Recurrence rate of pleomorphic adenoma of the lacrimal gland: systematic review and meta-analysis.

PURPOSE: The aim is to increase the understanding of lacrimal gland pleomorphic adenoma's recurrence rate and the factors that influence it. METHODS: A systematic search of PubMed, SCOPUS, Cochrane Library, and CINAHL was conducted following PRISMA guidelines. The data in the included studies were extracted and analyzed. RESULTS: Twenty-two studies were included representing 963 patients from 12 different countries. The pooled analysis of the recurrence rate was 8.83% (95% CI: 5.08-13.50). In the event of recurrence, there was a 75.17% (95% CI: 65.98-82.94) chance of benign recurrence and a 28.35% (95% CI: 19.66-38.41) chance of malignant recurrences, with malignant recurrence occurring almost exclusively after a benign recurrence. The results showed that 47.09% (95% CI: 24.60 to 70.22) of recurrent tumors had a ruptured pseudocapsule and 6.35% (95% CI: 0.82 to 16.54) had an intact pseudocapsule with a significant difference between the two. Of the recurrent tumors, 51.50% (95% CI: 9.28 to 92.39) were biopsied compared to 8.83% (95% CI: 3.40 to 16.49) of the total; the difference between these two proportions was also found to be significant. CONCLUSION: There was a statistically significant difference in the rates of recurrence between tumors that were either biopsied or had a ruptured pseudocapsule compared to those that did not. This evidence adds additional support for excisional biopsy being the procedure of choice for LGPA and reinforces the importance of keeping the pseudocapsule intact during surgical resection.

Revision dacryocystorhinostomy: systematic review and meta-analysis.

PURPOSE: The goal of this study is to determine if a certain revision DCR approach (external, endoscopic endonasal, laser transcanalicular) is superior to others. Additionally, this investigation evaluates the effect of the primary surgery on success of revision. METHODS: This investigation is a systematic review and meta-analysis. All studies specifying type of primary DCR and revision DCR were included. Proportion of successes of each revision for every primary surgery was obtained from the included studies. Meta-analyses were performed to determine cumulative proportions of successes across studies. OUTCOME MEASURES: Significant differences in the proportions yielded by meta-analysis of successes among different surgical approaches. RESULTS: The type of primary surgery did not significantly influence overall revision success if the same procedure was used for the revision. Overall successes per each revision type were not significantly different. When performing subgroup analyses per each primary surgery, all methods of revisions were similar in efficacy with one exception: when the primary surgery was done using the laser transcanalicular approach, external revision outperformed repetition of the primary method. CONCLUSIONS: Regarding success of re-operation, surgeons can use the method they are most comfortable with to perform DCR revisions. However, primary transcanalicular laser DCRs should be revised, if necessary, using the external approach.

Orbital Fractures and Associated Ocular Injuries in Operation Iraqi Freedom and Operation Enduring Freedom Referred to a Tertiary Care Military Hospital and the Effect on Final Visual Acuity.

PURPOSE: To update the incidence of orbital fractures in U.S. Soldiers admitted to the former Walter Reed Army Medical Center from 2001 to 2011 after sustaining combat injuries in Operation Iraqi Freedom and Operation Enduring Freedom. METHODS: Data were collected in the Walter Reed Ocular Trauma Database. Inclusion criteria were any U.S. Soldier or Department of Defense civilian with an orbital fracture injured in Operation Iraqi Freedom/Operation Enduring Freedom. Primary outcome measures were final visual acuity and the effect of orbital fracture, number of fractures, and anatomic location of fracture on final visual acuity. RESULTS: Eight-hundred ninety eye injuries occurred in 652 patients evacuated to Walter Reed Army Medical Center between 2001 and 2011. Orbital fractures occurred in 304 eyes (34.2%). A single wall was fractured in 140 eyes (46.05%), 2 in 99 (32.6%) eyes, 3 in 31 (10.2%), 4 in 28 (9.2%), and unknown in 6 (1.9%) eyes. Roof fractures were found in 74 (24.34%), medial wall in 135 (44.41%), lateral wall in 109 (35.9%), and floor fractures in 217 (71.4%). Final visual acuity was analyzed and 140 (46.05%) eyes had greater than 20/40 vision, 17 (5.59%) were 20/50 to 20/200, 26 (8.5%) were count fingers to light perception, and 95 (31.3%) were no light perception. In logistic regression analysis, roof (p = 0.001), medial (p = 0.009), and lateral fractures (p = 0.016) were significantly associated with final visual acuity less than 20/200, while floor fractures were not (p = 0.874). Orbital fracture and all fracture subtypes were significantly associated with traumatic brain injury, retrobulbar hematoma, optic nerve injury, but not for vitreous hemorrhage, commotio, hyphema, and choroidal rupture. Fracture repair was noted in 45 (14.8%). CONCLUSIONS: Orbital fractures occurred in a third of Operation Iraqi Freedom/Operation Enduring Freedom eyes of ocular trauma patients referred to one tertiary care military hospital. This resulted in approximately 40% of these eyes remaining legally blind after injury.Orbital fractures occur commonly during combat trauma and a significant number are legally blind despite appropriate treatment.

