| Abstract |
Neovascular age-related macular degeneration is the leading cause of vision loss in the elderly. We aimed to identify baseline predictors of visual prognosis after intravitreal conbercept injection for neovascular age-related macular degeneration. We conducted a retrospective review of 58 patients with neovascular age-related macular degeneration who were treated with intravitreal injections of conbercept 0.5 mg in routine clinical practice. Basic information such as age, sex, intraocular pressure, and disease course was collected. Best-corrected visual acuity, mean retinal sensitivity, and optical coherence tomography findings were recorded at baseline and 6 months after treatment. Logistic regression analysis was used to identify independent predictors of best-corrected visual acuity at 6 months after treatment. After the 6-month treatment, the mean best-corrected visual acuity improved from 1.10 ± 0.42 logarithm of the minimum angle of resolution (logMAR) to 0.41 ± 0.18 logMAR, the mean retinal sensitivity increased from 5.13 ± 0.86 dB to 7.32 ± 1.21 dB, the mean central retinal thickness decreased from 440.38 ± 61.05 μm to 260.01 ± 24.86 μm, and the total number of hyperreflective dots and the number of hyperreflective dots in each retina layer were significantly reduced as compared with those before treatment (all p<0.05). Twenty-two patients showed improved vision, and 36 had unimproved vision. Multivariate analyses revealed that the number of subretinal hyperreflective dots, the state of external limiting membrane, baseline best-corrected visual acuity, and age were independent predictors of best-corrected visual acuity (all p<0.05). Poor recovery of patients after intravitreal conbercept injection may be related to the number of subretinal hyperreflective dots, the state of external limiting membrane, baseline best-corrected visual acuity, and age, which may be used as predictors of short-term visual outcomes and should be fully evaluated before operation. |

Attention Score in Context
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 21 February 2022.
All research outputs
#17,301,727
of 25,392,582 outputs
Outputs from Arquivos Brasileiros de Oftalmologia
#155
of 445 outputs
Outputs of similar age
#270,798
of 475,273 outputs
Outputs of similar age from Arquivos Brasileiros de Oftalmologia
#2
of 17 outputs
Altmetric has tracked 25,392,582 research outputs across all sources so far. This one is in the 21st percentile – i.e., 21% of other outputs scored the same or lower than it.
So far Altmetric has tracked 445 research outputs from this source. They receive a mean Attention Score of 2.5. This one is in the 47th percentile – i.e., 47% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 475,273 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 29th percentile – i.e., 29% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 17 others from the same source and published within six weeks on either side of this one. This one has gotten more attention than average, scoring higher than 64% of its contemporaries.
