Abstract
INTRODUCTION Self-inflicted enucleation, also known as auto-enucleation (AE) or Oedipism, is an uncommon and severe form of ocular injury which presents as an ophthalmic and psychiatric emergency. Usually known to occur with untreated psychosis, this case is a rare report which demonstrates AE as a result of a subsequently diagnosed drug induced psychosis. We report the clinical presentation, management and for the first time a detailed speculative account about the mechanism of AE, based on our clinicopathologic findings. CASE REPORT A 53-year old Afro-Caribbean patient was arrested following an altercation and was incarcerated awaiting arraignment. The patient had no previous psychiatric history but tested positive for cannabis, opiates and cocaine as well as admitting to illicit drug use in the community. Whilst in custody, the patient self-enucleated his right eye. The patient declined consent to eye examination and was subsequently admitted under section 2 of the Mental Health Act. After full work-up including Goldmann visual fields and magnetic resonance imaging, he underwent right orbital exploration under anesthetic where AE was confirmed whilst the left eye showed evidence of attempted enucleation. The residual tenons and conjunctiva was subsequently repaired without placement of an orbital implant in the right orbit. The globe was sent for histology which revealed clues to the potential mechanism of auto-enucleation. CONCLUSION This case is unique as it offers an alternative presentation to those most commonly reported in the current literature, highlights the sparsity of literature detailing the mechanism of AE and stimulates discussion around various potential systemic etiological differential diagnoses, management strategies and complications of AE.

Squamous cell carcinoma in the anophthalmic socket: a series of four cases with HPV-16 profiling. Br J Ophthalmol 2018; 103:bjophthalmol-2018-311916. [PMID: 29954784 DOI: 10.1136/bjophthalmol-2018-311916] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/08/2018] [Revised: 05/10/2018] [Accepted: 06/11/2018] [Indexed: 01/24/2023]
Abstract
PURPOSE To present the clinical and histological features of squamous cell carcinoma (SCC) in the anophthalmic socket in four adult patients, and to determine the presence of human papillomavirus infection (HPV). METHODS Retrospective case series of four adult patients with SCC of the anophthalmic socket. P16 immunohistochemistry and HPV testing was carried out in all cases. The authors report clinical findings, histopathology, management and outcomes for all four patients with conjunctival SCC. Previously reported cases of conjunctival SCC in anophthalmic sockets were reviewed. RESULTS Four adult patients presented with eyelid lumps, discharge or change in prosthesis fit. Common examination findings included papillomatous changes, eyelid masses and epithelial changes. Three out of the four cases (75%) were positive for p16 by immunohistochemistry and the same cases positive for HPV-16 DNA. All patients received cryotherapy, topical or intralesional chemotherapy. Two patients proceeded to exenteration for control of invasive disease. CONCLUSIONS To the authors' knowledge, this is the largest series of SCC in the anophthalmic socket with comprehensive annotation of HPV status. Although socket conjunctiva is protected from environmental radiation, there is still a risk of neoplastic transformation in this tissue, thus patient education and regular checking of sockets by ophthalmologists should be undertaken as a preventative measure. The potential role of HPV in these tumours warrants further investigation.

Abstract
Purpose The purpose of this study was to assess indications and outcome of carotid Doppler ultrasound requested by ophthalmologists from an eye hospital over a period of three years. METHODS This retrospective study was designed to analyse data for all patients referred to have carotid Doppler ultrasound from 1999 to 2001. Colour fundus photograph was used to ascertain diagnosis of ocular condition. Detailed case note analysis was done to correlate patient details, indication, results of carotid Doppler, and status of anti-platelet treatment as well as presence of other risk factors. Results 107 patients were included in the study. 46.7% had normal internal carotid on Doppler while 53.3% patients had stenosis, 22.8% of which were significant. 15 out of 24 patients with retinal artery occlusion had internal carotid artery (ICA) stenosis. 2 out of 6 patients with migraine had significant stenosis. 12 patients had retinal vein occlusion (5 were bilateral), 9 of whom showed ICA stenosis. 14 of 15 patients with retinal emboli had stenosis of ICA. Other diagnoses included anterior ischaemic optic neuropathy, cranial nerve palsy, etc. 42 patients had 1 to 3 risk factors, and 11 patients had more than 3 risk factors. Ophthalmologists started anti-platelet management in 24 patients (42.1%) with some degree of ICA stenosis. CONCLUSIONS Approximately 55% of our patients referred for carotid Doppler were positive for ICA stenosis with nearly a fifth of such referrals having more than 70% stenosis, which is considered to be clinically significant. Our results highlight the importance of such referrals for carotid Doppler for various ophthalmic conditions by the ophthalmologists.

