ABSTRACT

PURPOSE: To determine the degree of static eyelid asymmetry required to be perceptible and whether this is affected by image inversion. METHODS: Images of 3 volunteers were digitally manipulated to have eyelid asymmetry of 0.5 mm, 1 mm, or 1.5 mm of 3 different types, upper lid ptosis, upper lid retraction, and lower lid retraction. Forty-nine laypersons stated whether the images were symmetrical or asymmetrical. A separate inversion survey, completed by 29 clinicians, consisted of symmetrical images and 1 mm asymmetrical images, with half being inverted. RESULTS: Upper lid ptosis, upper lid retraction, and lower lid retraction were not detected by most laypeople at 0.5 mm of severity (18.9%, 6.7%, 18.9% detection, respectively) but all 3 were detected by the majority of participants once asymmetry reached 1 mm severity (65.7%, 61.8%, 51.0% detection, respectively) and rose to over 70% identification at 1.5 mm (92.2%, 73.5%, 73.5% detection, respectively). Inversion of the images led to 19.7% lower rates of correct identification of asymmetrical faces compared with images presented in the correct orientation (80.7% asymmetry identified in normal images, 61.0% inverted, p < 0.001). CONCLUSIONS: All asymmetries were detectable by a majority of laypersons at a severity of 1 mm. Image inversion decreases a clinician's ability to detect a 1 mm asymmetry, indicating an impaired asymmetry perception in the intraoperative view. This study provides research to counsel patients with varying degrees of eyelid asymmetry.

ABSTRACT

Orbital trauma involving high-pressure grease guns is rare and can cause significant morbidity due to retained intraorbital grease. Grease can appear similar to intraorbital air on cross-sectional imaging, and clinicians should have a high index of suspicion for retained intraorbital grease and know how to recognise this. In this case, we will share the clinical and radiological findings as well as management of retained intraorbital grease.

ABSTRACT

This study determined the effectiveness of three deidentification methods: use of a) a black box to obscure facial landmarks, b) a letterbox view to display restricted facial landmarks and c) a half letterbox view. Facial images of well-known celebrities were used to create a series of decreasingly deidentified images and displayed to participants in a structured interview session. 55.5% were recognised when all facial features were covered using a black box, leaving only the hair and neck exposed. The letterbox view proved more effective, reaching over 50% recognition only once the periorbital region, eyebrows, and forehead were visible. The half letterbox was the most effective, requiring the nose to be revealed before recognition reached over 50%, and should be the option of choice where appropriate. These findings provide valuable information for informed consent discussions, and we recommend consent to publish forms should stipulate the deidentification method that will be used.

ABSTRACT

The conjunctiva, an under-researched yet incredibly important tissue, plays key roles in providing protection to the eye and maintaining homeostasis of its ocular surface. Multiple diseases can impair conjunctival function leading to severe consequences that require surgical intervention. Small conjunctival defects can be repaired relatively easily, but larger defects rely on tissue grafts which generally do not provide adequate healing. A tissue engineering approach involving a biomaterial substrate capable of supporting a stratified epithelium with embedded, mucin-secreting goblet cells offers a potential solution. As a first step, this study aimed to induce stratification of human conjunctival epithelial cells cultured on electrospun scaffolds composed from poly(ε-caprolactone) (PCL) and decellularised tissue matrix (small intestinal submucosa (SIS) or urinary bladder matrix (UBM)) and held at the air/liquid interface. Stratification, up to 5 cell layers, occurred more frequently on scaffolds containing PCL + UBM. Incorporation of these decellularised tissue matrices also impacted material properties, with significant changes occurring to their fibre diameter, tensile properties, and chemical composition throughout the scaffold structure compared to PCL alone. These matrix containing scaffolds warrant further long-term investigation as a potential advanced therapy medicinal product for conjunctiva repair and regeneration.

