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.

Abstract
Purpose To report a case of high-risk human papillomavirus (HPV)-associated corneal/conjunctival intraepithelial neoplasia (CIN) in a 17-year-old fair-skinned male with no other risk factors. Observations A 17-year-old Caucasian male presented with an 18-month history of left eye pain, redness, itchiness, and decreased vision. Examination revealed a leukoplakic nasal limbal/peripheral corneal lesion resistant to topical antibiotic and anti-inflammatory treatments. Excisional biopsy confirmed the diagnosis of CIN, and RNA in situ hybridization testing for high-risk HPV types 16/18 was positive. Subsequent testing of the patient for human immunodeficiency virus (HIV) returned negative. Conclusions and Importance The median age of CIN diagnosis in the United States is in the sixth decade of life and is usually associated with a history of ultraviolet (UV) light exposure. There are reports of CIN in young patients with systemic immunodeficiency, immunosuppression, xeroderma pigmentosum, atopic dermatitis, asthma, and vaping. Here we present a case of high-risk HPV-associated CIN in a young, fair-skinned patient with no other identifiable risk factors.

[PMID: 37501105 PMCID: PMC10373405 DOI: 10.1186/s12886-023-03092-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/18/2022] [Accepted: 07/20/2023] [Indexed: 07/29/2023] Open
Abstract
PURPOSE Ocular surface squamous neoplasia (OSSN) comprises a wide spectrum of squamous tumors, from which corneal/conjunctival intraepithelial neoplasia (CIN) is the most common one. The classic treatment is complete excision, but recurrence rates are high. Antineoplastic drugs such as mitomycin C (MMC) and interferon alpha 2b (IFNα2b) have been used as adjuvants or as primary treatment. To evaluate the efficacy and safety of topical IFNα2b and MMC in patients with CIN, a phase IIb double-blind clinical trial was performed. METHODS Patients diagnosed with localized CIN were evaluated by slit lamp and impression cytology and were randomly given MMC 0.04% or INF2b (1 million IU/mL) 4 times daily until neoplasia resolution. Time of resolution and frequency of adverse effects were analyzed to determine the pharmacological efficacy and safety of both medications. RESULTS Seventeen patients were included. Nine patients were treated with MMC and 8 with IFNα2b. All patients responded to treatment. The resolution time in days was 59.11 ± 24.02 in patients treated with MMC and 143.50 ± 47.181 in those treated with IFNα2b (p < 0.001). In the MMC group, one recurrence was reported (11%). There were no recurrences at 2 years of follow-up in the IFNα2b group. Regarding adverse effects, one or more mild adverse reaction occurred in 77% of patients managed with MMC and in 50% of patients managed with IFNα2b (p > 0.05). No serious adverse effects were reported. CONCLUSIONS Topical chemotherapy with MMC and IFNα2b demonstrate pharmacological safety and efficacy. Therefore, these drugs could be considered as primary therapies for localized CIN .

Abstract
The ocular surface, comprised of the corneal and conjunctival epithelium, innervation system, immune components, and tear-film apparatus, plays a key role in ocular integrity as well as comfort and vision. Gene defects may result in congenital ocular or systemic disorders with prominent ocular surface involvement. Examples include epithelial corneal dystrophies, aniridia, ectrodactyly-ectodermal dysplasia-clefting (EEC) syndrome, xeroderma pigmentosum (XP), and hereditary sensory and autonomic neuropathy. In addition, genetic factors may interact with environmental risk factors in the development of several multifactorial ocular surface disorders (OSDs) such as autoimmune disorders, allergies, neoplasms, and dry eye disease. Advanced gene-based technologies have already been introduced in disease modelling and proof-of-concept gene therapies for monogenic OSDs. For instance, patient-derived induced pluripotent stem cells have been used for modelling aniridia-associated keratopathy (AAK), XP, and EEC syndrome. Moreover, CRISPR/Cas9 genome editing has been used for disease modelling and/or gene therapy for AAK and Meesmann's epithelial corneal dystrophy. A better understanding of the role of genetic factors in OSDs may be helpful in designing personalized disease models and treatment approaches. Gene-based approaches in monogenic OSDs and genetic predisposition to multifactorial OSDs such as immune-mediated disorders and neoplasms with known or possible genetic risk factors has been seldom reviewed. In this narrative review, we discuss the role of genetic factors in monogenic and multifactorial OSDs and potential opportunities for gene therapy.

