ABSTRACT
The most important factor associated with the development of diabetic retinopathy is the duration of the diabetes. Studies to examine the relationship of diabetic retinopathy to plasma lipids and lipoproteins have produced conflicting results. We examined the association of background and proliferative retinopathy development with plasma lipid and lipoprotein changes in 78 patients with Type I diabetes. We found significant increases in plasma total cholesterol, low-density lipoprotein (LDL) cholesterol, LDL phospholipid, and high-density lipoprotein (HDL) cholesterol only in patients with proliferative retinopathy. The changes in plasma triglycerides, HDL phospholipid, and apolipoproteins A and B, were not significant. Furthermore, the duration of diabetes and patient age were correlated with both background and proliferative retinopathy.

Ultrasonography and computerized tomography (CT) of the painful and blind right eye of a 13-year-old girl showed a cystic mass almost filling the vitreous cavity and narrowing the anterior chamber. The histopathologic diagnosis of the enucleated eye was an echinococcus cyst. Abdominal ultrasonography, brain CT and chest X-rays gave no abnormal findings when first examined, nor during the follow-up 18 months after surgery. Indirect hemagglutination test was negative at the last control. The case was accepted as a primary hydatid cyst (echinococcosis) of the eyeball.

The threshold resistance to Nd:YAG laser irradiation of cross-linked lathe-cut PMMA intraocular lenses was slightly higher than that of Perspex CQ lenses: 6.0 mJ vs 4.5 mJ for single laser spots, and 3.5 mJ vs 3.0 mJ for four spots. These levels produced nicks and pits in the lenses; higher levels created small breaks.

Fibrin sealants were used in place of the classical suture materials in strabismus surgery. Classical recession operations were performed on the right eyes of ten albino rabbits, while the recessed anterior rectus muscles of the left eyes were fixed to the sclera with the tissue sealant. Better histopathological results were obtained with the fibrin sealant than with the classical sutures, but the functional results were worse.
