From the Guidelines
Restarting timolol eyedrops for a cauda equina syndrome patient on steroids should be done with caution and under the guidance of a healthcare provider, as the combination of medications requires careful consideration of potential interactions and side effects. Timolol is a beta-blocker medication typically used to reduce intraocular pressure in glaucoma patients, while cauda equina syndrome is a serious neurological condition affecting the bundle of nerve roots at the lower end of the spinal cord. These conditions are unrelated, and the combination of medications requires careful consideration. Steroids used for cauda equina syndrome can potentially increase intraocular pressure in some patients, which might seem to justify timolol use. However, beta-blockers like timolol can interact with other medications and may be contraindicated in patients with certain respiratory conditions or cardiovascular issues, as noted in a study published in Hypertension in 2022 1.
The potential risks and benefits of restarting timolol eyedrops in this patient population must be carefully weighed, taking into account the patient's individual medical history and current condition. According to a study published in Ophthalmology in 2021, topical beta adrenergic antagonists, such as timolol, are commonly prescribed to treat glaucoma and have demonstrated good efficacy and tolerability 1. However, the study also notes that nighttime dosing of beta-blockers is associated with limited efficacy and may contribute to visual field progression via nocturnal reduction of systemic blood pressure.
Another study published in Ophthalmology in 2021 highlights the importance of patient education and informed participation in treatment decisions to improve adherence and overall effectiveness of management 1. The study suggests that patients should be educated about the proper use of eye drops, including techniques to reduce systemic absorption, and that healthcare providers should assess patients for local ocular and systemic side effects and toxicity, including interactions with other medications.
In light of these findings, it is essential for the patient to discuss the potential risks and benefits of restarting timolol eyedrops with their neurologist and ophthalmologist to ensure proper coordination of care and to evaluate the risk-benefit profile based on their individual medical history and current condition. The healthcare provider should carefully consider the patient's medical history, current condition, and potential interactions between medications before making a decision about restarting timolol eyedrops.

From the Research
Cauda Equina Patient on Steroids
- The use of steroids in patients with cauda equina can lead to increased intraocular pressure (IOP) due to steroid-induced ocular hypertension and glaucoma 2, 3.
- Timolol eyedrops are commonly used to lower IOP in patients with glaucoma or ocular hypertension 4, 5, 6.
Restarting Timolol Eyedrops
- There is no direct evidence to suggest that restarting timolol eyedrops is harmful for cauda equina patients on steroids.
- However, it is essential to monitor IOP closely when restarting timolol eyedrops, as the combination of steroids and timolol may affect IOP levels 2, 3.
- Fixed-combination drugs containing timolol, such as latanoprost/timolol, travoprost/timolol, and bimatoprost/timolol, have been shown to effectively lower IOP in patients with primary open-angle glaucoma and ocular hypertension 4, 5, 6.
Considerations
- The decision to restart timolol eyedrops should be made on a case-by-case basis, taking into account the individual patient's medical history, current IOP levels, and steroid use 2, 3.
- Regular monitoring of IOP and adjustment of treatment as needed is crucial to prevent complications associated with steroid-induced ocular hypertension and glaucoma 2, 3.
