Purpose: The study compares refractive outcomes of secondary intraocular lens (SIOL) surgery performed by vitreoretinal, anterior segment, and both surgeons. Methods: Eyes included in this study underwent SIOL surgery from 2012 to 2024 and had a final postoperative visual acuity of 20/50 or better. Regression analysis compared refractive outcomes, and chi-squared analysis compared complications between subspecialty of SIOL surgeons. Results: A total of 94, 104, and 80 eyes were included in the retina surgeon, anterior segment surgeon, and combo surgeon cohorts, respectively. There was no significant difference in error between target and final postoperative spherical equivalence between retina and combo ( P = 0.079), retina and anterior segment ( P = 0.135), or anterior segment and combo cohorts ( P = 0.567). There was no significant difference in number of eyes with final spherical equivalence within 1 diopter of target spherical equivalence between retina and combo ( P = 0.136), retina and anterior segment ( P = 0.061), or anterior segment and combo cohorts ( P = 0.783). The retina cohort had higher postoperative corneal edema than the combo ( P = 0.017) and the anterior segment cohorts ( P = 0.035). The combo cohort had more postoperative retinal detachment than the anterior segment cohort ( P = 0.046). Conclusion: In eyes with good final vision, retina and anterior segment surgeons have similar refractive outcomes after SIOL surgery.

Purpose: To present a case of a dislocated posterior lamellar graft into the vitreous cavity in an eye that was post pars plana vitrectomy. Methods: Retrospective case report Results: A middle-aged man underwent pars plana vitrectomy (PPV), pars plana lensectomy (PPL), and SSIOL fixation following a traumatic eye injury. The patient required subsequent Descemet stripping automated endothelial keratoplasty (DSAEK) for corneal edema, and the posterior lamellar graft was lost intraoperatively into the posterior segment. The graft was surgically retrieved one week later, followed by a successful placement of a new posterior lamellar graft. Histopathological examination of the retrieved graft after one week in the vitreous cavity revealed viable endothelial cells, a novel finding in a posteriorly dislocated DSAEK graft. The newly placed graft remained attached and healed well, with the patient achieving a visual acuity (VA) of 20/80 at three months post-operatively. Discussion: Posteriorly dislocated grafts may be suitable for transplantation to the corneal stroma following prompt retrieval from the vitreous cavity. Prompt retrieval and appropriate surgical techniques are critical for optimizing outcomes in such clinical scenarios.

When encountering diseases of the anterior vitreous and peripheral retina (ie, the “middle segment” of the eye), vitreoretinal (VR) surgeons are specifically trained in surgical techniques for managing the vitreous and visualizing the peripheral retina during anterior vitrectomy, and therefore, they are well equipped to address the complications of surgery involving the anterior vitreous space. This clinical update reviews and compares the current literature discussing techniques and patient outcomes related to complete pars plana vitrectomy versus incomplete, subtotal pars plana vitrectomy, and addresses the proposition of developing an abridged training curriculum for non-VR surgeons to acquire the knowledge and skills required to perform these procedures. Recent studies confirmed that operating in the anterior vitreous carries potential risk of retinal tear, retinal detachment, and other adverse events that may cause vision loss. To mitigate these risks, studies suggest that the use of dedicated visualization equipment and illumination instruments is necessary for surgeons to safely perform anterior vitrectomy and recognize complications, should any occur. Performing VR surgery in the absence of wide-angle viewing systems, endoillumination, careful peripheral examinations, modern vitrectomy platforms, and appropriate training may lead to outcomes that are detrimental to patient safety.

Background: Retrospective cohort study of 561 adult patients undergoing secondary intraocular lens (IOL) implantation by vitreoretinal surgeons at a single institution from April 2015 to December 2020. Methods: Patient historical factors, intraoperative/postoperative complications, and outcomes of IOL type (anterior chamber IOL versus scleral sutured IOL versus scleral fixated IOL versus. sulcus) were assessed. Primary outcomes were rates of postoperative retinal tears and rhegmatogenous retinal detachment. Secondary outcomes were rates of intraoperative endolaser, intraoperative retinal tear, and further IOL surgery. Results: The incidence of intraoperative retinal tears was 7.3% and not significantly different between techniques. Rates of intraoperative endolaser use were 17.5% among all techniques and not significantly different between techniques. Rates of postoperative retinal tear were low (0%–2.7%). Rates of postoperative rhegmatogenous retinal detachment were not significantly different between techniques (anterior chamber IOL 9/198 [4.5%], SFIOL 1/54 [1.9%], scleral sutured IOL 14/274 [5.1%], sulcus 2/35 [5.7%], total 26/561 [4.6%], P = 0.79). Rates of repeat IOL surgery trended higher in sulcus lenses (anterior chamber IOL 5/198 [2.5%], SFIOL 4/54 [7.4%], scleral sutured IOL 16/274 [5.8%], sulcus 5/35 [14.3%], total 30/561 [5.3%], P = 0.12). Conclusion: Intraoperative endolaser use and intraoperative retinal tear are not uncommon in secondary IOL surgery and underscore the importance of careful vitreoretinal management among these patients.

