Objective: Assessing patient satisfaction is an important component of understanding a program's efficacy and quality. The purpose of this study is to evaluate patient satisfaction with a teleophthalmology program tailored for ocular oncology that provides screening, remote assessment, care planning, and follow-up.

Study design: Retrospective survey.

Methods: An adapted version of the Telehealth Satisfaction Scale, consisting of the 8 questions plus 5 additional questions specific to the teleophthalmology program, was used to survey patients. The teleophthalmology program involves diagnostic imaging, remote physician assessments, and follow-up phone calls from health care team members to deliver results to patients. For reporting, the Consensus-Based Checklist for Reporting of Survey Studies was used. T-tests explored satisfaction differences across demographics and teleophthalmology visits.

Results: Among the 95 patients contacted, 91 agreed to participate in the survey (96% response rate). Participants exhibited high overall satisfaction with the teleophthalmology program, reflected in a mean Telehealth Satisfaction Scale score of 28.88 (SD = 3.35 of 32). The median number of teleophthalmology visits completed was 4.0 (range of 1-8 appointments). No significant differences in satisfaction were found on the basis of age (P = 0.56), urban or rural residence (P = 0.17), or the number of telemedicine appointments (P = 0.51).

Conclusions: This analysis displays high satisfaction levels among patients within an ocular oncology clinic participating in the current telemedicine program, irrespective of age, geography, or number of teleophthalmology visits. Participants reported having their health care needs met with minimal clinical encounters due to remote consultations and telephone communications.

Objective: To investigate the incidence of intraoperative floppy iris syndrome (IFIS) in patients with pseudoexfoliation syndrome (PXF) and analyze preoperative ocular predicting factors.

Design: A retrospective case-control study METHODS: The study included 224 eyes with PXF and 287 control eyes without PXF. One eye per patient, who underwent cataract surgery at the Wolfson Medical Center between January 2020 to December 2021, was included. Medical records of the patients were reviewed. Data collected included demographic characteristics, medical history, preoperative comprehensive ophthalmic examination, biometry, surgical procedure details, and IFIS occurrence. The association of IFIS with preoperative ocular parameters was analyzed through both univariant and multivariant analyses.

Results: Patients with PXF were older and had a higher prevalence of glaucoma (77.6 ± 6.4 years vs 74.2±7.6 years; p < 0.001, and 20.1 % vs 9.8 %, p < 0.001, respectively). Prevalence of α-blockers treatment was similar in both groups. IFIS rate among the PXF group was 12.5% (n = 28) compared to 7.3% (n = 21) in the control group (p < 0.05). When omitting patients exposed to α-blockers, the PXF group exhibited a significantly higher IFIS rate (9.9% vs 4.8%; p < 0.05). Pupil dilation diameter was significantly lower among PXF patients (5.8 ± 1.1 mm vs 6.9 ± 0.99 mm; p < 0.001). Biometric evaluation revealed significant differences in anterior segment depth (ACD) and lens thickness (LT). Multivariate analysis indicated that PXF and decreased mydriatic pupil size remained significant predictors of IFIS.

Conclusion: This study establishes an association between PXF and an increased risk of IFIS during cataract surgery, independent of α-blockers treatment.

Objective: Reoperation for congenital ptosis has added morbidity. The purpose of the current study was to examine the risk for redo ptosis surgery in patients with congenital ptosis, as well as to find predictive factors for reoperation.

Methods: This is a retrospective, cohort study. Analysis of all patients with congenital ptosis who underwent their first ptosis correction surgery between 2012 and 2021 at Sheba Medical Center was performed.

Results: Sixty patients (36 male and 24 female) underwent ptosis surgery for congenital ptosis Twenty nine patients (48.33%) underwent frontalis sling (FS), 13 patients (21.67%) underwent levator muscle (LM) surgeries, 9 patients received levator resection (LR), 4 patients received external levator advancement (LAA), and 18 patients (30%) underwent Müller's muscle-conjunctival resection (MMCR). Eighteen patients (30%) underwent a second ptosis surgery. The unadjusted risk of second ptosis surgery was almost four-fold among males with ptosis relative to females with ptosis (HR, 3.90; 95% CI, 3.67-547; p = 0.033) and higher among younger individuals (HR, 4.23; 95% CI, 3.33-5.62; p = 0.042). Older age was protective against the risk of second ptosis surgery (adjusted OR, 0.50; 95% CI, 0.21-0.60; p < 0.001), whereas male sex was associated with an increased likelihood of second ptosis surgery (adjusted OR, 3.33; 95% CI, 1.64-3.98; p < 0.001).

Conclusions: An increased risk of failure of the first surgery was found among male patients, younger patients, and patients with more severe ptosis before the first surgery. Awareness of those factors is beneficial for clinicians and parents.

