Study of acute intraoperative suprachoroidal hemorrhage.

Acute intraoperative suprachoroidal hemorrhage or effusion (AISH) was studied in a prospective manner over the past three years. In a general cataract surgery population of 2,523 patient eyes, 15 (0.6%) experienced an AISH. Results of a specific surgical management technique are presented. Surgical control of the AISH consisted of immediate closure of the incision and application of pressure directly to the eye. This tamponades the effusion or hemorrhage, which allows coagulation and completion of the case. There was no attempt to drain the suprachoroidal space. All cases were completed the same day, usually within an hour. The postoperative visual acuities were quite good--20/40 or better in 93% of cases. Factors contributing to AISH were 4+ brunescent nuclear sclerosis, the large incision used with nucleus expression extracapsular cataract extraction, and the combination of anticoagulation and systemic vascular disease.     

The evaluation of incidence of massive suprachoroidal hemorrhage n the material of the Department of Ophthalmology,Medical Academy in Bialystok from 1990 to 2000

PURPOSE: Massive suprachoroidal hemorrhage is a well-known, possibly serious complication of many surgical procedures, including cataract extraction, glaucoma-filtering procedures, penetrating keratoplasty, retinal detachment surgery and pars plana vitrectomy. The aim of our study is evaluation of the incidence of massive suprachoroidal hemorrhage among patients operated in Department of Ophthalmology, Medical Academy in Bia?ystok from 1990 to 2000. MATERIAL AND METHODS: From 1990 to 2000, 6225 intraocular operations, including 5541 cataract extractions, 195 glaucoma-filtering surgeries, 438 retinal detachment surgeries and 51 multiprocedure surgeries were performed. The criteria for diagnosis were the intraoperative signs of suprachoroidal hemorrhage (shallowing of the anterior chamber, increasing of the intraocular pressure, iris prolapse, expulsion of the lens and vitreous, retinal and choroidal elevation and loss of the red reflex) and postoperative ultrasonic examination. RESULTS: 18 eyes were identified with massive suprachoroidal hemorrhage, including 16 eyes during cataract extraction and 2 eyes during filtering procedures. The incidence of suprachoroidal hemorrhage for all intraoperative surgeries was 0.29%. It occurred in 0.28% of cataract surgeries and 1.02% of glaucoma filtering procedures. There were no incidence of suprachoroidal hemorrhage during retinal detachment surgeries. CONCLUSION: A massive suprachoroidal hemorrhage is a relatively rare complication of intraocular operations. Most frequently it is associated with glaucoma filtering surgery.     

Schwere intra- und postoperative suprachorioidale Blutungen

BACKGROUND: The aim of this study was to analyze risk factors, therapeutic strategies, and functional and anatomic results of eyes with severe suprachoroidal hemorrhage. PATIENTS: Eight of 11 bleeding episodes occurred intraoperatively and 3/11 postoperatively. Bleeding was associated with the following surgical procedures: perforating keratoplasty (5x), extracapsular cataract extraction (3x), pars plana vitrectomy (2x), intracapsular cataract extraction (1x). RESULTS: Nine operations were performed with general anesthesia, two after retrobulbar injection. Ocular risk factors (e.g., prior operations, ocular diseases) and general risk factors (e.g., cardiovascular diseases, diabetes) were analyzed. At the end of the follow-up time visual acuity had improved in three eyes, and it was unchanged in one eye and worse in seven eyes. Four eyes were amaurotic; two of them had to be enucleated. CONCLUSIONS: In spite of using state-of-the-art surgical techniques the prognosis of suprachoroidal bleeding remains serious. Patients who have a combination of several ocular and general risk factors almost exclusively are the ones who afflicted by this complication.     

Suprachoroidal bleeding: review and description of eight cases

INTRODUCTION: Suprachoroidal hemorrhage (SCH) is a dramatic complication of intraocular surgery that can result in total loss of vision. METHODS: The records of eight cases of SCH during cataract surgery were reviewed. Six of eight patients were treated by combined radial sclerotomies for suprachoroidal drainage and vitrectomy. Risk factors, therapeutic strategies, and functional and anatomical results were analyzed. RESULTS: The incidence of SCH was 0.45%. Preoperative visual acuity of all eyes suffering from SCH was limited to the perception of light. Postoperatively, six patients showed an increase in visual acuity greater than 0.1; one patient achieved 0.5. Ocular and general risk factors (ocular hypotony, myopia, Valsalva-type maneuvers, intraoperative systemic hypertension) and surgery complications were analyzed. CONCLUSIONS: In spite of using state-of-the-art surgical techniques, the prognosis of SCH remains serious, with a poorer outcome associated with increasing complications due to hemorrhage. Secondary treatment combining radial sclerotomies and vitrectomy should be performed to minimize the damaging effect of choroidal hemorrhage.     