Abstract
PurposeTo highlight the clinical and surgical considerations in treating patients with apparent recurrent acute dacryocystitis with a patent lacrimal system.MethodsThree children referred to a tertiary unit as recurrent acute dacryocystitis were reviewed retrospectively. Imaging and subsequent surgical intervention revealed the underlying diagnosis.ResultsAll three cases presented with recurrent abscesses in the region of the lacrimal sac that failed to respond to incision and drainage. The lesions were lower and more lateral to the usual location of a sac abscess and closer to the inferior orbital rim. All three cases were found to have patent lacrimal systems on syringing, and all were found to have infected, low-lying, anteriorly placed aberrant ethmoid air cells on computed tomography and magnetic resonance imaging. These were confirmed on subsequent surgical exploration.ConclusionsInfected low-lying ethmoid air cells can mimic dacryocystitis with recurrent abcesses. In cases where a patent nasolacrimal system is demonstrated and a more inferolateral location of the swelling than would be expected in dacryocystitis is seen, imaging is warranted to ensure the appropriate intervention is undertaken. Anterior ethmoidectomy as opposed to dacryocystorhinostomy is the appropriate treatment in these cases.

Abstract
IgG4-related orbital disease is a recognised cause for orbital inflammation. As its awareness increases and diagnostic accuracy improves there will be an increased number of cases being identified. This unique case demonstrates for the first time, with histological evidence, a case of a non-lacrimal IgG4-related orbital disease with concurrent IgG4-related mastitis. We describe a 47 year old who presented with a supraorbital swelling and mass. This was initially successfully treated with oral steroids and was later excised on recurrence. Immunohistochemical and blood serum analysis confirmed IgG4-related orbital disease. On systemic enquiry she was found to have a mass of the breast, which was shown to be IgG4-related mastitis. She is currently asymptomatic with no sign of recurrence and is under long-term surveillance. This case highlights the importance of systemic work up in patients presenting with orbital foci of IgG4 disease.

Abstract
New-onset Graves' ophthalmopathy (GO) following radioiodine treatment (RAI) and worsening of existing GO are well-described in the endocrinology literature. These phenomena are recognized by ophthalmologists, yet poorly documented in the ophthalmology literature. Two male patients, aged 43 and 62 years, respectively, with Graves' disease without GO, received RAI. Four months later, one patient developed acute GO with unilateral reduction in visual acuity, conjunctival chemosis, lagophthalmos, bilateral severely restricted ocular motility, and lid retraction. High-dose intravenous steroids, followed by oral steroids, led to a dramatic clinical improvement. The second patient received a second dose of RAI for persistent hyperthyroidism and subsequently developed acute GO-comprising restricted ocular motility, peri-orbital swelling, and conjunctival chemosis. Symptoms gradually resolved on continued carbimazole treatment. Neither patient received pre-RAI prophylactic glucocorticoids, as currently they are only recommended for patients with pre-existing GO or multiple risk factors. We discuss the limitations of using this risk-based approach in preventing new-onset GO following RAI therapy.

Abstract
PURPOSE The primary objective of the study was to determine the incidence of the various pathological conditions present at the base of the periocular cutaneous horns. The secondary objective was to study the presentation of these cutaneous horns with a view to finding any clinical indicators for premalignant, malignant and benign lesions at the base. METHODS Prospective multicentre study of patients presenting with cutaneous horns. Informed consent followed by excision biopsy of the base lesion was performed in all the cases included for the study. The biopsy specimens were examined histologically and results analysed. RESULTS Twenty-six patients presented with cutaneous horns in the periocular region over a period of 2 years, of these two patients presented with more than one cutaneous horn. 23 patients underwent excision biopsy. There were a total of 25 specimens. Of the base lesions 2/25 (8%) were malignant, 7/25 (28%) were pre-malignant and the remaining 16/25 (64%) were benign. Analysis of the findings on clinical presentation revealed no clinical indicators to correlate with the final histology. CONCLUSION The incidence of malignant and pre-malignant lesions present at the base of periocular cutaneous horns was 36% with 8% of them being malignant. It is important to perform an excision biopsy with histological diagnosis of the base of the cutaneous horn as there are no definite clinical features that point towards a potential for malignancy.

