Comparison of Revision Rates of Anterior- and Posterior-Approach Ptosis Surgery: A Retrospective Review of 1519 Cases.

PURPOSE: To compare revision rates for ptosis surgery between posterior-approach and anterior-approach ptosis repair techniques. METHODS: This is the retrospective, consecutive cohort study. All patients undergoing ptosis surgery at a high-volume oculofacial plastic surgery practice over a 4-year period. A retrospective chart review was conducted of all patients undergoing posterior-approach and anterior-approach ptosis surgery for all etiologies of ptosis between 2011 and 2014. Etiology of ptosis, concurrent oculofacial surgeries, revision, and complications were analyzed. The main outcome measure is the ptosis revision rate. RESULTS: A total of 1519 patients were included in this study. The mean age was 63 ± 15.4 years. A total of 1056 (70%) of patients were female, 1451 (95%) had involutional ptosis, and 1129 (74.3%) had concurrent upper blepharoplasty. Five hundred thirteen (33.8%) underwent posterior-approach ptosis repair, and 1006 (66.2%) underwent anterior-approach ptosis repair. The degree of ptosis was greater in the anterior-approach ptosis repair group. The overall revision rate for all patients was 8.7%. Of the posterior group, 6.8% required ptosis revision; of the anterior group, 9.5% required revision surgery. The main reason for ptosis revision surgery was undercorrection of one or both eyelids. Concurrent brow lifting was associated with a decreased, but not statistically significant, rate of revision surgery. Patients who underwent unilateral ptosis surgery had a 5.1% rate of Hering's phenomenon requiring ptosis repair in the contralateral eyelid. Multivariable logistic regression for predictive factors show that, when adjusted for gender and concurrent blepharoplasty, the revision rate in anterior-approach ptosis surgery is higher than posterior-approach ptosis surgery (odds ratio = 2.08; p = 0.002). CONCLUSIONS: The overall revision rate in patients undergoing ptosis repair via posterior-approach or anterior-approach techniques is 8.7%. There is a statistically higher rate of revision with anterior-approach ptosis repair.

Lacrimal intubation during dacryocystorhinostomy utilizing the STENTube.

The traditional use of the Crawford tube for lacrimal intubation during dacryocystorhinostomy (DCR) carries several drawbacks. We describe the use of the STENTube for DCR intubation and detail its advantages. Retrospective, noncomparative, interventional case series; 313 patients with nasolacrimal duct obstruction (NLDO) underwent 339 DCRs (216 external, 123 endonasal) with the STENTube from January 2007 - June 2013 by 5 surgeons (RS, QN, TS, SB, TN) across 3 institutions (SUNY Downstate Medical Center, Texas Oculoplastics Consultants, and Moorfields Eye Hospital). Study outcome measures included patient demographics, surgical complications, and epiphora improvement/resolution. 206 (66%) females and 107 (34%) males had a mean age of 63 years (range 2-94 years). Distribution of diagnoses included: 314 complete idiopathic acquired NLDO, 20 partial idiopathic acquired NLDO, and 5 congenital complete NLDO. 316 (93%) were primary DCRs and 23 (7%) were revisions. Epiphora improved in 312 (92%) cases with 294 (86%) experiencing resolution with patent lacrimal irrigation at a mean last follow-up of 9.4 months. Twenty-eight (8%) patients experienced surgical complications with 16 (5%) experiencing tube prolapse, and 20 (6%) requiring re-operation. The STENTube represents a simple method for lacrimal intubation during external or endonasal DCR at a comparable cost to the Crawford tube. It allows for low prolapse rates without the need for additional endonasal fixation procedures, resulting in a simple and comfortable post-operative extraction without risk of lacrimal trauma. The STENTube is our preferred intubation technique during DCR, and should be considered by oculofacial surgeons performing DCR with intubation.

Bilateral lacrimal gland disease: clinical features of 97 cases.

