The authors present a case of an orbital apex venous malformation that presented with an intermittent oculomotor nerve palsy over a 15-year period. Radiologically, the lesion presented as a well-circumscribed orbital mass with T2 hyperintensity and enhancement that could only be demonstrated on 2-hour delayed phase imaging. The venous malformation was initially steroid-responsive but eventually became refractory to medical treatment alone.

Inhibitory killer cell immunoglobulin-like receptors (iKIRs) are a family of inhibitory receptors that are expressed by natural killer (NK) cells and late-stage differentiated T cells. There is accumulating evidence that iKIRs regulate T cell-mediated immunity. Recently, we reported that T cell-mediated control was enhanced by iKIRs in chronic viral infections.

Diabetic macular edema (DME) is a vision-threatening complication of diabetic retinopathy and causes significant morbidity in patients. Anti-vascular endothelial growth factor (VEGF) agents are the mainstay of treatment for DME, with steroid implants being used for the treatment of anti-VEGF resistant eyes. Over the years, several classification systems have been devised to describe the patterns of DME using optical coherence tomography (OCT).

Introduction: Annual screening for hydroxychloroquine (HCQ) retinopathy is recommended, and electroretinography (ERG) is considered a gold-standard test, but there are screening shortfalls and standard ERG is burdensome and has limited availability. Newer, portable ERG devices using skin-based electrodes may increase screening capacity but need validation. This study aims to determine initial device accuracies and feasibility of further research.

Introduction: Trachoma is caused by the bacterium (). The WHO recommends the SAFE strategy for trachoma elimination: Surgery for trichiasis, Antibiotics, Facial cleanliness and Environmental improvement. Multiple rounds of SAFE implementation have proven insufficient to eliminate trachoma in Ethiopia, where over 50% of the global trachoma burden remains.

Background:  Diabetes mellitus (DM) is a global disease that is strongly associated with both microvascular and macrovascular complications. A significant proportion of individuals with diabetes develop diabetic retinopathy (DR), a microvascular complication that can lead to blindness, particularly in working-age adults. Diabetes adversely affects the entire neurosensory retina, with accelerated neuronal apoptosis and activation or altered metabolism of neuroretinal supporting cells.

Diabetic vitrectomy is a highly intricate surgical procedure performed during the advanced stages of diabetic retinopathy (DR). It is used to treat conditions such as tractional or combined retinal detachment, vitreous hemorrhage, and subhyaloid hemorrhage, which are all severe manifestations of proliferative DR. The results of the surgery are uncertain and variable.

Diabetes mellitus (DM) is a chronic metabolic non-communicable disease with the ability to cause serious microvascular and macrovascular complications throughout the body, including in the eye. Diabetic retinopathy (DR), present in one-third of patients with diabetes, is a vision-threatening complication caused by uncontrolled diabetes, which greatly affects the retinal blood vessels and the light-sensitive inner retina, eventually leading to blindness. Several epidemiological studies elucidate that DR can vary by age of onset, duration, types of diabetes, and ethnicity.

We present 3 cases of bilateral anterior lens capsule rupture, all leading to a subsequent diagnosis of Alport syndrome. Clinicians should be alert to the ocular and systemic features of Alport syndrome, especially when presented with a spontaneous rupture of the anterior lens capsule in young males. Ophthalmologists are often the first contact for patients with Alport syndrome, and a sound knowledge of the associated features will enable timely referral to other members of a multidisciplinary team required to treat such patients.

Beijing Institute of Ophthalmology, Beijing Tongren Eye Center, Beijing Tongren Hospital, Capital Medical University, No. 1, Dongjiaomin Lane, Dongcheng District, Beijing, 100730, China.

Background: Age-related macular degeneration (AMD) is the leading cause of visual impairment in the elderly population. Accumulating evidence has revealed the possible association between metabolites and AMD. This study aimed to assess the effect of plasma metabolites on AMD and its two subtypes using a bidirectional two-sample Mendelian randomization approach.

Corneal alkali burns persist as a significant challenge in our field, often leading to a prolonged treatment course with various sight-threatening problems. This work, of utmost importance, aimed to apply the photo-tissue bonding technique (PTB) to weld the amniotic membrane (AM) to the corneal surface versus an amniotic membrane graft (AMG) and explore its safety in saving corneal protein against alkali burn.Methods Twenty-seven rabbits with an induced corneal ulcer using 1 mol/L NaOH solution.

Purpose: Mutations affecting the CRB1 gene can result in a range of retinal phenotypes, including early onset severe retinal dystrophy/Leber congenital amaurosis (EOSRD/LCA), retinitis pigmentosa, cone-rod dystrophy (CORD), and macular dystrophy (MD). As research into treatment strategies advances towards clinical translation, there is a need to establish reliable outcome metrics. This study explores the contrast sensitivity function (CSF) across different spatial frequencies in individuals with CRB1-retinopathies using the child-friendly PopCSF test, an iPad-based "gamified" assessment.

Background: Consanguineous marriage is a major contributing factor for many genetic diseases and a burden to the healthcare system and national economy due to costly long-term care. Earlier studies highlighted the significantly limited awareness of the higher prevalence of genetic disease due to consanguinity even among the educated Arabs. In Saudi Arabia, more than 50% of marriages are between first cousins.

The need for better and simpler alternative crosslinking strategies to treat keratoconus (KC) is becoming essential as there is only a single approved way to treat it. Recently, conventional UV-A Riboflavin crosslinking is proven to have some disadvantages such as causing damage to the corneal endothelium and inducing keratocyte apoptosis. A chemical cross-linker (CXL) using carbodiimide chemistry and an octanedioic acid spacer is found effective in stiffening the cornea and has the potential to be developed as an alternative therapy to halt KC progression.
