Summary: This study investigated the effects of two extracts from Acer palmatum leaves on dry eye. The results showed that the extracts increased tear production, reduced inflammation and cell death, and alleviated dry eye symptoms. Topical administration of KIOM-2015EE demonstrated better therapeutic effects compared to oral administration.

Summary: This study evaluated the noninferiority of a small-volume eye drop adapter, the Nanodropper, compared to the standard of care in terms of pupillary dilation and cycloplegia in children. The results showed that the efficacy of the small-volume eye drops was comparable to the standard treatment, indicating the potential to reduce medical waste and medication toxicity.

Summary: This study used a mouse model of dry eye disease induced by BAK to examine its stability and the presence of neurosensory abnormalities. The results showed that BAK treatment significantly increased corneal fluorescein staining, ocular pain, leukocyte infiltration, and reduced corneal sensitivity and tear secretion. Moreover, discontinuation of BAK treatment improved corneal epithelial damage. Therefore, BAK is an important factor contributing to DED.

Summary: Dry eye disease (DED) is a complex ocular surface inflammatory disease that varies widely in its occurrence worldwide. The use of benzalkonium chloride in ocular drops worsens DED conditions, and the Covid-19 pandemic has resulted in an increase in DED cases. The study found that capsanthin from Capsicum annum can effectively manage DED by reducing intraocular pressure and inflammation.

Summary: Dry eye disease is a common ocular condition that greatly impacts life quality and presents challenges in ophthalmology. Animal models were used to compare and standardize two rodent models of dry eye disease, and explore their recovery aspects. The study found chronic inflammation in the cornea and lacrimal gland in benzalkonium-treated group, while the scopolamine-treated group showed chronic inflammation in the lacrimal gland initially and later in the cornea. The recovery study suggested the usefulness of the models in evaluating dry eye treatments.

Summary: In this study, TAT-MT liposomes were developed to inhibit BAC-induced dry eye disease (DED). It was found that TAT-MT liposomes significantly alleviated DED symptoms by suppressing tissue inflammation and preventing the loss of corneal epithelium and conjunctival goblet cells. The study also revealed a new mechanism of BAC-induced corneal epithelial pyroptosis mediated by NLRP3/Caspase-1/GSDMD, and suggested the potential of TAT-MT liposomes as a new treatment for DED.

Summary: Dry eye disease (DED) is a global health issue and novel therapies have been developed for its treatment. Reliable animal models of DED are necessary for testing these therapies, and benzalkonium chloride (BAC) induced DED models have been described in literature. BAC induces inflammation and instability of tear film, simulating human DED. The stability of these models determines the timing of treatment. These models show promise and continue to be used in studies on therapeutic drugs for DED treatment.

Summary: In recent years, personal care products (PCPs) have been identified as a new class of pollutants that pose potential risks to non-target organisms when released into wastewater treatment plants and receiving environments. This paper reviews the occurrence, toxicological effects, and microbial degradation mechanisms of four selected preservatives commonly found in PCPs. The presence of these preservatives has been widely detected in aquatic environments and sewage sludge due to insufficient removal from WWTPs. They have been found to be toxic to aquatic and terrestrial organisms, but formed metabolites are generally less toxic than the parent compounds. Further research is needed to assess the environmental concentrations and toxicity of preservatives in diverse matrices and to understand the microbial degradation mechanisms. Focus should be given to the least understood preservatives, chloroxylenol and methylisothiazolinone.

Summary: This study found that the bacterial communities on the ocular surface changed significantly after the use of sodium hyaluronate eye drops. Regardless of the presence of preservatives, eye drops have an impact on the bacterial communities on the ocular surface.

Summary: The results of the study demonstrate that 0.05%-0.1% rhTβ4 eye drops can significantly improve clinical parameters in DED patients, increase conjunctival goblet cells, and reduce apoptotic cells in the conjunctiva. Additionally, by inhibiting NF-KB activation, rhTβ4 can significantly reduce inflammatory cytokine levels and CD4(+) T cells in the conjunctiva, suggesting that 0.05-0.1% rhTβ4 eye drops may be a potential therapeutic treatment for DED.

Summary: Glaucoma is a major cause of irreversible blindness, and reducing intraocular pressure (IOP) with eye drops is the most common treatment approach. However, the many side effects of eye drops often lead to reduced patient adherence. This review discusses the various molecular components of IOP-lowering eye drops and highlights important considerations when prescribing topical glaucoma treatment.

Summary: This study evaluated the noninferiority of latanoprost without benzalkonium chloride (BAK) compared to latanoprost with BAK in lowering intraocular pressure (IOP). The results showed that latanoprost without BAK did not meet two out of three criteria for noninferiority, but had a similar safety profile to latanoprost with BAK.

Summary: This study investigates the protective effects of allyl isothiocyanate (AITC) on the ocular surface in a benzalkonium chloride (BAC)-induced dry eye rat model. AITC supplementation significantly improved various histopathologic and ophthalmologic findings, balanced the inflammatory status and oxidative stress, and recovered levels of protective tear proteins. The antioxidative and anti-inflammatory properties of AITC play a significant role in its mechanism of action.

Summary: We report a case of a large and hypervascular orbital solitary fibrous tumor (SFT) that was successfully embolized with 500-700 μm tris-acryl gelatin microspheres (TAGM) before surgery. No complications, tumor recurrence, or metastasis were observed during the 42-month postoperative follow-up.

Summary: This study demonstrated that patients with internal carotid artery stenosis have lower macular thickness and measurements in the outer macular quadrants compared to healthy individuals, suggesting that macular changes may occur before symptomatic ocular ischemic syndrome. The findings also indicate that SD-OCT macular measurements could be helpful in the early detection of OIS related to internal carotid artery stenosis.
