Background: Pediatric cataract is an important cause of avoidable childhood blindness in India. Although there are studies on clinical features and visual acuity outcomes of pediatric cataract surgery, there are no studies that look into aspects of color vision, stereopsis, and cognitive functions in children with cataracts. Studying these parameters pre- and postsurgery will help us assess the overall components of visual function that are critical for the child's development.

- Exotropic-Duane Syndrome (XT-DRS) is a congenital eye condition resulting in symptoms like exotropia, anomalous head posture, and difficulties with eye movement due to abnormal nerve function.
- The study focuses on two patients who underwent a specialized surgical procedure combining lateral rectus muscle disinsertion and a modification of the Nishida procedure to improve their eye alignment and movement.
- Post-surgery, both patients showed significant improvements, including reduced exotropia and head posture issues, as well as enhanced convergence ability.
Purpose: The aim of this study was to compare the ultrasonographic optic nerve sheath diameter (ONSD) in different grades of papilledema and in controls and to evaluate ONSD in atrophic papilledema/optic atrophy when raised ICP was suspected.
Methods: Prospective cross-sectional case-control study. Following an ocular examination, papilledema was graded clinically using modified Frisén's grading.
A short, stereoselective, and a common approach for the synthesis of 4,5-disubstituted delta-lactones simplactone B and its analogue using Evans protocol is described.