Abstract
Given the various ocular manifestations of limbal stem cell insufficiency, an awareness of the genetic, acquired, and immunological causes and associated additional treatments of limbal stem cell deficiency (LSCD) is essential for providers. We performed a comprehensive review of the literature on the various etiologies and specific therapies for LSCD. The resources utilized in this review included Medline (PubMed), Embase, and Google Scholar. All English-language articles and case reports published from November 1986 through to October 2022 were reviewed in this study. There were collectively 99 articles on these topics. No other exclusion criteria were applied. Depending on the etiology, ocular manifestations of limbal stem cell deficiency range from dry eye syndrome and redness to more severe outcomes, including corneal ulceration, ocular surface failure, and vision loss. Identifying the source of damage for LSCD is critical in the treatment process, given that therapy may extend beyond the scope of the standard protocol, including artificial tears, refractive surgery, and allogeneic stem cell transplants. This comprehensive review of the literature demonstrates the various genetic, acquired, and immunological causes of LSCD and the spectrum of supplemental therapies available.

Abstract
AIM We aimed to evaluate the effectiveness of optical coherence tomography (OCT) in the differential diagnosis of anterior segment diseases such as ocular surface squamous neoplasia (OSSN) and pterygium. METHODS Patients who were pre-diagnosed with either OSSN (21) or pterygium (19) between January 2020 and November 2022 were included in this retrospective study. Anterior segment photographs and anterior segment optical coherence tomography (AS-OCT) measurements were obtained from each patient. Excisional or incisional biopsy materials underwent pathological evaluation. RESULTS Preoperative AS-OCT images of the patients with OSSN showed similarities with histopathological specimens. Both ocular and pathological specimens appeared to have a thicker epithelial layer with a distinct change from healthy to neoplastic epithelium. Preoperative AS-OCT images of individuals with pterygium were also comparable with histopathological samples. Both pathological and AS-OCT images of the pterygium patients showed a normal thickness epithelium and a thickened subepithelial layer under the epithelium. The mean epithelial thickness measured with AS-OCT in OSSN patients was found to be 295.3 ± 111.3 µm, while it was 80.7 ± 43.4 µm in pterygium patients. The difference was statistically significant (P<0.001). The receiver operating characteristic (ROC) curve analysis revealed a cut-off value of 97 µm for the differential diagnosis of OSSN from pterygium, with a sensitivity of 100% and specificity of 94.7%. CONCLUSIONS AS-OCT can be used as a noninvasive diagnostic tool for the evaluation of ocular surface lesions. Its ability to distinguish between OSSN and pterygium is demonstrated by the statistically significant difference in epithelial thickness and the significant morphological association with histopathological findings.

Abstract
Corneal stem/progenitor cells are typical adult stem/progenitor cells. The human cornea covers the front of the eyeball, which protects the eye from the outside environment while allowing vision. The location and function demand the cornea to maintain its transparency and to continuously renew its epithelial surface by replacing injured or aged cells through a rapid turnover process in which corneal stem/progenitor cells play an important role. Corneal stem/progenitor cells include mainly corneal epithelial stem cells, corneal endothelial cell progenitors and corneal stromal stem cells. Since the discovery of corneal epithelial stem cells (also known as limbal stem cells) in 1971, an increasing number of markers for corneal stem/progenitor cells have been proposed, but there is no consensus regarding the definitive markers for them. Therefore, the identification, isolation and cultivation of these cells remain challenging without a unified approach. In this review, we systematically introduce the profile of biological characterizations, such as anatomy, characteristics, isolation, cultivation and molecular markers, and clinical applications of the three categories of corneal stem/progenitor cells.