High-resolution optical coherence tomography (HR-OCT) has transformed the diagnosis and management of ocular surface lesions. Providing a detailed cross-sectional view of the cornea and conjunctiva, HR-OCT can be used to identify characteristic features of various benign and malignant ocular surface lesions, aiding in their diagnosis and guiding treatment. When incorporated into an ophthalmology clinic, HR-OCT provides morphological images of lesions in a noninvasive means, akin to an "optical biopsy". The characteristic HR-OCT features of several lesions have been well described in the literature, including for ocular surface squamous neoplasia, papilloma, melanoma, primary acquired melanosis, complexion associated melanosis, nevus, pterygium, pinguecula, lymphoma, and amyloidosis. HR-OCT can be used to differentiate between lesions with similar clinical features, lesions that co-exist on the same ocular surface, and atypically presenting lesions, such as pigmented ocular surface squamous neoplasia or amelanotic melanoma. The management of ocular surface lesions has been transformed by the implementation of HR-OCT, providing clinicians with the ability to monitor tumor response to topical chemotherapies, follow previously excised lesions for recurrence, and map out tumor borders intraoperatively. While there are some limitations to HR-OCT, including imaging of thick or deep lesions, it has become an essential tool for ocular oncologists in the management of ocular surface lesions.

Objective: Amblyopia has been shown to slow reading speed. Limited literature exists on reading speed in strabismus without amblyopia. Our study compares binocular reading speed in patients with strabismus without amblyopia versus normal controls.

Methods: We conducted a prospective study with 48 participants: 12 childhood-onset (onset <8 years of age) strabismus without amblyopia and 36 age- and education level-matched controls. Inclusion criteria were age 14-50 years, education >9 years, primary language English, best-corrected visual acuity >20/30 distance, and >N8 near either eye. Exclusion criteria were presence of other eye pathology or neurologic/cognitive conditions that may affect reading and previous treatment for strabismus/amblyopia. International Reading Speed Texts were used for binocular reading speed assessment. Each participant read 2 passages (passage 1 and 8), following all International Reading Speed Texts instructions. Reading time was measured using a stopwatch. Reading speed was calculated in words per minute (WPM).

Results: Mean age for the strabismus group was 28.3 ± 11.1 and for the control group was 28.2 ± 11.0 years (P = 0.96). Mean education level for strabismus group was 14.2 ± 2.4 and control group was 13.8 ± 2.5 years (P = 0.62). Mean binocular reading speed for passage 1 for strabismus group was 192.0 and for control group was 220.0 WPM (P = 0.01). Mean binocular reading speed for passage 8 for strabismus group was 201.3 and for control group was 226.2 WPM (P = 0.04).

Conclusions: Patients with strabismus (without amblyopia) had slower binocular reading speed compared with controls. Further studies with eye tracking may provide more information. Strabismus, even without amblyopia, may affect reading performance and consequently vision-related quality of life.

Objective: Treatment of palpebral conjunctival lesions is problematic due to late diagnosis, difficult surgical approach, and the need to preserve eyelid integrity. We describe our treatment experience using plaque brachytherapy in the "sandwich technique."

Design: A retrospective study.

Participants: We reviewed the medical records of patients treated by plaque brachytherapy for conjunctival lesions at the Hadassah Medical Center between January 1, 2013, and January 1, 2024, and included in the analysis patients treated for palpebral conjunctival lesions.

Methods: Ruthenium plaque was sutured to the palpebral conjunctiva. The matching nonradioactive "dummy" plaque was sutured to the external eyelid to flip the tarsal's curvature.

Results: The study cohort included 5 patients, 2 men (40%) and 3 women (60%) at a median age of 68.11 years (range: 47-79.7 years). Three patients had conjunctival melanoma (60%), 1 had sebaceous carcinoma (20%), and 1 had extensive carcinoma in situ (20%). All lesions were in the left upper eyelid. Median follow-up was 37.6 months (range: 18.7-110.6 months). Four patients demonstrated a complete response (80%), while one had a partial response (20%). There was local recurrence in 1 patient (20%), and 1 patient had new foci elsewhere (20%). All patients had full local control after adding local treatments. One patient developed metastatic disease and died (20%). All patients had manageable madarosis and conjunctival scars.

Conclusions: Treatment of palpebral conjunctival lesions using "sandwich" plaque brachytherapy is safe and effective. To the best of our knowledge, this treatment was never described before, and we believe it should be added to our armamentarium.

Objective: This study aims to delineate the key characteristics of eyelid neoplasms in central and southern coastal China and to explore potential factors affecting tumour development.

Methods: This was a retrospective, multicentre observational study. In total, 1302 cases of eyelid neoplasms diagnosed in 2 tertiary hospitals were reviewed from January 2013 to May 2023. Histogenesis, pathologic diagnosis, and potential risk factors were investigated, and the findings were compared with data from various regions and countries. Age- and sex-specific incidence rates, time trends, distributions across age groups, and the relationship with the Sociodemographic Index, latitude, and altitude were calculated.

Results: There were 1162 benign (89.2%) and 140 malignant (10.8%) cases, representing 63 pathologic types. The median age of benign cases (50 years) was significantly lower than that of malignant cases (72 years) (P < 0.05). The most common benign and malignant lesions were intradermal nevus (28.83%) and basal cell carcinoma (BCC) (74.29%). A relatively younger median age (68 years) for sebaceous gland carcinoma (SGC) was observed, with a male preponderance (sex ratio 2:1). Analyses of the proportions of BCC, SGC, and squamous cell carcinoma in eyelid malignancies revealed significant regression equations (P < 0.05).

Conclusions: Most eyelid neoplasms are of epithelial and melanocytic origin, with benign tumours being predominant. The regions with greater Sociodemographic Index exhibit a greater incidence of BCC and a lower incidence of squamous cell carcinoma and SGC. BCC appears to have a greater incidence in regions located at higher latitudes.
