Aerobic exercise and intraocular pressure in normotensive and glaucoma patients.

BACKGROUND: With the increasing number of people participating in physical aerobic exercise, jogging in particular, we considered that it would be worth knowing if there are should be limits to the exercise with regard to the intraocular pressure (IOP) of the eyes. The purpose of this study is to check IOP in healthy and primary glaucoma patients after aerobic exercise. METHODS: 145 individuals were subdivided into seven groups: normotensives who exercised regularly (Group A); normotensives in whose right eye (RE) timolol maleate 0.5% (Group B), latanoprost 0.005% (Group C), or brimonidine tartrate 0.2% (Group D) was instilled; and primary glaucoma patients under monotherapy with beta-blockers (Group E), prostaglandin analogues (Group F) or combined antiglaucoma treatment (Group G) instilled in both eyes. The IOP of both eyes was measured before and after exercise. RESULTS: A statistically significant decrease was found in IOP during jogging. The aerobic exercise reduces the IOP in those eyes where a b-blocker, a prostaglandin analogue or an alpha-agonist was previously instilled. The IOP is also decreased in glaucoma patients who are already under antiglaucoma treatment. CONCLUSION: There is no ocular restriction for simple glaucoma patients in performing aerobic physical activity.

The efficacy of intravitreal povidone iodine application in experimental Staphylococcus epidermidis endophthalmitis.

AIM: The aim of the current study is to evaluate the role of povidone iodine (PVI) in the management of experimental bacterial endophthalmitis in young rabbits. METHOD: Twenty white rabbits were used. Colony-forming units (CFU) of Staphylococcus epidermidis were injected intravitreally into the right eye of each animal. Injected eyes were evaluated clinically daily (anterior and posterior segment examination), and when clinical signs of endophthalmitis appeared, an injection of 0.1 ml PVI was made intravitreally. In group 1 (n = 10), the injected concentration of PVI was 0.1%, and in group 2 (n = 10) the concentration was 0.2%. At the end of the observation period, vitreous sample culture was made, and vitreous and retina specimens were taken for light histology examination as well. results: Group 1 eyes did not show any signs of clinical improvement. Vitreous culture showed the presence of 10(8) CFU/ml of S. epidermidis. Histological examination indicated acute inflammation. Group 2 animals presented a clear gradual regression of the inflammation. Vitreous culture for S. epidermidis proved to be sterile. Histological examination indicated chronic inflammation. CONCLUSIONS: Intravitreal injection of 0.2% PVI is likely to inhibit bacterial endophthalmitis of rabbit eyes due to S. epidermidis.

Sulcus implantation of a 3-piece, 6.0 mm optic, hydrophobic foldable acrylic intraocular lens in phacoemulsification complicated by posterior capsule rupture.

To evaluate the safety of implanting a 3-piece, 6.0 mm optic, foldable acrylic intraocular lens (IOL) in cases of posterior capsule rupture during phacoemulsification. Department of Ophthalmology, Ahepa Hospital, Aristotle University Medical School, and Interbalkan Medical Center, Thessaloniki, Greece. This prospective noncomparative case series included 28 eyes (28 patients) having phacoemulsification complicated by extensive posterior capsule rupture with or without vitreous loss. In all eyes, a 3-piece, 6.0 mm optic, foldable acrylic IOL (AcrySof MA60BM, Alcon) was implanted in the sulcus. Postoperative examination included best corrected visual acuity (BCVA), anterior segment biomicroscopy, IOL centralization and position, intraocular pressure (IOP), and fundus biomicroscopy. The follow-up was 6 months. The most common postoperative complications were transient corneal edema in 12 eyes and increased IOP in 11 eyes. Slight asymptomatic decentralization from the center of the pupil (1.0 to 2.0 mm) and pseudophacodonesis were observed in 5 eyes each. Friction of the IOL with the iris occurred in 1 eye. Clinically significant cystoid macular edema occurred in 3 eyes. The final BCVA was between 20/15 and 20/25 in 18 patients, 20/30 in 2, between 20/40 and 20/50 in 4, and between 20/60 and 20/200 in 4. AcrySof IOL implantation in the sulcus during phacoemulsification complicated by posterior capsule rupture preserved the advantages of small-incision surgery. The postoperative behavior and centralization of the IOLs resembled those of poly(methyl methacrylate) lenses.
