Purpose: Radiation-induced scleral necrosis (RISN) is a less frequent complication of brachytherapy for uveal melanoma, and may require surgical treatment in selected cases. We aimed to identify the prognostic factors for RISN treatment.

Methods: All patients with brachytherapy for uveal melanoma treated at our institution between 01/1999 and 12/2016 who developed RISN were followed until 02/2021. Various parameters were evaluated through univariable and multivariable Cox regression analysis. The surgical intervention due to RISN was the principal outcome event of this study.

Results: Of 115 patients in the final cohort, 51 individuals (44%) underwent RISN treatment (conjunctival revision [n = 2], patching [n = 46] or enucleation [n = 3]) at median 1.80 months after RISN occurrence. Significant RISN characteristics were summarized into a novel RISN severity scale - Grade I: largest diameter ≤ 5 mm and no progression; Grade II: largest diameter > 5 mm or any progression during the follow-up; Grade III: presence of uveal prolapse; and Grade IV: leakage through open eyewall perforation. In the multivariable analysis, the RISN severity scale (aHR = 2.37 per grade increase, p = 0.01) and the time between brachytherapy and RISN occurrence (<15 months, aHR = 6.33, p < 0.0001) were independently associated with the study endpoint. The RISN severity scale showed high diagnostic accuracy for prediction of RISN treatment (AUC = 0.869).

Conclusions: In our series, about the half of RISN cases underwent surgical treatment. The presented novel severity scale for RISN might become a helpful tool for clinical management of individuals with RISN. We recommend external validation of the diagnostic accuracy of the presented scale.

Purpose: To investigate safety and efficacy of the XEN gel stent in patients with pigmentary glaucoma (PG).

Methods: A retrospective analysis of 26 eyes of 19 patients with PG undergoing XEN gel stent implantation was performed. Best-corrected visual acuity, intraocular pressure (IOP), and number of antiglaucoma medications were analyzed preoperatively, and at 2 weeks and 3, 6, 12, and 24 months after surgery. Success, needling, and complications were analyzed. Complete success was defined as an IOP reduction of >20% and achieving a target IOP of ≤18, ≤15, or ≤12 mmHg without antiglaucoma medication. Qualified success was indicated if the IOP target was reached with or without medication.

Results: Mean IOP decreased significantly from 27.6 ± 14.3 (standard deviation, SD) mmHg to 14.3 ± 4.6 mmHg after one year (p < 0.001) and 15.1 ± 2.7 mmHg (p < 0.001) after two years. The median number of hypotensive drugs declined significantly from 4 (range: 3-5) to 0 (0-2) and 0 (0-3) after one and two years, respectively. After two years, complete success with an IOP of ≤18 mmHg and ≤15 mmHg was achieved in 73.1% and 61.5%, respectively. Half of the eyes required needling after a median time of 8 months (0.5-34 months). No sight-threatening complications were observed.

Conclusion: The XEN gel stent is a safe and effective surgical treatment option for PG. Needling is an important part of the procedure and should be communicated preoperatively to the patients.

Introduction: We report a case of early-onset lipemia retinalis secondary to the FLAG-Ida protocol in the treatment of acute myeloid leukemia (AML) in an 11-year-old girl.

Case report: An 11-year-old patient, diagnosed with AML at four months old, experienced a relapse and was treated with the FLAG-Ida protocol (fludarabine, idarubicin, granulocyte-colony stimulating factor, and high-dose cytarabine). Prior to allogeneic stem cell transplantation, she underwent a pre-transplantation eye examination. The patient exhibited normal visual acuity in both eyes. Fundus examination revealed cream-white retinal vessels and a salmon-pink retina, indicative of grade 3 lipemia retinalis. Laboratory tests, normal before treatment initiation, showed significantly elevated serum cholesterol (727.6 mg/dL) and triglyceride (6015.6 mg/dL) levels post-treatment. After receiving fenofibrate, these levels decreased markedly, and the retinal vessels normalized on follow-up fundus examination.

