Article Abstract
Purpose: To report the intraoperative performance and postoperative outcomes in microphthalmic eyes of infants younger than 1 year having bilateral cataract surgery.
Setting: Iladevi Cataract & IOL Research Centre, Ahmedabad, India.
Methods: This prospective observational study excluded eyes with ocular trauma, inflammation, posterior persistent fetal vasculature causing stretching of the ciliary processes or tractional retinal detachment, aniridia, or chorioretinal coloboma. Intraoperative observations included the rate of peripheral extension of the anterior capsule tear, intraoperative iris prolapse/trauma, and posterior capsule tear. All eyes were left aphakic. Postoperative observations included visual outcome, posterior synechias, visual axis obscuration (VAO), and glaucoma.
Results: The study evaluated 42 eyes of 21 infants. The mean age at surgery was 4.0 months +/- 2.6 (SD) and the mean follow-up, 25.6 +/-11.3 months. Surgery was performed using the limbal approach in 30 eyes (71.4%) and by pars plicata lensectomy in 12 eyes (28.6%). In the limbal group, 3 eyes (10.0%) had an incomplete anterior capsulorhexis, 2 eyes (6.7%) had iris trauma, and 2 eyes (6.7%) had peripheral extension of the posterior capsulectomy edge. At the final follow-up, visual acuity remained stable in 4 eyes (9.5%) and was improved in 38 eyes (90.5%). The complications were posterior synechias in 15 eyes (35.7%), glaucoma in 13 eyes (30.9%), and VAO in 7 eyes (16.7%).
Conclusion: The results suggest that good visual outcomes can be obtained in microphthalmic patients with bilateral congenital cataract after early surgical intervention, with an acceptable rate of serious postoperative complications.

Retinal ganglion cells (RGCs) are highly compartmentalized neurons whose long axons serve as the sole connection between the eye and the brain. In both injury and disease, RGC degeneration occurs in a similarly compartmentalized manner, with distinct molecular and cellular responses in the axonal and somatodendritic regions. The goal of this study was to establish a microfluidic-based platform to investigate RGC compartmentalization in both health and disease states.

Background: Sjögren's syndrome (SS) is a chronic autoimmune disease delineated by excessive lymphocyte infiltration to the lacrimal or salivary glands, leading to dry eye and dry mouth. Exosomes secreted from mesenchymal stem cells (MSC) are known to have anti-inflammatory and tissue regeneration abilities. This study endeavored to demonstrate the effect of MSC-derived exosomes on the clinical parameter of dry eyes and associated pathology in SS mouse model.

Antibody-drug conjugates (ADCs) represent a promising therapeutic approach in gynecologic cancers, particularly ovarian and cervical malignancies. Agents such as mirvetuximab soravtansine, and tisotumab vedotin, targeting folate receptor alpha and tissue factor, respectively, reported clinical efficacy in patients with limited options. However, their use is associated with ocular toxicities, including keratopathy, blurred vision, and dry eye, which may impact adherence and quality of life.

Introduction: The definition of Leber's hereditary optic neuropathy (LHON) does not take into account a preclinical phase during which the thickness of retinal nerve fiber layer (RNFL) is increased, prior to optic nerve atrophy, reducing the chances of visual recovery.
Objectives: Search for a metabolomic signature characterizing this preclinical phase and identify biomarkers predicting the risk of LHON onset.
Methods And Results: The blood and tear metabolomic profiles of 90 asymptomatic LHON mutation carriers followed for one year will be explored as a function of RNFL thickness and compared to those of a healthy control.
