RESUMEN
Bilateral optic disc edema in a diabetic patient may be caused by diabetic papillopathy. We herein report on a patient with bilateral optic disc drusen simulating diabetic papillopathy. A 55-year-old patient with type 2 diabetes presented with decreased vision of 1-month. Diabetic papillopathy was initially considered as there was disc edema in both eyes with focal hemorrhages at the disc margin and mild visual loss. Ultrasound of the optic nerve head revealed optic disc drusen in both eyes and this was also confirmed by the control photograph. Optic nerve head drusen should be considered in the differential diagnosis of a diabetic patient presenting with disc edema.

PURPOSE: To evaluate the safety and efficacy of a single intraoperative intravitreal injection of triamcinolone acetonide after phacoemulsification in patients with chronic idiopathic anterior uveitis or intermediate uveitis. SETTING: Dr. R.P. Centre for Ophthalmic Sciences, All India Institute of Medical Sciences, New Delhi, India. METHODS: This prospective randomized controlled study included 40 eyes (40 patients) with chronic idiopathic anterior uveitis or intermediate uveitis that had phacoemulsification with intraocular lens implantation. Twenty eyes received an intravitreal injection of triamcinolone acetonide (4 mg/0.1 mL) intraoperatively (triamcinolone acetonide group), and 20 received oral steroids (steroid group) postoperatively. Outcome measures were Early Treatment Diabetic Retinopathy Study best corrected visual acuity (BCVA), anterior chamber reaction, intraocular pressure (IOP) by applanation tonometry, and central macular thickness by optical coherence tomography. RESULTS: The mean BCVA (decimal) improved from a baseline of 0.13 +/- 0.14 to 0.64 +/- 0.32 in the triamcinolone acetonide group and from 0.05 +/- 0.06 to 0.61 +/- 0.36 in the steroid group (P = .74). There were no statistically significant differences between the 2 groups in postoperative anterior chamber reaction, IOP, or central macular thickness. Four patients in the triamcinolone acetonide group and 5 in the steroid group had recurrence of uveitis; 5 patients in the triamcinolone acetonide group had ocular hypertension. One patient in the triamcinolone acetonide group and 3 in the steroid group had cystoid macular edema postoperatively. CONCLUSION: A single intraoperative intravitreal injection of triamcinolone acetonide seemed to be a safe and efficacious route of steroid delivery during phacoemulsification in patients with chronic idiopathic anterior uveitis or intermediate uveitis and is recommended as a substitute for postoperative oral steroid administration.

AIM: To evaluate the effect of laser-assisted in situ keratomileusis (LASIK) on the measurement of retinal nerve fiber layer thickness by scanning laser polarimetry using customized corneal compensation in myopes. MATERIALS AND METHODS: Scanning laser polarimetry was performed on 54 eyes of 54 healthy patients with myopia using the glaucoma diagnostics variable corneal compensation (GDx VCC) instrument (Laser Diagnostic Technologies, San Diego, California) before and a week after LASIK. The various parameters were compared using the Student's t test. RESULTS: No statistically significant change was observed in any of the retinal nerve fiber layer parameters before and after LASIK. CONCLUSIONS: While the measurement of retinal nerve fiber layer thickness by scanning laser polarimetry is affected by anterior segment birefringent properties and LASIK would be expected to produce changes in the same, customized corneal compensation using the GDx VCC seems to adequately compensate for these changes.
