Abstract
Ocular surface squamous neoplasia (OSSN) is a common eye surface tumour, characterized by the growth of abnormal cells on the ocular surface. OSSN includes invasive squamous cell carcinoma (SCC), in which tumour cells penetrate the basement membrane and infiltrate the stroma, as well as non-invasive conjunctival intraepithelial neoplasia, dysplasia, and SCC in-situ thereby presenting a challenge in early detection and diagnosis. Early identification and precise demarcation of the OSSN border leads to straightforward and curative treatments, such as topical medicines, whereas advanced invasive lesions may need orbital exenteration, which carries a risk of death. Artificial intelligence (AI) has emerged as a promising tool in the field of eye care and holds potential for its application in OSSN management. AI algorithms trained on large datasets can analyze ocular surface images to identify suspicious lesions associated with OSSN, aiding ophthalmologists in early detection and diagnosis. AI can also track and monitor lesion progression over time, providing objective measurements to guide treatment decisions. Furthermore, AI can assist in treatment planning by offering personalized recommendations based on patient data and predicting the treatment response. This manuscript highlights the role of AI in OSSN, specifically focusing on its contributions in early detection and diagnosis, assessment of lesion progression, treatment planning, telemedicine and remote monitoring, and research and data analysis.

Jian H, He W. Clinical features and factors affecting prognosis and partial deterioration of ocular papilloma: a retrospective study of 298 cases. Graefes Arch Clin Exp Ophthalmol 2023; 261:2395-2402. [PMID: 36933010 DOI: 10.1007/s00417-023-06035-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/14/2022] [Revised: 02/28/2023] [Accepted: 03/08/2023] [Indexed: 03/19/2023] Open
Abstract
PURPOSE This study aimed to analyze the clinicopathological features of ocular papilloma, a common benign tumor, and the risk factors related to its recurrence and partial deterioration. METHODS We collected and analyzed the clinical information of 298 patients (51.68% males) with mean age of 41.54 ± 21.95 years, in the ophthalmology department of the West China Hospital. Clinical and pathological factors that might be related to papilloma recurrence and partial deterioration were studied. RESULTS The top three papilloma sites were bulbar conjunctiva, eyelid skin and palpebral conjunctiva. Moreover, 3.59% of lesions presented a malignant transformation, and 16.28% of patients had one or more recurrences after an average follow-up of 4.47 years. The multivariate logistic regression model showed that multiple lesions were a risk factor for recurrence (p = 0.022, OR = 3.088, 95% CI: 1.180-8.079), while cryotherapy decreased the recurrence risk (p = 0.044, OR = 0.364, 95% CI: 0.136-0.972). Additionally, elderly patients and lesions on the corneal limbus or cornea had a higher risk of malignant transformation (p = 0.004 and 0.01, OR = 1.086 and 7.827, 95% CI: 1.027-1.150 and 1.629-37.596, respectively). CONCLUSION Ocular papilloma usually occurs in middle-aged and young patients, with no significant gender differences. Older patients and lesions on the corneal limbus or cornea are risk factors for partial malignant transformation. Finally, multiple lesions were a risk factor for recurrence, and cryotherapy reduced the recurrence rate.

Abstract
BACKGROUND Conjunctival papilloma is often resistant to treatment. Various therapies have been reported with no gold standard. The purpose of this study was to compare treatment outcomes after various therapies. METHODS A retrospective chart review of 30 conjunctival papilloma patients from 2009-2020. Data on demographics, tumour characteristics, primary treatment and outcomes were collected. The primary outcome was the frequency of complete tumour resolution and recurrence rate of each primary therapy. The secondary outcome was treatment related side effects. RESULTS The mean age was 57.5 years (3-93 years) with male predominance (n = 22, 73.3%). Eleven eyes were treated with interferon α-2b (IFN), seven with 5-fluorouracil (5FU), and 10 with excision biopsy and cryotherapy (6 with adjuvant therapy with IFN). The frequency of tumour resolution was 36.4% (4/11), 28.5% (2/7), and 100% (10/10) in each group, respectively. The mean time to resolution was faster in the surgical group compared to the medical group (1 day vs 159 days, p < 0.001). There was higher tumour recurrence with 11% in the surgical vs 0% in the medical group at 6 months and at 12 months, 22% recurrence in the surgical and 0% in the medical group (p = 0.52). However, the differences were not statistically significant. CONCLUSION Papilloma resolution is faster with surgical excision as compared to medical therapy. However, recurrences are more frequent after surgical versus medical treatment.

