Methods We conducted a prospective, non-randomised clinical trial that enrolled 63 AACE patients with a disease course of 6 months to 2 years and deviation angles of 15 to 60 prism diopters. The patients were assigned to BTXA (n=31) and aMRc group (n=32). We compared and analysed the deviation angles, fusion amplitudes (FA) of convergence and divergence, stereopsis, and scores of QOL and diplopia between the two groups before treatment and at 2, 4, 6 and 12 months post-treatment. Results Both groups exhibited significant improvements in motor and sensory outcomes. The aMRc group showed more stable and satisfactory deviation than the BTXA group at 6 and 12 months post-treatment, with a significant increase in divergent FA. The aMRc group achieved a higher success rate (93.75%) than the BTXA group (64.52%) 1 year post-treatment. QOL improved significantly in both groups after treatment, except for reading function in the BTXA group. Compared with the BTXA group, the aMRc group showed greater improvements in self-perception, general function, and diplopia scores (p<0.05). Survival analysis revealed a significant difference between the two groups (p=0.0046). Treatment method and convergent FA at near before treatment were identified as recurrence predictors (p=0.023 and 0.025). Conclusions Augmented MRc treatment was superior to BTXA injection in AACE patients with courses >6 months during 1-year observation, particularly in maintaining alignment, eliminating diplopia and improving divergent FA and QOL.

Progression was defined as either structural or functional deterioration. Cox proportional hazard modelling was employed to identify factors for progression. Kaplan-Meier survival analysis was used to compare cumulative progression probability in PPG patients with or without optic disc haemorrhage (DH).RESULTSAmong the PPG subjects included, 44 eyes (35.5%) converted to POAG, with a mean deviation change of -0.39±0.64 dB/year over a mean follow-up of 12.2±4.2 years. The mean time to conversion was 5.3±2.2 years. Within the conversion group, 30 eyes (68.2%) exhibited functional progression, 23 eyes (52.3%) showed structural progression and nine eyes (20.5%) demonstrated both. Factors significantly associated with glaucoma progression were migraine/headache (HR=2.19, p=0.012), reduction of intraocular pressure (IOP; HR=0.75, p=0.009), and disc haemorrhage (DH; HR=3.78, p<0.001). Notably, patients with DH exhibited higher cumulative probability of progression compared with those without DH (p=0.017).CONCLUSIONSThis study of PPG with more than 10 years of follow-up demonstrates a substantial proportion (35.5%) converting to POAG, highlighting the need for long-term monitoring in these patients. PPG with insufficient IOP reduction and DH was associated with significantly higher cumulative probability of progression, emphasising its prognostic significance in PPG patients.","PeriodicalId":9313,"journal":{"name":"British Journal of Ophthalmology","volume":"42 1","pages":""},"PeriodicalIF":4.1,"publicationDate":"2025-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145153361","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Demographic, clinical and multimodal imaging data were collected and compared. Univariable and multivariable regression analyses were performed to assess risk factors.RESULTSAmong 69 eyes, 16 were classified as RCH-MS, 33 as RCH-ME and 20 as RCH-MT. Compared with RCH-MS, RCH-ME and RCH-MT exhibited significantly worse visual acuity. Multivariable analysis revealed that RCH-MT was associated with greater tumour-to-foveola distance (OR 1.347, 95% CI 1.024 to 1.771) and higher prevalence of fibrovascular proliferation overlying the RCH (OR 14.371, 95% CI 1.622 to 127.301).

Methods The medical charts of patients from nine vitreoretinal services across the UK who, between 2009 and 2023, underwent PPV for different indications and subsequently developed sFTMH were retrospectively reviewed. Primary outcomes were clinical features, macular hole closure rate and change in best corrected visual acuity (BCVA). Patients with idiopathic FTMH (iFTMH) who underwent surgical repair in the same period acted as control data for optical coherence tomography (OCT) characteristics. Results Out of 16 939 PPV undertaken during the study period, 60 eyes of 60 patients (52% females, mean age 61.9 years) developed sFTMH, leading to an incidence of 0.4%. Median follow-up was 24.7 months. The median time from primary PPV to sFTMH diagnosis was 3 (range 0.4–81.4) months. OCT features of sFTMH were compared with 108 cases of iFTMH.

Patients were categorised into mild, moderate or advanced glaucoma groups based on the International Classification of Diseases 10th criteria. ONH parameters were measured, including disc area, tilt angle, β-zone and γ-zone parapapillary atrophy (PPA) areas and lamina cribrosa (LC) metrics. These parameters were compared across severity groups using analysis of variance. Pearson’s correlation and linear regression analyses were conducted, adjusting for axial length (AXL).
