RESUMO

PURPOSE: To present a case series of patients with corneal and scleral changes associated with the use of skin-lightening creams. This is the first report of corneal changes with these widely available creams. METHODS: Three patients of West African origin presented with strikingly similar skin, corneal, and scleral changes and were found to have all been using skin-lightening creams containing hydroquinone. Histopathology was obtained for 1 patient. RESULTS: Three patients were referred to the corneal clinics of 2 hospitals with corneal changes and a history of blurred vision for 1 to 3 years. There was a 60-year-old woman from Nigeria and a 68-year-old woman and a 73-year-old man both from Ghana. All 3 had been using skin-lightening lotions containing hydroquinone on their faces for between 3 and 15 years and had black-blue facial pigmentation of exogenous ochronosis, a recognized complication of these creams. Their corneas all had horizontal striae radiating across the posterior corneas with scleral thinning and plaques. Linear brown epithelial pigmentation was observed within the lower third of the corneas. Biopsy of the sclera in 1 patient showed ochronosis. CONCLUSIONS: We present previously unreported eye changes associated with the use of skin-lightening creams containing hydroquinone, with a triad of signs: posterior corneal striae radiating from 3 o'clock to 9 o'clock, thinning and plaques in the sclera, and a normal endothelial cell count. Similar pathological changes are seen in exogenous ochronosis, a recognized skin complication of hydroquinone, are seen in the sclera.

RESUMO

We report an observational study, based on the examination of 319 medical records, identifying the proportion of patients whose driving status was documented on the first and subsequent glaucoma clinic visits. We also established the proportion of patients with documented Driving and Vehicle Licencing Agency (DVLA)-related advice when they did not meet driving standards based on their visual acuity and/or visual fields (VF). On presentation, driving status was assessed in 61% (n=195) patients. Of the remaining 124, 44% (n=55) had their driving status documented at a subsequent visit, on an average 8 years later. Of all patients (78%, n=250) whose driving status was assessed at some stage, 42% (n=134) were drivers. Of the 203 patients who were either drivers or whose driving status was unknown, 37% (n=75) were assessed as having a visual acuity or bilateral VF defect that was below the legal limit for driving, 39 of whom were known drivers. Only 13 were advised to inform the DVLA, and only 5 patients were advised to update their spectacles or listed for surgery to improve their vision. We therefore potentially failed to perform our DVLA duty in 76% (n=57) of patients. We have made suggestions for improving the current performance in this respect based on the findings of this study.

RESUMO

OBJECTIVES: We sought to determine international obstetric opinions regarding the influence of a history of rhegmatogenous retinal detachment on the management of labour and to review the evidence base. DESIGN: A questionnaire containing closed questions, with pre-coded response opinions, was designed to obtain a cross-section of the obstetric opinions. SETTING: Questionnaires were distributed at the 20th European Congress of Obstetrics and Gynaecology in Lisbon, Portugal. PARTICIPANTS: One hundred questionnaires were distributed among obstetricians attending the congress and 74 agreed to participate. MAIN OUTCOME MEASURES: Participants were asked to state their preferred method of delivery in such patients and the reasons for their recommendation. Furthermore, we questioned whether there was any difference in opinions depending on generation. RESULTS: The majority of respondents (76%) would recommend assisted delivery (either Caesarean section or instrumental delivery), whereas the remaining 24% would advise normal delivery. Generation is not a factor influencing this decision. The majority (58%) based their decision to alter the management of labour on their personal opinion of standard of care. CONCLUSION: The literature shows that there is little evidence to support the belief that previous retinal surgery increases the risk of re-detachment of the retina during spontaneous vaginal delivery. This short survey shows that the majority of an international sample of obstetricians questioned does not share this viewpoint. Therefore, unnecessary interventions may be occurring in otherwise fit women with a history of retinal detachment.
