[Thrombophlebitis of left cavernous sinus secondary to acute right sphenoid sinusitis].

Isolated sphenoid sinusitis is a rare, potentially destructive entity. Presenting symptoms are often vague and non-specific therefore the diagnosis is made late when complications have had already occurred. The most frequent complications of sinusitis are the neurological ones--being serious life--threatening conditions.

[Cataract surgery in diabetic patients].

Purpose: Analysis of functional results, per- and postoperative complications after cataract surgery in diabetic patients.

Material And Method: Retrospective study including 100 non-diabetic patients and 50 patients with type II diabetes, with extracapsular extraction and IOL implantation in the postoperator chamber followed for 10.3-7.

[The ocular hypotensive effect of the combination of latanoprost with dorzolamide].

Objective: To analyze the hypotensive effect and ocular tolerance produced by the association of a topic carbonic anhidraze inhibitor (dorzolamide--Trusopt) and a prostaglandin derivative (latanoprost--Xalatan) in the treatment of the hypertensive glaucomas.

Material And Method: The study includes two steps: STEP I: A double-blind randomized prospective study which includes 32 eyes with primary open angle glaucoma, divided in two groups: group A, in which Trusopt is administrated for 7 days and then Xalatan is associated for another 7 days and group B, in which the order is reversed: for the first 7 days only Xalatan is administrated and then for another 7 days, Trusopt is associated in the treatment. The intraocular pressure and the secondary effects were assessed daily.

[The effect of chronic beta-blocker treatment on the evolution of primary open-angle glaucoma].

Unlabelled: Comparative analysis of the results of the trabeculectomy in primary open-angle glaucoma (POAG) when it was chosen as a primary treatment and when was preceded by chronic use of topic beta-blockers.

Material And Method: Retrospective study of 59 patients (group A) with primary trabeculectomy and 42 patients (group B) with topic beta-blockers treatment for at least 3 years subsequent to trabeculectomy was performed. The average postoperative follow-up period was 3 years and 5 months.

[Primary trabeculectomy in the surgery of primary open angle glaucoma].

Objective: Comparative analysis of the results of trabeculectomy in the surgery of primary open angle glaucoma (POAG) as the primary therapeutical approach and after the medical treatment failure.

Materials And Method: Retrospective study including two therapeutical groups: A (59 patients) with primary trabeculectomy; and B (60 patients) with trabeculectomy following a medical treatment failure; mean follow-up period was 3 years and 5 months.

Results: Postoperative drop in intraocular pressure was similar in the two groups; there is no statistical significant difference between the two groups regarding stationary disease (76.
