Abstract
PURPOSE The aim of this study was to observe the expression of interleukin (IL)-17 and intercellular adhesion molecule (ICAM)-1 in conjunctivochalasis (CCH) and to analyze the correlations between cytokines and the severity of CCH. METHODS Serum samples were collected from 22 patients with CCH and 18 normal controls (NCs). The Ocular Surface Disease Index, tear film break-up time, Schirmer I test, and corneal fluorescein staining were used to evaluate the ocular surface signs and symptoms. The concentrations of IL-17, IL-23, and ICAM-1 in serum and cellular supernatants were measured by enzyme-linked immunosorbent assays, and the gene expression levels of cytokines were measured by a quantitative real-time polymerase chain reaction. The relationships between serum concentrations of IL-17, IL-23, and ICAM-1 with clinical ocular surface parameters in CCH were analyzed using the Spearman correlation analysis. RESULTS The concentrations of IL-17 and ICAM-1 in serum and cellular supernatants of CCH were significantly higher than those of NCs (all P < 0.001). The concentrations of IL-23 in serum and cellular supernatants of CCH showed no significant difference from those of NCs ( P > 0.05). The mRNA expression levels of IL-17 and ICAM-1 in conjunctival fibroblasts of CCH were significantly higher than those of NCs (all P < 0.001). The mRNA expression of IL-23 in conjunctival fibroblasts of CCH was higher than that of NCs, without a significant difference ( P > 0.05). Furthermore, the serum concentrations of IL-17 and ICAM-1 were positively correlated with Ocular Surface Disease Index and fluorescein staining (all P < 0.05), and negatively correlated with break-up time and Schirmer I test of CCH (all P < 0.05). CONCLUSIONS The expression levels of IL-17 and ICAM-1 were significantly increased in CCH serum and associated with the disease severity. We postulate that IL-17 and ICAM-1 may play a role in the pathogenesis of CCH. IL-17 and ICAM-1 antagonists may be a potential treatment option for CCH in the future.

Abstract
To determine the effectiveness of conjunctivoplasty using a modified argon laser photocoagulation method on patients with conjunctivochalasis (CCh). This study included 25 cases of symptomatic inferior CCh. After staining the surface of a redundant conjunctiva using a dark-purple marker, low-energy argon laser photocoagulation (500 μm spot size for 0.5 seconds at power 300 mW) was applied under topical anesthesia for a mean of 80 times. The patients were aged 67.6 ± 7.1 years (mean ± standard deviation). During a mean follow-up period of 7.8 months (range of 6-12 months), the CCh grades of 21 eyes (84%) decreased after laser conjunctivoplasty. Calculated reduction rates of grades 1, 2, and 3 were 90%, 75%, and 67%, respectively. Patient subjective symptoms were improved in 80% of cases. No postoperative complications such as conjunctival scarring or persistent ocular irritation were observed. Our modified argon laser photocoagulation method employs staining the conjunctival surface to increase the thermal laser energy absorbed by the target. This novel technique is simple and effective for treating mild-to-moderate-grade CCh in outpatient clinics.

Abstract
The purpose of this study was to evaluate the differences in subjective symptoms between patients with conjunctivochalasis (CCh) and dry eye (DE), and examine the relationship between subjective symptoms and quality of life (QOL). In 75 eyes of 75 CCh patients and 122 eyes of 122 DE patients, 12 subjective symptoms classified into four groups depending on the mechanisms associated with symptoms (ITF: instability of tear film, IF: increased friction, R: reflex, and DTC: delayed tear clearance) were evaluated by use of a visual analogue scale (VAS). Fifteen items related to DE symptoms and their influence on daily life were evaluated by use of the dry eye-related quality-of-life score (DEQS) questionnaire, with overall degree of QOL impairment calculated as a QOL score. The correlation between the Total VAS score and QOL score were evaluated. Between the CCh and DE patients, significant differences in subjective symptoms were found in eye dryness, pain, tearing sensitivity to light, and heavy eyelids, while tearing was higher in CCh. A significant strong correlation was found between QOL score and Total VAS score, ITF, and IF in CCh patients. The QOL of CCh patients is strongly determined by decreased tear-film stability and increased friction during blinking.

Abstract
Purpose To determine the incidence of non-traumatic subconjunctival hemorrhage (NTSH) in Indian rural population and analyze the associated risk factors. Methods The study included patients diagnosed having subconjunctival hemorrhage (SCH) who attended the out-patient department (OPD) of ophthalmology. Demographic characteristics of subjects included age, gender, medical and ocular history, and location of hemorrhage. Results The incidence rate of NTSH in this study was 3.07 per 1000 patients per year attending OPD. The men to women ratio for NTSH was 1.26 (95% CI). The commonest site of presentation was nasal side (n=36, 51.4%). Right eye (n= 37, 54.3%) was affected more than the left eye (n=28, 40%). The analysis showed 24 patients (34.3%) did not have any etiological factor attributable to SCH. Conjunctivochalasis (CCH) was associated in 15 patients (21.4%). An antiplatelet agent was associated with SCH in 7 patients (10%). Other factors associated with SCH were hypertension, leukemia, and anemia (n=6, 8.6%). Conclusion This study indicates that NTSH occurs in 3 out of 1000 individuals per year in the rural population presenting to the OPD. Nasal conjunctiva was commonly involved. CCH was associated with 15 patients. Use of antiplatelet agents, hypertension and blood disorders are associated with the risk of NTSH. Patients presenting for the first time with NTSH should be screened for systemic etiological factors.

