Retinal Pigment Epithelial Adenoma: Initial Treatment Outcomes following Episcleral Brachytherapy.

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.

Bilateral Morning Glory Syndrome with Bilateral Persistent Fetal Vasculature in a Patient with Joubert's Syndrome.

Purpose. We report a case of a 1-year-old girl who was referred to us with a cerebellar anomaly and delayed growth and development for bilateral ptosis and poor fixation. Based on our ophthalmologic examination, we concluded that she has bilateral persistent fetal vasculature (PFV) with morning glory syndrome (MGS). A closer look into her neurologic condition revealed that she has Joubert's syndrome. Observations. External examination revealed bilateral symmetrical ptosis with syndromic facies and her fundus examination revealed a large dysplastic optic disc with anomalous radiating vessels and a fibrous tissue tuft originating from the disc. The left eye showed similar findings in addition to a central excavation and a fibrovascular stalk extending from the optic disc. These findings were consistent with bilateral MGS and bilateral PFV. The brain imaging included a computed tomography scan and magnetic resonance imaging, both of which revealed a "molar tooth appearance" of the midbrain and an anomalous cerebellum suggestive of Joubert's syndrome. Conclusions and Importance. This is the first case report of a case of bilateral MGS and bilateral PFV associated with Joubert's syndrome. This case report documents the associated optic nerve disease in these patients, not previously described, which are additive causes of visual compromise in addition to the brain insult.

The value of prednisolone acetate provocative test before intravitreal triamcinolone acetonide injections.

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.
