The Riddle of the Double Vision-A Rare Case of Intracranial Tumor: When Imaging Resolves the Mystery.

A 77-year-old-man with arterial hypertension, diabetes mellitus type II presented at our clinic for a routine ophthalmological exam. He complained of intermittent double vision. The ophthalmic examination revealed paralysis of III (n. oculomotorius) and VI (n. abducens) cranial nerves with ptosis, deficit in elevation and abduction of the left eye. The patient underwent urgent MRI imaging of the brain/orbits and paranasal sinuses, and urgent neurological assessment. MRI revealed a volume-occupying process, starting from the posterior wall of the left maxillary sinus with perineural diffusion and involvement of the homolateral trigeminal nerve, intracranial spread in the medial cranial fossa and involvement of the cavernous, sphenoidal sinuses and the orbital apex on the left side. Biopsy was performed, and the histology resulted in sinonasal squamous cell carcinoma with intracranial spread.

Low Rate of Postoperative Pterygium Recurrence in Patients under Treatment with Low-Dose Oral Doxycycline for Chronic Blepharitis: A First Report.

PURPOSE: Low doses of systemic doxycycline (LD-SD) inhibit angiogenesis and the expression of matrix metalloproteases, which are determinants of pterygium progression. This study aimed to compare the recurrence rate and visual outcome of pterygium excision in patients undergoing chronic treatment with LD-SD for chronic refractory blepharitis and LD-SD-naive patients. METHODS: A retrospective analysis of patients that underwent surgical excision and conjunctival graft apposition was conducted. Patients were divided in a TETRA group (under LD-SD treatment at the moment of surgery) and a control group. The main outcome was the rate of recurrence at 1 year postoperatively. Secondary outcomes were the comparisons of surface regularity, visual quality, and dry-eye symptoms at 6-week, 6-month, and 1-year follow-up in the two groups. RESULTS: The TETRA group showed a significantly lower rate of 1-year recurrence both in primary (p = 0.034) and recurrent (p < 0.001) pterygia. The best corrected visual acuity (BCVA), astigmatic error, corneal total root mean square (RMS), and ocular surface disease index (OSDI) significantly reduced during the follow-up in both groups. The surface asymmetry index and high-order aberrations (HOAs) significantly reduced only in the TETRA group. The final BCVA was significantly higher, while the OSDI score and total RMS and HOAs were significantly lower in the TETRA group compared to the control. CONCLUSIONS: Patients under treatment with LD-SD showed a lower rate of recurrence at 1-year follow-up compared to controls. These patients also experienced higher BCVA and surface regularity and less dry-eye symptoms.

Persistent Conjunctival Chemosis after Lower Lid Blepharoplasty: A Comparison of Different Surgical Techniques.

Background: Conjunctival chemosis, a complication of lower blepharoplasty, can cause persistent discomfort and functional disturbances with worsening in the postoperative period following surgery. Methods: A review of the records of the lower blepharoplasty procedures carried out at the Humanitas Research Hospital, Rozzano, Milan, Italy was performed. Patients were categorized into two groups depending on the procedure performed: (1) transconjunctival blepharoplasty with the removal of the fatty lodges with canthopexy and (2) transcutaneous blepharoplasty with the removal of the fatty lodges with lateral canthoplasty. Each group was further divided into two more groups based on the surgical method used, that is either (a) cold blade and disposable cautery or (b) radiofrequency cut and coagulation and colorado tip (respectively 1a, 1b, 2a and 2b). All patients underwent a postoperative follow-up up to 24 months, which included an evaluation of cosmetic appearance, eyelid scarring and the severity of chemosis. The aim of the study was to investigate which of the surgical procedures causes a lower incidence of persistent type 3 conjunctival chemosis. Results: A total of 1047 patients who underwent lower lid blepharoplasty were included in the study. A total of 512 patients underwent transcutaneous blepharoplasty and 535 underwent the transconjunctival procedure. Among the first group of patients, 266 belong to group 1a and 246 to group 1b. In the second group, 264 were categorized as group 2a and 271 as group 2b. The incidence of type 3 chemosis in the transcutaneous blepharoplasty procedure with lateral canthoplasty was statistically significantly higher than in the transconjunctival approach, considering both the cold blade and the radiofrequency (p = 0.012, 0.010, 0.006, 0.004, respectively). Conclusions: A higher incidence of persistent type 3 conjunctival chemosis is associated with lateral canthus surgery and with the use of radiofrequency.

