We report an unusual case of scleral and lid necrosis from suspected self-harm and the management of the resultant scleral perforation with a tarsoconjunctival 'Hughes' flap. To our knowledge, no previous literature describes such a technique in the repair of toxic scleral melts. Our case describes an alternative use for a Hughes flap in providing tectonic support and helping to restore the integrity of the globe in a complex case where conventional methods of 'patching' had failed.
To analyse the long-term outcome of small margin (up to 2 mm) excision of clinically well-demarcated primary periocular basal cell carcinomas (BCCs). Retrospective evaluation of 185 patients with excised well-demarcated primary BCCs at a minimum of 11 years following excision. All patients underwent tumour excision with maximum margins of 2 mm. Resulting defects were, if possible, closed directly. Reconstruction requiring flaps or grafts was delayed until receipt of the histological report, which was obtained in all cases. Of 185 patients evaluated, 69 (37.3%) were still alive at the time of the study, at least 11 years post excision. One-stage excision and direct closure was performed in 60/69 patients (86.96%). In 9/69 patients (13.04%), excision was undertaken with reconstruction 4 days later, after receipt of the histopathology report. Histological assessment confirmed complete initial excision in 59/69 patients (85.5%) rising to 68 (98.6%) after two excisions. Mean follow-up was 13 years, with no recurrence in the living cohort. Three deceased patients had a recurrence, one of whose tumour was reported histologically as incompletely excised but declined further surgery, giving an overall recurrence rate of 3/185 (1.62%). For patients who completed treatment, the recurrence rate was 2 in 184 (1.09%). Six of the sixty-nine patients (8.7%) developed new tumours on the contralateral eyelid or the forehead. Primary, clinically well-demarcated periocular BCCs can be safely treated using small (up to 2 mm) excision margins in a one-stop setting with immediate reconstruction for those defects which can be closed directly without recourse to flaps or grafts. A retrospective study of 185 patients who had small margin (≤2 mm) excision of clinically well-demarcated primary periocular BCCs demonstrated a recurrence rate of 3/185 (1.62%) at a minimum of 11 years’ follow-up.
Purpose: To audit and analyse the accuracy of current biometric formulae on refractive outcomes following cataract surgery in patients with axial length less than 22 mm. Methods: A total of 84 eyes from 84 patients with axial length <22 mm were identified from consecutive patients undergoing cataract surgery retrospectively at a single university hospital. All subjects had biometry using the IOLMaster (Carl Zeiss Meditec, Inc, Dublin, CA, USA) and a Sensar AR40 intraocular lens implant (Abbott Medical Optics, CA, USA). One eye from each patient was randomly selected for inclusion. Prediction errors were calculated by comparing expected refraction from optimized formulas (SRK/T, Hoffer Q, Haigis and Holladay 1) to postoperative refraction. A national survey of ophthalmologists was conducted to ascertain biometric formula preference for small eyes. Results: The mean axial length was 21.00 +/- 0.55 mm. Mean error was greatest for Hoffer Q at -0.57 dioptres. There was no significant difference in mean absolute error between formulae. SRK/T achieved the highest percentage of outcomes within 0.5 dioptres (45.2%) and 1 dioptre (76.2%) of target. Shallower anterior chamber depth was associated with higher mean absolute error for SRK/T (p = 0.028), Hoffer Q (p = 0.003) and Haigis (p = 0.016) but not Holladay (p = 0.111). Conclusion: SRK/T had the highest proportion of patients achieving refractive results close to predicted outcomes. However, there was a significant association between a shallower anterior chamber depth and higher mean absolute error for all formulae except Holladay 1. This suggests that anterior chamber depth with axial length should be considered when counselling patients about refractive outcome.
Ophthalmologists are well aware of the ocular risks of EL and routinely survey for these.However, ensuring cardiovascular assessments may be less-regularly documented.Herein we audit documentation of whether patients with EL are known to cardiologists, geneticists or physicians for their systemic cardiovascular risks.Eligible patients were identified from the database of a tertiary ophthalmic centre: Moorfields Eye Hospital, London.A database search between 1 January 1959 and 31 December 2011 was performed.The inclusion criteria were all referrals for EL or for syndromes associated with EL.Patients were excluded if the EL diagnosis was not confirmed, or if patients were subsequently seen elsewhere.The standard of the audit was that all patients should have documentation that the patient is under cardiovascular review.In all, 191 patients fulfilled the inclusion criteria.Ninetyseven patients (51%) had documentation that they were under cardiovascular review.Of these, 38 (20%) were documented to be known as having cardiovascular issues, while 59 patients (31%) did not.A total of 94 patients (49%) had no documentation regarding cardiovascular problems.Our findings describe the lack of documentation ensuring cardiovascular review for patients with EL.Ophthalmologists are well aware that the most common cause of EL is MFS and associated cardiovascular risks.It is important for patient safety that these patients are known to cardiology or medical services.Ophthalmologists first see ~40% of patients with MFS [7].It is critical therefore to ensure that patients with EL are under the care of appropriate physicians.There are currently no guidelines on referral pathways for patients who present to ophthalmologists with EL, suggesting the need to review investigation and management of this cohort.

