Punctal plugs in children
Mataftsi et al evaluated the safety and efficacy of punctal plugs in 25 children with dry eye syndrome. The most common symptoms were photophobia, soreness and blepharospasm. Concurrent systemic disease was present in 72% of patients. 69% of insertions were performed under general anaesthesia. A substantial improvement in ocular surface disease was noted in all cases: frequency of lubricant use was reduced in 32% and visual acuity improved in 60% of patients. Spontaneous extrusion was the most common complication (19%). (see page 90)
RNFL and visual function loss in glaucoma
Wollstein et al determined the retinal nerve fibre layer (RNFL) thickness at which visual field (VF) damage becomes detectable with structural loss in a prospective cross-sectional study of 72 healthy and 40 glaucoma subjects. Comparison of global mean and sectoral RNFL thicknesses with VF threshold values showed a plateau of threshold values at high RNFL thicknesses and a sharp decrease at lower RNFL thicknesses. A ‘broken stick’ …