ABSTRACT

PURPOSE: To describe how a vertical lid split helps excision and reconstruction of conjunctival tumors. METHODS: All patients with a limited view of conjunctival tumors involving the fornices underwent a vertical lid split procedure to improve access during resection and reconstruction. RESULTS: There were 11 cases where vertical lid splits were performed to assist excision and reconstruction of conjunctival tumors on patients between 2015 and 2019. There were 4 male and 7 female patients, 50-85 years of age, mean age 67.2 years. Four patients had invasive malignant melanoma, 2 melanoma in situ, 3 invasive squamous cell carcinoma, and 2 squamous cell carcinoma in situ. The authors have had no local reoccurrences in 9 patients (follow-up 8-54 months, mean 18 months). One patient's deep margins were involved and proceeded to exenteration, and 1 patient died from liver metastases. CONCLUSIONS: A vertical lid split incision of either or both eyelids, well away from the visible tumor edge splays the lid open allowing the whole conjunctival surface to be stretched out and viewed as a single flat sheet. This aids excision and reconstruction of the tumor, potentially reducing the risk of seeding and simplifying the reconstruction.

ABSTRACT

Orbital exenteration is a rare radical procedure used for the treatment of locally invasive or potentially life threatening orbital tumors. The procedure results in significant visual and psychosocial disability. Recently there has been a shift toward a subtotal extenteration with maximum preservation of orbital tissue and globe in appropriate cases. We describe the management dilemma of a patient with orbital extension of a frontal sinus squamous cell carcinoma. The patient underwent combined craniofacial and transnasal macroscopic excision with globe preservation. Traditional approach for a sinus tumor that has invaded the orbit would be an exenteration. The favorable outcome of the case reported here raises the possibility of considering this approach more frequently.

ABSTRACT

Orbital involvement in chronic lymphocytic leukemia (CLL) is highly unusual and most commonly involves hemorrhage or soft tissue infiltration in advanced disease. We report a case of rapid onset bilateral orbital muscle infiltration as the presenting feature of early stage CLL. In addition, we demonstrate clinico-pathological correlation with an identical chronic B-cell lymphocytic infiltrate in both orbit and bone marrow, with good response of the orbital disease to local radiotherapy.

ABSTRACT

A forty year old female presented with a swelling above the medial canthal tendon, later diagnosed as a mucus secreting adenocarcinoma. This rare carcinoma arose within an inverted papilloma lined by ciliated respiratory type columnar epithelium incorporating numerous goblet cells. We were only able to find two such cases reported in the literature. The history, clinical features, histological characteristics and management are discussed. The case highlights the importance of early recognition of these tumours along with need for aggressive management.

ABSTRACT

OBJECTIVE: To describe the technique and indications for an endoscopic-assisted approach to orbital roof lesions. MATERIALS AND METHODS: The technique was used for six cases of orbital roof lesions. An anterior orbitotomy was performed via an upper eyelid skin crease incision. Areas of the lesion behind the superior orbital rim or abutting the dura were removed with the aid of a rigid Storz 3-chip video-endoscope with 30-, 45-, or 70-degree tip. RESULTS: Six patients with lesions involving the orbital roof were treated using endoscopic-assisted curettage. There were five males and one female with a mean age of 39.6 years (range, 5 months to 67 years). There were two cases each of cholesterol granuloma, Langerhans' cell histiocytosis, and orbital dermoid. The lesions were successfully removed in all cases with a good outcome. Average follow-up was 2.6 years; range, 6 months to 5 years. CONCLUSION: This technique may be suitable for selected erosive lesions of the superior orbit involving the orbital roof.

ABSTRACT

OBJECTIVE: To perform a multicenter review of the clinical features and treatment of 31 patients with idiopathic sclerosing orbital inflammation. METHODS: We included all patients with histologically confirmed idiopathic sclerosing orbital inflammation from 5 regional orbital centers. We reviewed the case notes to determine the clinical presentation, diagnostic features, and response to treatment. The main outcome measures were duration and nature of symptoms, anatomical location of disease, histopathological findings, treatment modalities, treatment efficacy and adverse effects, and final clinical status. RESULTS: We included 13 male and 18 female patients ranging in age from 7 to 83 years. The average duration of symptoms at presentation was 13.4 months. There was a predilection for the lateral and superior quadrants. Thirteen patients had apical disease, and 4 had extraorbital involvement. Histopathological findings invariably showed sclerosis associated with a sparse mixed cellular infiltrate. Twenty-seven patients were treated with oral prednisolone, response to which was good in 9 patients, partial in 11, and poor in 7. Six patients were treated with a second-line immunosuppressive agent, and 6 received radiotherapy. The response to radiotherapy was generally poor. CONCLUSIONS: Idiopathic sclerosing orbital inflammation is a rare condition that can be difficult to diagnose and manage. Early intervention with immunosuppression in the form of corticosteroids combined with second-line agents can result in control and even regression of the disease.

