En 1997, une importante exposition organisée conjointement par la France et la Belgique, montrait que le contexte historique, économique, politique et socioculturel existant entre les deux pays de 1848 à 1914 avait eu d’importantes conséquences sur le domaine des arts (Paris‐Bruxelles, Bruxelles‐ Paris, 1848‐1914, Gand/Paris, 1997). La période suivante, par contre, soit l’après‐Première Guerre mondiale, n’a jamais fait l’objet d’une étude systématique. Pourtant celle‐ci est particulièrement riche en modifications et prend place dans un contexte politico‐économique franco‐belge sans précédent. Une approche minutieuse de la présence et de la réception des artistes belges en France durant l’entre‐ deux‐guerres révèle par exemple que la promotion diplomatique de l’art belge en France durant la période n’était pas moins importante que celle mise en place dans la cadre de réseaux individuels et/ou privés. Elle montre aussi que les artistes qui nous paraissent les plus importants aujourd’hui n’étaient pas spécialement ceux dont on parlait le plus à cette époque.

Free-floating iris pigment epithelial cysts in the vitreous are very rare. We report the case of a partially pigmented cyst found on routine examination in the vitreous of a 51-year-old asymptomatic patient. Usually, non-pigmented cysts are derived from the hyaloid system. Pigmented cysts, however, are derived from the iris pigment epithelium. When they are not dislodged, these cysts can be confused with iris melanoma or primary stromal cysts. Treatment is usually unnecessary, unless they become symptomatic., (Copyright © 2013 Elsevier Masson SAS. All rights reserved.)

Epimacular membranes when responsible for a significant loss of visual acuity, generally require treatment by vitrectomy and peeling of the membrane. We report the case of a spontaneous peeling of a macular pucker after cryotherapy of peripheral retinal vasoproliferative tumors. Review of the literature.

Purpose: To evaluate the safety and efficacy of photodynamic therapy in the management of symptomatic circumscribed choroidal hemangiomas (CCH) with exudative activity., Patients and Methods: This prospective nonrandomized study included eight patients referred to us for management of CCH with exudative activity. PDT was applied by diode laser (689 nm) with a light dose of 100 J/cm2 and using verteporfin (6 mg/m2) IV bolus injection. The treatment spot diameter accurately corresponded to the tumor basal diameter (TBD)., Results: The mean tumor thickness before PDT was 3.3 mm (range, 2.7-7.5 mm) and the mean largest TBD was 6.1 mm (range, 5-12 mm). All patients were managed with a single PDT application. After a mean follow-up of 24.2 months (range, 17-29 months), all CCH (100%) showed regression of tumor thickness and complete resorption of the serous retinal fluid; 87.5% of the patients showed a flat tumor scar. All CCH showed overlying PDT-related retinal pigmented epithelium atrophic changes. No case of retinal vascular occlusion or recurrent leakage was documented. Five patients (62.5%) showed visual improvement, one (12.5%) retained stable vision and two (25%) developed worse vision due to chronic exudation-related RPE changes in one patient and preretinal fibrosis in another., Conclusion: PDT using verteporfin offers a safe and effective therapeutic option to manage CCH. Complete resorption of subretinal fluid is usually associated with visual improvement.

Purpose: To study the epidemiology of ocular and orbital lesions referred to an ocular oncology center., Material and Methods: Prospective study of ocular lesions referred between November 1997 and November 2002., Results: A total of 1,257 lesions were recorded in 640 females and 617 males. The mean age at the initial visit was 52 years (range, 0 to 94 years). Patients more than 60 years old accounted for 46% of our series. The lesions were classified into four groups: intraocular lesions (69%), superficial layer lesions (18%), adnexal tissues lesions (7%) and orbital lesions (6%). The posterior uvea was the most frequent localization. The clinical diagnosis of 374 lesions (30%) was confirmed by histological examination. The most frequent tumors were retinoblastoma in children and teenagers, conjunctival nevus young adults, choroidal melanoma in slightly older patients and posterior choroidal nevus in elderly people., Conclusion: This study reviewed the epidemiological characteristics of ocular and orbital lesions referred to an ocular oncology center for their diagnosis, treatment and follow-up.

