Clinical correlations and impact of conjunctivochalasis in soft contact lens wearers.

PURPOSE: To evaluate the correlation between clinical tests, patient symptoms, and conjunctivochalasis in contact lens wearers and non-wearers. METHODS: This study comprised 40 eyes of 40 current soft contact lens users and 40 eyes of 40 control subjects. Cross-sectional areas of conjunctivochalasis at three locations (nasal, central, temporal) during straight and downward gazes were determined using anterior segment optical coherence tomography in all participants. Tear film break up time test and Schirmer test with anesthesia were performed and for evaluation of symptoms, the participants completed ocular surface disease index questionnaire. RESULTS: During straight gaze, the mean cross-sectional areas of conjunctivochalasis were 0.0112 ± 0.009 and 0.006 ± 0.005 mm2 at nasal, 0.0096 ± 0.007 and 0.002 ± 0.004 mm2 at central, 0.0176 ± 0.014 and 0.008 ± 0.009 mm2 at temporal in contact lens and control groups, respectively. Regardless of location and gaze direction, the mean cross-sectional conjunctivachalasis areas of the contact lens group were significantly higher than those of the controls (all, p < 0.05). Significant positive correlations between ocular surface disease index score and measured conjunctivachalasis areas (in all sites) during straight gaze and downward gaze were observed in the contact lens group (all, p < 0.05 and r > 0.450). CONCLUSION: Wearing soft contact lenses is associated with increased conjunctivochalasis areas. Anterior segment optical coherence tomography determined conjunctivochalasis area is an objective clinical measurement value that is positively correlated with patients' symptoms in soft contact lens wearers.

The Influence of Lid-Parallel Conjunctival Folds and Conjunctivochalasis on Dry Eye Symptoms with and Without Contact Lens Wear: A Review of the Literature.

INTRODUCTION: Lid-parallel conjunctival folds (LIPCOF) and conjunctivochalasis (CCH) are similar conditions that seem to be related to dry eye severity. In addition, there is a lack of studies on the topic of LIPCOF and CCH on dry eye symptoms in non-contact lens and contact lens (CL) wearers. Therefore, the aim of this study is to review the relationship of LIPCOF and CCH with dry eye symptoms in non-CL and CL wearers, as well as to report the treatment of dry eye disease (DED) in non-CL and CL wearers who present LIPCOF or CCH. METHODS: A literature review of full-length original studies in two databases, PubMed and Scopus, was performed. The search period included observational studies in humans published between April 21, 2009 and March 20, 2023. RESULTS: A total of 26 studies were included. The studies suggest that LIPCOF and CCH are significantly related to dry eye symptoms in non-CL and CL wearers. However, the impact of CL wear on LIPCOF and CCH may be complex and may vary depending on individual factors such as lens type, lens care regimen, and pre-existing ocular conditions. Regarding LIPCOF management, tear substitutes seem to significantly reduce LIPCOF and dry eye symptoms in non-CL wearers, while vectored thermal pulsation (VTP) and microblepharoexfoliation (MBE) are suggested as promising treatment for LIPCOF and dry eye symptoms in CL wearers. Regarding CCH management, surgical interventions may be effective in reducing CCH when medical treatments have no response. In addition, an ocular examination by slit lamp is necessary to distinguish both conditions. CONCLUSIONS: Tear substitutes, VTP, MBE, and fitting CLs with low coefficient of friction (CoF) seem to reduce and prevent LIPCOF. However, surgical treatment options seem to be more effective in the complete elimination of CCH. An adequate evaluation and differentiation between LIPCOF and CCH are important, and they should be considered by practitioners in managing dry eye symptoms in non-CL and CL wearers.

Tenon excision with fibrin glue-assisted reattachment of conjunctiva flap (T.E.F.A.R.C) for the treatment of conjunctivochalasis.

