[Syphilitic chorioretinitis in the immunocompromised patient: a case report].

Syphilitic chorioretinitis is a rare manifestation of secondary syphilis. The Authors report a case of a patient tested positive for human immune deficiency virus. A 26-Year-old man presented with a history of suddenly blurred vision in the right eye. Because of a central scotoma, visual acuity was reduced to counting fingers. Slit-lamp examination found one-plus anterior chamber cells and one-plus vitreous cells. Results of ophthalmoscopic examination showed a large yellow lesion in the macular area with a papillar edema and peripheral vasculitis. Serum and cerebrospinal fluid were positive for syphilitic serology. Visual acuity improved to 20/20 after three courses of intravenous ceftriaxone (2g/day for 15 days). The fundus lesion resolved almost completely, resulting in slight pigmentary changes in the macular area. This case report highlights the need for syphilitic serology in cases of uveitis in immunocompromised patients.

[Iris melanomas. A retrospective study of 11 patients treated by surgical excision].

INTRODUCTION: Iris melanoma, even when a malignant tumor, has a slow progressive course. Surgical treatment is easy because of localization of the tumor but can be accompanied by a range of complications, from photophobia to cosmetic problems. MATERIALS AND METHODS: We reviewed the records of 11 patients with iris melanoma treated by surgical excision with posterior limbus incision. Conventional iridectomy was performed in nine cases and iridocyclectomy in two cases. RESULTS: There were seven females and four males ranging in age from 27 to 76 years. Histologically, 10 tumors were composed of B spindle cells and one was mixed. For all patients, followed up for 1-5 years, final visual acuity was more than 6/10. One patient complained of photophobia and cataract developed in one 76-year-old woman at the end of follow-up. CONCLUSION: Because of the good prognosis of iris melanoma, conservative treatment can be given in most of cases (without local complications). Surgical resection confirms diagnosis after histopathological examination, with good final functional result thanks to scleral tunnel incision, which induces less astigmatism than corneal incisions. In the future, these findings will have to be confirmed by a corneal topography study before and after surgery.

[Characteristics of uveitis presenting de novo in the elderly].

INTRODUCTION: This study aimed to describe the clinical characteristics of uveitis presenting de novo in the elderly. The study design was a description of a retrospectively identified case series. PATIENTS: The records of 193 patients with uveitis referred to Bicêtre Hospital's department of ophthalmology between January 1995 and January 2000 were reviewed. Among these patients, the records of 57 patients with uveitis de novo beginning after age 60 were analyzed. RESULTS: Idiopathic uveitis accounted for the majority of cases. Whereas herpes viruses were the most frequent specific diagnosis, presumed sarcoidosis and birdshot choroidopathy were also identified as diagnostic entities of uveitis presenting for the first time in the elderly. Only three cases of masquerade syndrome were identified, two cases of intraocular lymphoma, and one metastasis of a visceral melanoma. CONCLUSION: Masquerade syndromes are not the leading cause of uveitis in the elderly. Idiopathic uveitis and herpes viruses are the most common etiology found.

[Circumstances of choroid and ciliary body melanoma detection].

PURPOSE: To report and analyze the circumstances of uveal melanoma detection. METHODS: The records of 143 consecutive patients diagnosed in the Ophthalmology Department of Gustave Roussy Institute between September 1994 and September 2001 were analyzed. The study included 66 females and 77 males, aged from 21 to 91 years (mean, 62.75 years). RESULTS: The first symptom was decreased visual acuity in 37% of cases. In 34.9%, there was no functional sign and a systematic fundus exam provided the diagnosis. Of the 143 patients, 18.8% presented alteration of the visual field or scotoma, 9.9% complained of phosphenes, 9% complained of metamorphopsia, and 6.5% complained of floaters. In 5.5% of cases, there was documented tumor growth. In 2%, the presence of extrascleral exteriorization was the first sign. At the time of diagnosis, anterior tumors tended to be significantly larger than posterior tumors (p<0.007). Smaller lesions were significantly associated with a systematic detection of the tumor (p<0.005). Liver metastasis occurred more frequently with ciliary body melanomas (p<0.001), which were more frequently the largest lesions. CONCLUSION: These results emphasize the importance of early detection of uveal melanoma. We recommended frequent fundus examination after pupil dilatation.

[Sturge-Weber syndrome: medical management of choroidal hemangiomas].

