[Prognosis of surgery in epimacular membranes after retinal break or rhegmatogenous retinal detachment].

INTRODUCTION: The prognosis of the formation of epiretinal membranes after retinal break or rhegmatogenous retinal detachment, treated or not treated, does not seem as favorable as that of the idiopathic membranes, but has not yet been extensively studied. Our goal was to analyze the functional result and the retinal complications of the treatment of these membranes. METHODS: The retrospective study deals with a consecutive series of 28 patients operated on for epimacular membranes, with a minimum follow-up of 3 months. The outcome measures were the postoperative visual acuity at 3-6 months compared with the preoperative visual acuity, taking into account the condition of the crystalline lens as well as the incidence of membrane recurrence and new or recurrent retinal detachment. RESULTS: A 2-line or more visual improvement was achieved in 57% of the cases (16/28), i.e., 36% of eyes with progressive cataract (4/11), 50% of primary pseudophakic eyes (3/6), and 80% of eyes with unchanged lens (8/10). There was no recurrent epimacular membrane formation, with a mean follow-up of 8.7 months. A new or recurrent retinal detachment was observed in 25% of the cases (7/28). DISCUSSION AND CONCLUSION: These results, compared with those achieved in the treatment of idiopathic membranes, as the literature reports, confirm the fair surgical prognosis of epimacular membrane formation after retinal break or rhegmatogenous retinal detachment.

Aphakic retinal detachment.

A study of 132 cases of aphakic retinal detachment (ARD) following mainly intracapsular cataract surgery has been made. Forty-nine cases (37%) were found to have vitreous incarcerated into the cataract section out of a total of 54 (41%) cases who had suffered a vitreous complication during cataract surgery. A study of the characteristics of ARD reveals that those cases having had a vitreous complication in the management of their cataracts are more likely to develop detachment within three months than those not suffering from such a complication. The occurrence of these early post-extraction retinal detachments is not influenced by the presence of underlying axial myopia. When we compared ARD in patients whose cataract extractions had been complicated by vitreous incarceration with those ARDs following uncomplicated cataract surgery, we found that the characteristics of the detachments were very similar. Thus distribution of underlying myopia, extent of detachment, length of time of detachment, and multiplicity and type of retinal holes were generally similar. However, ARD following complicated cataract surgery is more likely to suffer from periretinal fibrosis. The findings confirmed the risk of ARD following complicated intracapsular cataract surgery and support the tendency to perform the extracapsular operation.

[Clinical features of central retinal vein occlusion complicating exudative retinal detachment].

OBJECTIVE: To investigate the clinical features of central retinal vein occlusion (CRVO) complicating exudative retinal detachment (ERD). METHODS: General health, vision, intraocular pressure, appearance of the fundus and fundus fluorescein angiography (FFA) and the results of ultrasound examination in cases with CRVO complicating ERD were analyzed. RESULTS: Eight patients were male and 7 patients were female. Age of those patients ranged from 18 to 42 years, averaged 25 years. Five cases combined with neovascular glaucoma. Initial vision ranged from 0.05 to light perception. There were notably edema and hemorrhage in the macular region. Extensive exudative appeared at the edge of edema and detachment region. The extent of retinal detachment was 2/12 - 5/12 quadrant at sitting position. No collateral vessels were found on the optic disk. FFA showed extensive blockage by the hemorrhages or capillary nonperfusion. CONCLUSIONS: ERD is a rare and severe complication of CRVO, which usually develops in young patients and combines with neovascular glaucoma. The appearance in fundus and FFA shows a characteristic features.

Healon in retinal detachment with proliferative vitreoretinopathy.

In 73 eyes, retinal detachments complicated by proliferative vitreoretinopathy (PVR) were treated by intravitreal injections of Healon, in addition to scleral buckling procedures. The number of completely reattached retinas three months postoperatively was dependent upon the grade of PVR: 50% were reattached when PVR comprised only one quadrant (Grade C-1); 30% when two to four quadrants were involved (Grade C-2, C-3 and D-1). Reattachment was not achieved in two cases of PVR with funnel-like configurations (D-2). Major complications that could be attributed to Healon did not occur. The results indicate that Healon injections, combined with scleral buckling procedures, are an encouraging approach to retinal detachments with PVR Grades C-2 through D-1.

