The Brain Can Regulate Glaucoma Progression

The most recent research shows that human brain could actually be able to regulate progression of glaucoma and other neurodegenerative diseases. These results have implications in the pursuit of neuro protective therapies.

Glaucoma is a neurodegenerative disease where patients lose seemingly random patches of vision in each eye. Scientists have long thought that glaucoma’s progression is independent of – or uncontrolled by – the brain. However, the recent study found that the progression of glaucoma is not random and that the brain may be involved after all. Moreover, it has been stated that patients with moderate to severe glaucoma maintained vision parts of the visual field in the better eye which were lost in the other eye – like two puzzle pieces fitting together (a “jigsaw effect”).

This pattern of vision loss is in stark contrast to loss from a brain tumor or stroke, which causes both eyes to develop blind spots at the same location. This suggests some communication between the eyes must be going on and that can only happen in the brain. Scientists also found that the “jigsaw effect” begins at the earliest stages of glaucoma and discovered clues as to which part of the brain is responsible for vision optimization in the face of glaucoma’s slow destruction of sight.

The work has further illustrated that the brain will not let the eye lose control of the same function on both sides of the brain if that can be avoided. The progression of Alzheimer’s and Parkinson’s diseases, which have neuro-degenerative biology similar to glaucoma, may also be actively mediated by the brain. It seems likely that the same kind of protective mechanism will be at work with other neuro-degenerative disorders. The researchers say that if the brain regulates neuro-degeneration – that is, if the brain controls how it loses control – then future studies should be able to look for opportunities to slow or stop the progression of these diseases.

doktor medicine, specijalista oftamologije at Klinika Svjetlost, Banja Luka | Website | + posts

Još od ranog djetinjstva bio sam oduševljen oftalmologijom, za mene najljepšom granom medicine. Pošto sam ujedno bio i dijete profesora oftalmologije, za mene je put moje karijere bio sasvim jasan i vidljiv. Nakon završetka srednje škole i uspešnog okončanja studija na Medicinskom fakultetu Banja Luka, radio sam sve što je bilo moguće kako bih se jednog dana mogao zvati i „oftalmologom.“ Sreća mi se osmijehnula, te sam nedugo po završteku studija dobio specijalizaciju iz oftalmologije u Kliničkom centru Banja Luka.

Trud i rad svakog ambicioznog i vrijednog studenta je bezvrijedan ako uz njega nije talentovan, požrtvovan i nesebičan mentor. U mom slučaju, to su bila dvojica ljudi koji su mi omogućili da u profesionalnom smislu postanem ovo što danas jesam. Prva osoba je moj pokojni otac, koji mi nije samo prenio ljubav prema oftalmologiji, nego je bio i najveća podrška mojoj karijeri. Druga osoba je moj „drugi otac“, prof. Nikica Gabrić, osnivač i vlasnik Klinika Svjetlost. On me je učio ne samo oftalmologiji i najnovijim vještinama, nego i filozofiji i psihologiji života. Zahvaljujući njemu, danas sam ne samo bolji oftalmolog, nego i bolji čovjek.

Liječenje bolesti oka nije uvijek lako, ali je sigurno uvijek interesantno. Živjeti i raditi u zemlji u razvoju i regionu punom izazova nije nikada bez uzbuđenja. Stoga sa ponosom mogu da kažem da sam bio dio tima koji je, sada već davne 2008. godine, prvi put izveo operaciju laserske korekcije dioptrije u Bosni i Hercegovini. Danas su refraktivne hirurške procedure, kao što su LASIK, Epi-LASIK, PRK i LASEK dio moje svakodnevne rutine i istinski nikada ne bih mogao biti srećniji zbog toga.

Osim mojih svakodnevnih stručnih i naučnih aktivnosti, uživam i u menadžerskim poslovima. Već skoro osam godina na čelu sam Klinike Svjetlost u Banjaluci. Svi moji saradnici, doktori i medicinske sestre, su vrijedni mladi ljudi na koje sam svaki dan sve više ponosan.
