RESUMEN
Introduction: We aim to explore the safety and efficacy of episcleral brachytherapy as a primary management option for eyes with retinal pigment epithelial (RPE) adenoma. Methods: Retrospective chart review of the demographic, clinical, ancillary, and postoperative outcome data of patients with RPE adenoma in 2 tertiary referral centers. Tumor regression, final visual acuity, and complications were assessed. Results: Five patients (3 females and 2 males) were included. Four of the 5 eyes had peripheral and mid-peripheral lesions, while one tumor was juxtapapillary. Three eyes were treated with ruthenium-106 (100 Gray), and 2 received iodine-125 episcleral plaques (85 Gray). All eyes showed clinical and imaging-based evidence of regression. Four eyes had stable or improved visual acuity, while 1 eye exhibited one line loss of visual acuity due to radiation retinopathy. Local recurrence was not observed in any eye over a median follow-up of 24 (range 6-112) months. Conclusions: Episcleral brachytherapy is an effective management option for select cases of RPE adenoma that is capable of achieving tumor regression while maintaining favorable visual acuity. The initial safety profile of brachytherapy is good without significant vision-compromising complications.
RESUMEN
PURPOSE: The optimal management of pediatric traumatic macular holes (TMH) is unclear from lack of prospective randomized trials. The literature is divided into early (≤1month post-trauma), delayed (>1 month) pars plana vitrectomy (PPV), and observation. Our aim is to find which group can achieve best-superior spectacle corrected visual acuity (VA), visual gain, and time for hole closure. DESIGN: Systematic review. METHODS: This systematic review was registered with PROSPERO (ID:CRD42022383134). The databases searched from inception until July 31, 2023, were MEDLINE OVID, Scopus, Web of Science, Embase, and Google Scholar. The articles were screened for title and abstract then for full text. Risk of bias was also assessed. Three outcome measures were analyzed: final VA, visual gain, and time to closure of macular hole (MH). MH size was divided into small (≤250 µm), medium (>250-500 µm), and large (>500 µm). RESULTS: Ninety eight (98) studies with 234 patients in the PPV group and 87 patients in the observation group were included in the review. Final VA (logarithm of the minimum angle of resolution) and visual gain were respectively in PPV vs observation groups: (1) small MH 0.37 ± 0.52 vs 0.42 ± 0.56 (P = .484) and -0.96 ± 0.83 vs -0.49 ± 0.40 (P = .005); (2) medium MH 0.58 ± 0.39 vs 0.34 ± 0.34 (P = .06) and -0.36 ± 0.42 vs -0.74 ± 0.44 (P < .001); (3) large MH 0.62 ± 0.42 vs 0.59 ± 0.35 (P = .337) and -0.31 ± 0.48 vs -0.62 ± 0.37 (P = .11). Small TMH had comparable closure time: 3.21 ± 2.52 months vs 3.49 ± 4.43 (P = .954) in the PPV and observation groups. Early and late PPV yielded comparable final VA 0.67 ± 0.66 vs 0.54 ± 0.35 (P = .576) and visual gain -0.58 ± 0.69 vs -0.49 ± 0.48 (P = .242) in the PPV and observation groups. CONCLUSIONS: PPV was very effective in closing TMH and VA gain in children throughout a wide range of hole size. Early and delayed PPV yielded similar anatomic and visual results. Observation and PPV yielded comparable final VA and closure time. Clinicians can choose either early PPV or delayed PPV when healing biomarkers are absent on periodic optical coherence tomography.
RESUMEN
PURPOSE: We aimed to identify the risk factors that may predispose preterm neonates to develop aggressive posterior retinopathy of prematurity (APROP). METHODS: This retrospective case control study included 16 infants with APROP in zone 1 or posterior zone 2. Thirty-four gestational age and birth weight-matched controls with stage 2 or less ROP were included. We reviewed medical records on infant birth and postnatal characteristics. RESULTS: Patients who developed APROP had a significantly longer duration of caffeine therapy, were significantly more likely to be small for gestational age (SGA), and were more likely to have a positive blood culture than patients who developed less severe ROP. Patients with APROP who required retreatment had received inotropes for a longer duration of time, had received more plasma transfusions, were more likely to have IVH, and had a greater decrease in the serum hemoglobin during hospitalization. CONCLUSION: Being SGA, receiving caffeine for a longer duration, and having culture-proven sepsis were associated with APROP. IVH, a low serum hemoglobin, the need for more plasma transfusions, and a longer duration of inotropes were associated with APROP which required retreatment.
RESUMEN
PURPOSE: The aim of this study was to investigate the diagnostic value of a topical prednisolone acetate 1% provocative test for steroid-induced ocular hypertension before intravitreal triamcinolone acetonide injection. METHODS: This is a prospective, single-center, randomized controlled study at Kasr El Aini Hospital, Cairo University. Patients scheduled for intravitreal triamcinolone acetonide were enrolled and randomly allocated in a ratio 2:1 to either Group A: received prednisolone acetate provocative test and those who did not develop SIOH proceeded with intravitreal triamcinolone acetonide or Group B: did not receive prednisolone acetate provocative test and proceeded directly to intravitreal triamcinolone acetonide. Intraocular pressures were measured weekly for 4 weeks following intravitreal triamcinolone acetonide. Steroid-induced ocular hypertension is defined as intraocular pressure increase of 5 mmHg or more from baseline after prednisolone acetate provocative test or intravitreal triamcinolone acetonide. RESULTS: A total of 66 eyes (66 patients) were included. Of which, 10 eyes (23.8%) showed prednisolone acetate provocative test steroid-induced ocular hypertension during the 4-week period. Intravitreal triamcinolone acetonide steroid-induced ocular hypertension was less likely to develop in Group A (prednisolone acetate provocative test non-steroid-induced ocular hypertension, n = 32, 31.25%) than in group B (n = 24, 54.2%) (p = 0.006, odds ratio: 0.178, 95% CI: 0.53-0.596). Our test achieved a negative predictive value of 68.75%. CONCLUSION: The topical prednisolone acetate provocative test may be a useful method to predict a steroid-induced ocular hypertension following intravitreal triamcinolone acetonide.
