Acute intraoperative choroidal effusion.

We studied five cases of acute choroidal effusion that occurred during intraocular surgery and one case of a localized choroidal hemorrhage. Acute intraoperative choroidal effusion is a poorly recognized surgical complication and may precede expulsive hemorrhage in many cases. The treatment is immediate closure of the wound, after which the intraocular pressure may rise to 80 mm Hg or more. However, the pressure will return to normal after 15 to 30 minutes and the area of effusion will remain localized. Scleral puncture to drain fluid is not indicated if the wound can be closed before there is a prolapse of the iris or other intraocular tissues.

Expulsive choroidal effusion. A complication of intraocular surgery.

Massive serous choroidal effusion may occur as an expulsive complication of intraocular surgery. The pathophysiology of expulsive hemorrhage involves rupture of the short posterior ciliary arteries, while that of effusion involves massive exudation through the walls of the choroidal vessels. Many of the predisposing factors may be shared including atherosclerosis, hypertension, and sudden surgical decompression. The treatment of both entities is the same--swift closure of the wound, drainage of suprachoriodal blood or effusion through a posterior sclerotomy site, and injection of a physiologic solution into the anterior chamber to tamponade the leaking vessels and restore normal intraocular anatomic relationships. The visual prognosis following expulsive choroidal effusion is much more favorable than that of expulsive hemorrhage.

Choroidal effusions in two patients with glomerulonephritis.

Two patients with renal disease and choroidal effusions are presented. The renal disease was mediated by humoral immunologic mechanisms as demonstrated by immunofluorescent studies of renal biopsies. Experimental and clinical studies provided evidence of simultaneous immune-complex deposition in both the renal glomerulus and the uvea of the eye. Immune-mediated vascular damage may result in glomerulonephritis and choroidal effusions.

Tears of the retinal pigment epithelium: occurrence in association with choroidal effusion.

Two patients developed large tears of the retinal pigment epithelium associated with choroidal effusion. One tear occurred after combined cataract/filtration surgery complicated by postoperative choroidal detachment; the second developed in a patient with idiopathic uveal effusion syndrome. Weakness of the junctions of the pigment epithelial cells secondary to the accumulation of fluid in the subretinal or suprachoroidal space may result in tearing of the retinal pigment epithelium as it is stretched.

Choroidal effusion during glaucoma surgery in patients with prominent episcleral vessels.

Rapid intraoperative choroidal effusion and flattening of the anterior chamber occurred during glaucoma filtering surgery in four young patients with prominent episcleral vessels, elevated episcleral venous pressure, and advanced open-angle glaucoma. Two of these four patients had Sturge-Weber syndrome. Intraoperative release of suprachoroidal fluid (SCF) through a posterior sclerotomy facilitated reformation of the anterior chamber and repositioning of the iris and ciliary body. Posterior sclerostomy performed prior to opening the anterior chamber minimized the above-mentioned untoward series of events. Analysis of SCF and serum demonstrated considerable differences in total protein and individual immunoglobulin levels; this appears to be a manifestation of molecular sieving at the level of the choriocapillaris. Choroidal detachment and postoperative serous retinal detachment are manifestation of this phenomenon.

[Choroid effusion in an antiglaucoma operation in a child with Sturge-Weber syndrome].

The authors describe a case of expulsive choroidal effusion which occurred in the course of a fistulating operation in a child with Sturge-Weber syndrome. This is the youngest patient with this complication so far reported in the literature. The persistent postoperative choroidal and retinal detachments in this case led to a considerable diminution of visual acuity.

Intraocular gas injection in the treatment of cornea-lens touch and choroidal effusion following fistulizing surgery.

Five eyes with large choroidal detachments and flat anterior chambers following fistulizing surgery were treated with injection of perfluoropropane into the anterior chamber. In all cases the choroidal detachments resolved within 4 days, without the need for drainage. Three phakic eyes developed anterior capsular opacification in the area of contact between the gas bubble and the anterior capsule. Injection of perfluoropropane is recommended as a simple and effective approach to the management of choroidal detachments with flat anterior chamber in pseudophakic eyes and in cataractous phakic eyes.

