Oral ulcers as a presentation of secondary syphilis.

The incidence of syphilis is increasing, and it typically presents in patients with known risk factors, often to genitourinary physicians. Patients presenting to a dermatologist or ophthalmologist will more likely have secondary syphilis, with the potential for having the associated complications. Early recognition is therefore vital to limit both the disease and risk of further contact spread. In this review, we include two case histories demonstrating the value of recognizing oral signs. Additionally, we review the currently accepted diagnostic and therapeutic recommendations.

Training in cataract surgery in Spain: analysis of the results of a survey of the European Board of Ophthalmology in a Spanish cohort.

INTRODUCTION: A survey conducted by the European Board of Ophthalmology (EBO) revealed significant differences in the surgical training of the ophthalmology residents in Europe, including a disparity between the sexes and a variation in the experience on cataract surgery (CC) between them. This study is about the Spanish sub-cohort of the survey, and its objective is to present and analyse the peculiarities of ophthalmology training in Spain within the European context, as well as discussing ways to harmonise and improve that training throughout the EU. METHODS: We analyse data of the Spanish participants in the EBO exams, defining subgroups by the Autonomous Communities existing in Spain. RESULTS: 93 of 135 requested participants (68.9%) responded. A 60.2% passed the EBO exam between 2021 and 2022, being mostly women (65.59%) aged 31 years old on average. The 91.4% were right-handed, coming from 13 of the 17 Spanish autonomous communities, although mostly from the Community of Valencia, Madrid and Catalonia. Respectively, 16.1%, 3.2% and 8.7% of the respondents said they have completed 10 or more training sessions on animal eyes, synthetic eyes and through the virtual reality simulator. This training was correlated with greater self-confidence in the management of a posterior capsular tear during surgery (p .025). All respondents manifested to have already performed stages of the CC. The average number of operations reported was 181.6 with regional disparities. A significant difference is observed between the sexes against women (-28.3%, p 0.03). DISCUSSION: Ophthalmologists in Spain, much more than other European countries, have greater opportunities for surgical training, with surgical procedures during the residency, that nearly triples those made by the others. Spanish women refer, like their European colleagues, to be in disadvantage in learning opportunities about cataract surgery. The Simulation Based Medical Education (SBME) allows to respond to the training deficit and complements the training on the patient. Although we demonstrate a significant correlation between the number of procedures carried out and self-confidence to operate simple cases, the SBME would be a complementary tool in self-confidence in front of a complication like capsular rupture. CONCLUSION: Spain massively adopts the model named by us "surgery for all", despite the underrepresentation of women in this area, emphasising a need for cultural change that the SBME could facilitate.

Diagnosis of Alagille syndrome-25 years of experience at King's College Hospital.

OBJECTIVE: The aim of the study was to study the clinical and histological features of Alagille syndrome (AGS) at presentation comparing the value of the various modalities before the implementation of genetic diagnosis. PATIENTS AND METHODS: We performed a retrospective analysis of the records of 117 children diagnosed as having AGS after referral to King's College Hospital between 1980 and 2005. RESULTS: Cholestasis was seen in 104 of 117 (89%), characteristic facies in 91 of 117 (77%), posterior embryotoxon in 72 of 117 (61%), butterfly vertebrae in 44 of 117 (39%), heart disease (most often peripheral pulmonary stenosis) in 107 of 117 (91%), and renal disease in 27 of 117 (23%). Serum cholesterol levels of >5 mmol/L were seen in 52 of 86 (60.4%). Liver biopsy showed characteristic features of paucity of interlobular bile ducts in 59 of 77 (76.6%) children younger than 16 weeks of age, in 10 of 14 (71.4%) between 16 weeks and 1 year of age, and in 8 of 12 (66.66%) older than 1 year of age. Other biopsy findings were those of nonspecific hepatitis and biliary features. Iminodiacetic acid scans showed no excretion of isotope into the bowel after 24 hours in 21 of 35 (60%), and small/no gallbladder on ultrasound was seen in 29 of 104 (27.8%). Eleven of 117 (9.4%) had a diagnostic laparotomy and operative cholangiography, 2 proceeding to Kasai portoenterostomy before referral to our unit. CONCLUSIONS: Clinical features of AGS are not as consistently informative as suggested in the literature. Hypercholesterolaemia is nonspecific but may be a helpful pointer. Histology is not characteristic in 25%; hepatobiliary iminodiacetic acid scan and ultrasound may suggest a false diagnosis of biliary atresia in 60% and 28%, respectively, supporting the concept that infants with liver disease warrant early referral to a specialist centre. The advent of genetic diagnosis will redefine the syndrome with likely effects on the prognosis of the defined group.