Outcomes in the Treatment of Subretinal Macular Hemorrhage Secondary to Age-Related Macular Degeneration: A Systematic Review.

Background: Subretinal macular hemorrhage (SRMH) secondary to age-related macular degeneration (AMD) is a relatively rare condition in ophthalmology characterized by blood collection between the neurosensory retina and the retinal pigment epithelium (RPE). Without prompt treatment, visual prognosis is poor. A plethora of treatment approaches have been tried over the past years ranging from intravitreal anti-vascular endothelial growth factor (anti-VEGF) monotherapy to direct subretinal surgery, with no conclusive superiority of one over the other. Materials and Methods: We conducted a systematic review of the outcomes and treatment modalities of SRMH from inception to 14 June 2022, following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines (PRISMA). The level of evidence was assessed for all included articles according to the quality of evidence according to the Grading of Recommendations Assessment, Development and Evaluation (GRADE) system. Results: A total of 2745 articles were initially extracted, out of which 1654 articles were obtained after duplicates were removed and their abstracts screened. A total of 155 articles were included for full-text review. Finally, 81 articles remained that fulfilled the inclusion criteria. Conclusions: Even though there are solid results supporting a variety of treatments for SRMH, the best treatment modality has still not been conclusively demonstrated and further research is needed.

Ten-Year Follow-Up of Orbital Volume Augmentation With Calcium Hydroxyapatite Filler in Postenucleation Socket Syndrome.

PURPOSE: To describe the efficacy and persistence of injectable calcium hydroxyapatite (CAHY) to correct orbital volume deficit in postenucleation socket syndrome. METHODS: An observational study was conducted as a clinical review of all patients in the authors' practice who received injectable CAHY placed in the extraconal and intraconal space to increase orbital volume with a 10-year follow up. The amount of CAHY to be injected was defined according to the degree of orbital volume deficit. Patients previously treated with radiotherapy or with a conjunctival fornix insufficient to accommodate the external prosthesis were excluded. All the patients with at least 10 years of follow up were included in the study. RESULTS: Thirty-one postenucleation socket syndrome patients received injectable CAHY for orbital volume augmentation, with a 10-year follow up. The mean amount of preoperative relative enophthalmos measured by Hertel's exophthalmometry was 14.16 ± 2.15. An increase in the mean orbital volume of 3.35 ± 0.91 at 6 months and 2.97 ± 1.35 at 10 years was obtained. The mean follow-up was 219 ± 18 months (range, 184-240). Patients demonstrated clinical and cosmetic improvement that was observed to continue for 10 years. The complications were peribulbar ecchymosis, 2 extrusions of the internal prosthesis, and 2 ptosis. CONCLUSIONS: Injectable CAHY provides safe, simple, repeatable, and cost-effective technique to treat volume deficiency in the enophthalmic orbit in the long term. The volume augmentation obtained with this semipermanent filler demonstrated a lasting effect in the orbit with negligible loss of volume at 10 years.

Early versus Late Pars Plana Vitrectomy in Vitreous Hemorrhage: A Systematic Review.

