Abstract
PURPOSE To compare the refractive power profile, subjective depth-of-field and objective optical quality of two advanced monofocal intraocular lenses (IOLs) designed to improve intermediate vision. METHODS This prospective study evaluated forty-six eyes of twenty-three patients, aged 54-68 years, binocularly implanted with two monofocal enhanced intraocular lenses (IOLs), the Tecnis Eyhance and the Physiol Isopure. Subjective through-focus visual acuity curves were obtained by placing trial lenses in front of the eye while wearing its best spherical-cylindrical correction for distance. Objective optical quality was defined as the area under the modulation transfer function, calculated from the wavefront maps measured with a high-resolution aberrometer. The optical design of both lenses was compared based on their refractive power profiles measured with the lenses immersed in saline solution. RESULTS Both lenses have progressive aspherical geometries, in which the sagittal power decreases rapidly from the center to the edge of the optical zone. Mean monocular through-focus curves show a best corrected distance visual acuity of - 0.02 logMAR with both lenses. Through-focus visual acuity was marginally higher for the Eyhance, with a difference of 1 letter at the defocus position of - 0.5D and 3 letters between - 1.0D and - 2.0D. Objective assessment of optical quality revealed only a difference of about 2 points in MTF area at distance. CONCLUSION Both IOLs use a similar approach to improve intermediate vision. The Eyhance showed marginally better subjective performance than the Isopure at the target vergences between - 1.00D and - 2.00D, although these results did not reach statistical significance and were not replicated by the objective findings.

Abstract
BACKGROUND Meibomian gland dysfunction (MGD) is one of the most common conditions in ophthalmic practice and the most frequent cause of evaporative dry eye disease (DED). However, the immune mechanisms leading to this pathology are not fully understood and the diagnostic tests available are limited. Here, we used the nCounter technology to analyze immune gene expression in DED-MGD that can be used for developing diagnostic signatures for DED. METHODS Conjunctival cell samples were obtained by aspiration from patients with DED-MGD (n = 27) and asymptomatic controls (n = 22). RNA was purified, converted to cDNA, preamplified and analyzed using the Gene Expression Human Immune V2 panel (NanoString), which includes 579 target and 15 housekeeping genes. A machine learning (ML) algorithm was applied to design a signature associated with DED-MGD. RESULTS Forty-five immune genes were found upregulated in DED-MGD vs. controls, involved in eight signaling pathways, IFN I/II, MHC class I/II, immunometabolism, B cell receptor, T Cell receptor, and T helper-17 (Th-17) differentiation. Additionally, statistically significant correlations were found between 31 genes and clinical characteristics of the disease such as lid margin or tear osmolarity (Pearson's r < 0.05). ML analysis using a recursive feature elimination (RFE) algorithm selected a 4-gene mRNA signature that discriminated DED-MGD from control samples with an area under the ROC curve (AUC ROC) of 0.86 and an accuracy of 77.5%. CONCLUSIONS Multiplexed mRNA analysis of conjunctival cells can be used to analyze immune gene expression patterns in patients with DED-MGD and to generate diagnostic signatures.

Abstract
PURPOSE To investigate the clinical validity of using wavefront measurements obtained with a recently available pyramidal aberrometer to assess the optical quality of eyes implanted with diffractive intraocular lenses (IOLs). METHODS Individual biometric data were used to create models of pseudophakic eyes implanted with two diffractive IOLs. Their synthetic wavefronts were calculated by ray-tracing with near infrared wavelength (0.85 μm). Comparisons of the through-focus visual acuity of 12 pseudophakic eyes were obtained with three different methods: clinical defocus curves; simulated defocus curves calculated from ray-tracing in the customized model eyes; and through-focus simulated defocus curves calculated from the wavefront data measured with a pyramidal aberrometer. RESULTS Image quality calculated from wavefront data obtained by ray-tracing with 0.85 μm wavelength, without scaling the phase to 0.55 μm, resulted in a significantly different through-focus curve compared to the reference values. Even so, after scaling of the wavefront data to 0.55 μm, the defocus curves calculated from the wavefronts measured with the pyramidal aberrometer did not match the shape and the depth of field of the clinical defocus curves or the theoretical expected values. CONCLUSIONS Correcting for the longitudinal chromatic aberration of the eye when measuring the wavefront of eyes implanted with diffractive IOLs under near infrared light only accounts for the best focus shift due to the longitudinal chromatic aberration, but not for the wavelength dependence of the diffractive element. The pyramidal sensor does not seem to properly sample the slopes of a wavefront measured from a pseudophakic eye implanted with a presbyopia-correcting diffractive IOL to a clinically acceptable level.

