RESUMEN
A 37-year-old woman was referred for evaluation of a retinal detachment in her left eye. Posterior examination results demonstrated a retinal detachment in the posterior pole with shifting fluid and no identifiable retinal break, and there was a thickened choroid with a hyporeflective band on ultrasound biomicroscopy. What would you do next?

BACKGROUND AND OBJECTIVE: We investigated the reliability of near-infrared reflectance (NIR) imaging as a method of assessing severity of diabetic retinopathy (DR). PATIENTS AND METHODS: One hundred ninety-five NIR images were reviewed by two graders for the number of hyporeflective foci, presence or absence of vascular abnormalities, and presumptive DR stage; these were correlated to fundus photography-defined DR stage. Interrater reliability was confirmed via one-way random effects model of intraclass correlation coefficients. Analysis of variance was used in subgroup analysis, receiver operating characteristic (ROC) curves were created to validate reliability of the model, and logistic regression was used to model foci and vascular abnormalities as predictors for moderate or worse disease. RESULTS: A statistically significant difference in mean number of hyporeflective foci was found between no DR and moderate non-proliferative DR (NPDR; P < 0.0001), no DR and severe NPDR (P < 0.001), no DR and proliferative DR (PDR; P < 0.0001), mild and moderate NPDR (P = 0.008), mild and severe NPDR (P < 0.001), and mild NPDR and PDR (P < 0.001). The area under the ROC curve was 0.849 (CI: 0.792 to 0.905). The threshold for detection of moderate NPDR or worse was 4.75 foci, with a sensitivity of 79.0% and a false positive rate of 20.0%. Multivariate logistic regression model incorporating hyporeflective foci with vascular abnormalities (odds ratio [OR] = 1.592, 95% CI: 1.381 to 1.835; P < 0.001) was able to accurately predict moderate disease or worse, just moderate disease (OR = 1.045, 95% CI: 1.003 to 1.089; P = 0.035), severe disease (OR = 1.050, 95% CI: 1.006 to 1.096; P = 0.027), and proliferative disease (OR = 1.050, 95% CI: 1.008 to 1.095; P = 0.018). CONCLUSIONS: NIR imaging may be an adjunct tool in screening for DR. [Ophthalmic Surg Lasers Imaging Retina 2024;55:318-325.].

Purpose: To study patient follow-up after they engage in a teleretinal screening program and to understand potential barriers to care. Methods: This was a retrospective analysis and a prospective study of telephone-based patient interviews of outpatients screened for diabetic retinopathy (DR) through a teleretinal referral system. Results: Of 2761 patients screened through a teleretinal referral program, 123 (4.5%) had moderate nonproliferative DR (NPDR), 83 (3.0%) had severe NPDR, and 31 (1.1%) had proliferative DR. Of the 114 patients with severe NPDR or worse, 67 (58.8%) saw an ophthalmologist within 3 months of referral. Eighty percent of interviewed patients reported they were not aware of the need for follow-up eye appointments. Conclusions: Of patients with severe retinopathy or worse, 58.8% presented for in-person evaluation and treatment within 3 months of screening. Although this result was negatively affected by factors related to the COVID-19 pandemic, key elements of patient education and improved referral strategies to facilitate in-person treatment are essential to improving follow-up after patients engage in telescreening.
RESUMEN
The advent of anti-vascular endothelial growth factor (VEGF) agents has revolutionized the treatment of retinal neovascular diseases including neovascular age-related macular degeneration (nAMD), a leading cause of irreversible blindness. Multiple agents and methods for drug delivery are emerging to increase the duration of treatment effect and treatment interval, reducing the overall treatment burden on patients and clinicians. The newest agent on the market is faricimab. This medication targets two distinct pathways in retinal angiogenesis, VEGF-A and Ang-2, to create a more durable effect. Phase 3 trials for this drug compared treatment intervals up to 16 weeks against aflibercept dosed at 8-week intervals for both nAMD and diabetic macular edema (DME). While the drug shows similar functional and anatomic outcomes with a low adverse effect profile and trial data demonstrating increased treatment duration, its exact place in the VEGF marketplace is yet to be determined. In this article, we discuss the mechanism of action, pivotal clinical trials leading to approval, and the anticipated role for faricimab in the treatment of retinal neovascular disease.