Abstract
PURPOSE To describe ocular findings in patients with established obstructive sleep apnoea hypopnoea syndrome (OSAHS) using continuous positive airway pressure (CPAP). METHODS hundred and fifteen referrals investigated for OSAHS were included. Patients with OSAHS were compared with those with normal sleep study controls. Subgroup analysis for CPAP users and non-users was also carried out. RESULTS OSAHS patients (n=89) compared with the controls (n=26) had higher ocular irritation symptoms (P<0.001), abnormal tear break-up time (P<0.05) with increased upper (P<0.001) and lower (P<0.001) lid laxity. Floppy eyelid syndrome (FES) was noted in 31.5% (28/89) OSAHS patients vs 3.8% (1/26) controls (P=0.005). Open angle glaucoma prevalence in OSAHS patients (3/89, 3.4%) was similar to the controls (1/26, 3.8%) (P=0.92). Sixty-seven (75.3%) OSAHS patients were using CPAP (average duration: 19.6+/-15.3 months). All CPAP users maintained a supine sleep posture to prevent mask edge leaks. A fifth of CPAP users (14/67) had experienced earlier episodes of conjunctivitis secondary to leaks. CPAP users had similar upper and lower lid laxity (P=0.746 and 0.633) to non-CPAP users, but a better tear film (P=0.029) and less ocular irritation (P=0.134). CONCLUSION OSAHS patients showed increased ocular irritation, abnormal tear film, lid laxity, and FES. The prevalence of glaucoma in our series was similar to normal population data of 2%, P=0.429, and may relate to use of CPAP in majority of the patients. More stable tear film in CPAP users was probably secondary to the supine sleep postures necessarily adopted with CPAP use.

Abstract
This report describes an unusual case of a 9-year-old boy with a 6-month history of right lower eyelid lesion and excoriation of the adjoining skin that had not responded to topical treatment. The umbilicated lesion was electively excised and the base of the lesion was cauterized under general anesthesia, which resulted in complete resolution of the periocular dermatitis without additional treatment. It is important to consider molluscum contagiosum in the differential diagnosis in patients with periocular dermatitis, especially in the presence of an umbilicated vesicle, although it is classically taught that these lesions present with toxic conjunctivitis.

Abstract
PURPOSE To histopathologically assess the extent and pattern of vascularization of explanted porous polyethylene (PP) and hyrdoxyapatite (HA) orbital implants. To compare the vascularization in PP implants harvested after enucleation versus after evisceration. METHODS This is a comparative case series of six orbital implants explanted between 11 months and 5 years and 4 months post implantation. The implants were subjected to histopathological examination with various stains, after complete decalcification. RESULTS There were 2 post evisceration, 3 post enucleation and 1 secondary implant. The size of the implants varied from 18 to 23 mm diameter. The reason for explantation was exposure in all the 6 cases with additional infection in 2 cases. Histopathology revealed complete vascularization up to the core of the implant in all the cases. There was evidence of chronic inflammation within all the explanted specimens. Acute inflammation was present at the site of exposure in four of the implants. Three of these implants had additional evidence of necrosis. Two cases with clinically evident infection had Gram positive cocci within the implant. Foreign-body type giant-cells, melanophages and haemosiderin laden macrophages were also observed. Eviscerated specimens showed scleral remodelling and thickening. CONCLUSION All the implants were vascularized up to the core. There was histologic evidence of chronic inflammation in all the explanted implants possibly indicating the foreign nature of the implant material. The sclera did not impede vascularization of the implants in eviscerated specimens. We found no difference in the degree of vascularization of the implant in enucleated versus eviscerated implants.

Abstract
PURPOSE To evaluate the usefulness of silicone hydrogel soft contact lenses in upper eyelid procedures. METHODS Thirteen patients (14 eyes) who had full thickness upper lid reconstruction were studied. PureVision contact lenses were placed on the eyes at the commencement of the surgery. To evaluate the effectiveness of soft contact lens use, we looked at comfort, conjunctival injection, chemosis, corneal abrasion, lid oedema, evidence of infection and speed of healing. RESULTS Nine eyes (64.29 per cent) were entirely asymptomatic. Three eyes developed corneal abrasions and changing the contact lenses led to resolution of the symptoms. One eye developed cloudy vision at one week due to accumulation of discharge behind the contact lens and another eye had foreign body sensation. Both had immediate relief with contact lenses removal. Mean duration of contact lens wear was 19.5 days (range, seven to 35 days). There were no cases of chemosis, infection, unexplained post-operative inflammation or delayed wound healing. CONCLUSIONS Despite its limitations, our study suggests that a soft contact lens may be a useful option in upper lid surgery.

