Analysis of Posterior Vitreous Detachment and Development of Complications Using a Large Database of Retina Specialists.

PURPOSE: To examine the incidence of complications after posterior vitreous detachment (PVD) through an extended follow-up period and to identify patient-specific factors associated with a greater incidence of complication. DESIGN: Multicenter, retrospective observational study. PARTICIPANTS: Eyes with acute PVDs between 2015 and 2019 were identified through the Vestrum Health database. METHODS: Complications (vitreous hemorrhage, retinal break, and retinal detachment) were evaluated after acute PVD at presentation and throughout the 6-month follow-up period. MAIN OUTCOME MEASURES: Rate of complications throughout the 6 month follow-up period after PVD and odds of complications by patient-specific factors. RESULTS: A total of 9635 eyes were included. The rate of any complication was 25.0%, isolated vitreous hemorrhage was 13.1%, retinal breaks without detachment was 16.0%, and retinal detachment was 4.2%. The majority of each complication was noted at presentation; however, 8.0% of isolated vitreous hemorrhages, 19.2% of retinal breaks without detachment, and 25.8% of retinal detachments were first noted within the 6-month follow-up period. Men experienced a significantly higher rate of any complication than women (30.0% versus 21.7%, P < 0.001), as well as retinal breaks and retinal detachments at both presentation and within 6-month follow-up. Patients with pseudophakia experienced significantly higher rates of delayed retinal detachment than phakic eyes (odds ratio, 1.85 [1.13, 3.04], P = 0.01). Among eyes with lattice/peripheral retinal degeneration, 44.2% experienced any complication throughout the clinical course. The presence of a retinal break in the fellow eye and retinal detachment in the fellow eye was associated with a significantly increased rate of any complication at any time point (retinal break: P < 0.0001; retinal detachment: P = 0.02), as well as each individual complication within the 6 month follow-up period. Among eyes with vitreous hemorrhage at presentation, 42.0% had a concurrent or delayed retinal break and 10.5% had concurrent or delayed retinal detachments. CONCLUSIONS: A clinically significant proportion of PVD-related complications are detected late, warranting extended follow-up, especially in higher-risk groups such as men, pseudophakic eyes, eyes with lattice/peripheral retinal degeneration, and eyes with a history of retinal breaks or detachment in the fellow eye.

VITREOUS SEEDING OF RENAL CELL CARCINOMA IN A PATIENT RECEIVING CHECKPOINT INHIBITORS.

PURPOSE: To describe a case of vitreous seeding with tractional retinal detachment as a result of metastatic renal cell carcinoma in a patient on systemic checkpoint inhibitors. METHODS: Case report. RESULTS: A 44-year-old Hispanic woman with a history of renal cell carcinoma with metastases to the lungs, adrenal glands, hilar lymph nodes, and peritoneum presented with a complaint of severe floaters and blurry vision of the right eye for two months. She was found to have dense, web-like vitreous opacities and a peripheral tractional retinal detachment of the right eye. Pars plana vitrectomy, membrane peeling, endolaser, air-fluid exchange, gas injection, and vitreous biopsy were performed. The vitreous and membranes were sent for cytology with stains, including AE1/AE3, PAX-8, CK-7, CA-IX, AMACR, and S-100. Cytology revealed crowded groups of glandular cells, some in papillary-like formations. Positive stains included AE1/AE3, PAX-8, CK-7, CA-IX, and AMACR. CONCLUSION: Cytology and pathology demonstrated that vitreous seeding of metastatic renal cell carcinoma without an ocular mass lesion. It is hypothesized that the use of checkpoint inhibitors played a role in allowing for the atypical and previously unreported seeding of renal cell carcinoma to the vitreous.

LONG-TERM VISUAL RECOVERY IN BILATERAL HANDHELD LASER POINTER-INDUCED MACULOPATHY.