Esophageal adenocarcinoma and urothelial carcinoma orbital metastases masquerading as infection.

Orbital metastases can masquerade as other orbital processes. We present two cases of orbital metastases, the first being the first reported adenocarcinoma of the esophagus presenting as an orbital metastasis prior to the primary being known, and the other as the first urothelial carcinoma to present as orbital cellulitis. The first patient presented with left upper eyelid pain. CT scan identified a superolateral subperiosteal fluid collection without concomitant sinus disease, which was drained in the operating room. Two weeks later repeat CT scan showed recurrent orbital subperiosteal fluid. It was drained and a biopsy showed necrotic adenocarcinoma. The second case presented with a painless right proptosis, decreased vision, and globally decreased ocular motility 3 days after bladder resection for urothelial carcinoma. CT scan demonstrated pan sinusitis with a soft tissue mass in the apex of the right orbit with extension through the superior orbital fissure. After no improvement on antibiotics endoscopic drainage was performed. Pathology revealed metastatic urothelial carcinoma within the orbital fat.

Growth of a presumed orbital venous anomaly during pregnancy with spontaneous resolution postpartum.

A 27-year-old pregnant woman in her second trimester presented with a 3-month history of gradual proptosis, decreased vision, and choroidal folds in her right eye. MRI revealed an intraconal mass with inhomogeneous enhancement consistent with a vascular lesion. The patient was followed clinically and the lesion remained stable for the remainder of her pregnancy and delivery by Cesarean section. Three months postpartum, the proptosis, choroidal folds, and decreased vision had resolved. Repeat scanning revealed complete resolution of the lesion. Pregnant patients with orbital vascular lesions need to be followed carefully during their pregnancy and after delivery. These lesions can worsen during pregnancy and may resolve spontaneously in the postpartum period.

"Feasibility and utility of a simple computerized test for measuring saccade latency in progressive supranuclear palsy- a proof-of-concept study".

BACKGROUND: Reliable detection of slowed vertical saccades may help discriminate progressive supranuclear palsy (PSP) from the subset of Parkinson's disease patients who lack tremor (akinetic-rigid or PD-postural instability and gait disorder PIGD subtype), and from age-related oculomotor changes. We investigated the feasibility of a camera-less computerized behavioral saccade latency paradigm previously validated in PD to discriminate probable PSP-Richardson syndrome (PSP-RS) from PD-PIGD and age-matched controls. METHODS: In this proof-of-concept case-control study, reflexive saccade latencies were measured in 5 subjects with probable PSP-RS, 5 subjects with PD-PIGD subtype, and 5 age-matched controls using the behavioral paradigm. The battery was repeated approximately one month later. All subjects were examined off levodopa by a movement disorders neurologist and by an ophthalmologist, who also performed a dilated eye exam. RESULTS: Vertical prosaccade latencies were longer in the PSP group (median = 903 ms) relative to PD (median = 268 ms) and control groups (median = 235 ms), with no overlap between groups (100% accuracy). PSP subjects also had larger vertical-horizontal discrepancies than comparison groups. Test-retest reliability for the behavioral saccade measures was good (interclass correlation coefficient = 0.948; 95% confidence interval [0.856, 0.982]), and the measures strongly correlated with clinical ratings. CONCLUSIONS: Computerized behavioral measurement of reflexive saccade latency is feasible in PSP, and potentially discriminates probable PSP-RS from the PD-PIGD subtype. Findings from this proof-of-concept study support utility of the approach for obtaining objective saccade metrics in clinical evaluations and for tracking change in future, larger trials of moderately advanced PSP. Future studies should also examine the behavioral paradigm in earlier presentations of PSP and other subtypes of PSP.

Combat ocular trauma visual outcomes during operations iraqi and enduring freedom.

