Comparative Efficacy of Anti-vascular Endothelial Growth Factor (Anti-VEGF) Agents and Corticosteroids in Managing Diabetic Retinopathy-Associated Diabetic Macular Edema: A Meta-Analysis and Comprehensive Systematic Review. Cureus 2024; 16:e51910. [PMID: 38333510 PMCID: PMC10850611 DOI: 10.7759/cureus.51910] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/02/2024] [Accepted: 01/08/2024] [Indexed: 02/10/2024] Open
Abstract
Diabetic macular edema (DME) is a significant condition linked to diabetes that can result in visual loss. In recent times, there has been a notable change in the desire for treatment, with a shift toward anti-vascular endothelial growth factor (anti-VEGF) therapy and intravitreal steroids while moving away from conventional laser therapies. This comprehensive meta-analysis explicitly compares the efficacy of two therapies for DME: anti-VEGF therapy and corticosteroid. We conducted a thorough search using PubMed and Google Scholar to identify publications that compare the effects of anti-VEGF therapy and corticosteroid implants on DME. Using Review Manager 5.0 (RevMan), we incorporated data from nine research studies, which involved a total of 877 people. The group was split into two factions: 453 patients were administered corticosteroids, while 466 patients underwent treatment with anti-VEGF therapy. Our investigation demonstrated that both corticosteroid and anti-VEGF therapy positively improved the best-corrected visual acuity (BCVA) and reduced the central macular thickness (CMT). Nevertheless, comparing the mean BCVA on the logarithm of the minimum angle of resolution (logMAR) scale revealed no statistically significant changes between the two treatments. This indicates considerable inconsistency, as evidenced by the weighted mean difference (WMD) of -0.13 (-0.41, 0.16) with a P-value of 0.39 and an I2 value of 99%. In addition, both treatments improved BCVA compared to the initial measurement. However, there was no statistically significant benefit for corticosteroid over anti-VEGF therapy, as indicated by the WMD of 0.03 (-0.07, 0.13) with a P-value of 0.55 and an I2 value of 80%. The examination of the average CMT also yielded findings that lacked statistical significance, displaying a significant amount of variation (WMD -36.37, 95% confidence interval [-127.52, 54.78], P = 0.43, I2 = 98%). Remarkably, there were no significant alterations among the anti-VEGF therapy group despite a rise in CMT from the initial measurement. The main conclusion drawn from our research is that corticosteroid demonstrates encouraging immediate enhancements in BCVA and CMT. However, anti-VEGF therapy seems to provide more significant long-term advantages. Nevertheless, it is crucial to acknowledge that the corticosteroid group had a greater susceptibility to acquiring elevated intraocular pressure (IOP) and the possibility of glaucoma.

Abstract
This case report depicts how a case of the subretinal neovascular membrane was managed with intravitreal ranibizumab injections. A 59-year-old female patient presented with complaints of diminution of vision in her right eye for one month. Various necessary examinations were carried out and the patient was diagnosed with both forms of age-related macular degeneration (ARMD) disorder - wet ARMD in the right eye and dry ARMD in the left eye. Pseudophakia was also seen in both eyes. Drusen deposits, characteristic of the disorder, were seen in the macular area of the oculus sinister (OS). The patient was treated for the wet ARMD with intravitreal injections of 0.5 mg ranibizumab administered one month apart in the right eye. The patient showed improvements in her visual acuity and a complete resolution of the subretinal fluid.

Abstract
BACKGROUND Glaucoma, a characteristic type of optic nerve degeneration in the posterior pole of the eye, is a common cause of irreversible vision loss and the second leading cause of blindness worldwide. As an optic neuropathy, glaucoma is identified by increasing degeneration of retinal ganglion cells (RGCs), with consequential vision loss. Current treatments only postpone the development of retinal degeneration, and there are as yet no treatments available for this disability. Recent studies have shown that replacing lost or damaged RGCs with healthy RGCs or RGC precursors, supported by appropriately designed bio-material scaffolds, could facilitate the development and enhancement of connections to ganglion cells and optic nerve axons. The consequence may be an improved retinal regeneration. This technique could also offer the possibility for retinal regeneration in treating other forms of optic nerve ailments through RGC replacement. METHODS In this brief review, we describe the innovations and recent developments in retinal regenerative medicine such as retinal organoids and gene therapy which are specific to glaucoma treatment and focus on the selection of appropriate bio-engineering principles, biomaterials and cell therapies that are presently employed in this growing research area. RESULTS Identification of optimal sources of cells, improving cell survival, functional integration upon transplantation, and developing techniques to deliver cells into the retinal space without provoking immune responses are the main challenges in retinal cell replacement therapies. CONCLUSION The restoration of visual function in glaucoma patients by the RGC replacement therapies requires appropriate protocols and biotechnology methods. Tissue-engineered scaffolds, the generation of retinal organoids, and gene therapy may help to overcome some of the challenges in the generation of clinically safe RGCs.

