Administration methods and approaches for myopia

Abstract: conjunctival sac flushing can be used to flush the conjunctival sac with eye flushing solution when removing irritants, foreign bodies or secretions in the conjunctival sac. The commonly used eye flushing solution is sterile 0.9% sodium chloride solution. In case of emergency, clean water can also be used as eye rinse. The most commonly used method of

ophthalmology is topical administration of eye drops, such as eye drops (including solutions, suspensions, emulsions, etc.), eye gel or eye ointment, etc., dripped into or coated into conjunctival sac. If eye treatment requires high drug concentration, local eye injection can be used, such as subconjunctival injection, intraocular injection, etc.

the method of administration of eye drops in conjunctival sac is usually to ask the patient to lie on his head later and look up. The dropper gently pulls down the lower eyelid with his fingers, and then slowly drops the drug into the lower fornix, generally 1 drop. Gently lift the upper eyelid to fully diffuse the drug solution in the conjunctival sac. Ask the patient to gently close the eyelids for 2 ~ 3 minutes. Wipe off the liquid medicine flowing out of the conjunctival sac with a dry cotton ball. Ophthalmic gel and eye ointment are similar to eye drops. Gel or eye ointment is applied to the lower fornix of conjunctival sac. Gently closing the eyes and massaging the eyes after medication are helpful to the diffusion of drugs.

when two different eye drops are used at the same time, if the second one is used immediately after using one, the drug will be diluted or the drug will overflow the conjunctival sac. Therefore, when two eye drops need to be used at the same time, the second eye drops should be used after using one for at least 5 minutes. The drugs dropped into the conjunctival sac by

and

can be absorbed through the conjunctival vessels, or the excess drugs in the conjunctival sac can flow into the nasal cavity from the nasolacrimal duct and enter the systemic circulation through the nasal mucosa, which can cause systemic effects, and its degree is greatly related to the dosage form administered to the eyes. The drugs injected into the nasal cavity through nasolacrimal duct are mostly related to eye drops, but rarely with eye gel and eye ointment. When using eye drops, gently pressing the lacrimal sac area of the inner canthus with your fingers can significantly reduce the amount of drugs flowing into the nasal cavity through the nasolacrimal duct, so as to reduce the systemic effects caused by drugs.

subconjunctival injection in order to effectively control the disease, or when the curative effect is not significant after intrathecal administration, anti infective drugs, mydriasis agents or glucocorticoids can be administered by subconjunctival injection. Drugs spread to anterior chamber, posterior chamber and vitreous body through cornea and sclera. The volume of a single dose injected under the conjunctiva is limited, usually no more than 1 ml.

intraocular injection in order to effectively control the disease and improve the curative effect, intraocular injection can be used when necessary, including anterior chamber injection and intravitreal injection. Since the dose volume of drugs has a certain limit, the volume of a single dose usually does not exceed 0.3ml. Because intraocular injection may have some serious complications, it should be used with caution.

systemic administration of some drugs, such as antibiotics and glucocorticoids, can be used to treat some ocular diseases. Some intraocular pressure lowering drugs also need systemic administration, such as oral acetazolamide, glycerin saline, intravenous drip of hypertonic agent mannitol, etc., to achieve the goal of rapidly reducing intraocular pressure.