Abstract
PURPOSE This study reports visual health during the COVID-19 pandemic in 2021 in Spain and Portugal, focusing on eye complaints and population habits. MATERIAL AND METHODS Cross-sectional survey through an online email invitation to patients attending ophthalmology clinics in Spain and Portugal from September to November 2021. Around 3833 participants offered valid anonymous responses in a questionnaire. RESULTS Sixty percent of respondents identified significant discomfort related to dry eye symptoms for increased screen time and lens fogging using facemasks. 81.6% of the participants used digital devices for more than 3 h per day and 40% for more than 8 h. In addition, 44% of participants referred to worsening near vision. The most frequent ametropias were myopia (40.2%) and astigmatism (36.7%). Parents considered eyesight the most important aspect of their children (87.2%). CONCLUSIONS The results show the challenges for eye practices during the initial COVID-19 pandemic. Focusing on signs and symptoms that lead to ophthalmologic conditions is an essential concern, especially in our digital society highly dependent on vision. At the same time, the excessive use of digital devices during this pandemic has aggravated dry eye and myopia.

Abstract
PURPOSE This study aims to estimate the efficacy and safety of a new intense pulsed light (IPL) Thermaeye Plus for dry eye disease (DED) secondary to meibomian gland dysfunction (MGD). PATIENTS AND METHODS This is a prospective, longitudinal study of patients with moderate to severe MGD. Treatment consisted of 4 consecutive IPL sessions, 12 flashes with the same energy 8J/cm2 on the periocular area at days 1, 14, 28, and 49. All patients were evaluated before each IPL sessions and 1 and 4 months after the last session. Measuring: Symptoms score and OSDI questionnaire, Non-invasive tear meniscus height (NITMH), Non-invasive break up (NITBUT), Tear osmolarity (TO), Corneal fluorescein staining (CFS) and Eyelid margin and Meibomian gland assessment. The adverse effects on the eye, periocular area, and systemic complications were evaluated. All types of skin pigmentation (Fitzpatrick scale I to VI) were included. RESULTS The study included 44 consecutive patients (88 eyes), 40 males and 48 females, with a mean age of 52.5±13.6 years, ranging from 22 to 78 years. Significant improvements were observed in single and total signs and symptoms. The most significant changes were observed in dryness, foreign body sensation (p<0.001), and pain (p<0.005). The OSDI questionnaire showed a significant decrease in total symptoms (p<0.003). The percentage of patients with a normal index <13, improved from 23.8% (10 patients) at baseline to 80.9% (34 patients) at last visit, after 23 weeks. Clinical sings also improved, more than 90%, stand out telangiectasia and blepharitis (p<0.002, and p<0.0005, respectively). No statistical differences between age (<40y, 40-60y, and >60y) and gender were observed. The clinical improvement began after the second and third week after the first IPL session, until the end of the IPL treatment (D49). After that, the results maintained stable until the last visit, after 11 weeks. No complications were reported locally, nor in the periocular area as well as systemically. CONCLUSION Thermaeye Plus, a new IPL for ophthalmic use, is a safe and effective treatment in patients with DED due to MGD, showing improvement from the second week of treatment and maintaining until the last visit, 4 months after the last IPL session (23 weeks of total follow-up). Patients with pigmented skin (Fitzpatrick V or VI) have been treated with no side effects. It is relevant, especially to apply in brown-dark skin populations since complications with other IPL devices have been reported.

Abstract
Ocular abnormalities such as corneal opacities and some specific alterations in ocular movements have been described in the neuropathic forms of Gaucher disease. This study was designed to correlate the clinical, morphological and biochemical findings in the corneal button obtained after keratoplasty in a Gaucher disease carrier with keratoconus. Morphologically, the cornea showed keratocytes with marked dilatations of the rough endoplasmic reticulum and intracytoplasmic "dark inclusions"; the acidic lipid profiles presented alterations in the cornea of the Gaucher disease carrier when compared with healthy controls and a clear deficiency in beta-glucosidase activity was detected as well. Our data suggest that the cornea may serve as a good marker of an early target organ in lipid metabolism disorders such as Gaucher's disease.

