The effect of lid closure and opening upon the ocular temperature gradient was studied in the rabbit eye by determining the changes in temperature of the anterior surface of the central cornea, the pupillary area of the anterior chamber, and the midiris area of the posterior chamber. With lid closure the temperature of all three areas rose to a similar level of 37.7° C. so that the ocular tempe...

PURPOSE To evaluate whether dry-eye symptoms are associated with epitheliopathy of that portion of the upper eyelid marginal conjunctiva-the lid wiper-that wipes the ocular, or contact lens surface, during blinking. METHODS Subjects were divided into two groups based on the presence or absence of dry-eye symptoms. The lid wiper of asymptomatic (n=75) and symptomatic (n=30) soft contact lens w...

Although Merkel cell carcinoma of the eye lid is reported frequently in the literature, only limited information exists about the distribution of Merkel cells in this tissue. Therefore, serial sections of 18 human cadaver eye lids (donors ages ranging between 63 and 97 years) were stained for cytokeratin 20 in various planes. The overall appearance of Merkel cells in these samples was low and m...

We have hypothesized previously that evaporation from the tears generates a solute gradient across the tear meniscus, which delivers hyperosmolar stress to the mucocutaneous junction (MCJ) of the lid margin. This is proposed as the basis for Marx's line, a line of staining with topically applied dyes that lies directly behind the MCJ. In this article, we consider the implications of this hypoth...

purpose : we describe clinical and radiologic findings and surgical outcome of an orbital dermoid cyst located in the superior oblique muscle tendon. this unusual location for dermoid tumors has not been reported previously. case report : a 15-year-old girl referred to us with an orbital mass in superonasal quadrant of the left orbit reportedly to be present from birth. computed tomography reve...

BACKGROUND Three principal techniques exist with which to create the Asian double eyelid: the suture, partial-incision, and full-incision methods. The partial-incision method is reliable and long-lasting without many of the drawbacks of the full-incision method. OBJECTIVE The surgical technique of the partial-incision method is reviewed in a stepwise fashion so that the reader can reproduce t...

BACKGROUND Ocular manifestations of thyroid dysfunction constitute a wide clinical spectrum ranging from minor ocular discomfort, lid retraction, lid lag and ocular injection, to sight threatening eyeball protusion and optic nerve compression. Thyroid-related eye disorders are most commonly associated with Graves' disease, and this most frequently occurs in the setting of hyperthyroidism. Howev...

DESCRIPTION A 13-month-old Caucasian female presented with erythema, swelling, and pain of the left periorbital region. On admission, her vital signs were normal, and complete blood count did not reveal abnormalities. Blood and eye cultures were collected. On physical examination, the left eye was erythematous and edematous starting at the left medial canthus, tracking across the upper lid to t...

Domestic chicks reared under continuous light developed light-induced avian glaucoma (LIAG), including eye enlargement and flat cornea. Chicks reared under dim light developed dim light buphthalmos (DLB), a somewhat similar eye enlargement, superimposed on the LIAG effect when, as in one subgroup of the present experiments, the dim light was also continuous. Unilateral lid suture elicited exper...

OBJECTIVE To study the basic eyelid and orbital measurement in the four main ethnic groups of southern Thailand. MATERIAL AND METHOD The basic eyelid and orbital surface anatomy of 101 normal subjects aged 20-40 years old were measured in the four ethnic groups of which the majority of people in southern Thailand belong to: Thai, Chinese, Thai-Malay, and Thai-Chinese. RESULTS Of the 101 sub...