OBJECTIVE: Bilateral lacrimal gland (LG) disease is a unique presentation that can result from varied causes. We reviewed the diagnoses, clinical features, and outcomes of 97 patients with this entity. DESIGN: Case series. PARTICIPANTS: Ninety-seven patients with bilateral LG disease. METHODS: Retrospective review and statistical analysis using analysis of variance and the Fisher exact test. MAIN OUTCOME MEASURES: Patient demographics, clinical features, diagnostic testing, diagnosis, and treatment. RESULTS: Patient age ranging from 8 to 84 years (mean, 46 years). The predominant gender was female (77%), and race included black (49%), white (38%), and Hispanic (12%) patients. Diagnoses fell into 4 categories: inflammatory (n = 51; 53%), structural (n = 20; 21%), lymphoproliferative (n = 19; 20%), and uncommon (n = 7; 7%) entities. The most common diagnoses included idiopathic orbital inflammation (IOI; n = 29; 30%), sarcoidosis (n = 19; 20%), prolapsed LG (n = 15; 15%), lymphoma (n = 11; 11%), lymphoid hyperplasia (n = 8; 8%), and dacryops (n = 5; 5%). Inflammatory conditions were more likely in younger patients (P<0.05) and in those with pain (P<0.001) and mechanical blepharoptosis (P<0.01) at presentation, whereas lymphoma was more common in older patients (P<0.001) without active signs of inflammation at presentation. Black patients were more likely to have sarcoidosis (P<0.01). Laboratory results showed high angiotensin converting enzyme level being significantly more likely in patients with sarcoidosis (P<0.05). However, sensitivity was limited to 45%, with 25% of patients diagnosed with IOI also demonstrating positive results. Corticosteroid therapy was the treatment of choice in 38 cases, corresponding to resolution of symptoms in 29% and improvement in an additional 32%. Overall, chronic underlying disease was found in 71% of patients, among whom 26% achieved a disease-free state, whereas 3% succumbed to their underlying disease. CONCLUSIONS: The cause of bilateral lacrimal gland disease most commonly was inflammatory, followed by structural and lymphoproliferative. Patient characteristics and clinical presentations were key features distinguishing between competing possibilities. Despite local control with corticosteroids or radiotherapy, underlying disease continued in 71% of patients and led to death in 3%.

Isolated globe rupture without concomitant eyelid laceration or orbital trauma following facial dog bite injury in a child.

PURPOSE: Facial dog bites often cause periorbital trauma; however, the globe is rarely damaged. Most globe injury following dog bites results from unusual circumstances and typically presents with concomitant periorbital and ocular adnexal injuries. OBSERVATIONS: The case presented is a rare presentation of isolated globe rupture without orbital trauma following facial dog bite in a child without history or evidence of decreased blink reflex, mental deficiency, or substance use. CONCLUSIONS AND IMPORTANCE: Ophthalmic investigation is warranted in all pediatric periorbital dog bite injuries, even in the setting of minimal or absent periorbital trauma. As additional blunt trauma to the globe in the immediate recovery period resulted in a second open globe injury, the critical importance of protective eyewear, activity restriction, and judicious corneal suture removal postoperatively following repair of open globe injury is discussed.

Severe eye injuries in the war in Iraq, 2003-2005.

PURPOSE: To document the incidence and treatment of patients with severe ocular and ocular adnexal injuries during Operation Iraqi Freedom. DESIGN: Retrospective hospital-based observational analysis of injuries. PARTICIPANTS: All coalition forces, enemy prisoners of war, and civilians with severe ocular and ocular adnexal injuries. METHODS: The authors retrospectively examined severe ocular and ocular adnexal injuries that were treated by United States Army ophthalmologists during the war in Iraq from March 2003 through December 2005. MAIN OUTCOME MEASURES: Incidence, causes, and treatment of severe ocular and ocular adnexal injuries. RESULTS: During the time data were gathered, 797 severe eye injuries were treated. The most common cause of the eye injuries was explosions with fragmentation injury. Among those injured, there were 438 open globe injuries, of which 49 were bilateral. A total of 116 eyes were removed (enucleation, evisceration, or exenteration), of which 6 patients required bilateral enucleation. Injuries to other body systems were common. CONCLUSIONS: Severe eye injuries represent a significant form of trauma encountered in Operation Iraqi Freedom. These injuries were most commonly caused by explosion trauma.

Tarsal switch levator resection for the treatment of blepharoptosis in patients with poor eye protective mechanisms.

PURPOSE: The authors report the use of a tarsal switch levator resection procedure that opens the palpebral fissure while reducing the risk of postoperative exposure in ptosis patients with poor eye protective mechanisms. DESIGN: Retrospective noncomparative case series. PARTICIPANTS: Fifteen consecutive patients of 2 surgeons at Texas Oculoplastic Consultants from July 1997 through July 2005. INTERVENTION: A composite tarsal-levator-conjunctival graft was taken from the upper eyelid and was transferred to the lower eyelid. MAIN OUTCOME MEASURES: Clinical assessment of postoperative exposure keratopathy and position of palpebral fissure relative to visual axis. RESULTS: A composite tarsal-levator-conjunctival graft was taken from the upper eyelid and was transferred to the lower eyelid in 26 eyelids of 15 patients. One patient was excluded because of lack of follow-up. There were 7 men and 7 women; the age ranged from 20 months to 74 years. The average duration of follow-up was 34 months, with a range of 3 to 85 months. The palpebral fissure was moved cephalad in all patients, improving their head position and unmasking their visual axis in primary gaze. One patient experienced exposure symptoms after surgery and required recession of the levator aponeurosis of both upper eyelids. Overall patient satisfaction was excellent. CONCLUSIONS: The tarsal switch levator resection procedure elevates both the upper and lower eyelids a predetermined amount. This displaces the palpebral fissure superiorly, effectively opening the visual axis in primary gaze and decreasing the risk of postoperative exposure problems in patients with diminished eye protective mechanisms.

