Aim: To observe the therapeutic effect of conbercept on diabetic macular edema (DME) complicated with diabetic nephropathy (DN).
Methods: In this retrospective study, 54 patients (54 eyes) that diagnosed as DME from January 2017 to October 2021 were collected. The patients were divided into two groups: DME patients with DN (25 eyes), and DME patients without DN (29 eyes). General conditions were collected before treatment, laboratory tests include fasting blood glucose, HbA1c, microalbumin/creatinine, serum creatinine. Optical coherence tomography (OCT) was used to check the ellipsoidal zone (EZ) and external limiting membrane (ELM) integrity. Central macular thickness (CMT), best corrected visual acuity (BCVA), and retinal hyperreflective foci (HF) as well as numbers of injections were recorded.
Results: There were significant differences between fasting blood glucose, HbA1c, serum creatinine, urinary microalbumin/creatinine, and estimated glomerular filtration rate (eGFR) between the two groups (all <0.05). EZ and ELM continuity in the DME+DN group was worse than that in the DME group (<0.05). BCVA (logMAR) in the DME group was significantly better than that in the DME+DN group at the same time points during treatment (all <0.05). CMT and HF values were significantly higher in the DME+DN group than that in the DME group at the all time points (all <0.05) and significantly decreased in both groups with time during treatment. At 6mo after treatment, the mean number of injections in the DME+DN and DME group was 4.84±0.94 and 3.79±0.86, respectively.
Conclusion: Conbercept has a significant effect in short-term treatment of DME patients with or without DN, and can significantly ameliorate BCVA, CMT and the number of HF, treatment efficacy of DME patients without DN is better than that of DME patients with DN.

Analysis of macular retinal thickness in polyarteritis nodosa using spectral domain optical coherence tomography.
J Ophthalmic Inflamm Infect
January 2025
School of Medicine, National Taiwan University, Taipei, Taiwan.
Purpose: To identify the macular retinal layer thickness changes in polyarteritis nodosa (PAN) patients without pathological findings appearing in color fundus photography (CFP), and to investigate the correlations with disease durations.
Methods: A total of 24 PAN patients who had been for 3 years or more and underwent SD-OCT were recruited from the UK Biobank, with exclusions for diabetes, eye disease, or abnormal CFP findings. Only the right eyes were included, with each PAN patient paired one-to-one with a control matched for age, sex, and ethnicity.
Vitritis following intravitreal faricimab: a retrospective monocentric analysis.
Graefes Arch Clin Exp Ophthalmol
January 2025
15-20 National Ophthalmologic Center, Paris, France.
Purpose: Intravitreal injections of anti-VEGF agents are considered as safe, with a very low rate of intraocular inflammations (IOI). Faricimab is a novel intravitreal bispecific antibody targeting both VEGF-A and angiopoietin-Tie2 independently. Despite a safe profile in randomized clinical trials, several real-life studies have reported cases of IOI.

Department of Ophthalmology and Visual Sciences, Escola Paulista de Medicina, Universidade Federal de São Paulo, São Paulo, SP, Brazil.
Purpose: To evaluate the efficacy and safety of intense pulsed light (IPL) combined with meibomian gland expression (MGX) for the treatment of dry eye disease and meibomian gland dysfunction associated with chronic Stevens-Johnson syndrome and toxic epidermal necrolysis.
Methods: This prospective noncomparative interventional study included 29 patients (58 eyes) who underwent 3 sessions of IPL and MGX at 2-week intervals. Subjective symptoms (ocular surface disease index score) and objective dry eye tests: matrix metalloproteinase 9, tear meniscus height, bulbar redness score, tear film lipid layer thickness (LLT), Schirmer I test, conjunctival and corneal staining, meibomian gland loss, MGX score [meibomian gland score (MGS)], and tear break-up time were assessed at the baseline and after 4, 8, and 12 weeks.

Department of Ophthalmology, University of Cyprus Medical School, Nicosia, Cyprus.
Purpose: To assess the impact of autologous serum (AS) tears at a 50% concentration on the ocular surface of patients with refractory dry eye disease (DED) because of Sjogren syndrome.
Methods: Twenty eyes of ten patients with severe immune-mediated DED were contralaterally randomized to receive either AS tears 50% or artificial tears between June 2021 and May 2023. Changes in tear stability, ocular surface staining, and in the morphology of the corneal sub-basal nerves were evaluated before treatment and at 1, 2, and 3 months after treatment using objective tests for DED and confocal microscopy.