Tuberculous keratoconjunctivitis.

A 15-year-old West Indian boy had a left keratoconjunctivitis (KC) initially thought to be allergic in origin. He then developed a facial vesicular skin rash and a diagnosis of herpes simplex was suspected. Viral cultures were negative and there was a poor response to topical antiviral treatment. The KC progressed and became bilateral causing considerable reduction in the visual acuities. He complained of general fatigue and was pyrexial with generalised non-tender lymphadenopathy. There was a shadow in the upper lobe of the right lung. The bronchus was semioccluded by a non-caseating granuloma but no acid fast bacilli were found in the sputum or bronchial washings. In the presence of a strongly positive Heaf test, anti-tuberculous treatment was instituted which led to rapid resolution of all the systemic and ocular signs.

Topical steroid use in the treatment of ocular alkali burns.

BACKGROUND: Ocular alkali burns can be associated with a poor visual outcome. The release of collagenases and proteases after the injury leads to corneoscleral melting. The role of topical steroids in such patients is controversial as they have been postulated to exacerbate corneoscleral melting. METHODS: 30 patients were reviewed retrospectively after admission to King's College Hospital with alkali burns between 1990 and 1993. All patients were treated with an intense and prolonged regimen of topical steroids and topical and systemic vitamin C. RESULTS: 22 patients had mild injuries and eight had severe injuries as estimated by the Roper-Hall grading system. 23 patients were treated with topical steroids for > 10 days and 22 patients were treated with topical vitamin C for more than 10 days. One patient with a severe injury developed corneoscleral melting. CONCLUSION: Prolonged treatment with topical steroids when used in conjunction with topical vitamin C is not associated with corneoscleral melting.

Exogenous Nocardia asteroides endophthalmitis following cataract surgery.

We present a case of Nocardia asteroides endophthalmitis following cataract surgery. It is the second to be reported and the first in which vision has been preserved. Symptoms commenced 5 days after surgery and there followed a chronic relapsing anterior uveitis which lasted for 4 months. Nocardia asteroides was finally cultured from an aqueous aspirate and a combination of specific antimicrobial treatment and surgery resulted in a satisfactory visual outcome. Exogenous nocardial intraocular infection is rare and must be distinguished from fungal infection as the organism is resistant to antifungal agents.

Prenatal diagnosis of orbital heterotopic brain tissue.

Biopsy of fetal tissues is a relatively new procedure for the diagnosis of congenital malformations. The authors report the first case in which this technique has been applied to an orbital mass, in which heterotopic brain tissue was diagnosed by prenatal biopsy and excised in infancy. The wider implications of such intrauterine procedures are discussed.

Bilateral symmetrical branch retinal artery occlusions.

We present a report of a 52-year-old hypertensive patient with documented bilateral symmetrical branch retinal artery occlusions involving the maculae. The patient presented with no visual symptoms and maintained 6/5 unaided visual acuity in each eye. Although the incidence of retinal artery occlusion in hypertensive patients is well documented, symmetrical bilateral branch retinal artery occlusions suggest a possible anatomical vascular predisposition.

Corneal perforation as a complication of epidermolysis bullosa acquisita.

Epidermolysis bullosa acquisita (EBA) is now recognised as a histopathologically distinct condition. Ocular complications of hereditary epidermolysis bullosa (EB) have been well documented, but little has been reported with respect to the ocular manifestations associated with the acquired form. A patient with EBA and sarcoidosis--an association that does not appear to have been previously reported--developed spontaneous peripheral corneal melting and perforation. The defect healed with the use of a bandage contact lens, antibiotics, mydriatics and pulsed intravenous steroids, and resulted in a satisfactory visual outcome.

Blindness in the city of Nottingham (1980-1985).

