Can topiramate cause myopia?
By Caleb Butler
Can topiramate cause myopia?
The acute myopia associated with using topiramate has been reported at between 2 and 8.75 diopters and causing sudden bilateral blurring of vision (12).
How does Topamax affect the eyes?
Topamax and eye problems Topamax can cause severe eye conditions that may result in blindness. Acute myopia, which causes nearsightedness, can cause headaches or blurred vision because of increased pressure in the eye.
What is a myopic shift?
The progression of cataracts may frequently increase the dioptric power of the lens resulting in a mild-to-moderate degree of myopia or myopic shift. Consequently, presbyopic patients report an increase in their near vision and less need for reading glasses as they experience the so-called second sight.
How does topiramate cause angle closure?
Topiramate-induced angle closure is a rare but serious adverse reaction in which angle closure occurs due to development of ciliochoroidal effusions. This results in anterior rotation of the ciliary body and forward displacement of the lens-iris diaphragm [4].
What medications are sensitive to sunlight?
What medications make you sensitive to sunlight?
- Antibiotics (ciprofloxacin, doxycycline, levofloxacin, tetracycline, trimethoprim)
- Antifungals (flucytosine, griseofulvin, voriconazole)
- Antihistamines (cetirizine, diphenhydramine, loratadine, promethazine, cyproheptadine)
What is near sightedness called?
In nearsightedness (myopia), the point of focus is in front of the retina, making distant objects appear blurry. Nearsightedness (myopia) is a common vision condition in which you can see objects near to you clearly, but objects farther away are blurry.
Does Topamax have withdrawal symptoms?
Common Topamax withdrawal symptoms include anger, anxiety, appetite changes, trouble concentrating, confusion, dehydration, depersonalization, depression, dizziness, fatigue, headaches, migraines, insomnia, irritability, mood swings, muscle pain, nausea, panic attacks, seizures, shaking, sweating, thought changes.
Does Topamax help with anxiety?
The study found that the participants taking Topamax in addition to their prescribed depression medication significantly improved depressed mood, suicidality, insomnia, agitation, and anxiety symptoms compared to those taking a placebo.
Why does myopic shift occur?
As previously reported,1–5 nuclear cataract can cause significant myopic refractive error shifts. This is probably caused by symmetrical refractive index changes within the nucleus of the lens, causing negative spherical aberration and a myopic shift.
What causes a myopic shift?
Uveitic conditions that can induce a myopic shift include sclero-choroidal inflammation, lens induced myopia due to steroid cataracts, juvenile idiopathic arthritis (JIA) induced myopia, and transient drug induced myopia due to sulfonamides and acetazolamide used for treatment of ocular toxoplasmosis and inflammatory …
What kind of eye problems can topiramate cause?
Ocular adverse effects reported as attributable to Topiramate are: acute angle closure glaucoma, ocular pain, headache, hyperaemia, mydriasis, uveitis, visual field defects, acute onset myopia, suprachoroidal effusions, blepharospasm, oculogyric crisis, scleritis, and retinal haemorrhage [5].
Can topiramate cause eye pressure?
Results: A 27-year-old female patient developed decreased vision in both eyes due to acute myopia 2 weeks of after initiating therapy with topiramate. Emergency department evaluation revealed visual acuities of 20/400 right eye and 20/200 left eye. Intraocular pressures were 33 mm Hg right eye and 26 mm Hg left eye.