Abstract
OBJECTIVE This study aimed to determine the relationship between clinical symptoms and findings of patients diagnosed with conjunctivochalasis in our clinic and the risk factors reported in the literature, to determine new possible etiological factors, and to compare routine tear assessment methods with novel strip meniscometry in these patients. MATERIALS AND METHODS The study included patients who presented to our clinic between March 2019 and June 2019 and were diagnosed with conjunctivochalasis. The Ocular Surface Disease Index was used to assess ocular surface symptoms. Anterior segment examination included tear break-up time, corneal staining, localization of conjunctivochalasis, and the presence of pinguecula or pterygium. For each patient, tears were measured using both Schirmer and strip meniscometry. Patients with conjunctivochalasis were evaluated as lid-parallel conjunctival folds grade 1, 2, or 3. RESULTS There was a total of 57 participants, including 31 women (54.4%) and 26 men (45.6%). Lid-parallel conjunctival folds grade was found to be statistically significantly associated with dust exposure (p = 0.034). Multiple regression analysis revealed that dust exposure was an independent predictor of being diagnosed with lid-parallel conjunctival folds grade 2 versus lid-parallel conjunctival folds grade 1 (odds ratio = 3.515, p = 0.029). Moreover, Schirmer's test and strip meniscometry results were positively correlated in patients with conjunctivochalasis (r = 0.302 and p = 0.022). CONCLUSION We conclude that external factors are prominent in patients with conjunctivochalasis, especially dust exposure. In addition, strip meniscometry may be preferred as a more practical and noninvasive alternative to investigate dry eye symptoms in patients with conjunctivochalasis.

Abstract
Introduction: The aim of this study was to evaluate conjunctivochalasis (CCH) and its relationship with tear meniscus and tear function in an elderly population. Materials and methods: This prospective, observational study included 144 eyes of 144 patients aged >65 years who were referred to our clinic for various reasons. The patients were separated into group 1 including 64 eyes of 64 patients with CCH and group 2 including 80 eyes of 80 patients without CCH. All patients in both groups underwent a full ophthalmological examination, and the presence of CCH, fluorescein tear break-up time (FTBUT) test, Schirmer test, ocular surface staining (Oxford grading score) and OSDI (Ocular Surface Disease Index) test results were recorded. Measurements of the conjunctivochalasis area (CCHA), tear meniscus height (TMH) and tear meniscus area (TMA) were taken using anterior segment optic coherence tomography (AS-OCT). Results: Group 1 comprised 34 females and 30 males with a mean age of 71.15 ± 12.34 years. Group 2 comprised 43 females and 37 males with a mean age of 68.16 ± 6.05 years (p = 0.122). The CCH rate was 44.4% in all of the examined patients. The OSDI score and the ocular surface staining test were significantly higher (p < 0.05), and the FTBUT, TMH and TMA were significantly lower (p < 0.05) in group 1 than in group 2. The Schirmer I test results were not significantly different between the two groups. Conclusion: The prevalence of CCH is quite high in elderly individuals and may disrupt tear function in these patients.

Abstract
This study investigated the potential role of MAPK signaling pathways in conjunctivochalasis (CCH). Twenty loose conjunctival biopsy samples from 20 CCH and 15 conjunctival biopsy samples from 15 normal controls (CON) were collected. The conjunctival fibroblasts were cultured in vitro. Immunofluorescence, ELISA, Western blot and reverse transcription-polymerase chain reaction (RT-PCR) were used. Our results showed that the expression of p-ERK, p-JNK, and p-p38 in CCH conjunctiva was significantly higher than that in CON group. The expression of p38 MAPK, JNK, and ERK proteins in CCH fibroblasts was significantly higher than that in CON group. The total expression of MAPK mRNA in CCH fibroblasts was significantly higher than that in CON group. The activated forms of p38 MAPK, JNK, and ERK proteins and mRNAs might up-regulate the expression of MMPs in CCH loose conjunctival tissue and fibroblasts, causing the degradation of collagen fibers and elastic fibers and promoting the occurrence of CCH. Our results deepen the understanding of CCH pathological mechanism.

Abstract
AIM To explore a feasible method on the establishment of an animal model of conjunctivochalasis (CCH). METHODS Twelve clean-grade New Zealand white rabbits were divided into four groups (n=3/group): the control group (one received no interventions, and the others underwent subconjunctival injection of sterile water), the matrix metalloproteinases (MMPs) group (administered subconjunctival injection of MMP-3), the aging group (administered subcutaneous injection of D-galactose), the tumor necrosis factor-α (TNF-α) solution group (administered eye drops of TNF-α). Anterior segment photography, conjunctival tissue light microscopy and transmission electron microscopy (TEM) were performed after 12wk. RESULTS Among all groups, the MMPs group had the following changes: the looser connection between the inferior bulbar conjunctiva and sclera; the more disordered collagen fibers (Trichrome staining) and the broken elastic fibers (Aldehyde-fuchsin staining); the focal necrosis of fibroblasts (TEM). CONCLUSION Administration of MMPs may be a feasible method for the establishment of an animal model of CCH.