Abstract
PURPOSE To evaluate and compare the topographic and topometric parameters, thickness profile data, and data from enhanced elevation maps of thin non-keratoconic, subclinical keratoconic, and mild keratoconic corneas with the Pentacam Scheimpflug corneal tomography and to study the usefulness of different parameters to differentiate keratoconus from topographically normal thin corneas. METHODS The study included 30 eyes with subclinical keratoconus, 30 eyes with mild-stage keratoconus, and 54 healthy eyes with minimal pachymetry ≤500 µm, with a mean age of 21.19 ± 2.97, 21.75 ± 1.93, and 21.5 ± 2.95 years, respectively. The area under the receiver operating characteristic curves was used to analyze the diagnostic significance of the Pentacam parameters. RESULTS The anterior and posterior corneal elevations, pachymetric progression, the percentage of thickness increase measurements, overall D value, and topometric indices were statistically significantly higher in subclinical and mild keratoconic corneas than in normal eyes with thin cornea (p < 0.05). All these parameters had sufficient strength (area under the receiver operating characteristic curves >0.90) to differentiate clinical keratoconus. Posterior elevation showed the excellent area under the receiver operating characteristic curves with 100% sensitivity and 100% specificity for this purpose. However, among all parameters studied, the anterior elevation (0.935) showed the excellent area under the receiver operating characteristic curves to differentiate subclinical keratoconus, followed by posterior elevation (0.897), index of height decentration (0.887), and D value (0.882). CONCLUSION The parameters derived from the Scheimpflug device, such as corneal elevations and overall D value, can effectively differentiate subclinical and clinical keratoconus from non-keratoconic thin cornea eyes. However, the specificity levels of these parameters were relatively limited in the diagnosis of subclinical keratoconus.

Abstract
We report a case of a 54-year-old woman presented at the emergency service with complaints of transitory visual obscurations for four days, and headache, nausea and occasional vomiting in the last two months. She had been diagnosed of colorectal cancer one year ago and she was on treatment with oxaliplatin on a FOLFOX schedule. On ophthalmic examination, the vision was of 20/20 in both eyes and bilateral disc swelling was noted. The neurologic examination was normal. Magnetic resonance revealed no changes. A diagnostic lumbar puncture demonstrated an elevated opening pressure of 290 mm H2O with normal compounds. Due to the suspicion of ocular toxicity, oxaliplatin treatment was stopped. Treatment with oral acetazolamide was started and maintained for one month. In three weeks ocular and systemic symptoms totally disappeared and disc swelling gradually improved in the following months. Ocular toxicity has been reported as an infrequent adverse effect of oxaliplatin, but intracranial idiopathic pressure has not yet been described. Findings in this case suggest that oxaliplatin could be the cause for these symptoms. As the use of oxaliplatin is increasing as first-line treatment in colorectal cancer, we have to be alert to its potential toxicity.

Abstract
PURPOSE To study the efficacy and the safety of ultrasound biomicroscopy assisted canaloplasty in the treatment of open-angle glaucoma (OAG) METHODS: A prospective study of uncontrolled open-angle glaucoma patients, or patients with cataracts associated with controlled or uncontrolled OAG under maximal medical therapy who had been subjected to canaloplasty alone or combined with cataract surgery, respectively. Complications, Goldmann intraocular pressure (IOP) and mean number of drugs (ND) were evaluated at 1 day, 1 week, 1 month, and every 3 months. RESULTS Thirty five surgeries were performed (11 canaloplasties, 24 phaco-canaloplasties). The mean IOP (mmHg) dropped from 24.5±5.1, in canaloplasty, and from 19.8±6.4, in phacocanaloplasty, preoperatively, to medium-low levels at all follow-up periods (13.5±1.0 and 11.0±4.2, at 1 year in canaloplasty and phaco-canaloplasty, respectively). The number of grugs used dropped from 3.3±0.5 before surgery to less than of 1 in all follow-up periods (0.5±0.8 at 1 year). The complications were 2 microruptures of the trabeculodescemetic window, 5 entries in the collector channels, 5 choroidal space/anterior chamber passages, 10 hyphemas, 3 hypotonies, one peripheral Descemet detachment, one intracorneal hematoma, two peripheral anterior synechia, one internal iris prolapse, and two suture extrusions to the anterior chamber. CONCLUSIONS Ultrasound biomicroscopy assisted Canaloplasty, alone or combined, provided a sustained IOP reduction to medium-low levels, led to a decrease in the number of drugs and had a good safety profile, making this a good alternative to trabeculectomy.

