Ocular syphilis is a disease known as a great simulator.It can affect the structures of the eye. It often manifests by an anterior uveitis. Posterior segment involvement is very rare and it is exceptionally complicated by exudative retinal detachment. We report the case of a patient with bilateral bullous retinal detachment in the context of ocular syphilis with a good evolution after treatment by penicillin G and corticotherapy.

| Introduction|| |
Ocular syphilis is a disease known as a great simulator. It can affect the structures of the eye. It often manifests by an anterior uveitis. Posterior segment involvement is very rare and it is exceptionally complicated by exudative retinal detachment. We report the case of a patient with bilateral bullous retinal detachment in the context of ocular syphilis.
| Clinical presentation|| |
A 50-year-old woman, diabetic on insulin therapy. The patient reported that her husband was treated for genital syphilis a month ago. She had visited the emergency service for a progressive decrease in bilateral visual acuity. It was 15 days since she had the symptomatology. The ophthalmological examination objectified a visual acuity quantified by counting the fingers in both eyes. The anterior segment examination revealed bilateral nongranulomatous synechiae anterior uveitis with anterior synechiae, keratic precipitates, and transparent lens in both eyes. The fundus was inaccessible in both eyes due to the presence of intense hyalitis in both eyes. Ocular ultrasound showed bullous retinal detachment and hyalitis in both eyes [Figure 1]. On the day of examination, she had a healed genital ulcer.

An exhaustive etiological assessment was performed. The inflammatory biological test and the syphilis serology are reported as positive. The rest of the test was normal, including the infectious assessment (viral serologies; tuberculosis assessment, etc.), immunological and cytobacteriological analysis of cerebrospinal fluid. Similarly, orbito-cerebral magnetic resonance angiography was without abnormalities. After the elimination of other etiologies, we retained the diagnosis of ocular syphilis. The patient was treated with penicillin G 24 million units for 15 days and a corticosteroid bolus for 3 days after the start of antibiotic therapy. The evolution was favorable, the disappearance of the inflammatory signs and a subtotal reapplication of the retina were observed on day 10 of treatment. The patient was seen again 2 months after the treatment [Figure 2]. Macular optical coherence tomography objectified a resolution of the subretinal fluid; fundus examination revealed a flat retina on 360, but visual acuity was low; it was 1/10 in both eyes [Figure 3].

| Discussion|| |
Syphilis is a chronic and infectious disease, it is sexually transmitted and it is caused by the spirochete Treponema pallidum. It can affect the structures of the eye in the secondary and tertiary stages. Anterior uveitis is the mode of the revelation of ocular syphilis, while posterior segment involvement during syphilis is rare, representing only 8% of syphilitic uveitis. The most common ocular manifestations are represented by interstitial keratitis, conjunctivitis, hypertensive anterior uveitis, roseola iris, intermediate and posterior uveitis, vasculitis, serous retinal detachment, and diffuse retinal epitheliopathy. The latter manifests as punctate internal retinitis, chorioretinitis, or acute syphilitic posterior placoid chorioretinitis. Acute syphilitic posterior placoid chorioretinitis is a distinct form of syphilitic retinitis, characterized by the presence of a placoid lesion with a round or oval shape and yellowish color, it involves the macula or a spot very close to the macula. Chorioretinitis may be complicated by bullous exudative retinal detachment. It is rarely described in the literature. The first description of it dates back to 1996 and only a few cases have been described in the literature. It is clinically manifested by a profound progressive visual acuity decline. It is often associated with retinitis, hyalitis, and uveitis., It is the consequence of an alteration of retina function including the internal and external blood barriers of the retina. A study by Pichi et al., who performed B-scans on patients with DRE associated with syphilis, revealed thickening of the choroid, which indicates the presence of choroidal vascular leakage, that causes the bullous exudative retinal detachment. The exudative retinal detachment is often bilateral and it is associated with hyalitis in all cases. Syphilitic uveitis is confirmed by both sensitive and specific serological tests such as fluorescent treponemal antibody absorption and by a nonspecific test such as Venereal Disease Research Laboratory or rapid plasma reagin, which are complementary. Treponema can be found in subretinal fluid analysis of retinal detachment. The test of anti-treponeme antibody titration in cerebrospinal fluid is required to look for associated neurosyphilis.
Patients with syphilitic posterior uveitis should be treated as neurosyphilis. Treatment for syphilitic posterior uveitis is with penicillin G at 18–24 million units daily, given 3–4 million units intravenously every 3–4 h for 10–14 days. Oral corticosteroids can be used to treat inflammatory complications. Treatment prevents disease progression but is not restorative. Jumper et al. used penicillin IV (400 million units every 4 h) for 10–14 days with oral corticosteroids in escalating doses on three patients with exudative retinal detachment. They reported complete resolution of the bullous exudative retinal detachment, but, as in our case, the visual prognosis was poor in eyes where the macula was detached. Even after appropriate systemic treatment, retinal detachment surgery is sometimes required in the absence of reapplication of the retina., Chorioretinitis heals toward retinal hypo or hyperpigmentation and atrophy of the retinal pigment epithelium, this chorioretinal scar is characteristic of syphilis.
| Conclusion|| |
Although the prevalence of syphilis had increased in recent years, bullous exudative retinal detachment remains an exceptional ocular manifestation of syphilis. The ophthalmologist must always know how to evoke this diagnosis because syphilis is a great simulator and early diagnosis is the only way to improve the visual prognosis.