Abstract
PURPOSE To demonstrate the potential for the use of AlloDerm as a posterior lamellar graft in the reconstruction of full-thickness lid defects. METHOD In our case series, we evaluated the surgical outcome of three consecutive patients, two with an upper eyelid defect and one with a lower eyelid defect who underwent lid reconstruction using AlloDerm grafts. RESULTS AlloDerm was readily taken up into the wound defect, with complete coverage of its bulbar surface by conjunctiva. In all the cases, the cornea was not affected by its contact to the AlloDerm. A mucocutaneous junction formed over the margin of the AlloDerm graft with good cosmesis. CONCLUSION AlloDerm has the potential to act as an effective posterior lamellar substitute in situations where there is an adequate amount of skin muscle cover available to drape over it. It is rigid enough to replace tarsus and its structure behaves as a scaffold allowing conjunctiva to readily grow over it.

Abstract
PURPOSE To evaluate the results of the porous polyethylene (Medpor) orbital implantation technique combined with the use of a primary patch graft of acellular dermis. METHODS The study design was a retrospective, non-comparative single surgeon case series of 27 patients. The Medpor orbital implant was placed with a primary anterior sub-Tenon's acellular dermis patch after evisceration (23/27), enucleation (2/27) or implant exchange/secondary implant procedure (2/27) over a period of 3 years. Risk factors for dehiscence/complications were defined as trauma, infection, inflammation, previous ocular surgery, radiotherapy, secondary orbital implantation, and removal of extruding implants. The primary outcome measure was the development of implant exposure. Other complications were also recorded, including postoperative conjunctival wound dehiscence. RESULTS Twenty-five patients (93%) had more than 2 risk factors. Mean follow-up time was 22 months (median 24 months, range 4-34 months). Three (11%) patients needed further intervention, which included pyogenic granuloma excision (1) and fornix formation (1). Conjunctival wound dehiscence followed by implant exposure occurred in 1 of 27 eyes (3.7%). The cosmetic appearance was satisfactory in 26/27 patients. CONCLUSIONS Our results with primary acellular dermis grafts when coupled with Medpor orbital implantation are encouraging.

Abstract
PURPOSE To determine the prevalence of patients taking tamsulosin and the appearance of intraoperative floppy-iris syndrome (IFIS) and associated cataract surgery complications. SETTING District general eye unit with 10 consultants in West Midlands, England, United Kingdom. METHODS This nonrandomized observational prospective study identified patients on tamsulosin from the preoperative assessment for cataract surgery performed between March and August 2005. A questionnaire on the presence of IFIS and related intraoperative complications was attached to the patients' records and answered on the day of surgery. RESULTS Of the 2390 cataract procedures performed, 15 patients (17 eyes) were taking tamsulosin. Five eyes (30%) displayed all 3 characteristics of IFIS, 6 (35%) displayed some of the characteristics, and 6 (35%) did not display any IFIS feature. Adjustment in the surgical technique was necessary in 2 eyes. One case had zonular dehiscence. CONCLUSIONS The prevalence of tamsulosin intake was lower in this study's English population than that reported in the U.S. literature. The duration of tamsulosin intake did not appear to correlate with the severity of IFIS, and the overall complication rate was low.

