Objective: To describe presenting clinical features and surgical techniques that are associated with successful surgical repair of pediatric rhegmatogenous retinal detachment (RRD). Design: Retrospective interventional case series. Subjects: 212 eyes of 191 patients, aged 0–18 years, undergoing surgical repair for RRD between 2001 and 2015 with a minimum follow up of 3 months. Methods: Patients were divided into three age groups (0–6 years, 7–12 years, 13–18 years) and comparisons were made using bivariate and multivariable generalized estimating equation models. A mixed means model was used to examine visual acuity in each age group over time. Main Outcome Measures: Complete reattachment of the retina at final follow up. Results: Of a total of 212 eyes, 166 (78%) achieved total reattachment at final follow up. Mean follow up was 36.3 months. RRD associated with Stickler syndrome was more likely to occur in the younger cohorts (odds ratio [OR] 0.45, 95 % confidence interval [CI] 0.22 – 0.91), while RRD associated with blunt trauma was more likely to occur in the oldest cohort (OR 2.3, 95% CI 1.2–4.4). Subtotal RRD was more likely to be successfully repaired than total RRD (OR 3.6, 95% CI 1.5 – 8.4, p = 0.0100), and eyes with previous vitreoretinal surgery were less likely to have successful repair (OR 0.30, 95% CI 0.12 – 0.78, p = 0.0258). There was no significant difference between age groups in the rate of surgical success (p = 0.55). There was a significantly higher success rate with primary scleral buckle (SB) (63%, OR 2.2, 95% CI 1.1–4.5) and combined scleral buckle/vitrectomy (SB/PPV) (68%, OR 2.3 95% CI 1.1–5.1) compared to vitrectomy (PPV) alone (51%). Conclusions: Most pediatric patients with RRD achieved complete reattachment with surgery. Success was more common in patients with a subtotal RRD at presentation. Previous vitreoretinal surgery was a risk factor for failure. Younger patients were more likely to present with RRD involving the macula but there was no difference between age groups in successful reattachment at final follow up. Primary PPV had a lower rate of success than SB or combined SB/PPV.

Purpose To describe the fundus autofluorescence (FAF) features of the inflammatory maculopathies and develop a quantification method for FAF analysis. Methods This is a retrospective, consecutive case series of patients with inflammatory maculopathies from two tertiary centers. The clinical findings, demographics, and FAF imaging characteristics were reviewed. Foveal autofluorescence (AF) was analyzed. Median and standard deviation (SD) of foveal AF intensity were measured. Results Thirty eyes of 15 patients were evaluated with both qualitative and quantitative FAF analysis. In acute macular neuroretinopathy, the active phase showed foveal hypoautofluorescence, which became hypoautofluorescent with resolution. In acute posterior multifocal placoid pigment epitheliopathy, multiple lesions with hypoautofluorescent centers with hyperautofluorescent borders were observed in active disease and became hypoautofluorescent with disease convalescence. In multifocal choroiditis and punctate inner choroiditis, the active hyperautofluorescent lesions progressed to inactive, hypoautofluorescent scars. Active serpiginous choroiditis showed hyperautofluorescent borders adjacent to a helicoid-shaped, hypoautofluorescent scar. Active unilateral acute idiopathic maculopathy (UAIM) showed a complex pattern of hypo- and hyperautoflourescence in the macula. The median foveal AF was the greatest in acute macular neuroretinopathy and UAIM among the maculopathies, while the greatest SD of foveal AF intensity was observed in UAIM. Conclusion The active phase of the majority of inflammatory maculopathies was characterized by hyperautofluorescent lesions. Increased SD of foveal AF correlated with a mixture of hypo-and hyperautoflourescence. Median and SD may be useful metrics in foveal AF and quantifiable values that may be assessed over time as a disease process evolves. Improvements in quantification methods of FAF imaging may allow us to objectively evaluate posterior uveitis.

Purpose: To assess the retinal anatomy and array position in Argus II retinal prosthesis recipients. Design: Prospective, noncomparative cohort study. Methods: SETTING: International multicenter study. PATIENTS: Argus II recipients enrolled in the Post-Market Surveillance Studies. PROCEDURES: Spectral-domain optical coherence tomography images collected for the Surveillance Studies (NCT01860092 and NCT01490827) were reviewed. Baseline and postoperative macular thickness, electrode-retina distance (gap), optic disc–array overlap, and preretinal membrane presence were recorded at 1, 3, 6, and 12 months. MAIN OUTCOME MEASURES: Axial retinal thickness and axial gap along the array's long axis (a line between the tack and handle); maximal retinal thickness and maximal gap along a B-scan near the tack, midline, and handle. Results: Thirty-three patients from 16 surgical sites in the United States and Germany were included. Mean axial retinal thickness increased from month 1 through month 12 at each location, but reached statistical significance only at the array midline (P =.007). The rate of maximal thickness increase was highest near the array midline (slope = 6.02, P =.004), compared to the tack (slope = 3.60, P <.001) or the handle (slope = 1.93, P =.368). The mean axial and maximal gaps decreased over the study period, and the mean maximal gap size decrease was significant at midline (P =.032). Optic disc–array overlap was seen in the minority of patients. Preretinal membranes were common before and after implantation. Conclusions: Progressive macular thickening under the array was common and corresponded to decreased electrode-retina gap over time. By month 12, the array was completely apposed to the macula in approximately half of the eyes.