PURPOSE: To investigate the outcome of irradiation of complicated choroidal hemangiomas in Sturge-Weber syndrome. PATIENTS AND METHODS: The charts of 6 patients (7 eyes) with Sturge-Weber syndrome and choroidal hemangiomas were reviewed. An exudative retinal detachment was the indication for treatment in all cases. The mean age of the 6 patients was 13 years (range, 4 to 20 years). The minimum follow-up time was 1 year. Patients were checked for initial and final best-corrected visual acuity, fundus examination, fluorescein angiography, and tumor thickness on B-scan ultrasonography. The patients were treated with radiotherapy. A total dose of 20 Grays was applied to 7 eyes: 2 with a circumscribed choroidal hemangioma underwent proton therapy and 5 with diffuse hemangioma were treated by external beam irradiation. RESULTS: Complete resolution of the subretinal fluid was achieved in all cases with the tumor height decreased. Visual acuity improved to 1 line or more in 5 eyes and remained stable in 2 eyes. Two cases that underwent proton therapy developed radiation retinopathy. CONCLUSION: External beam radiation is an effective and safe option in the management of choroidal hemangiomas complicated by retinal detachment. Based on our experience, proton therapy should be reserved for sporadic circumscribed choroidal hemangioma.

[Therapeutic strategy in delayed postoperative endophtalmitis: a report on 15 cases].

PURPOSE: To report the treatment strategies and visual acuity outcomes of chronic postoperative endophthalmitis. MATERIAL: and methods: The authors reviewed the records of 15 patients presenting 3 or more weeks after cataract surgery with intraocular inflammation and treated at Bicêtre Hospital from 1992 to 1998. Group I included 6 consecutive patients treated with vitrectomy and intravitreal antibiotic injection (vancomycin and cefazolin). Group II included 9 consecutive patients treated with intravitreal antibiotic injection (vancomycin and ceftazidime) and irrigation of the capsular bag (vancomycin). The minimum follow-up period was 1 year. RESULTS: In group I, 2 patients had recurrent inflammation. In these patients, the capsular bag and the intraocular implant were removed. In 1 patient there was culture-proven Corynebacterium and in 1 patient a Staphylococcus epidermidis was found. Final visual acuity was 20/40 or better in 5 patients and 20/100 in 1 patient. Visual acuity improved in all cases. In group II no recurrence was seen in the 12-20 months of follow-up. In 2 patients there was proven Staphylococcus epidermidis and in one patient Propionibacterium acnes was found. Final visual acuity was 20/40 or more in 3 patients, 20/100 or more in 4 patients and less than 20/200 in 2 patients. Visual acuity improved in 8 cases. CONCLUSIONS: Intravitreal antibiotic injection with vitrectomy and intravitreal antibiotic injection with antibiotic irrigation of the capsular bag are both effective in the treatment of delayed chronic postoperative endophthalmitis; however, with the second approach, there is minimal surgical trauma and the intraocular implant is retained.

[The phenol red thread first results for the assessment of the cut-off value in ocular sicca syndrome].

PURPOSE: To determine the cut-off value of the phenol red-impregnated thread test (Zone-Quick((R)), Menicon trade mark ) for the diagnosis of ocular sicca syndrome using the ROC (receiver operating characteristic) procedure and to estimate the agreement with the Schirmer I test (without anesthetics). MATERIAL: and methods: Fifty-four consecutive patients (including 50 females) with dry eyes, presumably related to an immune disorder, were recruited on the basis of subjective ocular symptoms and medical history (sicca syndrome). Both the phenol red thread (PRT) test and the Schirmer I test (testing periods, 15s and 5min, respectively) were performed in both eyes in random order. Only the lowest result for each test was used in statistical analyses. The same procedure was applied to 29 normal volunteers (no subjective symptoms). The patient and the control groups were matched for age and gender (mean age, 58.1 and 59.6, respectively). RESULTS: The ROC procedure showed that a cut-off value of 12mm in the PRT test provided the best ratio between sensitivity and specificity (56% and 69%, respectively) for the detection of dry eyes. Using this threshold, the agreement with the Schirmer I test was highly significant (kappa test; P<10(-3)). However, discordant results were observed in 32% of subjects. CONCLUSION: Giving a cut-off value at 12mm, the sensitivity and specificity of the PRT are 56% and 69%, respectively. Even if the agreement with the Schirmer I test is highly significant, 32% of patients have discordant results. These two methods of functional assessment of tear secretion are therefore complementary and further studies remain necessary to better understand the place of both tests in clinical practice.