Background: Vitreous hemorrhage (VH) is a common vitreoretinal condition causing impairment of vision due to various etiologies. No consensus exists on the best timing for performing pars plana vitrectomy (PPV) in fundus-obscuring VH. Materials and Methods: Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) standards, we conducted a systematic review of the timing of PPV in VH. We assessed the strength of the evidence using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach for all the included publications, in accordance with the 2011 Oxford Centre for Evidence-Based Medicine (OCEBM) recommendations. Results: A total of 1731 articles were identified. Following the removal of duplicates and screening of abstracts, 1203 articles remained. Subsequently, a comprehensive full-text review of 30 articles was conducted. Ultimately, 18 articles met the predefined inclusion criteria. Conclusions: Despite the small number of studies on the timing of treatment for VH, the advantage of early over late PPV seems to be a reasonable approach in selected cases, and it might be considered modern standard care.

Recurrence of Basal Cell Carcinoma Treated with Surgical Excision and Histopathological Analysis with Frozen Section Technique with Complete Margin Control (CMC-FS): A 15-Year Experience of a Reference Center.

BACKGROUND: Basal cell carcinoma (BCC) is the most common type of eyelid malignancy and it is considered to be dangerous due to its proximity to functionally essential organs. Early diagnosis and complete excision of the primary lesion are crucial to prevent infiltration and metastasis. The study aims to evaluate the extent of recurrence in subjects affected by BCC of the upper third of the face treated with surgical eradication and the frozen section technique with complete margin control (CMC-FS), in comparison with the gold standard Mohs micrographic surgery (MMS). MATERIALS AND METHODS: The study included 111 patients with 111 biopsy-proven eyelid BCCs. On clinical examination, all lesions were removed with 2 mm margins clinically free of neoplasm. Prior to reconstruction, CMC-FS analysis of all surgical margins was performed on each tumor for histopathologic confirmation. Subsequently, all margins were presented for the permanent paraffin sections. RESULTS: There were 69 primary carcinomas and 42 secondary carcinomas among the 111 samples. No recurrence occurred in 109 tumors followed-up for at least 5 years, with a total recurrence rate of 1.8%. The median time between lesion excision and diagnosis of recurrence was 20 months. CONCLUSIONS: at 5-year follow-up, CMC-FS guided excision of BCCs of the eyelids resulted in recurrence rates equivalent to MMS. Intraoperative microscopic control of all margins reduced the recurrence rate of the upper third of the facial BCCs, correlating with easier reconstruction with better esthetic and functional outcome.

Surgical Tips for Aesthetic Lower Lid Blepharoplasty: Prevention of Round Eye.

In the present study, we highlight surgical tips based on our experience in lower eyelid blepharoplasty. These have been shown to be crucial in the prevention of several complications, specifically lateral lower-lid displacement. Methods: A series of bilateral lower-lid blepharoplasties were performed on 280 patients at Humanitas-Research-Hospital (Milan, Italy) between January 2016 and January 2020. Patients with a history of lower-lid blepharoplasty and patients requiring canthopexy/canthoplasty were excluded. Needing to singularly evaluate and correct several lower-eyelid structures to obtain a harmonic result, we preoperatively assessed the amount of skin excess, the eyelid margin malposition relative to the globe, and the presence/absence of herniated fat-pads. Pre- and postoperative standard photographs were collected. Patients were evaluated by measuring scleral show, snap-back test, and distraction test. Blinded-fashioned photograph analysis was performed by independent plastic and oculoplastic surgeons who did not execute the procedures. A visual analogue scale was administered to all patients to assess satisfaction. Results: In total, 280 patients underwent successful lower blepharoplasty, with satisfactory results of scleral show, snap-back test, and distraction test. Of the 280 patients, four presented postoperative complications. At 10-month follow-up visit, we achieved a mean patient visual analogue scale satisfaction score of 8.4. Postoperative surgeon's photographs mean score was 4.5. Conclusions: Without the use of muscle flaps, our technique averts tarsal ligament misposition, preserves orbicularis-muscle innervation, and limits thermal spread, assuring excellent stability of results and high patient and surgeon satisfaction. Cosmetic outcome in terms of symmetry, appearance, and lower lid line definition revealed high satisfaction with the result over time, with a remarkably low complication rate.

Antiplatelets and Anticoagulants in Vitreoretinal Surgery: A Systematic Review.

