Current practice trends for lacrimal gland neurotoxin in the management of epiphora-a BOPSS survey.

PURPOSE: Injection of botulinum neurotoxin A (BoNTA) to the lacrimal gland (LG) offers a simple and effective treatment in the management of epiphora. However, there is little data on current practice trends or uptake as an alternative to surgery. This study assesses current practice trends of such treatment amongst BOPSS (British Oculoplastic Surgery Society) members. METHODS: All consultant BOPSS members were invited to participate in a web-based survey which consisted of 5 questions, with a reminder invitation to participate. The role, dose, potential side effects, use as an alternative to surgical intervention, and impact on service delivery were assessed. RESULTS: Fifty-one BOPSS consultants (43% uptake) completed the survey. Ninety percent of respondents were regularly using LG BoNTA in their management of epiphora. The main indicators for considering BoNTA use were medical comorbidities and elderly patients. The mean first treatment dose of Botox® was 3.6 units (SD 1.5). Diplopia and ptosis complications were always discussed in the consent for treatment in addition to dry eye. Twenty-five percent of surgeons reported doing less conjunctivo-dacryocystorhinostomies (cDCR) due to the availability of LG BoNTA. No respondents felt that the requirement for repeated BoNTA treatments was impacting on their service delivery. CONCLUSION: Uptake of LG BoNTA in the management of epiphora is at a similar rate to all other available treatments. As a result, respondents are performing less surgical procedures, particularly cDCR in patients at higher surgical morbidity.

Cutaneous pleomorphic adenoma of the periocular region - a case series.

Mixed tumour of the skin is a rare entity also known as chondroid syringoma and pleomorphic adenoma. These usually present as slow-growing skin nodules with a smooth surface, clear boundaries, and no ulceration. Case series exist describing pleomorphic adenomas in the periocular region including the lids and orbit, separate to the more familiar lacrimal gland pleomorphic adenoma. These may arise from accessory or ectopic lacrimal gland tissue but in the eyelids are more likely to arise from sweat glands in the skin. Histopathological analysis of these lesions is important to identify complete excision, minimising recurrences and in identifying rare but potential malignant transformation. We describe the clinical features and outcomes in three cases of pleomorphic adenoma with two at the medial canthus (including one recurrence) and one in the brow region.

Incidence of canalicular closure with endonasal dacryocystorhinostomy without intubation in primary nasolacrimal duct obstruction.

PURPOSE: To describe the incidence of canalicular closure with powered endonasal dacryocystorhinostomy (DCR) without canalicular intubation in primary acquired nasolacrimal duct obstruction (PANDO). DESIGN: A single-surgeon, prospective, nonrandomized, noncomparative, interventional case series. PARTICIPANTS: Consecutive patients attending a specialist clinic of an oculoplastic surgeon (DS) with radiologically confirmed diagnosis of PANDO. Cases of canalicular disease were excluded. METHODS: Patients with radiologically confirmed PANDO without canalicular involvement underwent endonasal DCR without intubation. The operation was performed by 1 surgeon (DS) and follow-up was at 4 weeks and 12 months. MAIN OUTCOME MEASURES: Outcomes were recorded as subjective symptomatic relief at 12 months and endoscopic evidence of ostium patency and canalicular patency. RESULTS: There were 132 cases that fulfilled the inclusion criteria. Three cases were lost to follow-up. Preoperatively, 96.3% of cases had Munk scores of >2. Of the 129 cases, 127 (98.5%) had endoscopic evidence of a patent ostium with a positive endoscopic dye test at the 12-month follow-up. All cases had a patent canalicular system as demonstrated by syringing and probing. Of the 129 cases, 117 (90.7%) had subjective improvement of epiphora at 12 months with 88.4% of cases reporting Munk scores of ≤1. CONCLUSIONS: In this prospective series of nonintubation for PANDO, there were no cases of canalicular closure or stenosis at 12 months. Anatomic and functional success was similar to reported outcomes for DCR with intubation for PANDO. We advocate that routine intubation for the purpose of maintaining canalicular patency is not necessary when performing endonasal DCR in PANDO.

Endoscopic transcaruncular repair of large medial orbital wall fractures near the orbital apex.

