Initial experiences of cataract & lens surgery in 1269 patients in outpatient clean rooms using a portable laminar air flow device.

BACKGROUND: In 2020, routine cataract surgery was halted in most countries due to the COVID-19 pandemic in order to reduce transmission. With a consequent lack of theatre space, we developed a safe cataract pathway in outpatient department clean rooms to minimize patient exposure and time spent in hospital using a sterile laminar air flow device. We describe our initial experiences of restarting elective cataract surgery in the UK outpatient setting, outside of the operating theatre environment. METHODS: This was a prospective consecutive study of our clinical practice. A sterile air zone unit, the Toul Meditech Operio Mobile device, was used to create a sterile surgical site in three separate outpatient clean rooms from May 2020 to December 2021 in different geographical locations within Herefordshire, UK. Observations of the time spent in the department and a formal patient satisfaction survey were carried out for the initial 100 patients. All patients were followed up to assess development of post-operative complications. RESULTS: 1269 patients were included in the study. No patients sustained post-operative infection (n = 0/1269, 0%). For the initial 100 patients, the average time spent within the department was 74.3 min (unilateral cases, range 45-115 min) and 93.1 min (bilateral, 55-135 min). Patient satisfaction was high. CONCLUSION: Initial results demonstrate a safe, efficient and effective cataract surgery pathway with high patient satisfaction by converting outpatient clean rooms into ophthalmic operating theatres using the Toul Meditech Operio Mobile.

Acute Leukemia Presenting in the Pediatric Orbit.

We present a case series to evaluate the clinical features of acute leukemia presenting with primary orbital manifestations. We undertook a retrospective case review of primary orbital presentations of acute myeloid leukemia (AML) and acute lymphocytic leukemia (ALL) over a 10-year period at two hospital sites (Hereford County Hospital and Leicester Royal Infirmary). Our case series included four patients - two with AML and two with ALL. Patients were young (mean age of four years and five months) at presentation, all with unilateral disease, and presented with orbital signs. Although there was some confusion with the diagnosis at the time of referral, a suspicion of malignancy was made rapidly once ophthalmic review was initiated. All four cases were diagnosed with the assistance of peripheral blood film and bone marrow biopsy, without the need for orbital biopsy. All four cases had resolution of the orbital mass and remain disease-free.

Periocular Trichoblastoma: A Diagnostic Dilemma.

A 41-year-old woman presented with a large medial canthal lesion that extended over the midline. Excisional biopsy revealed a multinodular basaloid tumor, located within the dermis and subcutaneous fat that extended into skeletal muscle at the deep and peripheral margin. Histology was consistent with trichoblastoma. A review of the literature reveals a lack of specific and sensitive immunohistochemistry markers to establish the diagnosis of trichoblastoma. Following reconstruction, the patient has shown no signs of recurrence of the lesion at 24 months.

Montgomery in, Bolam out: are trainee surgeons 'material risks' when taking consent for cataract surgery?

Trainee involvement in cataract surgery is vital to allow proper training of the next generation of ophthalmic surgeons. However, recent changes in the UK Law, coupled with open publication of National Cataract Dataset results, lead us to conclude that the status of being a trainee is itself a material risk that now needs to be divulged to patients during the consent process. The opinions of current trainee surgeons in the UK were sampled via questionnaire and clinical negligence counsel was involved in the authorship of the paper in order to analyse the legal issues at stake. Attitudes towards consent regarding trainee involvement in UK cataract surgery need to change.

Direct eyelid defect closure: a prospective study of functional and aesthetic outcomes.

