Subretinal neovascularization in children and adolescents.

Subretinal neovascular membranes (SRNVM) in the pediatric population are rare. The clinical presentation, etiology, course, and management of SRNVM in 25 children (27 eyes) were studied retrospectively. Inflammatory or infectious conditions predominated (10 of 25).

Pasteurella multocida endophthalmitis.

We have recently seen an unusual case of endophthalmitis secondary to Pasteurella multocida infection. Unlike previously reported cases this patient had no previous history of animal bites or scratch wounds. Treatment included subconjunctival, parenteral, and intravitreal administration of ampicillin.

Management of giant retinal tears without scleral buckling.

Giant retinal tears have been repaired in six consecutive patients without the use of a scleral buckle. By using preoperative laser photocoagulation, pars plana vitrectomy with light choroidal cryopexy, pure C3F8 gas injection followed by postoperative positioning and supplemental laser, excellent anatomic and visual results have been achieved. The risk of proliferative vitreoretinopathy may be minimized using this technique.

Meandering ocular toxocariasis.

Ocular toxocariasis affects the eye in three recognizable patterns: a peripheral inflammatory mass in a quiet eye, posterior pole granuloma, or painless endophthalmitis. The present case photographically documents a new form of ocular involvement, that of periodic intraretinal meandering, followed by quiescence with encapsulation, reemergence, and renewed migration. The similar behavior of the Toxocara canis larva in the animal model and the serologic confirmation of Toxocara canis by ELISA testing establishes the diagnosis in the present case.

Retinal pigment epithelial tears.

Retinal pigment epithelial tears have been recognized recently as a complication of retinal pigment epithelial detachments. They are characterized by sudden separation of detached from attached pigment epithelium at the margin of the detachment. Retraction of the overlying pigment epithelium occurs and exposes Bruch's membrane and choroid.

Incidence of fluorescein angiographic subclinical macular edema following phacoemulsification of senile cataracts.

Fluorescein angiograms were performed in 90 patients the first and sixth week after removal of non-traumatic cataracts by phacoemulsification. The incidence of macular edema was found to be one half that reported in the literature for a comparable group of patients following intracapsular cataract extraction. The difference in incidence of macular edema between the phacoemulsification and the intracapsular groups seems dependent on the presence of the posterior capsule and perhaps the small size of the phacoincision.

Retinal detachment following congenital cataract surgery.

It is hoped that the results of surgery for retinal detachment after surgery for congenital cataract, when discission and aspiration or phacoemulsification under the microscope are used, will approach the present reattachment rate that has been achieved with improved examination, instrumentation, and surgical technique in cases of senile retinal detachment. Further studies of the role of retinal pathology as lattice degeneration, vitreous pathology, and the place for prophylactic cryotherapy all must be reevaluated. In summary, the low incidence of retinal detachment following the extraction of congenital cataracts as seen in major retinal referral centers suggests that the risks of detachment are not as high as previously reported, that the cure rate approaches that of senile aphakic detachment; therefore early operative intervention to prevent amblyopia, nystagmus, and strabismus is indicated.

Retinal detachment following cataract extraction by phacoemulsification.

A review of 1,107 cases of cataract extraction by phacoemulsification is presented. The incidence of retinal detachment in this group was found to be 1,7%. This incidence of retinal detachment following phacoemulsification appears to be favorable compared to that following conventional cataract extraction.

Vitelliform dystrophy in a 64-year-old man.

A 64-year-old white man had many large bilateral vitelliform-like lesions. A normal electroretinogram, abnormal elector-oculogram, and a pattern of blocked choroidal fluorescence were obtained. The yellowish appearance of the lesions progressed to absorption of yellow material and mottling with maintenance of relatively good visual acuity.

Traumatic central retinal artery occlusion with sickle cell trait.

An 8-year-old black boy with sickle cell trait struck his left brow and globe on the edge of a table and had immediate blurring of vision. Six days later visual acuity was light projection, and traumatic iritis with secondary glaucoma and perimacular edema were present. Fluorescein angiography indicated obstructed peripheral and perimacular arterioles and dye leakage from the disk.