Abstract
AIM To study the overall level of evidence-based practice in an accident and emergency eye unit in the UK and evaluate the extent of evidence-based practice by ophthalmologists and nurse practitioners (NPs). METHODS The case notes of all new patients attending our accident and emergency department for a period of 1 week were reviewed prospectively. For each case, the diagnosis at presentation and its intervention was ascertained. A literature search using Medline and Cochrane library was performed to assess the level of evidence provided for each diagnosis-intervention pair. Each diagnosis-intervention pair was evaluated and graded to assess the best level of evidence provided. RESULTS A total of 474 new patients attended the eye casualty during the study period. No diagnosis was made in 27 cases and they were excluded from the analysis. Out of 447 patients, 308 (68.9%) cases were managed by NPs and 139 (31.1%) by doctors. A total of 294 (65.8%) patient interventions were based on evidence from systematic reviews, meta-analysis and randomised-controlled trials, of which 223 were managed by NPs and 71 by ophthalmologists. This difference was statistically significant with P<0.001. One hundred and seven (23.9%) interventions were supported by evidence from prospective and retrospective trials. CONCLUSION This study demonstrated that two-thirds of interventions were based on the highest level of evidence and was comparable to studies performed in other specialities. It also highlights the advanced role of trained NPs in acute ophthalmology.

AIM To study the feasibility of a modified fast-track protocol for periocular basal cell carcinoma (BCC). METHODS A modified protocol was set up with an aim to examine all periocular BCCs within 6 weeks of referral to our oculoplastic clinic. An audit of this protocol was performed over a 2-year period. RESULTS A total of 65 patients were referred as a 'possible BCC' over the 2-year period. In all, 32 of these patients were referred by dermatologists (49%), followed by fellow consultant ophthalmologists (20 patients, 31%) and general practitioners (11 patients, 17%). The clinical suspicion in the oculoplastic clinic agreed with the referral diagnosis in 71% (46 of the 65) of patients. This figure was particularly high for referrals from dermatologists (84%). In all, 44 out of the 46 'clinically suspected BCC' underwent surgical excision. Histopathology confirmed BCC in 39 of these 44 patients, a diagnostic accuracy of 89%. Among the subgroup of patients referred by the dermatologists, the largest source of referrals, 24 out of 30 patients that underwent surgical excision had histologically proven BCC; a diagnostic accuracy of 80%. CONCLUSION Our study shows that the modified fast-track protocol for periocular BCCs is practical and feasible. Such a practice is highly desirable since it prevents a long wait for patients who are aware of a possible malignant periocular lesion.

Abstract
PURPOSE The aims of ideal preoperative informed consent include educating the patient adequately to enable an autonomous decision to be made without causing undue anxiety. We study how the paternalistic and nonpaternalistic approaches meet this ideal. The influence of the new patient consent forms is also assessed. METHODS Two cycles of a prospective clinical audit are presented. An assessment of relevant patient knowledge was performed by patient interview. Visual analogue scales were used to quantify patient anxiety. RESULTS The first cycle, examining a paternalistic approach, demonstrated: 37% of patients understood what a cataract was and 48% understood what surgery involved. 48% misunderstood that cataract surgery was completely risk free. In total, 80% of patients undergoing second eye surgery believed that it was completely risk-free. Average anxiety visual analogue scores (VAS) for cataract surgery were low (2.89). The second cycle, examining the nonpaternalistic approach combined with the implementation of new consent forms showed that, despite more explicit repeated preoperative consent: 39% of patients understood correctly what a cataract was, 28% understood what surgery involved and 43% misunderstood that surgery was completely risk-free. All patients undergoing second eye surgery thought that it was risk-free. The average anxiety VAS for cataract surgery were moderate (5.00). CONCLUSIONS Both paternalistic and non-paternalistic approaches to informed consent are inadequate in meeting the demands of the ideal informed consent. The new patient consent forms appear to have little effect in influencing patient knowledge about their surgery. Patients undergoing second eye surgery often have an overoptimistic view of cataract surgery.

Abstract
AIM To identify the relative incidence and profile of adverse drug reaction (ADR) to various topical ocular hypotensives in a hospital setting. METHODS All the patients presenting in outpatients clinic and accident and emergency with an ADR to topical hypotensive agent from August 2000 to January 2001 were included in the study. Details regarding the type date of commencing the treatment, the date of developing ADR, time to resolution of the ADR were noted. RESULTS Over the period of 6 months, 66 patients presented with 73 ADRs. Brimonidine was the most frequent offending agent. In total, 23 (34.8%) presented with ADR after being commenced on treatment for more than 12 months. In all, 16 (24%) patients had IOP > 21 on presentation, eight (12%) patients underwent filtration surgery following the development of ADR. CONCLUSION Adverse drug reaction to ocular hypotensive agents is not uncommon and can have a major impact on glaucoma management. Delayed presentation and association with raised intraocular pressure presentation emphasise the need for effective patient education to encourage prompt reporting of ADR.