BACKGROUND/OBJECTIVES: Direct closure (DC) of eyelid defects has been retrospectively shown to give excellent outcomes. We present prospective outcome data as further evidence to promote its wider use. SUBJECTS AND METHODS: A consecutive, unselected, series of patients undergoing eyelid tumour resection was studied prospectively. DC was attempted at the time of biopsy in all of them. If DC proved impossible, delayed reconstruction using other techniques was later performed. Defect size, pre- and post-operative palpebral aperture (PA) measurements and the final visit patients' and surgeons' satisfaction scores for function and appearance were recorded. RESULTS: Seventy-three eyelids of 70 patients were studied. Mean resected specimen width was 16.4 mm (4-26 mm) in the DC group, versus 23.9 mm (11-42 mm) for other, non-DC reconstructions. Primary DC was achieved in 74% of this cohort. Mean final post-operative PA measurements in the DC group were 0.7 mm vertically (p = 0.003) and 0.8 mm horizontally (p = 0.009) less than preoperatively, but there was no statistical difference (p = 0.1) in the final horizontal measurements between the operated and un-operated sides in the DC group. DC satisfaction scores were excellent for both eyelid function and appearance. CONCLUSIONS: DC of eyelid defects, irrespective of per-operative PA distortion, gives excellent late post-operative outcomes. We recommend that DC, aligning the closure tension parallel to the lid margin, is attempted whenever wound margin approximation is possible in preference to alternative reconstruction techniques, regardless of any temporary PA distortion and globe displacement that this may cause. Eyelid function and appearance recover to near normal within 2 months.

Profound hypotony maculopathy in a first episode of bilateral idiopathic acute anterior uveitis.

BACKGROUND: We report a case of a HLA-B27 negative patient presenting with severe, bilateral, idiopathic acute anterior uveitis with acute hypotony and hypotony maculopathy as their first uveitic episode. CASE PRESENTATION: Within a week of onset of her first episode of acute anterior uveitis, a 45 year-old Caucasian lady developed profound ocular hypotony with unrecordable intraocular pressures, reduced vision and choroidal folds. All investigations were negative. Uveitic hypotony responded slowly to corticosteroids--intravenous, oral and topical--with normalization of intraocular pressure and resolution of choroidal folds after two months. Anterior uveitis and hypotony have not returned with six months of follow-up. CONCLUSION: Bilateral, profound hypotony maculopathy may present acutely in idiopathic acute anterior uveitis, may be slow to respond to treatment and should be considered as a cause of vision loss in patients with this condition.

Orbital mass secondary to acute lymphoblastic leukaemia in a child: a rare presentation.

We report the case of a 3-year-old child, who presented with lid swelling which progressed to proptosis of the left eye. He also had systemic symptoms of fatigue and weight loss. An examination revealed hepatosplenomegaly and lymph node enlargement. Investigations showed a peripheral smear with blast cells, which were also revealed through a bone marrow biopsy. A CT scan showed a mass lesion in the left orbit that had infiltrated into the surrounding tissues. He was diagnosed with acute lymphoblastic leukaemia (ALL) with left-sided orbital mass secondary to it. Haematogenous masses in the orbit are commonly due to granulocytic sarcomas, which are usually associated with acute myelogenous leukaemia (AML), not ALL, and are rare especially when they precede systemic disease.

Dacryolith-induced acute dacryocystitis: a reversible cause of nasolacrimal duct obstruction.

AIMS: To report an unusual case of acute dacryocystits with fully patent nasolacrimal duct at follow-up after incision and curettage. CASE REPORT: A 63-year-old patient with acute dacryocystitis and nasolacrimal duct abscess. CT orbits confirmed dacryocystitis without any orbital collection. Incision and drainage of the abscess was performed. RESULTS: Postoperative syringing of nasolacrimal duct demonstrated a fully patent nasolacrimal duct, with long term relief of epiphora. CONCLUSION: In some patients, dacryocystorhinostomy is not required after incision and drainage of a nasolacrimal abscess; reversible causes such as dacryoliths should always be considered.

Skin graft hypertrichosis associated with prostaglandin analog in the treatment of glaucoma.

Prostaglandin analogs are commonly used in the treatment of glaucoma. They are a safe and effective treatment associated with few side effects. Common local side effects include conjunctival hyperemia, iris pigmentation, and eyelash hypertrichosis. The authors present a case of a patient using travoprost treatment for primary open-angle glaucoma, who underwent excision of a lower eyelid basal cell carcinoma and reconstruction with an upper eyelid tarsoconjunctival flap and overlying skin graft. The patient developed hypertrichosis of the skin graft attributable to prostaglandin analog use.

Transconjunctival entropion repair - the backdoor approach.

