Purpose: To identify the visual acuity outcomes of patients with age-related macular degeneration treated with intravitreal anti–vascular endothelial growth factor injections over a 10-year period. Methods: This was a retrospective, cohort study of eyes with exudative age-related macular degeneration that received ≥2 intravitreal anti–vascular endothelial growth factor injections and had at least 10 years of follow-up after the initiation of treatment. Snellen visual acuity was recorded at baseline and then annually until the last year of follow-up. Optical coherence tomography data were collected at the time of treatment initiation and at the last examination visit. A subanalysis was performed on patients who continued to receive anti–vascular endothelial growth factor therapy using a modified treat and extend protocol versus those who discontinued treatment for longer than 1 year. Results: One hundred thirty eyes of 115 patients met the inclusion criteria. The mean follow-up after treatment initiation was 11.1 ± 0.7 years. Eyes received an average of 45.1 ± 32.3 intravitreal injections in total and a mean of 5 to 7 injections per year. The baseline mean logMAR visual acuity was 0.61 ± 0.5 (Snellen acuity 20/81), and the final mean logMAR visual acuity was 0.88 ± 0.7 (20/152, P value = <0.0001). There were 40 eyes that received at least one injection every year. These eyes did not have a significant change in visual acuity between the baseline and final examinations 0.47 ± 0.4 (20/59 vs. 0.58 ± 0.5 [20/76, P = 0.28]), whereas the eyes that did not receive at least one injection every year saw a significant decline in visual acuity 0.67 ± 0.5 (20/94 vs. 1.01 ± 0.7 [20/205, P < 0.0001]). Conclusion: Eyes with exudative age-related macular degeneration that received intravitreal injections every year had stable visual acuity over a 10-year period. Continuous intravitreal anti–vascular endothelial growth factor therapy may stabilize visual acuity for 10 years and potentially longer.

Purpose: The purpose of this article is to provide a data-driven set of best practices to consider in the management of diabetic macular edema (DME). Methods: The current discussion and recommendations represent the authors’ interpretations of data from selected references based on perceived relevance and study design. Results: DME is a common cause of visual impairment globally. The underlying progressive retinal microvascular damage is associated with upregulation of VEGF and a multitude of other inflammatory pathways. Three clinically relevant subcategories of DME can be identified: central-involved DME (CIDME) with preserved visual acuity, CIDME with associated visual loss, and non-CIDME. Management approaches may include observation, laser photocoagulation, intravitreal pharmacotherapy with anti-VEGF agents or corticosteroids, or a combination of these, and may vary depending on the specific type of DME and associated severity of diabetic retinopathy. Additional factors to consider in the management of patients with DME include the appropriate use of imaging and recognition of the chronic nature of the underlying disease process in many eyes. Conclusions: DME management is complex. Intravitreal pharmacotherapies are the current cornerstone of treatment for CIDME and appear poised to remain so for the foreseeable future.

Purpose: The relationship between age-related macular degeneration (AMD) and malignancy, especially cutaneous malignancies, is not well studied. We investigated a possible association between AMD and cutaneous malignancies. Methods: A retrospective, consecutive review of all patients who had received at least 1 intravitreal injection for wet AMD between January 1, 2004, and December 31, 2013, was conducted using the Rochester Epidemiology Project in Olmsted County, Minnesota. Age- and sex-matched control groups included 473 pre–anti–vascular endothelial growth factor era wet AMD patients, 504 concurrent time dry AMD patients, and 504 patients with no AMD. The rates of AMD and overall malignancy, cutaneous malignancies, and specific types of cutaneous malignancies were compared between groups of patients. Results: Patients with wet AMD incurred an increased rate of overall malignancies compared to patients with dry AMD {52.8% wet AMD (confidence interval [CI]: 48.3–57.2) vs. 43.7% dry AMD (CI: 39.3–48.1); P= 0.003} or those without AMD (52.8% wet AMD [CI: 48.3–57.2] vs. 35.3% no AMD [CI: 31.1–39.7]; P = <0.001). Patients with dry AMD also had higher rates of malignancy than those without AMD (43.7% dry AMD [CI: 39.3–48.1] vs. 35.3% no AMD [CI: 31.1–39.7]; P = 0.007). Rate of cutaneous malignancies was increased in patients with wet AMD compared to patients with dry AMD (24.4% wet AMD [CI: 20.7–28.4] vs. 14.6% dry AMD [CI: 11.5–17.9]; P = <0.001) and those with no AMD (24.4% wet AMD [CI: 20.7–28.4] vs. 9.7% no AMD [CI: 7.3–12.7]; P = <0.001). Conclusion and Relevance: To the best of our knowledge, this is the first report to establish an association between AMD and cutaneous malignancies, supporting a possible discussion of the association when a patient presents with one of the two conditions.

Purpose: To report a case of adult-onset vitelliform macular dystrophy in a patient who was found to have a previously unreported variant of the IMPG2 gene. Methods: Case report. Results: A 65-year-old white woman with no significant medical or ocular history presented with a complaint of persistent wavy vision for 10 months. On funduscopic examination, bilateral vitelliform lesions of approximately 1 mm in the right eye and 0.5 mm in the left eye were evident, with no choroidal neovascularization in either eye. The patient was diagnosed with adult-onset vitelliform macular dystrophy. Genetic testing revealed a single likely pathogenic variant of the IMPG2 gene that may explain the examination findings. Conclusion: Adult-onset vitelliform macular dystrophy is a common and relatively benign condition occurring in approximately 1 in 8,000 individuals. Although vitelliform lesions can be a manifestation of systemic diseases or be idiopathic, in a minority of patients, genetic predisposition may play a role. Mutations in four particular genes BEST1, PRPH2, IMPG1, and IMPG2 have been associated with some cases of adult-onset vitelliform macular dystrophy, with this particular gene variant of IMPG2 being previously unreported.
