Re: Schlenker et  al.: Efficacy, safety, and risk factors for failure of standalone ab interno gelatin microstent implantation versus standalone trabeculectomy. (Ophthalmology. 2017;124:1579-1588)
We read with interest the paper by Schlenker et  al.1 The authors state that the results with the Xen implant (Allergan, Parsippany-Troy Hills, NJ) with mitomycin C (MMC) are very similar to those of trabeculectomy with MMC in terms of both safety and efficacy. Based on these data, they suggest that the Xen implant is a reasonable alternative to trabeculectomy. When comparing the 2 groups in this paper, this finding does indeed seem to be the case. However, we think it is reasonable to point out that results from the trabeculectomy group are considerably worse than those from other real-world studies. (Source: Ophthalmology)

Establishing a Vision and Eye Health Surveillance System for the Nation: A Status Update on the Vision and Eye Health Surveillance System
Vision loss and eye disorders cost the US health care system $65.1 billion in 2013, the fifth leading cause of medical expenditures.1 Americans fear losing vision as much as or more than memory, hearing, or speech, and consider blindness among the top 4 worst things that could happen to them.2 It is estimated that as much as 98% of visual impairment and blindness, much of it consisting of uncorrected refractive error and untreated cataracts, in the United States can be prevented through timely diagnosis and early treatment.

We thank Dr Kirwan for his interest and comments on our article. Dr Kirwan asserts that an ab interno gelatin microstent is a reasonable alternative to trabeculectomy “where the trabeculectomy results are suboptimal.” In our earlier correspondence, we have shown that our trabeculectomy results are very much in keeping with the modern trabeculectomy literature, and elaborated on the “difficulties” Dr Kirwan alludes to but does not address in comparing resu lts across studies. For instance, the retrospective 2015 study by Kirwan et al compared with this one has differences in baseline characteristics (e.g., 3% vs. (...

Re: Francis et  al.: Clinical and morphologic characteristics of MEK inhibitor-associated retinopathy: differences from central serous chorioretinopathy (Ophthalmology. 2017;124:1788-1798)
We read with interest the work by Francis et  al,1 describing the clinical characteristics and OCT findings of a novel pathologic condition named mitogen-activated protein kinase (MEK) inhibitor-associated retinopathy (MEKAR). They explained that the toxicity profile of a novel class of chemotherapeutics that specifically blocks the mitogen-a ctivated protein kinase pathway includes the acute accumulation (within approximately 2 weeks from the first intake) of focal or multifocal, self-limited (approximately 32 days), nongravitational, subretinal fluid (SRF) pockets, distributed through the entire macula in one or both ey...

Thank you for the opportunity to respond to the critiques of Afshar et  al. We also thank Afshar et al for their interest in our manuscript. In their letter, the authors are critical of several aspects of our retrospective case series as well as our actual technique of vitrectomy and transvitrector port needle biopsy of choroidal melanoma.

The authors thank Velez-Montoya et  al for their comments on our publication.1 We are humbly grateful for their compliments on our study, which provides a morphologic description of mitogen-activated protein kinase (MEK) inhibitor-associated retinopathy (MEKAR) and discusses the features that make it distinct from central serous cho rioretinopathy (CSC). We are delighted the authors concur with our findings, description, and interpretation. We agree the inferior tracking of fluid and retinal pigment epithelial changes are more common in chronic CSC and, therefore, that its absence in MEKAR may be more reflective of the sh...

Oculodermal Melanocytosis, Darker Complexion, Choroidal Melanoma: A Missed Clue
A 68-year-old African-American woman with known history of an abnormally pigmented right optic nerve head was referred for a choroidal mass. Examination of the right eye demonstrated numerous pigmented scleral patches, diffuse iris thickening with mammillations, a hyperpigmented optic disc with slightly asymmetric hyperpigmentation of the choroid compared with her left eye (Fig 1A-B), and a choroidal melanoma (Fig 1C). External examination with bright illumination revealed subtly increased skin pigmentation of the right hemiface (Fig 1D). (Source: Ophthalmology)

Re: De Moraes et  al.: 24-2 Visual fields miss central defects shown on 10-2 tests in glaucoma suspects, ocular hypertensives, and early glaucoma (Ophthalmology. 2017;124:1449-1456)
We read with great interest the cross-sectional prospective study by De Moraes et  al1 describing the prevalence of visual field (VF) defects in glaucomatous eyes, glaucoma suspects, and ocular hypertensives with 24-2 and 10-2 VFs. Although the findings seemed to be very promising and could potentially change our VF testing strategy for glaucoma patients, a closer look leaves a number of unanswered questions and areas of concern that may be beneficial to explain to readers of the article.

Clinicopathologic Correlation of Choroidal Invasion in Retinoblastoma
Although choroidal invasion in retinoblastoma eyes is commonly observed pathologically, it has rarely been identified ophthalmoscopically or with ultrasound. Over a 2-year period, a 6-year-old girl was treated for bilateral retinoblastoma with systemic chemotherapy, intrarterial chemotherapy, laser, cryotherapy, and brachytherapy. She developed a dome-shaped brown/orange fundus lesion that was speckled on its surface with overlying serous retinal detachment (Fig 1A). Ultrasound confirmed that this emanated from the choroid but did not connect to the ciliary body (Fig 1B). (Source: Ophthalmology)

Bilateral Asymptomatic Cryptococcal Retinitis without Choroiditis or Vitritis
A visually asymptomatic 36-year-old man with HIV/AIDS (CD4: 4) was diagnosed with Cryptococcus gattii meningitis. He received 1 month of intravenous amphotericin and flucytosine followed by oral fluconazole with significant clinical improvement. Multifocal elevated circular retinal lesions without choroiditis or vitritis were evident bilaterally (Fig 1). OCT demonstrated preserved retinal architecture beyond the domed lesions with intraretinal speckled reflection. The fovea was spared bilaterally, consistent with uncorrected 20/20 vision.

We thank the authors for their interest in our work and the relevant points brought up for discussion. With regard to the sequence of visual field testing, in the African Descent and Glaucoma Evaluation Study (ADAGES) visual field testing order (24-2 vs 10-2) was assigned randomly at the patient level. The median time between visual field examinations was 20 minutes (25th to 75th quartile range, 16 –28). As the authors suggested, it is therefore, possible participants were fatigued by the time they performed the second test, whether it was a 24-2 or 10-2 examination. (Source: Ophthalmology)

Iris-Fixated Phakic Intraocular Lenses: New Results
Phakic intraocular lens (pIOL) implantation to correct refractive error is considered most often as an alternative to laser corneal refractive surgery in the setting of relatively high refractive error when there is an opportunity to retain the patient's ability to accommodate. There are 3 main designs: angle-supported anterior chamber, iris-claw anterior chamber, and posterior chamber, with several models commercially available. Because each pIOL offers different features, clinicians must match the pIOL specification carefully against their patients' needs and desired visual outcomes. (Source: Ophthalmology)
