Surgical repair of large cyclodialysis clefts.

PURPOSE: To describe a new surgical technique to effectively close large (>180 degrees) cyclodialysis clefts. METHODS: Our method involves the use of procedures commonly associated with repair of retinal detachment and complex cataract extraction: phacoemulsification with placement of a capsular tension ring followed by pars plana vitrectomy and gas tamponade with light cryotherapy. We also used anterior segment optical coherence tomography (OCT) as a noninvasive mechanism to determine the extent of the clefts and compared those results with ultrasound biomicroscopy (UBM) and gonioscopy. RESULTS: This technique was used to repair large cyclodialysis clefts in 4 eyes. All 4 eyes had resolution of hypotony and improvement of visual acuity. One patient had an intraocular pressure spike requiring further surgical intervention. Anterior segment OCT imaging in all 4 patients showed a more extensive cleft than UBM or gonioscopy. CONCLUSIONS: This technique is effective in repairing large cyclodialysis clefts. Anterior segment OCT more accurately predicted the extent of each cleft, while UBM and gonioscopy both underestimated the size of the cleft.

Risk factors associated with retinal hemorrhage in suspected abusive head trauma.

PURPOSE: To determine risk factors associated with retinal hemorrhage (RH) in pediatric abusive head trauma (AHT) suspects. METHODS: Records of children aged 0-3 years hospitalized for suspected AHT from January 2007 to November 2011 were retrospectively reviewed in this case-control study. Children were classified into case and control groups based on RH presence. Medical history, presenting symptoms, reasons, and characteristics of injury were recorded. Logistic regression analysis was performed to identify risk factors. RESULTS: A total of 168 children (104 males) were included. Of these, 103 were classified as cases and 65 as controls. The mean age (with standard deviation) was 9.3 ± 8.3 months (range, 1 day-36 months). Of the 103 cases, 22 (21%) had subretinal hemorrhage, 9 (9%) had retinoschisis, and 1 (1%) had vitreous hemorrhage. Children presenting with lethargy or altered mental status (P < 0.0001), subdural hemorrhage (P < 0.0001), and other radiologic findings (eg, cerebral ischemia, diffuse axonal injury, hydrocephalus, or solid organ injury; P = 0.01546) were likely to have RH. All 23 children with skull or nonskull fracture without intracranial hemorrhage did not have RH (P < 0.0001 both categories). CONCLUSIONS: Retinal hemorrhages were almost never found in the absence of intracranial hemorrhage and not found in the setting of fracture without intracranial hemorrhage.

A comparison of two-way text versus conventional paging systems in an academic ophthalmology department.

Alphanumeric paging systems are unidirectional without prioritization capabilities. Newer electronic communication devices such as two-way text paging systems are capable of bidirectional paging and prioritization. While previous studies have evaluated alphanumeric paging systems in academic hospital settings, bidirectional two-way text paging systems have not been investigated. The goal of this study was to evaluate efficiency and impact on patient care delivery of a two-way text paging system compared to conventional one-way alphanumeric pagers. This unmasked, crossover prospective study was divided into three phases. In phase one, surveys were distributed to all ophthalmology attending physicians, residents, clinical technicians, and secretaries to assess the conventional alphanumeric paging system. In phase two, these participants used two-way text pagers without instruction (unstructured format) that they subsequently compared to the alphanumeric system with devised surveys assessing (on a scale of 0 to 100) time saved, increased daily efficiency, facilitation in patient care, and overall impression (helpfulness).In phase three, participants used a specific communication prioritization protocol (structured format) with the two-way text pagers with subsequent comparison and assessment with the same surveys. Compared to traditional alphanumeric pagers, new digital two-way text pagers were found to be statistically (p < 0.0001) more helpful by participants in all categories: as a time saver (80.33 vs. 56.95) p < 0.0001, increased daily efficiency (78.15 vs. 57.13) p < 0.0001, facilitation in patient care (78.79 vs. 56.95) p < 0.0001, and overall impression (helpfulness) (61.82 vs. 84.33) p < 0.0001. When compared to the alphanumeric pager, the two-way text pager was found to decrease subjectively call backs (73.6% to 45.6%, p < 0.0001), reduce interruptions of learning activities (43.63% to 26.6%, p < 0.0001) and enabled better patient care (59.8% to 42.2%, p < 0.0001). No significant statistical difference was found between the structured and unstructured system. Two-way text paging (structured versus unstructured guidance) was preferred over the conventional one-way alphanumeric paging system in every participant category. Two-way text paging is an effective alternative to alphanumeric paging, demonstrating saved time, increased daily efficiency, reduced call backs and interruptions of educational activities, and facilitation in patient care.

Symptomatic posterior vitreous detachment and the incidence of delayed retinal breaks: case series and meta-analysis.

PURPOSE: To establish the necessity for an early follow-up examination after an initial funduscopic examination with negative results for patients with acute, symptomatic posterior vitreous detachment (PVD). DESIGN: Retrospective case-control study and meta-analysis. METHODS: Records were reviewed of patients seeking treatment over a 4.5-year period who were diagnosed with an acute, symptomatic PVD. A MEDLINE search to identify all published observational case studies reporting vitreoretinal pathologic features after acute, symptomatic PVD. RESULTS: The incidence of retinal tears in eyes with a symptomatic PVD was 8.2%. The overall rate of retinal break in the meta-analysis portion of the study was 21.7%. In total, 1.8% of patients had retinal tears that were not seen on initial examination. Of the 29 patients with delayed-onset retinal breaks, 24 (82.8%) had at least one of the following: vitreous hemorrhage at initial examination, hemorrhage in the peripheral retina at initial examination, or new symptoms. CONCLUSIONS: If the results of an initial examination of a patient with an acute, symptomatic PVD are negative for retinal tears, the necessity of early follow-up may be best determined by the presence of pigmented cells in the vitreous, vitreous hemorrhage, or retinal hemorrhage. Most patients with symptomatic PVD may not need an early follow-up examination.

Lens clarity after 3-port lens-sparing vitrectomy in stage 4A and 4B retinal detachments secondary to retinopathy of prematurity.

OBJECTIVE: To assess lens clarity after 3-port lens-sparing vitrectomy for stages 4A and 4B tractional retinal detachment secondary to retinopathy of prematurity. METHODS: In a retrospective, interventional, consecutive clinical case series, 108 eyes of 102 patients who underwent lens-sparing vitrectomy for stages 4A and 4B tractional retinal detachment from February 1, 1998, through January 31, 2004, were reviewed. All procedures and follow-up examinations were performed by a single surgeon. Lens clarity was assessed at the final follow-up examination. RESULTS: Of the 108 eyes reviewed, 102 (94.4%) maintained clear lenses at the final follow-up examination, which ranged from 6 to 48 months (mean, 32 months) after the procedure. Thirty-two eyes had stage 4A detachments and 76 eyes had stage 4B. CONCLUSIONS: Three-port lens-sparing vitrectomy may be performed with relatively low risk of cataract formation during the early postoperative period. Maintenance of a clear crystalline lens during the critical period of visual development may lead to better functional outcomes.
