Bilateral HIV related ocular surface squamous neoplasia: a paradigm shift.

Four patients with bilateral ocular surface squamous neoplasia attended to at Sekuru Kaguvi Hospital Eye Unit are being presented to alert practitioners that OSSN is potentially a bilateral disease and its prevalence is likely to increase as the life expectancy of HIV infected patients is being positively affected by antiretroviral therapy. Reports on ocular diseases should be clear on laterality to avoid confusion between number of patients affected and number of eyes involved since the two cannot be used interchangeably.
