RESUMEN
PURPOSE: To describe how a vertical lid split helps excision and reconstruction of conjunctival tumors. METHODS: All patients with a limited view of conjunctival tumors involving the fornices underwent a vertical lid split procedure to improve access during resection and reconstruction. RESULTS: There were 11 cases where vertical lid splits were performed to assist excision and reconstruction of conjunctival tumors on patients between 2015 and 2019. There were 4 male and 7 female patients, 50-85 years of age, mean age 67.2 years. Four patients had invasive malignant melanoma, 2 melanoma in situ, 3 invasive squamous cell carcinoma, and 2 squamous cell carcinoma in situ. The authors have had no local reoccurrences in 9 patients (follow-up 8-54 months, mean 18 months). One patient's deep margins were involved and proceeded to exenteration, and 1 patient died from liver metastases. CONCLUSIONS: A vertical lid split incision of either or both eyelids, well away from the visible tumor edge splays the lid open allowing the whole conjunctival surface to be stretched out and viewed as a single flat sheet. This aids excision and reconstruction of the tumor, potentially reducing the risk of seeding and simplifying the reconstruction.

AIM: To compare visual acuity and central macular thickness (CMT) changes in neovascular age related macular degeneration patients treated with either 6 weekly bevacizumab regimen or 4 weekly ranibizumab on an as required basis. METHODS: Patients made an informed choice between bevacizumab 1.25 mg or ranibizumab 0.5 mg. The selected treatment was administered in the first 3 visits. Bevacizumab patients were followed-up 6 weekly and ranibizumab 4 weekly. Retreatment criteria was based on the reduction of >5 letters in the best-corrected visual acuity (BCVA), the presence of retinal fluid on optical coherence tomography (OCT) or new retinal haemorrhage. RESULTS: Visual acuity at 2y bevacizumab patients gained 7.0 letters and ranibizumab 9.2 (P=0.31, 95% CI -6.4 to 2.0). At 2y 86% of bevacizumab and 94% ranibizumab patients had not lost 15 letters or more (P=0.13). Mean CMT decreased at 2y bevacizumab by 146 µm, ranibizumab 160 µm (P=0.72). Mean number of injections was at 2y bevacizumzb 11.9, ranibizumab 10.3 (P=0.023). CONCLUSION: Bevacizumab 6 weekly on an as required basis was not demonstrably non-inferior to ranibizumab 4 weekly pro re nata (prn) in terms of BCVA and change in CMT. In the bevacizumab group, one more injection was required in the second year compared to the ranibizumab group.
RESUMEN
Cataract is the most common complication of vitrectomising surgery in the phakic eye. Progressive nuclear sclerosis (NS) causes a myopic shift. This change in refractive status can predispose to the development of monovision in presbyopic individuals. Recognition of adaptation to monovision is important when undertaking sequential cataract surgery. Our case describes a patient whose adaptation to monovision was only recognised after its reversal. Predisposing factors are discussed and lessons highlighted.