Suprachoroidal hemorrhage during pars plana vitrectomy

Suprachoroidal hemorrhage is an uncommon but serious complication of pars plana vitrectomy that can be associated with a guarded visual prognosis. Risk factors for development of suprachoroidal hemorrhage during pars plana vitrectomy include high myopia, history of previous retinal detachment surgery, rhegmatogenous retinal detachment, use of cryotherapy, scleral buckling at the time of pars plana vitrectomy, external drainage of the subretinal fluid, intraoperative systemic hypertension, and bucking during general anesthesia. In eyes with suprachoroidal hemorrhage during pars plana vitrectomy, the final visual and anatomic outcomes may be compromised by persistent retinal detachment, secondary glaucoma, and ocular hypotony. In most cases, intraoperative drainage of suprachoroidal hemorrhage is not associated with a better outcome. The prognosis is more favorable if the suprachoroidal hemorrhage is localized and does not extend in to the posterior pole.     

Secondary intraocular lens implantation in eyes that experienced suprachoroidal hemorrhage during primary cataract surgery

Six eyes that experienced acute intraoperative suprachoroidal hemorrhage or effusion (AISHE) during primary extracapsular cataract surgery have had secondary lens implantation. All secondary procedures were without recurrent AISHE and uneventful. The six patients achieved 20/30 or better corrected visual acuity. The key to these good results was the maintenance of an intact posterior capsule at the time of original surgery. This was accomplished with early rapid wound closure and no choroidal drainage.     

Massive suprachoroidal hemorrhage during pars plana vitrectomy associated with Valsalva maneuver

PURPOSE: To report the intraoperative occurrence of massive intraocular suprachoroidal hemorrhage associated with Valsalva maneuver. METHODS: Retrospective, multicenter study of patients who developed massive choroidal hemorrhage associated with Valsalva maneuver during vitrectomy. RESULTS: Massive intraoperative suprachoroidal hemorrhage in seven patients (seven eyes) involved three men and four women with a median age of 52 years (range, 26 to 82 years). General anesthesia was used in six of seven cases. Coughing or "bucking" on the endotracheal tube during general anesthesia or severe coughing during the one vitrectomy performed under local anesthesia was associated with massive suprachoroidal hemorrhage. In five of seven eyes, this occurred near the end of surgery, after air-fluid exchange but before sclerotomy closure. Scleral plugs were immediately placed, and sclerotomy closure was performed exigently. Immediate posterior sclerotomy was performed on five of seven eyes; an additional patient underwent posterior sclerotomy postoperatively. After median follow-up of 18 months (range, 3 to 36 months), final visual acuity was no light perception in four eyes, light perception in one eye, 20/250 in one eye, and 20/20 in one eye. Four eyes became phthisical. CONCLUSIONS: Valsalva maneuver during pars plana vitrectomy may result in massive suprachoroidal hemorrhage with disastrous visual consequences. Precautionary measures to prevent coughing or "bucking" on the endotracheal tube during general anesthesia, or a prolonged episode of coughing during local anesthesia, may prevent this potentially devastating complication.     

The risk factors for massive suprachoroidal hemorrhage in the material of the Department of Ophthalmology,Medical Academy in Bialystok from 1990 to 2000

PURPOSE: The aim of our study is evaluation of the risk factors for development of expulsive hemorrhage among patients operated in Department of Ophthalmology, Medical Academy in Bia?ystok from 1990 to 2000. MATERIAL AND METHODS: This was a retrospective study of 18 patients with massive suprachoroidal hemorrhage occurring in association with cataract and glaucoma surgery. RESULTS: The mean age of patients with expulsive hemorrhage was 69.5 years. There were 10 women (55.6%) and 8 men (44.4%). In the population of patients in whom the suprachoroidal hemorrhage occurred hypertension was present in 5 (27.7%) and diabetes in 3 (16.6%). 8 patients (44.4%) had reported atherosclerotic cardiovascular disease. 7 patients (38.8%) had a history of glaucoma, 6 (33.3%) had high myopia. 1 patient had posterior synechiae after uveitis. All surgeries, except one, were performed under local anesthesia. There were no associations between suprachoroidal hemorrhage development and season. CONCLUSION: The results of our study suggest, that the risk factors for the development of massive intraoperative suprachoroidal hemorrhage are: high myopia, glaucoma and systemic cardiovascular diseases. A knowledge of these risk factors can help the physician in identifying patients, who are at a greater risk of having massive suprachoroidal hemorrhage.     