Paradoxical use of frontalis muscle and the possible role of botulinum a toxin in permanent motor relearning.

PURPOSE: To report 7 patients with paradoxical use of the frontalis muscle despite postsurgical correction of ptosis with good postoperative eyelid position. Successful treatment with botulinum A toxin facilitated motor relearning and cessation of muscle contraction. DESIGN: Interventional case series. PARTICIPANTS: Seven patients, in 2 eye-plastic clinics, who underwent successful surgical correction of upper eyelid ptosis. METHODS: Review of clinical history, clinical photographs, treatment, and follow-up. MAIN OUTCOME MEASURES: Frontalis muscle contraction and upper eyelid position. RESULTS: Patients underwent successful surgical correction of ptosis but continued using the frontalis muscle despite good eyelid position postoperatively. Frontalis contraction ceased spontaneously in 2 patients, but required botulinum A toxin injection in 5. The effects of a single treatment of botulinum A toxin lasted from 3 months to 2 years, longer than the expected effect of the toxin. CONCLUSION: Patients with long-standing eyelid ptosis may paradoxically continue utilizing the frontalis after successful surgical correction and despite good postoperative eyelid position. Cessation of frontalis contraction can be achieved with a single injection of botulinum A toxin. We hypothesize that chemodenervation, achieved with the toxin, may influence the central nervous system to relearn the set point for muscle contraction and may be associated with permanent motor relearning. Spontaneous resolution of muscle contraction can occur in the first months after surgery.

Positron emission tomography scanning in essential blepharospasm.

PURPOSE: To localize in the brain using positron emission tomography neuroimaging with (18)fluorodeoxyglucose [PET ((18)FDG)] differences in glucose metabolism between patients with essential blepharospasm (EB) and controls. DESIGN: Prospective case-control study. METHODS: Positron emission tomography neuroimaging with (18)fluorodeoxyglucose was performed in 11 patients with EB and 11 controls matched for age and gender. Global analysis of images was used to localize differences in glucose metabolism between groups. RESULTS: Multiple cortical and subcortical abnormalities were observed in EB patients in comparison with controls. Cortical areas with the largest and most significant clusters of increased glucose uptake were the inferior frontal gyri, right posterior cingulate gyrus, left middle occipital gyrus, fusiform gyrus of the right temporal lobe, and left anterior cingulate gyrus. Cortical areas with the largest and most significant clusters of decreased glucose uptake were the inferior frontal gyri, ventral to the area of increased glucose metabolism. Subcortical abnormalities, consisting of increased glucose uptake, involved the right caudate and consisting of decreased glucose uptake, involved the left inferior cerebellar hemisphere and thalamus. CONCLUSIONS: Global analysis of positron emission tomography neuroimaging with (18)fluorodeoxyglucose neuroimaging in EB patients in comparison with controls demonstrates a pattern of abnormalities involving several cortical and subcortical areas that control blinking, including the inferior frontal lobe, caudate, thalamus, and cerebellum.

Congenital upper eyelid ectopic cilia.

Ectopic eyelid cilia is an uncommon congenital anomaly typically occuring in otherwise healthy children. It is asymptomatic, but parents may wish surgical excision for cosmetic benefits. The authors describe three cases of ectopic upper eyelid cilia, surgical intervention, and follow-up results.

Broad fascia fixation enhances frontalis suspension.

PURPOSE: To report the use of a modified frontalis suspension procedure for congenital ptosis patients with minimal to no levator function. METHODS: Retrospective, non-comparative case series of frontalis suspension by 2 surgeons over a 21-year period. RESULTS: Frontalis suspension with broad fascia fixation was performed on 48 eyelids of 25 patients. All patients had visual obscuration due to blepharoptosis with only 0 mm to 2 mm of measurable levator function. Age ranged from 3 to 13 years. Minimum length of follow-up was 6 months (range, 6-174 months). The palpebral fissure was increased in all patients, improving their head position and unmasking their visual axis in primary gaze. Postoperatively, all patients developed transient exposure symptoms. There were no migrations, extrusions, infections, or granulomas. All patients achieved a satisfactory postoperative result based on eyelid position, function, and contour. CONCLUSIONS: This modified frontalis suspension procedure maximizes frontalis muscle recruitment, creating powerful eyelid elevation with stable effect over time. The technique minimizes other procedures' pitfalls and advances in cosmesis are achieved with enhanced eyelid crease formation and adjustable eyelid contour.