To observe the surgical outcome of "Tenon Excision with Fibrin Glue-Assisted Reattachment of Conjunctiva Flap" (T.E.F.A.R.C.) for the treatment of symptomatic conjunctivochalasis (CCH). This is a retrospective case series of CCH patients undergoing T.E.F.A.R.C. from January 2017 to December 2020 were reviewed. Seven patients (14 eyes) with symptomatic CCH received T.E.F.A.R.C. in both eyes. The symptoms before and after the procedures were compared and surgical complication was evaluated. The mean follow-up time was 13.7 ± 2.14 months. After the operation, resolution of the symptoms was reported in 12 eyes (86%). The grade of CCH decreased from 3 to 0 in all 14 eyes, and the restoration of inferior conjunctival surface and fornix within 1 day was also observed in all eyes. Most patients had localized injection and mild chemosis after the operation, which mostly recovered within 3 weeks. No complication or recurrence of CCH was reported after 1 year of follow-up. In conclusion, T.E.F.A.R.C. is a simple and effective treatment option for CCH with less surgical complication. Future larger studies are needed to confirm its clinical applicability.

The mechanism of Qijing Mingmu decoction on cellular senescence of conjunctivochalasis.

BACKGROUND: Qijing Mingmu decoction (QJMM), a compound Chinese medicine preparation, which consists of Lycium barbarum, Polygonatum, Ophiopogon japonicus, Poria cocos, Glycyrrhiza, Eclipta prostrata and Ligusticum striatum, has been confirmed to be effective for the treatment of conjunctivochalasis (CCH) in clinic and reduce cellular senescence. However, the underlying mechanism is still unknown. Our previous study revealed that p38-mediated cellular senescence contributed to the pathogenesis of CCH. METHODS: To explore whether p38 might be the potential therapeutic target of QJMM for CCH, CCH fibroblasts were treated with QJMM granule and then the effect of QJMM granule on the expression and promoter activity of p38α was determined by western blot and dual luciferase reporter gene assay, respectively. Meanwhile, the influence of QJMM granule on cell proliferation, oxidative stress, cellular senescence and the expression of the cellular senescence-associated genes were measured by corresponding methods. RESULTS: QJMM granule significantly decreased the protein expression of p38α and p-p38α in CCH fibroblasts in a dose-dependent manner and inhibited p38α promoter activity. QJMM granule as well as the p38 inhibitor SB203580 reduced the level of reactive oxygen species and increased the activity of superoxide dismutase in CCH fibroblasts. QJMM granule and SB203580 promoted cell proliferation and reduced the percentage of SA-ß-Gal-positive cells. The mRNA and protein expression of p53 and p21 was remarkably down-regulated by QJMM granule as well as SB203580 and that of SMP30 was up-regulated in CCH fibroblasts. CONCLUSIONS: Our findings demonstrated that QJMM granule was effective for alleviating cellular senescence of CCH fibroblasts by p38 MAPK signaling and the followed p53/p21 signaling.

Fornix deepening reconstruction in conjunctivochalasis surgery.

PURPOSE: To assess the extent of inferior fornix shortening in conjunctivochalasis (CCh) and to evaluate whether fornix deepening reconstruction can restore the fornix tear reservoir in patients with CCh. MATERIALS AND METHODS: This was a retrospective review of five patients (3 unilateral and 2 bilateral eyes, total 7 eyes) with CCh who underwent fornix deepening reconstruction with conjunctival recession and amniotic membrane transplantation. Postsurgical outcome measures included changes in fornix depth with correlation to basal tear volumes, symptoms, corneal staining, and conjunctival inflammation. RESULTS: For the three patients with unilateral surgery, both the fornix depth (8.3 ± 1.5 mm) and wetting length (9.3 ± 8.5 mm) of the operative eyes were less than the fellow eyes (10.3 ± 1.5 mm and 10.3 ± 8.5 mm, respectively). At 5.3 ± 2.7 months (range 1.7-8.7) postoperatively, the fornix depth increased significantly by 2.0 ± 1.1 mm (P = 0.02). Deepening of the fornix depth was accompanied by overwhelming symptomatic relief (91.5%) that could be subdivided into complete relief (87.5%) and partial relief (4%) of symptoms, with blurred vision being the most notably relieved symptom (P = 0.03). Furthermore, superficial punctate keratitis and conjunctival inflammation were significantly improved at follow-up (P = 0.008 and 0.05, respectively). CONCLUSION: Deepening of the fornix to restore the tear reservoir is an important surgical objective that may change the tear hydrodynamic state to provide a stable tear film and improve outcomes in CCh.

