This issue of JAMA Ophthalmology contains 2 articles1,2 that emphasize the occurrence of a predominant ocular phenotype in adult patients with 2 forms of neuronal ceroid lipofuscinosis (NCL), which is classically recognized as a group of severe neurodegenerative disorders of childhood. Smirnov et al1 demonstrate the presence of a phenotype-genotype correlation in 15 adult patients with biallelic pathogenic variants in CLN3 drawn from a cohort of 1533 patients and described as having nonsyndromic inherited retinal disease. The authors1 divide them into 2 groups: 6 patients with mild rod-cone degeneration of middle-aged onset and legal blindness in their 70s and 9 patients with a severe retinal degeneration involving early macular atrophic changes and legal blindness by their 40s. While none of the patients reportedly had any neurological symptoms, the details of their neurological workups and specific questions about mental functions that are generally affected in NCL are lacking. No investigations of cardiac function or the spine, both recently recognized as affected organs in NCL type 3,3 were conducted. Also, the authors did not compare retinal findings among siblings in the 4 sibships in this report.1 If the clinical course of the disease is consistent within pedigrees, this will give even more credence to their demonstration that the CLN3 pathogenic variants in these 2 groups of patients are associated with phenotypes that are milder than those of patients with classic juvenile NCL. Patients with classic juvenile NCL or Batten disease present with rapidly progressive loss of visual acuity followed by neurological deterioration in the first decade of life and demise as young adults.4 Of the patients with this phenotype, 73% are homozygous for a common homozygous deletion variation of 966 basepairs involving exons 7 and 8 of CLN3, as opposed to the mostly missense CLN3 variations in the 15 patients1 with a predominant retinal phenotype.5 Furthermore, the gene sequence variants in the milder cases were distinct from those in the more severe cases, indicating an even more refined genotype-phenotype correlation.

although reports on coronavirus disease 2019 (COVID-19) affecting health already exceed 32?000 articles, studies on direct effects on the eye appear to be limited.1 Conjunctivitis, retinitis, episcleritis, and optic neuritis have all been described as ocular manifestations, but frequency and morbidity are fortunately not striking. This has relieved us as ophthalmologists and given the impression that we have been spared a heavy patient load attributable to COVID-19 complications. We have focused on reorganizing our clinics and made sure that anti–vascular endothelial growth factor treatments and other urgent patient care were not obstructed.

In this issue of JAMA Ophthalmology, Blitzer and coauthors1 present findings from a large national database of health insurance claims that are suggestive of an association of metformin with protection against age-related macular degeneration (AMD). Given the burden of vision impairment secondary to advanced AMD, the lack of proven therapies for atrophic AMD, and the burden of treatment associated with neovascular AMD, interventions aimed at preventing AMD are urgently needed. As such, the findings reported1 are of great interest. While the authors hypothesize about the role of metformin as a potential intervention for AMD, the results need to be cautiously interpreted in line with the limitations that are at play when conducting case-control studies with administrative data, as acknowledged by the authors.1

In his interview at the 2020 American Academy of Ophthalmology Annual Meeting, the influential author Malcolm Gladwell recounted the many ways in which the coronavirus disease 2019 pandemic has held an unflattering mirror up to the deep inequities that exist in our society. He challenged medical professionals to do more to help underserved communities—not just by volunteering their individual services but to actively find creative solutions to address major health disparities and to improve patient outcomes on a larger scale.

Monogenic inherited retinal degeneration (IRD) occurs from variations in genes associated with critical biochemical or physiological pathways necessary for normal function of outer retinal cells, which, when deficient, create disease with substantial visual loss in patients. Gene replacement (or augmentation) therapy involves transporting a good copy of the defective gene along with a promoter to the affected cells of the retina, most often requiring vitreoretinal surgery and subretinal injection. The ideal gene for augmentation is one with a function that is either enzymatic or involves a single biochemical pathway, although the gene and promoter must also be small enough to fit within the 4.7-kilobase carriage capacity of an adeno-associated virus (AAV), which is the vector used for most currently active gene augmentation clinical trials. The AAV platform was first reported to be successful for IRD gene augmentation therapy when the US Food and Drug Administration approved Luxturna for the treatment of retinitis pigmentosa or Leber congenital amaurosis associated with biallelic variations in the retinoid isomerohydrolas gene, RPE65 (OMIM 180069), in 2017.1 Other IRDs currently undergoing gene augmentation clinical trials using AAV include the achromatopsia genes (cyclic nucleotide-gated channel, alpha-3 [CNGA3; OMIM 600053] and cyclic nucleotide-gated channel, beta-3 [CNGB3; OMIM 605080]), the choroideremia gene (CHM; OMIM 300390), the X-linked retinitis pigmentosa gene (retinitis pigmentosa GTPase regulator [RPGR; OMIM 312610]), the X-linked retinoschisis gene (retinoschisin [RS1; OMIM 300839]), and retinitis pigmentosa associated with the phosphodiesterase 6B, cGMP-specific, rod, beta gene, PDE6B (OMIM 180072). However, there are many other larger IRD genes that exceed the carriage capacity of AAV. The equine infectious anemia virus has a higher carriage capacity and has been developed for clinical trials of gene augmentation therapy for Usher syndrome, type 1B (myosin 7A [MYO7A; OMIM 276903]) and Stargardt disease (ATP-binding cassette, subfamily A, member 4 [ABCA4; OMIM 601691]); however, both early-phase clinical trials are currently closed to enrollment because of administrative changes. Thus, the equine infectious anemia virus platform remains an unproven strategy. Other promising AAV-based augmentation strategies adapted for large IRD genes that are currently in preclinical development include the dual-vector and minigene approaches.2,3