Glaucoma filtering surgery with postoperative 5-fluorouracil in patients with intraocular inflammatory disease.

Twenty-one eyes of 18 patients with uncontrolled glaucoma and intraocular inflammatory disease had glaucoma filtering surgery with postoperative subconjunctival 5-fluorouracil (5-FU). Follow-up for eyes in which intraocular pressure was controlled ranged from 6 to 53 months (mean, 34 months; median, 35 months). Fifteen of 21 eyes (71%) had controlled intraocular pressure (21 mmHg or less). Control was achieved in 9 of 10 (90%) phakic eyes and in 6 of 11 (55%) aphakic or pseudophakic eyes with or without glaucoma medication. Four of six filter failures had a second filtering procedure with 5-FU, and of these four procedures, three were successful. Cataract progression occurred in 9 of 10 phakic eyes, leading to cataract surgery in 7 eyes. Other complications included corneal epithelial defects in 13 eyes, bleb leaks in 3 eyes, choroidal effusions in 13 eyes, 1 choroidal hemorrhage, 1 serous retinal detachment and macular retinal pigment epithelial disturbance associated with hypotony and choroidal effusion. Filtering surgery with postoperative subconjunctival 5-FU can successfully control intraocular pressure in eyes with ocular inflammatory disease.

Serous retinal detachment following glaucoma filtering surgery.

We report the occurrence of serous retinal detachment in association with choroidal effusion and hypotony in six eyes that had undergone glaucoma filtering surgery. Hypotony with choroidal effusion was documented in five patients before the onset of serous retinal detachment. While one patient underwent vitrectomy, treatment was conservative in the other patients. Serous retinal detachment and choroidal effusions resolved spontaneously as the intraocular pressure normalized. Although one patient regained preoperative visual acuity, all other patients lost at least one line of Snellen acuity.

Magnetic resonance imaging and computed tomography of choroidal detachment.

The magnetic resonance imaging (MRI) and computed tomography (CT) findings in 9 patients with hemorrhagic choroidal detachment, serous choroidal detachment and/or ocular hypotony, choroidal effusion and 6 patients with exudative retinal detachment are described. Subacute hemorrhagic choroidal detachment appeared as moderately hyperintense image in T1 weighted MR scans and as hypointense in T2 weighted scans. Chronic hemorrhagic choroidal detachment was seen as hyperintense image in T1 and T2 weighted scans. Serous choroidal detachment and choroidal effusion appeared as moderately hyperintense image in T1 and T2 weighted scans. The exudative retinal detachment characteristically appeared on MR scans as a dependent hyperintense object in T1 and T2 weighted scans.

Choroidal hematoma and effusion: evaluation with MR imaging.

To evaluate the usefulness of magnetic resonance (MR) imagining in the evaluation of choroidal pathologic conditions, the authors studied 15 patients with either choroidal hematoma or choroidal effusion with a 1.5-T MR imager. These two lesions were reliably distinguished from each other on the basis of MR findings. Choroidal hematomas appeared as lenticular-shaped masses in the wall of the eyeball, and signal intensity depended on the age of the hematoma. Choroidal effusions appeared as crescentic or ring-shaped areas of increased signal on both T1- and T2-weighted images in an anatomic distribution corresponding to the choroidal and suprachoroidal spaces.

Retinal detachment adherent to posterior chamber IOL after Molteno implant surgery.

A patient with refractory glaucoma 1 year after cataract extraction and trabeculectomy had Molteno implant surgery. Three days after surgery a kissing choroidal effusion and retinal detachment adherent to the posterior chamber IOL were detected. Repeated choroidal taps were unsuccessful. Removal of the Molteno implant, vitrectomy, and silicone oil injection were required to reattach the retina.

Silicone tubes in glaucoma surgery: the effect of technical modifications on early postoperative intraocular pressures and complications.

