[The retro-equatorial muscular strapping. A technical adaptation of Cuppers's Faden-Operation. A preliminary report (author's transl)].

Reckoning up the Balance-sheet of about 300 Faden-operations performed during two years in blocking convergent squints, the Authors note that whether this operation is absolutely appointed in various forms of horizontal incomitances in which the spasmodic factor is prevalent on the other hand in moderate forms it does not seem to give better results than classic muscular surgery. After having detailed the characteristics and technical difficulties of this operation, first they mention that its effects are unforeseeable in spite of a previous careful clinical examination; then moreover, it has a binding character. In many cases reoperations allowed to notice a considerable sclerosis of the formerly operated muscle and neighbouring capsule. To avoid these drawbacks, instead of a muscular fastening, they make a retroequatorial strapping on the sclera. They describe the successive steps in their procedure, which appears having many benefits with regard to the original Faden-operation.

Subretinal fluid in primary rhegmatogenous retinal detachment: physiopathology and composition.

During retinal detachment, subretinal fluid is present, whose composition and physiopathology are still little known. Under normal conditions, osmotic and oncotic pressures help keep the retina in place, but the main retinal attachment force is provided by active transport in the pigment epithelium. Subretinal fluid composition varies according to detachment duration; total protein concentration in subretinal fluid increases with time. In addition, all proteins are qualitatively modified. The detached retina loses its oxygen supply, and it then uses the anaerobic pathway to degrade glucose. Thus, long-duration retinal detachments feature increased lactic acid and dextrose concentrations. Phospholipids are also increased in subretinal fluid, reflecting retinal degradation. This review presents data on the physiopathology and composition of the subretinal fluid in retinal detachments.

Spontaneous resolution of vitreomacular traction associated with diabetic macular edema.

PURPOSE: Little information is available about the natural history of vitreomacular traction (VMT) associated with diabetic macular edema. A few cases of spontaneous resolution of VMT associated with diabetic macular edema have been described, but have not been documented by optical coherence tomography (OCT). The authors report the spontaneous resolution of VMT associated with diabetic macular edema 1 month after the end of panretinal photocoagulation therapy (PRP). METHODS CASE REPORT: A 66-year-old woman presented with complicated proliferative diabetic retinopathy and diabetic macular edema associated with VMT, documented by OCT, in the right eye. Left eye examination showed complete PRP and ischemic maculopathy. PRP was immediately realized in the right eye in regard to the presence of complicated proliferative diabetic retinopathy. RESULTS: One month after the end of PRP, right eye visual acuity improved. OCT examination showed complete release of foveal posterior hyaloid traction, and significant reduction in foveal thickness. The follow-up was 1 year. At the end of follow-up, visual acuity slightly improved again; only a small residual foveal retinal thickening remained. CONCLUSIONS: The authors report spontaneous resolution of VMT associated with diabetic macular edema, probably facilitated by PRP, with concurrent reduction of macular thickness and visual improvement. As spontaneous resolution may occur in some eyes with diabetic macular edema associated with VMT, a period of observation after the end of the PRP may be considered prior to vitrectomy.

Comparative evaluation of efficacy and safety of ciprofloxacin and norfloxacin ophthalmic solutions.

The efficacy and safety of ciprofloxacin ophthalmic solution 0.3% and norfloxacin ophthalmic solution 0.3% in the treatment of bacterial conjunctivitis and blepharitis were compared in a double masked randomised study. A total of 131 patients, 65 treated with ciprofloxacin (42 with conjunctivitis and 23 with blepharitis) and 66 treated with norfloxacin (39 with conjunctivitis and 27 with blepharitis) were enrolled in the study at five centres in France. In the efficacy population, pathogens were eradicated or reduced in 96% (24/25) of patients in the ciprofloxacin group and 89% (24/27) in the norfloxacin group. There was no difference between treatments with regard to eradication of particular pathogens. In the efficacy population, clinical cure or improvement was seen in 96% of the patients (24/25 in the ciprofloxacin group and 26/27 in the norfloxacin group). There were no significant differences between ciprofloxacin and norfloxacin with respect to improvements in four symptoms or ten clinical signs. No serious treatment-related adverse events were reported and both ciprofloxacin and norfloxacin were well tolerated.

Tubulointerstitial nephritis and uveitis syndrome (TINU syndrome) with unilateral neuroretinitis: a case report.

PURPOSE: To report a case of tubulointerstitial nephritis and uveitis syndrome (TINU syndrome) with unusual unilateral neuroretinitis. METHODS: An 11-year-old girl who developed anterior uveitis 3 months after acute tubulointerstitial nephritis, without any etiologic factors for either nephritis or uveitis, is presented. RESULTS: Several days after the anterior uveitis, the patient presented with unilateral optic disk edema associated with a serous retinal detachment of the posterior pole, never previously described in TINU syndrome, leading to the formation of perifoveal intraretinal exudates. CONCLUSIONS: In spite of these posterior lesions, clinical course confirmed the previously reported favorable visual outcome of TINU syndrome treated with corticosteroids. It appeared that ocular impairment in TINU syndrome could be more diffuse and more extensive than previously described. As well as the whole uveal tract, the retina and the optic nerve may also be the ocular targets of the idiopathic inflammatory response in TINU syndrome.

[A multifactorial etiologic approach to diabetic dyschromatopsia. Study of 100 diabetics].

Diabetic dyschromatopsia is frequent and is a true complication of diabetes mellitus. Causative factors other than retinopathy have been suggested, but they remain unclear. We have explored the color vision of 100 diabetics aged 16 to 65 (88 insulin-dependent, 12 non-insulin dependent) with Lanthony's D15 desatured panel. Degenerative complications were looked for, especially by fundoscopy and electrophysiological exploration of peripheral nerves using specific scoring. 73% of the diabetics had dyschromatopsia. Dyschromatopsia was significatively more frequent when retinopathy was present (26 out of 30 diabetics with retinopathy versus 47/70 without). We explain the absence of a strict parallelism between dyschromatopsia and retinopathy by the intervention of other factors. Whereas the equilibration of the diabetes was not different between the groups with or without dyschromatopsia, patient age, microalbuminuria, blood pressure and alcohol intake were higher in patients with dyschromatopsia. The greater prevalence of peripheral neuropathy in patients with dyschromatopsia, confirmed by electrophysiology, and independently from the existence of retinopathy, is an indicator of the existence of neuronal disease, whose level remains to be determined. Our results are the indispensible preliminary step to a study of the respective importance of these pathogenic factors.

[Functional outcome of advanced chronic glaucoma after trabeculectomy].

We studied the risk of sudden loss of visual fields after trabeculectomy on 17 eyes with primary open angle glaucoma and small residual visual fields. We think that it is possible to try to these patients filtering procedures with precautions before and during surgery.

[Surgical results in traumatic 6th nerve paralysis].

Authors distinguish complete sixth nerve palsies needing a supply procedure and incomplete palsies needing a classic procedure. Results in the second group are satisfactory. In case of complete palsies, the objective consists in obtaining primary gaze rectitude.