Abstract
In-situ hybridization provides a convenient and reliable method to detect human papillomavirus (HPV) infection in formalin-fixed paraffin-embedded tissue. Cases of conjunctival papillomas, conjunctival intraepithelial neoplasia (CIN), conjunctival carcinoma in situ (cCIS), and invasive squamous cell carcinoma (SCC), in which low-risk (LR) and/or high-risk (HR) HPV types were evaluated by RNA or DNA in-situ hybridization, were retrospectively identified. LR HPV types were frequently detected in conjunctival papillomas (25/30, 83%), including 17/18 (94%) with RNA probes, compared to 8/12 (75%) with DNA probes. None of the CIN/cCIS or SCC cases were positive for LR HPV by either method. HR HPV was detected by RNA in-situ hybridization in 1/16 (6%) of CIN/cCIS cases and 2/4 (50%) of SCC cases, while DNA in-situ hybridization failed to detect HPV infection in any of the CIN/cCIS lesions. Reactive atypia and dysplasia observed in papillomas was generally associated with the detection of LR HPV types. Collectively, our findings indicate RNA in-situ hybridization may provide a high-sensitivity approach for identifying HPV infection in squamous lesions of the conjunctiva and facilitate the distinction between reactive atypia and true dysplasia. There was no clear association between HPV infection and atopy in papillomas or dysplastic lesions.

Abstract
Alcohol (ethanol) has been used in medicine since time immemorial. In ophthalmic practice, besides as an antiseptic, it was given as retrobulbar injections to relieve severe ocular pain. Alcohol can be applied topically to the surface of neoplastic or suspicious lesions to kill cells that might desquamate and seed during surgical excision, to treat epithelial ingrowth that can occur following corneal surgeries, particularly laser in situ keratomileusis (LASIK), and to treat superficial infectious keratitis. In view of its ability to achieve a smooth cleavage plane between the epithelium and the Bowman's layer, alcohol-assisted delamination (ALD) of the corneal epithelium has been used widely and effectively for a variety of diagnostic and therapeutic indications, at times delivering both outcomes. Diagnostically, ALD yields an intact epithelial sheet which can be fixed flat to provide excellent orientation for histopathological evaluation. Therapeutically, it is most commonly used to treat recurrent corneal erosion syndrome, where its efficacy is comparable to that of phototherapeutic keratectomy but with several advantages. It has also been used to treat various forms of epithelial/anterior stromal dystrophies, which can obviate or delay the need for corneal transplantation for several years. In addition, ALD is performed in corneal collagen cross-linking and corneal refractive surgery for relatively atraumatic removal of the epithelium. In this review, we aimed to provide a comprehensive overview of the diagnostic and therapeutic use of topical alcohol in ophthalmology, to describe the surgical and fixation techniques of ALD, and to highlight our experience in ALD over the past decade.

Abstract
Purpose To report the findings of anterior segment optical coherence tomography (AS-OCT) and in vivo confocal microscopy (IVCM) in two patients with peripheral hypertrophic subepithelial corneal degeneration (PHSD). Methods Case series by restrospective chart review and imaging analysis of AS-OCT and IVCM. Results Slit lamp examination of the two patients revealed a bilateral subepithelial-elevated fibrous tissue of the superior-nasal quadrant, as well as inferior-nasal in one of the patients. Best corrected visual acuity ranged from 20/25 to 20/15. AS-OCT showed continuous, homogenous, well-demarked hyperreflective subepithelial band associated with hyperreflectivity in the anterior stroma. IVCM demonstrated normal epithelial cell morphology and arrangement and a fibrous structure subepithelial and in the anterior stroma. Conclusion AS-OCT and IVCM can facilitate the diagnosis of PHSD and differentiate it from other corneal entities that present peripheral opacifications.

