Research progress of pseudophakic cystoid macular edema / 国际眼科杂志(Guoji Yanke Zazhi)

@#Cataract is the most common blinding eye disease in our country. Cataract phacoemulsification combined with intraocular lens implantation is the first choice for cataract surgery, with advantages of a small incision, mild anterior chamber reaction, repaid recovery and small astigmatism of corneal. However, there are still some patients failed to achieve ideal visual quality after surgery due to various reasons even if the surgery is successful. Cystoid macular edema(CME)is one of the common complications in pseudophakic eyes affecting postoperative visual quality after cataract surgery. Recent studies on pseudophakic cystoid macular edema(PCME)are reviewed in this paper.

Acute bilateral Irvine-Gass Syndrome following uneventful cataract surgery in a patient without systemic risk factors / Síndrome de Irvine-Gass aguda bilateral após cirurgia de catarata sem complicações em paciente sem fatores de risco sistêmicos

Abstract We herein report a patient without risk factors who presented acute bilateral Irvine-Gass syndrome after uneventful phacoemulsification. The novelty of our case lies on the fact that the patient presented acute bilateral Irvine-Gass syndrome without a predisposing systemic disease. Even though Cystoid Macular Edema (CME) was somehow expected in the first eye because of the ocular history of trauma, prophylactic measures were not strong enough to avoid its development. Furthermore, those measures could not avoid developing CME in the second eye. A 44-years-old male who underwent cataract surgery in both eyes presented bilateral Irvine-Gass syndrome. Despite prophylactic measures, both eyes developed CME after uneventful cataract surgery. Regular treatment options could not solve the situation and intravitreal Anti-VEGF injections were needed. Bilateral cases of Irvine-Gass Syndrome are rare and generally associated with systemic risk factors. Patients who developed CME following their first cataract surgery should be counseled about the risks of developing the condition following surgery on the contralateral eye. On top of that, aggressive prophylactic measures should be encouraged to prevent CME in these cases.

Resumo Relatamos aqui um paciente sem fatores de risco que apresentou síndrome de Irvine-Gass bilateral aguda após facoemulsificação sem intercorrências. A novidade do nosso caso reside no fato de o paciente apresentar síndrome de Irvine-Gass bilateral aguda sem doença sistêmica predisponente. Embora o Edema Macular Cistoide (EMC) fosse de alguma forma esperado no primeiro olho por causa do histórico ocular de trauma, as medidas profiláticas não foram suficientemente fortes para evitar seu desenvolvimento. Além disso, essas medidas não puderam evitar o desenvolvimento de EMC no segundo olho. Homem de 44 anos submetido a cirurgia de catarata em ambos os olhos apresentou síndrome de Irvine-Gass bilateral. Apesar das medidas profiláticas, ambos os olhos desenvolveram EMC após a cirurgia de catarata sem intercorrências. As opções de tratamento regular não conseguiram resolver a situação e foram necessárias injeções intravítreas de Anti-VEGF. Casos de Síndrome de Irvine-Gass bilateral são raros e geralmente associados a fatores de risco sistêmicos. Os pacientes que desenvolveram EMC após a primeira cirurgia de catarata devem ser avisados sobre os riscos de desenvolver a doença após a cirurgia no olho contralateral. Além disso, medidas profiláticas agressivas devem ser incentivadas para evitar a EMC nesses casos.