PURPOSE: To present a modified transconjunctival approach for involutional entropion repair. METHODS: This study is a retrospective consecutive single surgeon case series using a transconjunctival approach for involutional lower lid entropion (ILLE) repair. RESULTS: Eleven eyes were operated for involution entropion with 9 cases of complete resolution. Two patients required further Jones' retractor plication. CONCLUSION: Transconjunctival involutional lower lid entropion repair is a time-efficient, safe, and efficacious technique. The scar free technique described leads to full restoration of lower lid anatomy. In contrast to other reports we found a relatively low rate of recurrence on follow-up.

Acute suppurative bacterial dacryoadenitis: a case series.

BACKGROUND: We present a series of patients with acute suppurative bacterial dacryoadenitis and review the clinical presentation, microbiology, treatment options and outcome. METHODS: A multicentre, retrospective, case series review of patients with a clinical diagnosis of acute bacterial suppurative dacryoadenitis (ASBD). Records were examined to obtain information regarding patient demographics, presenting symptoms and signs, radiology, microbiology, management, outcomes and follow-up. RESULTS: 11 patients (9 men, 2 women; mean age 43.9 years, range: 6-82 years) were included. Average time to presentation was 2.8 days, and predisposing conditions were found in 45% of cases. Common presenting symptoms were eyelid swelling, pain, redness and diplopia, and common signs were ptosis, discharge and restriction of eye movements. The most common causative bacteria were Staphylococcus aureus and skin flora. Lacrimal gland swelling was universally seen on CT, with globe indentation of displacement in 27% of cases. Intravenous antibiotics were used in 91% of cases, which subsequently resolved over an average period of 9.7 days. Those with abscess formation (n=2) required incision and drainage. CONCLUSIONS: ASBD is a rare condition that resolves quickly if managed appropriately. Underlying anatomical, infectious or inflammatory conditions should be investigated, and skin commensals should be covered with the instigation of antibiotic therapy.

Neuro-ophthalmology of invasive fungal sinusitis: 14 consecutive patients and a review of the literature.

BACKGROUND: Invasive fungal sinusitis is a rare condition that usually occurs in immunocompromised patients and often presents as an orbital apex syndrome. It is frequently misdiagnosed on presentation and is almost always lethal without early treatment. DESIGN: Retrospective case series of 14 consecutive patients with biopsy-proven invasive fungal sinusitis from four tertiary hospitals. PARTICIPANTS: Fourteen patients (10 men and 4 women; age range 46-82 years). METHODS: Retrospective chart review of all patients presenting with invasive fungal sinusitis between 1994 and 2010 at each hospital, with a close analysis of the tempo of the disease to identify any potential window of opportunity for treatment. MAIN OUTCOME MEASURES: Demographic data, background medical history (including predisposing factors), symptoms, signs, radiological findings, histopathological findings, treatment approach and subsequent clinical course were recorded and analysed. RESULTS: Only one patient was correctly diagnosed at presentation. Only two patients were not diabetic or immunocompromised. The tempo was acute in two patients, subacute in nine patients and chronic in three patients. In the subacute and chronic cases, there was about 1 week of opportunity for treatment, from the time there was a complete orbital apex syndrome, and still a chance for saving the patient, to the time there was central nervous system invasion, which was invariably fatal. Only two patients survived - both had orbital exenteration, as well as antifungal drug treatment. CONCLUSIONS: Invasive fungal sinusitis can, rarely, occur in healthy individuals and should be suspected as a possible cause of a progressive orbital apex syndrome.

Lacrimal duct cyst (dacryops) following ocular chemical injury.

A 37-year-old man presented with swelling under the lateral aspect of the right upper eyelid. He had sustained an alkali ocular chemical injury 10 years before resulting in persistent lateral canthal webbing. Diagnosis was made of lacrimal duct cyst (dacryops) and webbing of the lateral canthus and the findings were confirmed on computed tomography. He underwent lacrimal duct cyst marsupialisation and lateral canthoplasty with good cosmetic result, and there was no recurrence of symptoms at 2 months post-operatively. Lacrimal duct cyst is a rare clinical entity and has been postulated to result from localized inflammation or trauma to conjunctiva. To the best of our knowledge, this is the first report of dacryops following a chemical injury.