PURPOSE: To study the suitability of an endoscopic transcaruncular approach (ETA) for repair of large medial orbital wall fractures (MOWFs) near the orbital apex. DESIGN: A retrospective, noncomparative case series with description of the surgical technique. PARTICIPANTS: Ninety-three consecutive patients (93 orbits) with large isolated MOWFs near the orbital apex. METHODS: The isolated MOWFs were determined by computed tomography (CT) scans of the orbit in all patients. All patients underwent fracture repair by an ETA, and the vertical and horizontal dimensions of the defects were measured during surgery. Porous polyethylene sheets (1.0 mm thick) were used to repair the bony defects. Patients were followed for 6 to 15 months. MAIN OUTCOME MEASURES: Size of vertical and horizontal fracture defects, rate of complete repair of the fracture defects, correction of enophthalmos, resolution of diplopia, and complications 6 months after surgery. RESULTS: All surgeries were completed uneventfully. The mean postoperative follow-up time was 9.7 ± 3.0 months. Under direct endoscopic visualization, all entrapped and herniated orbital contents were released and reposited, the entire boundary of the fractures were exposed adequately, and the implants were placed to overlie all edges of the fracture stably in all cases. The vertical and horizontal fracture defects measured during surgeries ranged from 16 to 30 mm and from 25 to 34 mm, respectively. Six months after surgery, complete reconstruction of the bony defects was demonstrated by orbital CT scans, and symmetry of the both eyes was acquired in 92 of 93 patients (98.9%). Of 30 patients with significant preoperative enophthalmos of more than 2 mm, 29 (96.7%) were corrected, with a mean improvement of 3.37 ± 0.77 mm. Diplopia within the 30° visual field of the gaze was resolved in 40 of 43 patients (93.0%). Three patients (7.0%) had residual diplopia on medial gaze because of presumed paralysis of the medial rectus muscle. Intraorbital hemorrhage occurred in 1 patient the day after surgery and resolved with conservative treatment. CONCLUSIONS: The ETA seems to be a useful method for recovery of the normal anatomic features of the orbits for patients with large MOWFs near the orbital apex.

Management of upper eyelid cicatricial entropion.

PURPOSE: There is a paucity of published data on the management of upper eyelid cicatricial entropion. We report on our results using such techniques as lamella repositioning, recession or augmentation and terminal tarsal rotation. DESIGN: Observational retrospective case series. PARTICIPANTS: Consecutive cases of upper eyelid cicatricial entropion of two specialist oculoplastic centres (Corneoplastic Unit, East Grinstead, UK and South Australian Institute of Ophthalmology, Adelaide, Australia) were reviewed over a 7-year period. METHODS: All patients underwent anterior lamellar repositioning or terminal tarsal rotation. MAIN OUTCOME MEASURES: Success was defined by two definitions: anatomical success was defined where the lid margin was restored to its normal position. Complete success was defined where there were no eyelashes touching the globe. Gain or loss (≤ or ≥2 Snellen lines) in best corrected visual acuity using a Snellen chart and resolution of any corneal epitheliopathy at final follow-up were also recorded (as graded by experienced oculoplastic consultants). RESULTS: Fifty-two procedures were performed on 41 patients (11 bilateral). All patients underwent either an anterior lamellar repositioning or a terminal tarsal rotation. Trachoma, previous upper lid surgery, Stevens-Johnson syndrome and meibomian gland dysfunction were the commonest underlying diagnoses. Ninety-eight per cent of the group had a normal anatomical lid position at follow-up. Nine eyelids (17%) of the group had recurrence of trichiasis. CONCLUSION: This large case series demonstrates that upper eyelid cicatricial entropion is managed effectively utilizing procedures that involve recession and reposition. We recommend that excision of tissue is avoided, especially in pathology that has a progressive immunological cicatricial drive.

The use of soft tissue expanders in periocular reconstruction: a case series.

