  ABSTRACT: Changes in the UK undergraduate medical curriculum mean that a clinical placement in ophthalmology is no longer a requirement. An ophthalmic assessment is necessary for a full physical examination and failure to elicit and interpret signs could mean missing sight and life-threatening pathology. This study was to investigate current undergraduate ophthalmology teaching. An email questionnaire, about the content and delivery of the ophthalmology teaching, was sent to each UK medical school in 2007/2008. The response rate was 83%. Nineteen (79%) medical schools had a compulsory attachment to the ophthalmology department with an average length of 7.6 days (range 3.5-15 days). There was variation as to how ophthalmology was included in the curriculum. Teaching methods and standards also varied. Finally, assessments ranged from formal written and practical exams in some medical schools to informal or non-existent ones in others. The most striking finding was the variation in ophthalmology education a student may receive, with some students receiving none. It is necessary to improve the profile of ophthalmology and ensure that all students achieve a minimum basic standard.

  ABSTRACT: To determine occurrence of features of intraoperative floppy iris syndrome (IFIS) during cataract surgery in patients taking systemic alpha-antagonists (AA). We prospectively studied patients on AA and who underwent phacoemulsification. The following were recorded: pupil diameter preoperatively, iris flaccidity, iris prolapse and peroperative miosis. We studied 40 eyes of 31 subjects. Mean age was 78 years. Overall, 14 eyes (13 patients) showed signs of IFIS: 9/13 (69%) eyes of patients on tamsulosin, 1/18 (6%) eyes in the doxazosin group, 2/2 prazosin patients, 1/4 eyes in the indoramin group, and 1/2 eyes in two patients on a combination of doxazosin and tamsulosin. Most cases (92%) had only one or two signs of IFIS. Bilateral cataract surgery was undertaken in 9 patients but only one patient (on tamsulosin) had features of IFIS in both eyes, while 4 patients (2 on tamsulosin and 2 on other AA) showed signs of IFIS in one eye only, and 4 patients did not show IFIS in either eye. Most AA were associated with IFIS, but it tends to present as a spectrum of signs rather than full triad originally described. Tamsulosin was most likely to be associated with IFIS; however, its intake does not necessarily mean that IFIS will occur. For patients on AA, the behavior of the iris intraoperatively in one eye is a poor predictor of the other eye. Surgeons should anticipate the occurrence of IFIS in any patient on AA.

• Article: Unilateral syphilitic perioptic neuritis in a patient coinfected with human immunodeficiency virus type 1.

  ABSTRACT: Perioptic neuritis caused by secondary syphilis is a rare ophthalmic manifestation in the HIV-infected host. Early diagnosis and treatment of this condition is required to prevent further visual damage. We report a case of unilateral syphilitic perioptic neuritis in a patient coinfected with HIV-1.
