An ophthalmic treatment device for photobiomodulation of a retina comprising: a treatment light source producing a continuous wave or quasi- continuous wave output beam having a wavelength in the range of 600nm to 1000nm and a power in the range of 1 mW to 500mW； a beam homogenizing module that homogenizes the output beam of the treatment light source； a beam shaping module that modifies the output beam profile to produce a treatment light beam with an annular light beam profile； and a beam delivery and viewing module that allows an Operator to observe and operate to deliver the treatment light beam to the treatment location on the retina with an intensity in the range of 1 mW/cm