Abstract
This study aimed to investigate the effect of hematoporphyrin dimethylether (HDME)-mediated photodynamic therapy for laser-induced choroidal neovascularization (CNV) in adult Brown Norway rats. HDME was administered via tail vein at 14 d after the laser photocoagulation, and the rats received irradiance with a laser light at 570 nm at 15 min after injection. CNV was evaluated by fundus photography, fundus fluorescein angiography, optical coherence tomography, and hematoxylin and eosin staining. We found that CNV was occurred at 7 d after photocoagulation and reaching peak activity at 14 d after photocoagulation. There is a significant reduction in the total area of the fluorescein leakage and the number of strong fluorescein leakage spots on 7 d after HDME-mediated photodynamic therapy (PDT). The results suggest that HDME-mediated PDT inhibits laser-induced CNV in rats, representing a promising therapy for wet age-related macular degeneration.

Abstract
As clinical nanomedicine has emerged over the past two decades, phototherapeutic advancements using nanotechnology have also evolved and impacted disease management. Because of unique features attributable to the light activation process of molecules, photonanomedicine (PNM) holds significant promise as a personalized, image-guided therapeutic approach for cancer and non-cancer pathologies. The convergence of advanced photochemical therapies such as photodynamic therapy (PDT) and imaging modalities with sophisticated nanotechnologies is enabling the ongoing evolution of fundamental PNM formulations, such as Visudyne®, into progressive forward-looking platforms that integrate theranostics (therapeutics and diagnostics), molecular selectivity, the spatiotemporally controlled release of synergistic therapeutics, along with regulated, sustained drug dosing. Considering that the envisioned goal of these integrated platforms is proving to be realistic, this review will discuss how PNM has evolved over the years as a preclinical and clinical amalgamation of nanotechnology with PDT. The encouraging investigations that emphasize the potent synergy between photochemistry and nanotherapeutics, in addition to the growing realization of the value of these multi-faceted theranostic nanoplatforms, will assist in driving PNM formulations into mainstream oncological clinical practice as a necessary tool in the medical armamentarium.

Abstract
Age-related macular degeneration (AMD) is the leading cause of blindness in the elderly. Choroidal neovascularization (CNV) is the abnormal angiogenesis that causes severe visual loss in AMD. Fibulin-5 (Fbln5), which functions as an angiogenesis inhibitor, plays an important role in the pathogenesis of AMD. Here, we investigated whether subretinal transplantation of Fbln5-overexpressing retinal pigment epithelial (RPE) cells can inhibit CNV in vivo. Adult Long-Evans rats were used in this study. CNV was induced by laser photocoagulation. One week after laser-induced CNV, RPE cells expressing pZlen-Fbln5-IRES-GFP or the control pZlen-IRES-GFP vectors were transplanted into the subretinal space of the right and left eyes, respectively. CNV was evaluated using fundus photography, fundus fluorescein angiography (FFA), and hematoxylin and eosin staining. We found that CNV occurred at 1 week after photocoagulation, reaching peak activity at 3 weeks and remaining at a high level at 4-5 weeks after photocoagulation. Transplanted RPE cells survived for at least 4 weeks and migrated toward the retina. Subretinal transplantation of Fbln5-overexpressing RPE cells resulted in a significant reduction in the total area of leakage and the number of leakage spots compared with transplantation of RPE cells expressing only green fluorescent protein. Our findings suggest that subretinal transplantation of Fbln5-overexpressing RPE cells inhibits laser-induced CNV in rats and thus represents a promising therapy for the treatment of AMD.