PURPOSE: To describe cases of unilateral cone-rod dysfunction presenting in two middle-aged females. METHODS: This case series highlights two middle-aged female patients with progressive visual decline in one eye. Fundus photography, fundus autofluorescence (FAF), spectral-domain optical coherence tomography (SD-OCT), multi-focal electroretinogram (mfERG), full-field electroretinogram(ffERG), and genetic testing were obtained. RESULTS: In the first patient, mfERG showed an extinguished response and ffERG demonstrated markedly reduced a-wave and b-wave amplitudes (more pronounced under photopic conditions) in the right eye. SD-OCT showed attenuation of the ellipsoid zone of the right eye. Similar findings were appreciated in the second patient. Genetic testing in the first patient identified three heterozygous variants in PRPH2, RCBTB1, and USH2A. The second patient was found to have heterozygous variants in BBS1 and ABCA4. CONCLUSION: These two cases add to the literature of case reports of unilateral cone-rod and rod-cone dystrophies. However, the underlying etiology of the unilateral pattern of cone-rod dysfunction and the significance of the heterozygous mutations found in both cases remains uncertain.

PURPOSE: To identify risk factors for the development of new-onset, postoperative diplopia following orbital decompression surgery based on patient demographics, clinical exam characteristics, radiographic parameters, and surgical techniques. METHODS: We conducted a multi-center retrospective chart review of patients who underwent orbital decompression for thyroid eye disease (TED). Patient demographics, including age, gender, smoking history, preoperative exophthalmometry, clinical activity score (CAS), use of peribulbar and/or systemic steroids, and type of orbital decompression were reviewed. Postoperative diplopia was determined at a minimum of 3 months postoperatively and before any further surgeries. Cross-sectional area ratios of each extraocular muscle to orbit and total fat to orbit were calculated from coronal imaging in a standard fashion. All measurements were carried out using PACS imaging software. Multivariable logistic regression modeling was performed using Stata 14.2 (StataCorp, College Station, TX). RESULTS: A total of 331 patients without preoperative diplopia were identified. At 3 months postoperatively, 249 patients had no diplopia whereas 82 patients developed diplopia. The average postoperative follow-up was 22 months (range 3-156) months. Significant preoperative clinical risk factors for postoperative diplopia included older age at surgery, proptosis, use of peribulbar or systemic steroids, elevated clinical activity score, and presence of preoperative compressive optic neuropathy. Imaging findings of enlarged cross-sectional areas of each rectus muscle to the overall orbital area also conferred a significant risk of postoperative diplopia. Regarding surgical factors, postoperative diplopia was more common among those undergoing medial wall decompression, bilateral orbital surgery, and balanced decompression, whereas endoscopic medial wall decompression was found to be relatively protective. CONCLUSIONS: This study identifies risk factors associated with the development of diplopia following orbital decompression using multivariable data. This study demonstrates that several characteristics including age, clinical activity score, the cross-sectional muscle to orbit ratios, in addition to the type of orbital decompression surgery, are predictive factors for the development of new-onset postoperative diplopia.

