Treatment of iris melanoma by photocoagulation: a case report.

A 13-year-old white male was found to have a melanoma of the iris. Three treatments with xenon arc photocoagulation resulted in regression of the lesion with development of an iris coloboma. There were no complications, and corrected visual acuity has remained at 20/15 after a 19-year follow-up.

Clinicopathologic report of successful cobalt 60 plaque therapy for choroidal melanoma.

A 66-year-old man had malignant melanoma of the choroid that enlarged during a two-year period while a retinal detachment developed. Treatment consisted of a cobalt 60 plaque placed to deliver a dose of 35,000 rads to the base and 9,000 rads to the apex of the tumor. Clinical response was excellent and complete regression occurred.

The effects of hard contact lenses on intraocular lens calculations.

Corneal alterations from hard contact lens wear can have significant effects on the results of intraocular lens (IOL) calculation and this should be kept in mind in those patients who are candidates for lens implantation. Seven patients were studied during and two weeks after hard contact lens wear, showing an average increase of +0.79 +/- 1.

Orbital leiomyosarcoma after radiation therapy for bilateral retinoblastoma.

Leiomyosarcoma rarely occurs in the orbit and is seldom encountered as a postirradiation sarcoma in any anatomic location. Three patients with bilateral retinoblastoma who had received radiation therapy are known to have orbital leiomyosarcoma develop in their third decade of life. The clinical and pathological data pertaining to two of these patients are given and discussed herein.

Autosomal dominant exudative vitreoretinopathy.

Eight family members had familial exudative vitreoretinopathy. They exhibited a variety of clinical stages of the disease process. Some clinical findings included retinal detachment, fibrovascular masses with dragged disc and macula, neovascular fronds and intraretinal deposits.

Intraocular foreign body removal by endoscopy.

Pars plana endoscopy was used to guide removal of a large nonmagnetic intraocular foreign body from an eye with corneal scarring and irregularity of such a degree the view through the operating microscope was not adequate to permit such surgery.

Intraocular endoscopic surgery.

We have successfully used a new small endoscope in posterior segment surgery in situations where the operating microscope or binocular indirect ophthalmoscope provided an inadequate view. In this series of 18 procedures, we preformed posterior vitrectomies, removed retained foreign bodies, and reattached persistent retinal detachments. The only major complication was a retinal detachment.

Endoscopic orbital surgery.

Orbital endoscopy is useful in managing various types of orbital problems. A hand-held endoscope can be used for simple procedures. Surgery and prolonged observation require a mounted endoscope.

Vitreous surgery as a supplement to anterior segment surgery.

Selected vitreous surgery techniques can provide effective and safe means of supplementing anterior segment surgery for correction or avoidance of many problems. In my experience, the guillotine or piston action vitrectomy instruments are more effective and safer than those which have a rotating or oscillating action. Pars plana vitreous surgery has added a new dimension to anterior segment surgery.

Vitreous surgery as a supplement to cataract surgery.

In a series of 357 cases, vitreous surgery instruments were employed via a pars plana approach for supplementation of cataract surgery. The most frequent use was for supplementation of primary cataract surgery, either to correct vitreous loss or for performance of posterior capsulectomy. Other frequent indications included secondary cataract ("after-cataract"), retro-implant membrane, and PHPV.

Bimanual phacoemulsification.

The technique of bimanual phacoemulsification utilizing a microsurgical spatula has been found very useful to me and to others who have learned this method.

Prophylactic photocoagulation of the fellow eye in exudative senile maculopathy. A preliminary report.

Information on the fate of the fellow eye in patients who have suffered loss of central vision in the first eye due to exudative senile maculopathy suggests that there is a high incidence of later loss of vision in the second eye due to the same disease process. It has been speculated that prophylactic photocoagulation of the macula in the fellow eye might have a protective effect. This is a preliminary report of a series of patients in which argon laser photocoagulation of the second eye has been performed.

The effect of calcium dobesilate on nonproliferative diabetic retinopathy: a controlled study.

Two independent, double-masked, controlled studies were made to evaluate the efficacy of calcium dobesilate for the treatment of nonproliferative diabetic retinopathy. Forty-two patients underwent a six-month crossover evaluation while receiving calcium dobesilate (750 mg per day) and placebo in random order. Thirty-six patients received calcium dobesilate (1,000 mg per day) or placebo for one year.

Prolonged hypotony following cataract extraction.

Hypotony after intracapsular cataract extraction was prolonged in 3 eyes because cyclodialysis clefts were inadvertently formed. One eye became normotensive with the topical application of corticosteroid; 2 required surgical intervention.

An endoscope for ophthalmology.

An endoscope with a 1.7-mm diameter shaft has unique properties of focus, magnification, and large field of view that make it useful for both orbital and intraocular surgery.

Ectopia lentis: management by combined lensectomy and vitrectomy.

A technique is presented for removal of subluxated or dislocated lenses (ectopia lentis), along with performance of vitrectomy. It is believed that this method permits avoidance or reduction of the hazards and complications of techniques used in the past.

An unusual case of congenital hypertrophy of the retinal pigment epithelium.

Photographic documentation of enlargement of congenital hypertrophy of the retinal pigment epithelium is shown in a 42-year-old white woman. No other reports of enlargement have been made and previous articles have stated that these lesions do not grow.

Idiopathic focal subretinal neovascularization.

In 20 patients idiopathic focal subretinal neovascularization was characterized by a solitary focus of subretinal neovascularization at or near the fovea, associated with serous or hemorrhagic detachment of the overlying and adjacent sensory retina, or both. Although the lesions resembled the neovascular membrane seen in the presumed ocular histoplasmosis syndrome, none of the other associated characteristic ophthalmoscopic findings, considered essential to make the latter diagnosis, were apparent. In this group of patients, the incidence of positive histoplasmin skin tests was no greater than in the general population.
