Although choroidal neuropathy has been observed in rodent models of pachychoroid, its presence in human chronic CSCR remains unclear and difficult to examine. Because the long ciliary nerves send fibers to both the cornea and the choroid, this study used in vivo confocal microscopy to examine corneal nerve fiber (CNF) morphology in chronic CSCR patients compared with age-matched controls.</div></div><div><h3>Design</h3><div>The case-control study included chronic CSCR and control participants without signs or symptoms of corneal disease to detect the presence of nerve abnormalities.</div></div><div><h3>Subjects</h3><div>The study analyzed corneal nerves in 15 chronic CSCR patients and 11 control subjects with subfoveal thickness ≤360 μm.</div></div><div><h3>Methods/Testing</h3><div>In vivo confocal microscopy was used to image and systematically analyze the subepithelial area, Bowman layer (BL), anterior stroma, intermediate stroma, and deep stroma. Corneal nerve fiber abnormalities were scored according to their types, location, and number in the different layers by 2 graders in a blind manner. Corneal nerve fibers were quantified in the sub-basal nerve plexi in both groups (chronic CSCR and controls), and subfoveal choroidal thickness was measured using OCT enhanced depth imaging mode.</div></div><div><h3>Main Outcome Measures</h3><div>Scores of CNF abnormalities in all layers and quantification of CNF in the sub-basal plexi.

In contrast, nearly all CSCR patients exhibited significant CNF abnormalities, including hypertrophic subepithelial nerve plexi, loops, neuromas, cell clusters, dendritic cells activation, and nerve rarefaction. In addition, quantification of BL innervation shows a significant reduction in CSCR patients, indicating corneal nerve abnormalities.</div></div><div><h3>Conclusions</h3><div>In vivo confocal microscopy reveals morphological nerve abnormalities in chronic CSCR patients, potentially reflecting underlying choroidal neuropathy and subsequent blood flow dysregulation. These findings suggest corneal nerve changes may serve as a noninvasive marker warranting investigation into shared neuropathic mechanisms.

Multivariable adjustment included birth weight (BW), gestational age (GA), bronchopulmonary dysplasia (BPD), intraventricular hemorrhage, necrotizing enterocolitis (NEC), and neonatal sepsis.

The rate of systemic antibiotic use was 97.3% in the control group and 100.0% in infants with type 1 ROP. Infants with type 1 ROP showed higher rates of BPD (<em>P</em> < 0.001) and bacterial infection (<em>P</em> = 0.007). No association was noted with NEC. In multivariable regression, the odds of treatment were significantly greater for infants receiving cephalosporins, carbapenems, and monobactams (odds ratio [OR], 4.25; 95% confidence interval [CI], 1.74–10.4; <em>P</em> = 0.002), and an exploratory analysis suggested a dose-response per day prescribed (OR, 1.07; 95% CI, 1.03–1.11; <em>P</em> = 0.001). When restricted to BW <750 g or GA <27 weeks (N = 259, with 49 treated for ROP), these associations remained significant (OR, 3.87; 95% CI, 1.57–9.51; <em>P</em> = 0.003; per day prescribed: OR, 1.07; 95% CI, 1.03–1.11; <em>P</em> = 0.001). After propensity score matching for BW, GA, BPD, sepsis, and any bacterial infection, the average percent of infants who required treatment was 9.9 percentage points higher among those who received cephalosporins, carbapenems, and monobactams compared to those same infants if they had not received them (95% CI, 2.0–17.8 percentage points; <em>P</em> = 0.014).</div></div><div><h3>Conclusions</h3><div>Early exposure to broad-spectrum antibiotic classes, particularly cephalosporins, carbapenems, and monobactams, may be associated with type 1 ROP.</div></div><div><h3>Financial Disclosure(s)</h3><div>The authors has no/the authors have no proprietary or commercial interest in any materials discussed in this article.</div></div>","PeriodicalId":74363,"journal":{"name":"Ophthalmology science","volume":"6 1","pages":"Article 100919"},"PeriodicalIF":4.6,"publicationDate":"2025-08-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145268155","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The mean age was 60.6 ± 10.6 years, with 30 (58.8%) female patients. Prior surgeries included peripheral iridectomy (23 eyes), trabeculectomy (39 eyes), XEN Gel implant (1 eye), Ahmed valve implant (1 eye), and phacoemulsification and intraocular lens implantation (17 eyes). Among these, complete success was achieved in 26 eyes (42.6%) and qualified success in 52 eyes (85.2%).

Complications included hyphema (n = 7), IOP spikes (n = 6), mild corneal edema (n = 3), and shallow anterior chamber (n = 2), all within the first postoperative month.
