Aim To establish the reliability, efficacy, and safety of disposable prism tonometry and validate its routine use for screening as well as monitoring of glaucoma. Methodology Intraocular pressure (IOP) of 400 eyes of 200 consecutive patients who attended the general ophthalmic clinic was checked with both the Goldmann applanation tonometer and a disposable tonometer prism by an experienced examiner after obtaining informed consent. The data were statistically analysed. Results The mean difference in the IOP between the two types of prisms was 0.1 mmHg (SD71 mmHg). Conclusion Disposable prism tonometry provides a reliable, effective, and safe alternative to Goldmann reusable prism tonometry for routine screening as well as monitoring of glaucoma with the advantages of eliminating the need for chemical disinfection and therefore eliminating the risk of crossinfection.

Patients who chose to have excimer laser PRK based their choice of a unit on reputation of the staff and hospital but also on having care and follow-up by a consultant ophthalmic surgeon, high standards of equipment, continuity of care, and a comprehensive review system backed up by ready accessibility to staff members. Although proximity of a unit was important, cost appeared less important than the other factors.

The established teratogenicity of antiepileptic drugs raises important issues in women of child-bearing age. While the association between neural tube defects and antiepileptic drugs is well recognised, other congenital malformations are known to occur. We report two siblings with characteristic craniofacial features of Fetal Valproate Syndrome who also had associated ocular and neurodevelopmental problems which would benefit from early recognition and intervention.
