Objectives: This study aims to analyze the impact of longest treatment-free interval (TFI) between anti-vascular endothelial growth factor (anti-VEGF) injections during the first year of treatment on 5-year best-corrected visual acuity (BCVA) and recurrence of macular edema (ME) in eyes with ME secondary to branch retinal vein occlusion (BRVO).

Methods: A retrospective study including eyes with BRVO, minimum of 5-year follow-up, and available optical coherence topography (OCT) scans. Eyes underwent anti-VEGF loading dose therapy and were treated and monitored with an OCT-guided PRN regimen. Those with a history of ocular comorbidities were excluded.

Results: Total of 60 patient eyes, with 40 females and average age of 71.75 ± 11.07 years. TFI among eyes was 1 month (20%); > 1-2 months (23%); > 2-3 months (18%); > 3-4 months (17%), and >4 months (22%). Forty-three (72%) eyes experienced ME recurrence during the five-year period. Multivariate linear regression shows that TFI (-0.02 [-0.03-0.00], p = 0.021) and baseline BCVA (0.37 [0.08-0.66], p = 0.014) are significant predictors of 5-year BCVA. TFI (Cox Proportional Hazard Ratio 1.34 [1.04-1.72], p = 0.023) and number of injections in the first year (Cox Proportional Hazard Ratio 1.76 [1.01-3.06], p = 0.045) were significant predictors of ME recurrence. Gender, age, type of injection, BCVA, and CMT did not influence recurrence.

Conclusion: For eyes receiving anti-VEGF injections to treat ME secondary to BRVO, TFI is a significant predictor of 5-year BCVA and ME recurrence according to regression models. This study suggests more ME recurrence may be due to increased TFI or indicate more injections needed to treat severe BRVO.

Purpose. To report a rare case of Rosai-Dorfman-Destombes (RDD) disease in a teenage girl exhibiting mild fever, night chills, vertigo, and progressive bilateral vision and hearing loss. Method. Case report of a 15-year-old girl who underwent extensive ophthalmic multimodal imaging and a comprehensive workup evaluation. Results. Multiple choroid lesion masses in both eyes associated with systemic multifocal lymphadenopathy, involvement of the paranasal sinuses, and unusual intracranial manifestations well-shown by magnetic resonance imaging (MRI) and whole-body PET-scan. The PET-Scan and MRI imaging showed dural-based intracranial lesions, choroid-plexus signaling, and meningeal spread, as well as a focus on the paranasal sinuses, which helped determine the best biopsy location for a definitive diagnosis through immunohistochemistry. Conclusions. Here we describe a rare condition of RDD disease with bilateral visual and hearing loss associated with bilateral multiple choroid masses and neurological symptoms in an adolescent female patient. A definitive diagnosis relied on histological assessment, emphasizing the importance of interdisciplinary evaluation. RDD should be considered in the differential diagnosis of choroidal metastasis, tuberculosis, and other lymphoproliferative diseases.

Purpose: We herein report a case of subacute-onset rhino-orbital mucormycosis (ROM) in an acute leukemia patent caused by the rare but most lethal pathogenic fungus - Cunninghamella. To the best of our knowledge, this is the first case of ROM caused by Cunninghamella reported in China.

Case description: A 50-year-old Chinese female with acute leukemia (M2 type) who, following the completion of two cycles of chemotherapy, began to exhibit naso-ocular symptoms. The patient was initially diagnosed with extramedullary leukemia. As the disease progressed, the patient began to develop specific black crust-like necrosis of the right eyelids. Following multidisciplinary treatment (MDT) consultation and tissue biopsy, the patient was finally diagnosed with a rare type of ROM caused by Cunninghamella infection. Although the mortality associated with Cunninghamella infection was significantly greater than that associated with infections caused by other Mucorales, the infection was eventually controlled through the adjustment of the antifungal drug regimen and timely surgical intervention.

Conclusions: ROM infection with Cunninghamella is an extremely rare and fatal fungal infection, and early recognition and diagnosis of the disease is critical to the prognosis. The subacute nature of this case may have been a positive factor in the patient's preservation of life.

Purpose: To describe an alternative technique used in massive post-traumatic cyclodialysis. Classic techniques such as direct cyclopexy are performed ab externo and entail a higher risk of endophthalmitis or ciliary body hemorrhage. Therefore we present a case report using combined sewing machine technique cyclopexy with transscleral diode cyclophotocoagulation for complete post-traumatic cyclodialysis.

Patients: Our patient is a 43-year-old woman who suffered a blunt trauma 9 months ago from an air-bag blunt in a car accident.

Methods: Technique report.

