There is an increasing prevalence with age and in women, especially after 40 years of age [16]. With modern molecular technology, the pathogenesis of HU has been partially unveiled [17]. Also, virological analysis supported the pathogenicity of the virus in the eye, demonstrating that the HTLV-1 provirus load in patients with HU is significantly higher than that in asymptomatic carriers without uveitis [20] and that the proviral load in peripheral blood mononuclear cells correlates with the intensity of intraocular inflammation [21].

Vertical transmission especially through breastfeeding is a very important route of dissemination; therefore, its prevention would have the most significant impact on the spread of the disease [1] , [22]. In endemic areas, prenatal screening for HTLV-1 combined with counselling of seropositive mothers could help prevent and diminish the occurrence of HTLV-1 infection [1]. In the case of pregnancy, a caesarean section should be recommended to minimize the risk of perinatal transmission.

In most African countries and other areas that lack appropriate policies and infrastructures for transfusion services, blood transfusions still represent a risk of HTLV-1 infection. As such, screening for blood donor candidates would be an effective strategy in preventing HTLV-1 transmission. For countries where the disease is not endemic, selective donor recruitment is an option to consider [10].

The patient may present with visual blurring, discomfort and floaters of acute or subacute installation. It is characterized by an anterior uveitis with a granulomatous or nongranulomatous reaction accompanied by vitreous opacities and retinal vasculitis [4] with rare exudative retinochoroidal alterations in one or both eyes [6].

Retinal degeneration, retinal haemorrhages, epiretinal membranes and optic nerve atrophy can occur. Anterior segment alterations might include corneal haze, scarring and neovascularization [26]. The diagnosis is one of exclusion.

Corticosteroid treatment is effective for treating intraocular inflammation in HU. Treatment intensity should reflect the degree of ocular inflammation: mild inflammation can be managed with topical non-steroidal or steroid anti-inflammatory drugs; a sub Tenon corticosteroid injection may be used in moderate vitritis; in severe ocular inflammation, oral corticosteroids should be administered, although long term systemic therapy should be avoided [17].
