To resolve halation faster, use a combination of rest, cold compresses, and anti-inflammatory medications, as well as consider the use of brinzolamide as an adjunctive therapy to reduce intraocular pressure (IOP) and alleviate symptoms. Rest your eyes by taking breaks from screens and bright lights. Apply cold compresses to the affected eyes for 10-15 minutes several times daily to reduce inflammation and constrict blood vessels. Over-the-counter NSAIDs like ibuprofen (400-600mg every 6-8 hours) can help reduce inflammation. Artificial tears or lubricating eye drops used 4-6 times daily can soothe irritation. If you wear contact lenses, remove them until symptoms resolve. Stay hydrated and avoid smoke, dust, and other eye irritants. Halation (seeing halos around lights) often results from corneal edema or inflammation, and these measures help reduce the swelling and irritation causing the visual disturbance. According to a systematic review and meta-analysis 1, brinzolamide as an add-on to prostaglandin analogues or β-blocker significantly decreased IOP of patients with refractory glaucoma or ocular hypertension, and the adverse events were tolerable.
Some key points to consider:
- Brinzolamide is a highly specific carbonic anhydrase inhibitor that lowers IOP by reducing the rate of aqueous humour formation 2, 3.
- The IOP-lowering efficacy of brinzolamide is maintained for up to 12 months, and is no less effective than dorzolamide 2%/timolol 0.5% solution 4.
- Brinzolamide is generally well tolerated and is associated with significantly lower ocular discomfort scores than dorzolamide/timolol 4.
- The most common ocular adverse events associated with brinzolamide are blurred vision, ocular discomfort, and eye pain 3, 1.
If symptoms persist beyond 48-72 hours, worsen, or are accompanied by pain or vision changes, consult an eye care professional immediately as it could indicate a more serious condition requiring medical intervention.
