 1 month after initial IVA or IVR injections were retrospectively evaluated for the presence of CWS. Results: Twenty-one (91.3%) patients had the following systemic diseases: hypertension, diabetes mellitus without retinopathy, dyslipidemia, or chronic renal failure requiring dialysis. One month after treatment, reduced macular edema was observed in 21 (91.3%) eyes. Initial injections facilitated complete resolution in 14 eyes, and CWS gradually became fainter with additional injections. Conclusion: Some eyes with CRVO-related macular edema can show a transient increase in CWS after initial anti-VEGF therapy; however, macular edema, retinal hemorrhage, and visual acuity were improved in almost every case.