Preliminary study on the efficacy of lacrimal duct reconstruction with pedicled conjunctival flap in the treatment of severe lacrimal canalicular obstruction with conjunctivochalasis.

AIM: To determine the efficacy and safety of pedicled conjunctival lacrimal duct reconstruction in the treatment of severe obstruction of superior and inferior lacrimal canaliculi with conjunctivochalasis. METHODS: This study was performed as a retrospective analysis of patients who received conjunctival dacryocystorhinostomy with pedicled conjunctival flap reconstruction combined with tube intubation due to severe superior and inferior lacrimal canalicular obstruction with conjunctivochalasis from January 2019 to October 2019. The clinical data included the degree of preoperative epiphora and postoperative relief, preoperative examination of lacrimal duct computed tomography and ultrasound biomicroscopy, postoperative evaluation of lacrimal duct function by chloramphenicol taste and fluorescein dye disappearance test, etc. Syringing was carried out to determine the reconstruction and patency of the lacrimal duct. RESULTS: All 9 patients (9 eyes) had severe canalicular obstruction with conjunctivochalasis. The patients included 4 males and 5 females aged between 47-65y with an average age of 52.2±6.7y. At 3mo follow-up, the tube was removed and the patients were followed for a further 3mo. After tube removal, 6 patients showed no epiphora. These patients also had positive chloramphenicol tastes and normal fluorescein dye disappearance test results. Two patientshad epiphora. Also, syringing showed partial patency of the reconstructed lacrimal duct. One patient had no improvement in epiphora with negative chloramphenicol taste and fluorescein dye disappearance test results and obstruction of the reconstructed lacrimal duct. The total effective rate of the operation was 8/9, with no serious complications. CONCLUSION: Pedicled conjunctival lacrimal duct reconstruction conjunctival dacryocystorhinostomy is safe and effective for superior and inferior canalicular obstruction with conjunctivochalasis.

Comparison of Efficacy and Inflammatory Response to Thermoconjunctivoplasty Performed with Cautery or Pulsed 1460 nm Laser.

Conjunctivochalasis is a degenerative condition of the conjunctiva that disrupts tear distribution and causes irritation. Thermoreduction of the redundant conjunctiva is required if symptoms are not relieved with medical therapy. Near-infrared laser treatment is a more controlled method to shrink the conjunctiva than thermocautery. This study compared tissue shrinkage, histology, and postoperative inflammation in thermoconjunctivoplasty performed on the mouse conjunctiva using either thermocautery or pulsed 1460 nm near-infrared laser irradiation. Three sets of experiments were performed on female C57BL/6J mice (n = 72, 26 per treatment group and 20 control) to assess conjunctival shrinkage, wound histology, and inflammation 3 and 10 days after treatment. Both treatments effectively shrunk the conjunctiva, but thermocautery caused greater epithelial damage. Thermocautery caused greater infiltration of neutrophils on day 3 and neutrophils and CD11b+ myeloid cells on day 10. The thermocautery group had significantly higher conjunctival expression of IL-1ß on day 3. Expression of chemokine CCL2 was higher in the conjunctiva on day 3 and tear concentrations were higher on day 7 in the laser group. These results suggest that pulsed laser treatment causes less tissue damage and postoperative inflammation than thermocautery while effectively addressing conjunctivochalasis.

Mechanism of Akt regulation of the expression of collagens and MMPs in conjunctivochalasis.

Akt is a central node of many signaling pathways, which plays important roles in cell survival, proliferation, migration, metabolism and collagen synthesis. Conjunctivochalasis (CCH) is one of the most common age-related ocular superficial diseases related to abnormalities in conjunctival extracellular matrix. Here, we studied the role of Akt regulating collagens and MMPs in the pathogenesis of CCH. Primary conjunctival fibroblasts were obtained from CCH patients (n = 13) and age-matched normal controls (n = 10). The levels of Akt, collagen type I, collagen type III, MMP1, and MMP3 were determined by Western blot, qRT-PCR, immunohistochemistry, and immunofluorescence staining. Normal control conjunctival fibroblasts were treated with Akt inhibitor A6730, and CCH fibroblasts were transfected with Akt overexpression vector. The expression of Akt in CCH was significantly lower than that in normal control of conjunctival tissues and cultured fibroblasts. Blocking Akt signaling with Akt inhibitor could inhibit the expression of collagen type I and collagen type III and upregulate the expression of MMP1 and MMP3. Meanwhile, compared with CCH fibroblasts transfected with control mimics, the protein and mRNA expression of collagen type I and collagen type III were increased significantly in Akt overexpression group, while the results of MMP1 and MMP3 in transfected fibroblasts were opposite. Taken together, Akt upregulated the expression of collagen type I and collagen type III and downregulated the expression of MMP1 and MMP3. Akt signaling pathway could provide a direct negative contribution to CCH and might be an attractive target for CCH therapy.