By presenting this case report describing Parinaud's oculoglandular syndrome, we review the medical literature on its most frequent etiology: catscratch disease, a self-limited, systemic illness caused by a Gram-negative bacillus, Bartonella henselae, principally affecting children under 15 years of age. Typical symptoms include regional lymphadenopathy, fever, malaise, and fatigue, possibly with more severe complications such as splenomegaly, granulomatous hepatitis, and encephalopathy. Ocular manifestations may include follicular conjunctivitis, Parinaud's oculoglandular syndrome, neuroretinitis, optic neuritis, and chorioretinitis. Diagnosis is based on serologic tests, and when necessary, antimicrobial treatment can be considered.

The management of posterior uveal melanoma has evolved tremendously for the past decades and, more recently, there is a trend toward more focal conservative treatment. Transpupillary thermotherapy (TTT) with infrared diode laser (810 nm.) is the newest modality used as primary treatment or as complementary method to radiotherapy or surgical resection in very selected cases of choroidal melanoma. Plaque radiotherapy or charged-particle irradiation is particularly recommended for medium- or small-sized uveal melanoma not suitable to TTT or resection. Special custom-designed plaque radiotherapy (iodine-125) can be used for iris, ciliary body or juxta-paillary choroidal melanoma. The tumor control rate after plaque or charged-particle radiotherapy appears to be similar, but charged-particle irradiation may produce worse anterior segment complications than plaque radiotherapy. Stereotatic radiation therapy for choroidal melanomas may be effective in controlling tumor growth but the number of patients treated with the approach is too small to draw strong conclusions. Local tumor resection using trans-scleral resection is mainly suitable for selected iris, ciliary body, or anterior choroidal melanoma, particularly with smaller basal dimensions and greater thickness. Combined therapies (radiotherapy plus TTT, tumor resection plus TTT) appears to be more effective in decreasing the incidence of intraocular tumor recurrence. Enucleation is still performed for large uveal melanoma when there is no hope for useful vision. Based on the published ophthalmic literature, it seems that enucleation carries the same survival prognosis as each of the conservative treatment modalities.

Stereotactic radiation therapy for choroidal melanoma may be effective in controlling tumor growth, but the number of patients treated with this approach is too small to draw solid conclusions. Local tumor resection using trans-scleral resection is mainly suitable for selected iris, ciliary body, or anterior choroidal melanoma, particularly with smaller basal dimensions and greater thickness. Endoresection may preserve central vision or temporal field when radiotherapy would be expected to cause optic neuropathy. Longer follow-up is necessary to establish the efficacy of tumor control. Combined therapies (radiotherapy plus TTT or tumor resection plus TTT) appear to be more effective in decreasing the incidence of intraocular tumor recurrence. Enucleation is still performed for large uveal melanoma when there is no hope of regaining useful vision. Based on the published ophthalmology literature, it seems that enucleation carries the same survival prognosis as each of the conservative treatment modalities.

Indocyanine green angiography (ICG) is a well-known ancillary test for evaluation of choroidal tumors. The authors review the different images seen in choroidal nevus, melanoma, metastasis, hemangioma, osteoma, and vortex vein varix. ICG appears to be useful for the diagnosis of non pigmented choroidal tumors. In addition, ICG provides good information on the limits of pigmented tumors, particularly for the follow-up of a growing tumor and the choice of treatment.

Cancer may affect the eye and orbit as a direct result of metastatic neoplastic infiltration, compression, or circulating antibodies involving paraneoplastic retinal degeneration. A metastatic tumor to the uvea is the most common form of an intraocular metastatic process. The choroid is the most common site for uveal metastasis; metastases to the ciliary body, iris, retina, optic disk, and vitreous are rare. Approximately one-third of patients have no history of primary cancer at the time of ocular diagnosis. Breast and lung carcinomas for women and lung and gastrointestinal carcinomas for men most commonly metastasize to the eye and orbit. The short-term prognosis for vision is usually good after an individualized therapeutic approach (chemotherapy, hormonal therapy, external beam radiotherapy, or plaque radiotherapy), but the systemic prognosis is poor. The visual paraneoplastic syndromes encompass several distinct clinical and pathological entities including carcinoma-associated retinopathy (CAR), melanoma-associated retinopathy (MAR), and bilateral diffuse melanocytic uveal proliferation (BDUMP). The CAR syndrome affects photoreceptors, MAR is thought to affect bipolar cell function, and BDUMP targets the uveal tract. Identification of circulating antibodies against retinal proteins (recovering, 23-kDa retinal protein; 46-kDa and 60-kDa retinal proteins) serves to recognize the paraneoplastic nature of the patient's symptoms, which frequently develop before the cancer is diagnosed. Anecdotal therapeutic responses are described after systemic steroids, immunoglobulin injection, and plasmapheresis. Recognition of their visual symptoms and ocular findings should alert the ophthalmologist to the possibility of cancer and systemic evaluation should be pursued.

