Posterior choroidal effusion occurs in the setting of sudden changes in intraocular pressure which facilitates the influx of fluid in the suprachoroidal space. The reason for sudden intraocular pressure fluctuation can be due to varied causes such as filtering surgery, use of antiglaucoma medication. In our case, it was following an uneventful cataract surgery in which the patient presented with a choroidal elevation on the first postoperative day. He was treated with systemic steroids and the choroidal elevation settled in 2 weeks. We present a serial optical coherence tomography imaging of the patient which showed a resolution.

  Introduction Top

Choroidal effusion[1] occurs when the fluid collects in the suprachoroidal space,[2] which is a potential space between the choroid and the sclera. The primary cause of choroidal effusion[3] and hemorrhage is low intraocular pressure (IOP), although inflammation can sometimes play a role. Other risk factors include anticoagulation, aphakia, high myopia, prior ocular surgery, hypotony, straining, hypertension, and heart and respiratory disease.

  Case Report Top

A 72-year-old male underwent uneventful cataract surgery with implantation of hydrophobic IOl. He was a known patient with primary open angle glaucoma on medical treatment with prostaglandin analog. He presented with a blurred vision on the first postoperative day after uneventful cataract surgery. Intraoperatively, the surgeon had experienced a tense eye ball during the final stages of nuclear emulsification and completed the case uneventfully with implantation of hydrophobic intraocular lens. On examination, the best-corrected visual acuity in the right eye was 6\60. No improvement with pinhole. Anterior segment examination RE reveals a well-placed IOL in the capsular bag. The anterior chamber depth was normal. Fundus revealed an enlarged cup-disc ratio of 0.7 a dome-shaped swelling in the posterior pole in the right eye. Examination of the other eye was normal with 6/6 vision an optical coherence tomography (OCT) imaging of the macula revealed a dome-shaped elevation with a convexity at the macula with a shallow subretinal fluid [Figure 1]. The elevation was located only in the posterior pole in the macular region. There was no choroidal thickening in ultrasound B-scan. There was no disc swelling. An angiogram revealed no leakage or hyperflurescence. The patient was started on oral steroid 1 mg/kg body weight. After 7 days, the patient had symptomatic improvement of vision to 6/24 in the right eye. The dome-shaped elevation gradually receded and the convexity had decreased considerably [Figure 2]. The subretinal fluid in the posterior pole and macula had considerably decreased. After 14 days, the BCVA had improved to 6/6. The elevation had subsided in the posterior pole. OCT revealed no subretinal fluid and normal organization of the choroid and retinal layers [Figure 3].

  Discussion Top

The primary cause of choroidal effusion and hemorrhage is low IOP, although inflammation can sometimes play a role. If a choroidal effusion, outcomes can be good with prompt recognition and management. The key is to prevent a posterior choroidal effusion from developing into supra choroidal hemorrhage if left untreated which can become a potential visually significant problem.

Patients with nanophthalmos, choroidal hemangioma, carotid cavernous fistula, Sturge − Weber syndrome, and other conditions associated with increased episcleral venous pressure are also predisposed to choroidal effusion and hemorrhage. Intraoperatively, the surgeon may notice a decreased red reflex 3 and positive posterior pressure causing shallowing of the anterior chamber. The patient may note an increased intensity of pain. In our patient, there was a tense eye intraoperatively after the implantation of the intraocular lens. The surgeon immediately had noticed and closed the wound. The most important step in the management of choroidal effusion is to recognize intraocular pressure fluctuation and close the incision as quickly as possible. In this case, the presence of preexisting glaucoma and sudden intraocular pressure change intraoperatively resulted in choroidal elevation in the posterior pole. This was a reported case of posterior choroidal effusion presenting with posterior pole elevation after uneventful cataract surgery which resolved with steroids.