Abstract
Recent advances in anterior segment imaging have transformed the way ocular surface squamous neoplasia (OSSN) is diagnosed and monitored. Ultrasound biomicroscopy (UBM) has been reported to be useful primarily in the assessment of intraocular invasion and metastasis. In vivo confocal microscopy (IVCM) shows enlarged and irregular nuclei with hyperreflective cells in OSSN lesions and this has been found to correlate with histopathology findings. Anterior segment optical coherence tomography (AS-OCT) demonstrates thickened hyperreflective epithelium with an abrupt transition between abnormal and normal epithelium in OSSN lesions and this has also been shown to mimic histopathology findings. Although there are limitations to each of these imaging modalities, they can be useful adjunctive tools in the diagnosis of OSSN and could greatly assist the clinician in the management of OSSN patients. Nevertheless, anterior segment imaging has not replaced histopathology's role as the gold standard in confirming diagnosis.

Abstract
Limbal stem cell deficiency (LSCD) is a pathologic condition caused by the dysfunction and/or destruction of stem cell precursors of the corneal epithelium, typified clinically by corneal conjunctivalization. The purpose of this review is to critically discuss a less well-known cause of limbal stem cell disease: contact lens (CL) wear. A literature search was conducted to include original articles containing patients with CL-induced LSCD. This review describes epidemiology, diagnostic strategies, pathogenesis, differential diagnosis, and treatment modalities for this condition.

Recurrence of Ocular Surface Squamous Neoplasia Treated With Excisional Biopsy and Cryotherapy. Am J Ophthalmol 2015; 160:213-219.e1. [PMID: 25914042 DOI: 10.1016/j.ajo.2015.04.027] [Citation(s) in RCA: 20] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/27/2015] [Revised: 04/17/2015] [Accepted: 04/20/2015] [Indexed: 11/22/2022]
Abstract
PURPOSE To evaluate the recurrence rate of ocular surface squamous neoplasias (OSSN) after excision and cryotherapy in an academic cornea practice and to determine factors associated with recurrence. DESIGN Retrospective interventional case series. METHODS All cases of OSSN from 1998 through 2013 that were treated with excisional biopsy and adjunctive cryotherapy were retrospectively reviewed. Clinical characteristics upon presentation including size of lesion, location, and atypical features were noted. All recurrences of OSSN after excision and cryotherapy were noted and categorized in relation to clinical characteristics, pathologic grade, and margin involvement. RESULTS Forty-three cases of OSSN from 42 patients were analyzed with a median follow-up of 29 months. A total of 32.6% of subjects had dysplasia and 67.4% had squamous cell carcinoma (SCC). A total of 83.7% of subjects had both corneal and conjunctival involvement while 16.3% had conjunctival involvement only. Overall, 3 recurrences were observed, all of which had margin involvement; nonetheless, the majority of incompletely excised OSSN (25/28) showed no recurrence. The recurrence rate at 6 months was 2.3%. Recurrence at 1 year, 2 years, and 5 years remained stable at 7.1%. CONCLUSIONS Excision with cryotherapy is an effective treatment for the majority of OSSN cases, even among cases with pathologic evidence of tumor at the margin, with an overall recurrence rate of 7.1% at 1 year, 2 years, and 5 years.

Abstract
The development of optical coherence tomography (OCT) technology has helped to usher in a new era of in vivo diagnostic imaging of the eye. The utilization of OCT for imaging of the anterior segment and ocular surface has evolved from time-domain devices to spectral-domain devices with greater penetrance and resolution, providing novel images of anterior segment pathology to assist in diagnosis and management of disease. Ocular surface squamous neoplasia (OSSN) is one such pathology that has proven demonstrable by certain anterior segment OCT machines, specifically the newer devices capable of performing ultra high-resolution OCT (UHR-OCT). Distinctive features of OSSN on high resolution OCT allow for diagnosis and differentiation from other ocular surface pathologies. Subtle findings on these images help to characterize the OSSN lesions beyond what is apparent with the clinical examination, providing guidance for clinical management. The purpose of this review is to examine the published literature on the utilization of UHR-OCT for the diagnosis and management of OSSN, as well as to report novel uses of this technology and potential directions for its future development.

