This paper is a review of choroidal vascular occlusive disorders, as revealed by experimental and clinical observations. Available evidence indicates that Elschnig's spot, mnltifocal acute ischemic choroidopathy, geographic choriodopathy, some of the conditions associated with serous retinal detachment and postoperative outer retinal ischemic necrosis represent acute choroidal ischemic lesions. The various factors which influence the nature and appearance of these lesions are discussed. The role of disturbed circulation of the vortex veins in the production of some major complications following retinal detachment surgery and of choroidal detachment is discussed.

“…Other reports have shown the Amalric sign in association with polyarteritis nodosa, 3 Wegener granulomatosis, 4 and laser photocoagulation of the retina. 5 Jampol et al 6 also noted Amalric sign in two patients from occlusion of the ciliary circulation after ocular compression during general anesthesia.…”

A 71-year-old woman was referred to our clinic because of blurred vision in her left eye the day after uneventful cataract surgery. Best-corrected visual acuity in the right eye was 20/40 and in the left eye was light perception. Anterior segment examination of the left eye revealed a relative afferent pupillary defect and mild inflammatory signs of the conjunctiva and cornea.There was no flare in the anterior chamber. The intraocular lens was well centered in the capsular bag. Fundus examination of the left eye showed a diffuse whitening of the retina at the posterior pole and nasally to the optic nerve with a cherry-red spot of the macula (Figure 1). There was also a peripapillary subretinal hemorrhage involving the papillomacular bundle (PMB) (Figure 1). On the edge of the subretinal hemorrhage, fluorescein angiography (FA) showed a hyperfluorescent area ( Figure 2); indocyanine green angiography revealed that it was originating from dilated polypoidal choroidal lesion ( Figure 2). Nasally to the optic nerve, there were 2 triangular hyperfluorescent areas corresponding to the whitening areas of the retina ( Figure 2). The right eye was unremarkable with mild nuclear sclerosis.Ocular history was unremarkable, and the medical history revealed recently diagnosed medically controlled hypertension. Echocardiography and carotid ecodoppler were negative. On medical record, preoperative best-corrected visual acuity of the left eye was 20/50 with a dense nuclear sclerosis of the lens. Fundus examination did not report any vascular or degenerative disorder of the chorioretinal; neither FA nor optical coherence tomography was performed. The patient underwent uneventful phacoemulsification of the cataract and in-the-bag intraocular lens implantation. No intraoperative or postoperative complications were reported. Because she refused topical anesthesia, a single medial percutaneous peribulbar anesthesia was performed. A 25-gauge 16-mm beveled disposable needle was used. The 5-mL injection contained a 50/50 mixture of 2% xylocaine and 0.5% marcaine, in combination with 150 IU of hyaluronidase. The patient was followed for the next few months, but visual acuity did not recover.This patient is presented for discussion of diagnosis. Dr. Robert W. Wong (Austin, Texas):Dr. Nicolo and Dr. Traverso present an interesting case of a 71-year-old woman with a medical history of hypertension who presented 1 day after an uneventful cataract surgery on the left eye with light perception vision, an afferent pupillary defect, and mild inflammatory signs of the conjunctiva and cornea. Ophthalmoscopically, the left eye showed diffuse retinal whitening with a cherry-red spot suggestive of a central retinal artery occlusion (CRAO) as well as peripapillary subretinal hemorrhage involving the PMB. Fluorescein angiography of the PMB showed hyperfluorescence, and indocyanine green angiography was interpreted as a dilated polypoidal choroidal lesion. The FA also demonstrated two triangular hyperfluorescent areas corresponding to areas of retinal wh...

“…Initially, all feeder arterioles are treated, followed by treatment of the draining venules with less intensity. Some com plications, including VH, rupture of Bruch's membrane, choroidal hemorrhage and ischemia, retinal tears and choroidal neovasculari zation, can occur (60,68,69,71,72) . The photocoagulation technique currently used (74) consists of sectorial treatment of the SF.…”

Hemoglobinopathies are a group of inherited disorders characterized by quanti tative or qualitative malformations of hemoglobin (Hb). Some of these diseases present vasoocclusive phenomena that are responsible for high morbidity in clinical and/or ophthalmologic terms. Diagnosis of hemoglobinopathies is perfor med exclusively through hemoglobin electrophoresis. From the ophthalmologic perspective, the most important representative of this group of diseases is sickle cell retinopathy, which presents a wide spectrum of fundus manifestations and may even lead to irreversible vision loss if not properly diagnosed and treated. The aim of this review is to present the classification of sickle cell retinopathy and to describe current management and future perspectives for its treatment, taking into consideration the clinical management of these patients.
