  • Acute Hydrops: Rethinking Treatment - American Academy of

    A Shift in The ParadigmResearch OverviewReal-World ConcernsLooking ForwardConventional treatment of hydrops includes topical antibiotics, cycloplegics, and hypertonic saline as well as patching and bandage soft contact lens. When treated conservatively, the edema tends to resolve over two to four months, with some patients achieving acceptable visual results and others requiring subsequent surgery.1 The rethinking of hydrops treatment grew out of an observation taken from cataract surgery: When the Descemet membrane is detached after surgery, ophthalmologists have been using intracameral injections of air to reattach the membrane to the corneal stroma. In hydrops, there is a break in the Descemet membrane that allows aqueous humor to enter the stroma. Could an injected air bubble act as a tamponade to prevent aqueous humor penetration into the stroma? This possibility prompted researchers to try using intracameral air to treat hydrops.2 That approach was followed, in turn, by the use of intracameral injections of sulfur hexafluoride (sf6 gas) gas and perfluor...
