  • Clinical, Tomographic, and Angiographic Findings in Patients with Acute Toxoplasmic Retinochoroiditis and Associated Serous Retinal Detachment
    Ocular immunology and inflammation, 2011
    Co-Authors: Moncef Khairallah, Salim Ben Yahia, Rim Kahloun, Bechir Jelliti
    Abstract:

    Purpose: To describe the clinical, optical coherence tomographic, and angiographic findings in patients with acute toxoplasmic retinochoroiditis (RC) associated with serous retinal detachment (SRD). Methods: The study included 60 eyes with acute toxoplasmic RC. Results: Of 60 eyes, 14 (23.3%) were found to have SRD. The SRD was visible on fundus examination in 6 cases and detectable only by optical coherence tomography (OCT) in the 8 remaining cases. It involved the fovea in 9 eyes. There was evidence of associated Choroidal Ischemia on fluorescein angiography and indocyanine green angiography in 5 eyes. Findings seen at the acute stage gradually resolved over a period of 2–6 weeks in all patients. Conclusions: SRD, accurately detected by OCT, is a common complication of acute toxoplasmic RC that should be considered as a potential cause of visual loss. Choroidal Ischemia might contribute to the development of such complication.

  • ACUTE Choroidal Ischemia ASSOCIATED WITH TOXOPLASMIC RETINOCHOROIDITIS
    Retina-the Journal of Retinal and Vitreous Diseases, 2007
    Co-Authors: Moncef Khairallah, S Jenzeri, Sonia Attia, Sonia Zaouali, Salim Ben Yahia, Riadh Messaoud
    Abstract:

    Purpose: To describe eight patients with active toxoplasmic retinochoroiditis (RC) who had features suggestive of acute Choroidal Ischemia. Methods: A retrospective review of the clinical records of 23 consecutive patients with acute toxoplasmic RC was performed. All patients underwent detailed ophthalmic examination at presentation and throughout follow-up, including dilated biomicroscopic fundus examination, fundus photography, fluorescein angiography, and indocyanine green (ICG) angiography. Results: Of 23 patients, 8 (34.8%) had a large area of retinal whitening surrounding a small focus of RC. Fluorescein as well as ICG angiography showed a well demarcated geographic area of early Choroidal hypofluorescence that extended beyond the clinical borders of the white retinal lesion, particularly by ICG angiography. Associated findings for these 8 patients included old retinoChoroidal scars (7 [87.5%]), serous retinal detachment (3 [37.5%]), retinal hemorrhages (1 [12.5%]), and multiple satellite dark dots by ICG angiography (6 [75%]). Seven of eight patients were treated using a combination of antitoxoplasmic drugs and corticosteroids. All findings seen at the acute stage resolved in 2 weeks to 6 weeks. A small atrophic retinoChoroidal scar replaced the active toxoplasmic lesion and was surrounded with mild or moderate retinal pigment epithelium changes that were associated with decreased final visual acuity in 2 patients (25%). Conclusion: Patients with toxoplasmic RC may develop features suggestive of Choroidal Ischemia that can result in a transient or permanent decrease in vision. Choroidal Ischemia can only be suspected clinically, and fluorescein angiography and ICG angiography are required to establish the definitive diagnosis.

  • Sectorial Choroidal Ischemia Associated With Ipsilateral Lacrimal Gland Tumor
    American Journal of Ophthalmology, 1997
    Co-Authors: Moncef Khairallah, Riadh Messaoud, Ahmed Ladjimi, Ridha Gharsallah, Selim Ben Yahia
    Abstract:

    Purpose To report the association of sectorial Choroidal Ischemia with ipsilateral tumor of the lacrimal gland. Methods Case report. In a 62-year-old man, a complete ophthalmologic examination, including fluorescein angiography and computed tomographic scans of the orbit, was performed. The patient underwent an en bloc excisional biopsy of the tumor. Results Fluorescein angiography of the left eye showed extensive sectorial Choroidal Ischemia superotemporal to the optic disk with macular involvement and associated chorioretinal folds. The patient was found to have a benign mixed tumor of the left lacrimal gland. Conclusion The tumor of the lacrimal gland may have compressed Choroidal vessels and short posterior ciliary arteries with subsequent sectorial Choroidal Ischemia.

  • Retinal and Choroidal arterial occlusion in Wegener's granulomatosis.
    American journal of ophthalmology, 2002
    Co-Authors: Tomohiro Iida, Richard F. Spaide, Jeff Kantor
    Abstract:

    Abstract PURPOSE: To describe a patient with Wegener’s granulomatosis presenting with bilateral retinal and Choroidal arterial occlusion. METHODS: A 64-year-old male with Wegener’s granulomatosis was examined using ophthalmoscopy and indocyanine green angiography. RESULTS: The patient had central retinal arterial occlusion in the right eye and branch retinal arterial occlusion in the left eye associated with bilateral Choroidal infarcts. Early phase wide-angle ICG angiography of left eye revealed widespread Choroidal perfusion problems, presumably from the confluence of multiple segmental arterial occlusions. Indocyanine green angiography of the right eye showed similar widespread Choroidal arterial occlusions. CONCLUSIONS: This patient developed loss of vision from multiple arterial occlusions of the retina and choroid. Retinal and Choroidal Ischemia of this patient may have been caused by vasculitis leading to occlusion of retinal arteries and multiple short posterior ciliary arteries.