Abstract
PURPOSE The purpose of this study was to assess indications and outcome of carotid Doppler ultrasound requested by ophthalmologists from an eye hospital over a period of three years. METHODS This retrospective study was designed to analyse data for all patients referred to have carotid Doppler ultrasound from 1999 to 2001. Colour fundus photograph was used to ascertain diagnosis of ocular condition. Detailed case note analysis was done to correlate patient details, indication, results of carotid Doppler, and status of anti-platelet treatment as well as presence of other risk factors. RESULTS 107 patients were included in the study. 46.7% had normal internal carotid on Doppler while 53.3% patients had stenosis, 22.8% of which were significant. 15 out of 24 patients with retinal artery occlusion had internal carotid artery (ICA) stenosis. 2 out of 6 patients with migraine had significant stenosis. 12 patients had retinal vein occlusion (5 were bilateral), 9 of whom showed ICA stenosis. 14 of 15 patients with retinal emboli had stenosis of ICA. Other diagnoses included anterior ischaemic optic neuropathy, cranial nerve palsy, etc. 42 patients had 1 to 3 risk factors, and 11 patients had more than 3 risk factors. Ophthalmologists started anti-platelet management in 24 patients (42.1%) with some degree of ICA stenosis. CONCLUSIONS Approximately 55% of our patients referred for carotid Doppler were positive for ICA stenosis with nearly a fifth of such referrals having more than 70% stenosis, which is considered to be clinically significant. Our results highlight the importance of such referrals for carotid Doppler for various ophthalmic conditions by the ophthalmologists.

Abstract
PURPOSE To review the long-term outcome following surgical treatment for canaliculitis. METHODS All cases of canaliculitis treated surgically from January 1995 to December 2001 were identified from theatre records. Case notes were reviewed retrospectively looking specifically for delay in diagnosis (defined as two or more visits prior to diagnosis), culture results and outcome following surgical treatment. Telephonic questionnaires were used to assess the incidence of post-treatment epiphora. Symptomatic patients were offered clinic appointments for further assessment and management. RESULTS Fifteen eyes of 15 patients were identified, 13 were females and 2 males. Mean age was 69.6 years (range 45-87 years). One patient had both upper and lower canaliculitis. The remaining 14 (93.3%) had lower canaliculitis. Diagnosis was delayed in 7 of the 15 patients (46.6%). Culture results were positive in 66.6% with Staphylocococcus spp. being the most common isolate (26.6%). Actinomyces was isolated in only 2 of the 15 cases (13.3%). Conservative treatment had been tried in 5 cases (33.3%). All patients had resolution of symptoms following canaliculotomy. Epiphora was identified in four of the treated eyes on telephonic questionnaires. Of these, three eyes had preexisting lacrimal pathology. Average follow-up was 26 months (range 6-83 months). CONCLUSION Canaliculotomy is safe and efficacious in the treatment of lacrimal canaliculitis with no demonstrable risk of posttreatment epiphora.

Abstract
PURPOSE To determine the accuracy of the clinical diagnosis of benign eyelid skin lesions in a minor operation theatre (MOT) setting. METHODS This study was carried out prospectively over a 6-month period. Subjects attending the minor operation theatre set-up with eyelid skin lesions were assessed and lesions were labelled as benign, pre-malignant or malignant. All patients underwent excision biopsy of the lesion. Histopathologic diagnosis was obtained for each lesion, which was then matched with the respective clinical diagnosis. The Diagnostic Accuracy (DA) was calculated for benign lesions using the formula proposed by Lightstone et al. RESULTS Two hundred eyelid skin lesions from 183 consecutive patients were included in the study. Clinically, 187 lesions were labelled as benign, 12 as malignant and 1 as pre-malignant. The histopathologic report matched with the clinical diagnosis in 192 cases (96%). However, incorrect diagnoses included 3 malignant and 3 pre-malignant lesions that were labelled as benign clinically. The DA for benign lesion was 95.7%. CONCLUSION Histopathologic confirmation may be necessary for most cases in the MOT.

