Gravitational displacement of submacular haemorrhage in patients with age-related macular disease.

ABSTRACT:

Objectives

To investigate the efficacy of gravitational displacement following vitrectomy for the patients with submacular haemorrhage (SMH) secondary to age-related macular degeneration (AMD).

Methods

Retrospective, interventional series of nine consecutive AMD patients with SMH. All patients underwent pars plana vitrectomy (PPV) combined with subretinal tissue plasminogen activator (t-PA) and intravitreal anti-vascular endothelial growth factor (anti-VEGF) injection without any tamponade. The patients were positioned according to the location and distribution of SMH postoperatively in order to provide the maximum gravitational force effect to displace. Outcome measures were the change in visual acuity, the displacement in SMH, and the occurrence of per- and postoperative complications.

Results

Complete displacement of haemorrhage occurred in all patients postoperatively. The mean preoperative and postoperative best-corrected visual acuity (BCVA) at the last visit were 2.46 and 1.7 logMAR, respectively, after a mean follow-up of 10.4 months (Range: 3-18 months) (p = 0.045). The mean duration of haemorrhage was 15.3 days (range: 3-40 days). The recurrence of SMH was observed in two (22%) patients and there were no other postoperative complications.

Conclusion

Gravitational displacement following PPV combined with subretinal t-PA and intravitreal anti-VEGF injection can be considered as an effective surgical intervention in selected AMD patients with SMH.

Project description:PurposeTo investigate the clinical features, treatment options, and visual outcomes of submacular hemorrhage (SMH) secondary to neovascular age-related macular degeneration (nAMD).DesignA retrospective, observational case series.MethodsSetting: Multicenter institutional setting. Patient Population: A total of 127 patients (127 eyes; 88 men, 39 women; (mean age, 74.2 years)) diagnosed with AMD-associated SMHs exceeding 2 disc diameters involving the fovea. Observation: The AMD types, previous treatments, treatment options, anatomic findings, and best-corrected visual acuity (BCVA) were assessed. Main Outcome Measures: Clinical features, treatment options, and visual outcomes of SMHs secondary to nAMD.ResultsThirty-two eyes had typical AMD, 94 eyes polypoidal choroidal vasculopathy (PCV), and one eye retinal angiomatous proliferation. Eighty-five eyes were treatment-naïve; 42 eyes were treated previously: anti-vascular endothelial growth factor (VEGF) therapy (n = 26), photodynamic therapy (n = 3), and combined therapy (n = 13). Treatment of SMHs included vitrectomy (36 eyes), pneumatic displacement (49 eyes), and anti-VEGF monotherapy (42 eyes). The final BCVA improved significantly in treatment-naïve cases from 0.86 to 0.62 logarithm of the minimal angle of resolution (logMAR) unit (Snellen equivalent from 20/145 to 20/83) and from 0.80 to 0.56 (Snellen equivalent from 20/126 to 20/73) in PCV cases. Meanwhile, the BCVA logMAR values improved from 1.15 to 0.75 (Snellen equivalent from 20/283 to 20/112) and from 0.87 to 0.63 (Snellen equivalent from 20/148 to 20/85) in eyes that underwent vitrectomy or pneumatic displacement, respectively. In eyes with BCVAs between 20/133 to 20/40 at SMH onset, the final VA in the pneumatic displacement group was better than in the anti-VEGF monotherapy group. One eye had a retinal detachment and 1 eye had a macular hole in the vitrectomy group, and 5 eyes had a vitreous hemorrhage in the pneumatic displacement group.ConclusionsThe recommended treatment for SMHs secondary to nAMD exceeding 2 disc area and with BCVA below 20/40 is vitrectomy or pneumatic displacement for visual improvement.

Project description:PurposeTo report the natural history of untreated neovascular age-related macular degeneration (nAMD) regarding subsequent macular atrophy.DesignProspective cohort within a randomized, controlled trial of oral micronutrient supplements.ParticipantsAge-Related Eye Disease Study (AREDS) participants (55-80 years) who demonstrated nAMD during follow-up (1992-2005), prior to anti-vascular endothelial growth factor (VEGF) therapy.MethodsColor fundus photographs were collected at annual study visits and graded centrally for late age-related macular degeneration (AMD). Incident macular atrophy after nAMD was examined by Kaplan-Meier analysis and proportional hazards regression.Main outcome measuresIncident macular atrophy after nAMD.ResultsOf the 4757 AREDS participants, 708 eyes (627 participants) demonstrated nAMD during follow-up and were eligible. The cumulative risks of incident macular atrophy after untreated nAMD were 9.6% (standard error, 1.2%), 31.4% (standard error, 2.2%), 43.1% (standard error, 2.6%), and 61.5% (standard error, 4.3%) at 2, 5, 7, and 10 years, respectively. This corresponded to a linear risk of 6.5% per year. The cumulative risk of central involvement was 30.4% (standard error, 3.2%), 43.4% (standard error, 3.8%), and 57.0% (standard error, 4.8%) at first appearance of atrophy, 2 years, and 5 years, respectively. Geographic atrophy (GA) in the fellow eye was associated with increased risk of macular atrophy (hazard ratio [HR], 1.70; 95% confidence interval [CI], 1.17-2.49; P = 0.006). However, higher 52-single nucleotide polymorphism AMD genetic risk score was not associated with increased risk of macular atrophy (HR, 1.03; 95% CI, 0.90-1.17; P = 0.67). Similarly, no significant differences were observed according to SNPs at CFH, ARMS2, or C3.ConclusionsThe rate of incident macular atrophy after untreated nAMD is relatively high, increasing linearly over time and affecting half of eyes by 8 years. Hence, factors other than anti-VEGF therapy are involved in atrophy development, including natural progression to GA. Comparison with studies of treated nAMD suggests it may not be necessary to invoke a large effect of anti-VEGF therapy on inciting macular atrophy, although a contribution remains possible. Central involvement is present in one third of eyes at the outset (similar to pure GA) and increases linearly to half at 3 years.