One hundred and nineteen eyes with glaucoma were treated by implantation of silicone rubber tubes draining either to encircling inverted gutters (92 eyes) or to integral plates sutured at the equator of the globe. The occurrence of persistent choroidal effusion was related significantly (S less than 0.01) to post-operative hypotony and choroidal haemorrhage appeared to occur during periods of ocular hypotony. This paper describes our surgical modifications to overcome these problems. A one-piece integral tube and plate with a slit-valve mechanism designed to regulate post-operative intraocular pressure had a very variable response in 27 eyes, with mean pressures similar to those after unligated tube and gutters. Ligation of the tube in 34 eyes caused significantly higher mean intraocular pressures on the first two days after surgery than that in 43 eyes without ligation and the incidence of ocular hypotony (less than 7 mmHg) was significantly lower after ligation. However, five eyes with ligated tubes required operative release of the suture because of uncontrollably raised intraocular pressures. Venting of the drainage tube on the anterior chamber side of the occlusive ligation in 15 eyes caused fewer cases of raised post-operative intraocular pressures, but also a moderate increase in the frequency of ocular hypotony. At present a combination of occlusive ligation and a venting stab into the drainage tube in a one-piece tube and plate system appears to be the best design for avoiding short-term ocular hypotony whilst achieving long-term pressure control.

Uveal effusion following pan-retinal photocoagulation.

Uveal effusion combined with nonrhegmatogenous retinal detachment is presented as a complication of pan-retinal photocoagulation in diabetic patients. This complication is believed to be a direct effect of photocoagulation on the choroidal vasculature. The mechanism is postulated to be secondary to photocoagulation-induced choroiditis, choroidal vascular occlusion, or a combination of the two. Corticosteroid therapy is recommended as being effective in resolving the choroidal effusion.

Choroidal detachment, flat anterior chamber, and hypotony as complications of neodymium: YAG laser cyclophotocoagulation.

Severe hypotony, flat anterior chamber, and serous choroidal detachment after transscleral neodymium: YAG laser cyclophotocoagulation (Nd:YAG-CPC) for three cases of intractable glaucoma are reported. The three patients had failed previous filtering surgery and were receiving maximal medical therapy. The types of glaucomas treated were two cases of primary open-angle and one chronic-angle closure. The complications were noted between 1 and 2 weeks from the time of treatment. One patient improved spontaneously after 1 week of observation. Another patient required drainage of the choroidal effusion and anterior chamber reformation. The last patient remains under observation with a low intraocular pressure (IOP) and a slowly resolving serous choroidal detachment. Though the incidence of shallow anterior chambers is three cases (0.5%) in this series of 750 Nd:YAG-CPCs, it represents a serious problem that had not been reported previously.

Magnetic resonance imaging in the evaluation and differentiation of uveal melanoma.

We evaluated 39 patients with intraocular disease by magnetic resonance imaging (MRI). Malignant uveal melanoma was considered the likely diagnosis in 25 patients. Seventeen patients underwent surgery, and the histopathologic diagnosis of melanoma was confirmed. The authors observed that uveal melanomas had characteristic MRI features consisting of a relatively high-signal intensity in T1-weighted images and a relatively low-signal intensity in T2-weighted images. These images reflected their inherently relative short T1 and T2 relaxation times. Choroidal lesions elevated more than 3 mm were well visualized on MRIs. MRI also proved valuable for differentiating uveal melanoma from associated subretinal effusion, choroidal hemangioma, choroidal metastasis, and hemorrhagic and serous choroidal detachments.

Morbidity following prolonged postoperative hypotony after trabeculectomy.

The postoperative course of a series of 54 patients that had undergone primary trabeculectomy for open-angle glaucoma is reviewed. Almost one third of the eyes had prolonged postoperative hypotony with an intraocular pressure less than 8mm Hg for more than 2 weeks. The possible significance of prolonged hypotony and choroidal effusions is discussed in relation to the final intraocular pressure and the effect on visual acuity.