Purpose: To report results of aflibercept therapy in eyes with neovascular age-related macular degeneration previously treated with bevacizumab, ranibizumab, or both. Design: Retrospective, interventional, noncomparative, consecutive case series. Methods: Ninety-six eyes from 85 patients with neovascular age-related macular degeneration who previously had received bevacizumab, ranibizumab, or both were treated with aflibercept monthly for 3 months followed by a fourth injection within 2 months. Outcomes were determined 4 ± 1 months after the first aflibercept dose and included: proportion of patients gaining or losing 2 lines or more of best-corrected visual acuity, proportion remaining within a gain or loss of 1 line, mean change in logarithm of the minimal angle of resolution visual acuity, mean change in central foveal thickness, mean change in macular cube volume, and qualitative anatomic response as assessed by spectral-domain optical coherence tomography. Results: At baseline, 82 (85%) eyes had signs of active exudation despite a mean of 17 previous anti-vascular endothelial growth factor injections. At final visit, 82 (85%) remained stable within a gain or loss of 1 line, 7 (7%) gained 2 lines or more, and 7 (7%) lost 2 lines or more of best-corrected visual acuity. Mean logarithm of the minimal angle of resolution visual acuity showed minimal change 0.02 (range, -0.46 to 0.70; P =.14). Mean central foveal thickness decreased -18 μm (range, -242 to 198 μm; P =.06). Mean macular volume decreased -0.27 mm3 (95% confidence interval, -0.4 to -0.1 mm3; P =.004). On qualitative analysis, 4 (5%) eyes had complete resolution of exudative fluid, 40 (49%) showed partial resolution, 26 (32%) remained unchanged, and 12 (14%) showed worsened exudative fluid. Conclusions: Aflibercept seems to be an effective alternative for neovascular age-related macular degeneration patients previously treated with bevacizumab, ranibizumab, or both at 4 months of follow-up. Most treated eyes demonstrated stable visual acuity and anatomic improvements by spectral-domain optical coherence tomography.

Ceroid lipofuscinosis type 8 belongs to a heterogenous group of vision and life-threatening neurodegenerative diseases, neuronal ceroid lipofuscinosis (NCL). Effective therapy is limited to a single drug for treatment of ceroid lipofuscinosis type 2, necessitating animal disease models to facilitate further therapeutic development. Murine models are advantageous for therapeutic development due to easy genetic manipulation and rapid breeding, however appropriate genetic models need to be identified and characterized before being used for therapy testing. To date, murine models of ocular disease associated with ceroid lipofuscinosis type 8 have only been characterized in motor neuron degeneration mice.

Purpose: To test the effects of an encapsulated cell-based delivery of a neuroprotective agent, ciliary neurotrophic factor (CNTF), on progression of macular telangiectasia type 2, a neurodegenerative disease with no proven effective therapy. Design: Randomized sham-controlled clinical trial. Participants: Ninety-nine study eyes of 67 eligible participants were enrolled. Methods: Single-masked randomized clinical trial of 24 months’ duration conducted from May 2014 through April 2017 in 11 clinical centers of retinal specialists in the United States and Australia. Participants were randomized 1:1 to surgical implantation of intravitreal sustained delivery of human CNTF versus a sham procedure. Main Outcome Measures: The primary outcome was the difference in the area of neurodegeneration as measured in the area of the ellipsoid zone disruption (or photoreceptor loss) measured on spectral-domain (SD) OCT images at 24 months from baseline between the treated and untreated groups. Secondary outcomes included comparison of visual function changes between treatment groups. Results: Among the 67 participants who were randomized (mean age, 62±8.9 years; 41 women [61%]; 58 white persons [86%]), 65 (97%) completed the study. Two participants (3 study eyes) died and 3 participants (4 eyes) were found ineligible. The eyes receiving sham treatment had 31% greater progression of neurodegeneration than the CNTF-treated eyes. The difference in mean area of photoreceptor loss was 0.05±0.03 mm 2 (P = 0.04) at 24 months. Retinal sensitivity changes, measured using microperimetry, were correlated highly with the changes in the area of photoreceptor loss (r = 0.86; P < 0.0001). The mean retinal sensitivity loss of the sham group was 45% greater than that of the treated group (decrease, 15.81±8.93 dB; P = 0.07). Reading speed deteriorated in the sham group (–13.9 words per minute) with no loss in the treated group (P = 0.02). Serious adverse ocular effects were found in 2 of 51 persons (4%) in the sham group and 2 of 48 persons (4%) in the treated group. Conclusions: In participants with macular telangiectasia type 2, a surgical implant that released CNTF into the vitreous cavity, compared with a sham procedure, slowed the progression of retinal degeneration. Further research is needed to assess longer-term clinical outcomes and safety.