A new approach towards pathogenesis and treatment of massive suprachoroidal hemorrhage

A massive suprachoroidal hemorrhage is a well-known, possibly serious complication of a variety of surgical procedures such as cataract extraction, penetrating keratoplasty, glaucoma-filtering operation, retinal detachment surgery and pars plana vitrectomy. It is defined as a hemorrhage, in the suprachoroidal space, of sufficient volume either to cause extrusion of intraocular contents outside of the eye or to force the inner retinal surfaces into apposition ("kissing"). Despite surgical interventions to drain the hemorrhage and establish normal anterior and posterior anatomic configurations to return of preoperative visual acuity is hard to prognosticate. This paper presents the current knowledge on the pathogenesis, risk factors, treatment of massive suprachoroidal hemorrhage.     

Vitrectomy for nondiabetic vitreous hemorrhage. Not associated with vascular disease

Forty-nine consecutive eyes with nonclearing vitreous hemorrhage not associated with retinal or choroidal vascular disease underwent vitrectomy. Etiologies included vitreous hemorrhage during anterior segment surgery (22 eyes), blunt trauma (8 eyes), retinal tears with and without retinal detachment (8 eyes), Terson's syndrome (2 eyes), avulsed retinal vessel (1 eye), and idiopathic cases (8 eyes). The final visual acuity improved in 48 eyes (98%). Follow-up was 6-91 months (mean, 20 months). Of the 49 eyes, 40 eyes (82%) had a best postoperative visual acuity of 20/100 or better, 31 eyes (63%) had visual acuity of 20/40 or better, and 12 eyes (24%) had visual acuity of 20/20. The major complications included intraoperative iatrogenic retinal breaks (5 eyes), postoperative progressive cataract (7 eyes), late retinal detachment (4 eyes) and recurrent vitreous hemorrhage (2 eyes). The major complication associated with later visual loss was progressive cataract.     

Mature cataracts increase risk of capsular complications in manual small-incision cataract surgery of pseudoexfoliative eyes

BACKGROUND: To evaluate rates of intraoperative posterior capsule complications in manual small-incision cataract surgery of eyes with and without pseudoexfoliation syndrome in terms of cataract maturity level. METHODS: We identified patients who had undergone manual small-incision cataract surgery between January 1997 and October 2003 from a review of patient charts. Preoperative data collected were cataract maturity level, best corrected visual acuity, and intraoperative posterior capsule complications as documented in the surgical report, namely (1) posterior capsule rupture or zonulolysis, or both, and (2) vitreous loss. RESULTS: Two hundred and twenty-five eyes of 187 patients met the study criteria, of which 99 eyes had pseudoexfoliation syndrome (group 1) and 126 did not (group 2). Intraoperative posterior capsule complications occurred in 18 eyes (18%) in group 1 and 7 eyes (5.5%) in group 2 (difference was significant at p=0.003). The rate of capsular complications was significantly higher in both groups for eyes with preoperative visual acuity worse than 20/200 than for eyes with 20/200 or better. The number of eyes with visual acuity worse than 20/200 (counting fingers, hand motion, or light perception) was 70 (70%) in group 1 and 63 (50%) in group 2. Mature or brunescent cataract occurred in 49.5% of group 1 eyes and 26% of group 2 eyes. INTERPRETATION: In manual small-incision cataract surgery, pseudoexfoliation syndrome has an increased intraoperative posterior capsule complication rate that increases as the level of cataract maturity increases and the preoperative visual acuity decreases.     

Suprachoroidal hemorrhage after glaucoma filtering surgery

We reviewed a series of 305 consecutive glaucoma filtering procedures performed by one surgeon. Five eyes (1.6%) had a postoperative suprachoroidal hemorrhage. All five eyes were aphakic, and four had undergone a partial or complete vitrectomy before the glaucoma surgery. The incidence of this complication was 13% (five of 37) among the aphakic eyes and 33% (four of 12) in the aphakic, vitrectomized eyes in this series. Despite drainage of the hemorrhage and reformation of the anterior chamber, three patients had a poor visual outcome.     

