[PMID: 34765812 PMCID: PMC8579786 DOI: 10.4103/2452-2325.329089] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/24/2020] [Revised: 03/15/2021] [Accepted: 03/18/2021] [Indexed: 11/04/2022] Open
Abstract
Purpose To investigate the effects of topical and perilesional interferon alpha-2b as primary treatment for ocular surface squamous neoplasia (OSSN). Methods In this prospective interventional case series, topical interferon alpha-2b (3 MIU/mL) was used as the initial treatment of OSSN, with perilesional interferon alpha-2b (3 MIU/mL) added based on clinical response. The primary outcome was complete tumor resolution. Spearman's rank correlation test was used to investigate the association of complete tumor resolution and time to resolution with baseline tumor characteristics and the American Joint Committee on Cancer (AJCC) classification for OSSN. Results Ninety-two patients (92 OSSN tumors) were included in the study. The total follow-up duration was 13.57 ± 2.14 months (median: 12, range: 3-23). The median basal tumor diameter was 4 mm (mean: 4.13 ± 1.37). Complete tumor resolution was achieved in 89 cases (96.73%), with a median time to complete tumor resolution of 5 months (mean: 4.64 ± 1.92). Complete tumor resolution was 57 of 57 in T1 (100%), 8 of 9 in T2 (88.88%), and 21 of 23 in T3 (91.30%). There were statistically significant correlations between AJCC classification and complete tumor resolution (Spearman's r = -0.22, P = 0.03) and maximal basal tumor diameter and the time to complete resolution (Spearman's r = 0.35, P = 0.001). There were no recurrences during the study follow-up period. Conclusion Topical interferon alpha-2b is effective and well tolerated as a primary treatment for OSSN, with a high rate of tumors responding completely to therapy.

Abstract
The onset of scleral necrosis after ocular surgery may have catastrophic ocular and systemic consequences. The two most frequent surgeries causing surgically-induced scleral necrosis (SISN) are pterygium excision and cataract extraction. Several pathogenic mechanisms are involved in surgically induced scleral necrosis. All of them are poorly understood. Ocular trauma increasing lytic action of collagenases with subsequent collagen degradation, vascular disruption leading to local ischemia, and immune complex deposition activating the complement system represents some of the events that lead to scleral necrosis. The complex cascade of events involving different pathogenic mechanisms and the patient's abnormal immune response frequently leads to delayed wound healing that predisposes the development of scleral necrosis. The management of SISN ranges from short-term systemic anti-inflammatory drugs to aggressive immunosuppressive therapy and surgical repair. Therefore, before performing any ocular surgery involving the sclera, a thorough ophthalmic and systemic evaluation must be done to identify high-risk patients that may develop SISN.

Abstract
Purpose To compare the effectiveness of onion extract, topical steroid, and petrolatum emollient in the prevention of scars in cases who underwent bilateral upper eyelid blepharoplasty. Methods A prospective, interventional, comparative, double-blinded case series was designed on cases who underwent upper lid blepharoplasty. After suture removal (1 week following the surgery), the eyelids of participants were randomly allocated into the three groups: The first group used onion extract on the right eyelids (n = 18), and the second group used topical steroid on the right eyelids (n = 19). In the third group, the control group, petrolatum emollient was used on the left eyelids (n = 37) of the first and second group's cases. They used drugs for 2 months and were evaluated by the Manchester Scar Scale (MSS) objectively by two graders who were blinded to the type of medication. MSS evaluates five different characteristics of the scar in addition to the Visual Analog Scale (VAS). These characteristics include color, distortion, contour, texture, and transparency. VAS scores the overall scar appearance which ranged among 0-10. The sum of the scores for the five different parameters, and VAS was calculated, analyzed, and compared among the groups. Results A total of 37 cases (74 eyelids) who underwent bilateral upper blepharoplasty were included. The mean ± standard deviation (SD) of age was 51.94 ± 9.26 years, 49.40 ± 9.37 years, and 47.00 ± 9.06 years in the onion extract, topical steroid, and petrolatum emollient groups, respectively (P = 0.275). There were no statistically significant differences in the mean ± SD of the sum of the MSS scores among the three groups (P = 0.924) or between the onion extract and topical steroid groups (P = 0.951). Furthermore, the color, distortion, contour, texture, transparency, and VAS scores were not statistically significantly different among the three groups or between the onion extract and topical steroid groups (P > 0.05). Conclusion There were no significant differences among these three groups of drugs regarding the appearance of the upper blepharoplasty scar.

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.

Abstract
Two cases of biopsy-proven conjunctival squamous cell carcinoma (SCC) that developed local and regional spread are described. The cases involved a 65-year-old woman and a 79-year-old man who were initially treated at outside institutions for SCC of the conjunctiva. The patients did not have a history of immune compromise. The female patient presented with direct extension into the lacrimal gland but deferred recommended exenteration. Despite eventual exenteration, she developed metastasis to a neck node 6 months later, which was treated with radiotherapy. The male patient presented with local recurrence and a parotid node metastasis treated with exenteration, parotidectomy, selective neck dissection, and postoperative radiotherapy. Review of the outside pathology of both cases revealed positive tumor margins at the time of original resection. Local control of conjunctival SCC is of critical importance to reduce the risk of orbital extension and regional spread.

