The practice of administering glaucoma medication in the evening is a common recommendation by ophthalmologists. This timing is often suggested to coincide with the body’s natural circadian rhythms and to potentially maximize the effectiveness of the medication. For instance, intraocular pressure (IOP), the fluid pressure inside the eye, tends to be higher during sleep or in the early morning hours for many individuals. Medication delivered at night can, therefore, work to control this peak in pressure.
Lowering IOP is the primary treatment goal in managing glaucoma, a condition that can damage the optic nerve and lead to vision loss. Adhering to a prescribed medication schedule is crucial for preventing disease progression. The evening application allows the medication to be actively working throughout the night, potentially preventing a damaging IOP spike. Historically, this timing has been found beneficial in clinical studies examining intraocular pressure fluctuations and medication efficacy.
