Scleral collagen cross linkage in progressive myopia.

High myopia is often associated with local ectasia and scleral thinning. The progression of myopia depends upon scleral biochemical and biomechanical properties. Scleral thinning is associated with decreased collagen fiber diameter, defective collagen fibrillogenesis, and collagen cross-linking.

COVID-19 Vaccine Antibody Response in a Single-Center Urban Hemodialysis Unit.

Background: The longitudinal response to the COVID-19 vaccines among patients on hemodialysis with and without prior SARS-CoV-2 infection has not been well characterized.

Methods: To guide vaccination strategies in patients on hemodialysis, it is critical to characterize the longevity and efficacy of the vaccine; therefore, we conducted a prospective single-center monthly antibody surveillance study between March 2021 and March 2022 to investigate the dynamic humoral response to a series of COVID-19 mRNA vaccines in patients on hemodialysis with and without prior SARS-CoV-2 infection. Monthly quantitative antibody testing was performed using the Beckman Coulter Access SARS-CoV-2 IgG Antibody Test©, which detects IgG antibodies targeting the receptor binding domain (RBD) of the SARS-CoV-2 spike protein.

Topical vitamin C, vitamin E, and acetylcysteine as corneal wound healing agents: A comparative study.

Purpose: The purpose of this study was to evaluate wound healing abilities and efficacy of topical Vitamin C, Vitamin E, and acetylcysteine for their possible clinical use.

Methods: The study was conducted on 36 eyes of 18 single-breed rabbits, Oryctolagus cuniculus, of both sexes. A 7.

Pattern of ocular morbidity among students in a school for visually impaired children in North India.

Aims: The aim of this study was to identify the ocular morbidity pattern among children attending a blind school in North India and comparing the data with similar studies conducted across India and abroad.

Study Design: This was a cross-sectional observational study.

Materials And Methods: A cross-sectional study was performed during September 2017 where 94 students attending a blind school were interviewed, and a detailed ocular examination was performed by an ophthalmologist.

Incredibly late thromboses in first generation drug eluting stents: a case series.

Background: The drug-eluting stents have decreased the incidence of instent restenosis compared to bare metal stents. But, the incidence of late and very late stent thrombosis has increased with the drug-eluting stents.

Case Presentation: We are here, reporting three cases of incredibly late instent thrombosis, each one occurring after more than 50 months of drug-eluting stent placement.

Serum cortisol and testosterone levels in idiopathic central serous chorioretinopathy.

Context: The preferential occurrence of idiopathic central serous chorioretinopathy (ICSC) in males with a typical Type A personality and behavior and a relative absence in females is a possible indicator towards the role of serum cortisol and /or the male sex hormone testosterone.

Aims: To study levels of cortisol and testosterone in ICSC.

Settings And Design: Case-control study in a tertiary care teaching hospital.

Systemic absorption of triamcinolone acetonide after posterior sub-Tenon injection.

Purpose: To study systemic absorption of triamcinolone acetonide (TA) after posterior sub-Tenon injection.

Design: Prospective, interventional case series.

Methods: The study was conducted in a tertiary care teaching hospital on 35 eyes in which posterior sub-Tenon injection of 40 mg TA was administered after conventional extracapsular cataract extraction.

Capnography monitoring enhances safety of postoperative patient-controlled analgesia.

Background: Patient-controlled analgesia is associated with potentially fatal opioid-related respiratory depression. Opioids are a well-recognized cause of respiratory depression. However, in the postoperative patient, unrecognized pulmonary disease may lead to retention of carbon dioxide, which is further antagonized by opioids and may lead to life-threatening respiratory depression.
