Remote Topography-Guided Transepithelial Photorefractive Combined Phototherapeutic Keratectomy Telesurgery.

PURPOSE: The purpose of this study was to report the first remote telesurgery in a case of epithelial basement membrane disease with recurrent corneal erosions. METHODS: Topography-guided transepithelial photorefractive combined phototherapeutic keratectomy (PRK-PTK) is a surgical option that treats corneal irregularities and prevents the recurrences of erosions while treating the refractive error. RESULTS: We performed for the first time a remote transepithelial topography-guided combined PRK-PTK using the iRes®2 excimer laser platform (iVIS Technologies, Taranto, Italy), with the surgeon sitting in his own room and controlling the excimer laser in remote with 5G connection through the Remote Control Station and the patient in the operating room. At one-month post-operative, visual acuity was 20/20 and the patient's symptoms subsided. CONCLUSIONS: Our surgery opens the era of telesurgery in the corneal panorama.

Continuous Eplerenone Treatment in Chronic Central Serous Chorioretinopathy: Long-Term Results from a Pilot Study.

Purpose: To assess the long-term morpho-functional retinal and choroidal changes in chronic central serous chorioretinopathy (cCSC) pachychoroid eyes in response to continuous oral eplerenone (EPL) treatment. Methods: This pilot study was conducted on patients with unilateral exudative cCSC. We enrolled a total of 17 exudative cCSC and 17 non-exudative fellow eyes of 17 patients. Baseline best-corrected visual acuity (BCVA) and anatomical (structural optical coherence tomography [OCT] and OCT angiography) parameters in both eyes were collected at baseline. Follow-up data were collected at 6, 12, and 48 months after initiation of EPL treatment. Results: (i) Exudative cCSC eyes: Compared with baseline (0.34±0.13 LogMAR), BCVA significantly improved at follow-up examinations (6 months: 0.28±0.13 LogMAR, p=0.039; 12 months: 0.22±0.11 LogMAR, p=0.025; 48 months: 0.21±0.08 LogMAR, p=0.028). Furthermore, there was a significant reduction from baseline in all structural OCT parameters (subretinal fluid and subfoveal choroidal thickness [SFCT]; p<0.05). (ii) Non-exudative fellow eyes: There was no significant change in BCVA. There was a significant reduction from baseline in SFCT and choriocapillaris flow deficit percentage (p<0.05). Conclusion: In this pilot study, continuous oral EPL therapy in cCSC pachychoroid eyes resulted in long-term morpho-functional improvement. The beneficial effect of EPL occurred within the first year and was maintained after four years. Based on these preliminary observations, EPL may be effective in the exudative forms of CSC.

Correlation between retinal vessel rarefaction and psychometric measures in an older Southern Italian population.

Objective: To explore the linear association between inner retinal layers thickness and macular capillary density compared to variations of global cognition evaluated by psychometric measures in a cohort of Mediterranean subjects aged 65+ years. Materials and methods: We performed a cross-sectional analysis of 574 participants aged 65 years+ drawn from a population-based Southern Italian study. All subjects underwent neurological evaluations, including global cognitive screening, the Mini-Mental State Examination (MMSE) and frontal assessment battery (FAB), together with an ophthalmic examination including optical coherence tomography (OCT) and OCT-Angiography. We assessed the average thickness of the ganglion cell complex (GCC) and the retinal nerve fiber layer (RNFL), the foveal avascular zone area, and vascular density (VD) of superficial (SVD) and deep (DVD) capillary plexi at the foveal and parafoveal area. Linear regression was applied to assess associations of ocular measurements with MMSE and FAB scores. Results: In the linear regression model, foveal DVD (beta = 0.01, 95% CI:0.004-0.052), whole DVD (beta = 0.04, 95% CI:0.02-0.08), and whole SVD (beta = 0.04, 95% CI:0.02-0.07) showed a positive association with MMSE. In addition, foveal SVD (beta = 0.01, 95% CI:0.003-0.05) and whole SVD (beta = 0.03, 95% CI:0.004-0.08) were positively associated with the FAB score. We found no further significant association between the MMSE score or the FAB score and the average thickness of the GCC and RNFL, and FAZ area. Conclusion: A direct linear association between the VD of the macular capillary plexi with global and frontal cognitive functions was observed in elderly subjects.

Loa loa in the Vitreous Cavity of the Eye: A Case Report and State of Art.