Concentration of neuron-specific enolase and S100 protein in the subretinal fluid of rhegmatogenous retinal detachment.

BACKGROUND: Neuron-specific enolase and S100 protein are markers of neuronal lysis. To assess the neuronal suffering in rhegmatogenous retinal detachment we quantified neuron-specific enolase and S100 protein in the subretinal fluid. METHODS: The puncture was performed in the sclera with a Merseture 5/0 round needle, and the fluid was collected with a glass capillary tube. Twelve subretinal fluid samples were obtained from 12 eyes with rhegmatogenous retinal detachment undergoing retinal detachment surgery. Vitreous from ten eyes with macular hole or epimacular membrane served as negative control group, and vitreous collected during cornea procurement from ten deceased patients served as positive control group. RESULTS: The mean concentration of neuron-specific enolase (in nanogrammes per millilitre) was 602 in the subretinal fluid of rhegmatogenous retinal detachment, 10.2 in the serum of these patients, 2.9 in the vitreous of the negative control group, and 364 in the positive control group. The mean concentration of S100 protein (in nanogrammes per millilitre) was 104 in the subretinal fluid of rhegmatogenous retinal detachment, <0.1 in the serum of these patients and in the vitreous of the control negative group, and 11.18 in the positive control group. CONCLUSION: Neuron-specific enolase (NSE) and S100 are known to be good markers of brain stress and, thus, are good markers of retinal stress.

[Incidence of cataract and retinal detachment associated with atopic dermatitis].

The incidence of cataract and retinal detachment associated with atopic dermatitis is reported. The subjects suffered from moderate or severe atopic dermatitis. Seventy-five patients (32 male and 43 female, age: 7-46, mean 19.7 years) had their initial examination at the Department of Ophthalmology, Sapporo Medical University Hospital, from 1981 to 1990. Cataract was found in 13 (6 male and 7 female) out of the 75 patients (17.3%). All cases except one already had cataract at the initial visit. The average age was 21.2 years. Nine had bilateral cataracts and four had unilateral. Type of cataract in 22 eyes was anterior subcapsular cataract (n = 3), posterior subcapsular cataract (n = 8), anterior and posterior cataract (n = 9), and mature cataract (n = 2). Retinal detachment was associated in six (8.0%) out of the 75 patients. Four were male and two were female. The average age was 21.6 years (range 18-29). Three cases were bilateral and 3 unilateral. Five of nine eyes with retinal detachment had no history of intraocular surgery. Four of the nine had a history of cataract extraction (3 eyes) and trabeculectomy (1 eye). Tears were observed in 5 out of 9 eyes (small tears in the peripheral retina (n = 1), oral dialysis (n = 3), and breaks at the pars plicata (n = 1). Tears could not be observed in four eyes (44%). Detachment of the pars plana was found in seven eyes. Retinal detachment was always associated with cataract.

Scleral ectasia in rhegmatogenous retinal detachment.

OBJECTIVE: To determine the relation between retinal tears and scleral ectasia. DESIGN: Prospective study. SETTING: University-based referral practice in Montreal. PATIENTS: Fifty-seven consecutive patients with primary rhegmatogenous retinal detachments undergoing scleral buckling surgery. Patients with a history of trauma or previous cryotherapy, laser treatment or other vitreoretinal procedures were excluded. Fifteen patients with diabetes mellitus undergoing primary vitrectomy and prophylactic scleral buckling for nonclearing vitreous hemorrhage constituted the control group. OUTCOME MEASURES: Presence of scleral ectasia, visual acuity, refractive error. RESULTS: Thirty-one of the study patients were phakic and 26 were aphakic or pseudophakic. Fifteen (48.4%) of the phakic patients were found to have scleral ectasia, compared with six (23.1%) of the aphakic/pseudophakic patients and two (13.3%) of the control patients (p < 0.05, chi 2 test). The most frequent location of ectasia was the superotemporal quadrant. Retinal tears occurred in the same quadrant as scleral ectasia in 12 (80.0%) of the phakic patients. CONCLUSIONS: Scleral ectasia may be causally related to rhegmatogenous retinal detachment in certain cases.

The role of the vitreous in retinal detachment surgery with external buckling.

