Treatment choice and quality of life in patients with choroidal melanoma.

OBJECTIVE: To determine if quality of life differs between patients with choroidal melanoma treated with enucleation and those treated with radiation therapy. MATERIALS AND METHODS: Patients treated for choroidal melanoma at 5 Midwest centers were asked to participate. There were 65 participants treated with enucleation and 82 treated with radiation therapy. Quality of life was assessed using the Medical Outcome Study Short Form 36 and the National Eye Institute Visual Function Questionnaire and by the Time-Tradeoff interview method. RESULTS: The average length of follow-up was 4.9 years for the group treated with radiation therapy and 6.3 years for the group treated with enucleation (P = .05). After adjusting for age, sex, years of follow-up, and the number of chronic conditions, there were few differences in any of the quality-of-life measures by treatment status. Participants in the group treated with radiation therapy were more likely to have higher (better) scores on the Vitality and Mental Component subscales of the Medical Outcome Study Short Form 36 than participants treated with enucleation. There were no differences on the National Eye Institute Visual Function Questionnaire or the Time-Tradeoff measures of quality of life. CONCLUSION: Choice of treatment for choroidal melanoma does not seem to be associated with large differences in quality of life in long-term follow-up.

Pneumatic buckle for the repair of primary rhegmatogenous retinal detachment.

OBJECTIVES: This prospective study examines the effectiveness of the pneumatic buckle procedure (nondrainage scleral buckle with pneumatic retinopexy) for repair of primary rhegmatogenous retinal detachments. METHODS: We studied 58 consecutive patients with primary rhegmatogenous retinal detachments who underwent a pneumatic buckle with air or SF6. The procedures were performed at 2 centers. Retinal reattachment and visual acuity were examined. RESULTS: The single operation reattachment rate for patients undergoing a pneumatic buckle procedure was 95%. Eighty eight percent of patients with macula-on detachment had unchanged or improved final visual acuity. Sixty seven percent of patients with macula-off detachments had a final visual acuity between 20/20 and 20/50. Twenty nine percent had final visual acuity between 20/60 and 20/200. Two patients developed a new retinal hole postoperatively. CONCLUSION: Pneumatic buckle is an effective technique for repair of primary rhegmatogenous retinal detachments caused by breaks in the superior 8 o'clock segment. This technique avoids the complications associated with the drainage portion of the traditional scleral buckle operation and results in a high rate of retinal reattachment and stable or improved visual acuity. The rate of new retinal hole formation in this study is much lower than those reported for pneumatic retinopexy.

Nonarteritic anterior ischemic optic neuropathy with macular edema: visual improvement and fluorescein angiographic characteristics.

The objective of the study was to assess visual outcomes in patients who have nonarteritic anterior ischemic optic neuropathy (NAION) with macular edema (ME). Thirteen eyes (12 patients) with NAION and ME were observed for an average of 5.3 months after onset of visual loss. Intravenous fluorescein angiography was performed on 10 eyes. Fluorescein leakage was observed in 8 of 10 (80%) eyes. Leakage was nonfocal, minimal, and diffuse. Eleven of 13 (85%) eyes with ME improved. The average improvement was 2.3 Snellen lines. The presence of ME in patients with NAION may confer a better visual prognosis than reported in patients with NAION alone.

Vitrectomy in patients with decreased visual acuity secondary to asteroid hyalosis.

PURPOSE: To evaluate the role of vitrectomy in patients with decreased visual acuity solely attributable to asteroid hyalosis. METHOD: We retrospectively reviewed the records of patients with asteroid hyalosis and identified those who underwent vitrectomy for symptomatic asteroid hyalosis alone. RESULTS: After vitrectomy, nine of 10 eyes (10 patients) had at least 1 line of improvement in nonstandardized best-corrected visual acuity. In one eye, vision was unchanged postoperatively. The average gain was 3.44 lines. CONCLUSIONS: A small percentage of patients with asteroid hyalosis have decreased visual acuity caused solely or primarily by the asteroid hyalosis. Vitrectomy in these patients may alleviate symptoms and improve visual acuity.

Bacterial contamination of anaerobic vitreous cultures: using techniques employed for endophthalmitis.