Delayed suprachoroidal hemorrhage after glaucoma filtration procedures

OBJECTIVES: To determine the incidence of, risk factors for, and outcomes of delayed suprachoroidal hemorrhage (DSCH) after glaucoma filtration surgery. DESIGN: Retrospective case-control study. PARTICIPANTS: All patients undergoing glaucoma filtration procedures between 1986 and 2000 at Indiana University who were diagnosed postoperatively with suprachoroidal hemorrhage. A total of 66 patients with DSCH were identified. These were compared with a randomly selected group of patients who underwent similar procedures but did not have suprachoroidal hemorrhage. METHODS: Total cases of DSCH were initially compared with the total number of glaucoma surgeries to determine the overall incidence and the incidence in the different procedures. Subsequently, a case-control study was performed comparing the group with hemorrhage to the control group to identify risk factors. Finally, outcomes and prognostic factors were determined by comparing vision preoperatively and postoperatively and parameters of patients with good and poor outcomes. MAIN OUTCOME MEASURES: Incidence of DSCH, risk factors associated with its occurrence, visual outcomes, and factors important for prognosis. RESULTS: Of a total of 2285 glaucoma filtration procedures, 66 (2.9%) cases of DSCH were identified. It developed in 9 of 615 (1.5%) trabeculectomies without antimetabolite, 30 of 1248 (2.4%) trabeculectomies with antimetabolite, 2 of 72 (2.8%) valved tube shunt implantations, and 25 of 350 (7.1%) nonvalved tube shunt implantations. The increased incidence of DSCH after tube shunts compared with trabeculectomy-associated DSCH was significant (P < 0.0001) with an odds ratio of 3.2. The risk factors for DSCH after glaucoma surgery include white race (P = 0.012), anticoagulation (P = 0.034), severe postoperative hypotony (P = 0.033), and aphakia/anterior chamber intraocular lens (P = 0.002). The visual outcomes of patients with hemorrhage were poor, with a decrease in logarithm of the minimum angle of resolution visual acuity from 0.72 to 1.36, which was statistically significant compared with the controls (P < 0.009). CONCLUSIONS: Delayed suprachoroidal hemorrhage occurs more frequently after tube shunt implantation than after trabeculectomy. Caution should be exercised when operating on patients with known risk factors, because the visual outcomes after DSCH are poor.     

Risk factors of massive suprachoroidal hemorrhage during extracapsular cataract extraction surgery

PURPOSE: To estimate retrospectively the incidence, predisposing factors, and possible mechanisms precipitating massive suprachoroidal hemorrhage (MSCH) development during cataract extraction surgery. METHODS: The study was conducted on 6639 consecutive cataract extractions performed between 1994 and 2002. All of the procedures were carried out using traditional nucleus expression methods. The study cases comprised 19 patients who developed intraoperative MSCH. The remaining 6620 patients served as the control group. Baseline systemic and ocular characteristics, as well as intraoperative factors, were analyzed. Categorical variables were analyzed using the chi-square test and the Fisher exact test. RESULTS: The incidence of MSCH during cataract surgery was 0.28%. Highly significant risk factors included high myopia, glaucoma, and diabetes (p<0.01). Atherosclerotic vascular diseases and/or hypertension were less significantly related to the condition (p<0.05). There was no significant relationship between MSCH formation and age, sex, side of the cataract, history of ocular trauma, or inflammation. The incidence of MSCH did not differ between patients operated on with extracapsular or intracapsular cataract extraction. CONCLUSIONS: Attention to multiple preoperative and intraoperative ocular and systemic variables may allow the identification of, and prophylaxis for, patients at greater risk for MSCH.

Surgical management of suprachoroidal haemorrhages induced by cataract surgery--case series

Purpose: Suprachoroidal hemorrhage (SCH) is a rare complication occurring during surgery (early SCH) or 3-5 days after operation as a delayed suprachoroidal hemorrhage. It occurs more often in patients who have complicated cataract surgery with vitreous loss or lens dislocation. The purpose of this study was to present surgical treatment of 7 patients with suprachoroidal hemorrhage due to cataract surgery. Material and methods: Mean age of patients was 72,4 years old. There were 3 female and 4 male. Six patients were operated using phacoemulsification, one patient- using ECCE. In 3 cases the vitreous loss and lens dislocation occurred during operation. Results: Suprachoroidal drainage was performed in 4 patients. In 3 patients suprachoroidal drainage was followed by vitrectomy. In this group in 2 patients injection of silicone oil was done. Anterior infusion line was used in all cases. Drainage sclerotomies were created in the quadrants of the involved SCH, confirmed by ultrasonography. In all treated patients reattachment of the choroid was obtained. The visual acuity improved significantly (final v. a. was between 0. 02 and 0. 5). Conclusions: According to our observation, the implementation of the suprachoroidal drainage combined with vitrectomy might improve the prognosis and facilitate the achievement of functional vision.     

