Clinical Characteristics and Severity Distribution of Tertiary Eye Center Attendance by Ocular Chemical Injury Patients
Objectives: To report demographic characteristics, types and grades of injury, regional distribution of injury severity, clinical findings, and long-term results of acute ocular chemical burns. Methods: Medical records of patients with chemical burns between 2010 and 2020 who were admitted to Ege University less than 72 hr after the injury were reviewed. Age, gender, cause of the burn, injury severity, initial and final best-corrected visual acuity, surgical intervention, and complications were recorded. The injury severity was graded according to Dua classification. Results: A total of 104 patients (137 ...

Conjunctival Histopathological Changes in Children With Vitamin D Deficiency
Conclusion: Significant conjunctival histopathological changes occur in children with Vit-D deficiency, and these changes have effects on some tear function–associated clinical findings including the Schirmer-1 test and TBUT measurements.

Visual Outcomes of Patients With Peripheral Ulcerative Keratitis and the Effect of Immunosuppression—A 6-Year Experience in Queensland, Australia
Conclusions: Peripheral ulcerative keratitis poses significant clinical challenges and requires intensive medical treatment, frequently involving systemic immunomodulatory therapy. Surgical treatment is required in a significant minority of cases. Ocular management alongside the use of doxycycline and immunomodulatory therapy in consultation with specialist physicians can optimize visual and systemic outcomes.

Gut Microbiome and Its Influence On Ocular Surface and Ocular Surface Diseases
Abstract: The gut microbiome plays a substantial immunologic and pathophysiologic role in maintaining the health of the host, and dysregulation of this dynamic ecosystem has been associated with several inflammatory conditions. Many studies have explored the influence of gut microbiota on the ocular surface and whether gut microbiota impact the pathophysiology of ophthalmic conditions. These findings have highlighted the advantages of enhancing gut microbes through probiotics, prebiotics, diet, vitamin supplementations, and fecal microbial transplant in clinical practice. The purpose of this review article was to provi...

Clinical Profile and Treatment Outcomes of Patients With Acremonium Species Positive Keratitis Managed in a Tertiary Eye Care Center
Conclusion: Acremonium keratitis has a long and indolent course. A prolonged combination therapy of natamycin and voriconazole seems to be effective in the management. A delay in the diagnosis of Acremonium keratitis often leads to clinical worsening requiring keratoplasty. (Source: Eye and Contact Lens: Science and Clinical Practice)

Microorganisms and Antibiotic Resistance of Bacterial Keratitis at a Rural County Hospital in Seville
Conclusions: A high resistance rate to aminoglycosides and fluoroquinolones was observed in gram-positive bacteria. We concluded that fluoroquinolones or aminoglycosides may not be suitable for initial monotherapy in patients with severe bacterial keratitis.

Comparative Analysis of the Clinical Outcomes of Mix-and-Match Implantation of an Extended Depth-of-Focus and a Diffractive Bifocal Intraocular Lens
Conclusion: Mix-and-match implantation of a diffractive bifocal IOL with an EDOF-IOL provides an excellent range of vision, and high levels of contrast sensitivity and patient satisfaction. (Source: Eye and Contact Lens: Science and Clinical Practice)

Severe Corneal Edema Increases ECL From Grafts After DSAEK—Corneal Edema and ECL After DSAEK
Objectives: To determine the relationship between the preoperative degree of corneal edema in the recipient and the endothelial cell density in grafts after Descemet stripping automated endothelial keratoplasty (DSAEK). Methods: This retrospective case series enrolled 111 eyes of 107 patients who underwent DSAEK. The preoperative and postoperative central corneal thickness (CCT) was measured by anterior-segment optical coherence tomography. Eyes were divided into three groups according to the preoperative recipient CCT: group A (mild edema): 550 μm (Source: Eye and Contact Lens: Science and Clinical Practice)

Analysis of Corneal Scheimpflug Densitometry and Ocular Wavefront Aberrations Post Descemet Stripping Automated Endothelial Keratoplasty
Conclusion: There was an inverse relationship between post DSAEK BCVA and total corneal HOAs and full-thickness densitometry at 6 months. Scheimpflug imaging with added tools for corneal aberration and densitometry analysis gives further insight into the suboptimal vision achieved despite transparent corneas post DSAEK.

Influence of Posterior Corneal Asphericity On Power Calculation Error After Laser In Situ Keratomileusis or Photorefractive Keratectomy for Myopia
Objectives: To assess the impact of posterior corneal asphericity on postoperative calculation error using the Haigis-L and the Barrett formulas for eyes after laser in situ keratomileusis or photorefractive keratectomy (PRK). Methods: We assessed the mean absolute error (MAE) of two power calculation formulas, Barrett true-K and Haigis-L formulas, in a retrospective analysis of 34 eyes of 34 patients who underwent cataract surgery. We performed a regression analysis between corneal parameters (anterior and posterior Q values, Kmax, K1, and K2) and the MAE of each formula. Results: In the cohort, 11 eyes ...

Thygeson Superficial Punctate Keratitis: A Clinical and Immunologic Review
Abstract: Thygeson superficial punctate keratitis (TSPK) is clinically characterized by exacerbations and remissions of gray–white opacities within the corneal epithelium, most often bilateral but may be asymmetric. Symptoms typically include photophobia, tearing, blurring, and eye irritation. Although disease progression and prognosis are well described, the exact cause is unknown. Hypotheses exist implicating virus-mediated immunity as the cause of TSPK following cases of viral keratitis; however, several polymerase chain reaction studies refute the infectious process concurrently with symptomatic TSPK. This is fur...

The Protective Effects of Soft Contact Lenses for Contact Sports: A Novel Porcine Model for Corneal Abrasion Biomechanics
Conclusion: The force required to create corneal abrasions varies depending on the angle of the force vector. The use of contact lenses can withstand a minimum of five times the average force needed to create corneal abrasions. (Source: Eye and Contact Lens: Science and Clinical Practice)