PURPOSE: To describe the use of soft tissue expanders for periocular reconstruction in the presence of limited local tissue availability. METHODS: A retrospective case series of 5 patients who attended the Manchester Royal Eye Hospital. They presented a reconstructive challenge due either to the presence of periocular scarring or to a marked loss or limitation of normal local skin for reconstruction. The soft tissue expander (SOE-3624 device) was inserted under the skin and subcutaneous tissue at a site selected to provide the desired additional tissue. Over periods of time varying from 6 to 16 weeks, the soft tissue expander was gradually inflated with injections of sterile saline in the outpatient clinic. As soon as the desired amount of additional skin and subcutaneous tissue had been obtained, reconstructive surgery was undertaken. Functional and cosmetic results were the main outcomes of the intervention. RESULTS: Four of the patients had the device inserted in the lower eyelid or cheek area and one patient had the device inserted above the eyebrow. No episode of tissue necrosis occurred in our patients. All the devices were tolerated by the patients and were removed without any complications. The implant migrated in one patient, limiting the reconstructive surgery, and one patient had a lateral canthal dehiscence following reconstruction. All patients thought that the surgery had improved their cosmesis. No patient required any additional surgical procedures. CONCLUSIONS: The authors conclude that the SOE-3624 tissue expander represents a good option in providing additional tissue for periocular reconstruction, particularly in younger patients. It was well tolerated and effective in this series.

Visual acuity recovery in traumatic optic neuropathy following endoscopic optic nerve decompression: a case report.

A 59-year-old Chinese man presented with no light perception in the left eye 1 day following functional endoscopic sinus surgery. The patient underwent endoscopic optic nerve decompression with topical and systemic application of nerve growth factor and steroids after a failed trial of high-dose intravenous corticosteroids. Visual acuity improved to 20/25 at 3 weeks and remained stable at 9 months. Reports of full visual recovery are exceedingly rare following this functional endoscopic sinus surgery complication.

Endoscopic transethmoidal and transconjunctival inferior fornix approaches for repairing the combined medial wall and orbital floor blowout fractures.

PURPOSE: To assess the combination of an endoscopic transethmoidal approach (ETEA) and a transconjunctival inferior fornix approach (TIFA) for repairing combined orbital floor and medial wall blowout fractures (COF-MWBOFs). METHODS: Patients with unilateral COF-MWBOFs were randomized to 2 groups: ETEA combined with TIFA or medial canthal incision (MCI) combined with TIFA. Thin porous polyethylene sheets were implanted to cover the orbital defects. The postoperative follow-up time was 6 months. For both groups, degree of diplopia, enophthalmos, ocular motility, and complications were recorded and compared. RESULTS: Our study included 32 patients in the ETEA group and 27 patients in the MCI group. The time from trauma to surgery ranged from 10 to 48 days. The herniated orbital contents were completely reduced in 96.9% (31/32) of the ETEA group and in 77.8% (21/27) of the MCI group (P=0.040). At the 6-month review, the success rate of enophthalmos correction in the ETEA group achieved 96% (24/25), higher than that in the MCI group (66.7%, 12/18; P=0.015). The improvement of the enophthalmos was better in the ETEA group than in the MCI group (4.5±0.7 mm versus 3.2±1.2 mm) at 6 months (P=0.000). We found no difference in the resolution rate of diplopia within a 30-degree visual field or extraocular muscle function between the 2 groups. Complications in the MCI group included 1 patient with optic neuropathy after the procedure and 4 patients with medial canthal webbing. CONCLUSIONS: Endoscopic transethmoidal approach combined with TIFA is a promising technique for repairing extensive COF-MWBOFs.

A multi-centre case series investigating the aetiology of hypertrophic pachymeningitis with orbital inflammation.