[Bilateral diffuse uveal melanocytic proliferation associated with systemic carcinoma: two case reports].

Diffuse uveal melanocytic proliferation is a rare paraneoplastic syndrome resulting in rapid bilateral visual loss in patients with systemic carcinoma, caused by proliferation of benign melanocytes within the choroid and the ciliary body. More often visual impairment is due to retinal detachment and cataract. The authors report two cases of presumed diffuse uveal melanocytic proliferation. The first patient was a 74-year-old man with a history of colic carcinoma and hemangioendothelioma of the liver who presented with bilateral multiple nevi of the choroid and extrascleral melanic nodule. The second patient was a 59-year-old woman who presented bilateral multiple nevi of the choroid and a history of carcinoma of the thyroid treated by thyroidectomy 2 years before. There was no evidence of systemic melanoma in either patient. Our two patients showed slow progression with no visual impairment and a longer survival than those described in the literature.

[Clinical course of ocular sarcoidosis in patients with histologically proven systemic sarcoidosis].

PURPOSE: We reviewed the clinical features, natural history and visual prognosis of 9 patients with histologically confirmed ocular and systemic sarcoidosis. PATIENTS: Nine patients underwent a follow-up study between 1993 and 1998. The diagnosis of sarcoidosis was supported by histological evidence of non caseating epithelioid-cell granuloma in tissue biopsy. RESULTS: The mean age was 40.912 years. The mean follow-up was 22.7 months (range 6 - 54 months). The ophthalmic involvement was bilateral in 8 patients. Before treatment, 3 eyes (17.6%) had a visual acuity less than 1/10. Two eyes (11.7%) had a visual acuity less than 3/10 and 10 eyes (58.8%) more than 6/10. The anterior uveitis was granulomatous in 2 eyes (11.7%) and non granulomatous in 8 eyes (47%). Five eyes (29.4%) had a pars planitis. The posterior segment manifestations of sarcoidosis were retinal vasculitis in 7 eyes (41.1%), papillitis in 10 eyes (58.8%) and choroidal granulomas in 2 eyes (11.7%). Seven patients were treated with systemic corticosteroids. One patient was treated with steroid eye-drops. After treatment, one eye (5.8%) had a visual acuity less than 1/10 and 13 eyes more than 6/10. After treatment, the choroidal granulomas disappeared and the intra-ocular inflammation was controlled in all cases. CONCLUSION: Although the number of patients in our series is small, the prognosis for ocular sarcoidosis appears to be good.

[Total anterior opacification on the anterior surface of hydrophilic acrylic implanted lens].

We report a case of cloudiness occurring on the anterior surface of a hydrophilic acrylic foldable intraocular lens 1 year following implantation. This was not a case of phimosis of the capsulorhexis; the dondiness seemed secondary to fibroepithelial proliferation. Successful reopening was obtained with YAG laser. No recurrence was observed during the six months of follow-up.

[Cytomegalovirus retinitis despite normal CD4 levels in an HIV patient. Report of a case].

We report the case of a 54-year-old HIV-seropositive man who was referred to us with unilateral uveitis. The patient had been taking triple antiretroviral therapy (three reverse transcriptase inhibitors) for one week when he presented with blurring of vision in the left eye. Two weeks later, active cytomegalovirus retinitis was suspected after fundus examination and ganciclovir was immediately administered. Even if the CD4 cell count was normal (423/microliter), the diagnosis was confirmed by the presence of CMV in the anterior chamber. This case shows that an elevated CD4 count is not incompatible with CMV retinitis, especially at the beginning of the antiretroviral therapy.

Acyclovir-resistant bilateral keratitis associated with mutations in the HSV-1 thymidine kinase gene.

