Management of Recurrent Keratitis as a Complication of Black Scorpion Sting: A Case Report.

Scorpions are a group of arthropods known to be highly toxic to humans. We report the case of a previously healthy 61-year-old male who sustained a sting from an Androctonus crassicauda scorpion to his right eye. The patient was admitted to the intensive care unit (ICU) in a comatose state immediately after the sting.

Evaluating accuracy and reproducibility of ChatGPT responses to patient-based questions in Ophthalmology: An observational study.

Chat Generative Pre-Trained Transformer (ChatGPT) is an online large language model that appears to be a popular source of health information, as it can provide patients with answers in the form of human-like text, although the accuracy and safety of its responses are not evident. This study aims to evaluate the accuracy and reproducibility of ChatGPT responses to patients-based questions in ophthalmology. We collected 150 questions from the "Ask an ophthalmologist" page of the American Academy of Ophthalmology, which were reviewed and refined by two ophthalmologists for their eligibility.

Successful Management of Bilateral Uncontrolled Advanced Primary Open Angle Glaucoma in a Pregnant Woman during the Restrictive COVID-19 Lockdown.

COVID-19 is a viral illness that can cause severe respiratory symptoms. COVID-19 has caused a worldwide pandemic that necessitated many countries to perform a national lockdown. In Jordan, a lockdown was imposed by the government.

Outcomes of Iris-Claw IOL Implantation in Patients with Marfan's Syndrome in Jordan.

Objective: The management of ocular complications of Marfan's syndrome, especially ectopia lentis, is challenging. In this study, we present the effectiveness and the safety of iris-claw intraocular lens (IOL) implantation along with lensectomy for those patients. Also, we compare the practice of implanting these IOLs either in the anterior chamber of retropupillary.

Descemet Stripping Automated Endothelial Keratoplasty: The influence of preoperative endothelial cell density and triple procedures on grafts at 5 years postoperative.

The purpose is to determine if the preoperative central endothelial cell density (ECD) in triple (phacoemulsification plus intraocular lens implantation plus DSAEK) and non-triple Descemet Stripping Automated Endothelial Keratoplasty (DSAEK) procedures have a relationship with the 5-year postoperative ECD or percent Endothelial Cell Loss (ECL).Out of 986 consecutive DSAEK surgeries for Fuchs dystrophy, 241 eyes had 5-year ECD measurements available. Endothelial cell densities were then evaluated against preoperative ECDs to obtain measures of ECL.

COVID-19 Lockdown and Eye Injury: A Case Series from Jordan.

Novel coronavirus or COVID-19 is a viral illness that can cause severe respiratory symptoms. It spreads between people through direct, indirect (through contaminated objects or surfaces), or close contact with infected people via mouth and nose secretions. COVID-19 has caused a worldwide pandemic that necessitated many countries to perform a national lockdown.

Clinical Experience in the Administration of Intravitreal Injection Therapy at a Tertiary University Hospital in Jordan During the COVID-19 Lockdown.

Purpose: To describe the clinical experience with the delivery of intravitreal injection therapy to patients with various indications at a tertiary university hospital during the COVID-19 lockdown in Jordan.

Methods: This is a retrospective observational study of patients who received intravitreal injections between April 12th and May 9th, 2020, a period during the national COVID-19 lockdown (March 16th to June 6th, 2020). Special medical and logistic arrangements, priority and visual risk assessment and strict infection control precautions were implemented.

The Last 200 Surgeon-Loaded Descemet Membrane Endothelial Keratoplasty Tissue Versus the First 200 Preloaded Descemet Membrane Endothelial Keratoplasty Tissue.

Purpose: The purpose of this study was to compare the clinical outcomes from using eye bank-prepared, endothelium-out preloaded Descemet membrane endothelial keratoplasty (DMEK) tissue with those obtained with endothelium-out surgeon-loaded DMEK tissue using the same surgical technique at 1 site.

Methods: This study retrospectively reviewed 400 consecutive cases of DMEK from March 2016 to April 2018. The last 200 cases using surgeon-loaded tissue were compared with the first 200 cases using preloaded tissue.

Genetic Analysis Of Gene Of Primary Glaucoma In Jordanian Arab Population.

Background: Glaucoma is a neurodegenerative disease that leads to progressive loss of retinal ganglion cells, causing irreversible visual field defects. At the present time, glaucoma is clinically defined but the exact etiology is unknown. The aim of this study is to genotype rs2472493 and rs2487032 SNIPs within gene in 52 Jordanian Arab patients with primary glaucoma and 96 control subjects, and also to investigate the genetic association of these SNPs with primary glaucoma.

Endothelial keratoplasty: The relationship between recipient anterior chamber depth and endothelial cell loss.

Purpose: To determine the relationship between anterior chamber depth (ACD) and percent endothelial cell loss (ECL) after Descemet Stripping Automated Endothelial Keratoplasty (DSAEK).

Method: In 78 eyes receiving triple procedure (DSAEK combined with cataract extraction and posterior chamber intraocular lens (PCIOL) implantation), ACD was measured preoperatively with an intraocular lens (IOL) Master and ECL was calculated with specular microscopy at 6 months, 1, 2, 3, and 4 years postoperatively. ACD and ECL from all 78 eyes were compared using correlation analysis and students t test.

Vision-related Quality of Life in Glaucoma Suspect or Early Glaucoma Patients.

Purpose: To determine the association of vision-related quality of life (QoL) to demographic factors and visual function in glaucoma suspect or early glaucoma patients.

Materials And Methods: We administered the 25-item National Eye Institute Visual Function Questionnaire (VFQ-25) on the same day as a comprehensive ocular examination to participants either with glaucoma or at high risk for developing glaucoma. Regression models were used to determine the association between VFQ-25 composite and subscale scores, visual field status, logMAR equivalent visual acuity (VA), age, and sex.

Immediate endothelial cell loss after penetrating keratoplasty.

Purpose: To report the pattern and the extent of corneal endothelial cell loss immediately after a penetrating keratoplasty (PK) is performed.

Methods: Ten donor corneal-scleral tissues with healthy endothelium were used to perform 10 PK surgeries on cadaver eyes. An 8.

Endothelial keratoplasty: prospective, randomized, masked clinical trial comparing an injector with forceps for tissue insertion.

Purpose: To compare the complications and outcomes of Descemet stripping automated endothelial keratoplasty (DSAEK) when the tissue is either folded and inserted with a forceps or inserted using a platform injector device without folding.

Methods: DSAEK was performed in 100 eyes of 79 patients undergoing DSAEK surgery for Fuchs corneal dystrophy.

In vitro evaluation of endothelial cell loss using the Neusidl Corneal Inserter.

Purpose: To determine the immediate endothelial cell loss (ECL) resulting from insertion of a precut donor button using the Neusidl Corneal Inserter (NCI) and compare it with the previously published ECL resulting from insertion of a folded donor button using non-coapting forceps.

Methods: Ten corneas were precut for Descemet stripping automated endothelial keratoplasty and trephinated to a diameter of 8.0 mm (n = 5) or 8.