Background: Antiplatelets and anticoagulants have substantially influenced contemporary vitreoretinal surgical practices. The availability of new oral blood thinners has recently spurred a renewed interest in the clinical approach to vitreoretinal surgical conditions since it may be difficult for the surgeon to collect sufficient evidence-based data to decide whether to discontinue or continue such medications. Materials and Methods: We conducted a systematic review on the use of antiplatelets and/or anticoagulants in the perioperative setting in vitreoretinal surgery and their possible complications, following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The level of evidence, according to the Oxford Centre for Evidence-Based Medicine (OCEM) 2011 guidelines, and the quality of evidence, according to the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system, were assessed for all included articles. Results: In total, 2310 articles were initially extracted, out of which 1839 articles were obtained after duplicates were removed and their abstracts were screened. A total of 27 articles were included in the full-text review. Finally, a remaining 22 articles fulfilled the inclusion criteria. Conclusions: Even though there is just a small number of studies with solid results, the advantage of using antiplatelets and/or anticoagulants in vitreoretinal surgery seems to outweigh the disadvantages, which are mainly related to postoperative hemorrhagic complications.

Effects of prostaglandin analogues on epiphora persistence after EN-DCR: A hypothesis-generating study.

Purpose: To explore the relationship between topical antiglaucoma therapy, both prostaglandin and non-prostaglandin based eyedrops, and persistence of epiphora in glaucoma patients who underwent EN-DCR surgery for PANDO. Methods: prospective observational cohort study of all over 65 years-old patients with a dacryo-CT documented diagnosis of PANDO who underwent EN-DCR, were affected by glaucoma and treated with either topical monotherapy prostaglandin eyedrops or other antiglaucoma molecules, up to 12-month postoperative follow-up. Patients were assessed with Fluorescein Dye Disappearance Test and Munk scale. Results: Fifteen right eyes from 15 PG-group patients and 15 eyes right eyes from 15 non-PG-group patients were considered. Epiphora occurred in 1/15 (7%) of PG-group patients at 3 months, in 8/15 (53%) at 6 months, and in 11/15 (73%) at one year. In comparison, only 1/15 of non-PG-group patients developed epiphora at 6 months. The relative risk of epiphora in PG-group patients versus non-PG-group patients was 3.00 (95% CI, 0.13-68.1; p = 0.99) at 3 months, 8.00 (95% CI, 1.14-56.3; p = 0.014) at 6 months, and 11.0 (95% CI, 1.62-74.9; p < 0.001) at 12 months. Conclusion: Based on our results, we speculate that prostaglandin eye drops may affect the outcome of EN-DCR in terms of increasing epiphora recurrence from early to late postoperative follow up. The toxicity of antiglaucoma eye drops might damage spiral fibers of the mucous membrane of the lacrimal system inducing fibrosis by a proinflammatory mechanism.

Clinical outcome and quality of life of lacrimal sac mucocele treated via endoscopic posterior approach.

OBJECTIVE: Dacryocystorhinostomy (DCR) is the surgical treatment for lacrimal sac mucoceles (LSM), yet variants of the procedure are several. Since LSM causes bone remodeling and thinning, especially of the lacrimal bone, osteotomy at that site is reasonably the easiest. The aim of the study is to support treatment of LSM via a posterior DCR approach, in a large cohort of cases, and report patients' quality of life after the procedure with validated questionnaires. METHODS: Single-center observational retrospective study on a specific methodology (endoscopic-DCR via posterior approach). Consecutive patients with LSM were enrolled in 2008-2020; CT scans were reviewed, bone thickness was measured bilaterally and compared. Resolution of mucocele, epiphora and infection were analyzed after 6-months. Patients were administered the Munk Score and Lacrimal Symptom Questionnaire (Lac-Q). Statistical analysis was done to compare bone thickness between the two sides; descriptive analysis of the questionnaires results was presented. RESULTS: Forty-four patients with LSM were enrolled. The LSM side showed frontal process thickness of 4.00 ± 1.06 mm (vs 3.90 ± 1.03 on the unaffected side; p = 0.23) and a lacrimal bone of 0.32 ± 0.12 mm (vs 0.41 ± 0.12; p < 0.001). Resolution of infection was achieved in 97.4% cases, anatomical patency in 87.2%. After 5 years, 84.6% of patients reported no relevant epiphora (Munk score 0-1). Social impact (Lac-Q) due to lacrimal malfunctioning was still noted in 30.8% patients. CONCLUSIONS: Adult LSM is a rare condition and DCR remains the mainstay of treatment. LSM physiopathology may support a preferred surgical choice via a posterior approach. Despite objective patency, some lacrimal way malfunctioning may be experienced in a minority of cases.

