The answer to âwhat is CRM processâ may sound straightforward but it entails approaches, systems and technologies to compile information on customers across different channels or points of contact between your company and the customers.
Any type of vision loss (e.g. blindness, blurred vision, double vision, etc.) is a symptom of great concern. Many of the causes are very serious medical conditions. Certain types of vision changes can be a medical emergency where delay can lead to loss of sight (e.g. for causes such as glaucoma, eye injury, retinal detachment) or loss of life (e.g. for causes such as stroke, TIA, etc.).
Brain or eye tumours are rarely the cause of loss of vision. Gradual loss of vision can be a symptom of a growing tumour-but it is important to keep a sense of proportion, and remember: gradual loss of vision is very common but brain and eye tumours are very, very rarely the cause.
