Retinal surgery under the microscope.

In the case of small breaks, the operating microscope and slitlamp are of great help in retina detachment surgery. The use of an adequate peripheral fundus contact lens is necessary. The technique to be followed is described and its advantages and disadvantages are discussed.

Juvenile retinal vasculitis of the central variety.

Central retinal vasculitits of the type reported herein occurs monocularly in young males. The presenting symptom is always a massive vitreous hemorrhage with gross visual loss, which tends to persist indefinitely. Vitrectomy through the pars plana is followed by complete visual recovery; the condition becomes quiescent, although recurrent hemorrhages may occur. Other complications seen after surgery are glaucoma and retinal detachment. 6 cases were seen in a period of 11/2 years.

[Phakofragmentation and aspiration through the pars plana ciliaris (author's transl)].

Not until Machemer et al. started doing what they called posterior lensectomies with the vitreous-infusion-suction-cutter did removal of the lens through the pars plana become standard procedure. Effected originally as a first step in eyes undergoing vitrectomy, when an opaque lens interfered with fundus visibility, it has started to be used as an independant procedure in the case of soft-mostly traumatic-cataracts, and in that of ectopic or subluxated lenses. In 40 out of 43 operated cases the results have been as good as could be expected from the condition of the macula. Three cases, or 6.9%, developed serious complications: one a retinal detachment which could not be cured by surgery, one a chronic corneal edema, and one a secondary glaucoma which reacted poorly to medical therapy.