Purpose: To report the results of transpupillary thermotherapy (TTT) for selected posterior pole choroïdal melanomas., Material and Methods: Prospective study including 56 patients (mean age of 61 years) with choroidal melanoma treated with TTT. All treated tumors had either documented growth or clinical risk factors for future growth and for metastasis. The injection of infracyanine green (I CG) was randomized., Results: The mean initial tumor basal diameter was 7.8 mm and tumor thickness was 3 mm. Twenty-seven tumors (48%) touched the optic disc and sixteen (29%) were under the fovea. Among these 56 patients with choroidal melanoma, 47 patients (84%) presented with primary choroidal melanoma. 9 tumors (16%) were late recurrences after conservative treatment. A mean of three treatment sessions was delivered. After a mean follow-up of 30 months, tumor regrowth was documented in 4 patients (7%) and the visual acuity was the same than the pretreatment acuity in 26 eyes (47%). The mean final thickness was 1.8 mm (percent reduction of tumor thickness was 39%). Intraocular complications included retinal fibrosis and/of retinal striae in 12 eyes (22%) and vascular occlusion in 14 eyes (25%). No statistical impact of ICG administration on the tumor regression was demonstrated., Conclusions: This series confirms the efficacy of transpupillary thermotherapy in the management of selected posterior pole choroïdal melanomas.

Purpose: To examine the incidence of orbital complications in patients who underwent primary placement of a porous polyethylene implant (Medpor) after enucleation., Material and Method: Prospective non randomized case series of 75 consecutive patients in whom a porous polyethylene (PP) spherical implant wrapped with homologous sclera was implanted after enucleation., Results: The mean age at the time of enucleation was 42.7 years (range, 1.4 to 80 years). The histopathological diagnoses after enucleation included uveal melanoma in 28 patients, retinoblastoma in 11 patients, phthisis bulbi in 23 patients, neovascular glaucoma in 5 patients, endophthalmitis in 3 patients, ruptured traumatic globe in 2 patients, microphthalmos in two patients, and medulloepithelioma in one patient. Thirty-four patients (45%) had had prior ocular surgery. The prosthesis was fitted after a mean interval of 4.5 weeks (range, 3 to 10 weeks). After a mean follow-up of 20 months (range, 3 to 33 months), there was one case (1%) of conjunctival dehiscence with material exposure secondary to massive postoperative orbital hemorrhage 2 weeks after enucleation. There was no case of orbital cellulitis, implant extrusion, or significant inflammatory response. No PP implant was drilled for peg placement. DISCUSSION-CONCLUSIONS: The anteriorly wrapped porous polyethylene orbital (Medpor) sphere appears to be well tolerated by all age groups with no major complication in primary implantation after enucleation.