PURPOSE: To prove the role of the vitreous in retinal detachment surgery with scleral buckling procedures, we retrospectively investigated the charts of patients who were operated on for retinal detachment by scleral buckling between January 1995 and June 1997. METHODS: Out of a total of 718 cases, 41 retinal detachments occurred in previously vitrectomized eyes. The buckling procedure consisted of silicone sponge explants in 513 cases (254 radial, 259 circumferential) and of encircling elements in 202 cases. Three eyes received a temporary balloon. The minimal follow-up was 3 months. RESULTS: After primary surgery in the 677 nonvitrectomized eyes, the retina was attached in 482 eyes (71.2%), after reoperation in 627 eyes (92.6%). With up to 3 reoperations (including vitrectomy with gas or silicone oil tamponade in 79 eyes), the final success rate was 98.7%. The corresponding reattachment rates in the 41 vitrectomized eyes were 82.9% after primary surgery and 97.6% after reoperation. Repeated surgery in 6 eyes consisted of successful internal tamponade by silicone oil. The reattachment rates after primary buckle procedure are of most interest to the role of the vitreous: the highest success rate (82.9%) was achieved in the vitrectomized eyes versus 71.2% in the nonvitrectomized eyes. The difference is statistically not significant. CONCLUSIONS: We therefore conclude that the absence of the vitreous has no adverse effect on the results of buckling procedures for retinal detachment. The choice of the surgical technique in treating retinal detachments in vitrectomized eyes should only determined by retinal findings such as the number and extent of breaks or the presence and stage of proliferative vitreoretinopathy.

[Results of treating rhegmatogenous retinal detachment with vitrectomy and silicone oil tamponade].

INTRODUCTION: Silicone oil is used in the treatment of rhegmatogenous retinal detachment when there is a high risk of postoperative proliferative vitreoretinopathy (PVR). This type of internal tamponade can be responsible for serious side effects. Removal of silicone oil is necessary to ensure a long-lasting functional result. The purpose of this study was to evaluate the results of using a transient internal tamponade with silicone oil. PATIENTS AND METHODS: A retrospective review of cases of rhegmatogenous retinal detachment treated with internal tamponade with silicone oil for the first time in a 1-year period (January 2001 to December 2001) was conducted. We studied the type of retinal detachment, treatment before vitrectomy and silicone oil tamponade, indication for silicone oil tamponade, surgical steps and their results, causes of recurrent retinal detachment, and final visual acuity. Anatomical success was defined as a reattached retina after silicone oil removal. RESULTS: Ninety-three patients were included. Anatomical success was achieved, after one or several procedures, in 71 patients (76.3%). The mean total number of surgical procedures was 2.6. After initial surgery, recurrence of retinal detachment after removal of silicone oil occurred in 17.0% of the cases. Recurrence of retinal detachment under silicone oil occurred in 45.1% of the cases; the cause of the recurrence was PVR in 97.6% of those patients. No serious complication of silicone oil tamponade occurred. The mean duration of the tamponade was 6.7 months. The best results were achieved among patients showing no recurrence with silicone oil: visual acuity above 4/200 in 84.6% of the patients, above 20/200 in 61.5% of the patients and above 80/200 in 20.5% of the patients. In case of recurrence with silicone oil treatment, visual acuity reached 4/200 in 70.4% of the patients and was above 20/200 in 25.9% of the patients. DISCUSSION AND CONCLUSION: The results of this study are equivalent to those of studies in which analysis was made after removal of silicone oil. Proliferative vitreoretinopathy remains the only risk factor of retinal detachment recurrence with silicone oil (p<0.01). The number of previous surgeries is not a risk factor for postoperative PVR. Retinectomy is a surgical procedure that seems to improve the results in cases of severe PVR.

Simple retinal detachments: identifying the at-risk case.

The success rate of retinal reattachment surgery has now reached over 90%. The major cause of failure is attributable to the development of proliferative vitreoretinopathy (PVR). It is a complex process comprised of events that are similar to those of the wound healing response with inflammation, migration and proliferation of a variety of cells. These membranes can exert traction and reopen previously closed retinal breaks, create new breaks, and distort or obscure the macula. In the early part of this century the success rate of retinal reattachment surgery was virtually nil and it was not until a better understanding of the pathophysiology of retinal detachment was gained that the success rate improved. It was Gonin who emphasised the relationship between vitreous detachment and traction resulting in retinal tears that led to treatment aimed at closing retinal breaks. To increase even further the final success rate in the treatment of 'simple retinal detachments' a better understanding of the risk factors for PVR is needed in patients presenting with acute retinal detachments. Such risk factors can be broadly divided under the headings of preoperative risk factors, best surgical management and possibly adjuvant therapy.

