[Tuberculous retinitis with associated periphlebitis].

CASE REPORT: A female 23 years old, from Equador, was referred to us because of a vision decrease in her left eye. Fundus exploration demonstrated an inflammatory chorioretinal lesion with associated periphlebitis. Serology results showed positive for PPD. A vitreous biopsy was carried out together with tuberculosis prophylactic treatment with isoniacide (300 mg/day); the clinical findings improved. Finally, PCR test was positive for mycobacterium tuberculosis. In consequence, therapeutic treatment for tuberculosis was initiated. DISCUSSION: Due to the current increase in prevalence of tuberculosis, we should always take this into account as a possible etiology when dealing with cases of chorioretinitis.

[Study of the relationship between retinal and renal microangiopathy in patients with diabetes mellitus type 1].

The similarities in the vascularization of the retina and the kidney give rise to the complications of diabetes mellitus in the small vessels (microangiopathy) that appear in both organs. The present study presents the prospectively obtained results along 10 years in 104 diabetic type 1 patients, with the characteristics not to present microalbuminuria nor diabetic retinopathy at the beginning of the study; the results bear as objective the establishment of the relation between the presence of proliferative diabetic retinopathy and microalbuminuria, taking into account different factors of epidemiological risk: gender, duration of diabetes, presence of diastolic hypertension, levels of HbAlc, and blood lipids. The results obtained indicate a 10 years of follow-up incidence of diabetic retinopathy of 37.50% (being the proliferative form 13.46%) and the incidence of microalbuminuria is of 20.19%. The appearance of proliferative diabetic retinopathy is associated to the presence of diastolic hypertension, while the appearance of microalbuminuria is related to the elevation of levels of HbAlc. The results obtained in the proliferative diabetic retinopathy and microalbuminuria incidence are similar to those of other authors. At the end of the study four groups of patients are configured depending on whether they present proliferative diabetic retinopathy and/or microalbuminuria. The results obtained in the present study suggest the possible existence of two populations of diabetic patients, one that would develop proliferative diabetic retinopathy and renal injury, and a second population in which only would appear proliferative diabetic retinopathy.

[Anterior optic neuritis do to ulcerative colitis].

PURPOSE/METHODS: We present the case of a 27 year old woman with acute bilateral loss of vision associated with abdominalgia, bloody diarrhea and arthralgia. In the present article, the different forms of ocular complications in relationship to chronic intestinal inflammations and their possible causes are discussed. RESULTS/CONCLUSIONS: On examination, bilateral anterior uveitis associated to a picture of optic nerve lesion compatible with a bilateral anterior optic neuritis was observed. The patient was diagnosed of ulcerative colitis by intestinal biopsy. The ocular affectation resolved after the ulcerative colitis was treated with systemic mesalamine.

[Results in the treatment of acute endophthalmitis by vitrectomy using limbal incision].

PURPOSE: To describe the results obtained in the treatment of acute onset endophthalmitis after cataract surgery in our center using vitrectomy with corneal limbal incisions. METHODS: Study carried out in 12 patients with acute endophthalmitis after cataract surgery in whom a posterior vitrectomy by limbic incisions was performed followed by intravitreal injections of antibiotics (vancomycin + ceftazidime/amikacin) with systemic and topical antibiotic and corticosteroid treatment in the post-operative period. RESULTS: The incidence of endophthalmitis in our center was 0.92%. The most frequently isolated microorganism was Staphylococcus epidermidis (4 cases, 33.33%). Four cases were negative (33.33%). A visual acuity equal to or greater than 0.5 at three months was obtained in 6 patients (50%). Only one case required a second administration of intravitreal injections. One patient suffered vitreal hemorrhaging in the post-operative period, and no other complications were observed in the remaining patients. CONCLUSIONS: We consider that vitrectomy through limbal incisions is a valid alternative for acute onset endophthalmitis treatment.
