Menurut Dr Ong, tiada sebab utama dan punca berlakunya glaukoma, namun terdapat faktor yang boleh dikaitkan dengan penyakit ini, iaitu sejarah keluarga, diabetes yang tidak terkawal, dan rabun jauh. Bagaimanapun, faktor genetik dilihat berkait rapat dan mempengaruhi kebarangkalian seseorang itu menghidap glaukoma. Jika ada ahli keluarga anda pernah menghidap glaukoma jenis kronik, ahli keluarga lain juga harus disaring lebih awal kerana mereka berisiko.

According to Dr Ong, the signs and symptoms of a blocked tear duct include excessive tearing, redness of the white part of the eye, recurrent eye infection or inflammation, painful swelling near the inside corner of the eye, crusting (formation of a hard, outer layer) of the eyelids, and mucous or pus discharge from the lids and surface of the eye. An ophthalmologist will be able to diagnose a blocked tear duct, and the treatment options will depend on the level of the obstruction and the severity of the tear duct blockage. The treatment options are external dacryocystorhinostomy (DCR) surgery, endoscopic DCR surgery, stenting or intubation, and dilation and flushing of the tear ducts. Treatment is usually successful more than 90% of the time.