Shifting subretinal fluid in rhegmatogenous retinal detachment.

In a consecutive series of 470 cases of rhegmatogenous retinal detachment 25 (5%) were found to have shifting subretinal fluid (SRF) at the preoperative examination. The study showed that the association between SRF and rhegmatogenous retinal detachment is unusual but not rare. Shifting SRF was most often associated with aphakic and longstanding retinal detachment, and found in cases in which the retinal holes were small.

Severe proliferative vitreoretinopathy and retinal detachment. I. Initial clinical findings.

We studied 716 eyes of 697 patients with retinal detachment associated with the more advanced stages of proliferative vitreoretinopathy (PVR). The factors that influenced the severity of PVR and our criteria for surgical treatment were analyzed using statistical methods. The more severe cases of PVR showed a higher prevalence of cases with (1) retinal detachment exceeding 12 months' duration, (2) no retinal breaks observed, (3) the largest retinal break of a size equal to or exceeding one clock hour, and (4) poor initial visual acuity. Compared with the unoperated group, the eyes on which we subsequently operated were characterized by a greater prevalence of (1) patients with bilateral retinal detachment complicated by PVR, (2) cases with relatively recent onset of retinal detachment, (3) phakic eyes, (4) eyes without vitreous hemorrhage, (5) eyes with one or more visible retinal breaks and with smaller breaks, (6) relatively better initial visual acuity, and (7) less severe degrees of PVR.

The use of colour Doppler imaging in the diagnosis of retinal detachment.

DESIGN: Prospective study. PURPOSE: To evaluate real-time duplex colour Doppler examination with colour and pulse Doppler ultrasonography (US) (colour Doppler imaging (CDI)) for detection of the retinal detachment from membranous structures in the posterior segment. MATERIALS AND METHODS: In 33 consecutive patients with ophthalmoscopically invisible eyes (34 eyes), CDI was performed to detect the presence or absence of retinal detachment. The diagnostic criterion for retinal detachment was whether or not spectral waveforms were detected in membranous structures with colour and pulse Doppler US. In all cases, the absence or presence of retinal detachment was confirmed by surgery. RESULTS: In 27 of 34 eyes, membranes and/or opacities were observed in the vitreous cavity with CDI. In 12 of these 27 eyes, blood flow in those structures was detected by CDI. In all of these 12 eyes, retinal detachment was confirmed at surgery, and in 14 of the 15 eyes in which blood flow was not detected by CDI, absence of retinal detachment was confirmed at surgery. When a diagnosis confirmed by surgery was used as the definitive finding, CDI had a sensitivity of 92.3%, specificity of 100%, positive predictive value of 100%, negative predictive value of 93.3%, and an accuracy in the detection of retinal detachment from membranes and/or opacities in the vitreous cavity of 96.3%. CONCLUSION: Real-time duplex colour Doppler examination with colour and pulse Doppler US (CDI) is a noninvasive method useful for the detection of retinal detachment from vitreous opacity and/or membrane in the posterior segment.

[Late recurrent retinal detachment after scleral buckling].

PURPOSE: To analyze the physiopathologic mechanism, therapeutic modalities, and prognosis of late recurrent retinal detachment. METHODS: A retrospective study was conducted on late recurrent retinal detachment operated with episcleral surgery over a 15-year period. Ten patients were included in this study. RESULTS: Late recurrent retinal detachments occurred in 0.39% of all retinal detachments repaired by episcleral surgery over 15 years. Redetachment occurred 3-7 years after surgery, with etiologies including new retinal breaks (seven cases), reopening of old breaks (three cases), and removal of scleral explant (one case). Proliferative vitreoretinopathy (PVR) grade B was seen in three cases, grade C in six cases, and grade D in one case. After reoperation, the retina was reattached in nine cases. Three eyes were treated with scleral buckle, the others underwent vitreoretinal surgery. Failure occurred in one patient who had a very high level of vitreoretinal proliferation. CONCLUSION: Late recurrent retinal detachments are rare and vitreous base traction seems to be an important factor, although the associated PVR was probably a secondary factor. Treatment depends on PVR, with vitreoretinal surgery necessary in some cases. They usually have a good prognosis.