Abstract
The rise of primary topical monotherapy with chemotherapeutic drugs and immunomodulatory agents represents an increasing recognition of the medical management of ocular surface squamous neoplasia (OSSN), which may replace surgery as the standard of care in the future. Currently, there is no consensus regarding the best way to manage OSSN with no existing guidelines to date. This paper seeks to evaluate evidence surrounding available treatment modalities and proposes an approach to management. The approach will guide ophthalmologists in selecting the most appropriate treatment regime based on patient and disease factors to minimize treatment related morbidity and improve OSSN control. Further work can be done to validate this algorithm and to develop formal guidelines to direct the management of OSSN.

Abstract
Abstract
Purpose
To evaluate clinical characteristics, treatments, and outcomes in patients with ocular surface squamous neoplasia (OSSN) at a tertiary center in Northern Thailand.
Methods
Patients diagnosed with either corneal-conjunctival intraepithelial neoplasia (CIN) or squamous cell carcinoma (SCC) from May 2000 to December 2015, were recruited. The patients’ demographics, symptoms, clinical characteristics, cytopathology, treatments, and outcomes were reviewed.
Results
Overall 171 eyes from 168 patients, 92 eyes were CIN and 79 eyes were SCC. Males were affected in 65.5%. The mean age was 58.8 ± 16.8 (29–99) years. In most cases (60.3%), the tumors were located at the limbus. The most common clinical characteristic was papilliform appearance (46.2%). Human immunodeficiency virus (HIV) infection was found in 37 (22.0%) patients with a mean age of 40.5 ± 7.7 years. The treatments and outcomes were evaluated in 136 eyes whose main initial treatment was wide excision with adjunctive cryotherapy (47.8%), followed by topical mitomycin C (30.9%). The mean follow-up time after treatment was 20.8 ± 2.2 (3–110) months and the recurrence occurred in 18 eyes (13.2%) during the follow-up period. The mean recurrence-free time (months) for CIN was significantly longer than that of SCC (81.3 ± 10.0 [95%CI 61.5 – 101.1] vs 33.2 ± 4.6 [95%CI 24.0 – 42.3], p = 0.030). SCC was the only significant risk factor that influences the recurrence of the tumors with the adjusted hazard ratio of 5.69 (p = 0.005).
Conclusion
OSSN in Northern Thailand usually involved a limbal area and presented as a papilliform mass. HIV infection should be suspected in young patients. CIN had better outcomes after treatments than invasive SCC.

Abstract
Background Conjunctival lesions are common with a wide spectrum of benign, premalignant, and malignant lesions. Few histopathological studies have been conducted on conjunctival lesions with variable designs and results. Our aim in this study is to provide information on common conjunctival lesions seen in an ophthalmology tertiary care center in Saudi Arabia. Methods A retrospective, observational study of all consecutive conjunctival tissue specimens sent for histopathological assessment to the pathology department from 2015 to 2019 were analyzed. Clinical data were collected from medical records, and the histopathological slides were reviewed by a single pathologist. Results A total of 110 conjunctival specimens from 108 patients were included (mean age: 53 years, 67 males and 43 females). Bilateral involvement was mostly found in inflammatory lesions (40%). Most lesions were benign (91%), with a significantly longer duration of symptoms in malignant lesions (p = 0.036*). The clinical diagnosis matched the final histopathological diagnosis in 75.5% of the total specimens. The most frequent category of benign lesions was fibrodegenerative and proliferative lesions (53.6%), with a significantly higher prevalence among adult males (p < 0.001). Melanocytic lesions were more common in children (33.3%) than adults (9.8%), and the mean age of children was significantly lower (p = 0.013). The most frequent malignant lesion was ocular surface squamous neoplasia (50%), with equal prevalence among males and females. The overall outcome was favorable in 89.4% and unfavorable in 10.6%, mostly due to surgical complications, further progression of the lesion, or recurrence. Conclusion This study shows variability in the frequency of conjunctival lesions based on gender, age, geographical, racial, and environmental factors. There has been a shift in the gender-based prevalence of ocular squamous neoplasia over the last three decades, probably due to a change in lifestyle.

