AimTo assess the value of the modified international classification system in screening high-risk patients with bilateral age-related maculopathy (ARM) from those with lower risk characteristics.MethodsIn total, 164 digital images of 106 patients with either bilateral ARM (group A) or the fellow eyes of unilateral exudative age-related macular degeneration (AMD) (Group B) were included. Patients with no signs of ARM in both eyes or those with bilateral late AMD were excluded. The images were randomised and then graded by two masked ophthalmologists based on the modified International Classification of ARM.ResultsThe interobserver consistency between the two graders was high with a Kappa value of 0.82 (SE 0.34, P<0.0001). There were no significant differences in the distribution of the stages of ARM between the two subgroups. Stage 3 was the most common stage in each group for both graders followed by stage 2a in the bilateral drusen group. Stages 1a, 2a and 2b were equally the next common stage in the fellow eye of chordial neovascularisation group.ConclusionA screening system based on clinical characteristics would be of value in risk prediction in a clinical setting. Type of Drusen alone, as identified by the modified International grading system, may not be reliably predictive in screening for patients who are at high risk of developing choroidal neovascularisation.Eye (2006) 20, 199–202. doi:10.1038/sj.eye.6701852; Published online 4 March 2005 [ABSTRACT FROM AUTHOR]

Objective The optimum management of dual anti-platelet therapy (DAPT) in patients undergoing dentoalveolar surgery is controversial. The lack of guidelines has meant clinicians have been left to manage these cases from specialist advice or past experience. In view of this the British Association of Oral Surgeons (BAOS) membership was surveyed to assess current practice.Design An electronic survey consisting of nine closed multiple-choice questions was circulated to all 435 registered BAOS members. A section for open comments was also included. The data was transcribed, organised and reduced to themes by hand and finally analysed.Results One hundred and eighty members completed the questionnaire giving a response rate of 41%. Ninety-two percent of clinicians had direct involvement in managing patients on DAPT and of these 80% had not encountered a bleeding complication. DAPT was continued for simple dental extraction under local anaesthetic by 83% of respondents and 73% for surgical extractions. Two thirds of the respondents did not follow any guidelines but for those that did the most common was the UK Medicines Information protocols. Only 10% of respondents reported a significant post-operative bleeding complication following surgery in patients on DAPT.Conclusion This survey confirmed the continued variable management of patients on DAPT undergoing dentoalveolar surgery. Reported bleeding rates were low with over 75% of patients not having their DAPT treatment interrupted. [ABSTRACT FROM AUTHOR]
