Abstract
PURPOSE To describe four Finnish families with epithelial recurrent erosion dystrophy (ERED) caused by the pathogenic variant c.3156C>T in collagen type XVII alpha 1 chain gene (COL17A1). METHODS Eleven affected and two unaffected individuals underwent clinical ophthalmological examination, anterior segment photography, and corneal topography. Two of them underwent phototherapeutic keratectomy (PTK). Genetic analysis included both next-generation and Sanger sequencing. Specimens from the manual keratectomy of one patient were available for ophthalmic pathologic examination, including immunohistochemistry. RESULTS The common splice-site altering synonymous variant c.3156C > T, p.(Gly1052=) in COL17A1 was confirmed in 15 individuals with ERED from the four families. Subepithelial corneal scarring grades varied and increased with age, leading to decreased best-corrected visual acuity. PTK improved vision in 58- and 67-year-old individuals without reactivating the disease. The keratectomy specimens showed an uneven epithelium and a spectrum of basement membrane abnormalities, including breaks, fragmentation, multiplication and entrapment within the subepithelial scar, reflecting recurrent erosions. The stromal cells consisted of varying proportions of bland and activated fibroblasts and myofibroblasts, reflecting different ages of scars. The family with the largest number of known affected generations originated from Southern Sweden. CONCLUSION The phenotype in the Finnish ERED families is consistent with earlier reports of the c.3156C > T variant, although the severity has varied between reports. The phenotype may be modulated by other genes. This study suggests a likely founder effect of the variant in both Finnish and Swedish populations due to their shared population histories. If vision is compromised, PTK can be considered especially in older patients.

Abstract
Background: Insulin and insulin-like growth factor (IGF)-1 receptors are present in ocular tissues such as corneal epithelium, keratocytes, and conjunctival cells. Insulin plays a crucial role in the growth, differentiation, and proliferation of corneal epithelial cells, as well as in wound healing processes in various tissues. Purpose: This review explores the potential role of topical insulin in the treatment of ocular surface diseases. Specifically, it examines its impact on corneal nerve regeneration, sub-basal plexus corneal nerves, and its application in conditions like corneal epithelial defects, dry eye disease, and diabetic keratopathy. Methods: The review analyzes studies conducted over the past decade that have investigated the use of topical insulin in ocular surface diseases. It focuses on indications, drug preparation methods, side effects, efficacy outcomes, and variations in insulin concentrations and dosages used. Results: While off-label use of topical insulin has shown promising results in refractory corneal epithelial defects, its efficacy in dry eye disease is yet to be demonstrated. Variations in concentrations, dilutions, and dosing guidelines have been reported. However, limited data on ocular penetration, ocular toxicity, and systemic side effects pose challenges to its widespread utility. Conclusion: This review synthesizes findings from ocular investigations on topical insulin to assess its potential applicability in treating ocular surface and corneal diseases. By highlighting indications, preparation methods, side effects, and efficacy outcomes, it aims to provide insights into the current status and future prospects of using topical insulin in ophthalmic practice.

Abstract
In recent years, among artificial tear preparations that have additional metabolic properties, in addition to moisturizing the ocular surface, there has been a drug Optinol Soft Recovery (LLC JADRAN). In addition to 0.15% sodium hyaluronate, it contains 2% dexpanthenol, which stimulates reparative regeneration of the corneal epithelium, in particular in patients with dry eye syndrome (DES). PURPOSE This study evaluates the clinical efficacy of the drug Optinol Soft Recovery in the treatment of patients with DES accompanied by xerotic changes in the corneal epithelium. MATERIAL AND METHODS The study included 82 patients (15 children and 65 adults) with moderate and severe DES accompanied by the following corneal pathology: filamentous keratitis (20 patients, 33 eyes), persistent corneal erosion (28 patients, 49 eyes) and punctate keratopathy (34 patients, 68 eyes). RESULTS All patients receiving fourfold instillations of the studied drug were observed already during the first 7 days to have increased stability of the tear film and decreased severity of staining of the cornea and conjunctiva with vital dyes (0.1% sodium fluorescein and 3% lissamine green, respectively). Further, as the patients were transferred to an individual instillation regimen, a progressive decrease in the Ocular Surface Disease Index (OSDI), an increase in corneal sensitivity and tear meniscus index were also recorded. The differences in most parameters of the course of xerosis compared to the initial ones were statistically significant starting from day 10-20 of therapy, depending on the initial severity of corneal xerosis (p<0.05-0.001). CONCLUSION Patients with moderate DES complicated by punctate keratopathy were the most susceptible to therapy with the drug Optinol Soft Recovery, while patients with filamentous keratitis secondary to a severe clinical form of DES were the least susceptible.

