There are two major categories of eye drops most commonly used clinically for scleral disease: one is glucocorticoid eye drops, such as compound tobramycin eye drops and flomylone eye drops; the other is non-steroidal anti-inflammatory drugs, such as diclofenac sodium eye drops and pralofen eye drops. The sclera is the outermost layer of the eye wall, tough and milky white, with relatively few blood vessels on the sclera. The clinical characteristics of scleral disease are a long course, difficult to heal, and recurrent attacks, which are accompanied by eye pain, photophobia, and lacrimation, etc. According to the involvement of the inflammation, scleral inflammation can be divided into superficial scleral inflammation and scleritis.
