RESUMO
PURPOSE: This study aimed to evaluate the efficacy of Ahmed glaucoma valve (AGV) implantation with or without anti-VEGF injections in neovascular glaucoma patients. MATERIALS AND METHODS: This single-center retrospective study assessed NVG patients who underwent AGV implantation with or without anti-VEGF injections. Demographic and clinical data, including ocular findings, intraocular pressure (IOP), visual acuity, and glaucoma medication count, were recorded preoperatively and postoperatively at one day, one month, and one year. The study included 35 patients. Group 1 consisted of 23 patients who received anti-VEGF injections before AGV surgery. Group 2, with 12 patients, had no anti-VEGF injections prior to surgery. Successful surgery was defined as IOP values between 6 and 21mmHg. The primary outcome was a 30% or more reduction in IOP. RESULTS: The groups displayed no significant difference in their demographic or clinical profiles (P>0.05). The visual acuity before and one year after surgery did not differ significantly between the groups. However, IOP values significantly decreased by the end of the one-year follow-up for both groups. No significant differences were found between the groups regarding visual acuity, IOP, or the number of medications during the one-year follow-up (P>0.05). Success rates were 95.7% for Group 1 and 91.7% for Group 2. No significant difference in complications between the groups was observed (P>0.05). CONCLUSION: Anti-VEGF injections prior to AGV implantation did not significantly impact visual acuity, IOP values, or medication count during the one-year follow-up.

It has been well established that many types of rapidly dividing normal and diseased cells require an increased amount of folate for DNA replication and repair as well as cellular metabolism. Thus one of folate's cognate receptors, Folate Receptor 1 (FOLR1) is usually up-regulated in rapidly dividing cells, including many types of cancerous tumors. Because zebrafish have become a model organism for understanding conserved vertebrate cellular pathways and human disease, there has been an increased need to identify and elucidate orthologous zebrafish genes that are central to known human maladies. The cells of all early animal embryos go through a phase of rapid division (cleavage) where particular cell cycle checkpoints are skipped until a specification event occurs directing these embryonic stem cells to their fated germ layer cell type. Interestingly, this rapid cell division that ignores cell cycle checkpoints is also observed in many cancers. Developing blastula and tumor cells both require folr1 expression to obtain folate. In this report we have identified the expression pattern of the zebrafish gene zgc:165502, located on chromosome 15. Using computational and comparative methods and molecular biology techniques such as reverse transcription polymerase chain reaction (RT-PCR) and whole mount in situ hybridization (WISH) during embryogenesis, we demonstrate that zgc:165502 is the zebrafish orthologue of the human FOLR1 gene. Understanding when and where FOLR1 orthologues are expressed in different biomedical model organisms such as the zebrafish will help researchers design better experiments to study the endogenous FOLR1 activity.