PURPOSE: To investigate the occurrence of contaminated cultures of vitreous specimens from non-infected eyes obtained using anaerobic techniques employed for endophthalmitis. METHODS: Vitreous specimens were obtained using meticulous sterile techniques employed for endophthalmitis from seventeen patients undergoing pars plana vitrectomy for non-infective indications: vitreous hemorrhage (12 eyes), retinal detachment (3), Coat's disease (1), and congenital dislocated lens(1). Vitreous specimens were inoculated in the operating room onto an anaerobic blood agar plate and into thioglycolate broth. Bacterial growth occurring before 10 days was considered positive. RESULTS: Three organisms were isolated from three separate eyes. One colony of Staphylococcus species was isolated on an anaerobic blood agar plate on day 3. A single colony of Propionibacterium acnes grew on an anaerobic blood agar plate on day 6. Alpha-hemolytic streptococci grew from thioglycolate broth on day 10. CONCLUSIONS: Growth as detected in this study might represent contaminating rather than an infecting organism in an eye suspected of having endophthalmitis.

Combined extracapsular cataract extraction, posterior chamber intraocular lens implantation, and pars plana vitrectomy.

The surgical management of coexisting cataract and vitreoretinal disease has been controversial, particularly for eyes with a history of proliferative diabetic retinopathy (PDR) or chronic uveitis. We retrospectively studied the results of combined extracapsular cataract extraction (ECCE), posterior chamber intraocular lens (PC-IOL) implantation, and pars plana vitrectomy in 20 eyes of 16 patients. The indications for combined vitrectomy included dense, nonclearing vitreous hemorrhage attributed to PDR in 10 eyes, age-related macular degeneration in 2, and trauma in 1. The remaining 7 eyes had pars plana vitrectomy to remove inflammatory vitreous cell and debris associated with chronic uveitis. Follow up ranged from 4 to 32 months (average, 17.4 months). Visual acuity improved in 19 eyes (95%)--to 20/100 or better in 12 (60%). The improvement ranged from 1 to 13 Snellen lines (average, 4.9 lines). Postoperative visual acuity improvement averaged 7.5 Snellen lines for eyes with chronic uveitis, 7.0 lines for those with age-related macular degeneration, and 3.3 lines for those with a history of PDR. Postoperative visual acuity was less than 20/100 in 8 eyes (40%). In most cases, these latter results were attributed to macular changes associated with the underlying ocular disease. Our results confirm previous studies that have shown that combined ECCE/PC-IOL implantation and pars plana vitrectomy is a well-tolerated surgical procedure for diabetics, which can provide clear anterior and posterior segment media. In addition, our results suggest that this combined procedure can be useful in restoring vision in certain eyes with uveitis in the short-term postoperative period.

Extracapsular cataract extraction and posterior chamber intraocular lens implantation in uveitis patients.

PURPOSE: Intraocular lens implantation in uveitis patients has been a controversial issue. The purpose of this study is to evaluate the visual and surgical outcomes of extracapsular cataract extraction (ECCE) and posterior chamber intraocular lens (PC IOL) implantation in a diverse group of uveitis patients. PATIENTS AND METHODS: The results of 39 cases of ECCE and PC IOL implantation in 30 patients with uveitis were retrospectively analyzed. Five patients (six eyes) had pars plana vitrectomies combined with ECCE and PC IOL implantation. Patient age ranged from 26 to 71 years (average, 53.0 years). Specific uveitic syndromes were determined for 22 patients (73.3%). The postoperative follow-up period ranged from 6 to 43 months (average, 20.3 months). RESULTS: Visual acuity improved postoperatively in 38 eyes (97.4%), and this improvement ranged from 1 to 11 Snellen lines (average, 7.5 Snellen lines). Visual acuity improved postoperatively to 20/40 or better in 32 eyes (82%). Seven eyes had visual acuity worse than 20/40, which was attributed to posterior segment abnormalities after ECCE and PC IOL implantation. Uveitis recurred in 20 eyes (51.3%), and postoperative cystoid macular edema (CME) was observed in 18 eyes (46.2%). In all cases, the recurrent uveitis and CME improved or resolved with corticosteroid therapy. CONCLUSION: These results suggest selected uveitis patients can have improved vision without unacceptable risk for 1 to 3 years after ECCE and PC IOL implantation.

