A published in 2023 in the journal Journal of Ethnopharmacology found that Traditional Chinese Medicines (TCM) could increase the survival rate of retinal ganglion cells, thereby playing an active role in treating glaucoma. Methodology: The research involved a comprehensive collection and collation of scientific articles from various databases about TCM and its application on glaucoma. The therapeutic effects of TCM, including their specific formulae, crude drugs, and active components, were analyzed based on existing experimental and clinical research. The GSE26299 database was also used for a bioinformatics analysis of glaucoma, employing the GEO database chip. Results: The traditional Chinese medicines exhibited positive effects in treating glaucoma by potentially improving the microcirculation, managing oxidative stress, and regulating the immune system, which in turn increased the survival rate of retinal ganglion cells. Furthermore, the bioinformatics analysis speculated the pathogenesis of glaucoma to be associated with multiple signaling pathways. The study concluded that TCM could alleviate and treat glaucoma through various methods, with the provision that the differentiation syndrome should be the basis for proposing suitable treatment options.

A Network Pharmacology published in 2023 in the journal TMR Pharmacology Research found that Chrysanthemum has several active ingredients that can potentially treat dry eye by inhibiting inflammation-related factors and pathways, thus reducing inflammation of lacrimal gland tissue. The study used network pharmacology methods and various databases to further analyze the mechanism of Chrysanthemum in treating dry eye. First, the TCMSP was used to screen for candidate active ingredient molecules of chrysanthemum showcasing requisite oral bioavailability and drug similarity. The active ingredients of chrysanthemum were then identified, followed by target prediction. Cytoscape was used to construct a compound-target network for chrysanthemum. The Online Mendelian Inheritance in Man and DisGeNET databases were utilized to pinpoint pathogenic genes associated with dry eye, and the STRING database produced an interaction network and bar graph to scrutinize protein interactions. Using Venny, a final drug-active ingredient-key target-disease network was created. The study found that Chrysanthemum has eighty active ingredients corresponding to targets for treating dry eye. These key functional targets primarily regulate gene expression, oxidative stress, immune response, apoptosis, proliferation, regulation of cellular inflammation-related factors, and angiogenesis. The primary pathways associated with these key targets include interleukin signaling, metabolism, cytokine signaling in the immune system, immune system, and signal transduction, thereby improving the condition of dry eye primarily through the inhibition of inflammation-related factors.

A Network Pharmacology published in 2022 in the journal Computational and Mathematical Methods in Medicine found that Compound Chrysanthemum extract may alleviate visual fatigue through its interaction with several components, targets, and pathways. Regarding methodology, this study combined network pharmacology with experimental research to uncover the mechanisms by which Compound Chrysanthemum alleviates asthenopia. Firstly, molecular docking analysis was employed to identify a total of 593 essential genes and 39 chemicals present in the compound. This helped ascertain the affinity between key compounds and receptors, PRKACA, PRKCA, PRKCB. This was followed up with molecular dynamic simulations that further evaluated the stability of these receptors and ligands. Concurrently an in vitro examination of the compound's effect on ciliary muscle was conducted, using MTT assay to study different concentrations of the compound's effect on the proliferation of rCSMCs over 24 and 48 hours. The discussion of the results suggests that the extracts had significant impacts in several areas. Among the notable outcomes of the in vitro experiment was an increase in nitric oxide production and a decrease in Ca in ciliary muscle cells. The compound was also found to have a relaxing effect on the isolated gastric smooth muscle of rats by reducing contractile tension. In an in vivo experiment, rats treated with the compound displayed retracted pupils and increased NO content compared to the model group. A considerable contribution to the understanding of the compound's effect was the acknowledgment of its role in modulating the expression of PKA and PKC in the crucial calcium signaling pathway. The coordinated culmination of these findings indicates the compound's multi-faceted approach to alleviating visual fatigue.

A Experimental Study published in 2022 in the journal BMC Complementary Medicine and Therapies found that Chrysanthemum extract has protective effects on light-damaged retinas, reducing oxidative stress and improving cellular viability. The experiment incorporated both in-vitro and in-vivo tests. In the lab, ARPE-19 cells were divided into four groups (control, light-damaged, low-dose extract, high-dose extract), treated with varying levels of chrysanthemum extract, and then exposed to light. Cellular viability and reactive oxygen species production were then observed. A similar grouping approach was used with C57BL/6J mice, where chrysanthemum extract concentration was administered before light exposure. The retinas were evaluated for function, morphology, and apoptosis post-exposure. Light-damage caused a decrease in cellular viability and an increase in reactive oxygen species production. However, treatment with chrysanthemum extract showed improvement in viability and reduction in reactive oxygen species. In mice, light damage caused dysfunction in the retinas, destruction of morphology and increased apoptosis, particularly in the retinal pigment epithelium and photoreceptor layer. Again, chrysanthemum extract treatment improved retinal function, maintained retinal structures, and reduced apoptosis. The extract achieved this by increasing concentration of anti-oxidative enzymes.

