Significant association of asteroid hyalitis with other ocular diseases has beeri disclaimed by clinical (Rutherford, I933) and pathological (Rodman, Johnson, and Zimmerman, I 961) observation.The literature on retinal separation is so voluminous that oversight is possible, but a search of the literature over go years has revealed only three references (D'Oench, I889; Bailey, I926; Krejci, I963) to retinal separation associated with asteroid hyalitis.One of these patients (Bailey, I962) had diabetic retinopathy.Five patients from a group of 448 with clinical retinal separation had asteroid hyalitis.Three of them had retinal separation only in the eye with asteroid hyalitis and the other two had retinal separation in one eye and asteroid hyalitis in both.The association of these two diseases can present preoperative and operative difficulties. Case reportsCase I, a 67-year-old white man, had noticed poor vision in the right eye for 3 weeks.He had been diabetic for 2 years and the diabetes was controlled by diet and acetohexamide 500 mg.twice daily. ExaminationVisual acuity on admission to hospital was counting fingers at 6 in. in the right eye with -' 25 D sph., +2-75 D cyl., axis 1250, and 20/50 in the left eye with -o 300 D sph., +4-25 D cyl., axis 94°.Intraocular pressure was 30 mm.Hg in the right eye and 26 in the left by applanation.He had nuclear cataracts.The inferior temporal and inferior nasal retina was elevated, including the macula.A horseshoe tear was present just below the temporal long posterior ciliary nerve.Ophthalmoscopy was made difficult by asteroid hyalitis in the right eye. SurgeryOn November 3, I969, a local scleral buckling procedure closed the tear without release of subretinal fluid.Visual acuity improved to 20/200.Fluid re-accumulated inferiorly and no addtional tear could be found.At re-operation the local buckle was extended inferiorly with additional cryopexy and fluid release. ResultVisual acuity improved to 20/50.The intraocular pressure was controlled with i per cent.pilo- carpine.The disc: cup ratio was 8: i.Case 2, a 78-year-old white man, was admitted to hospital, having had poor vision in the left eye for 2 to 3 months.A past history of deafness, dermatitis, and heart disease was present for which he took prednisone, benadryl, and digitoxin.
