1.Results of Reconstruction of Orbital Wall Fracture With Bioresorbable Plate.
Journal of the Korean Ophthalmological Society 2009;50(12):1761-1767
PURPOSE: To investigate the long-term results and complications of orbital wall fracture reconstruction using the bioabsorbable orbital implant, Macropore(R) orbital floor liner. METHODS: This retrospective study included patients who underwent the reconstruction of an orbital wall fracture using Macropore(R) orbital floor liner and completed a postoperative follow-up longer than 6 months. The enophthalmic values as well as the data of ocular movement and diplopia was collected from the medical records of each patient and analyzed. RESULTS: A total of 35 patients were evaluated with an average follow-up period of 14.0 months. The average enophthalmic value of 29 patients, whose reconstruction was primarily indicated from enophthalmic tissue, was 0.90 mm at the last follow-up. No significant progression of enophthalmos was observed at postoperative 12, 18 and 24 months when compared with the enophthalmic value at postoperative 6 months. All 15 patients who have had the limitation of ocular movement or diplopia preoperatively resolved completely or improved to the degree that no clinically significant limitation or diplopia further existed. No complications such as dislocation of implant, infection, and aggravation of ocular limitation were observed during the follow-up period. CONCLUSIONS: Macropore(R) orbital floor liner may be regarded as a useful implant in reconstruction of orbital wall fracture with no significant implant-related complications during its absorption.

PURPOSE: In this study we compared the surface wettability of ocular prosthesis and depositions depending on different types of artificial tear eye drops. METHODS: The artificial tear eye drops contain sodium hyaluronate (HA) 0.1%, 0.18%, 0.3%, carboxylmethylcellulose sodium (CMC), hydroxymethylcelluose + dextran (HMC), propylene glycol + polyethylene glycol (PG), polysorbate 80 (PS) povidone (Pov) were evaluated. Flat rectangular parallelepiped blocks consisting of polymethylmethacrylate (PMMA) or silicone materials were made. One artificial tear eye drop was applied on the surface of two different blocks of artificial eyes using a 23-gauge needle. Then, the static method contact angle was measured by using a contact angle goniometer. To measure the deposits, a petri dish was covered with 3 mL of artificial tear eye drops and dried for 48 hours at room temperature. Then, the light transmittance at the center of the petri dish was measured to investigate the amount of the residue. RESULTS: The contact angles of HA 0.1%, 0.18%, 0.3%, CMC, HMC, PG, PS and Pov on PMMA were 78.69degrees, 84.29degrees, 75.46degrees, 80.93degrees, 66.29degrees, 71.26degrees, 58.40degrees and 70.24degrees, respectively. The contact angles on silicone were 53.68degrees, 60.87degrees, 64.46degrees, 62.78degrees, 38.89degrees, 63.58degrees, 30.68degrees and 51.41degrees, respectively. The largest decrease in transparency was observed in the artificial tear eye drops containing HMC. CONCLUSIONS: The wettability and deposits on the surface of ocular prosthesis can vary based on the components and concentration of artificial tear eye drops. The results from this study should be considered when choosing the right artificial tear eye drops for improving dry eye symptoms in patients wearing ocular prostheses.

Kearns-Sayre syndrome, first described by Kearns and Sayre in 1958, is a rare disorder consisting of ptosis, limited movement of both eyes and atypical retinal pigmentary change (salt-pepper like appearance). Most cases have shown an increase in the concentration of mitochondria and ragged-red fiber under Gomori-trichrome staining on muscle biopsy. Occasionally, it is combined with other neurologic and endocrinologic symptoms such as ataxia, dementia, diabetes, and hyperaldosteronism. We recently experienced three cases of male teenaged patients who expressed the clinical features of Kearns-Sayre syndrome.