Purpose: To describe delayed detection of pericentral hydroxychloroquine (HCQ) toxicity. Methods: 67-year-old Dominican woman with rheumatoid arthritis on HCQ presented for examination. Results: Spectral-domain optical coherence tomography (SD-OCT) demonstrated bilateral cystoid macular edema with parafoveal attenuation of the external limiting membrane (ELM) and the ellipsoid zone (EZ). ELM and EZ disruption was present in inferior macula. While subtle superior defects were present on 10-2 visual fields, superior pericentral defects were noted on 24-2 testing. Hyperautofluorescence along inferior arcades corresponded to SD-OCT and visual fields. Examination 2 years prior demonstrated nonspecific points of depression on 10-2 visual fields and normal central SD-OCT findings. EZ and ELM disruption was present in the perifoveal inferior macula. Conclusions: Early pericentral distribution of HCQ toxicity is not limited to Asian patients. Detecting pericentral HCQ toxicity involves reviewing entire macular cube on OCT. When OCT changes are suspected on parafoveal OCT B-scans, visual field testing with 24-2 may be more sensitive than 10-2.
RESUMEN
Allergic fungal sinusitis (AFS) and eosinophilic mucin chronic rhinosinusitis (EMCRS) are subtypes of a chronic rhinosinusitis with eosinophilia that have different diagnostic criteria but are phenotypically similar. Ophthalmic complications may be the presenting symptoms. Treatment of ophthalmic complications is typically directed at reducing the inflammatory burden in the sinuses and rarely requires direct surgical intervention. However, atypical cases with associated subperiosteal abscess may necessitate orbital surgery. The authors present 2 cases of EMCRS with orbital involvement - one that responded to the traditional treatment of oral corticosteroids and functional endoscopic sinus surgery (FESS), and the other requiring surgical drainage of a subperiosteal abscess in order to describe the management strategies based on clinical presentation.
RESUMEN
Purpose: The purpose was to establish the position of the fovea centralis to the optic nerve via en-face, near-infrared spectral domain optical coherence tomography (NIR-OCT) in healthy patients. This may shed light on physiological variability and be used for studying subtle cases of foveal ectopia in macular pathology and after retinal detachment. Methods: SD-OCT data of 890 healthy eyes were retrospectively analyzed. Exclusion criteria included axial myopia causing tilting of the optic disc, peripapillary atrophy >1/3 the width of the disc, macular images excluding greater than half of the optic disc, and patients unable to maintain vertical head positioning. Two independent reviewers measured the horizontal and vertical distance from the fovea to the optic disc center and optic disc diameter via cross-sectional and en-face scanning laser ophthalmoloscopy OCT imaging. Results: 890 eyes were included in the study. The right and left eyes differed in the horizontal distance from the fovea to the disc center (4359 vs. 4248 µm, P < 0.001) and vertical distance from the fovea to the disc center (464 µm vs. 647, P < 0.001). This corresponded to a smaller angle between the right and left eyes (6.07° vs. 8.67°, P < 0.001). Older age was associated with a larger horizontal (P = 0.008) and vertical distance (0.025). These differences persisted after correcting for axial length in the 487 patients with axial-length data. Conclusions: This study compares the position of the fovea centralis among individuals without macular pathology on a micron level basis. The significant variability between right and left eyes indicates that contralateral eye evaluation cannot be reliably used. Rather, true foveal ectopia requires assessments of preoperative and postoperative NIR-OCT scans. This finding is relevant to retinal detachment cases and evaluation of subtle foveal ectopia. Translational Relevance: This finding is relevant to retinal detachment cases and evaluation of subtle foveal ectopia.

