[Macular hole surgery without postoperatory < > down positioning. Pilot study].

PURPOSE: To evaluate the visual and anatomical outcomes of macular hole surgery using phacoemulsification, vitrectomy and intraocular gas tamponade without the use of postoperative face down positioning. METHODS: Phacoemulsification with an intraocular lens implant, followed by vitrectomy with internal limiting membrane peeling and perfluoropropane (C3F8), was performed in patients with stage 3 or 4 macular holes. After surgery, patients had to avoid the supine position for 15 days. Patients with a gas level <50% during the first week had a fluid-gas exchange. Visual acuity and closure of the macular hole were evaluated after 1 year of follow-up. RESULTS: 20 eyes of 20 patients, aged 60 to 75 years (median age 68 years), were included in this study. The best initial visual acuity ranged from 0.05 to 0.13 (ETDRS), with the median being 0.06. The final visual acuity was 0.05 to 0.30 with a median of 0.10. A statistically significant improvement (p=0.001, Wilcoxon) was found. The anatomic postoperative results revealed 90% (n=18) of the macular holes were closed while 10% (n=2) were not. CONCLUSIONS: Macular hole surgery has, in general, good results and patients can achieve improvement in their visual acuity without the need for uncomfortable and unbearable post operative posture positions.

[Choroidal effusion and retinal detachment after capsulotomy with YAG-LASER].

CASE REPORT: A 74-year-old woman presented complaining of blurred vision in her left eye. She had an anterior chamber lens in both eyes and an opaque posterior capsule in her left eye, for which a YAG-LASER capsulotomy was performed. Thirteen days later she re-presented with a choroidal effusion and a retinal detachment requiring surgery. DISCUSSION: There is no consensus as to the exact time at which a capsulotomy should be done. Timing of the procedure requires evaluation as a whole and consideration of the potential complications of IOL dislocation, recurrent uveitis, ocular hypertension and the most devastating choroidal effusion and retinal detachment.

[Vitreous surgery in paediatric population. Visual and anatomic outcomes].

PURPOSE: To determine the anatomic and visual outcome of children that had undergone vitreoretinal surgery. METHOD: 229 clinical files where analyzed at our center, were included 73 patients, 77 eyes. We considered those who were 18 years old or younger and had undergone retinal surgery, retinopathy of prematurity (ROP) was excluded. RESULTS: The mean age was 10 years; the main indication for surgery was retinal detachment. Trauma and congenital and developmental abnormalities where found in 80% of the ocular pathology involved. 90.9% of the patients had an initial visual acuity of light perception to counting fingers. Final visual acuity ranged from counting fingers to 1.0 in 41.6%. There was no statistical significance between initial visual acuity and the final (p = 0.782) neither was the time of surgery and the final visual acuity (p = 0.454). 12.5% presented total retinal detachment and the macula was involved in 63.6% of all patients. Vitrectomy and retinopexy was the preferred surgery. Silicon oil was used in 58.4%. Retinal attachment was achieved in 63% of the patients after 6 months. CONCLUSION: In this kind of patients the ocular characteristics of the vitreous, made the surgery a very difficult procedure, and the final success include the visual rehabilitation.