Abstract
Ocular surface squamous neoplasia is a rare complication after a kidney transplant, related with increased risk and poor prognosis. Generally, ocular surface squamous neoplasia in kidney transplant patients is associated with skin lesions. We report a case of ocular surface squamous neoplasia without skin lesions in a kidney transplant recipient. Systematic periodic ophthalmic evaluation of recipients may help ensure the early diagnosis of subtle ocular surface squamous neoplasia.

Abstract
PURPOSE To describe the clinical and histologic characteristics of ocular surface squamous neoplasia (OSSN) lesions and provide clinicopathologic correlation to determine clinical features that may indicate higher-grade lesions. DESIGN Retrospective case series. PARTICIPANTS A total of 612 consecutive OSSN lesions sent to the Bascom Palmer ocular pathology laboratory from January 1, 2001 to September 20, 2010. METHODS Pathologic examination of lesions by a single experienced ocular pathologist (S.R.D.). Review of pathology records and patient charts. MAIN OUTCOME MEASURES Correlation of clinical factors and histology of higher-grade OSSN. RESULTS Over the studied period, 33% of submitted specimens were characterized as mild, moderate, or severe dysplasia; 52% were classified as carcinoma in situ; and 11% were graded as squamous cell carcinoma. Characteristics associated with higher-grade OSSN lesions included male gender, biopsy at Bascom Palmer Eye Institute, temporal and superior locations, lack of corneal involvement, papillomatous and nodular appearance, microscopic multifocality, and positive margins on biopsy. CONCLUSIONS Certain clinical factors are associated with higher-grade histologic lesions. These findings may help clinicians more accurately evaluate and anticipate the pathologic grade of conjunctival and corneal lesions suspected to be OSSN.

Abstract
PURPOSE To identify predictors of ocular surface squamous neoplasm (OSSN) recurrence after operative resection. DESIGN Retrospective case series. PARTICIPANTS Three hundred eighty-nine consecutive patients who underwent excisional biopsy for OSSN lesions at the Bascom Palmer Eye Institute from January 1, 2001, to September 20, 2010. METHODS Review of pathology records and patient charts. MAIN OUTCOME MEASURES Identification of factors predictive of OSSN recurrence. RESULTS Of 389 excised OSSN lesions, 44 recurred during follow-up. The 1-year recurrence rate was 10% and the 5-year recurrence rate was 21%, with a mean time to recurrence in those with a recurrence of 2.5 years (standard deviation, 3.4). Using the American Joint Committee on Cancer (AJCC) clinical staging system, T3 and T2 lesions portended a higher risk of recurrence compared with T1 (T2/T1 hazard ratio [HR], 2.05 [P = 0.04]; T3/T1 HR, 2.31 [P = 0.07]). In addition, a location characteristic that increased the risk of tumor recurrence was tarsal involvement (AJCC T3 stage lesion; HR, 4.12; P = 0.007). Nasal location was associated with a decreased risk of tumor recurrence (HR, 0.41; P = 0.008). Pathologic characteristics significantly associated with tumor recurrence were the presence of positive margins (HR, 2.73; P = 0.008) and higher grade lesions (carcinoma in situ and squamous cell carcinoma versus dysplasia; HR, 2.55; P = 0.02). Treatment with adjuvant cryotherapy significantly decreased the risk of tumor recurrence (HR, 0.51; P = 0.03). In those patients with positive margins, the use of postoperative topical interferon therapy lowered the recurrence rate to a level similar to that of patients with negative margins. CONCLUSIONS Certain patient and tumor factors are associated with a higher risk of OSSN recurrence after operative excision, such as tarsal tumor location and positive surgical margins. Postoperative adjuvant therapy should be considered in patients with high-risk OSSN characteristics.