An analysis has been made of data obtained from all available blind and partially sighted registration forms (Form BD8) for the City of Nottingham between the years 1980 and 1985 inclusive. Senile macular degeneration was the commonest cause for registration followed by glaucoma and then diabetic retinopathy. The rate of registration per 100,000 of population for different age groups is compared with similar figures for all England obtained 10 years previously. There is an apparent increase in the rate of registration of senile macular degeneration but a reduction in the rate of registration of glaucoma and cataract. The rate of registration of patients with diabetic retinopathy is also reduced but only in elderly patients.

The effect of surgery on the AC/A ratio.

The accommodative convergence/accommodation (AC/A) ratio is used clinically as a diagnostic tool in the assessment of convergence excess and near esotropia and the differentiation of true and simulated divergence excess. An abnormally high AC/A ratio has been implicated in the aetiology of some forms of strabismus but the evidence for alteration in the ratio following surgery is inconclusive. In a prospective study of 38 patients the effect of routine squint surgery was investigated in concomitant strabismus. The AC/A ratio was found to decrease significantly after surgery in both esotropes and exotropes. Furthermore a trend was demonstrated which suggested an increased risk of overcorrection in esotropes with a high (> or = 7:1) pre-operative AC/A ratio.

Bilateral external chalazia presenting as granulomas of the lower eyelids.

A 2-year-old oriental boy with bilateral symmetrical external chalazia is described. The diagnosis of this very unusual clinical picture became apparent only after histological examination and consultation with an eyelid specialist.

Screening for ophthalmic manifestations of sickle cell disease in the United Kingdom.

There are marked variations in the manifestations of sickle disease in different populations. The ocular complications of this condition amongst the Afro-Caribbeans living in the United Kingdom have not previously been reported. We present the preliminary results of an ophthalmic screening programme at King's College Hospital, London. One hundred eyes of 50 patients with sickle cell disease were assessed. Full ocular examination was performed including fundus fluorescein angiography. We have looked at the haematological and clinical profile of the patients involved as well as the number of days spent in hospital during the year preceding the eye examination. The incidence of grade II retinopathy was found to be significantly higher than grade I in SC disease. This concurs with the results of the Jamaican screening and confirms that these patients are at higher risk of visual impairment than those with SS disease. Our results also agree with the Jamaican experience which suggest that visual morbidity is mostly due to complications of proliferative sickle retinopathy (PSR). However, the findings in patients without proliferative changes are different; in particular, angioid streaks leading to disciforms are an important cause of visual loss in Jamaica, but were not seen in any of the 98 eyes examined in this study. No correlation was found between the grade of retinopathy and age, sex, systemic complications and various haematological parameters except for the percentage of haemoglobin F, which was significantly higher in patients with grade I (7.6) compared with grade II (4.2) retinopathy (p = 0.0127).

Erythrocyte stearic to oleic acid ratio in patients with ocular melanoma.

The main characteristics of malignant cells include increased metabolism and capacity for division which are associated with high membrane fluidity. Membrane fluidity is in turn controlled by multiple factors which include the ratio of saturated to unsaturated fatty acids in the cell wall i.e. the Saturation Index (SI). The SI is known to be reduced in neoplastic cells as well as in the circulating erythrocytes of patients with some malignant tumours but not others. It has been suggested that the SI may be useful as a marker of malignancy.

Transscleral diode laser in the treatment of retinopathy of prematurity.

PURPOSE: To assess the outcome of contact transscleral diode laser (TSDL) in the treatment of threshold retinopathy of prematurity (ROP). METHOD: TSDL was performed in 14 eyes of 8 babies who presented to the paediatric ophthalmic service at King's College Hospital between 1996 and 1997 with threshold ROP (median post-conceptual age 26 + 1 weeks, median birthweight 835 g) by a single surgeon. Follow-up ranged from 9 to 41 weeks (median 21 weeks). RESULTS: In 11 eyes (79%) regression of ROP occurred after a single laser treatment with a good anatomical outcome. In 3 eyes (21%) there was an unfavourable response with the development of traction retinal detachment. These include both eyes of one baby who rapidly progressed to stage IV ROP. One other eye developed a fibrotic band a few months after treatment. No significant complications of laser treatment were observed. CONCLUSION: These initial results indicate that TSDL photocoagulation is an effective and technically straightforward alternative to cryotherapy in the treatment of ROP.