A Review Article published in 2021 in the journal SSRN Electronic Journal found that Phytochemicals in carrots, particularly carotenoids, are effective at reducing eyesight degeneration and treating chronic eye defects due to their antioxidant and anti-inflammatory properties. Throughout the review process, seventy original research and review articles were examined, all published between 2000 and 2020 across four major journal databases: Elsevier, PubMed, ResearchGate and Plos One. The focus of the search was directed by six keywords, centring on both in-vivo and in-vitro study results related to the topic of interest. Among the various findings, it was consistently revealed that carrots contain a multitude of bioactive compounds, notably carotenoids, which have been proven to be effective in halting and treating eye degenerations including Nyctalopia, Myopia, Cataracts, Age-related Macular Diseases and Glaucoma. Carotenoids have been found to work as potent antioxidants and anti-inflammatory agents, defending eyes against vision loss due to oxidative stress. Thus, the increased consumption of carrots can potentially serve as a natural therapeutic approach and enhancer of vision.

A published in 2021 in the journal Tzu Chi Medical Journal found that Traditional Chinese medicine (TCM) can effectively treat dry eye disease (DED), and combining TCM with Western medicine can significantly enhance therapeutic effects and reduce treatment costs. The researchers carried out a comprehensive review of studies conducted from 2001 to 2020, focusing on the use of Traditional Chinese Medicine (TCM) and an integration of Chinese and Western medicine for the treatment of DED. Four categories of Chinese medicines were identified for their application in treating DED: anti-oxidants, anti-inflammatory agents, hormone-like agents, and cell-repairing agents. In addition, they also acknowledged the usage of compound herbs like Chi-Ju-Di-Huang-Wan and Qiming granule for alleviating dry eye symptoms. The researchers arrived at significant findings from their examination of multiple studies. The use of Traditional Chinese Medicine (TCM) has shown effective results in the treatment of Dry Eye Disease (DED). Moreover, the integration of TCM with Western medicine has amplified the therapeutic effects in patients while making the treatment cost-effective. This suggests that not only can TCM be a promising approach for treating DED, but a combined treatment strategy with Western medicine can also lead to substantial improvements in curing the condition.

A Randomised Controlled Trial published in 2020 in the journal The American Journal of Clinical Nutrition found that A botanical formula of lutein ester, zeaxanthin, and extracts from blackcurrant, chrysanthemum, and goji berry can effectively lessen eye fatigue and improve macular function. Research methodology involved the distribution of 360 randomly selected participants into four groups where they received placebos and three varied doses of a botanical formula. This formula, given in chewable tablets comprised of 6 mg, 10 mg, or 14 mg of lutein. Each participant was administered these once daily over a period of 90 days, and had three check-ins at the beginning, at day 45, and finally on day 90 of the study. The results of the study indicated that the botanical formula effectively improved the individual scores of participants on eye fatigue symptoms like eye soreness, blurred vision, dry eyes, foreign body sensation, and tearing. Using the formula resulted in a notable decrease in the total score of eye fatigue symptoms at both the 45-day and 90-day intervals as compared to the placebo while also significantly improving visuognosis persistence time. Tear secretion improvement was observed in the groups having 10mg and 14mg lutein formula, supported by the Schirmer test. Furthermore, the results showed an increase in macular pigment optical density with all three doses of the formula, but no significant alterations were observed in the retinal thickness and retinal volume among all the groups at both check-ins.

A Clinical Study published in 2019 in the journal Molecules found that Anthocyanin supplements improve vision health by relaxing ciliary muscles, regenerating rhodopsin, and enhancing retinal blood circulation. The methodology of this review involved studying the effects of Anthocyanin, a supplement popular for eye health. Despite the low bioavailability of Anthocyanin, the supplement is reported to appear in intact form and in various metabolites. The review observes how Anthocyanin crosses barriers within the blood to reach the ocular area. The study also performed an in vitro analysis to comprehend how Anthocyanin impacts the ciliary muscles of the eye, crucial in treating vision conditions like myopia and glaucoma. Findings of the review reveal that Anthocyanin also stimulates the reformation of rhodopsin in the rod outer segment of frogs. The compound further demonstrated how to control eye elongation in a model of chick myopia induced by a negative lens. Ultimately, the review consolidated multiple clinical studies that provide evidence for the improvement of dark adaptation and transient myopic shift following intake of Anthocyanin. The supplement notably improves retinal blood circulation among patients with normal tension glaucoma.