Retinal pigment epithelium lesions as a biomarker of disease in patients with familial adenomatous polyposis. A follow-up report.

BACKGROUND: The sensitivity of retinal pigment epithelium (RPE) lesions as a predictive congenital marker for the development of familial adenomatous polyposis (FAP) is evaluated. METHODS: In a prospective study, 34 patients at 50% risk of inheriting FAP were examined. Based on the presence or absence of four or more RPE lesions, patients were categorized as those who had inherited or those who lacked the FAP genes. All patients received dilated fundus examinations with binocular indirect ophthalmoscopy and all RPE lesions were documented with fundus photography. All patients underwent annual sigmoidoscopy to determine the presence or absence of polyps. RESULTS: A 3-year follow-up analysis showed that 8 of 14 patients who were positive for RPE lesions later developed polyps. Of the 20 patients considered negative for FAP based on normal fundus examination, none has developed polyps. CONCLUSION: The authors urge all patient at risk of inheriting FAP to undergo dilated fundus examination with binocular indirect ophthalmoscopy and wide-angle fundus photography at the earliest age possible. All patients with 4 or more RPE lesions should undergo annual sigmoidoscopic examinations beginning before 10 years of age.

Predictive value of congenital hypertrophy of the retinal pigment epithelium as a clinical marker for familial adenomatous polyposis.

One hundred forty-eight members of 53 kindreds with familial adenomatous polyposis (FAP) were examined for congenital hypertrophy of the retinal pigment epithelium (CHRPE) and extracolonic manifestations (ECM) to assess the value of CHRPE as a predictive marker for FAP. Based on eye examination results, the families were divided into 2 groups. In a first group of 34 families, all 61 members diagnosed as having polyps and 13 of the 33 patients at risk had 4 or more lesions distributed in both eyes. By contrast, in a second group of 18 families, all 32 polyposis patients and all 18 members at risk had less than 4 lesions. Extra-colonic manifestations were present in 26 of 34 families in the first group and in 11 of 18 families in the second group. Data on one family with ambiguous ancestry were reviewed separately. The existence of 4 or more CHRPE lesions distributed in both eyes seems to be a congenital marker for FAP, present in 65.4 percent of families. When present in a family: 1) it is found in all diagnosed patients in that family, 2) can therefore be considered predictive for the development of polyps in other family members who carry the trait, and 3) if confirmed by longer follow-up, may possibly preclude members without the trait from further evaluation and surveillance.

Managing diabetic retinopathy.

Diabetic retinopathy is a leading cause of visual impairment and blindness. The disease is more likely in patients with insulin-dependent diabetes mellitus, and the incidence is higher in diabetes of long duration. In background diabetic retinopathy, the vascular changes are confined to the retina; in proliferative retinopathy, vessels grow onto the posterior vitreous surface or wedge between the retina and the vitreous. Diagnostic accuracy is more likely with an ophthalmologic consultation. A team approach between the ophthalmologist and the primary care physician is recommended for effective overall management of these patients.

Hibiclens keratopathy. A clinicopathologic case report.

A 39-year-old woman developed a painful, red eye immediately following oral surgery associated with preoperative preparation of her face with the antiseptic, Hibiclens. Epithelial and stromal edema was observed 2 weeks after surgery and progressed to diffuse bullous keratopathy. This led to penetrating keratoplasty 10 months later. Light and electron microscopic findings of the cornea included epithelial edema with bullous changes, marked loss of keratocytes, a thickened Descemet's membrane, and an attenuated, disrupted endothelial cell layer. These findings demonstrate the corneal damage that may occur following ocular exposure to Hibiclens.

An update on multiple recurrent serosanguineous retinal pigment epithelial detachments in black women.