Qi Jing Mingmu decoction inhibits the p38 signaling pathway in conjunctivochalasis fibroblasts by down-regulation of Th17 cell differentiation.

ETHNOPHARMACOLOGICAL RELEVANCE: Qi Jing Mingmu (QJMM) decoction is a traditional Chinese medicine that has been widely used for the clinical treatment of conjunctivochalasis (CCH). It is an effective treatment to relieve ocular symptoms including improving tear film and promoting tear secretion. However, its effects and molecular mechanisms need to be elucidated. AIM OF THE STUDY: To determine whether QJMM decoction affected T helper 17 (Th17) cell differentiation of CCH patients. MATERIALS AND METHODS: Blood samples and conjunctival tissues were collected from CCH patients and normal controls. The fibroblasts were separately induced, and CD4+ T cells were incubated with increasing concentrations of QJMM decoction and co-cultured with CCH fibroblasts. Th17 cell numbers were then analyzed using flow cytometry. Serum levels of interleukin 17 (IL-17) and IL-22 were detected using enzyme-linked immunosorbent assays. The expressions of signal proteins and genes were detected using western blotting and quantitative real-time PCR. RESULTS: Compared with normal controls, Th17 cell numbers and serum levels of IL-17 and IL-22 were elevated in patients with CCH. QJMM decoction down-regulated the expressions of IL-17, IL-22, and STAT3 of CD4+T cells from CCH patients, suggesting that QJMM decoction impeded Th17 cell differentiation. QJMM decoction-treated CD4+ T cells inhibited the expression of p38 in CCH fibroblasts. CONCLUSION: QJMM decoction inhibited Th17 cell differentiation of CD4+T cells from CCH patients, and QJMM decoction-treated CD4+T cells down-regulated the p38 signal pathway in CCH fibroblasts. Our study showed that Th17 cells may be good candidates for clinical treatment of CCH.

Successful reversal of neuropathic eye pain by treatment of occult ocular surface disease: Case series and implications.

Purpose: To report the successful approach to managing neuropathic dry eye-like pain (NP) in three consecutive patients described as severe: 1) "burning fire," "burning acid," and "horrible burning pain" with hyperalgesia and allodynia, 2) refractory to topical anesthetic (TA), and 3) without surface hyperemia nor vital staining. Observations: Two of three patients' pain was reversed with significant symptom relief within 48 hours by identification of occult obstructive Meibomian gland dysfunction (o-MGD) and treatment using Meibomian gland probing (MGP) with intraductal steroid lavage (MGP(s)) and aqueous tear deficiency (ATD) treated with punctal thermocautery (PO). The third patient's pain was reversed within one week after treatment of superior conjunctivochalasis (CCh) using amniotic membrane surface reconstruction and ATD using PO with subsequent MGP and MGP(s) for o-MGD. Conclusions and importance: It has been generally thought that central (NP) is strongly suggested by triad of 1) severe chronic burning pain with hyperalgesia and allodynia, 2) refractory to TA with 3) minimal signs. In this three-case series, treatment of occult surface disease consistently led to symptom reversal. Results may represent salutary effect of successful treatment to suppress nociceptive inflammation leading to reversal of central NP. Alternatively, the current triad of diagnostic criteria may be unable to differentiate centralized NP from peripheral sensitization alone, thereby requiring rigorous examination to uncover occult, yet treatable, surface disease to restore eye comfort and reverse psychosocial sequelae when possible. Furthermore, rigorous targeting of surface disease in patients with this pain triad may obviate unnecessary systemic treatments with associated risks of serious side effects.