A Review Article published in 2019 in the journal Applied Ecology and Environmental Research found that Chrysanthemum, rich in unique chemical compounds, offers significant health benefits such as stress relief, cardio protection, immunity boost, improved eye health, and osteoporosis risk reduction. The study primarily focuses on evaluating the most important chemical extracts of chrysanthemum. These include flavonoids, betaine, choline, and vitamin B1. Further, the researchers identified thirteen compounds unique to chrysanthemum flowers. These were extracted and analyzed to unveil their potential health benefits. In the discussion of results, the authors highlight chrysanthemum's impressive range of health benefits stemming from its chemical composition. It is revealed that chrysanthemum can potentially alleviate stress and anxiety while improving cardiovascular health. It also has properties to guard against oxidative damage and inflammation, support a healthy immune function, enhance eye health, and lessen the risk of osteoporosis. Interestingly, the herb's beneficial traits align with its traditional use in Chinese medicine, underscoring chrysanthemum's potential in promoting holistic, organic health.

A Theoretical Article published in 2019 in the journal Applied Ecology and Environmental Research found that Chrysanthemum, a plant primarily grown in China and Japan, offers significant health benefits including stress reduction, cardiovascular improvement, and lowering osteoporosis risk. The study focused on Chrysanthemum, a notable plant in the ornamental industry and traditional Chinese medicine, mainly grown in China and Japan. The researchers identified its crucial chemical extracts such as flavonoids, betaine, choline, and vitamin B1. They additionally pinpointed thirteen significant compounds of chrysanthemum flowers, including acacetin-7-0-beta- D-glucopyranoside, luteolin, acaciin, and boscialin, among others. The findings revealed that chrysanthemum tea exhibits considerable health advantages. It eases stress and anxiety, enhances cardiovascular health, protects against oxidative damage, inhibits inflammation, supports healthy immune function, ameliorates eye health, and decreases the risk for osteoporosis. In traditional Chinese medicine, chrysanthemum is considered a cold herb that dispels pathogenic heat, aids the liver, improves eyesight, and promotes detoxification. The study, therefore, endorsed the treatment with natural Chinese herbal medicine, especially chrysanthemum, over synthetic drugs for a more organic life.

A Randomised Controlled Trial published in 2018 in the journal International Journal of Ophthalmology found that Goji berry supplementation can improve macular pigment and visual acuity in patients with early age-related macular degeneration by increasing serum zeaxanthin levels. In this prospective, randomized controlled study, 114 patients, aged 51 to 92 and with early age-related macular degeneration, were divided into two groups. One group was given a daily supplementation of 25 grams of Goji berries for 90 days while the control group continued with their normal diet. The study used Heterochromatic Flicker Photometry to measure the Macular Pigment Optical Density (MPOD) and High-Performance Liquid Chromatography to analyze the levels of serum lutein and zeaxanthin. These were recorded at the beginning and at the end of the study. In the Goji berry group, by the end of the study, there was no significant change in serum lutein levels. However, there was an increase in serum zeaxanthin levels which coincided with the group's improvement in MPOD. In comparison to the control group, the Goji group had higher zeaxanthin levels and MPOD. The visual acuity of the Goji berry group also showed a relative decrease compared to the baseline. These results suggest Goji berry supplementation can beneficially impact early age-related macular degeneration patients by boosting serum zeaxanthin levels, thus raising MPOD and improving visual acuity.

A Randomised Controlled Trial published in 2011 in the journal Optometry and Vision Science found that Daily goji berry supplementation increases antioxidant levels and protects visual health in the elderly, though the exact mechanism remains unclear. In a double-masked, randomized, placebo-controlled study, elderly participants were given either a milk-based goji berry supplement (13.7 g/d) or a placebo for a 90-day period. Eye health was assessed via direct examination to measure pigmentation and soft drusen count in the macula, and blood tests were done to determine plasma zeaxanthin level and total antioxidant capacity. In the discussion of results, the placebo group showed signs of hypopigmentation and soft drusen accumulation in the macula, which did not occur in the group that received the goji berry supplement. The group supplementing with goji berries also showed a significant increase in plasma zeaxanthin levels and total antioxidant capacity, while no change was seen in the placebo group. There were no adverse effects of the supplement reported in either group.
