This report describes a series of cases with massive subretinal hemorrhage (SRH) due to age-related macular degeneration (AMD) treated by subretinal alteplase injections. In all cases, the surgical technique consisted in 25-gauge pars plana vitrectomy (PPV) and alteplase injection under the retina using a 38-gauge cannula. After the fluid-gas exchange, bevacizumab injection was performed in all patients. Three cases of SRH in which this technique was used, as well as their evolution at one week and one month postoperatively are described. Visual acuity was hand motion in all three cases at presentation. After surgery, a significant anatomical and functional improvement was noted in all cases. One month postoperatively, none of the patients had blood under the macula, and visual acuities significantly improved to 0.8, 0.2 and 0.16 (decimal fraction). A consistent reduction of central retinal thickness was observed on optical coherence tomography (OCT) from the first week postoperatively. No intra and postoperative complications were noted. Subretinal alteplase injection proved as a viable solution in these severe SRH with early presentation. There was no need to change the systemic anticoagulant and antiaggregant therapy. Bevacizumab intravitreal injection at the end of surgery has an important role in preventing further bleeding.
Submacular hemorrhage in neovascular age-related macular degeneration: A synthesis of the literature
Survey of ophthalmology, 2015
Large submacular hemorrhage, an uncommon manifestation of neovascular age-related macular degeneration, may also occur with idiopathic polypoidal choroidal vasculopathy. Submacular hemorrhage damages photoreceptors owing to iron toxicity, fibrin meshwork contraction, and reduced nutrient flux, with subsequent macular scarring. Clinical and experimental studies support prompt treatment, as tissue damage can occur within 24 hours. Without treatment the natural history is poor, with a mean final visual acuity (VA) of 20/1600. Reported treatments include retinal pigment epithelial patch, macular translocation, pneumatic displacement, intravitreal or subretinal tissue plasminogen activator, intravitreal anti-vascular endothelial growth factor (VEGF) drugs, and combinations thereof. In the absence of comparative studies, we combined eligible studies to assess the VA change before and after each treatment option. The greatest improvement occurred after combined pars plana vitrectomy, subre...
Surgical Outcomes After Massive Subretinal Hemorrhage Secondary to Age-Related Macular Degeneration
Retina-the Journal of Retinal and Vitreous Diseases, 2010
Purpose: Massive subretinal hemorrhage (SRH), defined as a thick submacular bleed that extends past the equator in at least two quadrants, is a rare sequela of age-related macular degeneration. This report describes outcomes after surgical intervention for massive SRH. Methods: The study design is a retrospective interventional case series. Records of consecutive patients who underwent surgical intervention for massive SRH were reviewed. Outcomes included change from baseline in postoperative acuity at Months 1, 3, 6, 9, and 12 and postoperative complications. Results: Fifteen consecutive eyes of 13 patients who underwent surgery for massive SRH were included. Procedures performed on initial surgery included subretinal instillation of 25 mg/0.1 mL tissue plasminogen activator (15 of 15), gas tamponade (12 of 15), oil tamponade (3 of 15), 180°or greater retinotomy (4 of 15), and/or cataract extraction (2 of 15). Patients were followed for a median of 20 months (range, 3-66 months). The median visual acuity at baseline and postoperative Month 1 was hand motions but improved to counting fingers at postoperative Months 3 (P = 0.04), 6 (P = 0.04), 9 (P = 0.04), and 12 (P = 0.10). Of the 15 eyes, 9 required at least 1 additional procedure for an indication of hyphema and/or vitreous hemorrhage (n = 6), retinal detachment (n = 2), glaucoma (n = 1), cataract (n = 1), and aphakia (n = 1). At the time of the onset of SRH, 5 of 13 patients were anticoagulated with warfarin (4 patients) or clopidogrel (1 patient), and 1 was diagnosed with a coagulopathy, factor XI deficiency. Conclusion: Massive SRH related to age-related macular degeneration has a grave prognosis. Risk factors may include anticoagulation and coagulopathy. Limitations of the study include its retrospective nature, small sample size, imprecision in acuity measurements below 20/400, and lack of a control group. In this series, surgical intervention was associated with a modest improvement in median visual acuity up to 1 year postoperatively.