Abstract
PURPOSE The objective of this study was to compare the cost associated with surgical versus interferon-alpha 2b (IFNα2b) treatment for ocular surface squamous neoplasia (OSSN). DESIGN A matched, case-control study. PARTICIPANTS A total of 98 patients with OSSN, 49 of whom were treated surgically and 49 of whom were treated medically. METHODS Patients with OSSN treated with IFNα2b were matched to patients treated with surgery on the basis of age and date of treatment initiation. Financial cost to the patient was calculated using 2 different methods (hospital billing and Medicare allowable charges) and compared between the 2 groups. These fees included physician fees (clinic, pathology, anesthesia, and surgery), facility fees (clinic, pathology, and operating room), and medication costs. Time invested by patients was calculated in terms of number of visits to the hospital and compared between the 2 groups. Parking costs, transportation, caregiver wages, and lost wages were not considered in our analysis. MAIN OUTCOME MEASURES Number of clinic visits and cost of therapy as represented by both hospital charges and Medicare allowable charges. RESULTS When considering cost in terms of time, the medical group had an average of 2 more visits over 1 year compared with the surgical group. Cost as represented by hospital charges was higher in the surgical group (mean, $17 598; standard deviation [SD], $7624) when compared with the IFNα2b group (mean, $4986; SD, $2040). However, cost between the 2 groups was comparable when calculated on the basis of Medicare allowable charges (surgical group: mean, $3528; SD, $1610; medical group: mean, $2831; SD, $1082; P = 1.00). The highest cost in the surgical group was the excisional biopsy (hospital billing $17 598; Medicare allowable $3528), and the highest cost in the medical group was interferon ($1172 for drops, average 8.0 bottles; $370 for injections, average 5.4 injections). CONCLUSIONS Our data in this group of patients previously demonstrated equal efficacy of surgical versus medical treatment. In this article, we consider costs of therapy and found that medical treatment involved two more office visits, whereas surgical treatment could be more or equally costly depending on insurance coverage.

Topical Mitomycin-C enhances subbasal nerve regeneration and reduces erosion frequency in the debridement wounded mouse cornea. Exp Eye Res 2015; 146:361-369.

Abstract
Corneal epithelial basement membrane dystrophies and superficial injuries caused by scratches can lead to recurrent corneal erosion syndrome (RCES). Patients and animals with reduced corneal sensory nerve innervation can also develop recurrent erosions. Multiple wild-type mouse strains will spontaneously develop recurrent corneal erosions after single 1.5 mm debridement wounds. Here we show that this wound is accompanied by an increase in corneal epithelial cell proliferation after wound closure but without a commensurate increase in corneal epithelial thickness. We investigated whether excess corneal epithelial cell proliferation contributes to erosion formation. We found that topical application of Mitomycin C (MMC), a drug used clinically to improve healing after glaucoma and refractive surgery, reduces erosion frequency, enhances subbasal axon density to levels seen in unwounded corneas, and prevents excess epithelial cell proliferation after debridement wounding. These results suggest that topically applied MMC, which successfully reduces corneal haze and scarring after PRK, may also function to enhance subbasal nerve regeneration and epithelial adhesion when used to treat RCES.

Chonnam Med J 2015; 51:19-25.

Abstract
The current study aimed to determine the efficacy of probing with adjunctive mitomycin C (MMC) as a treatment for nasolacrimal duct obstruction (NLDO) in adults and to study the association of probing success with demographic and obstruction characteristics. This was a prospective, randomized, double-blind, placebo-controlled trial including 140 patients (each with a unilateral NLDO) scheduled for nasolacrimal probing who were randomly assigned to receive MMC (0.2 mg/ml, 70 patients; group A) or placebo (normal saline, 70 patients; group B). Irrigation was carried out with 0.5 cc of MMC (0.2 mg/mL) in the duct with a nasal pack for 10 minutes in group A. Patients' postprobing epiphora was evaluated at 2 weeks and 1, 3, 6, and 9 months postoperatively. Probing was judged to be a success if there was no or mild watering for at least 9 months after the procedure. There were no significant differences between the two study groups in demographic characteristics or duration of the operation (p=0.062). The overall success rate of probing with MMC was 47/70 (67.1%), which was significantly higher than the success rate of the procedure with placebo (p=0.0027). When the sex of the patients was controlled for by logistic regression, a significant association between the failure rate of probing and increasing age was found in cases and controls (p=0.004 vs. p=0.006, respectively). No significant side effects of probing with MMC were noted after 9 months of follow-up. Administering MMC in a dosage of 0.2 mg/mL during nasolacrimal probing significantly increased the success rate of probing. The failure rate of probing increased with age. A low dose of MMC is cheap, safe, and easily accessible; thus, it is recommended during nasolacrimal probing, especially in patients who refuse dacryocystorhinostomy surgery.

Abstract
BACKGROUND To report the results of patients undergoing combined excision, cryotherapy, and intraoperative mitomycin-C (EXCRIM) for primary ocular surface squamous neoplasia (OSSN) METHODS: A retrospective review of a non-comparative interventional case series. Histopathologically confirmed primary localized (less than four clock hours) OSSN treated with EXCRIM using adjuvant 0.02 % mitomycin-C (MMC) were included in the study. The main outcome measures were recurrence and complications related to MMC. RESULTS The study enrolled 28 eyes of 28 patients with OSSN with a median age of 64.5 (range 43 to 84) years. The mean tumor size was 6.9 × 4.35 mm. There was corneal involvement in 23 of 28 (82 %). Seven patients (21 %) had delayed epithelial healing. Two of eight patients (25 %) with squamous cell carcinoma (SCC) had positive lateral margins. There were no recurrences over a mean follow-up of 49 months (range 24 to 96). CONCLUSION The excision of OSSN combined with cryotherapy and intraoperative MMC is effective with a low recurrence rate. Long-term follow-up yielded favorable results.