Abstract
Systemic lupus erythematosus (SLE) potentially involves multiple parts of the ocular system, including the lacrimal glands and the cornea. The present study sought to assess the risk of aqueous-deficient dry eye disease (DED) and corneal surface damage in patients with SLE. We conducted a population-based cohort study using Taiwan's National Health Insurance research database to compare the risks of DED and corneal surface damage between subjects with and without SLE. Proportional hazard regression analyses were used to calculate the adjusted hazard ratio (aHR) and 95% confidence interval (CI) for the study outcomes. The propensity score matching procedure generated 5083 matched pairs with 78,817 person-years of follow-up for analyses. The incidence of DED was 31.90 and 7.66 per 1000 person-years in patients with and without SLE, respectively. After adjusting for covariates, SLE was significantly associated with DED (aHR: 3.30, 95% CI: 2.88-3.78, p < 0.0001) and secondary Sjögren's syndrome (aHR: 9.03, 95% CI: 6.86-11.88, p < 0.0001). Subgroup analyses demonstrated that the increased risk of DED was augmented among patients with age < 65 years and female sex. In addition, patients with SLE had a higher risk of corneal surface damage (aHR: 1.81, 95% CI: 1.35-2.41, p < 0.0001) compared to control subjects, including recurrent corneal erosion (aHR: 2.98, 95% CI: 1.63-5.46, p = 0.0004) and corneal scar (aHR: 2.23, 95% CI: 1.08-4.61, p = 0.0302). In this 12-year nationwide cohort study, we found that SLE was associated with increased risks of DED and corneal surface damage. Regular ophthalmology surveillance should be considered to prevent sight-threatening sequelae among patients with SLE.

Abstract
Rheumatoid arthritis is potentially connected to ocular disorders, such as corneal inflammation and lacrimal gland destruction. This study aimed to evaluate the risk of dry eye disease (DED) and corneal surface damage among patients with rheumatoid arthritis. In a nationwide cohort study, we utilized Taiwan’s National Health Insurance research database and conducted propensity score matching to compare the risks of DED and corneal surface damage between patients with and without rheumatoid arthritis. Proportional hazards regression analyses were used to calculate the adjusted hazard ratio (aHR) and 95% confidence interval (CI) for the outcomes of interest. The matching procedure generated 33,398 matched pairs with 501,377 person-years of follow-up for analyses. The incidence of DED was 23.14 and 10.25 per 1000 person-years in patients with and without rheumatoid arthritis, respectively. After adjusting for covariates, rheumatoid arthritis was significantly associated with DED (aHR: 2.03, 95% CI: 1.93−2.13, p < 0.0001). The association was generally consistent across the subgroups of age, sex, use of systemic corticosteroids, and different comorbidity levels. In addition, patients with rheumatoid arthritis had a higher risk of corneal surface damage (aHR: 1.36, 95% CI: 1.21−1.51, p < 0.0001) compared to control subjects. Other independent factors for corneal surface damage were age and sleeping disorders. Rheumatoid arthritis was associated with an increased risk of DED and corneal surface damage. Ophthalmological surveillance is required to prevent vision-threatening complications in this susceptible population.

Abstract
Persistent corneal graft erosion or persistent epithelial corneal defect is a frequent complication of penetrating keratoplasty. Its development can be contributed by the dry eye syndrome, rare blinking, lagophthalmos, symblepharon, viral infection, autoimmune aggression, and the use of epithelial-toxic eye drops. The article presents three clinical observations of patients who developed persistent corneal graft erosion after penetrating keratoplasty. Due to the ineffectiveness of local conservative therapy for more than 3 weeks, anterior stromal corneal micropuncture was performed. After the procedure, there was a gradual epithelial proliferation, complete healing of the corneal surface was observed 10-16 days after the manipulation, the follow-up period was at least 1 year. The mechanism of action of stromal micropuncture is associated with the creation of a porous surface with better adhesion properties, as well as with the activation of the production of extracellular matrix glycoproteins such as fibronectin, type IV collagen and laminin, which are necessary for stable adhesion of the epithelium. The use of stromal micropuncture of the donor flap in the treatment of post-keratoplasty persistent corneal epithelial defect was proposed for the first time.

Abstract
Changes in the biochemical composition of the tear film is a critical risk factor for the development of chronic perioperative dry eye syndrome, because increasing the duration of general anesthesia did not affect the dynamics of tear secretion recovery, but slowed down normalization of its structure and antioxidant activity in the post-anesthetic period.