A unique clinical entity of multiple recurrent serosanguineous retinal pigment epithelial detachments in three black women was first described by the authors in 1985. Nine patients with this entity have now been observed, all of whom have developed a vitreous hemorrhage in at least one eye. Vitreous hemorrhage was the initial clinical presentation in seven eyes and developed 63.5 months after initial presentation in another patient who eventually sustained bilateral vitreous hemorrhages. Ultrasonographic examination in this entity often shows a characteristic pattern of irregular choroidal thickening and retinal elevation, which may aid in the diagnosis when the presentation is that of a vitreous hemorrhage of unknown origin. Vitrectomy has been performed in three cases, two of these retaining clear media during subsequent follow-up. Postvitrectomy vision correlated with the extent of macular involvement by the underlying disease. Eight patients had a history of, or evidence of, hypertension. Although choroidal neovascular membranes are a potential cause, the definitive etiology is not known.

Congenital hypertrophy of the retinal pigment epithelium in familial adenomatous polyposis.

One hundred fifty-three members of 56 kindreds with familial adenomatous polyposis (FAP) underwent funduscopic examination for congenital hypertrophy of the retinal pigment epithelium (CHRPE). All patients underwent wide-angle fundus photography to document lesions, proctosigmoidoscopy to document polyps, and examination for extracolonic manifestations. Ninety-seven patients were diagnosed as having FAP and 56 patients were offspring of FAP patients and thus at 50% risk of inheriting the disease. In two thirds of the kindreds, CHRPE could be used as a congenital phenotypic marker to predict the presence or development of polyps. In these kindreds, all patients with diagnosed FAP and 39% of the patients at risk had at least four CHRPE lesions. In one third of the kindreds, CHRPE could not be used as a predictive congenital marker, and in these kindreds all patients had zero to three total lesions of CHRPE. The presence of CHRPE did not correlate with any other extracolonic manifestations. In kindreds without any other extracolonic manifestations, CHRPE can still be present and can be used as a predictive congenital phenotypic marker.

Complications after proton beam therapy for uveal malignant melanoma. A clinical and histopathologic study of five cases.

Proton beam therapy for uveal malignant melanoma has been advocated as effective therapy because of documented reduction in tumor size and few clinical complications. However, some eyes have been removed because of adverse effects. The authors report the clinical courses and pathologic findings of five eyes enucleated after proton beam irradiation. Neovascular glaucoma had developed in three eyes, two eyes had vitreous hemorrhage, and two had extraocular extension. The tumors in the radiation treatment field showed continued postirradiation growth clinically in four of the five eyes, and mitotic activity histologically in all five cases. Two and one half years after irradiation, and nearly 2 years after subsequent enucleation, one of those two patients had biopsy-proven liver metastases, and later died. Despite the considerable success rate of proton beam irradiation, the potential for clinical complications and subsequent tumor growth remains.

Comparison of pneumatic retinopexy with alternative surgical techniques.

To determine the efficacy of pneumatic retinopexy, the authors conducted a retrospective study of 56 cases of uncomplicated retinal detachments (RDs) treated with this technique (follow-up, 6-18 months). These were compared with 28 similar cases treated with a Lincoff balloon and 78 similar cases treated with a scleral buckle. The long-term success rates for these three groups were 71, 64, and 96%, with the incidence of new breaks being 20, 18, and 1.3% respectively. In aphakic or pseudophakic patients with an absent or ruptured posterior capsule, the success rate for pneumatic retinopexy was only 43%. In phakic and aphakic patients with an intact posterior capsule, the success rate for pneumatic retinopexy improved to 81%. These data suggest that this technique is less effective in aphakic or pseudophakic patients with an absent or ruptured posterior capsule and that careful follow-up to detect new breaks is necessary in all cases. A prospective randomized study is needed to verify these data.

Chronic Propionibacterium endophthalmitis after extracapsular cataract extraction and intraocular lens implantation.

We studied six cases of chronic, indolent intraocular inflammation that occurred after extracapsular cataract extraction and posterior chamber intraocular lens implantation. The inflammation was characterized by a delayed onset, and in three cases had the clinical appearance of a granulomatous iridocyclitis. Cultures of intraocular specimens obtained from six eyes yielded Propionibacterium; five yielded P. acnes. Pleomorphic gram-positive bacilli consistent with Propionibacterium were identified in cytologic or histopathologic studies in four of the six culture-positive cases. After surgical and medical therapy, the inflammation resolved. Postoperative Propionibacterium endophthalmitis may masquerade as a chronic iridocyclitis.
