Abstract

Typhoid fever is an acute infectious disease capable of rarely producing ocular complications. These complications are usually seen after the third week, and is notoriously called, as the "Week of complications" by direct invasion or by allergic immune mediated reactions. It can present as uveitis, vasculitis, choroiditis, endophthalmitis or panophthalmitis. We here present an 18 year old boy presenting as retinitis with severe exudation and neurosensory detachment and which was managed successfully with steroids.

Introduction

Enteric fever is a systemic disease caused by gram negative bacteria Salmonella typhi or Paratyphi. Abdominal pain and fever are the characteristic features of the disease. A very high incidence of disease is reported in India and other developing countries due to poor sanitation, access to safe clean drinking water and hygiene among individuals [1, 2].

Typhoid fever related eye manifestations are rare and can lead to blindness and other complications if left undiagnosed and not treated. It has an varied presentation in the form of uveitis, choroiditis, vasculitis, retinitis, endogenous endophthalmitis and even panophthalmitis [3, 4].

Ocular manifestations are usually seen after the third week, and is notoriously called, as the "Week of complications" either due to direct invasion of organism or by an hypersensitivity reaction to organism [5]. Here we want to report an similar case of retinitis, vasculitis and neurosensory detachment developing post typhoid fever in an young individual and which was successfully managed with course of steroids.

We present an 18 year old male native of Bihar residing in Bangalore with chief complaints of DOV in both eyes of 3 days duration with h/o fever 3 weeks back. The reports carried by him revealed he was found positive titers for typhoid bacillus with titers of 1:320 for O antigen and 1:160 for H antigen. He was treated with antibiotics Oflaxacin 400 mg for 2 weeks elsewhere. His fever subsided after initiation of antibiotics but developed diminution of vision 3 days back. His best corrected vision in his right eye was CF at 3mts and in left eye 20/200. His slit lamp examination of the anterior segment of eye was within normal limits.

Figure 1: Anterior segment examination of right and left eye were within normal limits. On dilated fundus examination exudates were seen along the arcade and white feathery patch with haemorrhage at its border suggesting retinitis patch was seen. Disc hyperemia and oedema was noted in both the eyes.
Figure 2: Right eye fundus picture of the patient showing extensive exudation along the arcades, ptch of retinitis with signs of vasculitis and disc edema. Also seen is posterior pole neurosensory detachment.
Figure 3: Left eye fundus picture showing patches of retinitis and disc edema with vasculitis.
Figure 4: FFA picture of the patient showing disc leak in both eyes with extensive vasculitis along the vessels in both eyes
Figure 5: Right eye after two weeks showed reduction in exudation along the arcade and also disc edema was reduced markedly. Macula was also flat in contour.
Figure 6: Left eye also showed marked decrease in retnitis and disc edema after two weeks of treatment with steroids.

DISCUSSION:

Very few cases of typhoid related retinitis have been reported previously.[6.8] Retinits occuring post fever has been reported in many other infections like malaria, chickungunya, and viral fevers.[9,10] The pathogenesis in most of these conditions has been attributed to immune mediated reaction to microbial antigens by the host cells.[9] Our patient was diagnosed as post typhoid retinitis as he had history of fever 3 weeks back which was diagnosed with laboratory investigations and also frank response of fever to antibiotics. Milder forms of these usually do not need any treatment and will resolve on their own. Severe forms like our patient with marked drop in vision, extensive exudation with large retinitis patches and disc oedema respond very well to steroids which will reduce the inflammation and decrease the duration of recovery time.

Conclusion:

Immune mediated Post typhoid vasculitis though manifests aggressively shows a good response to anti-inflammatory medication. Diagnosing the condition may necessitates a close collaboration between a physician and an ophthalmologist at the earliest opportunity.
