Getting asylum on the purpose of being queer, It depends on your country where you came from. Moreover, Glaucoma is not a condition to get asylum in Germany. The court does not care about it, unless the health condition is really life threatening.
Most probably you have failed your studies, now the ABH asking you go leave Germany right ? I understand. It happens. In the eyes of the court, you have no reason to stay in Germany unless you Syrian, Palestinian or Sudanese. You have no chance at all. My asylum was rejected within few weeks, I am telling you from my experience. If you want to stay, you have two ways, getting married or Ausbildungsduldung.
