• Retinal telangiectasia only
• Telangiectasia and exudation
• Mild disease (1, 2) Laser photocoagulation/cryotherapy
• If thick exudation is present, laser treatment may not be particularly useful, as it may not be able to reach the vessels, and cryotherapy is preferred.
• Cryotherapy is used in Coat's disease especially in patients presenting with exudative disease and retinal detachment, which corresponds to stages 1–3b of Shields' classification.
• When laser photocoagulation is not possible, even being the treatment of choice for mild Coat's disease, cryotherapy is utilized and believed to be more effective than laser in more advanced cases.
• Like laser photocoagulation, it may require multiple sessions, although if excessive it may conversely lead to an increase in subretinal exudation and an increase in retinal detachment.
• Therefore, it is advisable to use it for only up to two quadrants at a time, with a month gap between treatments.