Abstract
PURPOSE To report the frequency of conjunctival tumors in the Dominican Republic. METHODS Retrospective noninterventional case series. One hundred thirty-eight consecutive patients with a conjunctival mass evaluated at two tertiary referral centers from 2010 to 2018. Main outcome measures were frequency of tumors by diagnosis and distribution of tumors relative to patients' age and gender. RESULTS The mean age at presentation was 41.2 years (median, 42 years; range 10 days - 91 years). There were 83 male patients (60%) and 55 female patients (40%). The three most common specific diagnoses were junctional, compound, and subepithelial naevi (47 [34%]), squamous cell carcinoma (SCC) (26 [19%]) and conjunctival squamous intraepithelial neoplasia (CIN) (17 [12%]). The mean age at detection was 36.5 years for non-malignant tumors and 56.3 years for malignant tumors (p < .001), with a mean difference of 19.8 years at time of diagnosis (95% CI, 10.7-28.8). Benign tumors were more common in children and young adults; malignant and premalignant tumors were more common in mid and older adults (p = .009). Malignant tumors were more common in males (73%) than in females (27%) (p = .04). CONCLUSION In the Dominican Republic, conjunctival tumors are benign (63%), premalignant (13%) and malignant (24%). Malignant tumors are more common in older adults and men.

Abstract
Conjunctival papilloma is an acquired benign squamous cell tumor that can present at any age, but most frequently in the third and fourth decades of life. Papillomas have been associated with human papilloma virus (HPV) infection, usually types 6 and 11. Although histopathological diagnosis remains the gold standard, the advent of newer non-invasive imaging modalities such as optical coherence tomography (OCT) is transforming the way we diagnose and treat ocular surface tumors, including conjunctival papilloma. Management of these lesions can prove a challenge to the treating physician since not all lesions respond to medical and/or surgical therapy and in fact may worsen after surgical manipulation. In this review, the epidemiology, pathophysiology, clinical characteristics, and diagnosis of conjunctival papilloma including the use of OCT are discussed. Indications, efficacy, and side effects of currently available management options are also reviewed to guide the selection of the best treatment approach.

Abstract
AIM To evaluate the features and outcome of management of malignant conjunctival squamous tumors in King Hussein Cancer Center (a referral tertiary cancer center in the Middle East). METHODS Retrospective case series of 31 eyes for 31 patients with conjunctival squamous neoplasia. Main outcome measures included: age, gender, laterality, tumor location, pathological features, tumor stage, treatment modality, and outcome. RESULTS Twenty (65%) patients were males and median age was 58y. Twenty-two (71%) eyes had the tumor in the nasal quadrant. Tumor invasion to nearby structures was seen in 19 (61%) eyes, including the cornea, fornix, eyelid, and orbit in 17 (55%), 1 (3%), 2 (6%), and 3 (10%) eyes, respectively. Eye salvage was achieved by surgical excision with cryotherapy followed by topical chemotherapy in 28 (90%) eyes, and orbital exenteration was necessary in 3 (10%) eyes due to orbital tumor invasion. Tumor recurrence was seen in 7 (23%) eyes, and the significant predictive factors for recurrence were tumor extension onto the nearby structures (P=0.04), tumor invasiveness (P=0.038), and tumor TNM stage (P=0.031). No significant change in visual acuity was seen, and disease related mortality was 6% (2 patients, both had orbital invasion by invasive squamous carcinoma). CONCLUSION Conjunctival squamous carcinoma is more common in males. Advanced American Joint Committee on Cancer (AJCC) T-stage, tumor local invasion, more pathologically aggressive tumors, and surgical treatment alone (without adjuvant therapy) are associated with higher risk for recurrence, and orbital invasion is the most important poor prognostic factor for metastasis and death. Treatment strategies should be affected by tumor characteristics at presentation.
