Fixation disparities (FD) were measured as a function of forced vergence using binocular scleral search coils and simultaneously with nonius lines. The slope of the objective FD curve was significantly greater than the subjective FD curve for three of five subjects. This indicates an alteration in retinal correspondence of up to one degree, that shifts Panum's area to avoid the diplopia normall...

BACKGROUND To report a case of impending extrusion of Ex-PRESS shunt treated by shunt-position adjustment. CASE PRESENTATION A 56-year-old Asian woman presented with impending extrusion and malposition of Ex-PRESS shunt in her left eye. The bleb of the left eye was shallow and diffuse. In the past, the patient was treated by Ex-PRESS shunt implantation under the scleral flap in both eyes. The...

Post-traumatic aniridia combined with aphakia may be seen after globe injury. Aside from esthetic aspects, partial or total loss of the iris tissue may also be related to various degrees of glare and photophobia. Such patients suffer from severe visual impairment secondary to aphakia. Herein we describe a novel surgical technique for the management of an aphakic eye with traumatic aniridia for ...

BACKGROUND Suture exposure remains to be a potential problem of transscleral fixated posterior chamber intraocular lens (PCIOL). We report a modified technique to minimize the risk of suture exposure for the transscleral fixation of PCIOL. METHODS The modified surgical technique is as following: at first, two 3 mm × 4 mm square scleral pockets were created from groove incisions at opposite po...

Several techniques have been employed for repositioning dislocated intraocular lenses (IOLs). Herein, we describe a simplified and modified technique in which scleral fixation is performed together with temporary externalization of IOL haptics through a small, superior clear corneal incision. The sutures are tied to the externalized haptics; the haptics are then repositioned into the anterior c...

PURPOSE To report a case of bilateral spontaneous anterior lens dislocation associated with retinitis pigmentosa (RP). METHODS A 45-year-old male with RP presented with elevated intraocular pressure (IOP) in the right eye and was treated with laser iridotomy (LI). After LI, complete crystalline lens dislocation into the anterior chamber occurred. Surgical intervention, including anterior vitr...

A 83-year-old woman underwent phacoemulsification in the left eye, complicated by posterior capsular rupture and dislocation of nuclear fragments vitreous cavity. She was aphakic referred to Clinica Oculistica, Azienda Sanitaria Universitaria Friuli Centrale, Udine, Italy. After 2 days, she pars plana vitrectomy, with removal fragments, secondary intraocular lens (IOL) implantation. The used a ...

Two human subjects, who had no signs of other neurologic disorders, produced large amplitude, to-and-fro saccadic oscillations. One subject generated these oscillations intentionally. Eye movement recordings by DC electro-oculography and/or magnetic scleral search coil showed that the movements were bursts of conjugate saccades in opposing directions with no intersaccadic intervals. They were m...
