The authors report a recent complication during the postoperative period of cataract surgery. A patient was submitted to cataract surgery in both eyes with IOL implantation (Sensar) inside the capsular bag. The postoperative period of right eye was uneventful, however, in the left eye the patient noted a dark shadow at the temporal visual field at the first postoperative week. This diagnosis was confirmed with the presence of a temporal scotoma revealed by the computerized visual field (first reported in this study) and also reducing the pupil area with miotic drops. The treatment of this complication was performed by using brimonidine tartrate and after 6 months this symptom completely disappeared as confirmed by the computerized visual field. The treatment should be based on reducing the pupil area with miotic drops and we also recommend to observe these cases until the 6th postoperative month before indicating an IOL exchange since the capsular edge that overlaps the IOL may opacify creating an optical barrier reducing or eliminating negative dysphotopsia.

Tachistoscopic studies have established a right field advantage for the perception of visually presented words, which has been interpreted as reflecting a left hemispheric specialization. However, it is not clear whether this is driven by the linguistic task of word processing, or also occurs when processing properties such as the style and regularity of text. We had 23 subjects perform a tachistoscopic study while they viewed five-letter words in either computer font or handwriting.

Introduction: Tear exchange during contact lens wear is essential for ocular surface integrity, facilitating debris removal, and maintaining corneal metabolism. Fluorophotometry and fluorogram methods are typically used to measure tear exchange, which require hardware modifications to a slit lamp biomicroscope. This manuscript introduces an alternative method using a corneoscleral profilometer, the Eye Surface Profiler (ESP), to quantify tear exchange during corneal and scleral rigid lens wear by assessing fluorescence intensity changes over time.

Background/ Aims: To analyze the longitudinal change in Bruch's membrane opening minimal rim width (BMO-MRW) and peripapillary retinal nerve fiber layer (pRNFL) thickness using optical coherence tomography (OCT) after implantation of a PRESERFLO® microshunt for surgical glaucoma management in adult glaucoma patients.
Methods: Retrospective data analysis of 59 eyes of 59 participants undergoing implantation of a PRESERFLO microshunt between 2019 and 2022 at a tertiary center for glaucoma management. Surgical management included primary temporary occlusion of the glaucoma shunt to prevent early hypotony.

Retinal image registration is vital for diagnostic therapeutic applications within the field of ophthalmology. Existing public datasets, focusing on adult retinal pathologies with high-quality images, have limited number of image pairs and neglect clinical challenges. To address this gap, we introduce COph100, a novel and challenging dataset known as the Comprehensive Ophthalmology Retinal Image Registration dataset for infants with a wide range of image quality issues constituting the public "RIDIRP" database.