OBJECTIVE: To report the visual and anatomic outcomes as well as to predict the visual prognosis of combat ocular trauma (COT) during Operations Iraqi and Enduring Freedom. DESIGN: Retrospective, noncomparative, interventional, consecutive case series. PARTICIPANTS: Five hundred twenty-three consecutive globe or adnexal combat injuries, or both, sustained by 387 United States soldiers treated at Walter Reed Army Medical Center between March 2003 and October 2006. METHODS: Two hundred one ocular trauma variables were collected on each injured soldier. Best-corrected visual acuity (BCVA) was categorized using the ocular trauma score (OTS) grading system and was analyzed by comparing initial and 6-month postinjury BCVA. MAIN OUTCOME MEASURES: Best-corrected visual acuity, OTS, and globe, oculoplastic, neuro-ophthalmic, and associated nonocular injuries. RESULTS: The median age was 25+/-7 years (range, 18-57 years), with the median baseline OTS of 70+/-25 (range, 12-100). The types of COT included closed-globe (n = 234; zone 1+2, n = 103; zone 3, n = 131), open-globe (n = 198; intraocular foreign body, n = 86; perforating, n = 61; penetrating, n = 32; and rupture, n = 19), oculoplastic (n = 324), and neuro-ophthalmic (n = 135) injuries. Globe trauma was present in 432 eyes, with 253 eyes used for visual acuity analysis. Comparing initial versus 6-month BCVA, 42% of eyes achieved a BCVA of 20/40 or better, whereas 32% of eyes had a BCVA of no light perception. Closed-globe injuries accounted for 65% of BCVA of 20/40 or better, whereas 75% of open-globe injuries had a BCVA of 20/200 or worse. The ocular injuries with the worst visual outcomes included choroidal hemorrhage, globe perforation or rupture, retinal detachment, submacular hemorrhage, and traumatic optic neuropathy. Additionally, COT that combined globe injury with oculoplastic or neuro-ophthalmologic injury resulted in the highest risk of final BCVA worse than 20/200 (odds ratio, 11.8; 95% confidence interval, 4.0-34.7; P<0.0005). Nonocular injuries occurred in 85% of cases and included traumatic brain injury (66%) and facial injury (58%). Extremity injuries were 44% (170 of 387 soldiers). Amputation is a subset of extremity injury with 12% (46 of 387) having sustained a severe extremity injury causing amputation. CONCLUSIONS: Combat ocular trauma has high rates of nonocular injuries with better visual outcomes in closed-globe compared with open-globe trauma. The OTS is a valid classification scheme for COT and correlates the severity of injury with the final visual acuity and prognosis. Globe combined with oculoplastic or neuroophthalmologic injuries have the worst visual prognosis.

Periorbital nodular fasciitis arising during pregnancy.

Nodular fasciitis (NF) is a benign proliferation of fibroblasts and myofibroblasts that rarely occurs in the periorbital region. We report what we believe to be the first case of periorbital NF associated with pregnancy. A case of intravascular fasciitis, a NF variant, has been reported during pregnancy, but it was not located in the periorbital region. A weak presence of estrogen receptors has been reported in NF. This may make it more susceptible to the hormone-related changes during pregnancy and contribute to the development of the lesion by stimulating fibroblasts and smooth muscle cell types. Although rare, NF should be considered in the differential diagnosis of periorbital soft-tissue masses arising during pregnancy.

Residency training in refractive surgery.

PURPOSE: To evaluate resident refractive surgery caseload and surgical outcomes in an academic medical center. SETTING: Walter Reed Army Medical Center, Washington, DC, USA. DESIGN: Comparative case study. METHODS: Keratorefractive procedures performed by residents at the Walter Reed Center for Refractive Surgery between 2002 and 2010 were reviewed. Outcomes of surgeries performed by the graduating classes of 2008 to 2010 were compared with those of cases performed by staff. The uncorrected distance visual acuity (UDVA), manifest refraction spherical equivalent, corrected distance visual acuity (CDVA), and complications were analyzed. RESULTS: Between 2002 and June 2010, residents performed 1566 procedures (1414 photorefractive keratectomy [PRK], 152 laser in situ keratomileusis), for a mean of 20.2 procedures from 2002 to 2004, 51.6 from 2005 to 2007, and 99.9 from 2008 to 2010. Outcomes analysis was performed on 333 resident eyes and 977 staff eyes treated between 2008 and June 2010. Six months postoperatively, 96.1% of resident-treated eyes and 94.6% of staff-treated eyes had a UDVA 20/20 or better (P=.312) and 61.3% and 64.3%, respectively, had a UDVA 20/15 or better (P=.324). The percentage of eyes within ±0.50 diopter of emmetropia at 6 months was 94.0% for residents and 91.1% for staff (P=.105). The postoperative CDVA was within 2 lines of preoperative baseline in all resident cases and 99.8% of staff cases (P=.999). CONCLUSIONS: Resident experience grew steadily over the period studied. Overall safety and efficacy of resident-performed surgery, albeit mainly PRK based, matched that of fellowship-trained refractive surgeons.

Rectus abdominus free flap in the reconstruction of the orbit following subtotal exenteration.

