Longitudinal renal function changes during real-world anti-vascular endothelial growth factor therapy for diabetic macular edema in Japan.
Observational study in Japanese journal of ophthalmology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled it.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeThis retrospective observational study aimed to investigate the longitudinal changes in renal function and central macular thickness (CMT) and their impact on visual outcomes during anti-vascular endothelial growth factor (anti-VEGF) therapy for diabetic macular edema (DME). STUDY
designThis study employed a retrospective observational design and analyzed data from treatment-naive patients with DME (62 cases, 100 eyes) receiving anti-VEGF therapy for 36 months. Baseline and follow-up assessments were conducted at 12, 24, and 36 months.
methodsBest corrected visual acuity (BCVA), CMT, number of anti-VEGF injections, HbA1c, serum creatinine (Cre), blood urea nitrogen (BUN), estimated glomerular filtration rate (eGFR), urinary protein levels, and chronic kidney disease (CKD) stage were measured at each time point.
resultsThe study population had a mean age of 60.7 ± 12.2 years, with 41 men and 21 women. Over the 36-month period, the mean number of anti-VEGF injections per eye was 5.3 ± 3.3. Maximum CMT significantly decreased at each time point, and final BCVA showed significant improvement (logMAR: - 0.07). HbA1c levels remained stable, BUN and Cre levels increased, and eGFR decreased significantly over time. CKD stage 3+ at 36 months significantly resulted in worse CMT.
conclusionThis retrospective observational study provides valuable insights into the longitudinal changes in renal function and CMT during anti-VEGF therapy for DME. Our findings emphasize the importance of monitoring renal function. This study contributes to our understanding of the complex relationship between renal function, DME, and anti-VEGF therapy, thereby facilitating improved management and outcomes in patients with DME.
