Article Synopsis
- Lip, oral, and pharyngeal cancers pose significant global health challenges, making it essential to analyze their burden for effective health policies.
- The study utilized data from the 2019 Global Burden of Diseases, Injuries, and Risk Factors Study to assess cancer incidence, mortality, and life years lost across 204 countries, linking these to socio-demographic factors.
- Findings revealed approximately 370,000 cases and 199,000 deaths for lip and oral cavity cancer, and 167,000 cases and 114,000 deaths for other pharyngeal cancers in 2019, with smoking being the leading risk factor for these cancers, especially in low and middle SDI regions.
Ocular toxocariasis in humans is caused by infection with larvae of species, which are common ascarid roundworms of mammals, kept in close proximity to human. Four cases with a history of contact with dogs and cats and blurred vision and visual impairment over periods of variable duration were examined. We screened patients diagnosed with ocular larva migrans syndrome between March and June 2021 at the Ophthalmology clinics affiliated with Alborz University of Medical Sciences, Karaj, Iran.

- - The case study reports a 43-year-old man who developed bilateral central retinal vein occlusion (CRVO) along with Stevens-Johnson syndrome (SJS) after being infected with COVID-19.
- - He experienced severe symptoms, including flu-like symptoms, a facial rash, and respiratory distress, leading to hospitalization where he tested positive for the virus.
- - Despite treatment with medications like dexamethasone and remdesivir, his condition worsened, and he unfortunately passed away six days after being admitted.
Background: Assessment is a necessary part of training postgraduate medical residents. The implementation of methods located at the "shows how" level of Miller's pyramid is believed to be more effective than previous conventional tools. In this study, we quantitatively compared electronic and conventional methods in assessing ophthalmology residents.

This virus expanded worldwide, causing global concern. Although clinical, laboratory, and imaging features of COVID-19 are characterized in some observational studies, we undertook a systematic review and meta-analysis to assess the frequency of these features.

Methods: In this study, five cases with posttraumatic orbital subperiosteal hematoma were studied and reviewed along with similar cases in a systematic literature review.
Results: The mean age of our patients was 9.
Corneal keratopigmentation (KTP) has a long history of use in management of patients suffering from disfiguring corneal opacities. Due to progresses and modifications in KTP surgical techniques and its low rate of complications, it is taken into consideration to be used in selected groups of patients for therapeutic or functional indications. In this paper we present an overview on clinical applications of KTP in both cosmetic and functional aspects and also, we discuss the outcomes of KTP and its characteristics in experimental and histopathological studies.

Design: Randomized, parallel-controlled clinical trial.
Methods: Setting: Single tertiary referral hospital.
Purpose: To compare the outcomes of the conventional and accelerated corneal collagen cross-linking (CXL) in patients with bilateral progressive keratoconus (KC).
Methods: Fifteen consecutive patients with bilateral progressive KC were enrolled. In each patient, the fellow eyes were randomly assigned to the conventional CXL (3 mW/cm for 30 min) or accelerated CXL (ACXL) (9 mW/cm for 10 min) groups.
Purpose: To determine the effect of retained donor Descemet membrane (DMs) on visual outcomes, contrast sensitivity (CS), higher-order aberrations (HOAs), and central graft thickness after deep anterior lamellar keratoplasty (DALK) using the big-bubble technique.
Methods: In this retrospective comparative study, keratoconic eyes undergoing a DALK using the big-bubble technique were enrolled. A bared DM was achieved in all cases.
