Chikungunya fever presenting with acute optic neuropathy.

Chikungunya fever is a vector borne virus that typically causes a self-limiting systemic illness with fever, skin rash and joint aches 2 weeks after infection. We present the case of a 69-year-old woman presenting with an acute unilateral optic neuropathy as a delayed complication of Chikungunya virus (CHIKV) infection contracted during a recent trip to the West Indies. She presented to our ophthalmology department with acute painless visual field loss in the right eye and a recent flu-like illness.

Comparison of the utility of Pascal dynamic contour tonometry with Goldmann applanation tonometry in routine clinical practice.

Purpose: To compare the utility of Pascal dynamic contour tonometry with Goldmann applanation tonometry in routine practice

Methods: In a prospective study, 10 clinicians recruited 97 patients attending outpatient ophthalmology appointments. Intraocular pressure was measured with both Pascal and Goldmann tonometry in a randomized order. The time taken with each instrument, the number of measurements required to obtain a satisfactory Pascal reading (Q1 to Q3) and the quality value of this reading were recorded.