INTRODUCTION: To describe our attempt in establishing a definitive diagnosis in patients with hypertrophic pachymeningitis in combination with orbital inflammatory disease and report on the outcome. MATERIALS AND METHODS: This was a retrospective case series of all patients presenting with hypertrophic pachymeningitis in association with orbital inflammation in 4 centres. Ophthalmic and neurological examination data, laboratory data, histology data, treatment plans and clinical outcome data were recorded. Patients underwent orbital/brain computed tomography and magnetic resonance imaging. RESULTS: Six patients were identified; the median age was 46.5 years. Headache was the commonest presenting symptom, followed by diplopia and reduced visual acuity. Three patients underwent orbital biopsy, 1 patient underwent dura mater biopsy, 1 patient underwent both and 1 patient underwent nasal biopsy. Four patients were diagnosed with Wegener granulomatosis and 2 patients with tuberculosis. Corticosteroid therapy was initiated in 4 patients, with steroid-sparing drugs added later. Two patients received anti-tuberculosis treatment and 1 patient was commenced on pulsed cyclophosphamide. On follow-up, 1 patient required an exenteration for a painful blind eye and 1 patient's visual acuity remained at no perception to light. One patient had complete resolution of symptoms on treatment, 1 patient had persistent reduced visual acuity and 1 patient was lost to follow-up. CONCLUSION: We postulate that the combination of orbital inflammation and pachymeningitis is strongly suggestive of Wegener granulomatosis, although it may take a number of years to confirm. Tuberculosis should also be considered.

Prostaglandin analogues: A double-edged sword in orbital glaucoma disease management.

INTRODUCTION: The authors describe benefits of the recognised adverse effects of prostaglandin analogues on periocular structures in patients with unilateral proptosis and intraocular pressure rise. This case points to intentional consideration of prostaglandin analogue therapy in this selected cohort of patients with secondary ocular hypertension and proptosis. CASE DESCRIPTION: A 70-year-old gentleman who presented with a 1-week history of a red and painful right eye associated with tortuous and dilated episcleral blood vessels. Visual acuity was unaffected. A diagnosis of idiopathic orbital inflammatory disease was made by extraocular muscle biopsy. Two weeks later, the patient presented with worsening pain, reduced vision and raised intraocular pressure. The secondary ocular hypertension was successfully treated with topical preserved eye drops, including latanoprost, a prostaglandin analogue. Over 6 months, the patient developed drop intolerance and punctate keratopathy leading to therapy non-adherence. Interestingly, the patient reported improvement in periocular appearance related to prostaglandin-associated periorbitopathy. Ocular surface disease and intraocular pressures were subsequently managed with preservative-free eye drops. CONCLUSION: Secondary ocular hypertension is not an uncommon consequence of orbital disease. Prostaglandin analogue can act as a double-edged sword in the management of raised intraocular pressure by reducing eye pressure at the cost of developing adverse effects of prostaglandin-associated periorbitopathy. These adverse effects however can be beneficial in the aesthetic rehabilitation of proptosis and associated exposure keratopathy in patients with unilateral orbital disease and probably should be sought as first line treatment in those with proptosis and raised intraocular pressure.

Extramedullary plasmacytoma arising from the lacrimal gland.

An 80-year-old man presented with an 8-week history of painless swelling in the right lacrimal gland region with infero-medial dystopia of the globe. The lesion was excised and histology confirmed an orbital plasmacytoma. Multiple myeloma screening was negative and a solitary extramedullary plasmacytoma arising from the lacrimal gland was diagnosed. The patient was subsequently treated with radiotherapy.

Difference in response to botulinum toxin type A treatment between patients with benign essential blepharospasm and hemifacial spasm.

BACKGROUND: Botulinum toxin (BTX) is the first-line treatment in managing benign essential blepharospasm (BEB) and hemifacial spasm (HFS). We wished to assess the difference in duration of effect and the number of BTX treatments required to treat patients with BEB and HFS. METHODS: A prospective study of patients attending the BTX clinic in Manchester Royal Eye Hospital over 6 months. All treatments were administered by a single experienced ophthalmologist. A questionnaire was completed for each patient. In patients with BEB where the BTX was injected bilaterally, one side was randomized to compare with HFS patients. Patient demographics, cumulative dose of BTX, duration of BTX effect with patient satisfaction and the number of previous BTX injections were recorded. RESULTS: Sixty-four patients were included in the study. The mean age was 60.8 years. Among them, 30 patients had BEB and 34 had HFS. Patients with HFS received a lower mean dose of BTX than patients with BEB (12.23 units vs. 16.2 units). The patients with HFS had a longer duration of effect than patients with BEB, with fewer BTX treatments. Of all patients, 90% with HFS and BEB were satisfied with the effect of their last BTX injection. Three unsatisfied patients in the BEB group were referred on for surgical management of their disorder. CONCLUSIONS: We have shown that patients with BEB have a shorter duration of effect with BTX and require more frequent BTX treatments than patients with HFS, highlighting that facial dystonias in patients with BEB is more challenging to manage.