Abstract
CONTEXT Graves' orbitopathy (GO) is caused by expansion of the orbital contents by excess adipogenesis and overproduction of hyaluronan (HA). Immunosuppressive and antiinflammatory treatments of GO are not always effective and can have side effects, whereas targeting GO-associated tissue remodeling might be a more logical therapeutic strategy. Previously we reported that signaling cascades through IGF1 receptor and thyrotropin receptor within orbital preadipocytes/fibroblasts drove adipogenesis and HA production. Our current study combined the stimulation of IGF1 receptor and thyrotropin receptor increase of HA accumulation, which we hypothesize is by activation of phosphatidylinositol 3-kinase (PI3K)-1A/PI3K1B, respectively. The central aim of this study was to investigate whether PI3K/mammalian target of rapamycin complex 1 (mTORC1) inhibitors affected adipogenesis and/or HA production within orbital preadipocyte/fibroblasts. METHODS Human orbital preadipocytes were treated with/without inhibitors, LY294002 (PI3K1A/mTORC1), AS-605240 (PI3K1B), or PI103 (PI3K1A/mTORC1) in serum-free medium for 24 hours or cultured in adipogenic medium for 15 days. Quantitative PCR was used to measure hyaluronan synthases (HAS2) transcripts and the terminal adipogenesis differentiation marker lipoprotein lipase. HA accumulation in the medium was measured by an ELISA. RESULTS Unlike AS-605240, both LY294002 (10 μM) and PI-103 (5 μM) significantly decreased HAS2 transcripts/HA accumulation and adipogenesis. Because PI-103 and LY294002 are dual PI3K/mTOR inhibitors, we investigated the inhibition of mTORC1 (rapamycin 100 nM), which significantly decreased adipogenesis but had no effect on HAS2 transcripts/HA, implicating PI3K-1A in the latter. CONCLUSIONS The combined inhibition of PI3K1A and mTORC1 signaling in vitro decreased both HA accumulation and adipogenesis. Because PI3K and mTOR inhibitors are clinically used to treat other conditions, they have the potential to be repositioned to be used as an alternative nonimmunosuppressive therapy of GO.

Abstract
Age-related macular degeneration (AMD) is the most common cause of blindness in the elderly population worldwide and is defined as a chronic, progressive disorder characterized by changes occurring within the macula reflective of the ageing process. At present, the prevalence of AMD is currently rising and is estimated to increase by a third by 2020. Although our understanding of the several components underpinning the pathogenesis of this condition has increased significantly, the treatment options for this condition remain substantially limited. In this review, we outline the existing arsenal of therapies available for AMD and discuss the additional role of further novel therapies currently under investigation for this debilitating disease.

Abstract
The challenge in the treatment of chronic retinal diseases is to deliver effective therapy to the target tissues in the back of the eye while limiting drug exposure in nontarget tissues. Intravitreal placement provides the most targeted drug delivery, but repeated penetration of the globe to deliver intravitreal therapy can pose safety risks. A more effective strategy for the treatment of chronic retinal diseases would be to combine intravitreal placement with sustained drug delivery. The dexamethasone intravitreal (DEX) implant is a biodegradable sustained-release intravitreal drug delivery system that is approved for the treatment of macular edema following branch or central retinal vein occlusion and for noninfectious uveitis affecting the posterior segment of the eye. A single DEX implant has been shown to provide clinical benefits for up to 6 months in eyes with retinal vein occlusion or intermediate or posterior uveitis.

Abstract
Rapid progress in genomics and nanotechnology continue to advance our approach to patient care, from diagnosis and prognosis, to targeting and personalization of therapeutics. However, the clinical application of molecular diagnostics in ophthalmology has been limited even though there have been demonstrations of disease risk and pharmacogenetic associations. There is a high clinical need for therapeutic personalization and dosage optimization in ophthalmology and may be the focus of individualized medicine in this specialty. In several retinal conditions, such as age-related macular degeneration, diabetic macular edema, retinal vein occlusion and pre-threshold retinopathy of prematurity, anti-vascular endothelial growth factor therapeutics have resulted in enhanced outcomes. In glaucoma, recent advances in cytoskeletal agents and prostaglandin molecules that affect outflow and remodel the trabecular meshwork have demonstrated improved intraocular pressure control. Application of recent developments in nanoemulsion and polymeric micelle for targeted delivery and drug release are models of dosage optimization, increasing efficacy and improving outcomes in these major eye diseases.