An 18-year-old woman with recurrent embryonal rhabdomyosarcoma underwent a right subtotal exenteration sparing the eyelids and conjunctiva to remove the tumor. A rectus abdominus muscle free flap was secured to the right temporalis muscle. The temporalis muscle was then advanced into the temporal fossa defect and the rectus abdominus flap placed into the right orbital cavity and right maxillary sinus. An ocular conformer was then placed and a lateral tarsorrhaphy was performed. This surgical technique provides rapid socket rehabilitation with good cosmesis and enables the use of a standard ocular prosthesis.

Ophthalmic artery occlusion in relapsing polychondritis.

PURPOSE: To describe ophthalmic artery occlusion in a patient with relapsing polychondritis. METHODS: Observational case report RESULTS: : An acute episode of relapsing polychondritis caused ophthalmic artery occlusion with resultant visual acuity of no light perception. CONCLUSION: Ophthalmic artery occlusion can occur in patients with relapsing polychondritis. Patients with relapsing polychondritis need close follow-up to exclude severe vascular disease.

The ocular manifestations of atopic dermatitis and rosacea.

Atopic dermatitis and rosacea are chronic diseases that have both dermatologic and ocular manifestations. The occurrence of ocular disease is often proportionately higher than that of dermatologic disease. Even if the skin abnormalities appear well controlled, these patients require ophthalmic evaluation as well. Optimal management usually requires a team approach that includes internists, dermatologists, and ophthalmologists. Both disorders are characterized by acute exacerbations and require maintenance therapy for control. Exacerbations need aggressive treatment to limit ocular signs and symptoms and to reduce ocular inflammation that can lead to permanent visual loss. Topical corticosteroid use, although at times needed, should be minimized for both disorders. Future research will continue to emphasize the use of steroid-sparing and immune-modulating agents that have the potential to provide long-lasting anti-inflammatory control with a more favorable side-effect profile.

Adult orbital xanthogranuloma with associated adult-onset asthma.

: The authors report a case of adult orbital xanthogranuloma with associated adult-onset asthma in a 44-year-old man. Adult orbital xanthogranuloma was diagnosed on the basis of the clinical findings of bilateral, indurated, yellow eyelid lesions in a patient presenting with adult-onset asthma. Incisional biopsy of the eyelid lesions demonstrated a diffuse histiocytic infiltrate of the orbit and Touton giant cells without evidence of necrobiosis. Systemic evaluation failed to show evidence of bone lesions or paraproteinemia. When patients present with atypical indurated yellow eyelid lesions, a biopsy should be considered. If Touton giant cells are present, a systemic evaluation should be undertaken to rule out both Erdheim-Chester disease and necrobiotic xanthogranuloma. If no systemic findings are present, other than the possibility of adult-onset asthma, the rare entity of adult orbital xanthogranuloma should be considered.

Ocular surface, ocular adnexal, and lacrimal complications associated with the use of systemic 5-fluorouracil.

PURPOSE: To determine the prevalence rates and associated characteristics of patients who have ocular surface, ocular adnexal, and lacrimal complications associated with the systemic use of the cancer chemotherapeutic agent 5-Fluorouracil (5-FU). METHODS: An exposure-based cohort study was designed. Adult patients who had completed at least 3 months of systemic 5-FU therapy within the past 5 years were eligible for enrollment. Study subjects had a detailed medical history taken with emphasis on preexisting conditions known to be associated with the development of ocular surface, ocular adnexal, and lacrimal complications. An ocular examination was then performed. A complete nasolacrimal system evaluation was performed if symptoms or findings were identified. The prevalence was then determined for each ocular symptom and each ocular finding identified that was not present pretreatment. An exploratory analysis was then performed to identify patient characteristics that might influence the likelihood of developing any of the above complications. RESULTS: Fifty-two patients were enrolled in the study. The prevalence rates of the following ocular abnormalities were calculated: ocular irritation, 5.8%; blepharitis, 3.8%; conjunctivitis, 3.8%; keratitis, 3.8%; eyelid dermatitis, 5.8%; cicatricial ectropion, 1.9%; tearing, 26.9%; punctal-canalicular stenosis, 5.8%; and blurred vision, 11.5%. Blacks had tearing at a significantly higher rate when compared with whites (P = 0.022, 2-sided Fisher exact test). Three patients had permanent complications that will require surgery for correction. Of the 7 patients who had a single abnormality, 6 had tearing and one had eyelid dermatitis. All of the 8 patients who had multiple findings had tearing as one of their abnormalities. CONCLUSIONS: Ninety-three percent of the patients who had an ocular abnormality had tearing as one of the complications. Patients who are receiving systemic 5-FU and begin to tear should have an ocular examination, looking for ocular surface, ocular adnexal, and lacrimal complications.