Results: Two weeks post-surgery, there has been an elevation in intraocular pressure (IOP), and the cyclodialysis has been resolved. Additionally, signs of macular hypotony, such as optic nerve head edema and vascular tortuosity, have disappeared. As anticipated, the disappearance of chorioretinal folds occurred later but has also been observed. Furthermore, the best corrected visual acuity has been improved and the induced hyperopia has been corrected from +5 (-1.75 × 20°) to +1.5 (-1.75 × 20°).

Conclusions: Combined sewing machine technique cyclopexy with transscleral diode cyclophotocoagulation for complete post-traumatic cyclodialysis could be an alternative surgical improvement to both direct and indirect cyclopexy. It entails fewer complications, such as endophthalmitis, and offers favorable aesthetic outcomes along with enhanced intraoperative visualization.

Introduction: A concave iris configuration is a characteristic feature of pigment dispersion syndrome (PDS). Therapeutic strategies to modify this configuration may be considered as first-line options for the treatment of ocular hypertension in PDS patients.

Case description: A 37-year-old male patient with myopic anisometropia presented bilateral PDS with concave iris, Krukenberg's spindle and iris transillumination defect in both eyes. The intraocular pressure (IOP) was 27 mmHg in both eyes. Optic nerve and visual field parameters were normal. The right eye was treated with a neodymium:YAG LPI. In the left eye, an implantable collamer lens (ICL) V4c model implantation for myopia correction was performed. Six-months postoperatively, both eyes evidenced an anteriorization of the iris, the morphology of the concave iris improved with the ICL V4c in place, becaming flattener in left eye. The IOP was 18 mmHg without treatment.

Conclusion: This case report reinforces the idea that in myopic patients with a concave iris, the refractive correction approach through ICL V4c implantation might also improve the iris configuration, similarly to laser peripheral iridotomy (LPI). Therefore, in this specific patient profile, this surgical procedure might be considered as a prophylactic treatment alternative to prevent the complications associated with this iris configuration, although its invasive nature should be taken into consideration.

Purpose: This study investigates the natural progression of quiescent macular neovascularization (qMNV) using optical coherence tomography angiography (OCTA).

Methods: The study monitored 30 eyes of 28 qMNV patients over a period of at least six months. Best-corrected visual acuity (BCVA), optical coherence tomography (OCT), and OCTA were used to perform qualitative and quantitative analyses, noting any cases of activation during follow-up.

Results: Among the 30 eyes (14 female, mean age 69.70 ± 7.63 years), 21 had age-related macular degeneration (AMD) and 9 had pachychoroid neovasculopathy (PNV). The mean follow-up duration was 18.9 months. There were no significant changes in qualitative morphological features, BCVA, or choroidal thickness (p > 0.05). However, there was a statistically significant increase in the areas of MNV and flow (p = 0.043 and p = 0.018, respectively). BCVA and MNV area showed no significant correlation (p = 0.103). Four cases (13.33%) showed activation after an average follow-up period of 27.75 months (6 to 48). Additionally, extrafoveal location was identified as a significant risk factor for exudation (p = 0.033).

Conclusion: OCTA is a valuable tool for monitoring qMNV and identifying potential predictors of disease activation. The qMNV area may increase over time, even in the absence of activation. Extrafoveal location appears to be a potential risk factor for qMNV activation.

Purpose: To evaluate photobiomodulation (PBM) safety and efficacy in patient with atrophic AMD and to explore tissue effects using Spectrally Resolved Autofluorescence (SrAF) to identify a potential biomarker indicative of mitochondrial activity, the primary PBM target.

Methods: This retrospective, non-comparative case series involved six eyes of five patients with atrophic AMD, conducted at the Medical Retina and Imaging Unit, IRCCS San Raffaele Hospital in Milan, Italy. At baseline and follow-ups (after one and three months) a complete ophthalmological assessment and multimodal imaging, including spectrally resolved autofluorescence (SrAF), were performed. PBM treatment (Valeda Light Delivery System - LumiThera) was administered in nine sessions over three weeks. The SrAF images were analyzed to evaluate the effect of the treatment.

Results: Six eyes of five patients with atrophic AMD received PBM at baseline. Best corrected visual acuity (BCVA), mean central macular thickness (CMT), mean retinal sensitivity on microperimetry and the atrophic area have remained stable. No eyes developed foveal atrophy after the treatment. The image analysis in SrAF showed an increase in the highlighted area of 4.89% after one month and 17.11% after three months. No adverse systemic or local side effects were reported.