Abstract
PURPOSE To evaluate the clinical outcomes of topical plus subconjunctival anaesthesia for secondary implantation of foldable intraocular lens (IOL) (Ophtec PC 425Y) in eyes without capsule support through a self-sealing incision. METHODS We reviewed the medical records of 22 patients (22 eyes) who received topical plus subconjunctival anaesthesia for scleral fixation of a foldable IOL through small incision. The scleral incision technique was used for IOL scleral fixation. Twelve eyes had traumatic cataract, seven had postphacoemulsification complications and three were aphakic. We studied visual outcome, intraoperative complications and perioperative pain. Autorefractometry and keratometry measurements and central endothelial cell counts were evaluated 1 day preoperatively and 4 months postoperatively. The level of intraoperative pain was scored on a scale of 1-10, where 1 = no pain and 10 = severe pain. RESULTS Nineteen patients (86%) tolerated the procedure well, giving pain scores of 1-3, and none required supplemental anaesthesia. The mean age of the patients was 60 years. The postoperative best-corrected visual acuity (BCVA) ranged between 20/100 and 20/25. Four months postoperatively, the mean myopic shift by autorefractometry was -1.25 dioptre (D) and the mean postoperative astigmatism was 1.75 D. The mean central corneal endothelial loss at 4 months was 12.24% (range 4.5-17.2%). Five microscopic hyphaema occurred intraoperatively. Four cystoid macular oedema and four peripheral anterior synechia were the only complications, each occurring at the final follow-up. CONCLUSION Topical plus subconjunctival anaesthesia and scleral fixation of foldable IOL (Ophtec PC 425Y) was safe, quick, required a small incision, led to favourable visual outcomes and minimized the risk of intraoperative and postoperative complications in eyes without capsule support. However, a long-term study of a large population is required to confirm these findings.

Abstract
Retinal abnormalities have been described in both animals and humans exposed to cocaine during development. The present study was designed to examine the morphological repercussions of neonatal exposure to cocaine on the developing retina of the rat. Male Wistar rats were given 15 mg/kg body weight per day of cocaine hydrochloride subcutaneously on postnatal days (PND) 0-6, 13 and 29 and sacrificed at PND 7, 14 or 30; controls were given saline. The retinas were processed for electron microscopy. Retinal quadrants were embedded flat and vertical semithin and ultrathin sections obtained. PND 7 sections showed discrete intraretinal hemorrhages, PND 14 sections showed massive intraretinal hemorrhages and images of ischemic necrosis in the nerve fiber layer and PND 30 sections showed cavity lesions in the hemorrhagic areas, gliosis and pigmented macrophage-rich epiretinal membranes; photoreceptor rosettes were also found. These results are the first morphological demonstration of retinal hemorrhages and associated epiretinal membranes following neonatal exposure to cocaine in the rat. These changes are probably related to the ischemia/hypoxia induced by cocaine.

Abstract
The effects of neonatal exposure to cocaine upon the structure of the visual system are poorly understood despite the evidence of eye abnormalities in infants exposed in utero to cocaine. We previously demonstrated alterations in the optic nerve of rats exposed neonatally to cocaine, although no changes were detected in the number of its axons. This study was undertaken to investigate the retinal ganglion cell layer and the size distribution of the optic axons, in an attempt to assess further changes in the visual pathways. Groups of rats (Wistar strain) were given subcutaneous injections of cocaine hydrochloride (15 mg kg-1 body weight day-1) divided into two daily doses, from the day following birth until postnatal day 30 Controls were given subcutaneous saline throughout the same experimental period. Per group, five animals from three different litters were evaluated morphometrically. Following perfusion with aldehydes, samples from the median ventral and dorsal parts of the retina and the optic nerves were processed for electron microscopy. Morphometric techniques at light and electron microscopic levels allowed us to determine the following. (a) In the optic nerve: (1) frequency size-distribution of myelinated nerve fibres; and (2) number of myelin sheaths per fibre. (b) In the retina: (1) thickness of the layers; (2) frequency size-distribution of ganglion layer neurons; (3) mean cell nuclear size; and (4) packing density of ganglion cell layer neurons.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
We determined the effects of cocaine hydrochloride (15 mg/kg body weight/day) or amphetamine sulfate (25 mg/kg body weight/day) on the optic nerve in groups of rats exposed from postnatal day 1 to 30. Qualitative and quantitative studies of cross-sections of the optic nerves showed different patterns of organization, namely the presence of degenerative features in drug-treated animals and significant differences in the proportion of the nerve occupied by glial cells and their processes and nerve fiber bundles. No significant differences of the total number of fibers were found. Taken together, these data indicate that the optic nerve is vulnerable to early exposure to cocaine and amphetamine which cause developmental changes in this link of the visual pathways.