[Surgical treatment of non-traumatic retinal detachment in children under 15 years of age].

Etiological and clinical features of 151 retinal detachments in childhood are studied and discussed. Results of surgical management of 92 of them, after at least a 6 month follow-up, especially after ablation of silicon oil when used temporarily, are described. Clinical aspects of the contralateral eyes and their prophylactic treatment is also studied. Though surgical techniques have done great strides, prognosis of retinal detachment in childhood is still desperately poor. Proliferative vitreo-retinopathy, frequent, early and very progressive, is the leading complication and cause of failure in surgical of these retinal detachment. In this series of 151 retinal detachments, only 38% have achieved long term retinal reattachment because of it. If high grade (C-D) proliferative vitreo-retinopathy is associated 14.5% only achieved long term reattachment though 86% it when proliferative vitreo-retinopathy was moderate or absent. It is for this reason that we wish to emphasize the need to inform practitioners and "at risk" families. Strict and systematic follow-up of the "at risk eye" is essential. The most complete surgery at the outset seems to be the best way of managing high-grade proliferative vitreo-retinopathy associated with retinal detachments.

[A case of nonrhegmatogenous retinal detachment in Dandy-Walker Syndrome].

A 2-month-old female presented with nonrhegmatogenous retinal detachment in Dandy-Walker syndrome. At the fist examination, coloboma involving the optic disc in both eyes was detected. The left eye showed microphthalmos with sclerocornea, persistent pupillary membrane, hypoplasia of the iris stroma, and bullous retinal detachment near the optic disc. Chromosomal analysis revealed a mosaic pattern: 46, XX/47, XXX. Increased intracranial pressure associated with Dandy-Walker syndrome was detected by a neurosurgeon at the age of 3 months. The patient was followed for several weeks, and then nonrhegmatogenous retinal detachment appeared in the right eye. Subretinal fluid alternately increased and decreased in both eyes. A ventriculo-peritoneal shunt was performed at the age of 6 months, and the retinal detachment was remarkably reduced in both eyes after lowering of intracranial pressure. Coloboma involving the optic disc, sclerocornea, persistent pupillary membrane, hypoplasia of iris stroma, and Dandy-Walker syndrome were thought to be caused by the abnormal development of neural crest cells. We surmised that the retinal detachment in this case might have resulted from a communicating pathway between the subarachnoid space and the subretinal space. We concluded that the etiology of retinal detachment associated with optic disc anomaly should be investigated to determine adequate treatment.

Spontaneous reattachment of rhegmatogenous retinal detachment.

PURPOSE: To describe the clinical characteristics of spontaneous reattachment of rhegmatogenous retinal detachment (SRRRD). DESIGN: Retrospective observational case series. PARTICIPANTS: Fifteen patients who were diagnosed with SRRRD. METHODS: The medical records of 15 patients were reviewed. Spontaneous reattachment of rhegmatogenous retinal detachment was confirmed via serial observation in 4 of the eyes, and the remaining eyes represented patients in whom the condition was presumed to develop. MAIN OUTCOME MEASURES: Clinical features and association. RESULTS: This study involved 6 male patients and 9 female patients with a mean age of 48.0 years. The mean refractive errors in the involved and contralateral eyes were -5.0 and -5.3 diopters, respectively. All 15 eyes evidenced diffuse retinal pigmentary alterations within a sharply demarcated and convex margin. The lesions were located in the inferior retina in 10 of the 15 eyes, limited to 6 clock hours or fewer (66.7%). Although subretinal gliotic bands were detected within the lesion in 11 patients (73.3%), epiretinal proliferation was evident in only 2 patients (13.3%). Retinal changes associated with rhegmatogenous retinal detachment were noted in the fellow eyes of 7 patients (46.7%). CONCLUSIONS: Spontaneous reattachment of rhegmatogenous retinal detachment should be included in differential diagnoses of patients with diffuse retinal pigmentary alterations within a sharply demarcated convex margin in unilateral eyes. Small retinal breaks observed in nonvitrectomized eyes may be associated with the occurrence of SRRRD.
