ABSTRACT
PURPOSE: To evaluate corneal thickness in eyes with normal tension glaucoma. MATERIAL AND METHODS: CCT (measured by specular microscope Topcon SP2000P) was evaluated in 70 eyes of 39 patients with diagnosed NTG, 35 women and 4 men in age 31-78 years (mean 68 years). RESULTS: Mean central corneal thickness measured by the specular microscope (between 11 and 1), was 523.7 microm in range 465-575 microm. Impact of CCT on results of Goldman aplanation tonometry was detected in 55.7% of NTG eyes--overestimated in 20% and underestimated in 35% of them. Corrected maximal IOP > 21 mmHg, was found in 14% of NTG eyes. CONCLUSIONS: Central corneal thickness measurement should be part of routine ophthalmological examination in glaucomatous patients (especially in NTG), being helpful in choice of optimal therapeutic strategy.

PURPOSE: Ocular ischemic syndrome (OIS) is often poorly diagnosed and treated as primary open angle glaucoma or later on, as neovascular glaucoma. We present a 54 year old male, treated topical since 23 years for glaucoma and sent to our clinic for trabeculectomy because of rapid worsening of vision on right eye with bilateral total excavation of optic disc. MATERIAL AND METHODS: Observational case report. RESULTS: Because of typical signs of IOS (iris neovascularization, mid-peripheral dot and blot hemorrhages in both eyes, narrowed arterioles in right eye, following examinations were performed: Doppler ultrasonography of carotid arteries, digital subtractional angiography of the carotid vessels and magnetic resonance angiography. The examinations showed occlusion of the right common carotid artery and with 80% stenosis of the left common carotid artery, occlusion of abdominal aorta. After phacoemulsification with implantation of intraocular lens because of rapid intumescence cataract in the right eye, and endarterectomy of left external carotid artery, the neovascularization of the iris regressed in both eyes. CONCLUSION: In case of iris neovascularization or mid-peripheral hemorrhages the Doppler sonography of carotid arteries should be performed. Quick cooperation between ophthalmologist, radiologist and vascular surgeon following endarterectomy seems to stop progressing changes of ocular ischemic syndrome.

PURPOSE: Presentation of two cases of malignant glaucoma following filtration surgery. MATERIAL AND METHODS: Two patients with primary angle closure glaucoma has been treated with trabeculectomy. Flat anterior chamber, elevated IOP and the presence of patent irydectomy has been diagnosed 1 and 5 weeks after operation respectively. First patient in spite of peripheral irydectomy, medication and pars plana vitrectomy had high IOP and flat anterior chamber and has lost her sight. Second patient has improved after pharmacological treatment. CONCLUSIONS: Malignant glaucoma is a rare, but very serious complication after trabeculectomy. A very close and regular postoperative examination is necessary for a quick pharmacological or operative intervention.

Thyroid orbitopathy (TO) requires often not only pharmacological treatment but also surgical procedures. The management contains orbital decompression (wall decompression, excision of fat), correction of lid retraction and strabismus operations on extraocular muscles. Authors describe indications for surgical procedures, methods of operations, results and complications of own material of 99 patients with TO treated in the Eye Clinic in Poznan and Plastic Surgery and Eye Clinic in Kobylniki from 1999 until 2003.

The aim of this paper is, to evaluate the efficacy of amniotic membrane transplantation for ocular surface reconstruction in patients with bullous keratopathy and chemical and thermal burns of cornea and conjunctiva. Amniotic membrane is a thin, semitransparent tissue forming an innermost layer of the fetal membrane, which contains a thick basement membrane with a single layer of epithelium and avascular matrix. This transplantation promotes normal conjunctival epithelization while suppressing fibrosis formation. Amniotic membrane transplant may be considered as an alternative method for treating ocular surface reconstruction in patients with thermal and chemical burns. Authors suggest that this method of treatment is not efficient in patients with bullous keratopathy.