Abstract
AIM The purpose of this study was to investigate the hitherto undescribed effects of botulinum toxin A injected into the lacrimal gland in patients with functional epiphora. METHODS A prospective non-comparative interventional case series study was designed to include patients with functional epiphora who presented to the Oculoplastic unit at the Wolverhampton and Midland Counties Eye Infirmary. Botulinum toxin A (2.5-5 units) was injected into the palpebral lobe of the lacrimal gland on the worst affected side via a transconjunctival approach under topical anaesthesia. Patients underwent a Schirmer test and provided a subjective evaluation of their epiphora symptoms, indoors and outdoors, at baseline and at 1, 4 and 13 weeks after injection. The mean score for symptoms indoors and outdoors was calculated. RESULTS Fourteen patients agreed to take part in the study. Subjective epiphora scores improved in 8 out of the 11 patients (72.7%) who completed 13 weeks of follow-up. Schirmer test results showed objective reduction in tearing from baseline but did not strongly correlate with the subjective epiphora scores. Transient mild ptosis and diplopia were experienced by two patients. CONCLUSION The results from this small pilot study are encouraging, although larger, controlled trials are needed to assess the optimal dose of BTX-A, its long-term efficacy and safety, and the role of multiple injections.

Abstract
BACKGROUND Pain from local anaesthetic injection for minor eyelid surgery can often be severe enough to be the most unpleasant part of the procedure. This study was aimed at assessing the efficacy of 50 : 50 N(2)O/O( 2) (Entonox) in relieving such pain. METHODS In this randomised placebo-controlled double blind trial, 100 patients were randomised to receive either Entonox or air. Questions regarding pain during the administration of local anaesthetic, discomfort during the procedure and side effects experienced were asked by an investigator who was blinded to the type of gas inhaled. RESULTS The difference in pain score between the Entonox and control groups was not statistically significant (p = 0.474). The difference in discomfort score between the two groups was also not statistically significant (p = 0.948). More side effects were noted with Entonox than with air (p = 0.003, statistically significant). However, this was not clinically significant. CONCLUSION Entonox has been used effectively in different specialties for pain relief. However, our study was unable to show this beneficial effect in relieving pain from local anaesthetic injections for minor eyelid surgery.

Abstract
OBJECTIVE To describe a case of leukoplakia and underlying intraepithelial squamous cell neoplasia of the palpebral conjunctiva presenting in a patient wearing an ocular prosthesis. METHODS The clinical presentation, histopathological findings and surgical outcome are described in a 62-year-old man in whom leukoplakic lesions of the palpebral conjunctiva in a socket fitted with an ocular prosthesis were noted in addition to squamous cell carcinoma of the lower lid skin. RESULTS Histopathological examination revealed islands of squamous cell carcinoma in the skin lesion and squamous cell carcinoma-in-situ in the leukoplakic conjunctival specimen. Successful tumour excision and lid reconstruction were performed. CONCLUSION This report highlights the successful treatment of long-standing conjunctival squamous cell carcinoma-in-situ associated with an ocular prosthesis and a general tendency to pre-neoplastic lesions of the skin. Regular examination of the sockets of patients wearing long-standing ocular prostheses is recommended.

The association between the oculocardiac reflex and post-operative vomiting in children undergoing strabismus surgery. Eye (Lond) 1998; 12 ( Pt 2):193-6.

Abstract
The oculocardiac reflex (OCR) is a potentially serious complication of ophthalmic surgery which is most commonly elicited during paediatric strabismus surgery. Post-operative vomiting (POV) is also extremely common after such procedures and may result in admission following planned day-case surgery. Although many factors play a part in the occurrence of POV, stimulation of the trigemino-vagal reflex arc is thought to explain the particularly high rate of vomiting after strabismus surgery. The OCR and the vaso-vagal response share this neuronal pathway, the bradycardia of the OCR often being the only objective feature of the vaso-vagal response while the patient is anaesthetised. The aim of this study was to investigate the possible association between the occurrence of the OCR and subsequent POV in children undergoing strabismus surgery. We have studied this relationship in 79 children, aged between 1 and 13 years, undergoing strabismus surgery under standardised anaesthetic conditions. A positive OCR was regarded as a drop in heart rate of 10% or more, or the onset of a dysrhythmia. An intraoperative OCR was elicited in 51 (64.6%) of the 79 children, whilst 29 (36.7%) developed POV in the subsequent 24 h period. There was a significant association between a positive intraoperative OCR and POV (p = 0.01): children with a positive OCR were 2.6 times more likely to vomit than those without the reflex. We conclude that there is an association between the occurrence of the OCR and POV and discuss possible preventive strategies.