Conclusion: PBM is a safe treatment for the human retina. The evaluation of the retinal area within the green light spectrum (575 nm) in SrAF is a potential indirect biomarker of mitochondrial activity and could be used to assess treatment efficacy in clinical studies.

Introduction: The purpose is to analyze the changes produced in subjects with an overdipper pattern of ambulatory blood pressure monitoring with the aim of understanding the pathophysiology of normal tension glaucoma.

Methods: A cross sectional study was performed in patients exhibiting overdipper and non-overdipper blood pressure patterns, respectively. Different optic parameters were assessed including the analysis of ganglion cell layer (GCL), peripapillary retinal nerve fiber layer (pRNFL) and Bruch's membrane opening-minimum rim width (BMO-MRW), as well as changes produced in choroidal thickness (CT) and lamina cribrosa (LC) position at two different periods of the day (early morning and evening).

Results: A total of 80 eyes (42 overdipper and 38 non-overdipper) were analyzed. A shortening of the distance at the beginning and end of the LC was objectified in the overdipper subjects (p < 0.003) as well as a statistically significant shift of the LC between morning and evening measurements in the overdipper subjects (p < 0.023). In addition, a significant thickening was found in 13 measurements of the horizontal and vertical plane CT (p < 0.029) of the overdipper subjects and a thickening of the CT in both groups in the morning. No significant differences in pRNFL, BMO-MRW and GCL measures were objectified.

Conclusions: Morning assessment in overdipper subjects showed a deeper LC and a LC shift in comparison to evening values. In addition, an increase in CT was found in these subjects. Altogether, these findings could illustrate an etiopathogenic mechanism of the damage produced in normal tension glaucoma associated to the overdipper pattern.

Purpose: This study aims to compare the 3-month clinical outcomes between two enhanced monofocal intraocular lenses (IOLs) following cataract surgery.Setting: Eye Clinic of Careggi University Hospital, Florence, Italy.

Design: Single-center prospective study.

Methods: We included patients with cataract and corneal astigmatism less than 0.75 D, with no ocular comorbidities, who underwent unilateral cataract surgery with implantation of either the Tecnis Eyhance ICB00 (N = 25) or Evolux (N = 25) IOLs. Standard cataract procedures were performed without complications. The main outcome measures included uncorrected and corrected visual acuity at distance (4 m), intermediate (60 cm) and near (40 cm) at 3-month follow-up. Additionally, monocular defocus curves, aberrometric profiles, and perceptions of halo and glare were evaluated.

Results: The study involved 50 patients (26 male, 24 female) with a mean age of 68 ± 8 years. Preoperative characteristics were similar between the groups, and no intraoperative or postoperative complications were reported. Statistically significant differences were observed between the groups, with the Evolux IOL showing superior results (p < 0.05) in terms of uncorrected and corrected visual acuity at near, intermediate, and distance, as well as in aberrometric profiles (lower-order aberration root-mean-square [RMS], higher-order aberration RMS, spherical equivalent RMS, and point spread function) and defocus curves.

Conclusions: Based on our experience, while both IOLs offer substantial visual performance for intermediate and distance vision, the Evolux IOL demonstrated superior mean visual outcomes and objective parameters at the 3-month follow-up compared to the Tecnis Eyhance IOL. This indicates a potential advantage of the Evolux IOL in providing better visual performance.

Purpose: To report a rare case of acute bacterial endophthalmitis that developed after scleral buckling surgery performed with non-contact wide-angle viewing system (WAVS) and chandelier endoillumination.

Case description: A 63-year-old man underwent scleral buckling surgery using a WAVS with chandelier endoillumination for rhegmatogenous retinal detachment repair in his left eye. Seven days after the surgery, the patient noticed a marked decrease in his vision with ocular pain. No anterior chamber inflammation or exudates were found. No focal congestion or exudates were noted at the sclerotomy site. Posterior segment examination revealed severe vitreous haze and yellowish exudates in the vitreous cavity. Ocular ultrasound revealed dense vitritis, complete posterior vitreous separation, a fully attached retina, and a peripheral scleral buckle indent. Vitreous biopsy combined with pars plana vitrectomy with intravitreal antibiotic injections was done immediately, and Staphylococcus epidermidis was detected in the vitreous fluid. Following surgery, the inflammation and infection subsided and the visual acuity recovered to 6/9 in 6 weeks.

Conclusion: Infectious endophthalmitis is a rare occurrence after chandelier-assisted scleral buckling (SB) surgery, characterized by ocular pain and a sudden decline in vision as key symptoms. Clinicians should be cognizant of the possibility of its occurrence following SB surgery, especially when utilizing the WAVS with chandelier endoillumination.