ABSTRACT

PURPOSE: To describe ophthalmic manifestations in a series of patients with multiple myeloma (MM) and review the literature. DESIGN: Retrospective case series. METHODS: Review of all cases with ophthalmic manifestations of MM seen at the Department of Ophthalmology, Royal Adelaide Hospital, between 1987 and 2002. RESULTS: Of all patients with MM who were managed at the Royal Adelaide Hospital in the study period, only 8 were referred to the Ophthalmology Department with ophthalmic manifestations. Five males and 3 females with a mean age of 61.25 years (range 42-78) who exhibited ophthalmic manifestations were studied. Six patients (75%) had known MM at the time of their ophthalmic evaluation. Four patients (50%) had neuro-ophthalmic symptoms resulting in diplopia or visual disturbances. Three patients (37.5%) presented with orbital involvement and 1 (12.5%) with hyperviscosity retinopathy. Five patients (62.5%) died within 2 months of their ophthalmic presentation. CONCLUSION: Ophthalmic manifestations of MM are uncommon and diverse. They may appear at the initial presentation of the disease or occur late in the disease process. Awareness of the possible manifestations may lead to an earlier diagnosis and have a positive influence on the disease course.

ABSTRACT

A 14-year-old boy with 11 mm of proptosis and exposure keratopathy secondary to an orbital lymphangioma underwent surgical debulking with a carbon dioxide laser through a lateral orbitotomy combined with a 3-wall orbital decompression. The proptosis was reduced by approximately 2 mm as a result of the debulking procedure, but a further 5 mm reduction was achieved with the orbital decompression. No serious adverse effects were encountered. Bony orbital decompression may be a useful alternative treatment in patients with severe proptosis secondary to orbital lymphangioma.

ABSTRACT

PURPOSE: To evaluate the rate of recurrence of horizontal laxity or lid malposition and suture-related complications associated with the use of an absorbable suture in the lateral tarsal strip procedure. DESIGN: Prospective, interventional, consecutive case series. METHODS: A prospective study. SETTING: Institutional. PATIENT POPULATION: One hundred patients with horizontal lid laxity associated with ectropion or entropion. Patients with paralytic ectropion or ocular prostheses were excluded. INTERVENTION: One hundred and five lateral tarsal strip procedures were performed using a 6-0 polyglactin suture. These were combined with full-thickness skin grafts (34), internal (55) or external (23) retractor plications, and inverting sutures (4) as required to correct the lid malposition. MAIN OUTCOME MEASURES: Recurrence of horizontal laxity or lid malposition and suture related complications were the main outcome measures. Suture related wound infection was diagnosed clinically by the presence of pus associated with wound breakdown. RESULTS: One patient failed to reach 3-month follow-up and was excluded. There was one recurrence of horizontal laxity after a mean follow-up period of 9.1 months. Four patients developed lateral canthal wound infections, compared with none at the other operative sites. The 95% confidence intervals for infections in the tarsal strip procedure were 1.1% to 9.6%, which were significantly greater than zero (P < .0001), the infection rate for the other procedures. CONCLUSION: A 6-0 absorbable suture may be used for the lateral tarsal strip and does not lead to a recurrence of horizontal laxity. It does not appear to reduce the wound infection rate associated with this procedure.

ABSTRACT

PURPOSE: To assess the role of the Staar Surgical implantable contact lens (ICL) for the correction of pseudophakic anisometropia. SETTING: Oxford Eye Hospital, Oxford, and Rosen Eye Center, Alexandra Hospital, Manchester, United Kingdom. METHODS: Six patients with pseudophakic anisometropia ranging from 2.0 to 7.9 diopters (D) (mean 4.4 D) had ICL implantation as an alternative to intraocular lens (IOL) exchange or conventional piggyback IOLs. RESULTS: All patients had a reduction in anisometropia to asymptomatic levels. The mean reduction was 3.15 D. No patient experienced adverse effects. CONCLUSIONS: The implantable contact lens offers an alternative approach to the management of pseudophakic anisometropia that avoids some of the risks associated with IOL exchange, corneal refractive surgery, and conventional piggyback IOLs.