Does the conjunctivochalasis accompanied by pseudoexfoliation syndrome affect the ocular surface and anterior segment structures?

PURPOSE: The probability of the coexistence of conjunctivochalasis and pseudoexfoliation syndrome (PES) in the same individual may increase with aging. We investigated the effects of conjunctivochalasis accompanied by PES on the ocular surface (OS) and anterior segment (AS) structures. METHODS: Cases with only conjunctivochalasis were determined as Group 1 (n = 62), cases with conjunctivochalasis accompanied by PES as Group 2 (n = 45), and healthy individuals as Group 3 (n = 56). The OS and AS parameters of the groups were compared. RESULTS: There were a higher grade-3 conjunctivochalasis rate (17.7% vs. 46.7%, p = 0.039), a greater "mean grade of conjunctivochalasis" value (1.72 ± 0.24 vs. 2.29 ± 0.32, p = 0.036), and a higher "total conjunctivochalasis score" (4.27 ± 1.13 vs. 6.12 ± 1.35, p = 0.025) in Group 2 than in Group 1. Additionally, Group 2 had a shorter tear film break-up time (TBUT) (9.17 ± 2.53 vs. 5.41 ± 1.32, p = 0.010) and a greater OS disease index (OSDI) score (16.28 ± 3.15 vs. 27.36 ± 4.12, p = 0.037) than Group 1. Moreover, both Group 1 and Group 2 had shorter TBUTs (Group 1-3: p = 0.004; Group 2-3: p < 0.001) and greater OSDI scores (Group 1-3: p = 0.042; Group 2-3: p = 0.019) compared to Group 3. The groups' ocular surface staining scores, Schirmer 1 tests, central corneal thicknesses, keratometries, axial lengths, anterior chamber depths, lens thicknesses, and intraocular pressures were similar (p > 0.05). CONCLUSIONS: To our knowledge, this was the first study comprehensively investigating the effects of conjunctivochalasis accompanied by PES on the OS and AS structures together. We found that conjunctivochalasis might cause the OS disease, while the presence of PES in conjunctivochalasis cases might worsen both the OS disease and conjunctivochalasis findings.

Primary cell culture and morphological observation of bulbar conjunctival fibroblasts in conjunctivochalasis / 国际眼科杂志(Guoji Yanke Zazhi)

AIM: To observe the growth status and morphological changes of primary cultured bulbar conjunctival fibroblasts in different stages of conjunctivochalasis(CCH), and to determine the best passage time, so as to obtain stable and consistent CCH bulbar conjunctival fibroblasts.METHODS: CCH primary bulbar conjunctival fibroblasts were obtained by tissue block adhesion method. The fibroblasts were purified by trypsin differential digestion method. The growth status and morphological changes of fibroblasts in different periods were observed and recorded under inverted microscope. The fibroblasts were identified by immunofluorescence cytochemical staining.RESULTS: After 24h of CCH conjunctival tissue adherent to the wall, a small number of cells would be seen crawling out around the tissue blocks. The logarithmic phase of cell growth was from the 2-7d. The cells grew fast, with vigorously proliferation, clear outline, uniform distribution, increas in numbers and clear nuclei. From the 9-15d, the cell growth entered the plateau stage, the tissue blocks gradually aged and lost activity. The cells grew slowly, arranged loosely, the volume became larger, the shape became flat, and a large number of granular substances and vesicles were produced in the cytoplasm. Some cells fell off from the bottom of the culture bottle, and large gaps appeared between the cells. After subculture and purification, the size and morphology of fibroblasts were basically the same. Through cell identification, fibroblasts were long spindle, flat star or multi-process spindle, wide in the middle, oval nucleus, relatively small at both ends, with 2-3 slender processes of different lengths extending outward.CONCLUSION: Primary CCH bulbar conjunctival fibroblasts can be successfully obtained by tissue block adhesion method. When the cells grow to the 8d, they can be digested and passaged to obtain stable and consistent CCH conjunctival fibroblasts.

Dust exposure: a novel environmental risk factor for conjunctivochalasis?

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.

Impression cytology and meibomian glands in conjunctivochalasis.

