O\u010dni skotomi predstavljaju ta\u010dkaste vidne defekte. Mogu nastati kao crne ili sive mrlje, \u017eice ili pau\u010dina koja \u0161eta vidnim poljem. Prilikom poku\u0161aja direktnog gledanja u njih, sti\u010de se utisak da se udaljavaju.<\/p>\n

O\u010dni skotomi naj\u010de\u0161\u0107e su izazvani usled promena udru\u017eenih\u00a0 sa starenjem u vitreusnom telu te unutra\u0161njost o\u010dnih jabu\u010dica\u00a0 postaje te\u010dnija. Mikroskopska vlakna unutar vitreosnog tela formiraju klupko i mogu odavati sitne senke na retini, koje deluju kao skotomi.<\/p>\n

Iznenadan porast u broju skotoma zahteva brzu medicinsku intervenciju, pogotovo ako je kombinovana sa perifernim vidom ili gubitkom trepavica.<\/p>\n

 <\/p>\n

Simptomi<\/h2>\n

Simptomi o\u010dnih skotoma uklju\u010duju:<\/p>\n

Ta\u010dkaste promen u vidnom polju koje delujukao tamne mrlje ili providne \u017eica u vidu plutaju\u0107eg materijala<\/p>\n

Ta\u010dke koje se pomeraju zajedno sa pokretima o\u010diju<\/p>\n

Ta\u010dke koje su najuo\u010dljivije tokom gledanja u ravnu povr\u0161inu<\/p>\n

Ta\u010dke koje se smiruju i udaljavaju od vidnog polja<\/p>\n

Ve\u0107i broj skotoma nego uobi\u010dajeno<\/p>\n

Iznenadan nastanak o\u010dnih skotoma<\/p>\n

Odbljesci svetala<\/p>\n

Gubitak perifernog vida<\/p>\n

 <\/p>\n

Uzroci<\/h2>\n

Mogu\u0107i uzroci o\u010dnih skotoma su:<\/p>\n

Promene udru\u017eene sa staro\u0161\u0107u: starija \u017eivotna dob uslovljava manjak te\u010dnosti u vitreusnom telu \u0161to odvla\u010di o\u010dnu jabu\u010dicu od donje povr\u0161ine. Vitreusno telo tada po\u010dinje da se sme\u017eurava i postaje krto. Delovi debris (mrtvih \u0107elija) mogu blokirati prolaz svetlosti ka oku i formirati manje senke na retini.<\/p>\n

Zapaljesnki process zadnje rgije oka: posteriorni uveitis koji zahvat slojeve uvee u zadnjem delu o\u010dne jabu\u010dice i nastanak skotoma.<\/p>\n

Krvarenje u oku<\/p>\n

Cepanje retine<\/p>\n

Kidanje retine: oslabljenje vitrusnog tela mo\u017ee usloviti kidanje retine. Nele\u010deno kidanje retine mo\u017ee voditi odlubljivanju retine dok nele\u010dena dislokacija mo\u017ee izazvati trajni gubitak vida.<\/p>\n

 <\/p>\n

Faktori rizika<\/h2>\n

Faktori rizika za nastanak skotoma uklju\u010duju:<\/p>\n

Starost (preko 50 godina)<\/p>\n

Kratkovidost<\/p>\n

Traumu oka<\/p>\n

Zapaljenje o\u010dnih struktura<\/p>\n

Dijabetesnu retinopatiju<\/p>\n

Komplikacije nakon katarakte hirurgije<\/p>\n
