Eye contact is a powerful social stimulus for human and non-human primates. However, it is unclear whether brain mechanisms that interpret eye contact are sensitive to gender. Here we show that human brain responses to eye contact are indeed gender specific. Recording event-related potentials directly from the medial temporal lobes, we found that eye contact elicited specific responses in men only when they saw female faces. Conversely, women responded specifically to eye contact only when they saw pictures of men. Thus, the human medial temporal lobes subserve specifically the processing of eye contact with persons of the opposite gender.

Purpose: This study compares and evaluates the parameters of iridotrabecular contact (ITC) in patients with primary angle closure disease (PACD) with natural lenses and pseudophakia based on anterior segment imaging data from swept-source optical coherence tomography (SS-OCT).
Material And Methods: This retrospective study analyzed data from 92 patients aged 32 to 89 years, and included 56 patients with PACD (43 with natural lenses and 13 with pseudophakia) and 36 in the control group (21 with natural lenses and 15 with pseudophakia). All participants underwent SS-OCT (CASIA2; Tomey Corporation, Japan), which included an assessment of the ITC Index and ITC Area.

Purpose: To evaluate early response of retinal sensitivity (RS) and retinal morphology in diabetic macular edema (DME) patients after intravitreal anti-vascular endothelial growth factor (anti-VEGF) treatment.
Methods: Sixteen eyes of 12 DME patients were included in this study conducted prospectively. All eyes underwent functional and morphologic examination of the macular area using microperimetry and optical coherence tomography (OCT) before and after intravitreal anti-VEGF injection.

Purpose: To study change in the contact of intraocular lens (IOL) with the posterior capsule with respect to the vertical versus horizontal orientation of the haptic-optic junction of the IOL using intraoperative spectral domain optical coherence tomography (SD-OCT).
Methods: Fifty eyes of 50 patients with senile immature cataract underwent topical phacoemulsification procedure with implantation of a monofocal IOL by a single experienced surgeon. The Rescan 700 SD-OCT system was used for intraoperative imaging.
Blepharoptosis Associated With the Wearing of Hard Contact Lenses in Keratoconic Eyes.

Ophthalmology, International University of Health and Welfare, Chiba, JPN.
Keratoconus is a condition that causes progressive thinning and anterior protrusion of the cornea. Because of its irregular astigmatism, mild to moderate keratoconus is corrected with hard contact lenses (HCLs), but blepharoptosis due to the long-term wearing of HCLs is often a problem. In this study, we investigated blepharoptosis in HCL wearers with keratoconus.
