To investigate the efficacy of Wharton's jelly mesenchymal stem cells (WJSCs) and their conditioned medium (CM) for corneal nerve regeneration in rats with diabetic keratopathy. Streptozotocin (STZ)-induced male diabetic (DM) rats (250-300 g) were divided into four groups (n=7/group): Control, DM, DM with WJSCs (DM+WJ), and DM with CM treatment (DM+CM). DM+WJ and DM+CM group received WJSCs or CM, respectively, topically with eye drops. Corneal sensibility, corneal epithelial layer integrity, histology, expression of GAP-43 and TUBB3 on mRNA level and their immunohistochemical expression were examined after two weeks of treatment. There were changes in corneal sensibility and corneal integrity between normal control and diabetic groups with/without WJSC or CM injection. Total central corneal thickness was significantly higher in DM+CM (249.81 ± 43.85 μm) than in control (174.72 ± 44.12 μm, P=0.004) and DM groups (190.15 ± 9.63 μm, P=0.03). GAP-43 mRNA expression levels of DM+WJ and DM+CM groups were higher compared with DM and control groups. TUBB3 mRNA level was increased after CM (P=0.047), but not after WJSCs treatment (P=1.00). GAP-43 and TUBB3 immunohistochemical expression of nerve fibers along the epithelial layer significantly increased in DM+WJ and DM+CM compared with DM group. Our findings showed that WJSCs and their CM improved corneal nerve regeneration in rats with diabetic keratopathy.

Analysis of choroidal thickness, macular thickness, peripapillary retinal nerve fiber layer thickness, and macular vascular density in children with unilateral amblyopia using swept-source optical coherence tomography and their changes following occlusion therapy.
Taiwan J Ophthalmol

Department of Vitreo-Retina, Sankara Eye Hospital, Shimoga, Karnataka, India.
Purpose: The purpose of this study was to analyze choroidal thickness (CT), along with macular thickness (MT), peripapillary retinal nerve fiber layer thickness (RNFLT), and macular vascular density (MVD) using swept-source optical coherence tomography (SS-OCT) in children with unilateral amblyopia, and compare the same with normal fellow eyes and normal eyes of normal children before and following occlusion therapy.
Materials And Methods: This was a prospective, longitudinal study of 60 children (4-18 years); 30 children had unilateral amblyopia and remaining 30 were normal. Group 1 consisted of 30 amblyopic eyes of children with unilateral amblyopia; Group 2 consisted of 30 fellow normal eyes of Group 1; Group 3 consisted of normal eyes of normal children.
Visually significant ocular decompression retinopathy following laser peripheral iridotomy in a patient with primary acute angle-closure glaucoma.

Department of Ophthalmology, Ross Eye Institute, University at Buffalo, 1176 Main Street, Buffalo, NY, 14209, United States.
Purpose: We report a single case of ocular decompression retinopathy (ODR) following neodymium-doped yttrium aluminum garnet laser peripheral iridotomy (Nd:YAG LPI) for primary acute angle-closure glaucoma associated with delayed visual recovery secondary to optic nerve head edema and macular thickening.
Observations: A 56-year-old female patient presented to the emergency department with primary acute angle-closure glaucoma. After topical and IV therapy did not improve intraocular pressure (IOP), an Nd:YAG LPI was performed.
Evaluation of Ocular Irritation Sensitivity: Implications of Clinical Parameters, Pain Sensitivity, and Tear Neuromediator Profiles.

Sensitivity to ocular irritation varies among individuals, being influenced by clinical, subjective, and biochemical factors. This study aimed to evaluate individual variability in ocular irritation sensitivity, focusing on clinical parameters, pain perception, and tear neuromediator profiles. Sixty female participants aged 20-40 were classified into high-sensitivity and low-sensitivity groups based on their response to an irritant (Tween20).

Objective: To report ocular examination findings before and after total ear canal ablation and lateral bulla osteotomy (TECALBO) and ventral bulla osteotomy (VBO) in cats and dogs.
Methods: At The Ohio State University and MedVet Columbus, ophthalmic examinations were performed on client-owned animals for which a TECALBO or VBO was indicated. Examination findings and postoperative complications relating to ophthalmic and/or neuro-ophthalmic diseases were recorded prior to surgery (T0) and at 1 day (T1), 2 to 3 weeks (T14), and ± 2 months (T60) postoperatively.

Significance: In an aging population, the number of people living with neurodegenerative disease is projected to increase. It is vital to develop reliable, noninvasive biomarkers to detect disease onset and monitor progression, and there is a growing body of research into the ocular surface as a potential source of such biomarkers.
Background: This article reviews the potential of in vivo corneal confocal microscopy and tear fluid analysis as tools for biomarker development.
