Introduction: Postoperative strabismus inflammation can lead to fibrotic tissue formation. Dexamethasone, while generally effective as an anti-inflammatory post-surgery medication, can increase IOP and blood sugar levels. Research on asiatic acid suggests its potential as an anti-inflammatory and anti-fibrotic agent. Methods: Superior rectus recession was conducted on 20 rabbits, which were divided into five groups based on the subconjunctival injection substance: aquadest, dexamethasone, asiatic acid at a concentration of 0.4 mg/0.5 mL, 0.8 mg/0.5 mL, and 1.6 mg/0.5 mL. After three days, exenteration was performed, and an immunohistochemical examination was performed to assess interleukin-4 expression. Hematoxylin and eosin staining was performed to assess eosinophile cell count. SPSS 26.0 facilitated the data analysis using the Kruskal-Wallis and Wilcoxon Mann-Whitney tests. P\<0.05 was considered significant statistically. Results: This study showed that interleukin-4 expression in the asiatic acid 0.4 mg/0.5 mL group was significantly decreased compared to the aquadest group (P = 0.029) and dexamethasone group (P = 0.029). Higher-dose groups did not exhibit a significant decrease. Dexamethasone also did not exhibit a significant decrease compare to aquadest. There was no significant reduction of eosinophile cell count among all groups. Conclusions: This study highlighted the potential of asiatic acid, particularly at the concentration of 0.4 mg/0.5 mL, in reducing the inflammatory response, specifically interleukin-4 expression, after strabismus surgery in New Zealand rabbits.

Introduction: Chemical trauma to the eye is a serious condition in the field of ophthalmology and a leading factor contributing to global blindness. Cicatrizing conjunctivitis (CC) is a term used to describe conditions marked by inflammation and the formation of scars on the conjunctiva. CC can have various causes, with one of them being chemical injury to the eye. The development of CC involves the participation of several cytokines and cells, such as α-SMA, Type 1 collagen, and Myofibroblasts. Myofibroblasts have the ability to contract through the utilization of diverse cytoskeletal proteins, which are commonly present in smooth muscle cells, including α-SMA. Actin filaments contribute to mechanically supporting cells, defining cell morphology, and facilitating cell mobility. Actin, in conjunction with myosin, participates in the muscle contraction process within muscle cells. Subsequently, type 1 collagen contributes to the healing of conjunctival wounds by providing a tensile force that aids in the closure of such wounds. As a significant constituent of the extracellular matrix, type 1 collagen plays a crucial role in maintaining the integrity of tissues.

Purpose: This study aims to investigate the effects of topical Medroxyprogesterone acetate (MPA) and Doxycycline in inhibiting the expression of MMP-3 and TIMP-1 in ocular alkali burn models in animals. Methods: A total of 18 New Zealand Rabbits were divided into 3 groups based on their post-alkali-burn treatment: PBS (G1/ control group), topical Doxycycline 1mg/ml (G2), and topical MPA 1\% (G3). Alkali burn models were made by exposing 1N NaOH solution to the central cornea for 30 seconds. MMP-3 and TIMP-1 expression were evaluated using immunohistochemistry after 14 days of treatment. Results: Statistically significant differences in the mean MMP-3 expression were found between the three groups (p=0.010). There was a significant difference in MMP-3 expression between the control group with MPA (p=0.017) and Doxycycline (p=0.028) but was not found between the MPA and Doxycycline groups (p=1,000). The mean differences in TIMP-1 expression between the three treatment groups were statistically significant (p=0.005), with a significant difference between the control group with Doxycycline (p=0.022) and MPA (p=0.007). There was no significant difference in TIMP-1 expression between the Doxycycline and MPA groups (P=1,000). Conclusion: This study indicated that topical administration of Doxycycline or MPA in ocular alkali burn reduces the expression of MMP-3 and TIMP-1.

Background: Glaucoma is an optic neuropathy caused by the apoptosis of retinal ganglion cells and results in progressive retinal ganglion cell injury. A decrease in intraocular pressure (IOP) is a modifiable risk factor for slowing the progression of the disease, and can be accomplished through medication, laser therapy, or surgery. Even though the intraocular pressure has decreased and attained normal levels, the injury to the retinal ganglion cells continues in some cases. It is believed that neuroprotective administration has a positive effect on preventing the loss of retinal ganglion cells. Methods: Bax and Caspase-3 expression were measured involving 20 eyeballs of Rattus Norvegicus by immunohistochemistry examination. I-R injury was developed by increasing intraocular pressure (IOP) through the intracameral balanced salt solution (BSS) injection, then lowered after 60 minutes. Samples were divided into 4 groups: control, no further injection group, phosphate-buffered saline (PBS)-injected group and resveratrol-injected group. Each group was enucleated at days 7, 0, 7, and 7, respectively. Data with a non-normal distribution were examined using the Kruskal-Wallis test, and if the outcome was significant, the Mann-Whitney test. Results: The highest mean Bax and Caspase-3 expression was found in PBS injected and enucleated at day 7 group (G2), 0.96{\textpm}0.40 and 0.72 {\textpm} 0.30, respectively. When compared to PBS injection, the expression of Bax and Caspase-3 was lower in the resveratrol-injected group. Conclusion: Bax and Caspase-3 expressions were lower in the intravitreal injection of Resveratrol in the dose of 100 {\textmu}M following the I-R injury group compared to the group without intravitreal Resveratrol injection.