Loa loa is a filarial nematode responsible for loiasis, endemic to West-Central Africa south of the Sahara and transmitted by flies. This study reports a case of L. loa in the vitreous cavity of the eye of a young patient, along with an in-depth literature review. A 22-year-old woman from Cameroon who migrated from Cameroon to Italy was referred to the Emergency Ophthalmology Department at Policlinico di Bari in July 2021 with the presence of a moving parasite in the subconjunctiva of the left eye. A recent onset of a papular lesion on the dorsal surface of the right wrist and a nodular lesion in the scapular region were detected. L. loa filariasis was diagnosed based on anamnestic data, clinical and paraclinical signs, and a parasitological test confirming the presence of microfilariae in two blood samples collected in the morning of two different days. Because of the unavailability of diethylcarbamazine (DEC), albendazole (ALB) 200 mg twice daily was administered for 21 days. A mild exacerbation of pruritus occurred during treatment, but resolved with the use of an antihistamine. A single dose of 12 mg ivermectin was prescribed at the end of the treatment with albendazole. Unlike other endemic parasite infections, L. loa is not included in the Global Program to Eliminate Lymphatic Filariasis, because it is not mentioned in the WHO and CDC list of neglected tropical diseases. This can result in an overall risk of lack of attention and studies on loiasis, with lack of data on global burden of the disease.

Live surgery outcomes in cataract surgery.

PURPOSE: To evaluate and compare the outcomes of live surgery (LS) and no-live surgery (NLS) on cataract surgery with implantation of different types of intraocular lenses (IOLs). METHODS: Retrospective, contralateral eye, case series of patients that underwent cataract surgery in live or non-live view during two consecutive editions of national meetings. Both eyes of the same patients were implanted with the same IOL, one in LS and the other in NLS. RESULTS: 108 eyes of 54 patients, aged between 50 and 82 (72 ± 8.2) and implanted with different types of IOLs, were reviewed. Both eyes in each patient were well matched at baseline in terms of intraocular biometric characteristics, corneal curvature and endothelial cell density (ECD) (p > 0.05). There are no statistically significant differences between the biometric and topographic parameters, aberrometric data and the loss of ECD in the post-operative outcomes (p > 0.05). However, comparing the different types of IOLs, there is a significant loss of ECD in eyes implanted with a toric IOL during LS (p = 0.0014 and p = 0.04, in 2017 and 2018 edition respectively). CONCLUSIONS: In this series of live cataract surgery, eyes operated in LS or NLS have comparable outcomes, underlying the importance and the benefits of live view in terms of medical education and the low-risk of complications. Nevertheless, we have found a significant increase in ECD loss in patients implanted with toric IOLs during LS.

Association of Neuroretinal Thinning and Microvascular Changes with Hypertension in an Older Population in Southern Italy.

BACKGROUND: Retinal microvasculature assessment at capillary level may potentially aid the evaluation of early microvascular changes due to hypertension. We aimed to investigate associations between the measures obtained using optical coherence tomography (OCT) and OCT-angiography (OCT-A) and hypertension, in a southern Italian older population. METHODS: We performed a cross-sectional analysis from a population-based study on 731 participants aged 65 years+ subdivided into two groups according to the presence or absence of blood hypertension without hypertensive retinopathy. The average thickness of the ganglion cell complex (GCC) and the retinal nerve fiber layer (RNFL) were measured. The foveal avascular zone area, vascular density (VD) at the macular site and of the optic nerve head (ONH) and radial peripapillary capillary (RPC) plexi were evaluated. Logistic regression was applied to assess the association of ocular measurements with hypertension. RESULTS: GCC thickness was inversely associated with hypertension (odds ratio (OR): 0.98, 95% confidence interval (CI): 0.97-1). A rarefaction of VD of the ONH plexus at the inferior temporal sector (OR: 0.95, 95% CI: 0.91-0.99) and, conversely, a higher VD of the ONH and RPC plexi inside optic disc (OR: 1.07, 95% CI: 1.04-1.10; OR: 1.04, 95% CI: 1.02-1.06, respectively) were significantly associated with hypertension. CONCLUSION: A neuroretinal thinning involving GCC and a change in capillary density at the peripapillary network were related to the hypertension in older patients without hypertensive retinopathy. Assessing peripapillary retinal microvasculature using OCT-A may be a useful non-invasive approach to detect early microvascular changes due to hypertension.

