Clinical Outcomes of Femtosecond Laser-assisted Implantation of 325-Degree Versus 340-Degree Arc Length Intracorneal Ring Segments in Naive Keratoconic Eyes.

Purpose: To evaluate and compare clinical outcomes after femtosecond laser-assisted implantation of 325-degree versus 340-degree arc length intracorneal ring segments (ICRS) in eyes with keratoconus (KCN).

Methods: In this prospective non-randomized interventional case series, 23 eyes of 21 patients diagnosed with KCN, underwent femtosecond laser-assisted implantation of two types of ICRS, which included a 325-degree ICRS (Group 325) and a 340-degree ICRS (Group 340). The primary outcome measures were uncorrected distance visual acuity (UDVA), and the secondary outcome measures included corrected distance visual acuity (CDVA), sphere, cylinder, mean refractive spherical equivalent (MRSE), keratometry, vectorial change in corneal astigmatism, and the location of maximum keratometry relative to the corneal apex.

Introduction: Significant corneal flattening and haze are important complications that can occur after combined corneal collagen cross-linking (CXL) and photorefractive keratectomy (PRK) procedures (CXL Plus).

Case Presentation: We present a 24-year-old man who underwent combined standard CXL and PRK. The patient experienced satisfactory vision for approximately 4 years after the surgery.

Management of Large Conjunctival Cysts in a Patient with Stevens-Johnson Syndrome: A Case Report and Review of the Literature.

Stevens-Johnson syndrome (SJS) is a life-threatening mucocutaneous disease with various etiologies including drugs, infections, and malignancies. Ocular manifestations of SJS vary from the membrane, symblepharon formation, and epithelial defect in the acute phase to trichiasis, eyelid margin keratinization, and lacrimal duct obstruction in the chronic phase. A 13-year-old boy with a history of drug-induced SJS presented to our clinic complaining of a mass in the nasal side and inferior fornix of the right eye from 1 year ago.

Safety and Efficacy of Topical Vitamin D in the Management of Dry Eye Disease Associated With Meibomian Gland Dysfunction: A Placebo-Controlled Double-Blind Randomized Controlled Trial.

Purpose: The aim of this study was to investigate the safety and efficacy of topical vitamin D in the management of dry eye disease associated with meibomian gland dysfunction (MGD).

Methods: In this randomized controlled trial, patients with symptomatic MGD were divided into 2 groups to receive topical vitamin D drops or placebo in their randomized eyes. The exclusion criteria consisted of patients with vitamin D deficiency, previous ocular surgery, and patients with ocular diseases affecting the tear film.

Mini-Conjunctival Limbal Autograft (Mini-CLAU) Using Platelet-Rich Plasma Eye Drops (E-PRP): A Case Series.

Purpose: The purpose of this study was to introduce a new method of limbal stem cell transplantation using autologous platelet-rich plasma (E-PRP) eye drops for unilateral total limbal stem cell deficiency.

Methods: Patients with total unilateral limbal stem cell deficiency due to chemical burn underwent mini-conjunctival limbal autograft using autologous E-PRP drops. One small limbal block, measuring 2 × 2 mm, was harvested from the patients' contralateral healthy eye and transplanted to the diseased eye.

Introducing a mobile learning model in medical education during COVID-19; a critical review.

Introduction: Mobile learning is one of the innovative teaching techniques that help medical students gain knowledge and skills. One of the factors that expanded the use of this strategy was the COVID-19 pandemic. However, the educational pedagogy of such technology has been neglected.

Is retinal nerve fibre layer thickness correlated with visual function in individuals having optic neuritis?

Clinical Relevance: The existence of a correlation between the results of paraclinical retinal imaging and clinical tests such as contrast sensitivity can reduce time and cost in diagnosing optic neuritis (ON).

Background: To demonstrate whether changes of peripapillary retinal nerve fibre layer (RNFL) thickness are correlated with the results of visual acuity, contrast sensitivity and colour vision in eyes with acute ON.

Methods: Thirty patients with acute ON, 23 females and seven males, who had no previous history of ON in neither eye, were examined.

Corona virus disease 2019-associated Stevens-Johnson syndrome: a case report.

Background: To report Stevens-Johnson syndrome (SJS) in a patient with acute pneumonia secondary to SARS-CoV-2 infection.

Case Presentation: A 45-years-old woman with a diagnosis of acute pneumonia secondary to SARS-CoV-2 infection who had received azithromycin and naproxen. Three days after starting the medication, she appeared ill and developed ocular discomfort, photophobia, dysuria, and macular rashes on the trunk and the extremities.

Systemic supplemental oxygen therapy during accelerated corneal crosslinking for progressive keratoconus: randomized clinical trial.

Purpose: To investigate the potential additive effect of systemic supplemental oxygen administered during accelerated corneal crosslinking (CXL) for progressive keratoconus (KC).

Setting: Academic center.

Design: Randomized clinical trial.

Correlation Between Low-Dose Chest Computed Tomography and RT-PCR Results for the Diagnosis of COVID-19: A Report of 27,824 Cases in Tehran, Iran.

Rationale And Objectives: Real-time polymerase chain reaction (RT-PCR) remains the gold standard for confirmation of Coronavirus Disease 2019 (COVID-19) despite having many disadvantages. Here, we investigated the diagnostic performance of chest computed tomography (CT) as an alternative to RT-PCR in patients with clinical suspicion of COVID-19 infection.

Methods: In this descriptive cross-sectional study, 27,824 patients with clinical suspicion of COVID-19 infection who underwent unenhanced low-dose chest CT from 20 February, 2020 to 21 May, 2020 were evaluated.

Development and validation of the shared governance feasibility instrument in nursing schools in Iran.

Abstract: To develop and validate a shared governance feasibility instrument in schools of nursing in Iran with respect to the nature of the profession and the sociocultural context of the Iranian community.

Background: Nursing schools are liable to the application of shared governance due to the presence of various expert educational groups within the school that necessitates reciprocal cooperation. Since the concept of shared governance is culture-based and given that no full-fledged study has been conducted on shared governance in Iran, the development of a suitable shared governance feasibility instrument is rendered as mandatory.

Factors predisposing to shared governance: a qualitative study.

Background: The method of implementing shared governance varies among organizations. Identifying the predisposing factors can facilitate and precipitate its successful implementation and aid educational institutions in achieving their goals. This study determined the antecedents of shared governance in nursing schools.

Characteristics of Shared Governance in Iranian Nursing Schools: Several Souls in One Body.

Background: Shared governance is a decentralized structural model that gives individuals the right to make decisions and a position analogous to managers. The shared governance is different based on context in every organization. This study identified the characteristics of shared governance in Iranian nursing schools.