In 1971, Goldberg1 published the eponymous sickle cell retinopathy staging system, which was based on astute clinical observations along with an observed sequential pattern of vascular remodeling in the peripheral retinas of patients with sickle cell disease (SCD). This description of sea fan neovascularization in proliferative sickle retinopathy has arguably produced one of the most recognizable systemic disease associations in the field of ophthalmology and certainly in the retina. What is not as widely cited is the early recognition of the macular vascular changes in patients with SCD in the study by Goldberg and colleagues.2 In 1974, these authors described pathologic avascular zones in the areas temporal to the fovea, changes in normal foveal architecture, and abnormalities in the macular microvasculature in patients, deemed sickling maculopathy.

The article by Steren et al1 provides an excellent review of the accuracy of current applications (apps) for presenting high-contrast (black letters, white background) visual acuity (VA) tests on Apple devices, such as iPhones and iPads. The authors appropriately limited their evaluation to apps that provide free access to potential patients as well as specification of viewing distance to optimize accessibility and ensure appropriate character size. The authors note that a prior evaluation of VA apps in 20152 revealed numerous errors in calibration, such as appropriate letter size for specified viewing distances. Given the plethora of new apps and increasing need for telemedicine during the coronavirus disease 2019 (COVID-19) pandemic, the authors astutely sought to update and refine this analysis applicable to ophthalmology, optometry, and multiple health care sectors. Their results further substantiate the inaccuracy of current VA apps for Apple devices, which likely occur in other devices as well.

the ongoing coronavirus disease 2019 (COVID-19) pandemic has produced widespread changes to our day-to-day lives in 2020. Many of us have spent the year working or going to school from home. Other interventions have been implemented to keep us and others safe when we do venture from home, including the wearing of face masks. Additionally, widespread availability of alcohol-based hand sanitizer, often in automatic, hands-free dispensers, has become commonplace in public places.

To the Editor I congratulate Shah and colleagues1 on their important contributions regarding the association between pentosan and maculopathy. I am concerned, however, that the authors have overreached in their conclusions with potentially enormous and likely unintended consequences. The authors’ statement that maculopathy progresses after drug cessation is important. The authors stated that “maculopathy continues to evolve after drug cessation for at least 10 years.”1 Eleven patients are described, and all but 2 stopped drug use at baseline or shortly before. There was only 1 patient with a 10-year gap between cessation and examination. No images are provided for this patient but the text reports that the activity was bilateral cystoid macular edema (CME). This is puzzling since no other patient had this finding and it is not clear that this development is in any way related to prior drug exposure. There are dozens if not hundreds of possible causes for CME and, in some cases, a cause may never be found. Given the patient’s reported response to oral acetazolamide, and in the absence of CME in any other patients, I find it highly speculative to link this development to the use of pentosan 10 years after exposure. Of the patients monitored prospectively after drug cessation, most were monitored for 1 year or less. None developed CME. There were 2 patients who were monitored for more than 3 years, and both were reported to have stable symptoms throughout this follow-up.

In Reply We thank Vander for his insightful comments on our study of pentosan polysulfate (PPS) maculopathy.1 We agree with the general sentiment, particularly with the statements regarding the seriousness of this public health issue and the importance of being careful in drawing conclusions from the data. As Vander suggested, our report on disease course after drug cessation has clinical and medicolegal ramifications. More importantly, affected patients eagerly await information about long-term visual prognosis, and we wish to provide them with accurate information.

To the Editor This letter is in reference to the article by Ayto?an et al.1 It was an interesting and relevant article. The objective of the article was to investigate the presence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) on the environmental surfaces of an ophthalmology examination room after visits by patients who were asymptomatic and had passed coronavirus disease 2019 (COVID-19) triage. However, the authors did not mention whether the patients, their companions, or the health care workers were wearing masks when the examinations were being performed. The study is expected to have completely different results if the participants were with or without masks and hence this point needs to be clearly mentioned in the study design. The type of masks worn by patients, companions, and health care workers, if known, should also be specified, or if it is not known, then that needs to be stated.

In Reply We thank the authors for their letter regarding our article, “Detection of Coronavirus Disease 2019 Viral Material on Environmental Surfaces of an Ophthalmology Examination Room.”1 We are grateful for the opportunity to discuss the topic of masks, which we did not mention in the original article because of the word count limitation of the journal’s instructions. We agree with the authors that whether the patients, companions, and health care workers were wearing masks could alter the outcomes and interpretation of the study. All patients and companions were wearing different kinds of masks, including surgical masks and simple homemade cloth masks. Health care workers were wearing Filtering Facepiece 2 masks during the study. However, there was no standardized particle-filtering mask use in the study. Furthermore, we did not record the mask types. We agree that this was a limitation of the study. We would like to highlight that this study was not interventional but only observational, so standardization of mask use did not occur.