A permanent and reversible procedure to block tear drainage for the treatment of dry eye.

PURPOSE: To describe a technique of canalicular ligation and report observations on 59 consecutive surgeries. METHODS: Retrospective, non-comparative case series of canalicular ligation by 3 surgeons over a 7-year period. RESULTS: Fifty-nine eyelids of 29 patients (2 men and 27 women) underwent canalicular ligation for the treatment of severe dry eyes. Patient age ranged from 34 to 90 years. Average length of follow-up was 20 months. There were no complications. Ninety-one percent of patients noted an improvement in their symptoms. Two patients developed symptomatic epiphora more than 1 year postoperatively and both underwent successful reversal. CONCLUSIONS: Canalicular ligation is an effective technique for punctal occlusion in patients with severe dry eyes. It combines surgical ease with excellent cosmetic outcomes.

The porous polyethylene (Medpor) spherical orbital implant: a retrospective study of 136 cases.

PURPOSE: To evaluate complications and risk factors associated with the placement of wrapped and unwrapped porous polyethylene (PP) spherical implants after evisceration, enucleation, or secondary implantation. METHODS: A retrospective, interventional, noncomparative case series of consecutive cases of PP implant placement after anophthalmic socket surgery performed by three surgeons over a 5-year period. A PP spherical implant was placed in 133 patients, 61 women (2 bilaterally) and 72 men (1 bilaterally). There were 91 enucleations, 30 eviscerations, and 15 secondary implant placements. Sixty-six (48.5%) implants were wrapped prior to placement. Parameters evaluated included: age, sex, prior ocular surgery or radiation treatment, indications for surgery, procedure performed, size of PP sphere, material used to wrap the implant, and complications. RESULTS: A total of 17 of 136 (12.5%) cases had documented postoperative complications, with implant exposure being the most common. In 5 patients (3.7%), implant exposure developed: 1 after evisceration and 4 after primary enucleation. Three of the five exposures were small and resolved with either observation alone or in one case with surgical revision of the socket. In two cases, the exposures were large enough that removal of the implant was indicated, one after evisceration and the other after enucleation with placement of a wrapped PP sphere. CONCLUSIONS: Our series revealed no significant difference in exposure rate between wrapped and unwrapped PP sphere implants, nor was the exposure rate affected by whether an eye was eviscerated or enucleated.

Use of bioglass for orbital volume augmentation in enophthalmos: a rabbit model (oryctolagus cuniculus).

PURPOSE: To investigate the clinical and histologic response of Novabone-C/M as an osteoproductive alloplastic implant for volume augmentation in the orbit in the treatment of enophthalmos and to compare its outcome alone versus its use in combination with autogenous bone or Medpor granules. METHODS: Novabone-C/M, a bioactive silicone glass material, was implanted in the subperiosteal space of the left orbit of 12 New Zealand White rabbits. The animals were divided into 3 groups, each with 4 animals, based on the material implanted in the orbit: group 1, Novabone alone; group 2, Novabone plus Medpor granules; and group 3, Novabone plus autogenous bone fragments. All rabbits were studied clinically, radiographically, and histologically at 1-, 3-, and 6-month intervals. Animals underwent preoperative and postoperative computed tomography (CT) with 3-dimensional reconstruction, proptosis measurements, and volumetric analysis. Orbit specimens were studied histologically with mineralized bone stain (MIBS) to look for bone formation, reactivity, infection, implant resorption, and migration. RESULTS: There were no signs of significant inflammation or infection. Subcutaneous migration of the implant was seen radiographically but not clinically in groups 1 and 3. Induced proptosis averaged 2.5 mm (at 1 month) and showed regression in all groups over a 6-month period but was not statistically significant. Implant volume was markedly reduced in all groups, averaging 69% in group 1, 37% in group 2, and 59% in group 3 at 6 months. New bone formation and bone remodeling was present in all 3 groups at 3 months and only in group 2 at 6 months. The rate and amount of implant remodeling and bone formation was greatest in the Novabone/Medpor group (group 2). CONCLUSIONS: Bioglass particulate is biocompatible, easy to use in the orbit, and stimulates bone growth. Bioglass is associated with volume loss and migration over 6 months and may not provide adequate volume augmentation in the orbit when used alone for the treatment of enophthalmos. The duration and amount of bone formation may be enhanced when Novabone is used in conjunction with Medpor.
