Comparative study of the efficacy and safety of bromfenac, nepafenac and diclofenac sodium for the prevention of cystoid macular edema after phacoemulsification.

AIM: To compare the efficacy, tolerability and safety of bromfenac 0.09%, nepafenac 0.1% or diclofenac 0.1% for the prophylaxis of the cystoid macular edema (CME) after phacoemulsification. METHODS: Group sequential observational comparative study. After phacoemulsification, patients received two months for topical treatment of either diclofenac sodium, bromfenac or nepafenac. All patients received concomitant topical tobramycin 0.3% and topical prednisolone 1%. We measured CME using optical coherence tomography (OCT) central foveal thickness, macular thickness and total macular volume. RESULTS: We enrolled 243 patients from January to June 2015, and 35% received diclofenac, 32.9% bromfenac and 32.1% nepafenac. When we compared pre-operative to three weeks to two months, bromfenac was more effective in reducing foveal volume (21.3 and 35.4 mm3, respectively), compared with the diclofenac (1.3 and 11.5 mm3, respectively), and the nepafenac group, became more edematous 6.4 and 5.3, respectively. Totally 133 patients completed the post-surgical satisfaction questionnaire. Patients complained of eye stickiness in 13.8% whom we gave nepafenac, versus 10.3% whom we gave diclofenac sodium, and in 0 whom we gave bromfenac. CONCLUSION: Bromfenac is the best tolerated and is more effective than diclofenac and nepafenac in reducing CME after phacoemulsification.

Desprendimiento de retina exudativo como primera manifestación de una preeclampsia grave / Serous retinal detachment as a first sign of severe preeclampsia

El desprendimiento de retina exudativo es una causa poco común de pérdida visual en la preeclampsia. Su patogenia no es del todo conocida, aunque la isquemia coroidea pudiera jugar un papel fundamental. Existen pocos casos reportados en la literatura y la mayoría hace referencia a casos aislados o series cortas de casos. Presentamos el caso de una primigesta de 34 años en el tercer trimestre de embarazo con un desprendimiento de retina exudativo bilateral. La sintomatología visual fue la primera manifestación de una preeclampsia que terminó en cesárea de urgencia. La clínica oftalmológica se resolvió de forma espontánea a las dos semanas de la cesárea(AU)

Exudative retinal detachment is an uncommon cause of loss of visual acuity in preeclampsia. Its pathogenesis is not fully understood, but choroidal ischaemia is known to play a key role. Few cases have been reported, and most of these refer to isolated cases or short series of cases. We describe the case of a primigravida aged 34 years, in the third trimester of pregnancy, with bilateral exudative retinal detachment. The visual symptoms were the first manifestation of preeclampsia, which finally required an emergency caesarean section. The retinal detachment resolved spontaneously within two weeks of the caesarean section(AU)
