etiology of amblyopia• progressive suppression of visual input from eye receiving suboptimal image(blurry, deviated)
• in approximately half of the cases, amblyopia is secondary to strabismus (mainly ☆esotropia)
• other causes may include ★uncorrected refractive errors, anisometropia 不同視弱視 (asymmetric refractive errors, usually in the more ☆hyperopic eye), and deprivation due to structural ocular problems (ptosis, cataract, corneal opacity/scarring, retinoblastoma) ophthalmology卒試UWorld step2CK Oct 18, 2020, 8:22 AM HirotoShishido

treatment of hyperkalemia■ [K+] <6.5 and normal ECG
◆ treat underlying cause, stop K+ intake, increase the loss of K+ via urine and/or GI tract
■ [K+] between 6.5 and 7.0, no ECG changes: add insulin to above regimen
■ [K+] >7.0 and/or ECG changes: first priority is to protect the heart, add ★calcium gluconate (counterbalances the membrane depressive effect of hyperkalemia) to above electrolytes卒試UWorld step2CK Oct 14, 2020, 5:01 AM HirotoShishido