Torkildsen's Ventriculocisternostomy First Applications: The Anthropological Evidence of a Young Slavic Soldier Who Died in the Torre Tresca Concentration Camp (Bari, Italy) in 1946.

Human skeletal remains are considered as real biological archives of each subject's life. Generally, traumas, wounds, surgical interventions, and many human pathologies suffered in life leave identifiable marks on the skeleton, and their correct interpretation is possible only through a meticulous anthropological investigation of skeletal remains. The study here presented concerns the analysis of a young Slavic soldier's skeleton who died, after his imprisonment, in the concentration camp of Torre Tresca (Bari, Italy), during the Second World War (1946). In particular, the skull exhibited signs of surgical activity on the posterior cranial fossa and the parieto-occipital bones. They could be attributed to surgical procedures performed at different times, showing various degrees of bone edge remodeling. Overall, it was possible to correlate the surgical outcomes highlighted on the skull to the Torkildsen's ventriculocisternostomy (VCS), the first clinically successful shunt for cerebrospinal fluid (CSF) diversion in hydrocephalus, which gained widespread use in the 1940s. For this reason, the skeleton we examined represents a rare, precious, and historical testimony of an emerging and revolutionary neurosurgical technique, which differed from other operations for treating hydrocephalus before the Second World War and was internationally recognized as an efficient procedure before the introduction of extracranial shunts.

Comparison of perioperative parameters in one-handed rotational phacoemulsification versus conventional phacoemulsification and femtosecond laser-assisted cataract surgery.

AIM: To compare perioperative parameters of one-handed rotational phacoemulsification technique (one-handed phaco-roll) with each of other two techniques, "Divide et Conquer" and femtosecond laser-assisted cataract surgery (FLACS). METHODS: In this retrospective and comparative cohort study, eyes with uncomplicated cataract (nuclear density grade 2 to 3) treated routinely with one-handed phaco-roll (n=23; Group 1) or "Divide et Conquer" (n=23; Group 2) or FLACS (n=23; Group 3) were enrolled. Intraoperative parameters including effective phaco-time (EPt), ultrasound time (USt), aspiration time, surgical time, phacoemulsification (phaco)-power, balanced salt solution (BSS) use, cumulative dissipated energy (CDE) were recorded and compared. Clinical outcomes including best corrected visual acuity (BCVA), corneal endothelial cell density (ECD), endothelial cell loss (ECL), central corneal thickness (CCT) and central macular thickness (CMT), were assessed and compared pre-operatively and at 1mo after surgery. RESULTS: Aspiration and surgical time, and BSS used were lower in Group 1 (P<0.01) than other groups. EPt, phaco-power and CDE were lower in Group 1 (P<0.05) than Group 2 but not significantly different from Group 3. In Group 1, USt was lower (P<0.05) than Group 2 but higher (P<0.05) than Group 3. BCVA improved in all groups without significant difference between Group 1 and the other ones. No significant differences regarding all post-operative morphologic outcomes (ECD, ECL, CCT, CMT) were reported. No clinical complications occurred. CONCLUSION: One-handed phaco-roll seems to be less time-consuming than "Divide et Conquer" and FLACS and less energy-consuming than "Divide et Conquer". Furthermore, one-handed phaco-roll seems to have an equal safety profile compared to the other two techniques.

Evaluation of Demarcation Line after Epithelium-Off Iontophoresis Corneal Collagen Cross-Linking for Progressive Keratoconus.

The aim of the study was to visualize and evaluate the characteristics and depth of the demarcation line with anterior segment optical coherence tomography (AS-OCT) after epithelium-off iontophoresis corneal collagen cross-linking (epi-off I-CXL). In this prospective, consecutive, single center study 18 eyes of 18 patients with keratoconus were involved. One month after epi-off I-CXL, all the patients underwent an AS-OCT scan to search for a demarcation line and its characteristics. The corneal stromal demarcation line was identified in all the eyes. Mean depth of the corneal stromal demarcation line was 261.8 ± 46.7 µm (range: 184 to 362 µm), at 56.7 ± 12% corneal depth. In conclusion, epi-off I-CXL determines a demarcation line that can be visualized with AS-OCT, which seems clearly distinguishable and similar to that created in standard CXL.

One-Handed Rotational Phacoemulsification Technique.

