ALTHOUGH the Millipore filtration technique of cytological analysis has been largely neglected in clinical ophthalmology (Goldberg, Erozan, Duke, and Frost, 1965; Jarrett, Goldberg, and Schulze, 1966), it can be of practical assistance in diagnosis and therapy. Documentation of this usefulness is provided by the following report of morgagnian cataract with phacolytic glaucoma.
Case ReportAn 88-year-old man of Ukrainian descent complained of decreasing vision of 20 years' duration.Vision had painlessly and progressively decreased in the right eye until 8 years before admission, when he had been struck in the right eye with a tree branch and sustained a laceration of the upper lid. Subsequently, there was further decrease in vision of the right eye. One week before admission, redness and mild pain were noted and topical corticosteroids were instituted by the patient's general practitioner. On the day of admission the patient's niece had discovered that the right cornea appeared to be white and opaque.Examination.-The visual acuity was perception of light with good projection in the right eye and 20/60 (with -0-5D sph.) in the left. Except for early nuclear sclerosis of the lens, the left eye was normal.On the right the conjunctiva was moderately and diffusely hyperaemic without discharge. The cornea had a cloudy white appearance, through which the pupil was barely discernible. Biomicroscopical examination showed oedema of the corneal epithelium, a normal stroma, and no keratic precipitates. The anterior chamber was of normal depth but was completely filled with milky material containing myriads of tiny, iridescent, pin-point particles. The anterior chamber angle could not be visualized with a gonioprism. No details of the iris were visible. After the instillation of glycerine drops, biomicroscopy revealed a barely visible iridescent cataract. A pinkishwhite fundus reflex was obtained.The intra-ocular pressure was 43 4 mm. Hg (Schiotz) in the right eye and 14-6 mm. Hg (Schiotz) in the left.A clinical diagnosis of severe iritis was made; other possibilities included necrotic intra-ocular neoplasm, retained intra-ocular foreign body, metastatic endophthalmitis, glaucomatocyclitic crisis of Posner-Schlossman, and lens-induced glaucoma. The patient was treated with a systemic carbonic anhydrase inhibitor and topical l-epinephrine, atrophine, and phenylephrine without relief. Systemic penicillin and chloramphenicol were started on the following day, and hourly CortisporinR eye drops were added to the therapeutic regimen. In the next 3 days there was no appreciable change.
