RESUMO
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.

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. The fundus and angiographic findings were found to be similar to those in cases reported previously. Electroretinograms were normal. Of particular interest in this pedigree was the sole clinical finding of isolated intraretinal deposits in four family members. This characteristic may represent a mild expression of the disease and warrant appropriate genetic counseling. Our study confirms the variable clinical expression of the disease.

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. Of the 20 patients, two had bilateral disease. In no case were there any other lesions of any kind in the afflicted or the opposite eye. The disease is self-limited over a variable period of time, but may result in extensive scarring with loss of central vision.

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 patient later died of an unrelated disease. Histopathologic study verified complete regression of the tumor.

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.

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. These two techniques provided good results in 15 patients. Endoscopy proved useful in finding and removing orbital foreign bodies. It is potentially useful in the management of orbital tumors, but experience in this area is still limited.

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. Learning to use a monocular system requires practice and preparation with experimental animals.

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. There is reason to hope that the future will bring further refinements of instrumentation and surgical technique and more precise knowledge of the indications and limitations of this type of surgery.