PURPOSE: To evaluate the contribution of molecular methods for the diagnosis of an acyclovir-resistant HSV-1 bilateral keratitis in an AIDS patient and to report a new point mutation in the nucleotide sequence of the thymidine kinase (tk) gene involved. METHODS: A 31 year old HIV-positive female presented with severe, active, bilateral and sight-threatening keratitis of 6 months duration, which was treated unsuccessfully with acyclovir. After corneal biopsy, samples were analysed by standard virological procedures, in situ hybridization, and PCR. The tk gene was cloned and subsequently sequenced. RESULTS: Conventional virological methods remained inconclusive. However, in situ hybridization and PCR rapidly confirmed the diagnosis of HSV-1 keratitis. The tk gene sequence revealed the presence of five variations previously described in two reference strains, but also a new point mutation at nucleotide position 431 which leads to an amino-acid change at position 144 that supported the hypothesis of a putatively altered functional form of the enzyme. Intravenous foscarnet treatment in an induction regimen was effective and cicatrization occurred within 3 weeks. CONCLUSIONS: PCR and in situ hybridization are effective and powerful techniques when other virological procedures are non-contributive, particularly in immunocompromised patients previously treated with antiviral drugs. The new point mutation identified in the tk gene may be associated with resistance to acyclovir.

Neuronal pathways for the propagation of herpes simplex virus type 1 from one retina to the other in a murine model.

Herpetic retinitis in humans is characterized by a high frequency of bilateral localization. In order to determine the possible mechanisms leading to bilateral retinitis, we studied the pathways by which herpes simplex virus type 1 (HSV-1) is propagated from one retina to the other after intravitreal injection in mice. HSV-1 strain SC16 (90 p.f.u.) was injected into the vitreous body of the left eye of BALB/c mice. Animals were sacrificed 1, 2, 3, 4 and 5 days post-inoculation (p.i.). Histological sections were studied by immunochemical staining. Primary retinitis in the inoculated eye (beginning 1 day p.i.) was followed by contralateral retinitis (in the uninoculated eye) starting at 3 days p.i. Infected neurons of central visual pathway nuclei (lateral geniculate nuclei, suprachiasmatic nuclei and pretectal areas) were detected at 4 days p.i. Iris and ciliary body infection was minimal early on, but became extensive thereafter and was accompanied by the infection of connected sympathetic and parasympathetic pathways. The pattern of virus propagation over time suggests that the onset of contralateral retinitis was mediated by local (non-synaptic) transfer in the optic chiasm from infected to uninfected axons of the optic nerves. Later, retinopetal transneuronal propagation of the virus from visual pathways may have contributed to increase the severity of contralateral retinitis.

[Familial amyloid polyneuropathy type I complicated by chronic glaucoma: 3 cases].

PURPOSE: We report 3 cases of familial amyloid polyneuropathy type I (FAP) with amyloid infiltration of the vitreum and glaucoma. PATIENTS AND METHODS: We reviewed the records of three patients, 2 females and one male, aged 41, 47 and 83 years respectively. The 3 patients had familial amyloid polyneuropathy type I with vitreous infiltration and open angle glaucoma. The two women underwent a liver graft four years earlier. Vitrectomy allowed confirmation of the diagnosis in the 83-year-old patient. Two patients underwent trabeculectomy, histological analysis of the iris and the trabeculum was obtained for one patient. RESULTS: The tree patients presented a polyneuropathy, vitreous infiltration and open angle glaucoma. Results of light microscopy of the iris and the trabeculum showed amyloid deposits in the iris and the trabecular meshworks. CONCLUSION: Familial amyloid polyneuropathy is a hereditary disease which may have a wide range of ocular manifestations. Glaucoma is among the most serious complications of familial amyloid polyneuropathy.

Neuronal propagation of HSV1 from the oral mucosa to the eye.

PURPOSE: To identify possible neuronal pathways leading to herpetic ocular disease after primary oral infection in mice. METHODS: The SC16 strain of herpes simplex virus (HSV)-1 (10(6) plaque-forming units) was injected into the mucocutaneous border of the left upper lip. Animals were killed 2 to 10 days postinoculation (DPI). Spread of the virus in neural structures was studied by immunochemistry. RESULTS: HSV1 first replicated at the site of inoculation and then at the superior cervical ganglion (at 2 DPI). The trigeminal ganglion and the facial nerve fibers were infected by 4 DPI. Infection of the ciliary body and iris occurred at 6 DPI, together with several brain stem nuclei belonging to the autonomic or sensory pathways. Between 8 and 10 DPI, the neural infection gradually cleared up, except for the ipsilateral sympathetic ganglion, and ipsilateral keratitis appeared in some animals. CONCLUSIONS: The pattern of viral dissemination in this mouse model suggests that infection of iris and ciliary body results from transfer of virus in the superior cervical ganglion from sympathetic neurons innervating the lip to neighboring neurons innervating the anterior uvea. Later, zosteriform spread of virus from the trigeminal system may have contributed to the clinical and histologic findings.