To analyse the efficacy of subretinal injection of recombinant tissue plasminogen activator (rtPA) and gas tamponade for the displacement of submacular haemorrhage (SMH). Methods: This single-centre, retrospective, case series included 25 consecutive patients (25 eyes) who underwent pars plana vitrectomy (PPV) with subretinal rtPA injection and 20% sulphur hexafluoride (SF6) tamponade. The primary outcome was SMH displacement rate, defined as the absence of subretinal blood within (complete) or outside (partial) 1500 μm centred on the fovea one month after PPV. Secondary outcomes were final best-corrected visual acuity (BCVA), central macular thickness (CMT), recurrence probability, number of anti-vascular endothelial growth factor (VEGF) injections after PPV, and intra-and postoperative complications. Results: Successful displacement was obtained in all 25 eyes (100%), with complete and partial displacement obtained in 15 (60%) and 10 (40%), respectively. BCVA significantly improved from 1.81±0.33 to 1.37±0.52 LogMar at 12 months from surgery (p = 0.001). The bivariate correlation analysis revealed that earlier the surgery had better visual prognosis at the end of the follow-up (p = 0.007). CMT significantly decreased from 922 ± 273.69 µm at baseline to 403.53 ± 314.64 µm at 12 months follow-up (p < 0.001). SMH recurrence was observed in two (8%) patients with a mean survival time of 11.6 ± 0.339 months and a cumulative survival probability of 88% at the end of follow-up. After PPV, the mean number of anti-VEGF injections was 3.00 ± 0.957 with no correlation with final visual acuity (p = 0.365). No intraoperative complications were recorded. Only one patient developed open funnel retinal detachment 40 days after primary PPV. Conclusion: PPV with rtPA subretinal injection and SF6 tamponade is a safe and effective technique in displacing acute SMHs secondary to neovascular AMD. It is recommended to perform within 14 days from the onset of the symptoms to achieve BCVA improvement at 12 months and proper imaging to plan future anti-VEG treatment.

This paper aims to compare the effects of three treatment modalities for a submacular hemorrhage (SMH) secondary to exudative age-related macular degeneration (AMD). Seventy-seven patients with an SMH were divided into three groups: small-sized (optic disc diameter (ODD) ≥ 1 to < 4), medium-sized (ODD ≥ 4 within the temporal arcade) and large-sized (ODD ≥ 4, exceeding the temporal arcade). Patients received anti-vascular endothelial growth factor (anti-VEGF) monotherapy, pneumatic displacement (PD) with anti-VEGF or a vitrectomy with a subretinal tissue plasminogen activator (tPA) and gas tamponade based on the surgeon's discretion. The functional and anatomical outcomes were evaluated. Among the 77 eyes, 45 eyes had a small-sized, 21 eyes had a medium-sized and 11 eyes had a large-sized SMH. In the small-sized group, all treatment modalities showed a gradual best-corrected visual acuity (BCVA) improvement with high hemorrhagic regression or displacement rates (over 75%). In the medium-sized group, PD and surgery were associated with better BCVA with more displacement than anti-VEGF monotherapy (67% and 83%, respectively, vs. 33%). In the large-sized group, surgery showed a better visual improvement with a higher displacement rate than PD (86% vs. 25%). Our findings demonstrated that visual improvement can be expected through appropriate treatment strategy regardless of the SMH size. In cases with a larger SMH, invasive techniques including PD or surgery were more advantageous than anti-VEGF monotherapy.
Vitreous Surgery for Hemorrhagic and Fibrous Complications of Age-Related Macular Degeneration
American Journal of Ophthalmology, 1988
We applied vitreous surgical techniques in the treatment of hemorrhagic and fibrous com plications of choroidal neovascular mem branes by removing subretinal scars or hemor rhage, or both, in four patients. The surgical goals were achieved in all patients. Visual acuity improved in three patients. The major complication was recurrent detachment associ ated with large retinotomies. AGE-RELATED MACULAR DEGENERATION is the major cause of blindness in persons over 55 years of age. 1 Recently, argon laser photocoagulation has been shown to be effective in pre venting visual loss in a subgroup of patients with extrafoveal choroidal neovascular mem branes. 2 However, these results have been tem pered by a high recurrence rate 3 and a large proportion of eyes that do not meet criteria for treatment. 4 There are many patients who have suffered severe visual loss from the complica tions of macular degeneration. These complica tions include large serous retinal detachment (senile Coats' syndrome), subretinal hemor rhage, disciform scar formation, and break through vitreous hemorrhage. 57 Vitreous hemorrhage is an infrequent but well-known complication of age-related macu lar degeneration. 8 Vitreous surgery has been used to remove the hemorrhage from the vitre ous cavity and thus improve vision. 8 We used vitreous surgical techniques to treat other com plications of age-related macular degeneration,