PURPOSE: To describe the long-term visual, clinical, and optical coherence tomography (OCT) recovery after 4 years in a patient who incurred severe bilateral handheld laser pointer damage. METHODS: The findings on clinical examination, color fundus photography, and spectral domain OCT at presentation followed by sequential time points over 4 years are presented. RESULTS: A 9-year-old healthy boy presented with bilateral reduced vision to count fingers in each eye with yellow irregular lesions. After extensive evaluation, he admitted to multiple, prolonged episodes of staring at a handheld red laser pointer reflected in a mirror. Initial visual acuity was count fingers bilaterally. Clinical examination revealed bilateral yellow streaks radiating from the fovea without hemorrhages or fluid and retinal pigment epithelium pigmentary mottling. Spectral domain OCT showed disruption of the foveal outer retina extending from the outer plexiform layer to the retinal pigment epithelium spanning 896 µm in the right eye and 564 µm in the left eye. Six months after injury, vision had only minimally improved to 20/200 with resolution of outer plexiform layer and outer nuclear layer opacification on OCT. Over the ensuing 4 years, visual acuity slowly recovered to 20/30 in each eye and the regions of outer retinal disruption progressively reduced in size to 295 µm in the right eye and 115 µm in the left eye. CONCLUSION: This case illustrates gradual vision and anatomical improvement over 4 years despite initial poor vision after severe laser pointer macular damage. Visual recovery may be related to patient and exposure factors as well as initial OCT features where an intact Bruch membrane can provide a scaffold for photoreceptors to recover, thereby reducing the outer retinal defect.

PREOPERATIVE DOMED MACULAR CONTOUR CORRELATES WITH POSTOPERATIVE VISUAL GAIN AFTER VITRECTOMY FOR SYMPTOMATIC EPIRETINAL MEMBRANE.

PURPOSE: Evaluate macular features on preoperative ocular coherence tomography as indicators of postoperative visual gain following vitrectomy for epiretinal membrane (ERM). METHODS: A retrospective chart review of 66 eyes that underwent vitrectomy with membrane and internal limiting membrane peeling for symptomatic ERM. Inclusion criteria required a pre-op visual acuity of at least 20/200 and minimum follow-up of 1 year. In addition, 31 of these eyes with complete 5-line raster pre-op ocular coherence tomography had segmentation analysis which included noncentral ERM to inner nuclear layer and ERM to outer plexiform layer measurements. RESULTS: Eyes with "domed" pre-op macular contour had a mean preoperative acuity of 20/70 and gained a mean 2.4 lines at one year, compared with those with "flat" or "depressed" macular contour, having a 20/60 mean preoperative acuity and 0.6 lines gained (P = 0.02). Changes for other ocular coherence tomography features examined were not statistically significant. Paracentral ERM to inner nuclear layer measurements had moderate correlation, whereas paracentral ERM to outer plexiform layer measurements had weak correlation with gain in visual acuity. CONCLUSION: An inner macular-domed contour in eyes with ERM predicted better visual gain after vitrectomy with ERM and internal limiting membrane peeling compared with a flat or depressed contour.

Investigation of goldmann perimetry in evaluation of patients for upper eyelid blepharoplasty.

PURPOSE: To determine if preoperative Goldmann Visual Field (GVF) testing in patients with functional dermatochalasis accurately depicts the postoperative superior visual field (SVF) outcome. METHODS: A prospective cohort study was done to compare preoperative and postoperative GVF field tests in patients undergoing upper eyelid blepharoplasty for treatment of dermatochalasis. This study was conducted in accordance with the Declaration of Helsinki and approved by the University of Arkansas for Medical Sciences institutional review board. A preoperative GVF was obtained with the eyelids in the natural position (untaped) and then again with excess skin elevated (taped). One month post-blepharoplasty, another GVF was conducted with eyelids untaped. The pre- and post GVF tests were analyzed to determine if preoperative testing accurately predicts the SVF improvement post-blepharoplasty. RESULTS: Forty-six eyelids (23 patients) who underwent blepharoplasty for dermatochalasis were included. The preoperative testing underestimated 76% (35/46) of cases by a mean of 61%; and overestimated the final outcome in 24% (11/46) of cases by mean of 23%. Overall, the preoperative GVF testing underestimated the postoperative outcome by a mean of 35%. CONCLUSION: Improvement of the SVF after a blepharoplasty is typically greater than the preoperative GVF testing predicts.