Background Current guidelines vary regarding when to remove contact lenses prior to performing biometry, and there is no clear evidence behind these guidelines. This study aimed to determine the effect of soft contact lens wear on biometric measurements by examining the change in predicted lens power for emmetropia at several time points following removal of soft contact lenses. Methods A prospective, controlled study of healthy soft contact lens wearers. Biometry was performed immediately after removing contact lenses and then after 2, 4 and 7 days of no contact lens use. Healthy non-contact lens wearers were used as controls. All measurements were taken with the Zeiss IOLMaster. Results In all, 14 subjects and 13 controls were recruited. There was no significant difference in age or gender between groups. Eight of the fourteen subjects wore daily disposable CLs, two wore 2-weekly and four wore monthly soft CLs. Measurements from controls and contact lens-wearing subjects showed similar degrees of variation over time. The within-subject SD in predicted intraocular lens (IOL) power for emmetropia for contact lens wearers was 0.20 D (95% CI 0.16–0.25 D) compared to 0.18 D (95% CI 0.12–0.26 D) for controls. Conclusions There is a significant variation in UK practice regarding advice on the timing of cessation of contact lens wear prior to having biometry performed. Our study suggests that it is likely that soft contact lens wearers are currently being advised to remove their contact lenses for an unnecessarily long period of time prior to having biometry performed.
We present 2 elderly patients who developed necrotizing scleritis after cataract extraction in which the wound was sutured with polyester. In the first case, a 73-year-old woman who had right phacoemulsification via a limbal incision developed necrotizing scleritis 8 months after surgery. The eye became progressively painful and phthisical, necessitating enucleation. Microscopic examination of the enucleated globe showed a predominantly lymphocytic infiltration of the ocular tissues with no evidence of an infectious agent. In the second case, a 78-year-old woman had bilateral extracapsular cataract extraction through a limbal incision closed with a polyester suture. The patient presented 3 years later with bilateral necrotizing sclerokeratitis. No underlying systemic vasculitis or autoimmune condition was identified in either patient. To our knowledge, the association of necrotizing scleritis after intraocular surgery and polyester fiber suture material (Mersilene) has not been described.
AIMS To assess the efficacy of extracapsular cataract surgery using the anterior chamber maintainer (ACM) without the use of viscoelastic. To compare the effects of this surgical technique on non-diabetic and diabetic patients. METHODS A prospective single armed clinical trial of 46 eyes in 46 patients undergoing cataract surgery using the ACM without viscoelastic. Patients were assessed preoperatively and at 3 weeks, 3 months, and 12 months postoperatively. The main outcome variables included visual acuity, surgically induced astigmatic change (SIAC), changes in endothelial cell density (ECD), and morphology affecting the central and superior regions of the cornea. RESULTS Postoperatively, 56% and 70% of patients had unaided visual acuities of 6/12 or better at 3 weeks and 3 months respectively. Even after excluding those patients with pre-existing maculopathy (including diabetic maculopathy), there remains a significant difference between the non-diabetic and diabetic groups in terms of the proportion of patients attaining an unaided visual acuity of 6/12 or better at both 3 weeks (p=0.003) and 3 months (p=0.001). Three months postoperatively, the SIAC based upon the keratometric and refractive data was 1.1 dioptres (D) and 1.3 D respectively. There was no statistically significant difference in the SIAC when the non-diabetic and diabetic groups were compared. The mean central and superior endothelial cell losses at 3 months postoperatively were 16% and 22% respectively and at 12 months postoperatively were 20% and 25% respectively. The diabetic group demonstrated greater endothelial cell losses and a more marked and protracted deviation of endothelial cell morphology from normality when compared with the non-diabetic group; however, the differences did not reach statistical significance. CONCLUSIONS The efficacy of small incision cataract surgery using the ACM in terms of visual outcome and induced astigmatism is comparable with the results obtained using other techniques that utilise a similar size of incision. However, in view of the magnitude and range of the endothelial cell losses associated with this technique the concurrent use of viscoelastic is suggested. There does not appear to be a statistically or clinically significant difference between non-diabetic and diabetic patients in terms of the magnitude of the endothelial cell losses or in the wound healing response in the 12 months after cataract surgery using the ACM.
