Cataracts, glaucoma, and age-related macular degeneration are known as major ocular problems which cause blindness among the elderly population worldwide. Oxidative stress plays an important role in both the initiation and progression of ocular problems and with respect to this; dietary antioxidants can serve as a therapeutic strategy for the improvement of ocular health. Zeaxanthin is known as one of the most important and common xanthophyll carotenoids, possessing multiple therapeutic effects such as strong antioxidant and pro-oxidant behaviour as well as anti-inflammatory effects. A growing body of literature shows that zeaxanthin mitigates ocular problems and suppresses oxidative stress in the retinal tissues. This paper aims to critically review the available literature regarding the beneficial effects of zeaxanthin on ocular problems with emphasis on its chemistry, bioavailability, and sources.

Handling venomous snakes poses a significant risk of envenomation. In the case of spitting cobras, additional precautions, like wearing face shields, are necessary to prevent ophthalmic envenomation. Although, the Monocled Cobra (Naja kaouthia) is not a true spitting cobra, however some spitting events has been reported from Northeastern India and Nepal but ocular envenomation is scarce.

Ptosis is defined as an abnormally low-lying upper eyelid margin on the primary gaze, generally resulting from a congenital or acquired abnormality of the nerves or muscles that control the eyelid. Ptosis can occur alone or concurrently as an ocular or systemic syndrome, and the prevalence of ptosis varies among different countries and populations. Isolated ptosis typically causes aesthetic problems in patients and can lead to functional ophthalmic problems in severe cases.

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.