INTRODUCTION: We described a one-handed rotational phacoemulsification technique to decrease phaco time and power, and surgical stress on the cornea in eyes with different types of cataract. METHODS: In this technique a single sutureless corneal incision was made without any side-port incision. After hydrodissection and hydrodelamination were performed, a phaco tip was positioned in contact with the nucleus beside the capsulorhexis edge. By using a peristaltic pump, phacoemulsification was started with high levels of vacuum to keep the probe tip on the edge of the lens and to ensure the rotation of the nucleus, and with low ultrasound energy. The torsional mode used required less occlusion time and volume of fluid. The inclination of the tip was modified to 45-degree, directing it toward the lens center. So the nucleus was aspirated from the periphery toward the center by a rotational movement. RESULTS: The eye in the technical video had a NC4-NO4 cataract. The preoperative vision in this eye was 20/100 with no improvement with refraction. On postoperative day 1, visual acuity had improved to 20/20. We recorded low intraoperative parameters including ultrasound time (21.4 sec), phacoemulsification power (73%), balanced salt solution used (31 mL) and cumulative dissipated energy (7.27) at the conclusion of the case. After 1 month, Central Corneal Thickness changed from 504 µm to 516 µm, and Endothelial Cell Loss was 1.15%. CONCLUSION: This technique uses a single clear corneal incision, high vacuum and low ultrasound power to reduce the exposition to excessive surgical maneuvers, fluid turbulence and ultrasound energy.

Retinal Vascular Density on Optical Coherence Tomography Angiography and Age-Related Central and Peripheral Hearing Loss in a Southern Italian Older Population.

BACKGROUND: Age-related hearing loss (ARHL) and retinal vessel changes have both been associated to neurodegeneration/dementia, suggesting a possible link between these 2 conditions in older age. We aimed to determine whether superficial and deep vascular density (SVD and DVD) of the capillary plexi of macular vasculature can be associated with peripheral ARHL and age-related central auditory central processing (CAPD). METHOD: We analyzed data on 886 older participants (65 years+, age range: 65-92 years) in the cross-sectional population-based Salus in Apulia Study. Optical coherence tomography angiography was used to measure SVD and DVD of the capillary plexi of the macula at the 3-mm circle area centered on the fovea (whole retina), the parafoveal quadrant, and foveal quadrant. Disabling peripheral ARHL was defined as >40 dB hearing level of pure tone average on the frequencies from 0.5, 1, 2, and 4 KHz in the better ear, and age-related CAPD as <50% at the Synthetic Sentence Identification with Ipsilateral Competitive Message test in at least one ear. RESULTS: DVD at the whole retina and at the parafoveal quadrant were inversely associated only with age-related CAPD (odds ratio [OR]: 0.93, 95% confidence interval [CI]: 0.88-0.96 and OR: 0.94, 95 CI: 0.90-0.99, respectively). No further associations with peripheral ARHL were evident. CONCLUSIONS: Retinal vasculature is associated with central auditory processing pathology, possibly playing an important role in early detection and intervention. The association of retinal vascular density with age-related CAPD may bring us a further step forward in understanding the biological mechanisms underlying the links between neurodegeneration/dementia and ARHL.

Validation of a new system for triage of ophthalmic emergencies: the alphabetical triage score for ophthalmology (ATSO).

PURPOSE: To propose a modified ophthalmic triage system based on simple ophthalmic symptoms, signs and anamnestic data and validate its safety and effectiveness. METHODS: Phase 1 of the study was a retrospective review of chart records of patients admitted at the ophthalmic emergencies room (OER); phase 2 was a prospective study conducted on all consecutive patients presenting in the OER between April 1st, 2018, and May 30th, 2018. We selected the following six factors as predictors of urgency levels: altered vision, ocular behavior, color, distress, eye trauma, floaters and flashes. ATSO final score can be eventually converted into risk groups: low-risk group (scoring 0-3), intermediate-risk group (scoring 4-5) and high-risk group (scoring > 6). RESULTS: A total of 953 consecutive patients who presented to our OER over a two-month period were considered for participation in the study. The male-to-female ratio was 1.24:1. The mean age of the participants was 53 years (range 18-92, SD 19 years). ATSO score significantly correlated with urgency levels (p < .00001). The sensitivity of ATSO in differentiating urgent from non-urgent conditions was 91.4%, and the specificity was 98.2%. All hospitalized patients (30, 3.15%) have been coded as intermediate/high risk according to the ATSO score. CONCLUSION: The use of the ATSO score for patients at the OER provides the clinician with a reliable predictor of urgency, being at the same time safe and effective. The ATSO score may represent a valuable tool to implement triage of ocular patients in the emergency department.