Hypertrophic changes of the lower eyelid margin after hughes procedure for eyelid reconstruction: the management and outcomes.

PURPOSE: To describe the management of lower eyelid margin hypertrophy as a complication of the Hughes procedure for eyelid reconstruction. METHODS: A retrospective review of all patients with lower eyelid hypertrophy after Hughes procedure. Patient demographics, management, histologic findings, and outcomes were recorded. The patients underwent wedge excision of the hypertrophic segment of the eyelid with direct closure achieved in the majority of cases. RESULTS: Five patients were identified. The mean age at presentation was 66 years. The mean onset for the hypertrophic margin was 8.4 weeks after the Hughes flap. Four patients complained of ocular irritation and 1 patient had a constant ocular discharge. All patients were concerned by the appearance of the eyelid margin. Four patients received topical steroid treatment and 4 patients underwent triamcinolone subcutaneous injections with no improvement. The wedge excision was successful in 4 patients at the mean follow-up of 10 months, with no recurrence of the hypertrophic margin. One patient was reviewed in another center. CONCLUSION: The authors found no beneficial effect with topical or subcutaneous courses of steroids on eyelid margin hypertrophy. In situations of horizontal eyelid laxity, a full-thickness wedge excision offers a good means of removing the offending eyelid segment.

Tonopen versus Goldmann applanation tonometry for detecting restrictive thyroid eye disease.

PURPOSE: In thyroid eye disease (TED), intraocular pressure (IOP) measurements are taken in both the primary and upgaze positions to elicit restrictive muscle disease. The aim of this study was to assess whether the IOP when measured with the eyes in upgaze (the Goldmann applanation tonometer [GAT] head applanating the inferior/peripheral cornea) is similar when compared with the central corneal IOP in upgaze using the Tono-Pen XL. METHODS: IOP was measured with the GAT on the central cornea in primary gaze and on the inferior cornea in upgaze. IOP was measured with the Tono-Pen XL in the central cornea in both primary gaze and upgaze. The outcome measure was the difference in IOP readings between the GAT and the Tono-Pen XL for patients with restrictive TED. RESULTS: Fifty-two patients were included in the study; 31 patients with restrictive TED and 21 control patients. In the control group, there was no significant difference in Tono-Pen XL and GAT readings for both primary gaze and upgaze (p = 0.99). Both instruments detected an increase in IOP with upgaze in patients with restrictive TED compared with controls (p = 0.0006). There was no significant difference between the 2 instruments' readings in upgaze for patients with restrictive TED (p = 0.39). CONCLUSIONS: Both the GAT and the Tono-Pen XL can be used to establish IOP in patients with restrictive TED.

Can eyelid taping predict the benefit of a lateral tarsal strip procedure in patients with eyelid laxity and functional epiphora?

PURPOSE: To determine whether taping of the lower eyelid laterally and upward onto the temple region (to mimic a lateral tarsal strip procedure) can effectively predict whether lateral tarsal strip surgery will lead to resolution or improvement in functional epiphora by correcting eyelid laxity. METHODS: A case series of 28 eyes in 20 patients with symptomatic epiphora and equivocal lateral eyelid laxity were identified. The inclusion criteria included patent nasolacrimal systems on syringing with no other eyelid malposition or obvious cause for epiphora. Patients underwent taping of the lower eyelid using micropore tape to the temple region in the outpatient clinic for a period of 1 hour. The patients were asked to spend that time in conditions that would exacerbate their epiphora (e.g., outdoors). At the end of the hour the patients were recalled for subjective reassessment of epiphora. RESULTS: The mean age of the patients was 69 years. Eighteen patients (25 eyes) had subjective improvement in their epiphora when taped; this group was offered subsequent lateral tarsal strip surgery. Two patients (3 eyes) had no improvement in symptoms when taped. Postoperative follow-up showed decreased epiphora in 14 patients (20 eyes) of the 18 patients (25 eyes) operated. In 4 patients (5 eyes), although eyelid taping was beneficial, surgery did not resolve the epiphora. CONCLUSIONS: Temporary tightening of the lower eyelid with micropore tape to mimic the effect of lateral tarsal strip surgery can identify those patients who may benefit from an eyelid-tightening procedure. Patients who did not benefit from eyelid taping can avoid potentially unnecessary eyelid surgery.

