Focal Sheathing of Retinal Arteries in Tuberous Sclerosis

Aggressive retinal astrocytoma associated with tuberous sclerosis

We report the case of a patient with an aggressive retinal astrocytoma accompanied with macular edema and neovascular vessels, who was initially treated with intravitreal bevacizumab injections. A 24-year-old male presented to our clinic complaining of visual disturbance in his right eye. At 8 years of age, he had been diagnosed as having tuberous sclerosis complex. Fundus examination demonstra...

Hemimegalencephaly and focal megalencephaly in tuberous sclerosis complex.

We describe two children with complex cortical malformations as well as the typical intracranial manifestations of tuberous sclerosis complex. One child had hemimegalencephaly and the other had extensive focal megalencephaly. These cases are discussed in terms of the current concepts of cortical malformations.

A. J. Dark and S. N. Rizk: Progressive Focal Sclerosis of Retinal Arteries

Aggressive retinal astrocytomas in four patients with tuberous sclerosis complex.

OBJECTIVE To report the clinical and histopathologic findings of retinal astrocytic tumors that showed progressive growth in four patients with tuberous sclerosis complex (TSC). METHODS Four young children each developed an enlarging retinal neoplasm that eventually necessitated enucleation of the affected eye. The systemic findings, clinical course, and histopathologic findings were reviewed...

Two Cases of Proliferative Diabetic Retinopathy with Marked Sheathing of the Retinal Arteries following Vitrectomy

PURPOSE The aim of this paper was to report 2 patients (3 eyes) with proliferative diabetic retinopathy (PDR) who showed marked sheathing of the retinal arterioles that was ultimately attributed to calcification following vitrectomy. CASES Case 1 involved a 65-year-old female with PDR who underwent bilateral vitrectomy for traction retinal detachment. Postoperatively, bilateral retinal redeta...
