Abstract:
There are various treatments for cystoid macular edema (CME) secondary to retinitis pigmentosa (RP); however, the evidence for these treatments has not been previously systematically reviewed. Our review that includes 23 studies shows that oral carbonic anhydrase inhibitors (CAI) (including acetazolamide, methazolamide) and topical CAI (dorzolamide and brinzolamide) are effective first line treatments. In patients unresponsive to CAI treatment, intravitreal steroids (triamcinolone acetonide and sustained-release dexamethasone implant), oral corticosteroid (Deflazacort), intravitreal anti-vascular endothelial growth factor agents (ranibizumab and bevacizumab), grid laser photocoagulation, pars plana vitrectomy, or ketorolac were also effective in improving CME secondary to RP. Oral acetazolamide has the strongest clinical basis for treatment and was superior to topical dorzolamide. Rebound of CME was commonly seen in the long term, regardless of the choice of treatment. Oral acetazolamide should be the first line treatment in CME secondary to RP. Topical dorzolamide is an appropriate alternative in patients intolerant to adverse effects of oral acetazolamide. More studies are required to investigate the management of rebound CME.