Conclusion: Lipemia retinalis, characterized by creamy-white retinal vessels resulting from hypertriglyceridemia, can develop as a secondary condition to chemotherapy. Early detection and treatment of hyperlipidemia are crucial to prevent severe ocular and systemic complications. This case highlights the importance of monitoring lipid levels and conducting thorough ophthalmologic examinations in patients undergoing chemotherapy.

Purpose: To report cilioretinal artery occlusion in a patient undergoing cataract and macular hole surgery.

Material and method: A 78-year-old male patient was operated on for a left eye cataract and tractional macular hole. The patient had no intraoperative problems and developed sudden visual loss on the 15th postoperative day. Optic coherence tomography (OCT), fundus fluorescein angiography (FFA), and optic coherence tomography angiography (OCTA) images revealed occlusion of the cilioretinal artery. After medical treatment and 20 sessions of hyperbaric oxygen therapy, the best visual acuity was 50 cmFC, the optic nerve was pale, the macula was ischemic, and the central macular thickness was 139 microns at the last eye examination.

Discussion: Mitigating the risk of cilioretinal artery occlusion after vitreoretinal surgery requires a comprehensive approach that addresses patient-specific factors, surgical techniques, and perioperative management.

Conclusion: Occlusion of the cilioretinal artery may rarely occur after cataract and macular hole surgery. Careful follow-up, early diagnosis, and prompt intervention can minimize visual loss.

Geographic atrophy (GA), a late manifestation of age-related macular degeneration (AMD), leads to irreversible vision loss. Early identification of precursor lesions, such as incomplete and complete retinal pigment epithelium and outer retinal atrophy (iRORA and cRORA), is crucial for predicting GA formation. The latter stage has been associated with irreversible and progressive changes, and the eventual development of a dense scotoma on the compromised area. We present an 80-year-old woman with AMD in both eyes, demonstrating progressive changes over a 2-year follow-up. While the right eye developed cRORA with vision decline, the left eye exhibited unexpected restoration of the outer retinal layers within the cRORA lesion. This finding challenges the notion of "end-stage atrophy" in GA development and highlights the potential reversibility of early atrophic lesions. Recognizing these dynamics has implications for the development of targeted therapies aimed at preserving vision in AMD's early stages.

Purpose: To report a case of punctate inner choroiditis (PIC) and subsequent choroidal neovascular membrane (CNVM) development in a young, high myope following vitreoretinal surgery for rhegmatogenous retinal detachment.

Case description: A 44-year-old male with high myopia underwent pars plana vitrectomy for subtotal retinal detachment in the left eye, followed by cataract extraction and silicone oil removal. Three years postoperatively, he presented with blurred vision, and fundus examination revealed PIC lesions at the posterior pole. Spectral-domain optical coherence tomography (SD-OCT) showed characteristic features of PIC, including hyperreflective nodule-like elevations, disrupted ellipsoid and interdigitation zones, retinal pigment epithelium (RPE) elevations and increased choroidal hyper transmission signals.

Results: Initially, no treatment was initiated, and the patient was monitored. Three years later, the patient experienced further vision loss, and fundus examination showed progression of PIC lesions and new CNVM formation in the left eye. The patient was treated with systemic corticosteroids and an intravitreal anti-VEGF injection (Razumab^® 0.5 mg/0.05 ml). Three weeks after the intervention, SD-OCT showed regression of the CNVM, and the patient's visual symptoms improved.

Conclusion: This case underscores the importance of long-term follow-up and timely intervention in managing PIC, especially in high myopes post-retinal surgery. Early identification and treatment with systemic corticosteroids and anti-VEGF therapy are crucial to preserving visual function and preventing severe complications like CNVM.

Purpose: To assess the effect of Glaucoma awareness, knowledge, and anxiety on patients under visual field analysis by Humphrey's visual field analyzer (HFA) and optical coherence tomography(OCT).