Inferolateral Transorbital Endoscopic Approach for Spheno-Orbital Meningiomas.

ABSTRACT: Spheno-orbital meningiomas (SOM) are slow growing tumors that often cause proptosis and visual deficits, due to direct compression of adjacent structures or hyperostosis of surrounding bones.Traditionally, these lesions are approached via a lateral transcranial route. Recent interest in mini-invasive surgery and endoscopy brought many authors to study different trans-nasal or transorbital approaches.The authors report a surgical case series with 3 patients with proptosis due to SOM who underwent surgery in our institution via an inferolateral trans-orbital endoscopic approach. The authors described our surgical technique and the authorsretrospectively reviewed the clinical and radiological outcomes of the patients.All 3 patients had an effective orbital decompression with improvement of the proptosis and pain relief. Histological examination was possible and no intraoperative nor postoperative complications were observed.Therefore, the authors consider inferolateral trans-orbital endoscopic approach as a feasible approach for lesions involving the lateral orbit compartment arising from middle cranial fossa or from orbit itself.

Applying the Exoscope to Lacrimal Surgery: Preliminary Experience.

PURPOSE: The aim of the study was to investigate the role of the exoscope as an assisting tool in endoscopic dacryocystorhinostomy (e-DCR). MATERIALS AND METHODS: In this observational retrospective study, the application of the VITOM® exoscope was studied in a group of 21 patients undergoing mono- or bilateral DCR. The primary endpoint was to evaluate resolution of symptoms (epiphora/dacryocystitis) at the 6-month follow-up and time for surgery. Qualitative features of the exoscope (intraoperative view of the surgical field) and comparison with the typical setting for DCR were analyzed as secondary endpoints. A questionnaire was administered to surgical team members (ENT surgeon, ophthalmologist, and scrub nurse) to evaluate the perceived quality of this new technology (12 items valued as "good" = 2, "acceptable" = 1, and "not acceptable" = 0). A questionnaire score of 24 out of 24 was valued as "completely approved," score 20-23 as "moderately approved," and score ≤19 as "weakly approved." Patients were divided into 3 consecutive groups, and questionnaire scores by each team member were analyzed for tendencies. Statistical analysis was performed to test significance at p < 0.05. Local Ethical Committee approval was obtained. RESULTS: No significant differences were found between exoscope-set DCR and classic setting for concerned patient outcomes (failure rate: 3.2 vs. 3.8%, respectively, p = 0.896) and mean time for surgery (20' vs. 23', respectively, p = 0.091). The exoscope was valued by surgical team members as "completely approved" in 55.5% of cases, "moderately approved" in 39.7%, and "weakly approved" in 4.8%. Questionnaire scores by the ENT, ophthalmologist, and scrub nurse showed an average increase in the 3 consecutive groups (p = 0.119, p = 0.024, and p < 0.001, respectively). CONCLUSIONS: The exoscope is a new tool that may support e-DCR. It has no effects on symptom outcomes (epiphora/dacryocystitis) and time for surgery compared to classic DCR. Based on self-perception, this new technology was accepted by all team members.

Epiphora and unrecognized paranasal sinuses pathology.

