Correction of Senile Entropion by Full Thickness Lid Excision

Senile entropion remains something of an enigma, with no general agreement as to etiology or best surgical treatment. Little basic research on the problem of senile entropion had been carried out until Dalgleish and Smith inserted metal markers into the various anatomical layers of the lower lid and took lateral rediographs. As the results of their investigations, they showed that surgical intervention should be directed towards the correction of two important features in the etiology of senile entropion-rotation of the tarsal plate and loss of attach ment of skin and orbicularis to the deeper tissues. O'Donoghue and Roden reported that they could be corrected by excising a full-thickness triangle, apex up, from the central part of the lower lid. Three cases of senile entropion and one vase of spastic entropion were treated with the same procedure as O'Donoghue and Roden did except the excision of the redundant skin along the lowere lid margin. The results of our procedure was simple and successful.

Computed Tomographic Measurments of the Orbit and Proptosis in Koreans

The orbit has roughly the shape of a quadrilateral pyramid whose base corresponds to the orbital margin, and whose apex is the bar of bone between the optic foramen and the medial end of the superior orbital fissure. The orbital dimensions can be measured by plain X-ray or computed tomography. Plain X-ray of the orbit may be difficult for the non-radiologist to identify the measurement landmarks and interpret, whereas computed tomography allows more precise analysis by imaging soft tissue relationships to surrounding orbital bones. Measurement of the orbital dimensions and proptosis using CT does not only contribute to the diagnosis of specific pathologic processes, but also guide the ophthalmologist in planning appropriate medical and surgical management. One hundred and three orbital CT films of Korean adults were measured. The results were as follows: The average orbital width was 38.09 +/- 2.82mm, orbital height was 35.47 +/- 2.28mm, orbital index was 93.80 +/- 6.70, orbital depth was 42.67 +/- 3.56mm, interorbital distance was 24.97 +/- 2.25mm, extraorbital distance was 97.38 +/- 5.14mm and proptosis was 14.28 +/- 3.49mm.

Electron Microscopic Features of Epiretinal Membrane in Rhegmatogenous Retinal Detachment

Epiretinal membrane formation and membrane contraction are major complications in a variety of ocular conditions, including retinal detachment and penetrating ocular injuries. The epiretinal membrane was derived from pigment epithelial cell and glial cell. In rhegmatogenous retinal detachment, the retinal pigment epithelium was capable of proliferating through retinal tear into the vitreous contributing to preretinal membranes. In this study, we report the ultrastructural features of epiretinal membrane in rhegmatogenous retinal detachment removed during vitreous surgery from 4 patients.