Abstract
Background: We aimed to investigate the clinical importance of conjunctivochalasis (CCH) and, further, to implement a new CCH classification system. Methods: 60 eyes of patients with whom, upon clinical examination, CCH was diagnosed were investigated for the presence of symptoms and signs characteristic of dry eye. The eyes were grouped based on two stages of severity, Stage 1 (minimal/mild) and Stage 2 (medium/severe), for each nasal, middle, and temporal position, and on the extent of CCH folds in each site. Results: In 40 (66.6%) out of 60 eyes, symptoms and signs of CCH were manifest: pain in 25 (41.6%), epiphora in 25 (41.6%), and lacrimal punctum obstruction from conjunctival folds in 22 (36.6%) eyes. Depending on the position of CCH, a greater percentage of symptoms appeared in Stage 2 in the nasal position (78.9%), followed by middle (68.7%) and temporal positions (60%). When TBUT values were compared, statistically significant differences were found proportional to grading (p < 0.001) and position (nasal more severe than temporal, p < 0.001), and such differences were also found when TBUT values of all eyes were compared with those of symptomatic eyes (p = 0.01) and with those of symptom-free eyes (p = 0.002). Conclusions: CCH is a rather frequent and commonly unrecognized condition that should always be considered in differential diagnoses of dry eye.

Abstract
Conjunctivochalasis (CCH) is a conjunctival condition characterized by loose, redundant conjunctival folds, most typically in the inferior bulbar conjunctiva of both eyes. Although CCH is a common cause of ocular irritation and discomfort, especially in the elderly, it is often overlooked in clinical practice. CCH may be associated with various ocular and nonocular conditions; however, the most important risk factor is aging. Although often asymptomatic, CCH may cause symptoms related to tear film instability and/or delayed tear clearance. Pathogenesis of CCH remains largely unknown but may involve different elements such as aged conjunctiva, unstable tear film, mechanical friction, ocular surface inflammation, and delayed tear clearance. Contradictory results have been reported on histopathologic changes in CCH, with some studies showing a normal microscopic structure. For symptomatic CCH, medical treatment may include lubrication and anti-inflammatory medications. For symptomatic patients who fail to respond to medical treatment, a surgical procedure may be considered. Although various surgical procedures have been used for CCH, more often, it consists of conjunctival cauterization or excision of the redundant conjunctiva, with or without amniotic membrane transplantation.

Abstract
The PubMed, MEDLINE databases and China National Knowledge Infrastructure (CNKI) were searched for information regarding the etiology and pathogenesis of conjunctivochalasis (CCh) and the synthesis and degradation of elastic fibers. After analysis of the literature, we found elastic fibers was a complex protein molecule from the structure and composition; the degradation of elastic fibers was one of the histopathological features of the disease; the vast majority of the factors related to the pathogenesis of CCh ultimately pointed to abnormal elastic fibers. By reasonably speculating, we considered that abnormal elastic fibers cause the conjunctival relaxation. In conclusion, we hypothesize that elastic fibers play an important role in the pathogenesis of CCh. Studies on the mechanism of synthesis, degradation of elastic fibers are helpful to clarify the pathogenesis of the disease and to find effective treatment methods.

Abstract
AIM To investigate the expression of matrix metalloproteinases 1 and 3 (MMP-1 and MMP-3) and their tissue inhibitors of metalloproteinases 1 and 3 (TIMP-1 and TIMP-3) in the conjunctiva of eyes with conjunctivochalasis (CCh). METHODS The conjunctival tissue was obtained from the CCh patients and controls, the MMPs/TIMPs expression concentration was determined by enzyme-linked immuno-sorbent assay (ELISA) and immunofluorescence staining. The expression levels of MMPs/TIMPs in the CCh fibro-blasts were determined by analyzing its concentration in the cellular supernatant that was abstracted from the in vitro cultured CCh fibroblasts. RESULTS MMP-1 and MMP-3 levels determined by ELISA were both significantly higher in the CCh group than that in the control group (P=0.042, 0.022, respectively), so was the levels of TIMP-1 (P=0.010). No significant difference in the expression of TIMP-3 in conjunctiva was found between the two groups (P=0.298). The expression of MMP-1 and MMP-3 were both up-regulated significantly in the CCh group (P=0.040, 0.001, respectively) on immuno-fluorescence staining. MMP-1 and MMP-3 expression in the fibroblasts were both significantly higher in the CCh group than that in the control group (P=0.027, 0.001, respectively), while neither the TIMP-1 nor TIMP-3 expression was significantly different between the two groups (P=0.421, 0.237, respectively). CONCLUSION The overexpression of MMP-1 and MMP-3 in conjunctival tissue and fibroblasts may play an important role in the pathogenesis and development of CCh.
