Significance of Ocular surface
The ocular surface, as defined by both Ayurveda and Health Sciences, refers to the outermost layer of the eye, primarily encompassing the cornea and conjunctiva. It is crucial for maintaining eye health, tear film stability, and overall visual function. This area is susceptible to various conditions like dry eye syndrome, infections, and allergic reactions. Treatments, including traditional Ayurvedic remedies like Anjana and Tarpana, and modern approaches such as drug-loaded nanoparticles, aim to address issues affecting this critical area.

Hindu concept of 'Ocular surface'
In Hinduism, "Ocular surface" refers to the eye's outermost layer, crucial for tear film, oxygen supply, and defense against infection. It's relevant in understanding dry eye syndrome, Timira classification, and treatments like Shatavari Ghrita and Tarpana.

(1) The physiology of the ocular surface can be compromised quantitatively or qualitatively which leads to dry eye syndrome with various ocular discomfort symptoms.[1] (2) Ocular surface is where Anjana acts as a foreign body, and in response, the eyes produce reflex secretion.[2] (3) This is the area of the eye that is the primary focus of the study, as dry eye is a disease of this area, and the treatments are intended to address issues affecting this specific area.[3] (4) This is where Shatavari Ghrita, which is rich in lipid, forms a uniform layer on, which reduces excessive evaporation of tear and prevents Dry Eye.[4] (5) The continuous moisture and lubrication on the ocular surface, which includes the cornea and conjunctiva, provides oxygen to the corneal epithelium and prevents infection due to the presence of anti-bacterial substances.[5]

(1) The purpose of managing burns is to eliminate or limit the causative agent from penetrating the ocular structures, promoting healing through intervention.[7] (2) It is accompanied by increased osmolarity of the tear film and inflammation of the, as described in the definition of dry eye.[8] (3) This refers to the external area of the eye, where conditions such as seasonal and perennial allergic conjunctivitis manifest, typically due to contact with airborne allergens and the subsequent release of histamine.[9] (4) The surface of the eye is susceptible to damage and inflammation, and the definition of dry eye highlights its involvement in a multifactorial disease, which also includes the tears.[10] (5) OSSN includes a wide spectrum of dysplastic changes of the squamous epithelium of this part of the eye.[11]