The surgical management and outcomes for spheno-orbital meningiomas: a 7-year review of multi-disciplinary practice.

AIMS/PURPOSE: Spheno-orbital meningiomas account for 9% of all adult intracranial meningiomas. Complete resection is extremely difficult with this condition. We report on our experience in the surgical management of spheno-orbital meningiomas. METHODS: A retrospective review was performed of all patients with spheno-orbital meningiomas who underwent joint neurosurgical and ophthalmic procedures between January 2000 and December 2007. Radiological findings, presenting clinical signs, indications for surgery, surgical approach, histopathological findings, surgical complications and post-operative results were recorded. RESULTS: Twelve patients were included in the study. Visual function deterioration was the main indication for surgery. Six patients underwent an optic canal decompression along with their initial tumour resection and all 12 patients underwent an extensive lateral orbital wall decompression. Post-operatively 6 patients had reduced proptosis. Two patients had an improvement in their visual acuity, 5 patients had a stable visual acuity and 5 patients had a progressive deterioration in visual acuity following surgery. Six patients maintained a stable visual field. Cranial nerve palsy was the commonest post-operative complication. Three patients required postoperative fractionated radiotherapy. Three patients required further surgery. CONCLUSION: Spheno-orbital meningiomas are difficult tumours to manage. Surgical resection can reduce the degree of proptosis and stabilise visual function in patients with failing vision, although sustained improvement is difficult to achieve if the tumour behaves in an aggressive manner. The risk of post-operative visual loss is considerable, either due to surgery or tumour progression. Outcomes from surgical decompression may not necessarily be better than the natural history of these tumours.

The combination of intravitreal triamcinolone and phacoemulsification surgery in patients with diabeticfoveal oedema and cataract.

BACKGROUND: The management of diabetic patients with refractory macular oedema or patients with no adequate pre-operative view to administer laser treatment provide a challenge to the ophthalmologist. We wished to assess the use, safety and effect of intravitreal triamcinolone injection at the time of cataract surgery in patients with diabetic foveal oedema and sight limiting lens opacities. METHOD: This was a longitudinal non-randomised prospective pilot study in 18 eyes (12 patients). All patients had visually significant lens opacities and either persistent diabetic foveal oedema unresponsive to laser treatment-group A, or foveal oedema with no adequate pre-operative view for laser treatment- group B. The cataract surgery was carried out under full aseptic technique using a self-sealing temporal incision and a foldable acrylic lens. Intravitreal triamcinolone was given infratemporally pars plana at the completion of the cataract surgery. The patients were reviewed at day 5, 2 weeks, 2 months and then every 3 months as required. The Wilcoxin matched-pairs test was used to assess the significance of the improvement in visual acuity at 2 months. RESULTS: Twelve patients with a total of 18 eyes were included in the study. There were 10 patients (15 eyes) in group A and 3 patients (3 eyes) in group B. Preoperatively 16 of the 18 eyes had a visual acuity of 6/24 or worse. Postoperatively 83% of patients had completely dry foveae at 2 weeks. Best-corrected visual acuities at two months review ranged from 6/6 to CF with 9 eyes (50%) achieving 6/12 or better (7 eyes (47%) in group A and 2 eyes (67%) in group B). Three eyes had no recorded improvement in visual acuity, but no eyes had deterioration in acuity. The improvement in visual acuity was significant at p = 0.001. There were no significant sight threatening complications. CONCLUSION: Intravitreal triamcinolone has been shown to lead to an improvement in macular oedema and visual improvement in diabetic patients not undergoing cataract surgery but has not, to our knowledge, been previously used in a study like this one.We suggest that intravitreal injection at the time of cataract surgery could be carried out safely with encouraging visual outcomes in patients with diabetic foveal oedema and cataract.
