ABSTRACT
PURPOSE: To report a case of bilateral marginal corneal infiltration upon treatment with trastuzumab, pertuzumab, and docetaxel via novel proposed mechanisms. CASE DESCRIPTION: A patient, diagnosed with metastatic breast cancer and positive for human epidermal growth factor receptor 2 (HER2) with high Ki67, presented with bilateral severe marginal corneal infiltration upon undergoing first cycle of triple chemotherapy: trastuzumab, pertuzumab, and docetaxel. Treatment with topical corticosteroids and antibiotics was unsuccessful and was replaced by allogeneic serum eye drops (SED). The case improved significantly 10 days upon starting allogeneic SED. CONCLUSIONS: We propose that trastuzumab, pertuzumab, and docetaxel suppress HER2 and Ki67 in the cornea and lacrimal gland. To the best of our knowledge, our report is the first to highlight the potential impact of this triple chemotherapy on the lacrimal gland and cornea and the first to highlight the proposed role of Ki67 suppression in damaging corneal integrity.

INTRODUCTION: To explore the potential link between macular atrophy (MA) of the retinal pigment epithelium (RPE) in patients with neovascular age-related macular degeneration (nAMD) and anti-vascular endothelial growth factor (anti-VEGF) treatment. METHODS: Through a balanced overview of the field from a largely clinical perspective, we looked at available evidence on the topic of MA correlation with anti-VEGF therapy and examined possible risk factors for MA development in the context of nAMD treatment with anti-VEGF. RESULTS: Links have been reported to connect both MA incidence and progression to treatment frequency and to the anti-VEGF drug type. CONCLUSIONS: All reports agree on the fact that de novo development of MA in anti-VEGF-treated eyes is frequent and multifactorial. Research data shows an expansion of atrophy during anti-VEGF treatment. There are mixed conclusions about the correlation of MA incidence or progression with treatment-related risk factors. It mostly appears that there is no straightforward link. More clinical research is still needed to further understand this association.
ABSTRACT
INTRODUCTION: The purpose of this review was to explore the potential link between macular atrophy (MA) of the retinal pigment epithelium in patients with neovascular age-related macular degeneration (nAMD) with the disease characteristics and morphological features. METHODS: To this end, we performed a search of peer-reviewed articles published on the PubMed database and included all relevant papers. We then examined these papers for possible risk factors for MA development in the context of nAMD treated with anti-vascular endothelial growth factor drugs, as well as possible protective factors. RESULTS: Our review of the relevant publications revealed that areas of MA can be directly visualized through multiple imaging modalities. Associations have been identified between MA of the retinal pigment epithelium and choroidal neovascular membrane characteristics, intra- and subretinal fluid, pigment epithelial detachment, choroidal thickness, subretinal hyperreflective material, outer retinal tubulations, hemorrhage, subretinal drusenoid deposits, refractile drusen, hyperreflective foci, retinal angiomatous proliferation, polypoidal choroidal vasculopathy, geographic atrophy in the fellow eye, genetic factors, and age. CONCLUSION: The findings of this review indicate that a multimodal approach is recommended for the assessment of MA. The conclusions drawn to date on the correlation between MA development or progression of MA and specific risk factors and possible protective factors are mixed. More clinical research is needed to reach a better understanding of this association.
ABSTRACT
PURPOSE: To assess whether best-corrected visual acuity and pigment epithelial detachment (PED) height, volume, and reflectivity in patients with wet age-related macular degeneration are influenced by baseline anatomical and functional parameters, including quantifiable metrics of PED morphology and choice of treatment. METHODS: One hundred two consecutive, treatment-naive wet age-related macular degeneration patients with PED (>50 µm) treated with aflibercept (52) or ranibizumab (50) were retrospectively included. Pigment epithelial detachment height, horizontal and vertical dimensions, and volume were recorded at baseline, 3 months, and 1 year, respectively. Bespoke image analysis software provided a quantifiable measure of reflectivity. RESULTS: Best-corrected visual acuity at 3 months was influenced by baseline best-corrected visual acuity (P = 0.006). Pigment epithelial detachment height was influenced by baseline height (P = 0.009), subretinal fluid (P = 0.008), central macular thickness (P = 0.006), and use of aflibercept (P = 0.003) at 3 months and by baseline height (P = 0.018), volume (P = 0.017), vertical dimension (P = 0.0004), and aflibercept (P = 0.015) at 1 year. Pigment epithelial detachment reflectivity increased from 43.59 to 55.86 (3 months) and 57.35 (1 year) (P < 0.001) and was influenced by its baseline values and, interestingly, use of aflibercept at 3 months (P = 0.013). CONCLUSION: Quantifiable metrics of PED morphology improve with treatment, and PED content becomes hyperreflective, more so on aflibercept. Pigment epithelial detachments respond better in the context of more active disease. More hyporeflective PED content may predispose to better treatment response, especially with aflibercept.

PURPOSE: Wet age-related macular degeneration (ARMD) is a leading cause of visual impairment. Anti-vascular endothelial growth factor (VEGF) injections are the mainstay of treatment but require monthly injections and frequent hospital visits. A novel approach to treatment with the use of stereotactic radiotherapy (Oraya IRay) as an adjunct to ranibizumab injections has shown promising results. We explored patients' experiences of receiving Oraya therapy for wet ARMD. METHODS: We present a consecutive case series with objective and detailed reporting of the personal experiences of 5 patients with active wet ARMD treated with Oraya radiotherapy in our unit. We provided all patients who had received one Oraya treatment with a standardized survey composed of 10 questions addressing the experience of receiving this treatment. RESULTS: Generally, patients reported positive experiences of receiving Oraya treatment and perceived this treatment as a better option in comparison with anti-VEGF injections. However, the patients' perceptions of Oraya treatment varied according to patients' previous experiences of anti-VEGF injections and expectations of treatment. CONCLUSIONS: Patients mainly justified their decision to receive Oraya treatment by expecting fewer intravitreal injections, but more research on this topic is needed to suggest new evidence-based treatment protocols for patients with wet ARMD.