Importance: The American Academy of Ophthalmology (AAO) indicated that urgent or emergent vitreoretinal surgical procedures should continue during the coronavirus disease 2019 (COVID-19) pandemic. Although decreases in the frequency of critical procedures have been reported outside the field of ophthalmology, analyses are limited by volume, geography, and time. Objective: To evaluate whether the frequency of ophthalmic surgical procedures deemed urgent or emergent by the AAO changed across the United States during the COVID-19 pandemic. Design, Setting, and Participants: Vitreoretinal practices from 17 institutions throughout the US participated in this multicenter cross-sectional study. The frequency of 11 billed vitreoretinal Current Procedural Terminology (CPT) codes across respective weeks was obtained from each practice between January 1, 2019, and May 31, 2020. Data were clustered into intravitreal injections (code 67028), lasers and cryotherapy (codes 67141, 67145, and 67228), retinal detachment (RD) repairs (codes 67107, 67108, 67110, and 67113), and other vitrectomies (codes 67036, 67039, and 67040). Institutions were categorized by region (Northeast, Midwest, South, and West Coast), practice setting (academic [tax-exempt] or private [non-tax-exempt]), and date of respective statewide stay-at-home orders. Main Outcomes and Measures: Nationwide changes in the frequency of billing for urgent or emergent vitreoretinal surgical procedures during the COVID-19 pandemic. Results: A total of 526â¯536 CPT codes were ascertained: 483â¯313 injections, 19â¯257 lasers or cryotherapy, 14â¯949 RD repairs, and 9017 other vitrectomies. Relative to 2019, a weekly institutional decrease in injections was observed from March 30 to May 2, 2020, with a maximal 38.6% decrease (from a mean [SD] of 437.8 [436.3] to 273.8 [269.0] injections) from April 6 to 12, 2020 (95% CI, -259 to -69 injections; P = .002). A weekly decrease was also identified that spanned a longer interval, at least until study conclusion (March 16 to May 31, 2020), for lasers and cryotherapy, with a maximal 79.6% decrease (from a mean [SD] of 6.6 [7.7] to 1.5 [2.0] procedures) from April 6 to 12, 2020 (95% CI, -6.8 to -3.3 procedures; P < .001), for RD repairs, with a maximal 59.4% decrease (from a mean [SD] of 3.5 [4.0] to 1.6 [2.2] repairs) from April 13 to 19, 2020 (95% CI, -2.7 to -1.4 repairs; P < .001), and for other vitrectomies, with a maximal 84.3% decrease (from a mean [SD] of 3.0 [3.1] to 0.4 [0.8] other vitrectomies) from April 6 to 12, 2020 (95% CI, -3.3 to -1.8 other vitrectomies; P < .001). No differences were identified by region, setting, or state-level stay-at-home order adjustment. Conclusions and Relevance: Although the AAO endorsed the continued performance of urgent or emergent vitreoretinal surgical procedures, the frequency of such procedures throughout the country experienced a substantial decrease that may persist after the COVID-19 pandemic's initial exponential growth phase. This decrease appears independent of region, setting, and state-level stay-at-home orders. It is unknown to what extent vitreoretinal intervention would have decreased without AAO recommendations, and how the decrease is associated with outcomes. Although safety is paramount during the COVID-19 pandemic, practices should consider prioritizing availability for managing high-acuity conditions until underlying reasons for the reduction are fully appreciated.

Posterior pigment dispersion is a rare ophthalmic finding that has been reported in patients undergoing retinectomy with silicone oil placement and in patients who underwent significant anterior segment manipulation and vitrectomy. The pigment release is believed to occur from retinal pigment epithelium (RPE) cells in the former and the posterior iris in the latter. The exact timing of this pre-retinal pigment deposition is unknown but typically is mild and occurs over several months. A rapid progression of diffuse preretinal pigmentation is uncommon and may be suggestive of persistent RPE release from an open break or continued iris trauma with posterior pigment release. This report describes a case of profound posterior pigment deposition more than 4 months after retinectomy and oil in a patient with a persistently open retinectomy edge with anterior retinal detachment. The rapidity of pigment deposition was the clue to recognizing this subtle anterior detachment under silicone oil. [Ophthalmic Surg Lasers Imaging Retina. 2021;52:47-49.].

PURPOSE: To report the surgical technique and outcomes for adjustable ptosis correction using a posterior levator advancement with minimal superior tarsectomy. METHODS: A retrospective single-center study was conducted on patients who underwent adjustable ptosis repair via posterior levator advancement with minimal superior tarsectomy by a single surgeon from 2002 to 2018. Patients with greater than 1 mm asymmetry between eyes or contour abnormalities underwent nonsurgical adjustment in the office within 6 days of surgery. RESULTS: A total of 79 patients (146 eyelids) were included in this study. The patients were female (67%), underwent bilateral surgery (87%) with mean age of 63 years (range, 20-92). The mean improvement in marginal reflex distance 1 at postoperative month 1 was 2.56 ± 1.04 mm (p ≤ 0.0001). Postoperative symmetry of 1 mm or less between eyes was achieved in 96.6% of patients. Only 8 eyes (5.4%) underwent in-office adjustment postoperatively. No demographic or clinical differences were noted in eyes that required adjustments. Postoperative complications included dry eyes that resolved by 3 months (13.6%), suture cyst (1.4%), corneal abrasion (1.4%), and persistent eyelid edema (1.4%). Surgical revision was required in 2.8% of eyes. CONCLUSIONS: The adjustable posterior levator advancement with minimal superior tarsectomy is an effective surgical technique for ptosis repair with the added benefit of in-office adjustability to correct minor asymmetries.

