Widespread screening is crucial for the early diagnosis and treatment of glaucoma, the leading cause of visual impairment and blindness. The development of portable technologies, such as smartphone-based ophthalmoscopes, able to image the optical nerve head, represents a resource for large-scale glaucoma screening. Indeed, they consist of an optical device attached to a common smartphone, making the overall device cheap and easy to use.

The choroid, a critical vascular layer beneath the retina, is essential for maintaining retinal function and monitoring chorioretinal disorders. Existing imaging methods, such as indocyanine green angiography (ICGA) and optical coherence tomography (OCT), face significant limitations, including contrast agent requirements, restricted field of view (FOV), and high costs, limiting accessibility. To address these challenges, we developed a nonmydriatic, contrast agent-free fundus camera utilizing transcranial near-infrared (NIR) illumination.

Purpose: To assess the relationship between angle kappa (apparent chord mu) and ocular parameters in cataract patients.
Methods: In this cross-sectional study, the data on apparent chord mu, age, axial length, anterior chamber depth, anterior and posterior mean keratometry, mean total keratometry, white-to-white, central corneal thickness and lens thickness were collected for consecutive cataract patients. Correlation (Pearson) between chord mu and the other ocular parameters was calculated.

We present a case of a young woman who presented with blurring of vision in her right eye, worsening on near work. Detailed ophthalmic and neurological evaluation was done, which revealed light near dissociation, vermiform iris movements, constriction to diluted pilocarpine with absent deep tendon reflexes. Laboratory investigation indicated mild iron deficiency anemia and reduced vitamin D3 level.

For the past 50 years, significant progress has been made in understanding Seasonal Hyperacute Panuveitis (SHAPU), a mysterious blinding disease first reported in Nepal in 1975. Predominantly affecting Nepalese children, SHAPU occurs cyclically every odd year from September to December. While initially misclassified as endophthalmitis, SHAPU is set apart by its lack of trauma or surgery, failure to grow organisms in most intraocular fluid cultures, and its hallmark presentation of a "white pupil in red eye" with an association with moth exposure.
