Vitrectomy for epiretinal membranes: visual outcome and prognostic criteria.

The treatment of choice for epiretinal membranes (ERM) causing marked retinal distortion and substantial visual impairment remains vitreoretinal surgery. The purpose of this study was to evaluate the results of surgery performed in our department and to investigate the prognostic value of different factors such as preoperative best-corrected visual acuity (BCVA), pre-existing cystoid macular edema (CME), intra-operative peeling of the internal limiting membrane (ILM), age and duration of symptoms. Eighty-eight consecutive eyes of 88 patients were operated on for ERM from July 1998 to June 2000. Both idiopathic and secondary cases were included. In all cases the ERM was successfully removed from the fovea. Mean BCVA after surgery increased from Snellen 0.2 (hand motion (HM) - 0.6) to Snellen 0.5 (HM - 1.0) (p<0.0001). Our results confirm the efficacy of surgical removal of the ERM in improving the visual acuity. Although not statistically significant, mean postoperative BCVA was slightly better in the group without pre-existing CME (p>0.05) and in the group where peeling of the ILM was performed (p>0.05). The data suggest that early surgery is likely to decrease the risk of developing irreversible macular damage (p<0.05). Because accelerated nuclear sclerosis with visual impairment is a common phenomenon after vitrectomy, one might consider performing a phaco-emulsification at the same time, especially in the elderly.

Posterior uveitis: an under-recognized adverse effect of pamidronate: 2 case reports.

Ocular adverse effects of pamidronic acid are rare but well documented. Pamidronate, an inhibitor of bone resorption used primarily in the management of tumor-induced hypercalcemia and Paget's disease, is reported to cause conjunctivitis, anterior uveitis, and infrequently episcleritis and scleritis. It is hypothesized that an allergic or immunologic phenomenon caused by drug-indued immune complex formation is at fault. The reason why the uvea is a target organ is unclear. The acute inflammatory response seems unrelated to the dose of the drug, the way of administration, or the activity of Paget's disease or malignancy. We report two cases of pamidronate-induced posterior uveitis, following the WHO Causality Assessment Guide of Suspected Adverse Reactions. Uveitis and scleritis have been reported in association with a variety of topical, intraocular, periocular, and systemic medications. Seven criteria were proposed to establish causality of adverse events by drugs. Only systemically administered biphosphonates meet all seven criteria. Where pamidronate is currently considered as the drug of choice in diverse strategies, the adverse ocular effects should be well known to physicians in order to make rapid diagnosis and stop the drug causing adverse reaction.

Silicone oil tamponade in the vitreoretinal surgery.

This retrospective study aimed to evaluate the influence of a temporary silicone oil (SiO) tamponade on intraocular pressure (IOP). We reviewed 131 procedures with a temporary SiO tamponade for different indications. Visual outcome and anatomic results after the SiO removal were also analyzed. Relatively good visual and anatomic results can be achieved by a temporary SiO tamponade with an acceptable complication rate.

Silicone oil vs. gas for the treatment of full-thickness macular hole.

The purpose of this study is to evaluate the anatomic and visual outcomes, as well as the complications, of macular hole surgery with SF6-gas tamponade versus silicone-oil tamponade. Fifty-four (54) eyes with idiopathic macular hole underwent vitrectomy and peeling of the internal limiting membrane (ILM) around the hole. Nineteen (19) eyes were treated with SF6-gas tamponade (group 1) and the other thirty-five (35) eyes with silicone-oil tamponade (group 2). An excellent anatomic success rate was obtained in both groups (94.7% in group 1 and 97.1% in group 2). Nevertheless, the postoperative visual acuity (VA) in the group treated with silicone-oil tamponade was significantly better than in the group treated with gas tamponade (P = 0.0217). Forty-seven (47) of the eyes in group 1 and 74% in group 2 achieved a VA = 0.4 or better. The most frequent potentially vision threatening complication we observed was RPE alterations in 35% of the eyes in group 1 and in only one eye in group 2. None of the eyes developed a retinal detachment during the follow-up period. In conclusion, the treatment of idiopathic macular holes by vitrectomy and ILM peeling provides a very good anatomic success rate. An excellent recovery of visual acuity, up to 1.0, was more frequently observed in the group treated with silicone oil tamponade.

Adult respiratory distress syndrome. A histopathologic study.

The results of an anatomohistopathologic study carried out on subjects who died from various causes in resuscitation centers are reported with specific reference to the evolutive phases of the adult respiratory distress syncrome (ARDS). While a precise anatomohistopathologic diagnosis of non-clinically diagnosed ARDS in its initial phase is considered possible, the importance of recognizing this pathology in cadavers and living patients is emphasized because of the medico-legal implications involved.