Acute dacryocystitis associated with epstein-barr virus infection.

Acute dacryocystitis is a rare complication of infectious mononucleosis with only three previous reports in the English literature. We present two further children with acute dacryocystitis and clinical and laboratory features of Epstein-Barr Virus related infectious mononucleosis. Both were treated with systemic antibiotics and one child additionally required surgical drainage of a lacrimal sac abscess. Both children made a complete recovery without any lacrimal symptoms. Acute dacryocystitis is uncommon in children without a history of congenital nasolacrimal duct obstruction, and an underlying systemic condition such as infectious mononucleosis should be suspected. In such patients, dacryocystitis can be expected to resolve without symptoms of nasolacrimal duct obstruction and dacryocystorhinostomy is seldom required.

Acute Charles Bonnet syndrome secondary to eye patching.

OBJECTIVE: The aim of this study was to report a case of Charles Bonnet syndrome secondary to eye patching following eyelid reconstruction with an unusually acute onset. METHOD: An observational case report was conducted. RESULTS: The patient reported complex visual hallucinations that started less than 10 minutes after patching of her right eye (the left eye had poor vision from previous trauma). The patch was removed after 2 days, and the hallucinations gradually stopped over the subsequent 2 days. CONCLUSION: This case of Charles Bonnet syndrome describes an unusually acute onset of hallucinations and is only the second reported case following eye patching. Eye patching is commonly used in a number of situations, and it is important to be aware of this association, as the diagnosis of Charles Bonnet syndrome is often overlooked.

Endoscopic dacryocystorhinostomy in acute dacryocystitis: a multicenter case series.

OBJECTIVE: To present our experience of early endonasal DCR (endoDCR) in the treatment of acute dacryocystitis (AD). Methods. International multicenter non-comparative retrospective study. RESULTS: Eighteen patients were identified. All were treated with antibiotics prior to surgery with a median of time from referral to endoDCR surgeon to surgery of 3 days (range 1-7). Surgery was performed using mechanical powered endoDCR (MENDCR) in 15/18 (83.3%) cases; mitomycin C was used in 5/18 (27.8%) and all cases underwent bicanalicular intubation. An increase in perioperative bleeding was noted in 5/18 (27.8%), causing interference in surgical technique in one (5.6%). Resolution of AD was seen in all cases, with no recurrences. 17/18 (94.4%) cases were free of epiphora at median follow-up of 12 months (range 2-36), with nasal endoscopy revealing free flow of fluorescein through the ostium in 17/18 (94.4%) of cases. The median total length of stay was 1 night (range 0-3). CONCLUSIONS: EndoDCR surgery performed early in AD led to rapid resolution of the condition in all cases and was associated with subsequent anatomical and functional success in 94.4% of cases. Early endoDCR surgery in the context of AD and the potential associated health economic benefits are worth further consideration and study.

Composite grafts in eyelid reconstruction: the complications and outcomes.

AIMS: To describe the outcomes and complications for composite eyelid grafts in a large case series over a 9-year period. METHOD: A retrospective study of all patients who underwent a composite graft for eyelid reconstruction between January 2000 and May 2009. A composite eyelid graft involves the excision of a full thickness pentagonal wedge from the donor eyelid, which is inserted into the recipient eyelid defect. The orbicularis muscle is discarded from the composite graft. Initial diagnosis, complications, postoperative eyelid contour and colour were recorded. RESULTS: Forty-two patients were identified in the study period; the mean age was 69 years. Reconstruction following basal cell carcinoma excision was the commonest indication for surgery. Thirty-five composite grafts were performed for lower eyelid defects and seven for upper lid defects. The average size of the grafts was 9.1 (range 7-12) mm. Five patients required two grafts to reconstruct the defect. Thirty-six (86%) patients achieved a satisfactory contour and 33 (78%) patients had good matching skin colour. Partial dehiscence occurred in five patients and three patients had bulkiness of the graft postoperatively. We had no episodes of graft failure, although two patients had skin necrosis, which resolved. CONCLUSION: Composite eyelid grafts when combined with mobilisation of the recipient orbicularis muscle can result in good preservation of eyelid function with satisfactory cosmesis.