PURPOSE: To evaluate the efficacy in degree of ptosis correction achieved by single suture Müeller muscle conjunctival resection (ssMMCR) when compared with that of traditional MMCR. METHODS: A retrospective chart analysis of patients who underwent either ssMMCR or traditional MMCR at 2 institutions. Single suture MMCR was performed after using a ptosis clamp to imbricate conjunctiva and Müeller muscle. Margin-to-reflex distance 1 was measured pre- and postoperatively, and the change in margin-to-reflex distance 1 was analyzed for both groups. Patients were monitored in follow up for postoperative complications including lagophthalmos, corneal abrasions, and change in visual acuity. Statistical analysis was performed using the Microsoft Excel and Stata software programs. RESULTS: Twenty-seven and 30 patients underwent single suture and traditional MMCR, respectively. The ssMMCR and MMCR groups were followed postoperatively for approximately 4.2 and 9.7 months, respectively and the average margin-to-reflex distance 1 increased by 2.93 mm and 2.81 mm, respectively. Notably, there was no statistically significant difference in the means identified by t test. Of the 94 eyelid surgeries evaluated, 1 ssMMCR and 3 MMCR eyelids required further surgical revision for persistent ptosis, and 1 ssMMCR developed a transient corneal epithelial abrasion. Surgical revisions were rare with both procedures, and patient satisfaction was high. CONCLUSIONS: Single suture MMCR is an efficient and effective method for ptosis repair. It results in comparable outcomes including elevation in margin-to-reflex distance 1, safety profile, and reoperation rates, when compared with traditional MMCR.

PURPOSE: To study whether the ERG and other clinical findings help to distinguish between advanced hydroxychloroquine (HCQ) retinopathy and pericentral or diffuse retinitis pigmentosa (RP) with similar fundus appearance. METHODS: We conducted a retrospective analysis of patients with advanced HCQ retinopathy (n = 11), pericentral RP (n = 8) and diffuse RP (n = 8). Pericentral RP was defined as having limited fundus damage and relatively normal flicker ERG time-to-peak. Diffuse RP had typical loss of the rod ERG and flicker timing delay. All patients showed reduced amplitude of the ISCEV responses in the full-field electroretinogram (ERG). Aspects of history, visual field results, fundus appearance, fundus autofluorescence and ocular coherence tomography were also compared. RESULTS: Relative to pericentral RP, patients with HCQ toxicity showed delayed flicker ERG time-to-peak and lower ERG amplitudes, particularly combined rod-cone responses. Relative to diffuse RP, most HCQ toxicity patients had some preserved rod ERG response, and there was no obvious predilection for rod over cone damage. In addition, patients with HCQ toxicity usually lacked markers of long-standing degeneration such as bone spicule figures or severe loss of peripheral field. History of familial disease and long-standing night blindness were specific to RP. CONCLUSIONS: While the early signs of HCQ damage are typically regional in the posterior pole, advanced disease is characteristically diffuse (unlike pericentral RP). This is appropriate for a systemic toxin, as is the finding that rods and cones were both affected in the ERG to a similar degree (unlike genetic rod-cone dystrophies). For patients with severe HCQ exposure and some of our discriminatory findings, and no family history or prior night blindness, HCQ toxicity is a sufficient diagnosis without invoking a second rare disease (Occam's razor).
