Clinicopathologic correlation of ocular surface squamous neoplasia from a university hospital in North Taiwan 1994 to 2014.

BACKGROUND/PURPOSE: To describe the clinical and histologic characteristics of ocular surface squamous neoplasia (OSSN) and evaluate factors significant in recurrence at a university hospital in North Taiwan. METHODS: Patient charts, clinical features, and pathology records were retrospectively reviewed in patients with pathology-proved OSSN from January, 1994 to December, 2014. Clinicopathologic correlation was analyzed. RESULTS: Thirty-six patients were recruited. Mean age was 63.4 ± 13.0 (ranging from 23 to 87) years old. OSSN was predominant in men (21/36). Clinical appearances included papilliform in 17 eyes, gelatinous in 11 eyes, leukoplakic in 3 eyes, and 5 eyes in corneal intraepithelial neoplasia (CIN). Of 31 conjunctival OSSN, there were 4 in CIN I, 11 in CIN II, 13 in CIN III, and 3 in squamous cell carcinoma. Superior location was associated with higher-grade OSSN. Although statistical analysis was not significant, papilliform and multifocal lesions showed a trend of high-grade OSSN. The stages of tumor were 4, 5, 26, and 1 eye(s) in T1 to T4, respectively. Recurrence of disease occurred in 9 cases (25%) with mean recurrence time of 20.6 (range: 4 to 65) months. Multifocal lesion has a higher tendency for recurrence. CONCLUSION: Superior location was associated with high-grade OSSN, and papilliform OSSN might have a tendency of severe and invasive lesions. Multifocal lesions might be associated with higher-grade OSSN and higher recurrence rates.

Clinical outcomes of primary intraocular lymphoma patients treated with front-line systemic high-dose methotrexate and intravitreal methotrexate injection.

A standard treatment for patients with primary intraocular lymphoma (PIOL) remains unclear. This study retrospectively analyzed the clinical features and outcomes of 19 patients with PIOL who were treated with a first-line therapy comprising combined intravenous high-dose methotrexate and intravitreal methotrexate between January 2003 and December 2013. Thirteen (68.4 %) patients were female, and the median age at diagnosis was 57 (39-77 years). Diagnoses were based on the identification of abnormal lymphoid cells in vitreous fluid. Ten (52.6 %) patients had bilateral eye involvement, and six had concurrent central nervous system (CNS) involvement. All 19 patients achieved complete remission (CR) as confirmed by cytological examination of vitreous and cerebrospinal fluid and brain imaging if CNS was involved. Patients with concurrent brain involvement required a longer time to achieve CR. However, the duration of complete remission did not differ between patients with and without CNS involvement. The 5-year overall survival rate was 55.8 % for the total cohort and was higher (68.8 %) in patients with isolated PIOL than in those with concurrent CNS involvement. In all patients, methotrexate treatment was well tolerated, with manageable side effects. We conclude that combined intravitreal methotrexate and systemic high-dose methotrexate treatment is effective in patients with PIOL.

Combined Tractional and Rhegmatogenous Retinal Detachment in Proliferative Diabetic Retinopathy in the Anti-VEGF Era.

Purpose. To investigate the clinical features, surgical outcomes, and prognostic factors of combined rhegmatogenous and tractional detachment (combined RD) in proliferative diabetic retinopathy (PDR) in recent years. Methods. Medical records of PDR and combined RD treated with vitrectomy from 2008 to 2013 were retrospectively reviewed. Results. A total of 57 eyes from 49 patients were included. Nine eyes had received panretinal photocoagulation (PRP) and 7 eyes had intravitreal bevacizumab (IVB) within 3 months before RD developed. Thirty-eight eyes (66.7%) had ≧3 sites of broad adhesion of fibrovascular proliferation (FVP). Thirty-three eyes (57.9%) showed active FVP. Thirty-four eyes (59.6%) had extent of RD involving 3 or 4 quadrants. The primary reattachment rate was 93.0%, and the final visual acuity (VA) improved by more than 3 lines in 80.7% of eyes. Neovascular glaucoma occurred in 4 eyes postoperatively. Poor preoperative VA, severe vitreoretinal adhesion, and broad extent of RD had significant correlation with poor visual outcomes. Conclusion. PRP or IVB might play a role in provoking combined RD. The anatomical and functional success rates of surgery were high. Poor preoperative VA and severe proliferations predicted poor visual outcomes.