Abstract
BACKGROUND/AIMS To assess the prevalence, clinical features and risk factors of lower lid epiblepharon among patients with congenital glaucoma. METHODS Cross-sectional, observational, case-control study. Patients diagnosed with congenital glaucoma between August 1999 and November 2014 were included. Demographic and clinical characteristic data were collected. Age-matched normal controls were recruited form general population. Main outcome measures were the prevalence, laterality and factors associated with epiblepharon in patients with congenital glaucoma. RESULTS The prevalence of lower lid epiblepharon was higher in patients with congenital glaucoma compared with control group (40.7% vs 13.3%, p<0.001). Unilateral epiblepharon was only shown in patients with congenital glaucoma (47.8% vs 0.0%, p<0.001). Multivariate analysis revealed that high intraocular pressure (IOP) at glaucoma diagnosis (OR=1.122), presence of corneal erosion (OR=82.664) and presence of buphthalmos (OR=12.600) were significantly associated with the presence of lower lid epiblepharon. In addition, unilateral epiblepharon was associated with unilateral buphthalmos and unilateral glaucoma (OR of 49.849 and 7.338, respectively). CONCLUSIONS The prevalence of epiblepharon was higher in patients with congenital glaucoma compared with age-matched general population. In patients with congenital glaucoma, epiblepharon was associated with corneal erosions. In addition, buphthalmos and initial high IOP were associated with the development of lower lid epiblepharon. More importantly, unilateral buphthalmos was also significantly associated with unilateral epiblepharon. Therefore, in patients with congenital glaucoma, presence of epiblepharon should be evaluated especially in patients accompanying buphthalmos or corneal erosion.

Abstract
Acute vision loss, a painful eye, or a red/pink eye are typical symptoms of an ophthalmic emergency. Ascertain a thorough medical history concerning type, duration, and location of visual loss to point out the etiology of the disease. With simple diagnostic tools the differential diagnosis can be narrowed down even by non-ophthalmologists. This first differential diagnosis shows how urgent the patient has to be referred to an ophthalmologist.

Abstract
Administration of topical rebamipide increases the mucin level of tear film and improves the ocular surface in short break-up time type of dry eye. Lid wiper epitheliopathy (LWE) is a disorder of the marginal conjunctiva of the upper eyelid with dry eye symptoms. LWE may be related to mechanical forces during blinking resulting in inflammation of the ocular surface. Rebamipide also has various anti-inflammatory effects. In this report, we tried treatment with topical rebamipide for two cases of LWE. One case had been treated with sodium hyaluronate ophthalmic solution and diquafosol sodium eye drops by other doctors for several weeks. The other case was not previously treated. In both cases, fluorescein staining of the cornea and lid margin was remarkably improved, ocular symptoms decreased, and tear film break-up times increased with rebamipide eye drops four times daily for 2-3 weeks. Topical rebamipide was effective for corneal and conjunctival disorders in LWE. This drug may provide a novel approach to the treatment of LWE.

Abstract
Rebamipide is an antiulcer agent used to treat gastric ulcer and gastritis. Biological effects of rebamipide include cytoprotection, wound healing, and anti-inflammatory properties that are known to be universal for a variety of tissues in addition to gastrointestinal mucosa. The therapeutic effects of rebamipide eye drops are due to its ability to increase corneal and conjunctival mucin-like substances and improve corneal and conjunctival injury in vivo. In this paper, we report a case of Sjögren’s syndrome with complete disappearance of corneal erosion after administration of rebamipide eye drops. This was observed even though corneal erosion had not improved for 6 months after punctal occlusion surgery. The patient was a 33-year-old female, diagnosed with Sjögren’s syndrome by a salivary gland biopsy. The corneal and conjunctival surfaces were filled with dense erosions, which did not improve with topical drugs. Punctal plugs were applied several times; however, the plugs were repeatedly shed. All four puncta of both eyelids were surgically occluded, and both corneal and conjunctival erosion was clearly improved. However, the erosion in the inferior cornea of both eyes had not improved for 6 months after surgery. We used the newly approved topical rebamipide for treatment of this patient. The corneal erosion gradually improved and completely disappeared 4 weeks after administration of the drug. Dry eye sensation disappeared at the same time. Both membrane-associated mucin and secreted mucin in the ocular surface are thought to be essential for maintenance of the tear film. Induction of mucin from ocular surface epithelium could be an effective treatment in cases of dry eye caused by mucin deficiency. Through its various mechanisms, rebamipide improves ocular surface conditions. To our knowledge, this is the first clinical case report using rebamipide ophthalmic solution. This drug may provide a novel approach to treat drying diseases of the eye.
