RESUMEN
PURPOSE: To compare results of two ophthalmic viscosurgical devices (OVDs)-Viscoat (a dispersive OVD, Alcon) and FR-Pro (a viscous-cohesive OVD, Rayner), in phacoemulsification surgery. METHODS: A prospective randomized controlled study. Patients undergoing phacoemulsification were randomly assigned to receive one of the two OVDs. Exclusion criteria were age under 40, preoperative endothelial cell count (ECC) below 1,500 cells/mm2 and an eventful surgery. The primary outcome was change in ECC from baseline to postoperative month one and month three. Secondary outcomes were the difference between ECC at postoperative month one and month three, changes in IOP and occurrence of an IOP spike ≥ 30 mmHg after surgery. RESULTS: The study included 84 eyes-43 in the Viscoat group and 41 in the FR-Pro group. Mean cell density loss at month one and month three was 17.0 and 19.2%, respectively, for the Viscoat group and 18.4 and 18.8%, respectively, for the FR-Pro group, with no statistically significant difference between the groups (p = 0.772 and p = 0.671, respectively). The mean ECC difference between the month one and month three visits was 50.5 cells/mm2 and was not statistically significant (p = 0.285). One eye in each group had an IOP spike ≥ 30 mmHg, both normalized by postoperative week one. CONCLUSIONS: Viscoat and FR-Pro have comparable results following phacoemulsification surgery, suggesting that while FR-Pro is not a dispersive OVD, its endothelial cell protection may be comparable to one, perhaps due to the addition of sorbitol. Furthermore, a one-month follow-up of ECC seems sufficient in such trials.

BACKGROUND: Little is known about the success of multidisciplinary thyroid eye disease (TED) clinic. OBJECTIVES: To present the characteristics, treatments, and outcomes of patients treated in a multidisciplinary TED clinic. METHODS: A medical record review of all patients who attended a TED clinic was performed. Data included demographics, medical history, laboratory tests, visual function tests, ocular examinations, clinical activity score (CAS), and assessment of quality-of-life (QOL). RESULTS: Clinic visits included 132 patients seen during 385 appointments at a TED clinic (mean 12 appointments per patient). Management of TED included medical treatments for 48 patients (36.3%) and surgical treatment for 56 (42.4%). There was a positive significant correlation between the CAS and thyroid-stimulating immunoglobulin (TSI) activity at the first visit and at the last follow-up visit (P < 0.01 and P < 0.02, respectively). However, no correlation was found between the CAS and the thyroid-stimulating hormone levels or between the free triiodothyronine (fT3) and fT4 levels at the first or last visit. There was a significant negative correlation between the CAS and color vision (-0.347, P < 0.01, Pearson correlation) at the first visit, but not between the CAS and visual acuity and visual field at either the first or last visit. Changes in the QOL and the CAS scores were significantly negatively correlated (-0.240, P < 0.01). CONCLUSIONS: Treatment and management decisions for TED should be based on multiple parameters including clinical examinations by ophthalmologists and endocrinologists, laboratory tests, and CAS and QOL scores.

Silent sinus syndrome (SSS) is a rare condition characterized by enophthalmos and hypoglobus that is generally not related to trauma or surgery. We present a 30-year-old man who noticed facial asymmetry during the previous month and was referred to our oculoplastic clinic. His examination revealed right hypoglobus and a 2-mm right enophthalmos. The diagnosis of right SSS was confirmed by orbital and paranasal computed tomography scan. The patient had no otolaryngological symptoms and visual acuity was normal bilaterally. He was treated surgically in a combined approach by a team of oculoplastic and otorhinolaryngology surgeons. Functional endoscopic sinus surgery included uncinectomy, maxillary antrostomy, and orbitotomy, with insertion of an orbital implant. This case demonstrates that a single-step surgery for correction of enophthalmos secondary to SSS is a viable option, leading to quick rehabilitation and excellent aesthetic results.