Massive suprachoroidal hemorrhage: secondary treatment and outcome

PURPOSE: Massive suprachoroidal expulsive hemorrhage (SCH) is a dramatic and devastating intraocular complication of intraocular surgery and trauma that can result in total loss of vision. The aim of our study was to present the results of secondary surgical treatment of eyes following massive SCH. PATIENTS AND METHODS: We treated 10 patients suffering from massive SCH by combined radial sclerotomies for suprachoroidal drainage and vitrectomy with use of perfluorocarbon and instillation of silicone oil. We analyzed the clinical characteristics, visual acuity and anatomical status before and after secondary treatment. RESULTS: Visual acuity of all eyes suffering from SCH was light perception. Postoperatively five patients with SCH showed either no improvement of function or visual acuity of counting fingers. An increase in visual acuity to maximal 0.1 was seen in four eyes; one patient achieved 0.6. With a minimum of 6 months' follow-up, four eyes developed hypotony, two eyes became phthisical, and in two eyes recurrent traction retinal detachment occurred. CONCLUSIONS: Secondary treatment by combined suprachoroidal drainage by sclerotomies and vitrectomy should be performed to minimize the damaging effect of choroidal hemorrhage.     

Expulsive hemorrhage in cataract extraction

This article reports on six cases of massive expulsive hemorrhage during intracapsular cataract extraction (incidence = 0.17%). Some of the known risk factors are old age, hypertony, glaucoma, and an insufficient decrease in intraocular pressure following oculopression prior to surgery. Drainage of the suprachoroidal hemorrhage, closure of the wound and reformation of the anterior chamber are necessary surgical interventions. In one case the treated eye was saved and a visual acuity of 0.1 achieved.     

Rhegmatogenous retinal detachment associated with massive spontaneous suprachoroidal hemorrhage and prognosis of pars plana vitrectomy

AIM:To describe the clinical characters of rhegmatogenous retinal detachment (RRD) associated with massive spontaneous suprachoroidal hemorrhage (SSCH). To evaluate optimal timing and prognosis of pars plana vitrectomy.METHODS: A retrospective review of 6 cases (6 eyes) of RRD and massive SSCH among 3772 cases of RRD was conducted. All of 6 patients were treated with twenty-gauge vitrectomy, suprachoroidal blood drainage, phacoemulsification (PHACO) or lensectomy and silicon oil tamponade. The clinical characters, intraoperative findings and treatment outcomes were reported.RESULTS: In the 6 affected eyes of 6 patients (3 men and 3 women; mean age, 53.83y; range 34-61y), preoperative visual acuity ranged from faint light perception (LP) to counting finger (CF). The average interventional duration from visual decreased to surgery was 12.8 d (range 9-15d). All eyes were associated with high myopia and the mean ocular length was 30.32 mm (range 28.14-32.32 mm). Choroidal hemorrhage were successfully drained in the operation of all 6 eyes. Intraoperative findings showed there were multiple retinal breaks in all 6 eyes and in 4 eyes breaks were along supratemporal and/or infratemporal retinal vascular arcade, especially in the edge of chorioretinal atrophy areas. These patients were followed up from 6 to 34mo (Mean, 23.5mo). The best-corrected visual acuity after surgery varied from CF to 20/100, with improvement in 5 eyes (83.33%) and no change in 1 eye (16.67%). Ocular hypertension ocurred in 1 eye (16.67%), which was successfully treated by silicon oil removal combined with trabeculectomy. In 4 eyes, tractional retinal detachment caused by proliferative vitreoretinopathy (PVR) appeared and a secondary surgery of pre-retinal membrane peeling and silicon oil retained were performed. In 4 eyes, silicon oil cannot be removed. The initial and final reattachment rates were 33.33% and 66.67%, respectively.CONCLUSION: RRD associated with massive SSCH is an extremely rare event. The most common risk factor is long axial length. Vitrectomy and choroidal blood drainage can effectively remove suprachoroidal hemorrhage and promote retinal reattachment in these eyes. However, silicon oil could not be removed in most eyes and final visual acuities are generally poor.
