RESUMO
BACKGROUND: Posterior scleritis is one of the most easily missed and misdiagnosed diseases in ophthalmology. In this case we treated a patient with intravitreal dexamethasone implant that has not been extensively studied before. CASE SUMMARY: A 40-year-old female patient who had anxiety, palpitation, and insomnia presented with eye pain and decreased vision in the left eye. An eye examination indicated that her visual acuity (VA) was 40/100. Her left eye presented conjunctival edema, mild exophthalmos, clear cornea, KP(-), and clear aqueous humor. In the fundus, there was a cinerous retinal protuberance. Ultrasonography showed "T-sign" and no systemic association was detected in laboratory examination. One month after injection of dexamethasone implant, the patient exhibited VA of 20/20, fundus serous retinal detachment disappeared, and intraocular pressure of both eyes was at the normal level. CONCLUSION: Intravitreal injection of dexamethasone implant may be a safe and effective treatment for patients with idiopathic posterior scleritis.
RESUMO
PURPOSE: To evaluate the long-term outcomes of ciliary sulcus versus capsular bag fixation of intraocular lenses (IOLs) in children after pediatric cataract surgery. METHODS: IOL was implanted in the ciliary sulcus in 21 eyes of 14 children, and in the capsular bag in 19 eyes of 12 children for the treatment of pediatric cataract in an institutional setting. Ultrasound biomicroscopy (UBM) was performed. Main outcome measures included IOL decentration, IOL tilt, anterior chamber depth (ACD), angle-opening distance at 500 µm (AOD500), trabecular-iris angle (TIA), best-corrected visual acuity (BCVA), intraocular pressure (IOP), and incidence of postoperative complications. RESULTS: The mean follow-up period was 6.81 ± 1.82 years. Comparing to the capsular bag fixation group, the ciliary sulcus fixation group had higher vertical IOL decentration, horizontal IOL tilt, and vertical IOL tilt (p = 0.02, 0.01,0.01, respectively), higher incidence of iris-IOL contact and peripheral anterior synechia (p = 0.001, 0.03, respectively), smaller ACD, AOD500, and TIA (p = 0.02, 0.03, 0.04, respectively), higher mean IOP (17.10 ±6.06 mmHg vs.14.15± 4.74 mmHg, p = 0.01), and higher incidence of secondary glaucoma (28.57% vs. 10.53%, p = 0.007).There was no significant difference between the two groups with regard to the BCVA, refractive errors, incidence of myopic shift, nystagmus, strabismus, and visual axis opacity. CONCLUSIONS: Ciliary sulcus fixation of IOLs in pediatric eyes may increase IOL malposition and crowding of the anterior segment, and may associate with a higher risk of secondary glaucoma compared to capsular bag fixation of IOLs.