Purpose: To report the results of primary transpupillary thermotherapy (TTT) for selected posterior pole choroidal melanomas., Material and Methods: Prospective non randomized study including 34 patients with choroidal melanoma treated with TTT using near-infrared radiation (810 nm) delivered from the diode laser. All treated tumors had either documented growth or clinical risk factors for future growth and/or metastasis. The treatment was delivered using a specially modified infrared diode laser through a slit lamp adaptor. A contact lens was placed on the cornea to view the fundus and focus the laser beam. Treatment was initiated using a 60-second exposure and a low energy level at 300 mW with a 3.0 mm beam width. The energy was raised stepwise by 50 to 100 mW until the surface of the tumor develop a light grayish discoloration. The TTT sessions were delivered at 3-month intervals., Results: Among these 34 patients with choroidal melanoma, 29 patients presented with primary choroidal melanoma. Five tumors (15%) were late recurrences after conservative treatment. The mean initial tumor basal diameter was 7.2 mm and tumor thickness was 2.9 mm. Seventeen tumors (50%) touched the optic disc and 10 (29%) were under the fovea. After a mean of three treatment sessions and 20 months of follow-up, the mean tumor thickness gradually decreased to 2.3 mm at month 3 and 2.0 mm at month 6 after the initial TTT. The percent reduction of tumor thickness was 20% at month 3 and 29% at month 6. The mean final thickness was 1.7 mm. Treatment was successful in 33 patients (97%). Tumor regrowth was documented in one patient (3%) and required plaque radiotherapy. After treatment, visual acuity was the same or better than the pretreatment visual acuity in 21 eyes (62%) and worse in 13 eyes (38%). Intraocular complications included retinal traction in 12 eyes (34%) and vascular occlusion in 3 eyes (9%)., Conclusion: This series confirms the efficacy of transpupillary thermotherapy in the management of selected posterior pole choroidal melanomas. Longer follow-up is still required to assess late local recurrence and the impact on metastatic disease.

In this transversal study, we measure the intra ocular pressure by means of the Goldmann tonometer and a Non-Contact tonometer along with the central cornea thickness in 136 eyes of 73 patients. The statistical analysis of the collected data doesn't allow us to establish a correlation between the variation of the corneal thickness and the difference between the Goldmann tonometer and Non-Contact tonometer measures. The relative precision of the Non-Contact tonometer compared with the Goldmann tonometer doesn't seem influenced by the central cornea thickness.

We report a case of a 4 months old boy with esotropia of the left eye with large bilateral chorioretinal toxoplasmic macular scars. Chorioretinal scars are the most common eye finding in congenital toxoplasmosis and are often located in the macular region. Most infants with congenital infection are asymptomatic at birth but will develop retinal and/or neurologic damage later in life with consequent loss of vision. A routine examination of the fundus and computed tomography of the head can be negative. Serologic testing is essential for the diagnosis and the follow-up of the infection. Every infant with evident or suspected congenital infection by Toxoplasma gondii must be treated by Pyrimethamine, Sulphadiazine and Folinic Acid during at least the first year of life with regular serologic testing and ophthalmologic examination. Neurologic outcome is better with treatment and the risk of chorioretinitis seems reduced.

97 cases of retinoblastoma were studied with particular attention to methods of treatment and results. The series includes 41 unilateral cases (42%) and 56 bilateral cases (58%), giving a total of 153 eyes. Of these, 19 (20%) were familial cases. Immediate enucleation was necessary in 88 of the 153 eyes; 61 eyes received conservative treatment; 4 eyes, including one bilateral case, showed spontaneous recovery (retinomas). Conservative treatment consisted of high-voltage external beam irradiation in 43 cases, cryo or photocoagulation in 12 cases, and radioactive applicators in 6 cases. The mortality-rate in cases with over 2-years follow up is of 11%. In 65% of treated cases the eye was saved, with 87% of these retaining useful or central vision. The most serious complications are radiation retinopathy (19%), cataract (16%) and exsudative retinal detachment (9%).

A retrospective study covering 151 patients was conducted in order to determine the incidence of risk factors (arterial hypertension, diabetes mellitus, smoking, hyperlipidemia, and cardiovascular disorders) in cases of retinal artery occlusion. Occlusion of the central artery was found in 43% of the patients, occlusion of one or several branch arteries in 53%, and cilioretinal artery occlusion in 4%. A monofactorial study of risk factors produced a statistically significant value only for arterial hypertension (P = 0.01). Smoking and diabetic metabolism were not significant, and the correlation with hyperlipidemia was weak (P = 0.08). Forty-six patients were examined by continuouswave Doppler sonography: stenosis of the internal carotid artery was found in 50% of these cases. Pathologic Doppler findings were associated with an embolus in 14 cases (57%) and central artery occlusion in 9 (40%). Since retinal artery occlusion is frequently associated with carotid artery disease, systematic Doppler examination of the carotid vessels and the cardiovascular system should be performed in all patients with retinal artery occlusion.