PURPOSE: to report five patients all presenting with persistent unilateral epiphora as a sign of unexpected and rare lesions causing Secondary Acquired Nasolacrimal Duct Obstruction (SANDO) and the risks associated to an incomplete diagnostic work-up. OBSERVATIONS: the cases presented are: (1) Fungus ball, (2) Pyogenic granuloma, (3) Sinonasal inverted papilloma (4) Sinonasal inverted papilloma with synchronous squamous cell carcinoma, (5) Squamous cell carcinoma of the lacrimal sac. CONCLUSIONS AND IMPORTANCE: masses are uncommon but not a rare cause of nasolacrimal duct obstruction. Surgical teams performing large numbers of dacryocystorhinostomies should be aware of such pathology and perform a systematic multidisciplinary approach.

Small lymphocytic lymphoma in true trilineage hematopoietic tissue within heterotopic ossification in an enucleated blind painful eye: a case report.

BACKGROUND: The finding of hematological malignancies within bone marrow in heterotopic ossification has been reported only a handful of times previously in the literature. We described a case of true trilineage hematopoiesis in an excised area of heterotopic ossification from an enucleated blind painful eye. CASE PRESENTATION: A 70-year-old Caucasian man, positive for asymptomatic lymphoplasmacytic lymphoma, presented with a blind painful right eye in our ophthalmology department to evaluate enucleation bulbi. After enucleation, a histopathologic examination revealed the presence of intertrabecular infiltration in the metaplastic bone marrow of non-Hodgkin B lymphoma, with small lymphocytes, with similar characteristics to the already known disease. CONCLUSION: This uncommon case reveals the possibility of the localization of malignant cells within bone metaplasia of intraocular ossification in an enucleated blind painful eye. From a practical point of view, a careful systematic histopathological examination of all resected tissues in patients with a history of malignant neoplastic pathology is necessary to confirm the diagnosis and exclude occult malignancies.

Orbital metastases from breast cancer: A single institution case series.

BACKGROUND AND OBJECTIVES: Among orbital tumors, metastatic lesions have a prevalence of 1% to 13%; on the other hand, breast cancer is the most common malignancy causing orbital metastases. The aim of this study is to present our experience dealing with orbital metastases caused by breast cancer, to assess characteristics and clinic-pathological data of patients suffering from this rare occurrence and to find indexes related with their prognosis and survival. METHODS: Records of 28 patients diagnosed with orbital metastases from breast cancer at the Department of Ophthalmology, Humanitas Clinical and Research Centre of Milano over a 27-year period (1992-2018) were retrieved and analyzed. RESULTS: Mean patients' age at breast cancer diagnosis was 56.29 ± 14.63 years. Mean time interval between breast cancer diagnosis and orbital metastasis occurrence was 5 ± 4.17 years. All lesions were estrogen receptor-positive; 79% of patients harbored progesterone receptor-positive lesions. Interestingly, the majority of deceased patients presented orbital lesions with MIB-1 index >50% (P = .0265) and had concomitant lung metastases (P = .0452). CONCLUSIONS: The occurrence of orbital metastasis from breast cancer represents a challenging finding. Patients' clinical picture can include exophthalmos, edema, tumefaction, proptosis and/or diplopia. Significant symptomatic improvement can be achieved through surgery and other adjuvant treatments, such as radiation therapy and chemotherapy.

Intraoperative sonography for nonpalpable breast lesions: Additional indications for a consolidate technique.

This prospective study evaluated the intraoperative ultrasound scan (IUSS) for nonpalpable breast lesions' detection. A total of 108 consecutive female patients underwent surgery using IUSS: Frozen sections demonstrated clear margins in 95.5% of neoplastic patients. Only four (4.5%) patients underwent local re-excision in the same operation. IUSS demonstrated to be quick, accurate, useful, effective, and safe for the intraoperative management of neoplastic nonpalpable breast lesions when performed by a surgeon who has undergone US training, particularly for people in whom alternative approaches can show some limitations due to contraindications or because of scheduling constraints, costs, and patient discomfort.