Methods: This prospective comparative cohort study included glaucoma patients undergoing HFA (Group A)(n = 150) and OCT(Group B) (n = 150). Each group consisted of 75 newly diagnosed patients and 75 patients who were on follow-up. Participants completed State trait anxiety inventory form Y2(STAI) before and after the test to assess pre-test and intra-test anxiety. Another validated and structured questionnaire was used to assess patient awareness and knowledge of glaucoma. Anxiety scores were used to make correlations and comparisons between the two groups and also against visual field reliability indices. The impact of awareness on anxiety scores and its correlation with reliability indices were also determined.

Results: Overall pretest and intratest anxiety scores in patients undergoing HFA were 52.39(9.5) and 52.45(8.6)and OCT 53.04(8.0) and 53.83(8.2) respectively.Pretest anxiety was less in follow-up patients of both groups(Group A-51.04,Group B-52.72).There was no statistically significant difference between the groups(pretest p = 0.52,Intratest p = 0.15). Anxiety score was found to be significantly high in female participants(54.07,p = 0.01)and those without awareness(p < 0.001). Patients with education of graduation and above in group B had significantly lower anxiety scores(p = 0.007).

Conclusion: Anxiety levels induced by both diagnostic modalities HFA and OCT appear to be similar and it does not affect the reliability indices.Anxiety score was higher in female participants and participants lacking disease awareness.

Purpose: To present a rare case of PASCAL photocoagulation-induced choroidal effusion and serous retinal detachment in a patient with diabetic retinopathy.

Methods: A case report.

Case description: A 68-year-old man with type 2 diabetes mellitus presented with decreased vision in both eyes. His best corrected visual acuity (BCVA) was 0.39 logMAR units in both eyes. The patient underwent panretinal photocoagulation (PRP) in two quadrants of both eyes on the same day according to his fundus fluorescein angiography. Three days after the first session of PRP, the BCVA in his left eye deteriorated by 2.0 logMAR units. Fundoscopic examination detected a significant choroidal effusion in inferonasal quadrant of the left eye. A macular Spectral-Domain Optical Coherence Tomography (SD-OCT) scan showed a large macular serous retinal detachment in the left eye. Topical steroid, topical cycloplegic, and 64 mg oral methylprednisolone were initiated. Two weeks later, his BCVA returned to the level of the first visit with a completely resolved choroidal effusion and no subretinal fluid.

Conclusion: Considering the inflammatory and destructive mechanism of PRP, the laser operator should use the minimum power necessary to avoid possible chorioretinal complications.

This review article explores the relationship between hyperglycemia during pregnancy and the visual development of offspring, specifically focusing on refractive error. The authors conducted a comprehensive search for relevant articles in various databases and assessed the methodological quality of the included studies. The findings consistently indicate that hyperglycemia during pregnancy can have a detrimental impact on the structural and functional aspects of visual development in offspring. The intrauterine hyperglycemic environment appears to negatively affect the retina and lens, leading to refractive errors. In conclusion, there is likely an association between hyperglycemia during pregnancy and the development of refractive errors in offspring.

Purpose: Geographic atrophy (GA) is a severe complication of age-related macular degeneration (AMD) and leads to irreversible visual decline. To date, no effective treatment is available for GA patients. However, a number of new therapies have recently been approved and several others are in the pipeline. This rapid evolution of prospects for GA patients requires constant updating of ophthalmologists' understanding of GA and its management so as to provide the appropriate treatment. For this reason, Società Italiana di Scienze Oftalmologiche (S.I.S.O.) has designed a specific survey to gauge the position of Italian ophthalmologists in this regard.

Methods: The three hundred and sixty-five Italian ophthalmologists who agreed to take part received a seventeen-part questionnaire guaranteeing privacy and anonymity. The survey was compiled through an online portal and the results were sent directly to S.I.S.O. ETS. Two graders analyzed the data and recorded the results.

Results: The results showed a high level of self-assessed awareness and understanding of GA, as well as considerable willingness to further improve knowledge of the disease. Most of the participants claimed to have effective rules of conduct in place for managing GA patients, including prompt response, involving a high prevalence of nutraceutical prescriptions and lifestyle recommendations.

Conclusions: This survey provided an overview of how GA patients are managed in Italy. The Italian ophthalmology community appears to be ready to adopt the upcoming treatments for GA.
