Progress in Nanotechnology for Treating Ocular Surface Chemical Injuries: Reflecting on Advances in Ophthalmology.

Ocular surface chemical injuries often result in permanent visual impairment and necessitate complex, long-term treatments. Immediate and extensive irrigation serves as the first-line intervention, followed by various therapeutic protocols applied throughout different stages of the condition. To optimize outcomes, conventional regimens increasingly incorporate biological agents and surgical techniques.

A Sandwich-Like Oral Mucosa Graft-Conjunctiva In Situ-Dermis-Fat Graft for Reconstruction of the Anophthalmic Socket with Ocular Infection History.

Introduction: A novel technique of using a sandwich-like structure, namely, an oral mucosa graft (OMG)-conjunctiva in situ-dermis-fat graft (DFG) (OMG-C-DFG), to reconstruct a contracted and low-capacity anophthalmic socket for a patient with ocular infection history was evaluated.

Methods: This was retrospective case study of four patients (cases) who underwent anophthalmic socket reconstruction surgery in which the OMG-C-DFG technique was applied. The procedures were performed in the Department of Ophthalmology at the Ninth People's Hospital, Shanghai JiaoTong University School of Medicine (Shanghai, China).

Melatonin concentrations in serum of primary glaucoma patients.

Aim: To determine whether glaucoma patients exhibit an abnormal melatonin concentration in serum and the effects of psychiatric disorders caused by glaucoma in melatonin secretion.

Methods: A sample of 80 primary angle-closure glaucoma (PACG) patients, 120 primary open angle glaucoma (POAG) patients, and 120 normal controls were enrolled in this study. All the participants were asked to complete the following questionnaires: Pittsburgh sleep quality index (PSQI), self-rating anxiety scale (SAS), and self-rating depression scale (SDS).

Effect of Moisture Chamber Spectacles on Tear Functions in Dry Eye Disease.

Purpose: To evaluate the effect of moisture chamber spectacles (MCS) on tear functions in dry eye subjects.

Methods: In this short-term study, 30 subjects with dry eye were recruited and randomly divided into two groups. Fifteen subjects (MCS group) were instructed to wear the appropriately sized MCS for a total of 90 min.