Purpose: To evaluate anatomic outcomes and surgeon response following the use of microserrated (Sharkskin, Alcon, Forth Worth, TX) internal limiting membrane (ILM) forceps compared with conventional (Grieshaber; Alcon) ILM forceps for peeling of the ILM. Methods: Patients were prospectively assigned in a 1:1 randomized fashion to undergo ILM peeling using microserrated forceps or conventional forceps. Rates of retinal hemorrhages, deep retinal grasps, ILM regrasping, time to ILM removal, and surgeon questionnaire comparing the use of microserrated and conventional ILM forceps were analyzed. Results: A total of 90 eyes of 90 patients were included in this study. The mean number of deep retinal grasps was higher in the conventional forceps group (1.51 ± 1.70 vs. 0.33 ± 0.56, respectively [P < 0.0001]). The mean number of failed ILM grasps was higher with conventional forceps (6.62 ± 3.51 vs. 5.18 ± 2.06 [P = 0.019]). Microserrated forceps provided more comfortability (lower number) in initiating the ILM flap (2.16 ± 0.85 vs. 1.56 ± 0.76, P < 0.001), comfortability in regrasping the ILM flap (2.51 ± 1.01 vs. 1.98 ± 0.89, P = 0.01), and comfortability in completing the ILM flap (2.42 ± 1.03 vs. 1.84 ± 1.02, P = 0.01). Conclusion: Surgeons utilizing the microserrated forceps experienced fewer deep retina grasps and fewer failed ILM grasps compared with conventional ILM forceps. The microserrated forceps was also a more favorable experience subjectively among the surgeons.

Purpose: In this study, the authors aimed to identify the demographics of retinal detachment in children in the United States and to report the treatment modalities chosen by vitreoretinal surgeons and associated outcomes. Methods: This was a multicenter cohort analysis of the Vestrum Health LLC Database (Naperville, IL). Children (1–17 years) with rhegmatogenous retinal detachment, as identified by ICD10 and CPT codes, between January 2015 and August 2021 were enrolled. Demographic, comorbidity, visual acuity, and treatment modality data were analyzed. Results: A total of 168,152 RRDs were identified, of which 2,200 (1.3%) were aged 1 to 17 years. The mean age was 12.7 years, and 821 (37%) were women. The prevalence of rhegmatogenous retinal detachment increased with age (P = 0.009). Associated comorbidities included myopia (17.3%), ocular trauma (7.5%), and history of prematurity (5.7%). Laser retinopexy alone was used as the initial treatment modality in 19%, primary vitrectomy in 23%, primary scleral buckle in 25%, and vitrectomy with scleral buckle in 33%. The single surgery success rate for all procedures was 73.3%. Of the incisional surgical modalities, primary scleral buckling had the best single surgery success rate (79.0%) compared with vitrectomy alone (64.5%) and vitrectomy with scleral buckle (67.2%) (P < 0.001 and P = 0.004, respectively). Younger age resulted in worse SSSR overall (coefficient = 0.151, R2 = 0.746, P = 0.027). Conclusion: Rhegmatogenous retinal detachments in children increased with age. Myopia, trauma, and history of retinopathy of prematurity were common risk factors. Treatment techniques varied, but primary scleral buckling had the best anatomical and visual outcomes.

Purpose: To identify the visual acuity outcomes of patients with age-related macular degeneration treated with intravitreal anti–vascular endothelial growth factor injections over a 10-year period. Methods: This was a retrospective, cohort study of eyes with exudative age-related macular degeneration that received ≥2 intravitreal anti–vascular endothelial growth factor injections and had at least 10 years of follow-up after the initiation of treatment. Snellen visual acuity was recorded at baseline and then annually until the last year of follow-up. Optical coherence tomography data were collected at the time of treatment initiation and at the last examination visit. A subanalysis was performed on patients who continued to receive anti–vascular endothelial growth factor therapy using a modified treat and extend protocol versus those who discontinued treatment for longer than 1 year. Results: One hundred thirty eyes of 115 patients met the inclusion criteria. The mean follow-up after treatment initiation was 11.1 ± 0.7 years. Eyes received an average of 45.1 ± 32.3 intravitreal injections in total and a mean of 5 to 7 injections per year. The baseline mean logMAR visual acuity was 0.61 ± 0.5 (Snellen acuity 20/81), and the final mean logMAR visual acuity was 0.88 ± 0.7 (20/152, P value = <0.0001). There were 40 eyes that received at least one injection every year. These eyes did not have a significant change in visual acuity between the baseline and final examinations 0.47 ± 0.4 (20/59 vs. 0.58 ± 0.5 [20/76, P = 0.28]), whereas the eyes that did not receive at least one injection every year saw a significant decline in visual acuity 0.67 ± 0.5 (20/94 vs. 1.01 ± 0.7 [20/205, P < 0.0001]). Conclusion: Eyes with exudative age-related macular degeneration that received intravitreal injections every year had stable visual acuity over a 10-year period. Continuous intravitreal anti–vascular endothelial growth factor therapy may stabilize visual acuity for 10 years and potentially longer.

Purpose: To describe two patients with giant cell arteritis who presented with macular lesions mimicking persistent placoid maculopathy. Methods: Retrospective case reports. Patient: Two patients, a 74-year-old man and an 85-year-old woman both were diagnosed with biopsy-confirmed giant cell arteritis with vision loss in one eye due to arteritic ischemic optic neuropathy. Both presented many years later with acute vision loss in the remaining eye. Results: Both patients had bilateral retinal whitening in the parafovea, and the second also had sectoral optic disk swelling. On fluorescein angiography, these areas of retinal whitening in both patients were hypofluorescent early with late hyperfluorescence staining. On indocyanine green angiography, there were areas of foveal hypocyanescence bilaterally in both patients that persisted throughout the imaging and were more apparent late. These findings can be seen in patients with bilateral persistent placoid maculopathy. Conclusion: Giant cell arteritis should be included in the differential diagnosis of persistent placoid maculopathy.
