[Posterior staphyloma in the normal lenght eyeball--a case report]

The aim of the study is to present a case of posterior staphyloma in the eyeball of the normal length.

A 17-year-old boy underwent full ophthalmologic examination due to impaired vision in the right eye (R.E.) lasting for one month. The visual acuity of R.E. and L.E. was found to be 0.8 and 1.0, respectively; near visual acuity for both eyes--0.5, intraocular pressure in both eyes--16 mmHg. The anterior part of both eyes was normal. The R.E. ophthalmoscopy revealed the presence of posterior staphyloma near the temporal-upper optic disc margin accompanied by serous retinal detachment above the macula. The L.E. ophthalmoscopy--normal. The eyeball length 23 mm and posterior staphyloma depth 2.4 mm. Refraction test--normal without any vision defect. Additionally fluorescein angiography, US B and OCT confirmed the presence of posterior staphyloma of the right eye. During the 3-month follow up the retinal detachment markedly decreased.

The case report shown that posterior staphyloma may develop in the eyeball of normal length although its incidence is rare. New diagnostic methods, especially OCT, are very helpful in the clinical picture evaluation.