PURPOSE: To evaluate the tear parameters, meibomian glands and lid margin and tarsal conjunctival impression cytology in patients with conjunctivochalasis (CCH). METHODS: The study included 57 patients diagnosed with CCH and 35 healthy volunteers. Tear break-up time (TBUT) was measured and Schirmer test was performed. Meibomian gland morphologies, dropout rates, and meiboscores were evaluated using meibography. Finally, impression cytology samples were taken by pressing the impression filters on the lower lid margin and lower tarsal conjunctiva. The samples were evaluated according to the Nelson grading system. RESULTS: Schirmer test was longer and TBUT was shorter in the study group (p = 0.035 and p < 0.001, respectively). The median of meibomian gland dropout rate was 33.45% (Interquartile range [IQR]; 23.17%-49.75%) and 18.80% (IQR; 12.35%-26.50%) in the study and control groups, respectively (p < 0.001). There was no significant difference in terms of lid-margin cytology between the two groups (p = 0.481). In tarsal conjunctiva cytology, the median value of Nelson grade of the study group was 2 (IQR; 1-2) and that of the control group was 1 (IQR; 1-2) (p = 0.040). When Nelson grade-2 and above was accepted as the pathological limit, it was found that 27.5% of the study group and 15.2% of the control group showed pathological findings (p = 0.204). CONCLUSIONS: In patients with CCH, damage occurs in the tarsal conjunctiva with the effects of redundant conjunctival folds. In these patients, atrophy occurs in the meibomian glands and tear stability is impaired. Therefore, CCH should not be overlooked in clinical practice.

Incidence of Non-Traumatic Subconjunctival Hemorrhage in an Indian Rural Population.

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.

The Relationship between Subjective Symptoms and Quality of Life in Conjunctivochalasis Patients.

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.

The effect of conjunctivochalasis detected by anterior segment optical coherence tomography on tear function in an elderly population.

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.

Effects of Qi Jing Mingmu decoction combined with artificial tears on the clinical results and cell aging of conjunctivochalasis / 国际眼科杂志(Guoji Yanke Zazhi)

@#AIM: To observe the effects of Qi Jing Mingmu decoction combined with artificial tears on the clinical results and cell aging of conjunctivochalasis. <p>METHODS: Forty cases(80 eyes)of grade II-Ⅳ CCH with liver-kidney Yin deficiency were randomly divided into two groups: combined treatment group and artificial tears group, which were treated with Qi Jing Mingmu decoction combined with artificial tears and simple artificial tears respectively. The international ocular surface disease index(OSDI), tear break-up time(BUT)and Schirmer Ⅰ test(SⅠt)were observed and the clinical effects were compared after 3mo treatment. For CCH patients with grade III or above, followed up for 3mo or more and willing to operate, the loose conjunctival tissue was removed and the cell aging related β-gal staining was performed on frozen sections. The results were statistically analyzed. <p>RESULTS: The OSDI score(14.53±2.68), BUT 9.25±3.02s and SⅠt(8.95±3.57mm/5min)of combined treatment group were significantly better than those of artificial tears group after 3mo treatment(all <i>P</i><0.05). After drug treatment, 7 cases(7 eyes)in artificial tears group and 4 cases(4 eyes)in combined treatment group of CCH patients were treated by operation. The positive rate of aging cells in combined treatment group was significantly lower than that in artificial tears group(16.00±7.84 <i>vs </i>39.00±14.09, <i>P</i>=0.013).<p>CONCLUSION: Qi Jing Mingmu decoction combined with artificial tears to treat CCH is more effective than simple artificial tears in relieving ocular symptoms, improving tear film and promoting tear secretion. Combined treatment can also reduce the cell aging in CCH, which can be used as a safe and effective treatment method in addition to surgical operation.

The positive rate of aging cells in combined treatment group was significantly lower than that in artificial tears group(16.00±7.84 <i>vs </i>39.00±14.09, <i>P</i>=0.013).<p>CONCLUSION: Qi Jing Mingmu decoction combined with artificial tears to treat CCH is more effective than simple artificial tears in relieving ocular symptoms, improving tear film and promoting tear secretion. Combined treatment can also reduce the cell aging in CCH, which can be used as a safe and effective treatment method in addition to surgical operation.
