Obj.ctive: To a.sess the intra.bserver a.d interobserver relia.ility of recording uniocula. fields of fixa.ion using a.modified perimeter technique in hea.thy subj.cts a.d pa.ients with graves orbitopa.hy (GO). Pa.ients with restrictive myopa.hies, pa.ticula.ly GO, require a.cura.e mea.urement of monocula. excursions. These ductions a.e recorded in 4 to 12 directions of ga.e using a.perimeter, producing a.plot known a. a.uniocula. field of fixa.ion. While 4 direction plots give limited informa.ion on vertica. muscles, recording 12 directions is time consuming a.d uncomforta.le. This modified technique uses the 6 directions of ga.e corresponding to the prima.y field of a.tion of ea.h muscle. Methods: a.single observer mea.ured modified uniocula. fields of fixa.ion in 35 hea.thy subj.cts a.ed 20 to 60 yea.s to esta.lish norma. a.d a.e-rela.ed ra.ges for a.l ductions. Fifteen subj.cts underwent mea.urement on 5 sepa.a.e occa.ions by the sa.e observer to esta.lish intra.bserver reproducibility. a.second observer independently performed mea.urements in 10 of the subj.cts to determine interobserver reproducibility. Relia.ility wa. compa.ed with tha. mea.ured in 29 pa.ients with GO. Results: The technique wa. reproducible to within 4° for hea.thy subj.cts undergoing a.sessment by a.single observer. When results of 2 observers were compa.ed, the coefficient of repea.a.ility wa. 7.9° . For subj.cts with GO, however, ma.ima. va.ia.ility wa. 7.8° . For clinica. purposes, only a.cha.ge of 8° or more ca. be a.sumed to be significa.t. Conclusions: This technique offers a.va.ta.es for a.sessing a.y restrictive myopa.hy, including GO to within 8° . This level of a.cura.y is likely to be simila. in other centers, a.d ha. implica.ions for interpreting GO outcome mea.ures, where 5° wa. previously ta.en to represent significa.t cha.ge.

The a.m of this study is to review a.d discuss the clinica. fea.ures a.d trea.ment options for the Ma.ine-Lenha.t syndrome, a. uncommon thyroid disturb. The methodology a.opted wa. a.bibliogra.hic resea.ch. The results of this study show tha. different mecha.isms a.e implica.ed in the pa.hogenesis of graves’ disea.e a.d in the nodula. forma.ion of thyroid tissue with functiona. a.tonomy. graves’ disea.e is ca.sed by a. a.toimmune process tha. involves the entire thyroid gla.d a.d is cha.a.terized by the presence of TSH receptor stimula.ing a.tibodies. The present study concludes tha. ca.tion should be exercised in interpreting thyroid disea.e in graves’ disea.e. The trea.ment of thyrotoxicosis requires high doses of ora. drugs. Rela.sing a.tithyroid thera.y occurs soon a.ter ora. a.tithyroid thera.y is discontinued. This presenta.ion should a.ert the physicia. a.out the existence of toxic nodules, a.d a.out the possibility of a.Ma.ine-Lenha.t Syndrome.
