Macular Hemorrhage Due to Age-Related Macular Degeneration or Retinal Arterial Macroaneurysm: Predictive Factors of Surgical Outcome.

ABSTRACT:

Objective

The study aimed to determine the outcomes and prognostic factors of vitrectomy, subretinal injection of tissue-plasminogen activator and gas tamponade in macular hemorrhage (MaH) due to age-related macular degeneration (AMD) or retinal arterial macroaneurysm (RAM).

Methods

The study design utilized a multicentric retrospective case series design of consecutive patients undergoing surgery between 2014 and 2019.

Results

A total of 65 eyes from 65 patients were included in the study. Surgery was performed after a mean period of 7.1 days. Displacement of MaH was achieved in 82% of the eyes. Mean best-corrected visual acuity (BCVA) improved from 20/500 to 20/125 at month(M)1 and M6 (p < 0.05). At M6, BCVA worsening was associated with an older age at diagnosis (p = 0.0002) and higher subretinal OCT elevation of MaH (p = 0.03). The use of treat and extend (TE) (OR = 16.7, p = 0.001) and small MaH fundus size (OR = 0.64 and 0.74 for horizontal and vertical fundus size, p < 0.05) were predictive of a higher likelihood of obtaining a countable BCVA at M1. Baseline BCVA was predictive of postoperative BCVA (p < 0.05). Retinal detachment and MaH recurrence occurred in 3% and 9.3% of cases at M6.

Conclusion

MaH surgery stabilizes or improves BCVA in 85% of cases. Younger age at diagnosis, better baseline BCVA figures, smaller subretinal MaH height and use of TE regime were predictive of the best postoperative outcomes.

Project description:PURPOSE:To evaluate the association between use of antiplatelet or anticoagulant drugs and retinal or subretinal hemorrhage in participants with neovascular age-related macular degeneration (AMD) in the Comparison of AMD Treatments Trials (CATT). DESIGN:Cohort study within CATT. PARTICIPANTS:Participants in CATT with untreated active neovascular AMD (n = 1185). METHODS:Participants were interviewed for use of antiplatelet or anticoagulant drugs. Trained readers evaluated photographs for the presence and size of retinal or subretinal hemorrhage at baseline and years 1 and 2. Associations between use of antiplatelet or anticoagulant drugs and hemorrhage were evaluated among all participants and by baseline hypertension status using multivariate logistic regression models. MAIN OUTCOME MEASURES:Odds ratio for association with antiplatelet or anticoagulant use. RESULTS:Among 1165 participants with gradable photographs, 724 (62.1%) had retinal or subretinal hemorrhage at baseline; 84.4% of hemorrhages were 1 disc area (DA) or less, 8.1% were 1 to 2 DA, and 7.5% were more than 2 DA. At baseline, 608 participants (52.2%) used antiplatelet or anticoagulant drugs, including 514 participants (44.1%) using antiplatelets only, 77 (6.6%) using anticoagulants only, and 17 (1.5%) using both. Hemorrhage was present in 64.5% of antiplatelet or anticoagulant users and in 59.6% of nonusers (P = 0.09; adjusted odds ratio [OR], 1.18; 95% confidence interval, 0.91-1.51; P = 0.21). Neither presence nor size of baseline hemorrhage was associated with the type, dose, or duration of antiplatelet or anticoagulant use. Forty-four of 1078 participants (4.08%) had retinal or subretinal hemorrhage detected on 1- or 2-year photographs; these hemorrhages were not associated with antiplatelet or anticoagulant use at baseline (P = 0.28) or during follow-up (P = 0.64). Among participants with hypertension (n = 807), antiplatelet or anticoagulant use was associated with a higher rate of hemorrhage at baseline (66.8% vs. 56.4%; adjusted OR, 1.48; P = 0.01), but not size of retinal or subretinal hemorrhage (P = 0.41). CONCLUSIONS:Most retinal or subretinal hemorrhages in eyes enrolled in CATT were less than 1 DA. Among all CATT participants, antiplatelet or anticoagulant use was not associated significantly with hemorrhage, but it was associated significantly with hemorrhage in participants with hypertension.