Purpose: This study examines the impact of corneal surface lubricants used during pars plana vitrectomy on corneal edema. Methods: This prospective, observational, clinical study occurred at an academic institution. Participants were individuals aged 18 years and older who had already consented to undergo pars plana vitrectomy, without pre-existing corneal pathology. A corneal lubricant was chosen by the surgeon. Corneal thickness was measured preoperatively and postoperatively using pachymetry and anterior segment optical coherence tomography (AS-OCT). Main outcome measure was change in corneal thickness as measured by pachymetry. Results: Forty-one patients completed the study protocol. The 23 subjects in the SHCS group had a significantly smaller increase in corneal thickness as measured by pachymetry compared with the 18 subjects in the HPMC group (29.9 mm vs. 58.1 mm, P value 0.02). When measured by anterior segment optical coherence tomography, the SHCS group had a smaller increase in corneal thickness compared with the HPMC group (0.04 mm vs. 0.06 mm, P value 0.09) but did not reach significance. Conclusion: SHCS is associated with reduced postoperative increase in corneal pachymetry as compared to HPMC.

Animal studies suggest that the retinal dysfunction in diabetic subjects that precedes overt clinical vasculopathy may be due to a retinal dopamine deficit. We analyzed levels of dopamine (DA) and its primary metabolite, 3,4-dihydroxyphenylacetic acid (DOPAC), in the vitreous of diabetic and non-diabetic human subjects. Adult patients undergoing pars plana vitrectomy for non-hemorrhagic indications were prospectively recruited from the Emory Eye Center in Atlanta, GA. Vitreous samples were analyzed using high performance liquid chromatography (HPLC) to measure levels of DOPAC and DA in the vitreous specimens. Vitreous samples from 9 diabetic patients and 20 from non-diabetic patients were analyzed. No eyes had apparent diabetic retinopathy. Mean normalized DA concentration in vitreous of diabetic subjects was 0.76 ± 0.12 pg/μL vs. 0.73 ± 0.08 pg/μL in non-diabetic vitreous (p = 0.849). DOPAC concentration was 8.84 ± 0.74 pg/μL in vitreous of diabetic subjects vs. 9.22 ± 0.56 pg/μL in vitreous of non-diabetic subjects (p = 0.691). No difference was observed in the concentrations of DA and DOPAC in the vitreous of people without diabetes compared to those with diabetes without retinopathy.

To report a rare presentation of the pericentral pattern of hydroxychloroquine (HCQ) retinal toxicity in a Caucasian female. Observations: The patient presented with 20 years of exposure to HCQ, at a daily dose of 5.2mg/kg of actual body weight, and manifested a pericentral-only phenotype of HCQ toxicity, as demonstrated with detailed structural and functional testing. Conclusions and importance: Although rare, the pericentral pattern of HCQ toxicity may occur in Caucasian patients in the absence of paracentral changes.

Purpose: To report atypical presentation of neuronal ceroid lipofuscinoses type 8 (CLN8) to the eye clinic and review clinical features of CLN8. Observations Detailed eye exam by slit lamp exam, indirect ophthalmoscopy, fundus photography, optical coherence tomography, visual fields and electroretinogram (ERG). Molecular genetic testing using Next Generation Sequencing panel (NGS) and array Comparative Genomic Hybridization (aCGH). The siblings in this study presented to the eye clinic with retinitis pigmentosa and cystoid macular edema, and a history of seizures but no severe neurocognitive deficits or regression. Genetic testing identified a c.200C  >  T (p.A67V) variant in the CLN8 gene and a deletion encompassing the entire gene. Electron microscopy of lymphocytes revealed fingerprint inclusions in both siblings. Conclusions and Importance: Pathogenic variants in CLN8 account for the retinitis pigmentosa and seizures in our patients however, currently, they do not have regression or neurocognitive decline. The presentation of NCL can be very diverse and it is important for ophthalmologists to consider this in the differential diagnosis of retinal disorders with seizures or other neurological features. Molecular genetic testing of multiple genes causing isolated and syndromic eye disorders using NGS panels and aCGH along with additional complementary testing may often be required to arrive at a definitive diagnosis.
